These patent applications are directed to liquid non-aqueous non-ionic laundry detergent compositions.

The detergency of synthetic nonionic surfactant detergents in detergent compositions can be increased by the addition of builders. Sodium tripolyphosphate is one of the preferred builders.

However, the use of sodium polyphosphates in dry powder detergents has several disadvantages, such as the tendency of polyphosphates to hydrolyze to less valuable poly- and ortho-phosphates.

In addition, the laundry detergent poly-f! X4 salt content has been compromised by the undesirable high phosphate content of surface waters.

Increased content of V4 salts in surface water contributes towards algae blooms, thereby shifting the biological equilibrium of the water in the opposite direction.
It has been discovered that

Recently enacted government regulations are aimed at reducing the amount of polyphosphates present in laundry detergents, thereby
In jurisdictions where polyphosphate R salts have been a problem, there has been a shift toward requiring laundry detergents to be completely free of polyphosphate builders.

Liquid detergents are often found to be more convenient to use than dry powder or granular products, and therefore have been found to be substantially more convenient for consumer use. They are readily meterable, dissolve quickly in washing water, can be easily applied as a concentrate or warm dispersion to contaminated areas on clothing to be washed, and are non-clumping and usually Small storage space is required. Furthermore, during the formulation of liquid detergents, granular detergent products, which always deteriorate during drying operations,
Materials that are often desirable for use in N may also be incorporated. Although they have many advantages over monolithic or particulate solid products, liquid detergents often have some inherent disadvantages that must also be overcome to create an acceptable commercial detergent product. For example, some products of this type separate on storage, some separate on cooling, and do not readily redisperse. In some cases,
The product viscosity changes and is either too thick to pour or thickens and becomes watery. Some clear products produce cloudiness, while others gel when purchased with 11I.

In addition to problems with sedimentation or phase separation, non-aqueous liquid detergents (based on liquid non-ionic surfactants) have been shown to contain bacteria that gel when the non-ionic agent is added to cold water. Worry about shortcomings. Is this a European-style home automatic washing machine? +'
This is a particularly important problem when using a single dose of diethylene glycol monobutyl ether, in which case the user places the WashjR detergent composition into the machine's dispensing metering device (eg, dispensing shelf). During operation of the machine, the detergent in the dispenser is subjected to a flow of cold water that transfers the detergent into the body of washing solution.

Particularly during the winter months when the detergent composition and water supplied to the dispenser are particularly cold, detergent viscosity increases significantly and gels form. As a result, some of the composition does not flow completely out of the dispensing device during machine operation, and composition deposits build up during repeated washes and leaks, making it difficult for the user to actually flush the dispensing device with hot water. You will need to wash it off.

The phenomenon of gelation also occurs whenever it is desired to carry out laundering using cold water, as is recommended for certain synthetic delicate fabrics that can shrink in hot or hot water. This could be a problem.

The tendency of concentrated detergent compositions to gel during storage is exacerbated by storing the composition in an unheated storage area or by shipping the composition in an unheated transport vehicle during the winter months.

Partial solutions to the gelation problem include, for example, low-handling alkanols such as ethyl alcohol (U.S. Pat. No. 3.'1
53.380), alkali metal formates and adipates (US Pat. No. 4.368.147), certain viscosity-controlling solvents and gelling agents such as hexylene glycol, polyethylene glycol, etc. have been exploited by diluting liquid non-ionic agents and by structural modification and optimization of non-ionic adjuvants. As an example of nonionic adjuvant structural modification, one particularly successful result was achieved by acidifying the hydroxy moiety end groups of the nonionic molecule. h at the end of the nonionic agent
Advantages of incorporating rubonic acid include prevention of gelation upon dilution, lowering of nonionic adjuvant pour point, and formation of anionic surfactant when neutralized in N solution. Structural optimization for non-ionic properties is based on the chain length of the hydrophobic-lipophilic component and the alkylene oxide of the hydrophilic component (e.g.
The focus is on the number and composition of oxides (e.g. ethylene oxide). For example, it has been discovered that C13 aliphatic alcohols 1-oxylated with 8 moles of ethylene oxide exhibit only a limited tendency toward gel formation.

However, improvements in both the stability and gelation prevention of phosphate-free liquid fabric treatment compositions are desired.

According to the present invention, highly concentrated low phosphate, more specifically polyphosphate builder-free, non-aqueous liquid detergent compositions contain alkaline in liquid non-ionic surfactant detergents. It is made by dispersing metal lower polycarboxylic acid builder salts.

Acid-terminated nonionic surfactants can be added to improve the viscosity properties of the composition.

To further improve the viscosity and storage properties of the composition,
Viscosity improvers and antigelling agents such as alkylene glycol monoalkyl ethers, and anti-settling agents such as aluminum stearate and phosphate esters can be added to the composition.

In a preferred embodiment of the invention, the detergent composition includes an acid-terminated nonionic Bamboo W surfactant, an alkylene glycol or noalkyl ether, and an antisettling agent.

Disinfectants or bleaching agents and activators thereof can be added to improve the bleaching and cleaning properties of the composition.

In one embodiment of the invention, the builder component of the composition is ground to a particle size of less than 100 microns, preferably less than 10 microns, to stabilize the builder component suspension in a liquid non-ionic surfactant detergent. Roughly improve your sexuality.

In addition, crust formation inhibitors, antifoaming agents, optical brighteners, enzymes,
Other ingredients such as anti-redeposition agents, perfumes and dyes can be added to the composition.

Washing machines currently manufactured for home use are officially capable of washing up to 100 degrees Celsius. ? Operates at temperature. Washing) Use 18.5 gallons (70 ρ) of water during the overfilling.

- About 250 g of powdered detergent per υ wash is normally used.

In accordance with the present invention, where a highly concentrated liquid detergent is used, typically only 100 g (77 cc) of liquid detergent composition is required to wash a full load of dirty laundry.

In particular, the detergent fills a container with a non-aqueous liquid laundry detergent composition consisting of a liquid non-ionic surfactant that is minimally but predominately free of polyphosphate building blocks and transfers the composition from the container to a laundry water bath. A method of dispensing is provided, in which dispensing is carried out by directing a stream of unheated water onto the composition such that the composition is carried by the stream into the bath.

, ion 1 The nonionic synthetic organic detergent used in the practice of this invention may be any of a wide variety of well known compounds.

As is well known, nonionic synthetic organic detergents are characterized by the presence of organic hydrophilic groups such as organic hydrophobic groups, and are typically organic aliphatic or alkyl aromatic hydrophobic compounds and ethylene oxide (hydrophilic). produced by which condensation. In practice, any hydrophobic compound having a carboxy, hydroxy, amide, or amino group with a free water attached to the nitrogen is combined with ethylene oxynide or its polyhydric product, polyethylene glycol. can be used to form non-ionic detergents. The length of the hydrophilic or polyoxyethylene chain can be easily adjusted to achieve the desired balance between hydrophobicity and hydrophilic groups.

Representative suitable nonionic surfactants are U.S. Pat.
6,812 and 3.630.929.

Typically, non-ionic detergents are polylower alkoxylated lipophilic substances, in which case the desired hydrophilic-lipophilic balance is 1
It is obtained from the addition of hydrophilic polylower alkoxy groups to the lipophilic component. Preferred types of nonionic detergents used are those in which the alkanol has from 9 to 18 carbon atoms and the number of moles of the lower alkylene oxylide (having 2 or 3 carbon atoms) is from 3 to 12. It is a poly(lower alkyl)oxylated higher alkanol. Among these substances, there are 9 to 11 higher alkanols or 12 to 1
Preference is given to using higher aliphatic alcohols of 5 carbon atoms and containing 5 to 8 or 5 to 9 lower alkoxy groups per mole.

Preferably, the lower alkoxy is ethoxy, but in some cases it may be desirable to mix it with propoxy, the latter often in a small proportion (up to 50%) if present.

Examples of such compounds are those in which the alkanol is of 12 to 15 carbon atoms and contains about 7 ethylene oxinide groups per mole, such as Neodol 25-7 and Neodol 23- (i, 5,
They are products of the Shell Chemical Company.

The former is a condensation product of a mixture of higher aliphatic alcohols having an average number of carbon atoms of about 12 to 15 and about 7 moles of ethylene oxynide; It is a mixture of ethylene oxide (the number of J oid V is on average 6.5).

Higher alcohols are primary alkanols.

Other examples of detergents of this type are Tergitol 15-8-7
and Turgidol 15-3-9, both linear secondary alcohol ethoxylates manufactured by Union Carbide. The former is a mixed ethoxylation product of a linear secondary alkanol of 11 or 615 carbon atoms with 7T-nyl ethylene oxide, and the latter is a similar but reacted product of 9 moles of ethylene oxide.

Also useful in this invention as nonionic detergent ingredients are polymeric nonionic agents such as Neodol 45-11, which are similar ethylene oxylide condensation products of higher aliphatic alcohols; Higher aliphatic alcohols have 14 to 15 carbon atoms,
The number of ethylene oxide per mole is approximately 11.

Such products are also made by the Shell Chemical Company.

Useful non-ionic agents are represented by the commercially well-known class of non-ionic agents sold under the trademark Plurafac. Pullluff? Tsuku is a reaction product of a higher straight chain alcohol with a mixture of ethylene oxide and propylene oxide, contains a mixed chain of ethylene oxide and propylene oxide, and terminates in a hydroxyl group. Examples include Product A (6 moles of ethylene oxide and 3 moles of propylene quaternary:
Cl3-015 aliphatic alcohol condensed with side),
Product B (7 moles of propylene oxide and 4
Product C (C13-Cl3 aliphatic alcohol condensed with 5 moles of propylene oxide and 10 moles of ethylene oxide)).

Another group of liquid non-ionic agents are shell chemicals.
It is commercially available under the trade name Dopanol from the Company. Dopanol 91-5 is an ethoxylated C9-C11 fatty alcohol with an average of 5 moles of ethylene oxide, and Dopanol 25-7 is an ethoxylated C12-015 fatty alcohol with an average of 7 moles of ethylene oxide per mole of fatty alcohol. It is a family alcohol.

In order to achieve the best balance between hydrophilic and lipophilic components in the preferred polylower alkoxylated higher alkanol, the lower alkoxy number is usually 40% to 100% of the number of carbon atoms in the higher alcohol, Preferably from 40 to 60%, the nonionic detergent preferably contains at least 50% of the preferred polylower alkoxy higher alkanol of the type.

High molecular weight alkanols and various other normally solid non-ionic detergents and surfactants can cause gelation of liquid detergents and therefore limit the amount of gelation omitted in the present compositions. It is preferable.

However, a small percentage of them may be used for purification purposes, etc. Regarding both preferred non-ionic detergents and less preferred non-ionic detergents,
The alkyl group present in the chain is generally straight chain, provided that the next carbon after the terminal carbon of the straight chain or the next carbon 2
Branching at separate carbons and away from the ethoxy chain is permitted provided that such branched alkyls are of no more than three carbons. Usually the proportion of carbon atoms in such branched forms is small, hardly exceeding 20% of the total carbon atom content of the alkyl. Similarly, although straight chain alkyls terminally attached to the ethylene oxide chain are considered to be highly preferred and provide the best combination of legality, biodegradability and non-gelling properties, the ethylene oxide in the chain Intermediate or secondary conjugates to may also occur.

It is usually a small percentage of such alkyl, generally 2
Although it is less than 0%41, the above-mentioned Targhi 1--
There may be more, as in the case of Le. Further, when propylene oxide is present in the lower alkylene oxide chain, it usually accounts for 20% or less, preferably 10% or less.

a greater proportion of non-terminal alkoxylated alkanols,
When a propylene oxide-containing poly-lower alkoxylated alkanol and a detergent with a less lipophilic-lipophilic balance than those mentioned above are used in place of the preferred, 11 ionic agent mentioned above, the product to be IF is the preferred composition. However, the use of the viscosity and gelation regulating compounds of the present invention also applies to detergents based on non-ionic agents which do not have any good affectability, stability, viscosity properties and non-gelling properties. can improve the properties of In some cases, such as when high molecular weight polylower alkoxylated higher alcohols are often used for their detergent properties, the proportions are determined to obtain the desired legality and still be non-gelling and of the desired viscosity. Obtaining the product is adjusted or limited according to routine experimentation. It has also been discovered that there is little need to utilize high molecular weight valve ionic agents for their washability, since the preferred nonionic agents described herein do not gel at low temperatures. It is possible to achieve the desired viscosity in liquid detergents.

This is because it is possible.

Another useful group of nonionic surfactants are the nonionic agents available from British Petroleum in the "Surfactant T" series. This Refactor T nonionic agent is obtained by ethoxylation of a secondary C13 aliphatic alcohol with a narrow ethylene oxide distribution. Surfactant T5 receives an average of 5 moles of ethylene oxide, surfactant T7 receives an average of 7 moles of ethylene oxide, and surfactant T
9 has an average of 9 moles of ethylene oxide.

Surfactant T12 has an average of 12 moles of ethylene oxide per mole of secondary C13 aliphatic alcohol.

In the compositions of the present invention, preferred nonionic surfactants include ethylene oxide in the range of about 7 to 9 moles + Il.
1 of relatively narrow amounts of Cl3-015 secondary aliphatic alcohol, J3, and a C9-C11 aliphatic alcohol ethoxylated with about 5-6 moles of ethylene oxide.

Mixtures of two or more than two liquid nonionic surfactants can be used, and in some cases can be obtained by the use of such mixtures.

The viscous and gelling properties of r-terminated, ionic 1' liquid detergent compositions can be improved by including in the composition an effective amount of an acid-terminated liquid nonionic surfactant. Acid-terminated nonionic surfactants are nonionic surfactants modified to convert the hydroxyl groups of kIIII to free carboxyl groups, such as esters of nonionic surfactants and polycarboxylic acids or anhydrides.・[Or consists of a partial ester.

The present invention includes an organic alkali metal lower polycarboxylic acid builder salt as an essential part of the composition.

Preferred organic builder salts consist of lower polycarboxylic acids, such as alkali metal salts of 2 to 4 carboxyl groups. Preferred lower polycarboxylate salts of sodium and potassium are citrate and tartrate.

Most preferred is the sodium citrate Pli salt, especially trisodium citrate. L-nonodium and disodium tartrate salts can also be used. When [nonodium and trina]-lium citrates are used, sodium silicate, e.g., disodium silicate, is added as a supplementary builder salt to adjust the pH to approximately the same level obtained when using trina]-lium citric acid. It is preferable to do so.

Mononotrium and disodium tartrate can also be used.

Alkali metal lower polycarboxylate salts are particularly good builder salts, and because of their high calcium and magnesium binding capacity, crust formation caused by the formation of otherwise insoluble calcium and magnesium salts is avoided. This is because it prevents

Other organic builders that can be used are polymers and copolymers of polyacrylic acid and polymaleic anhydride and their alkali metal salts. More particularly, such builder salts may consist of a copolymer of approximately equimolar reaction products of methacrylic acid and maleic anhydride, which have been completely neutralized to form their sodium salts. can. The builder is commercially available under the trade name Tukaran CP5. This builder helps prevent crusting even when used in small amounts.

Examples of organic alkaline sequestering builder salts which can be used together with alkali metal lower polycarboxylic acid builder salts or in admixture with other organic and inorganic builders include alkali metal, ammonium or substituted builder salts. Ammonium aminopolycarboxylate salts, such as sodium and potassium ethylenediaminetetraacetate ([0■^), nitrilotriacetic acid (N

1J゛, Binoru U'' Non-ion + IL! The inclusion of a low molecular weight amphiphilic compound, which functions as a trace control agent and an anti-gelling agent for the ll1i surfactant, in a detergent composition substantially improves the storage properties of the composition. Change your clothes. These amphiphilic compounds can be considered similar in chemical structure to ethoxylated and/or propoxylated aliphatic alcohol liquid nonionic surfactants, but with relatively short hydrocarbon chain lengths. (C to C8) and a low content of 1 brune oxide (approximately 2 to 6 ebrene oxide groups per molecule).

Suitable amphiphilic compounds can be represented by the general formula %J: where R is a C2-C8 alkyl group and n is a number on average from about 1 to 6.

The acidic organophosphorus compounds are, for example, partial esters of phosphoric acid and alcohols, such as alkanols with novel properties, having more than 5 carbon atoms, for example 8 to 12 carbon atoms.

A specific example is a partial ester of phosphoric acid and a C16-C18 alkanol (Mbiphos 5632, manufactured by Marchon), which is composed of about 35% monoester and 65% diester.

The inclusion of very small amounts of acidic organophosphorus compounds makes the suspension significantly more stable against settling on standing, yet remains injectable, while for low concentrations of stabilizer, e.g., about 1% or less, Its plastic viscosity generally decreases.

Further improvements in the stability properties and sedimentation properties of the compositions can be achieved by adding small effective amounts of higher fatty acid aluminum salts to the compositions.

The aluminum salt stabilizer is a jointly pending patent application S of the common assignee.
．． N. No. 725,455 (Registered April 22, 1985), the disclosure of which is incorporated herein by reference.

The preferred higher fatty acids have about 8 to about 22 carbon atoms, more preferably about 10 to 20 carbon atoms, and particularly preferably about 12 to 18 carbon atoms. The aliphatic group may be saturated or unsaturated, linear or branched. As with nonionic surfactants, mixtures of fatty acids may also be used, such as those derived from natural sources such as tallow acid, coconut fatty acid, and the like.

Examples of fatty acids from which aluminum salt stabilizers are formed include decanoic acid, dodecanoic acid, parcimitic acid, myristic acid, stearic acid, oleic acid, eicosanoic acid, tallow fatty acid, coconut fatty acid, mixtures thereof, and the like. Aluminum salts of these acids are commonly commercially available and are preferably used in the form of triacids, such as aluminum stearate, such as aluminum tristearate Δρ (01,113,Coo) 3 3. One monoacid is aluminum heptanostearate 11 (OH)
2 (C1□H3,C00) and a di6 base such as aluminum distearate 1(OH) (C17H35CO
O)2, and mixtures of two or three of mono-, di- and tri-acid aluminum salts can also be used. but,
tricate is at least 3 of aluminum fatty acid jn total stone
Most preferably it consists of 0%, preferably at least 50%, particularly preferably at least 10%.

Aluminum salts, as mentioned above, are commercially available and can be readily prepared, for example, by saponifying a fatty acid such as animal fat, stearin M<E, and subsequently treating the resulting soap with alum, alumina, or the like.

Although Applicants do not wish to be bound by any particular theory of the manner in which aluminum salts function to prevent settling of suspended particles, it is believed that aluminum salts increase wetting of solid surfaces by nonionic surfactants. It is considered to be 1. This increased wetting therefore causes suspended particles to remain in suspension more easily.

Only a very small amount of aluminum jn stabilizer is required to achieve a significant improvement in physical stability.

Besides its action as a physical stabilizer, aluminum
Cum salts, more than other physical stabilizers, are characterized by the fact that they are nonionic in nature, are compatible with nonionic surfactant components, and do not interfere with the overall detergency of the composition. It exhibits some defoaming effect, can function to enhance the activity of fabric softeners, and has the added advantage of providing better relaxation times for suspensions.

Marginal high surface area inorganic thickeners or dispersants can be included, such as other highly bulky inorganic support materials disclosed in US Pat. However, compositions that form peroxyacids in V baths (e.g., compositions containing peracid compounds and activators therefor) must be substantially free of such compounds and other silica salts. is preferred; for example, silica and 11M salts have been found to promote undesirable decomposition of peroxyacids.

In embodiments of the invention, the stability of the bilgoux salt in the composition during storage and the stability of the dispersibility of the composition in water is
The improvement is achieved by reducing the particle size of the solid builder by milling to below 100 microns, preferably below 40 microns, more preferably below 10 microns. Solid builders are typically supplied in particle sizes of approximately 100°200 or 1400 microns. The nonionic liquid surfactant phase may be mixed with the solid builder before or after the milling operation. I can do it.

Preferably no more than about 10%, especially no more than about 5%, of the total suspended particles have particles larger than 10 microns. Compositions in which the dispersed particles are of such small particle size have improved stability against segregation or settling during storage. The addition of acid-terminated nonionic surfactant compounds aids in the dispersibility of the dispersion without reducing dispersion stability against sedimentation.

In the milling operation, the proportion of solid components is sufficiently large that the solid particles are in contact with each other and are not substantially shielded from each other by the nonionic surfactant liquid (e.g.
preferably at least about 40%, such as about 50%).

After this milling step, any remaining liquid non-ionic surfactant liquid can be added to the milling formulation. Mills using grinding balls (ball mills) or similar movable grinding members have given very good results. For example, a laboratory batch attritor with 8 m+ diameter steatite grinding balls may be used.
