DETAILED DESCRIPTION OF THE INVENTION Definitions As used herein, "bacterial preparation" refers to a composition that includes bacterial spores and / or vegetative bacteria, which can be provided in a preservative. The preservative may include, for example, any of a variety of preservative compositions used in preparations of commercially supplied spores (bacterial or fungal), vegetative bacteria or fungi. Such preservatives may include, for example, a chelant, a surfactant, a buffer, water or the like. The microbial preparation, for example, can digest or degrade society such as fat, oil, mineral fat, sugar, protein, carbohydrates or the like. As used herein, percent weight (% -p), percent by weight,% by weight and the like are synonyms that refer to the concentration of a substance as the weight of that substance divided by the weight of the composition and multiplied by 100. As used herein, boric acid salt and borate salt are used interchangeably to refer to a salt such as potassium borate, monoethanolamine borate or another salt obtained by or which may be visualized as being obtained by neutralization of boric acid. The weight percent of a boric acid salt or borate salt in a composition of the present invention can be expressed either as a percentage weight of the ion containing negatively charged boron, for example, the portions of borate and / or boric acid , or as the percentage weight of the entire boric acid salt, for example, both the negatively charged portion and the positively charged portion. Preferably, the percentage weight refers to the whole salt of boric acid. The per hundred by weight of cyclic acid salts, or other acid salts, may also be expressed in these forms, preferably with reference to the entire salt of the acid. As used herein, the term "total boron compound" refers to the sum of the borate and boric acid moieties. As used herein, "basic or alkaline pH" refers to a pH greater than 7, greater than or equal to 8, from about 8 to about 9.5, from about 8 to about 11, greater than about 9, or about 9. to approximately 10.5. As used herein, substantially free of sodium ion refers to a composition that includes less than about 1% sodium ion. The embodiments of compositions according to the present invention may include less than 1% by weight of sodium ion, less than 0.75% by weight of sodium ion, less than 0.5% by weight of sodium ion, less than 0.25% by weight. weight of sodium ion, less than 0.2% by weight of sodium ion, less than 0.15% by weight of sodium ion, less than 0.1% by weight of sodium ion, less than 0.05% by weight of sodium ion. Each of these quantities can be modified by the term "approximately". As used herein, the terms "floor material" or "floor" refers to any horizontal surface on which a person may walk. A material for floor or floor can be made of an inorganic material, such as ceramic mosaic or natural stone (for example, quarry mosaic), or an organic material, such as epoxy, a polymer, a rubber or an elastic material . The material for floor or floor can be in any of a variety of environments, such as a restaurant (for example, a fast food restaurant), an establishment for processing and / or preparing food, a slaughterhouse or trail, a plant of packing, a plant for the production of organic fats, a kitchen or the like. As used herein, the phrases "coefficient of friction" and
"slip resistance" can be defined with respect to any of a variety of standard publications, such as ASTM Standard D-2047, "Coefficient of Static Friction of Floor Surfaces Coated with Wax According to Measurement by James Machine" and a report by the ASTM Committee D-21 that indicated that a floor that has a static friction coefficient of not less than 0.5 as measured by this test is recognized to provide a non-hazardous walking surface. This value is rated in NBS Technical Note 895"A General Perspective of Floor Slip Resistance, with Annotated Bibliography "by Robert J. Brungraber, where it is indicated that the value of 0.5 provides a safety factor and that most people, who stride normally, would be unlikely to slip on surfaces for which the value is greater than 0.3 to 0.35 Other important and similar standards include ANSI 1264.2-2001, ASTM C1028-89, ASTM F1679-00 (which refers to the English XL Tribometer), Test Method F1677-96 of ASTM, and UL 410 ( 1992) Each of the standards in this paragraph is hereby incorporated by reference, as used herein, the term "approximately" which modifies the amount of an ingredient in the compositions of the invention or used in the methods of the invention relates to the variation that may occur in the numerical quantity, for example, by means of typical methods of measuring and handling the materials used to make the concentrates or the solutions of use in the real world; by differences in the manufacture, source or purity of the ingredients used to make the compositions or carry out the methods; and the similar ones. Modified or not by the term "approximately", the claims include equivalents of the amounts. Stabilized Microbial Preparation The present invention relates to a stabilized microbial preparation that includes a borate salt and microbes. The microbes can be in the form of spores (bacterial or fungal), vegetative bacteria or fungi. The microbial preparation may include, for example, spores or mixture of spores that can digest or degrade dirt such as fat, oils (eg, vegetable oils or animal fat), proteins, carbohydrates or the like. The microbial preparation can also produce enzymes that aid in the degradation of dirt such as mineral fat, oil, fat, proteins, carbohydrates or the like. The borate salt may include any of a variety of boric acid salts, for example, certain alkali metal salts or alkanolamine salts. The boric acid salt can provide a source of alkalinity for a cleaning composition that includes the stabilized microbial preparation. The boric acid salt can provide advantageous stability to the microbial preparation as compared to a conventional microbial preparation employed, for example, in cleaning compositions. Conventional microbial preparations that start with, for example, 104 live bacteria or spores, after four months, may contain only 103 or even only 1 O2 of living organisms. That is, they lose one or two logs of active organisms, which can decrease the amount of dirt removed, digested or degraded. In one embodiment, the stabilized microbial preparations present lose less than one or two logs, or less than one log, of activity for four months. This provides a longer shelf life for the product that contains the microbial preparation. In one embodiment, the present stabilized microbial preparation is a component of a cleaning composition.
Although not limited to the present invention, the microbial preparation can be viewed as a source of cleaning enzyme or detergent in the cleaning composition. Such a cleaning composition may also include additional enzymes, not produced by the microbial preparation in situ. The microbial preparation can produce, for example, enzymes such as proteases, lipases and / or amylases. The composition may also include other added enzymes such as, for example, proteases, lipases and / or amylases. Although not limiting to the present invention, the added enzymes can be seen as providing immediate cleaning by application of the cleaning composition and the microbial preparation can be seen as a persistent cleaning provider since the microbes remain in the article to be cleaned, even after rinsing. Most cleaners can only provide dirt removal which is really just moving the dirt from one surface or location (for example, one floor) to another (for example, a drain). In certain embodiments, the cleaning compositions included in the present stabilized microbial preparation can provide both soil removal and persistent dirt reduction by persistent enzymatic breakdown of dirt. Cleaning compositions including the present stabilized microbial preparations can be used for a variety of purposes, including as a floor cleaner, a cement cleaner, such as a floor and drain cleaner and grease degreaser / digestive in combination, as a digestive fat in grease traps, for treatment of effluents and / or waste water (for example, reduction of fats, oils and mineral fats), in the municipal water treatment, as a fat digestive in treatment plants, or for black and gray water treatment on cruise ships. Although not limiting to the present invention, it is believed that stable microbial present compositions can undo grease or oil on a surface. Breaking the grease or oil can release other dirt stuck in the grease or oil. Accordingly, the present composition can clean a surface. In one embodiment, the present invention includes a method that includes repeating the application of the present stable microbial composition. For example, the present method may include the daily application. The application for 5 to 14 days can clean a slightly dirty surface. The application for three to six weeks can clean a very dirty surface. Boric Acid Salts The present invention relates to a stable microbial cleaning composition that employs one or more boric acid salts to provide improved stability of the microbial preparation, even at basic pH. Suitable boric acid salts can provide alkalinity to the stable microbial cleaning solution. Such salts include boric acid alkali metal salts; boric acid salts of amine, preferably boronic acid alkanolamine salts; and the like; or a combination thereof. In certain embodiments, the boric acid salt includes potassium borate, monoethanolammonium borate, diethanolammonium borate, triethanolammonium borate, and the like, or a combination thereof. In one embodiment, the boric acid salt includes monoethanolamine borate. The boric acid salt, for example potassium borate or monoethanolamine, can be obtained by any of a variety of routes. For example, the commercially available boric acid salt, for example, potassium borate, can be added to the composition. Alternatively, the boric acid salt, for example potassium borate or monoethanolamine, can be obtained by neutralizing boric acid with a base, for example, a potassium-containing base such as potassium hydroxide or a base such as monoethanolamine. In certain modalities, the boric acid salt is soluble in the composition of the invention in concentrations in excess of 5 or 10% by weight, for example, in excess of 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20% by weight. The boric acid salt in the present compositions can be used in a maximum concentration up to its solubility limit. In certain embodiments, the boric acid salt can be soluble in the composition of the invention in concentrations up to 35% by weight, for example, up to 25, 30 or 35% by weight. In certain embodiments, the boric acid salt may be soluble from 12 to 35% by weight, from 15 to 30% by weight, or from 20 to 25% by weight, preferably from 20 to 25% by weight. The present compositions may also include any of the amounts or ranges of boric acid salt modified by the term "about". In one embodiment, alkanolamine borates, such as monoethanolamine borate, are soluble in higher concentrations than other salts of boric acid, particularly sodium borate. Alkanolamine borates, such as monoethanolamine borate, can be employed and are soluble in cleaning compositions present in the concentrations listed above, preferably up to about 30% by weight, preferably from about 20 to about 25% by weight . In one embodiment, this high solubility can be obtained at an alkaline pH, such as pH from about 9 to about 10.5. In one embodiment, potassium borate is soluble in higher concentrations than other metal salts of boric acid, particularly other alkali metal salts of boric acid, particularly sodium borate. Potassium borate can be employed and is soluble in the present enzyme cleaning compositions in the concentrations listed above, preferably up to about 25% by weight, preferably from about 15 to about 25% by weight. In one embodiment, this high solubility can be obtained at an alkaline pH, such as a pH from about 9 to about 10.5. The boric acid salt can provide desirable increases in the stability of the microbial preparation at a basic pH compared to other buffer systems suitable for maintaining a pH above about 7, above about 8, about 8 to about 11. , or from about 9 to about 10.5. Maintaining the alkaline pH can provide greater cleaning power. The present composition with stable bacteria may be substantially free of sodium ion. Advantageously, in compositions substantially free of sodium ion, the borate salts are soluble in higher concentrations than in the presence of the sodium ion. Unfortunately, sodium ion is a common counter ion for salts. Therefore, care must be taken to provide compositions according to the present invention that are substantially free of sodium ion. For example, compositions substantially free of sodium ion in accordance with the present invention can be made from the acidic forms of reagents, which are neutralized, as appropriate, by an alkanolamine or potassium hydroxide. For example, compositions substantially free of sodium ion according to the present invention can be made from salts other than sodium salts, for example potassium or alkanolamine salts. In one embodiment, the present compositions include sodium ion at a level at which sodium borate does not precipitate from the composition. One way to achieve such low sodium levels is to exclude the sodium salts from the composition or to exclude the sodium salts except the amphoteric surfactant. Preferably, even with sodium of an amphoteric surfactant the composition of the present invention is substantially free of sodium ion. The present cleaning compositions substantially free of sodium ion may include borate salts up to concentrations of about 35% by weight, for example, from about 15 to about 30% by weight. In one embodiment, this high solubility can be obtained at an alkaline pH, such as pH from about 9 to about 10.5. Compositions including borate salts and substantially free of sodium ion can provide desirable increases in the stability of the microbial preparation at a basic pH compared to other suitable buffer systems to maintain a pH above about 7, above about 8, from about 8 to about 1, or from about 9 to about 10.5. Maintaining an alkaline pH can provide greater cleaning power. In certain embodiments, alkanolamine borate is present from about 5 to about 35% by weight, from about 10% by weight to about 30% by weight, from about 10% by weight to about 20% by weight, from about 5% by weight up to about 15% by weight, or from about 15% by weight to about 25% by weight. In certain embodiments, the alkanolamine borate is present from about 5% by weight to about 10% by weight, from about 15% by weight to about 20% by weight, from about 25% by weight to about 30% by weight of the composition. Such a formulation may be substantially free of sodium ion. The present compositions can also include any of the amounts or ranges of monoethanolamine borate not modified by the term "about". In certain embodiments, the monoethanolamine borate is present from about 10% by weight to about 20% by weight, from about 5% by weight to about 15% by weight or from about 15% by weight to about 25% by weight. In certain embodiments, the monoethanolamine borate is present from about 5% by weight to about 10% by weight, from about 15% by weight to about 20% by weight, from about 25% by weight to about 30% by weight of the composition. Such a formulation may be substantially free of sodium ion. The present compositions can also include any of the amounts or ranges of monoethanolamine borate not modified by the term "about". In certain embodiments, the boric acid salt is present from about 5 to about 35% by weight, from about 10% by weight to about 30% by weight, from about 10% by weight to about 20% by weight, from about 5% by weight. % by weight up to about 15% by weight, or from about 15% by weight to about 25% by weight. In certain embodiments, the boric acid salt is present from about 5% by weight to about 10% by weight, from about 15% by weight to about 20% by weight, from about 25% by weight to about 30% by weight of the composition. Such a formulation may be substantially free of sodium ion. The present compositions may also include any of the amounts or ranges of boric acid salt not modified by the term "about".

Nonionic Surfactant The nonionic surfactants useful in the invention are generally characterized by the presence of a hydrophobic organic group and an organic hydrophilic Neo group and are typically produced by the condensation of an aliphatic, alkyl aromatic or polyoxyalkylene hydrophobic organic compound with a moiety of hydrophilic alkaline oxide which in common practice is ethylene oxide or a product of the polyhydration thereof, polyethylene glycol. Virtually any hydrophobic compound having a hydroxyl, carboxyl, amino or amido group with a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration adducts, or mixtures thereof with alkoxylenes such as propylene oxide to form an active agent of non-ionic surface. The length of the polyoxyalkylene hydrophilic portion that is condensed with any particular hydrophobic compound can be easily adjusted to give a water-dispersible or water-soluble compound having the desired degree of balance between the hydrophilic and hydrophobic properties. Non-ionic surfactant of EOPO An example of useful non-ionic surfactants used with silicone surfactants are polyether compounds prepared from ethylene oxide, propylene oxide, in a homopolymer with grafted portion or a block or heteric copolymer.

Surfactants that include at least one block of a polyoxypropylene and that have at least one other polyoxyethylene block attached to the polyoxypropylene block can be used. Additional blocks of polyoxyethylene or polyoxypropylene may be present in a molecule. These materials having an average molecular weight in the range from about 500 to about 15,000 are commonly available as PLURONIC (R) manufactured by BASF Corporation and available under a variety of other registered trademarks of their chemical suppliers. In addition, PLURONIC (R) R (PLURONIC reverse structure) are also useful in the compositions of the invention. Additionally, the alkylene oxide groups used with an alcohol and an alkylphenol, a fatty acid or other such group, may be useful. A useful surfactant may include a linear alcohol of 6 to 24 capped polyalkoxylated carbon atoms.

The polyhydroxy fatty acid amide surfactants suitable for use in the present compositions include those having the structural formula R2CONR1Z in which: R1 is H, hydrocarbyl group of 1 to 4 carbon atoms, 2-hydroxy ethyl, 2-hydroxy propyl , ethoxy, propoxy, or a mixture thereof; R2 is a hydrocarbyl of 5 to 31 carbon atoms, which may be straight chain; and Z is a polyhydroxy hydrocarbyl having a linear hydrocarbyl chain with at least three hydroxyls directly connected to the chain, or an alkoxylated derivative (preferably ethoxylated or propoxylated) thereof. Z can be derived from a reducing sugar in a reductive amination reaction; such as a glycityl portion. Suitable non-ionic alkyl polysaccharide surfactants, particularly for use in the present compositions include those described in U.S. Patent No. 4,565,647, Filling, issued January 21, 1986. These surfactants include a hydrophobic group containing from about 6 to about 30 carbon atoms and a polysaccharide, for example, a polyglycoside, hydrophilic group containing from about 1.3 to about 10 units of saccharide. Any reducing saccharide containing five or six carbon atoms for example, glucose galactose and portions of galactosyl can be substituted for the glucosyl portions can be used. (Optionally, the hydrophobic group is attached at positions 2-, 3-, 4-, etc. thus giving a glucose or galactose as opposed to a glycoside or galactoside). The inter-saccharide linkages can be, for example, between position 1 of the additional saccharide units and positions 2-, 3-, 4- and / or 6 in the preceding saccharide units. Suitable fatty acid amide surfactants for use in the present compositions include those having the formula: R6CON (R7) 2 wherein R6 is an alkyl group containing from 7 to 21 carbon atoms and each R7 is independently hydrogen, alkyl of 1 to 4 carbon atoms, hydroxyalkyl of 1 to 4 carbon atoms, or (C2H40) xH, wherein x is in the range of 1 to 3. The treatise Nonionic surfactants, edited by Schick, MJ, Vol. 1 of the Surfactant Science Series, Marcel Dekker, Inc., New York, 1983, is an excellent reference on the wide variety of nonionic compounds generally employed in the practice of the present invention. A typical list of non-ionic classes, and species of these surfactants, is given in U.S. Patent No. 13,929,678 issued to Laughlin and Heuring on December 30, 1975. Additional examples are given in "Active Surface Agents and Detergents" ( Vol. I and II by Schwartz, Perry and Berch). Semi-Polar Non-ionic Surfactants The semi-polar type of non-ionic surface active agents is another class of nonionic surfactant useful in the compositions of the present invention. Generally, semi-polar nonionics are high foamers and foam stabilizers, which may limit their application in CIP systems. However, in the compositional modalities of this invention designed for high foaming cleaning methodology, semi-polar non-ionics would have immediate utility. Semi-polar nonionic surfactants include amine oxides, phosphine oxides, sulfoxides and their alkoxylated derivatives. The amine oxides are tertiary amine oxides corresponding to the general formula:
wherein the arrow is a conventional representation of a semi-polar junction; and R1, R2 and R3 can be aliphatic, aromatic, heterocyclic, alicyclic or combinations thereof. Generally, for amine oxides of detergent interest, R is an alkyl radical of from about 8 to about 24 carbon atoms; R2 and R3 are alkyl or hydroxyalkyl of 1 to 3 carbon atoms or a mixture thereof; R2 and R3 may be linked together, for example, through an oxygen or nitrogen atom, to form a ring structure; R 4 is an alkaline or hydroxyalkylene group containing 2 to 3 carbon atoms; and n ranges from 0 to about 20. Useful water-soluble amine oxide surfactants are selected from alkyl di- (lower alkyl) amine coconut or tallow oxides, the specific examples of which are oxides of dodecyl dimethylamine, tridecyl dimethylamine oxide, tetradecyl dimethylamine oxide, pentadecyl dimethylamine oxide, hexadecyl dimethylamine oxide, heptadecyl dimethylamine oxide, octadecyl dimethylamine oxide, dodecyl dipropylamine oxide, tetradecyl dibutylamine oxide, octadecyl dibutylamine oxide, bis (2-hydroxyethyl) dodecylamine oxide, bis (2-hydroxyethyl) -3-dodecoxy-1-hydroxypropylamine oxide, dimethyl- (2-hydroxydecyl) amine oxide, 3,6,9-trioctadecyldimethylamine oxide and 3-dodecoxy-2-hydroxypropyl di- ( 2-hydroxyethyl) amine. Useful semi-polar nonionic surfactants also include water-soluble phosphine oxides having the following structure:
wherein the arrow is a conventional representation of a semi-polar junction; and R1 is an alkyl, alkenyl or hydroxyalkyl portion ranging from 10 to about 24 carbon atoms in chain length; and R2 and R3 are each alkyl portions selected separately from alkyl or hydroxyalkyl groups containing from 1 to 3 carbon atoms. Examples of useful phosphine oxides include dimethyldecylphosphine oxide, dimethyltetradecylphosphine oxide, methylethyltetradecylphosphine oxide, dimethylhexadecylphosphine oxide, diethyl-2-hydroxyocydodecylphosphine oxide, bis (2-hydroxyethyl) dodecylphosphine oxide, and bis (hydroxymethyl) tetradecylphosphine oxide. The semi-polar nonionic surfactants useful herein also include the water soluble sulfoxide compounds having the structure:
wherein the arrow is a conventional representation of a semi-polar junction; and R1 is an alkyl or hydroxyalkyl portion from about 8 to about 28 carbon atoms, from 0 to about 5 ether linkages and from 0 to about 2 hydroxyl substituents; and R2 is an alkyl portion consisting of alkyl and hydroxyalkyl groups having from 1 to 3 carbon atoms.
Useful examples of these surfoxides include dodecyl methyl sulfoxide; 3-hydroxytridecylmethyl sulfoxide; and 3-hydroxy-4-dodecoxib useful methyl sulfoxide. Preferred semi-polar nonionic surfactants for the compositions of the invention include dimethylamine oxides, such as lauryl dimethylamine oxide, myristyl dimethylamine oxide, cetyl dimethylamine oxide, combinations thereof and the like. Silicone Surfactants The silicone surfactant may include a modified dialkyl, for example, a dimethyl polysiloxane. The hydrophobic polysiloxane group can be modified with one or more pendant hydrophilic polyalkylene oxide group or groups. Such surfactants can provide low surface tension, high wetting, high spray, defoaming and excellent stain removal. The silicone surfactants of the invention include a polydialkyl siloxane, for example, a polydimethyl siloxane to which polyether groups, typically polyalkylene oxide, have been grafted, through a hydrosilation reaction. The process results in a pendant alkyl copolymer (AP type), in which the polyalkylene oxide groups are attached along the siloxane structure by a series of hydrolytically stable Si-C bonds. These non-ionic polydialkyl siloxane substituted products have the following generic formula:
R3Si-0- (R2SiO) x (R2SiO) y-SiR3 wherein PE represents a non-ionic group, for example, -CH2 (CH2) P- 0- (EO) m (PO) nZ, with EO representing oxide of ethylene, PO representing propylene oxide, x is a number ranging from about 0 to about 100, m, n and p are numbers ranging from about 0 to about 50, m + n > 1 and Z represents hydrogen or R wherein each R independently represents a straight or branched lower alkyl (1-6 carbon atoms). Such surfactants have a molecular weight (Mn) of about 500 to 20,000. Other nonionic silicone surfactants have the formula:
| (C2H40) ¿7 (C3H6O) z, R
wherein x represents a number ranging from about 0 to about 100, and represents a number ranging from about 1 to about 100, a and b represent numbers that fluctuate independently from about 0 to about 60, a + b > 1, and each R is independently H or a straight or branched lower alkyl (1-6 carbon atoms). A second class of nonionic silicone surfactants is an alkoxy with blocked ends (type AEB) that are less preferred because Si-O- bonding offers limited resistance to hydrolysis under neutral or slightly alkaline conditions, but breaks rapidly in acidic environments. Suitable surfactants are sold under the trademark SILWET®, the trademark TEGOPREN® or under the trademark ABIL® B. A useful surfactant, SILWET® L77, has the formula: CH3Si-0 (CH3) Si (R1) 0-S (CH3) 3 wherein R = -CH2CH2CH2-0- [CH2CH2CH20] 2CH3; wherein z is from 4 to 16, preferably from 4 to 12, more preferably from 7 to 9. Other useful surfactants include TEGOPREN 5840®, ABIL B-8843® and ABIL B-8863®. Ammonium surfactants Useful also in the present invention are the surface active substances which are classified as anionic because the charge in the hydrophobe is negative; or surfactants in which the hydrophobic section of the molecule carries no charge unless the pH rises to neutral or above (e.g., carboxylic acids). The carboxylate, sulfonate, sulfate and phosphate are the polar (hydrophilic) solubilization groups found in ammonium surfactants. Of the cations (against ions) associated with these polar groups, sodium, lithium and potassium impart solubility in water; the ammonium and substituted ammonium ions provide solubility in both water and oil; and calcium, barium and magnesium promote solubility in oil. The anionics are excellent detergent or cleaning surfactants and are, therefore, favored additions for heavy duty detergent compositions. Generally, however, anionics have high foam profiles that limit their use alone or at high concentration levels in cleaning systems such as CIP circuits that require strict foam control. In addition, the surface active anionic compounds can impart special chemical or physical properties different from that of detergent in the composition. Anionics can be used as gelling agents or as part of a gelation or thickening system. The anionics are excellent stabilizers and can be used to control the hydrotropic effect and haze point. Most of the high volume commercial anionic surfactants can be subdivided into five main chemical classes and additional sub-groups, which are described in the "Encyclopedia of Surfactants", Cosmetics & Toiletries, Vol. 104 (2) 71-86 (1989). The first class includes acylamino acids (and salts), such as acylglutamates, acyl peptides, sarcosinates (e.g., N-acyl sarcosinates), taurates (e.g., N-acyl taurates and fatty acid amides of methyl tauride), and the similar ones. The second class includes carboxylic acids (and salts), such as alkanoic acids (and alkanoates), esters of carboxylic acids (for example, alkyl succinates), carboxylic acid esters and the like. The fourth class includes sulfonic acids (and salts), such as isethionates (e.g., acyl isethionates), alkylaryl sulfonates, alkyl sulfonates, sulfosuccinates (e.g., monoesters and sulfosuccinate diesters), and the like. The fifth class includes sulfuric acid esters (and salts), such as alkyl ether sulfonates, alkyl sulfonates and the like. Although each of these classes of ammonium surfactants can be employed in the present compositions, it should be noted that certain of these ammonium surfactants may be incompatible with the enzymes. For example, acyl-amino acids and salts may be incompatible with proteolytic enzymes due to their peptide structure. Suitable sulfate anionic surfactants for use in the present compositions include alkyl, linear and branched, primary and secondary sulfates, alkyl ethoxy sulfates, fatty oleyl glycerol sulphates, alkylphenol ether sulphates, ethylene oxide sulfates, acyl sulphates 5 to 17 carbon atoms) -N- (alkyl of 1 to 4 carbon atoms) and -N- (hydroxyalkyl of 1 to 2 carbon atoms) glucamine and sulfates of alkyl polysaccharides such as the alkyl polyglycoside sulphates (the compounds non-sulfated nonionics described herein). Examples of suitable synthetic water-soluble anionic detergent compounds include the ammonium and substituted ammonium salts (such as mono-, di- and triethanolamine) and alkali metal salts (such as sodium, lithium and potassium) of the mononuclear aromatic sulfonates which contain from about 5 to about 18 carbon atoms in the alkyl group in a straight or branched chain, for example, the alkylbenzene sulfonate salts or alkyl toluene, xylene, eumeno and phenol sulfonates; alkyl naphthalene sulfonates, diamyl naphthalene sulfonates and dinonyl naphthalene sulfonates and alkoxylated derivatives. The carboxylate anionic surfactants suitable for use in the present compositions include the alkyl ethoxy carboxylates, the alkyl polyethoxy polycarboxylate surfactants and the soaps (eg, alkyl carboxyls). Secondary soap surfactants (eg, alkyl carboxyl surfactants) useful in the present compositions include those which contain a carboxy unit attached to a secondary carbon. The secondary carbon can be in a ring structure, for example as in p-octyl benzoic acid, or as in alkyl-substituted cyclohexyl carboxylates. Secondary soap surfactants typically do not contain ether bonds, nor ester bonds nor hydroxide groups. In addition, they typically lack nitrogen atoms in the main group (amphiphilic portion). Suitable secondary soap surfactants typically contain 11 to 13 carbon atoms in total, although more carbon atoms (eg, up to 16) may be present. Other anionic detergents suitable for use in the present compositions include olefin sulfonates, such as long chain alkene sulfonates, long chain hydroxyalkane sulfonates or mixtures of alkenesulfonates and hydroxyalkane sulfonates. Also included are alkyl sulfonates, alkyl poly (ethyleneoxy) ether sulfonates and poly (ethyleneoxy) aromatic sulfonates such as sulfonates or condensation products of ethylene oxide and nonylphenol (usually having from 1 to 6 oxyethylene groups per molecule). Also suitable are resin acids and hydrogenated resin acids, such as Greek resin or fish, and hydrogenated resin acids and resin acids present in or derived from tallow oil. The salts in particular will be selected suitably depending on the particular formulation and the needs therein. Additional examples of suitable anionic surfactants are given in "Surface Active Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch). A variety of such surfactants are also generally described in U.S. Patent No. 3,929,678, issued December 30, 1975 to Laughlin et al. In column 23, line 58 to column 29 line 23. In one embodiment, the present composition includes sulfonates or substituted sulfonates of alkyl or alkylaryl and sulfonated products. In certain embodiments, the present composition includes linear alkane sulfonates, linear alkyl benzene sulfonates, alpha-olefin sulfonates, alkyl sulfates, secondary alkane sulfates or sulphonates or sulfosuccinates. Cationic surfactants Substances with surface activity are classified as cationic if the charge on the hydrotrope portion of the molecule is positive. Surfactants in which the hydrotrope carries no charge unless the pH is lowered to near neutral or less, but which are cationic then (eg, alkylamines), are also included in this group. In theory, cationic surfactants can be synthesized from any combination of elements containing an "onium" structure RnX + Y- and could include other compounds besides nitrogen (ammonium) such as phosphorus (phosphonium) and sulfur (sulfonium). In practice, the field of the cationic surfactant is dominated by nitrogen-containing compounds, probably because the synthesis routes for cationic nitrogen are simple and correct and give high yields of the product, which makes them less expensive. Cationic surfactants preferably include, more preferably refer to, compounds that contain at least one long chain hydrophobic carbon group and at least one positively charged nitrogen. The long chain carbon group can be attached directly to the nitrogen atom by simple substitution; or more preferably indirectly by a bridging group or functional groups in the so-called alkylamines and interrupted amido amines. Such functional groups can make the molecule more hydrophilic and / or more dispersible in water, more easily solubilized in water by mixtures of co-surfactants and / or water-soluble. For increased water solubility, additional primary, secondary or tertiary amino groups may be introduced or the amino nitrogen may be quaternized with low molecular weight alkyl groups. In addition, the nitrogen may be a part of the straight or branched chain portion of varying degrees of saturation or of a saturated or unsaturated heterocyclic ring. In addition, I 03 cationic surfactants may contain complex bonds having more than one cationic nitrogen atom. The surfactant compounds classified as amine, amphoteric and zuiterion oxides are themselves typically cationic in solutions of near neutral pH or acid and may overlap surfactant classifications. The polyoxyethylated cationic surfactants generally behave as nonionic surfactants in alkaline solution and as cationic surfactants in acid solution. The simplest cationic amines, the amine salts and the quaternary ammonium compounds can be represented schematically as follows:
R 'R R "_ R-N R-N-H + X" R-N-R'X
wherein, R represents a long alkyl chain, R ', R "and R'" can be long alkyl chains or smaller alkyl or aryl groups or hydrogen and X represents an anion. Amine salts and quaternary ammonium compounds may be useful due to their high degree of water solubility. The majority of high volume commercial cationic surfactants can be subdivided into four major classes and additional subgroups known to those skilled in the art and described in the "Encyclopedia of Surfactants," Cosmetics & Toiletries, Vol. 104 (2) 86-96 (1989). The first class includes alkylamines and their salts. The second class includes alkyl imidazolines. The third class includes ethoxylated amines. The fourth class includes quaternary, such as alkylbenzyldimethylammonium salts, alkyl benzene salts, heterocyclic ammonium salts, tetraalkyl ammonium salts and the like. Cationic surfactants are known to have a variety of properties that may be beneficial in the present compositions. These desirable properties may include detergency in compositions at or below neutral pH. Antimicrobial efficacy, thickening or gelling in cooperation with other agents, and the like. Cationic surfactants useful in the compositions of the present invention include those having the formula R1mR2xYLZ wherein each R is an organic group containing a straight or branched alkyl or alkenyl group optionally substituted with up to three phenyl or hydroxy groups and optionally interrupted by up to four of the following structures:
or an isomer or mixtures of these structures and containing from about 8 to 22 carbon atom. The R groups can additionally contain up to 12 ethoxy groups. m is a number from 1 to 3. Preferably no more than one group R in a molecule has 16 or more carbon atoms when m is 2 or more than 12 carbon atoms when m is 3. Each R 2 is an alkyl group or hydroxyalkyl containing from 1 to 4 carbon atoms or a benzyl group with not more than one R2 in a molecule that is benzyl, and x is a number from 0 to 11, preferably from 0 to 6. The remainder of any positions of atoms of carbon in the group Y is filled by hydrogens. And it can be a group that includes, but is not limited to:
(C2H40) -N- (C2H40) p = about 1 to 12
- s-
or a mixture of them. Preferably, L is 1 or 2, with the groups Y which are separated by a selected portion of analogs of R and R2 (preferably alkylene or alkenylene) having from 1 to about 22 carbon atoms and two free single carbon ligations when L is 2. Z is a water-soluble anion, such as a halide, sulfate, methylsulfate, hydroxide or nitrate group, with chloride, bromide, iodide, sulfate or methyl sulfate anions being particularly preferred in a number to give electrical neutrality of the cationic component. Amphoteric surfactants Amphoteric surfactants, or ampholytic surfactants, contain both an acidic and basic group and an organic hydrophobic group. These ionic entities may be any of the anionic or cationic groups described herein for other types of surfactants.
A basic nitrogen and an acidic carboxylate group are the typical functional groups employed as the basic hydrophilic and acidic groups. In some surfactants, sulfonate, sulfate, phosphonate or phosphate provide the negative charge. Amphoteric surfactants can be broadly described as derivatives of secondary and tertiary aliphatic amines, in which the aliphatic radical can be straight or branched chain and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains a anionic group for solubilization in water, for example, carboxy, sulfo, sulfate, phosphate or phosphono. Amphoteric surfactants are subdivided into two main classes known to those of skill in the art and described in the "Encyclopedia of Surfactants", Cosmetics &; Toiletries, Vol. 104 (2) 69-71 (1989). The first class includes acyl / dialkyl ethylenediamine derivatives (eg, 2-alkyl hydroxyethyl imidazoline derivatives) and their salts. The second class includes N-alkylamino acids and their salts. Some amphoteric surfactants can be designed to accommodate both classes. Amphoteric surfactants can be synthesized by methods known to those skilled in the art. For example, 2-alkyl hydroxyethyl imidazoline is synthesized by condensation and ring closure of a long chain carboxylic acid (or derivative) with dialkyl ethylenediamine. Commercial amphoteric surfactants are derived by subsequent hydrolysis and ring opening of the imidazoline ring by alkylation - for example with chloroacetic acid or ethyl acetate. During the alkylation, one or two carboxy-alkyl groups react to form a tertiary amino and an ether linkage with different alkylating agents giving different tertiary amines. The long chain iodazole derivatives which have application in the present invention generally have the general formula: (MONO) ACETATE (DI) PROPIONATE SULFONATO ANFOTERICO
Neutral pH - zuiterion where R is a hydrophobic acyclic group containing from about 8 to 18 carbon atoms and M is a cation that will neutralize the charge of the anion, usually sodium. Amphoteric commercially important imidazoline derivatives which may be employed in the present compositions include for example: cocoanfopropionate, cocoanfocarboxypropionate, cocoanfoglycinate, cocoanfocarboxyglycinate, cocoanopropyl sulfonate and cocoanfocarboxypropionic acid. Preferred amphocarboxylic acids are produced from fatty imidazolines in which the functionality of the dicarboxylic acid of the amphodicarboxylic acid is diacetic acid and / or dipropionic acid. The carboxymethylated compounds (glycinates) described hereinbefore are often called betaines. Betaines are a special class of amphotericins discussed herein below in the section entitled Zuiterionic Surfactants. The long-chain N-alkyl amino acids are easily prepared by the reaction of RNH2, wherein R = straight chain or branched alkyl of 8 to 18 carbon atoms, fatty amines with halogenated carboxylic acids. Alkylation of the primary amino groups of an amino acid leads to secondary and tertiary amines. The alkyl substituents may have additional amino groups that provide more than one nitrogen receiving center. The most commercial N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N (2-carboxyethyl) alanine. Examples of commercial M-alkyl amino acid ampholytes having application in this invention include alkyl beta-amino dipropionates, RN (C2H4COOM) 2 and RNHC2H COOM. In these, R is preferably a hydrophobic acyclic group containing from about 8 to about 18 carbon atoms, and M is a cation that neutralizes the charge of the anion. Preferred amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acid. Most preferred of these coconut-derived surfactants include as part of their structure a portion of ethylenediamine, an alkanolamide portion, an amino acid portion, preferably glycine, or a combination thereof; and an aliphatic substituent from about 8 to 18 (preferably 12) carbon atoms. Tai surfactant can also be considered an alkyl amphipicarboxylic acid. Disodium cocoampropionate is one of the most preferred amphoteric surfactants and is commercially available under the trademark Miranol ™ FBS from Rhodia, Inc., Cranbury, N.J. Another amphoteric surfactant derived from the preferred coconut with the chemical name cocoanthus disodium diacetate is sold under the trademark Miranol ™ C2M-SF also from Rhodia, Inc., Cranbury, N.J. A typical listing of amphoteric and species classes of these surfactants is given in U.S. Patent No. 3,929,678 issued to Laughlin and Heuring on December 30, 1975. Additional examples are given in "Active Surface Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch). Zwitterionic Surfactants Zwitterionic surfactants can be thought of as a subset of amphoteric surfactants. Zwitterionic surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium or tertiary sulfonium compounds. Typically, a zwitterionic surfactant includes a positively charged quaternary ammonium or, in some cases, a sulfonium or phosphonium ion; a negatively charged carboxyl group; and an alkyl group. Zwitterionics generally contain cationic and ammonium groups which ionize to an almost equal degree in the isoelectric region of the molecule and which can develop a strong "internal salt" attraction between positive and negative charge centers. Examples of such synthetic zwitterionic surfactants include derivatives of quaternary ammonium compounds, aliphatic phosphonium and sulfonium, in which the aliphatic radicals can be straight or branched chain and wherein one of the aliphatic substituents contains from 8 to 18 carbon atoms and one contains an anionic group of solubilization in water, for example, carboxy , sulfonate, sulfate, phosphate or phosphonate. The betaine and sultaine surfactants are exemplary zwitterionic surfactants for use herein. A general formula for these compounds is:
wherein R 1 contains an alkyl, alkenyl or hydroxyalkyl radical of from 8 to 18 carbon atoms having from 0 to 10 portions of ethylene oxide and from 0 to 1 portion of glyceryl; And it is selected from the group consisting of nitrogen, phosphorus and sulfur atoms; R2 is an alkyl or monohydroxyalkyl group containing one to three carbon atoms; x is 1 when Y is a sulfur atom and 2 when Y is a nitrogen or phosphorus atom, R3 is an alkylene or hydroxyalkylene or hydroxyalkylene of 1 to 4 carbon atoms and Z is a radical selected from the group consisting of carboxylate, sulfonate, sulfate, phosphonate and phosphate. Examples of zwitterionic surfactants having the structures listed above include: 4- [N, N-di (2-hydroxyethyl) -N-octadecylammonium] -butane-1-carboxylate; 5- [S-3-hydroxypropyl-S-hexa-d eci Is u Ifon io] -3-h idroxypen tan o-1-sulfate; 3- [P, P-diethyl-P-3,6,9-trioxa-tetracosanphosphon io] -2-h idroxpropan-1-phosphate; 3- [N, N-dipropyl-N-3-dodecoxy-2-hydroxypropyl-ammonium] -propran-1-phosphonate; 3- (N, N-dimethyl-N-hexadecylammonium) -prophan-1 -su Ifon ato; 3- (N, N-dimethyI-N-hexadecyl-ammonium) -2-hydroxy-propran-1 -su Ifon ato; 4- [N, N-di (2 (2-hydroxyethyl) -N- (2-idroxidodecyl) ammonium] -b uta n-1-carboxylate; 3- [S-ethyl-S- (3-dodecoxy) 2-hydroxypropyl) sulfonium] -propran-1-phosphate; 3- [P, P-dimethyl-P-dodecyl-phosphonium] -propran-1-phosphonate; and S [N, N-di (3-hydroxypropyl) -N -hexadecylammonium] -2-hydroxy-pentan-1-sulfate The alkyl groups contained in said detergent surfactants may be straight or branched and saturated or unsaturated The zwitterionic surfactant suitable for use in the present compositions includes a betaine of the general structure:
CH2-CO2"
These surfactant betaines do not typically exhibit strong cationic or anionic characters at extreme pH's or show reduced solubility in water in their isoelectric range. Unlike "external" quaternary ammonium salts, betaines are compatible with anionics. Examples of suitable betaines include coconut acylamidopropyl dimethyl betaine; hexadecyldimethyl betaine; acylamidopropyl betaine of 12 to 14 carbon atoms; acylamidohexadhexyl betaine of 8 to 14 carbon atoms; 4-acyl of 4 to 16 carbon atoms methylamidodiethylammonium-1-carboxybutane; acyl 16 to 18 carbon atoms amidodimethyl betaine; acyl of 12 to 16 carbon atoms amidopentandiethyl betaine; and acyl of 12 to 16 carbon atoms methylamidodimethyl betaine. Sultains useful in the present invention include those compounds having the formula (R (R1) 2 N + R2SOs ", in which R is a hydrocarbyl group of 6 to 18 carbon atoms, each R1 is typically independently alkyl of 1 to 4 carbon atoms. to 3 carbon atoms, for example, methyl, and R2 is a hydrocarbyl group of 1 to 6 carbon atoms, for example, an alkylene or hydroxyalkylene group of 1 to 3 carbon atoms, a listing of typical zwitterionic classes, and species of these surfactants are given in U.S. Patent No. 3,929,678 issued to Laughlin and Heuring on December 30, 1975. Additional examples are given in "Surface Active Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch.) Surfactant Compositions The surfactants described hereinbefore may be used alone or in combination in the practice and utility of the present invention, In particular, nonionics and anionics may be used in combination. Amphoteric and zwitterionic, nonionic, cationic, semi-polar surfactants can be used in combination with non-ionic or anionic surfactants. The above examples are merely specific illustrations of the numerous surfactants that may find application within the scope of this invention. The above organic surfactant compounds can be formulated in any of several forms of the commercially desirable composition of this invention which has described its utility. Said compositions include washing treatments for soiled surfaces in concentrated form which, when supplied or dissolved in water, properly diluted by a proportioning device and delivered to the target surfaces as a solution, gel or foam will provide cleaning. Said cleaning treatments consisting of a product; or that involve a system of two products where proportions of each are used. Said product is typically a liquid concentrate or emulsion. Hydrotrope A hydrotropic agent is often employed in the formulation to maintain a pure or aqueous single-phase composition. Such an agent can be used in the present invention. Hydrotropia is a property that refers to the ability of materials to improve the solubility or miscibility of a substance in liquid phases in which the substance tends to be insoluble. The substances that provide hydrotropia are called hydrotropes and are used in relatively lower concentrations than the materials to be solubilized. A hydrotrope modifies a formulation to increase the solubility of an insoluble substance or creates mixed miscellar or miscellar structures that result in a stable suspension of the insoluble substance. In this invention, hydrotropes are most useful for maintaining the components of the formulas in a uniform solution both during manufacture and when they are dispensed at the location of use. The hydrotrope solubilizer can maintain a one-phase solution having the components evenly distributed throughout the composition in an aqueous or non-aqueous form. Preferred hydrotrope solubilizers are used from about 0.1 to about 30% by weight and include, for example, small molecule ammonium surfactants and semi-polar nonionic surfactants. The most preferred range of hydrotrope solubilizers is from about 1 to about 20% by weight. Hydrotrope materials are relatively well known for exhibiting hydrotropic properties in a broad spectrum of chemical molecule types. Hydrotropes generally include ether compounds, alcohol compounds, anionic surfactants, cationic surfactants and other materials. A major hydrotrope solubilizer for use in this invention includes an amine oxide material. The small molecule anionic surfactants include aromatic or sulphonated sulfonic acid hydrotropes such as benzene sulphonic acid or substituted naphthalene sulphonic acid of 1 to 5 carbon atoms. Examples of such a hydrotrope are xylene sulfonic acid or naphthalene sulphonic acid or salts thereof. The semi-polar type of the nonionic surface active agents includes amine oxide hydrotropes such as tertiary amine oxides corresponding to the general formula:
G i- (OR ¾-N ¾
where n is from 0 to 25, the arrow is a conventional representation of a semi-polar ligature; and R ,, R2 and R3 can be aliphatic, aromatic, heterocyclic, alicyclic or combinations thereof. Generally, for amine oxides of detergent interest, R1 is an aliphatic or alkyl radical, linear or branched, from about 8 to about 24 carbon atoms; R2 and R3 are selected from the group consisting of alkyl or hydroxyalkyl of 1 to 3 carbon atoms and mixtures thereof; R 4 is an alkylene or hydroxyalkylene group containing 2 to 3 carbon atoms; and n ranges from 0 to about 20. Useful water-soluble amine oxide hydrotropes are selected from alkyl di- (lower alkyl) amine oxides, specific examples of which are isoalkyl oxide of 10 to 14 carbon atoms dimethylamine, (iso-dodecyl) dimethylamine-Barlox 12i oxide, n-decyldimethylamine oxide, dodecyldimethylamine oxide, tridecyldimethiamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylamine oxide, dodecyldipropylamine, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis (2-hydroxyethyl) dodecylamine oxide, bis (2-hydroxyethyl) -3-dodecoxy-hydroxypropylamine oxide, d-oxide methyl- (2-hydroxydecyl) amine and 3,6,9-trioctadecyldimethylamine oxide.

Enzymes The present cleaning osition can include one or more enzymes, which can provide a desirable activity for the removal of spots based on protein, based on carbohydrates, or based on triglycerides of substrates; for cleaning, staining and pre-wetting. Although not limiting to the present invention, enzymes suitable for the present cleaning ositions can act by degrading or altering one or more types of soil debris found on a surface or textile thereby removing dirt or making dirt more removed by a surfactant or other onent of the cleaning osition. Both the degradation and the alteration of the dirt residues can improve detergency by reducing the physicochemical forces that agglutinate the dirt to the surface or the textile to be cleaned, that is, the dirt bes more soluble in water. For example, one or more proteases are used to cleave lex protein macromolecular structures present in the dirt residues in simpler short chain molecules which, by themselves, are more readily released from the surfaces, or otherwise more easily removed by detergent solutions containing said proteases. Suitable enzymes include a protease, an amylase, a lipase, a gluconase, a cellulase, a peroxidase or a mixture thereof of any suitable origin, such as of vegetable, animal, bacterial, fungal or yeast origin. Preferred selections are influenced by factors such as activity, optimum pH and / or stability, thermostability and stability to active detergents, abrasives and the like. In this regard, bacterial or mycotic enzymes, such as bacterial amylases and proteases, and fungal cellulases are preferred. Preferably, the enzyme is a protease, a lipase, an amylase or a combination thereof. As used herein, "detergent enzyme" means an enzyme that has a cleaning, stain or otherwise beneficial effect as a component of a composition for laundry, textiles, dishwashers, on-site cleaning, drains, floors, carpets , medical or dental instruments, meat cutting tools, hard surfaces, personal care or the like. Suitable detergent enzymes include a hydrolase, such as a protease, an amylase, a lipase or a combination thereof. The enzymes are normally incorporated into a composition according to the invention in a quantity sufficient to give an effective cleaning during a washing or pre-wetting process. An effective amount for cleaning refers to an amount that produces a clean, sanitary and, preferably, corrosion-free appearance to the cleaned material. An effective amount for cleaning can also refer to an amount that produces an improved effect of cleaning, stain removal, dirt removal, bleaching, deodorization or freshness on the substrates. Typically, such a cleaning effect can be achieved with amounts of enzyme from about 0.1% to about 3% by weight, preferably from about 1% to about 3% by weight, of the cleaning composition. Higher active levels may also be desirable in highly concentrated cleaning formulations. Commercial enzymes, such as alkaline proteases, can be obtained in liquid or dried form, sold as aqueous solutions of raw material or in purified, assorted, processed and compound forms and include from about 2% to about 80% by weight, of active enzyme generally in combination with stabilizers, buffers, co-factors, impurities and inert vehicles. The actual content of active enzyme depends on the manufacturing method and is not critical, assuming that the composition has the desired enzymatic activity. The particular enzyme selected for use in the process and products of this invention depends on the conditions of the ultimate utility, including the physical form of the product, the pH of use, the temperature of use and the types of soil to be digested, degraded or altered. The enzyme can be selected to provide optimal activity and stability for any given set of utility conditions. The compositions of the present invention preferably include at least one protease. It has further been found that the composition of the invention, surprisingly, not only stabilizes the protease over a shelf life substantially extended, but also significantly increases the activity of the protease for protein digestion and the increased removal of proteins. dirt. In addition, the increased activity of the protease occurs in the presence of one or more additional enzymes, such as amylase, cellulase, lipase, peroxidase, endoglucanase and mixtures thereof, preferably lipase or amylase enzymes. The enzyme can be selected for the type of dirt as a target for the cleaning composition or present at the site or the surface to be cleaned. Although not limited to the present invention, it is believed that the amylase may be advantageous for cleaning dirt containing starch, such as potato, pasta, flour, baby food, sauce, chocolate or the like. Although not limiting to the present invention, it is believed that the protease may be advantageous for cleaning dirt containing proteins, such as blood, skin flakes, mucus, fat, food (e.g., eggs, milk, spinach, meat residues, tomato sauce) or the like. While not limiting the present invention, it is believed that the lipase may be advantageous for cleaning dirt containing grease, oil, or wax, such as grease, oil or animal or vegetable wax (eg, salad dressing, butter, butter, etc.). pork, chocolate, lipstick). Although not limited to the present invention, it is believed that the cellulase can be advantageous for cleaning cellulose-containing or cellulose-containing dirt that serves as attachment points for other dirt.

Other conventional sequestrants such as bisulfate, nitrate, chloride, hydrogen peroxide sources such as sodium perborate tetrahydrate, sodium perborate monohydrate and sodium percarbonate, as well as phosphate, condensed phosphate, acetate, can be used if desired. benzoate, citrate, formate, lactate, malate, tartrate, salicylate, etc., and mixtures thereof. In general, since the function of the chlorine sequestrant can be performed by ingredients listed separately under better recognized functions, there is no requirement to add a separate chlorine sequestrant unless a compound that performs that function to the desired degree is absent from an embodiment containing enzyme of the invention; even then, the sequestrant is added only for optimal results. In addition, the formulator will exercise a normal chemical skill to avoid the use of any sequestrant or enzyme stabilizer that is unacceptably incompatible, as formulated, with other reactive ingredients. In relation to the use of the ammonium salts, such salts can be simply mixed with the composition; but they tend to absorb water and / or release ammonia during storage.

Compositions of Use The compositions and methods of the invention are suitable for removing complex organic or greasy dirt and inorganic dirt from a variety of substrates. The compositions of the invention can be pure (ie, without diluent such as an aqueous diluent) or can be diluted with water or other liquid medium to form an aqueous degreasing solution. In addition, the degreasing compositions of the invention can be used as an additive with other cleaning compositions formulated to clean substrates. The cleaning compositions of the invention can be used for organic and inorganic dirt that removes grease as an additive to remove grease for a material! of formulated cleaning. Such cleaning materials are common in the industry and include hard surface cleaners, laundry detergents, general purpose cleaners for use in domestic and institutional applications, floor cleaners, glass cleaners, etc. The compositions of the invention are used as an additive by adding them to a conventional cleaning formulation of from about 0.1 to about 20% by weight of the composition of the invention. The materials of this invention, even when diluted heavily in aqueous solution alone or in a formulation, such as a glass cleaner, a hard surface cleaner, a general purpose cleaner or a laundry detergent, can provide a grease removal exceptional that is as effective as the concentrated material. The compositions of the invention can be used with full force (pure, ie in the absence of an aqueous diluent). The compositions of the invention are applied directly to organic or greasy dirt typically on a hard surface such as glass, metal, composite, wood, etc. surfaces. The compositions combined with the organic or greasy dirt, tend to reduce any interface of dirt / hard surface that binds and reduces the tackiness of the complex dirt and reduces the viscosity of the dirt material, resulting in a relative ease of physical removal. A composition of use can include any of the amounts by weight percent of ingredients listed above divided by the amount of dilution and can be expressed as% by weight or ppm. In particular, the amounts listed above for boric acid salt and the microbial component or spores are for concentrated compositions. For example, a composition of use may include any of the amounts in% by weight listed above independently divided by 10, 20, 30, 40, 50, 60, 70, 80, 90,100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000 or 10,000. In one embodiment, the dilution is by a factor of 56 g of concentrate for 3,875 liters of use composition. Foaming In a modality, the present composition can be mixed with diluent to form a use composition that is used in a skimmer. The foaming application can be carried out, for example, by using a foam application device such as a tank skimmer or a wall mounted skimmer, for example, using a foaming nozzle or a trigger sprinkler. The application of foaming can be carried out by placing the composition of use in a pressure vessel for 58 liter foam application, such as a 58 liter stainless steel pressure vessel with mixing propellant. The foaming composition can then be dispensed through a trigger sprinkler for foaming. A wall-mounted frother can use air to expel the foam from a tank or line. In one embodiment, compressed air can be injected into the mixture, then applied to the object through a foam application device such as a tank skimmer or a wall mounted skimmer. Mechanical foaming heads that can be used according to the invention to provide foam generation include those heads that cause the air and the foaming composition to mix and form a foamed composition. That is, the mechanical head for foaming causes the air and the foaming composition to mix in a mixing chamber and then pass through an opening to produce a foam. Suitable foaming mechanical heads that can be used in accordance with the invention include those available from Airspray International, Inc., of Pompano Beach, Florida, and Zeller Plastik, a division of Crown Cork and Seal Co. The appropriate mechanical heads for Foamed materials that can be used in accordance with the invention are described, for example, in U.S. Patent No. D-452,822; U.S. Patent No. D-452,653; U.S. Patent No. D-456,260; and U.S. Patent No. 6,053,364. Mechanical foaming heads that can be used in accordance with the invention include those heads that are actuated or that attempt to be actuated by applying pressure from a finger to a trigger that causes the foaming composition and air to mix and produce a foam. That is, the pressure of a person's finger can cause the trigger to be depressed thereby removing the foaming composition and the air towards the head and causing the foaming composition and the air to mix and produce a foam. Methods Employing the Present Compositions In one embodiment, the cleaning composition is applied directly to a large dirt deposit, allowing it to soften and promote the removal of dirt. Once the composition has been allowed to increase the dirt removal capacity, the cleaner and the removed dirt can be easily removed with a rinsing step. In one embodiment, the method omits rinsing. That is, the present composition can be applied and the surface is not rinsed. The compositions of the invention which include a nonionic surfactant, a nonionic silicone surfactant, an ammonium surfactant and a hydrotrope can be contacted directly with the hard surface for the removal of organic, oily or greasy dirt. Depending on the substrate, such a composition may additionally include a chelating agent having a final formulation that includes a nonionic surfactant, and a nonionic silicone surfactant, an anionic surfactant, a hydrotrope solubilizer and a chelating agent. These compositions can be used on substantially non-corrosive surfaces, such as plastics, wood, coated wood, stainless steels, composite materials, fabrics, cement and others. In one embodiment, the present method includes a method for cleaning a hard surface. The method may include applying to the surface a cleaning composition that includes spores or bacteria; a borate salt; from about 0.5 to about 35% by weight of nonionic surfactant; and from about 0.1 to about 35% by weight of silicone surfactant. The method may include application of the composition to a floor, drainage or a combination thereof. In one embodiment, the present method includes a method for cleaning a floor. Such a method may include increasing the coefficient of friction of the floor. Such a method may include cleaning the cementation of a mosaic floor. The cleaning of the cement can include allowing it to show more of its natural color. The method includes applying a stabilized spore composition according to the present invention to the floor.

In one embodiment, the present method can include effectively removing from the floor covering (eg, mosaic) a film that is slippery when wet. The method may include cleaning the floor covering and increasing its coefficient of friction. In one embodiment, the present method for cleaning a hard surface may include applying the present composition to a surface of a bath, such as a wall, a floor or accessories. The surface of the bathroom can be a wall or surface of the shower. The surface of the bathroom can be a wall with mosaics.

In one embodiment, the present composition includes a thickener or humectant, which may assist in retention of the composition on a horizontal or vertical surface. In one embodiment, the present method can include the application of the present composition to a surface having grease or oil therein. Such surfaces include a floor, a parking lot, a department hall, a garage floor, a parking ramp floor and the like. In one embodiment, the present method includes spraying a surface with the present composition. In one embodiment, the present method includes applying the stabilized microbial composition to a surface and keeping the surface moist for an extended period, such as one to two hours to about eight to about 16 hours. Maintaining the wet surface can be done by repeated application of the composition, such as by spraying. Maintaining the wet surface can be done by contacting the surface with a sponge, wet mop with the composition for an extended period. Maintaining the wet surface can be done by applying a persistent stable microbial composition. A persistent stable microbial composition can remain on the surface and keep the surface moist. For example, a thickened composition and certain foaming compositions may remain on the surface and keep the surface moist. The extended presence of the present composition can provide a faster cleaning compared to a composition that dries or evaporates. The present invention can be better understood with reference to the following examples. These examples are intended to be representative of specific embodiments of the invention and are not intended to limit the scope of the invention. EXAMPLES Example 1 - Microbial Preparations Stabilized with Borate Salts The compositions according to the present invention were shown to stabilize the microbial preparations, specifically a spore composition that digests fat. Materials and Methods This experiment evaluated the aerobic plaque counts produced from various cleaning compositions including bacterial spores, with or without aging of the compositions. Those compositions that include viable spores produced colonies of bacteria with lipolytic activity that resulted in dark areas in coated growth medium. The dark zones resulted from the production of free fatty acids. The controls included spores or bacteria suspended in water and a conventional bacterial cleaning composition. The test method was a normal protocol of
"Lipolytic Microorganisms", Compendium of Methods for the Microbiological Food Examination, third edition, 1992, p. 183. Briefly, plaques of Iipolitic agar were prepared. The plates were inoculated with the test bacterial suspensions and allowed to dry. Nutrient agar was emptied on the inoculated surface. The plates were incubated at room temperature to allow the growth of bacteria and inspected for the appearance of lipolytic colonies. The lipolytic colonies were identified by a dark blue surrounding area. The following compositions were made and tested in this example:

Conclusions Amine borate salts stabilize the spores of bacteria that digest fat and the bacteria themselves. Increased stability was observed for concentrated compositions including salts of amine borate and mixture of spores. For example, a six-day sample of formula 5 (without borate) lost approximately one log of bacterial activity. A sample of unknown age lost approximately two logs of bacterial activity. Unexpectedly, the amine borate salts, which may have limited solubility, were soluble in compositions with silicone surfactants. Example 2 - Borate Salt Compositions Including Microbial Preparations Stabilized with Polyol The compositions according to the present invention and including both borate salt and polyol were shown to stabilize the microbial preparations, specifically a composition of spores that digest fat. Materials and Methods Compositions were made according to the general formulas listed in Example 1, but with varying concentrations of borate counter (for example, aicanoiamine) and polyol (for example, propylene glycol). The stability of the compositions was determined by measuring lipolytic activity at various times after the composition was made. The compositions generally contained 2% by weight of spore mixture. Each composition was diluted to 2% by weight to test for bacterial growth, which was done as described in Example 1. The following compositions were made and tested in this example.

Conclusions Only minor reductions in bacterial growth occurred as the compositions aged for up to eight weeks.
The most significant reductions in bacterial growth were observed after 12 weeks of aging. For example, bacterial growth was reduced by more than or equal to one log for composition numbers 13, 14, 16, 17, 18, 19 and 20. That means that composition numbers 11, 12, and 15 exhibited the greatest stabilization after 12 weeks of aging. These results confirm that borate salts (eg, alkanolamine borate salts) stabilize the spore mixture. Interestingly, each of the compositions lacking polyol showed a production of more than one log. This indicates that the polyol contributes to the stabilization of the spore mixture. Interestingly, the present compositions stabilized the spore mixture still at a pH above 9.5, a pH of 10, and still at a pH of 10.5. For example, composition 12 stabilized the spore mixture for up to 16 weeks at a pH of about 10. EXAMPLE 3 - Compositions with Borate Salt Stabilizing Microbial Preparations at a Basic pH The compositions according to the present invention were demonstrated and they include both borate salt and polyol stabilize the microbial preparations, specifically a composition of spores that digest fat, in a wide range of basic pH. Materials and Methods Compositions were made according to the general formulas listed in Example 1, but with variable pH. The stability of the compositions was determined by measuring the lipolytic activity at various times after the composition was made. The compositions generally contained 2% by weight of spore mixture. Each composition was diluted to 2% by weight to test for bacterial growth, which was done as described in Example 1. The following compositions were made and tested in this example.
All quantities in% by weight.

Example 5 - Stabilized Microbial Compositions Increase Slip Resistance of Floors Compositions according to the present invention and including borate salt, polyol and lipase showed that they are effective to significantly increase the slip resistance of a tile floor. Materials and Methods A use solution was applied that included composition 33 (14.5 g / L or 16% concentrate) each day to a tile floor, specifically a floor of terrazzo mosaics, without rinsing. Dry and wet skid resistance measurements were taken over a period of six weeks in kitchens of five restaurants. The six weeks included two weeks for base measurements and four weeks or measurements after application of the composition 33. Before cleaning with the present composition (for example, during the base period and before), the floor was cleaned daily with a conventional floor cleaning composition commercially available. Slip resistance was measured as a coefficient of friction (COF) using an English XL Variable Incidence Tribometer in accordance with ASTM F1679-02. The protocol was as follows. 15 quarry mosaics were selected in each restaurant kitchen. In the main passage corridors and areas of interest (for example, near the frying pans) each fifth mosaic was selected. The same 15 tiles were evaluated in each restaurant for COF each week. The COF of each tile was measured four times, once in each of four directions separated by 90 °. Each tile measured as dry as wet. The 60 measurements under each condition were averaged for each restaurant, and the results were averaged for the five restaurants. Results Figure 1 illustrates the results obtained weekly for the COF (slip resistance) for the 15 tiles in each of the five restaurants. The dry mosaic COF improved from an average base value of 0.60 to 0.81 through the four week trial period. The wet mosaic COF improved from a base average value of 0.38 to 0.56 through the four week trial period. Each of these increases is significant with a confidence level that exceeds 99%. Conclusion The compositions according to the present invention significantly increase the friction coefficients for slippery surfaces, such as floors in restaurant kitchens. Example 6 - Stabilized Microbial Compositions Clean Encemented The compositions according to the present invention and including borate salt, polyol and lipase were shown to be effective in cleaning the cement between the tiles. Materials and Methods A dilution of use of composition 33 (14.5 g / L or 1.6% concentrate) was applied to the tile floor, specifically a quarry tile floor, without rinsing, as described in Example 5. The mosaic it was photographed before and after the application of the present composition. Results The photographs of Figures 2A and 2B illustrate that the present composition cleaned the cement in a quarry tile floor in a restaurant kitchen. Figure 2A illustrates the floor before the application of the present composition. Figure 2B illustrates the floor after application of the present composition. Figure 3 illustrates a portion of a floor cleaned with a conventional cleaning composition (left) and a portion cleaned with composition 33. The composition 33 cleaned the cement, the conventional composition did not. Conclusions The present compositions cleanse the mosaics more effectively than conventional compositions. Example 7 - Stabilized Microbial Compositions Clean Floors Compositions according to the present invention and including borate salt, polyol and spores proved to be effective for cleaning floors. Materials and Methods A dilution of use of composition 34 (14.5 g / L or 1.6% concentrate) was applied to a mosaic floor, specifically a floor of quarry mosaics, without rinsing. The floor was evaluated before and after the application of the present composition.
Results Composition 34 cleaned the floor. Conclusions The present compositions clean floors more effectively than conventional compositions.
