are described.

The invention relates to detergent compositions, in particular liquid, textile-softening and antistatic, 10

especially builder-containing compositions with a content of surfactant, builder (preferably) for the surfactant, Bentonite and isostearamide with a higher aliphatic substitution on nitrogen as antistatic agents in an aqueous medium. the

The invention also relates to a method of washing and 15

Drying of laundry, in which one obtains a soft laundry with no or only little electrostatic charge, also when dried in a conventional tumble dryer.

20 containing builder and synthetic organic surfactant

Compositions are the detergent of choice today

for washing dirty laundry. Such compositions have been found to be extremely effective for washing Textiles made of synthetic and / or natural fiber materials proved, both with oily and 25th

Soils containing protein or clay, these three types of soils being those found on household laundry occur most frequently and which can be regarded as reasonably representative of soiling, which is more common

dirty laundry. With the replacement of soap by 30

synthetic organic tensxde in detergents went the The softening effect of soap (mostly as insoluble soap deposited on the textile fibers of the laundry) is lost, so that, especially in the presence of certain inorganic builder salts, the laundry often becomes rough and stiff or plump

and feels uncomfortable. It has been known for years that bentonite has been added to detergent compositions

Based on anionic surfactants, it can help to soften the laundry and this is how detergents can be produced that can be accepted by the consumer.

Although liquid detergent compositions have been known for years, heavy duty detergents are only in the liquid state popular for a relatively short time. Such formulations are sometimes, especially when they are contain suspended solids, thickened to prevent these components from settling on storage. Gel forming Bentonite such as Western or Wyoming bentonite has thickening properties and is also a fabric softener.

With the advent of synthetic polymeric fibers, clothing and other laundry items made from these fibers as well Mixing the same with natural fibers such as cotton / polyester mixtures and with increasing use of automatic clothes dryers, which are mostly of the drum dryer type (tumblers), it has been found that dry laundry often accumulates electrostatic charges, causing them to stick together in an uncomfortable way, which interferes with the normal handling and folding of the laundry for storage. We have known for years that

cationic compounds such as quaternary ammonium salts, e.g.

Di (higher) -alkyldi (lower) -alkylammonium halides capable are to act as antistatic agents (antistatic agents), i.e. to reduce the static charges on textiles and thus avoiding electrostatic sticking or sticking. Such halides would be used to soften laundry normally during a wash program in the rinse water and not in the detergent composition or in the wash water as they react chemically with anionic surfactants, which are the most commonly used surfactants in detergents are. This reaction, believed to be stronger in liquid detergents than with particulate products

would reduce the detergent composition's detergency reduce and could form undesirable reaction products that settle on the laundry to be washed and result in dirty or greasy stains. In recent years, cationic compounds such as the quaternary have been found Ammonium halides in detergent compositions containing builders, especially particulate detergent compositions built in, in which they are not appreciable with the anionic surfactants during storage, to a certain extent However, the extent to which they react in the wash water. It has been found that although these compositions are a Have an antistatic effect and reduce the static sticking of washed laundry, but that the cleaning power the detergent containing them is lower than that of the basic compositions without the antistatic.

In US SN 404 794 and the CIP, US SN 674 194 ^ the Use of isostearamides substituted on the nitrogen with primary alkyl as antistatic agents in detergent compositions

Tongues described and reported that these isostearamides do not significantly use anionic surfactants in the compositions or react in the wash water. It is also reported that the isostearamides described with Bentonite can combine and apply with particulate detergent compositions, while doing a wash water obtained, which has both fabric softening and antistatic properties, so that washed with it The laundry is soft and free from unacceptable static sticking. The present invention describes in detail liquid detergent compositions containing both bentonite and nitrogen-substituted isostearamide as Contain antistatic agents, the desired effects achieved thereby, including that the washed wash is sufficient is soft (especially towels made from woven fabrics or otherwise processed vegetable fibers, such as Cotton and terrycloth), little or no static

Gluing, better cleaning and no "quat spots" shows. before What is particularly noteworthy is the surprising improvement in the antistatic effect of that which is primarily aliphatic on nitrogen substituted isostearamide due to the presence of bentonite in the liquid built detergent composition (in the presence of an anionic surfactant). Additionally, it was found that there was neither one A reduction in foaming leads to a reduction in the effect of fluorescent brighteners when the inventive, anionic surfactant as well as bentonite and CISA-containing detergent compositions used, whereas when quaternary ammonium salts are used as antistatic agents, foam formation is obviously reduced due to the reaction of the quaternary salt with the anionic surfactant. There are also yellowing or the like Discoloration of the laundry by an antistatic agent as well as the reprecipitation of dirt are reduced in comparison with the Results obtained by using a quaternary

Ammonium halide used with an anionic surfactant because of its possible antistatic effects.

Δ It is the object of the invention to provide a fabric softening and antistatic liquid detergent composition as well as a softening and antistatic liquid To make the product available for the manufacture of the detergent.

To solve the problem, a fabric softening and

Antistatic liquid detergent composition proposed containing a detergent amount of a synthetic organic surfactant, a fabric softening amount of bentonite and an antistatic amount of higher aliphatic isostearamide contains as an antistatic in an aqueous medium. Usually the active cleansing component is the detergent composition described is an anionic

Surfactant (which react with a quaternary ammonium salt would) and the detergent a builder-containing composition that contains a builder such as sodium tripolyphosphate, Sodium carbonate, NTA or polyacetal carboxylate or other suitable builders or a mixture of these Includes builder. In a preferred liquid detergent composition, the isostearamide is dissolved, emulsified, or dispersed and the bentonite present as a finely divided dispersion, the particles of which are preferably smaller than Number 200 US sieve series, for example sizes from numbers 200 to 400, e.g. about number 325. The bentonite and / or the N-isostearamide can be added to the wash water before, after or together with the rest of the ingredients as desired the liquid detergent composition described are added.

That in the detergent compositions according to the invention applied anionic surfactant is usually sulfated and / or sulfonated lipophilic material with a Alkyl chain of 8 to 20, preferably 10 to 18 and particularly preferably 12 to 16 carbon atoms, the is preferably a particulate mixture of 2 kinds of these surfactants. Although various water-soluble salt-forming Cations to form the desired sulfated and sulfonated surfactants including ammonium and lower Alkanolamine (such as triethanolamine) and magnesium will normally be an alkali metal such as magnesium Sodium or potassium are used, with sodium being the preferred cation. Among the various anionic, for Surfactants useful in the practice of the invention are the linear higher alkylbenzenesulfonates with 10 to 18, preferably 12 to 16 and more preferably about 12 to 14 carbon atoms in the alkyl chain, e.g., dodecyl and Tridecyl most suitable, often with a fatty alcohol sulfate of a polyethoxylated higher fatty alcohol. That Alcohol ether sulfate usually comes from a higher,

linear (for example fatty) alcohol with 10 to 18, preferably 12 to 15 carbon atoms, the degree of ethoxylation usually 1 to 15 ethoxy groups per mole, preferably 2 to 10, particularly preferably 2 to 5, e.g. 3. Useful are also the monoglyceride sulfates, higher fatty alcohol sulfates, Paraffin sulfonates and olefin sulfonates, whereby in all these compounds contain the alkyl group 10 to 18 present Has carbon atoms. Some of these alkyl groups may be slightly branched (not preferred) provided they a carbon chain length in the ranges described

own.

Although the linear higher alkylbenzenesulfonates and the sulfated polyethoxylated alcohols higher than sodium salts are the anionic ones preferred according to the invention 5

Surfactants can be mixtures of these surfactants with other such sulfonates and sulfates containing other cations as well as mixtures of these surfactants with others, e.g. the fatty alcohol sulfates. In some cases are only relatively small proportions or smaller amounts of the linear alkylbenzenesulfonates and polyethoxylate sulfates present, or the anionic surfactant can be a mixture of other anionic surfactants of the types described. Various other anionic surfactants can also be used

as they are sufficiently known to the person skilled in the art and in 25

various publications are described, for example in McCutcheon's Detergents and Emulsifiers, 1969.

Although the invention is primarily anionic detergent compositions that have antistatic properties are the desired results reported herein also achievable with compositions containing other types of surfactants, often with the anionic surfactants, such as

nonionic and amphoteric surfactants. The mentioned 35

nonionic and amphoteric substances are usually

present only in small proportions, if at all, in general it is at most half as much as there are anionic surfactants present. Preferred nonionic Surfactants are the ethylene oxide condensation products of higher fatty alcohols, e.g. the condensation products of higher ones Fatty alcohols with 12 to 18 carbon atoms and 3 to 20 moles of ethylene oxide, preferably condensation products higher fatty alcohols with 12 to 15 carbon atoms and up to 15 moles of ethylene oxide.

The detergent is preferably built up with a surfactant builder so that it has increased detergency and as Heavy-duty detergent is suitable. Useful builders for the compositions of the invention are the polyphosphates

such as sodium tripolyphosphate and tetrasodium pyrophosphate, sodium carbonate, sodium bicarbonate, sodium sesquicarbonate _{, sodium silicate (Na 2 OrSiO 3} = 1, 6 to 3.0, preferably 1: 2.4), NTA, sodium citrate, sodium gluconate, borax, other borates, zeolites, polyacetal carboxylates and others for liquid

Laundry detergents are known to be useful builders. Often times, sodium silicates are left out because they are in liquid media Can react impermissibly with carbonate and zeolite builders as well as with bentonite and thereby undesirably thick or

coagulated products or precipitates arise. 25th

If zeolite builders are used, they generally correspond to the formula (Na ₉ O). (Al ₉ O-.) .W H ₉ O, where χ is, y is 0.8 to 1.2, preferably about 1, ζ 1.5 to 3.5, preferably 2 to 3 or about 2, and w

bxs 9, preferably 2.5 bxs 6. These zeolites are cation exchangers with an exchange capacity for calcium ions from about 200 to 400 or more milligram equivalents of calcium carbonate hardness per gram They are common hydrated to a moisture level of 5 to 30,

preferably 10 to 25%, e.g. about 20%. Zeolite A is preferred (X and Y are also useful) and type 4A zeolite

is most preferred. The particle sizes of the zeolites are usually 100 to 400 mesh (or sieve numbers), preferably 140 or 200 to 325 mesh, their outermost

However, particle sizes are in the submicron range. The various 5

which zeolites are extensively described by Donald W. Breck in "Zeolite Molecular Sieves" published in 1974 by John Wiley & Sons, particularly on pages 747-749.

Polyacetal carboxylates can be used according to US Pat. No. 4,144,226 and prepared by the process described there will. A typical such product has the formula

R ₁ - (CHO) _n - R ₂

where M is selected from the group consisting of alkali metal, ammonium, alkyl

groups with 1 to 4 carbon atoms, tetraalkylammonium and alkanolamine groups, which have 1 to 4 carbon atoms in their alkylene, η means at least 4 on average and R ₁ and R ₂ mean chemically stable groups which the polymer against rapid depolymerization in

stabilize alkaline solution. The polyacetal carboxylate is preferably one in which M is an alkali metal, e.g. Is sodium, η is 20 to 200, R. is

Although the preferred polyacetal carboxylates have been described, others may use them in whole or in part such polyacetal carboxylates or related organic builder salts may be substituted as they are in various Monsanto patents are described including

Methods of making the same and compositions in which they can be used. The Monsanto patents, particularly U.S. Pat. No. 4,144,226, can be used, provided that that they have the desired stabilizing properties

ten which allow the builders mentioned to be depolymerized in acidic media, what theirs Biodegradation in wastewater is facilitated, but its stability in alkaline media and in washing solutions is retained.

If the presence of phosphorus in the detergents is to be avoided, the polyphosphate builders can be omitted. In these cases it is preferred to use other, phosphate-free builders such as those mentioned here. Combinations of zeolite with polyacetal carboxylate represent a very

useful substitutes for the polyphosphate builders. Such combinations with N-alkyl isostearamides in

Detergent compositions (but without bentonite) have already been described in US Pat. No. 674,899. The sodium salts these builders are preferred but can be used in their place

The antistatic agent of choice for practicing the invention is N-cocoisostearamide. This antistatic is an amide that can be chemically formed from isostearic acid and cocoamine by the following condensation reaction:

• I, "

RCOH + R ¹ NH ₂ - »- RCNHR ¹ + H ₂ O

Isostearic acid, RC-OH. Is a saturated fatty acid of the formula C ₁₇ H ₃₅ COOH, a complex mixture of isomers, especially those with methyl side chains, which are mutually soluble

and are essentially inseparable. Although this 30

Acid is normally used for purposes similar to stearic or oleic acid, it is used for these materials Production of effective antistatic substances which are suitable for incorporation into the detergents according to the invention, far

think. Cocoamine is an aliphatic amine whose 35th

aliphatic group is derived from coconut oil. Other primary aliphatic amines, preferably higher alkyl amines

having 7 to 18 carbon atoms in the alkyl such as R ¹ NH ₂ , where R ^{1 is} such a higher alkyl, can also be used. Cocoamine, however, produces an N-alkyl isostearamide with the best properties for incorporation in detergents. His name is CISA.

Although CISA is the most preferred antistatic, others can also be aliphatic on nitrogen in accordance with the invention

substituted isostearamides can be used, such as those that 10

derive from primary amines having up to 20 carbon atoms, preferably 7 to 18 carbon atoms, wherein the aliphatic part of which can optionally be hydrogenated, provided that the amides are used for the stated purpose show sufficient antistatic effect. Some examples

for this are the N-alkyl isostearamides with 7 to 18 carbon atoms like the ones that differ from N-decylamine, and N-octylamine Derive N-tallowamine. However, CISA is recognized as the best N-alkyl isostearamide for its antistatic activity considered why when using other isostearamides this

are preferably used with CISA and the amount of other isostearamids is preferably less than that of CISA. In some cases the hydrogen atom of the Amide nitrogen must be replaced by suitable radicals such as lower alkyl, e.g. methyl, previously

assumes that you still achieve a desired antistatic effect. However, it has been found that the tertiary Isostearamides generally show little antistatic effect.

The bentonite used is preferably a Wyoming or Western bentonite with a swelling capacity of 3 to 15, preferably 7 to 15 ml / g. Its viscosity is 6% concentration in water usually in the range of 3 to 30, preferably 8 to 30 cps. Usable source bento-

Nites of this kind are sold under the trade name "Mineral Colloid" as industrial bentonites by the Benton Clay

Company, a subsidiary of Georgia Kaolin Co. sold. These materials were previously sold by this company as THIXO-JEL. It is selective mined and enriched bentonites. Most useful are those available as Mineral Colloid 101, etc., which correspond to those that were earlier than THIXO-JEL's No. 1, 2, 3 and 4 were sold. These materials have pH values (at a concentration of 6% in water) from 8 to 9.4, maximum free moisture contents of about 8% and specific gravity of about 2.6. The powder quality works 85% through a 200 mesh sieve (US sieve series). This bentonite is known as bentonite clay AEG 325 from American Colloid Co. sold the equivalent of essentially one

Sieve size of the number 325 possesses.
15th

Enriched Wyoming bentonite is included as part of the invention Detergents are preferred, but other bentonites are also useful, especially if they only have one make up a lower proportion of the bentonite used. It

it has been found that at least about 2%, preferably at least 4%, and most preferably 5% or more to about 8% water should initially be present in the bentonite before it is mixed with other bead components and with the mixed liquid medium for the liquid detergent

will. It was found that overdrying up to that Point at which the bentonite loses its "internal" moisture, the ability of the bentonite to be effective in water To hydrate medium, impair and the usefulness of the compositions according to the invention for textile

can greatly reduce plasticization.

The various auxiliaries that are used in the inventive Liquid detergents may be present, include coloring substances such as dyes and pigments, fragrances,

Enzymes, stabilizers, thickeners, solvents, dispersants, activators, fluorescent brighteners,

Bleaches, buffers, fungicides, germicides, foaming agents, Antifoam agents and substances that promote flowability. In the excipients, builders and fillers are also, if not mentioned in other classes, various additional components or impurities which are sometimes present in the ingredients of the compositions. For example, we know that often sodium carbonate and water with polyacetal carboxylate are present in Builder U, a product made according to the invention is used as a supplier of polyacetal carboxylate.

The amounts of the essential ingredients of the detergent compositions are chosen to be effective for the purposes intended. So that's synthetic organic surfactant or mixture present in the liquid detergent of the invention in a cleaning amount that Bentonite in a textile softening amount and the antistatic, higher aliphatic substituted isostearamide in an anti-static amount. If builder or a builder mixture is used, this is usually the case according to the invention if so, it is present in a buildable amount. The proportions of the liquid detergent are usually 3 to 25%, preferably 3 to

15% and particularly preferably 5 to 13% sodium (linear, 25th

higher) alkyl benzene sulfonate, e.g., about 9% sodium (linear) alkyl benzene sulfonate having 12 to 14 carbon atoms, 0.5 to 10% sodium (higher) fatty alcohol polyethoxy ether sulfate with up to 18 carbon atoms in the alcohol part and 1 to 15 moles Ethylene oxide per mole, preferably 1 to 5% sodium (higher, primary) alcohol polyethoxy ether sulfate with 12 to 15 Carbon atoms in the alcohol and 2 to 4 or 6 moles of ethylene oxide per mole, e.g. about 2%. The builder for the liquid laundry detergents, which can be a mix of builders, normally make up 5 to 40% of the composition and is often a combination of 5 to 25% sodium tripoly-

phosphate and 2 to 10% sodium carbonate, preferably often a combination of 8 to 14% sodium tripolyphosphate and 3 up to 7% sodium carbonate, for example about 11 or 4%. the Bentonite component is usually 3 to 20% of the liquid detergent composition, preferably 5 to 20% and particularly preferably about 5 to 15%, for example about 12%, the antistatic isostearamide usually 1 to 10% of the liquid Detergent composition, preferably 1 to 7% and more preferably about 3 to 7%, e.g. about 5%. The salary the water or aqueous medium of the liquid detergent is generally in the range from 3 to 80%, preferably 40 to 70%, more preferably about 45 to 65%, e.g. about 55%.

In the liquid detergent composition, the ratio of bentonite to antistatic is usually in that Range of one part of antistatic agent per 1 to 20 parts of bentonite, preferably in the range of 1: 1.5 to 4 and

particularly preferably from 1: 2 to 3, for example 1: 2.4. 20th

For preparing the liquid detergent compositions according to the invention the various components of the end product are usually only mixed or blended with one another and agitated or otherwise agitated sufficiently to produce a uniform liquid product. The sequence of encores the components can be chosen so that the best possible mixing is guaranteed. Usually is to Sufficient liquid medium is present at all times to prevent the solids from becoming deficient The liquid will cake together and avoid the formation of lumps that will later be difficult to disperse could. According to "normal" manufacturing methods, both soluble and insoluble are generally used finely divided components mixed with part of the aqueous medium and then the mixture is with the rest of the diluted aqueous medium. You can get the mixture through a

Let the homogenizer run to accelerate the dispersion of the components and their settling impede. In some cases, hydrotropes such as sodium cumene sulfonate and sodium xylene sulfonate, mostly in small amounts such as up to about 1 or 2% may be present in the formulation to help keep the liquid Keep composition homogeneous. Similarly, solvents such as ethanol and ethylene glycol or others can be used suitable glycols can be used to solubilize components. These solvents also help prevent the product from freezing or solidifying in cold weather. The various integral parts of the liquid detergent compositions are mostly in finely divided form in order to allow direct dissolution (if they are soluble) or dispersion in the aqueous medium accelerate. In general, the powdered materials are of smaller particle size than the numbers 140 or 200 US sieve series, these particle sizes are usually in the range of numbers 140 to 400, often preferably 200

up to 400, e.g. at around number 325 US sieve row. Easily soluble components such as sodium carbonate, sodium tripolyphosphate and the synthetic organic surfactants can have particle sizes similar to the larger sizes of the given ranges, or even larger, in the case of insoluble or slowly soluble materials such as the Zeolites and clays, the smaller particle sizes are generally more desirable.

To use the invention, laundry is washed with a liquid detergent in washing water, which is easily done in the usual way Is done with standard equipment and normal washing concentrations and where you get a clean wash, which is soft to the touch, does not adhere statically in an impermissible way, not even if there are significant amounts of synthetic Fibers such as polyesters, e.g. Dacron, and polyamides, e.g. nylon, are present. The applied washing water can

- 7Λ -

be common tap water. The invention liquid detergent compositions are also at great hardness of about 300 ppm, as calcium carbonate, and sometimes even more, effective. Usually the water hardness is one

mixed magnesium and calcium ion hardness, with the main part coming from calcium. Preferably the hardness is the Water no greater than 250 ppm. The tap water used usually has a hardness of 20 to 150 or 200 ppm, e.g. about 50 or 100 ppm. The invention Compositions can and are used in wash water at any temperature between 10 and 90 ° C effective even with wash water at lower temperatures, such as around room temperatures. According to European practice, the detergents in washing water ο

at temperatures close to the boiling point, for example 70 to 90 C, whereas lower temperatures are used in accordance with standard American practice. According to American practice, particularly good results are achieved when the compositions according to the invention are used in wash water at temperatures in the range from 10 to 50 ^° C., preferably 30 to 50 ^° C., for example at about 40 ^° C. The concentration of the liquid detergent in wash water can vary are varied according to the circumstances, but is mostly in the range from 0.1 to 0.5, preferably 0.1 to 0.4, and

particularly preferably 0.15 to 0.25, e.g. at about 0.2%. Consequently you can use half a measuring cup or 145 g of the liquid detergent in a washing machine containing about 65 l of water, often a density of about 1.1 to 1.3 g / ml, e.g. about 1.2 g / ml are used for washing a normal filling,

from about 2.7 to 4.5 kg, e.g. about 3.6 kg of dry laundry. If you want each wash load larger or smaller Volumes of liquid detergent used can vary the concentrations of the ingredients in the liquid Composition accordingly within practical

Limits are increased or decreased.

Usual household washing machines and the usual washing programs for these machines or commercial washing machines can be used be used. The laundry is washed in

a normal wash cycle for 2 to 30 minutes, e.g. 5 5

to 20 minutes, e.g., about 10 minutes, which is generally from the degree of soiling of the laundry and the type of fabric. When the wash cycle is finished, the laundry will be rinsed automatically and then dried in an automatic tumble dryer by tumbling it while drying air flows through it.

Instead of producing a liquid detergent that has all cleaning, builder and fabric softening properties and antistatic ingredients of the invention

Composition contains, in a variation of the invention, a liquid composition can be prepared, which contains fabric softening and antistatic components. Such a composition can be used together with a suitable liquid detergents as they are in large numbers

are on the market, are used to fabric soften the laundry washed with such a detergent and to impart antistatic properties. So can CISA or other suitable on nitrogen with a primary aliphatic group substituted isostearamides and

To further improve the behavior of the washed laundry. With the textile softening and antistatic supplement composition one is able to use the present invention

with any liquid detergent formulations 5

use and adapt to them. So it is left to the consumer, within reasonable limits determine how much softening and antistatic properties the laundry should receive. It is possible to do more of to use the supplement composition when using detergents that are particularly effective or "harsh" Laundry detergents are what require stronger softening and stronger antistatic treatment. Normally makes up 10 to 30% of the amount of fabric softener and antistatic agent present in the supplementary fluids, can

however, it can also be 10 to 50%, especially when a cosolvent such as ethanol is present. The ratio of Antistatic to bentonite is in the same ranges as above for the liquid detergent compositions indicated the both antistatic and plasticizers

contain.

Various advantages of the invention, most of which have already been pointed out, are presented in the following Working examples highlighted. That about nitrogen (primary)

Aliphatic substituted isostearamide antistatic agents do not react appreciably with bentonite nor with the anionic ones Surfactants, which is why compositions of the invention are relatively stable on storage and their desirable properties cleaning, softening and antistatic activities

do not lose significantly during storage or before or during use. Unlike the compositions based on the currently generally used cationic fabric softeners and antistatic agents such as quaternary ammonium salts store those according to the invention

Compositions do not contain reaction products of these cationic Materials with anionic surfactants on the too

washing laundry, so that such laundry is not so subject to dirt build-up during washing, when working according to the invention. The detergent compositions according to the invention lead as a result to one whiter laundry and also less redeposition of dirt, whereas laundry made with compositions is washed, the anionic surfactant and quaternary ammonium salt (in antistatic and textile-softening Amounts), tends to yellow, especially after repeated washing. The cleaning power is measurably better when using the detergents according to the invention than when using those in which a quaternary ammonium salt takes the place of isostearamide. An impairment of the foaming power of the anionic surfactant,

normally observed in the presence of cationic compounds such as quaternary ammonium salts, and Reactions of these "quats" with fluorescent brighteners and the resulting reduced glow of the laundry

avoided when using the antistatic agents according to the invention. 20th

Such undesirable interactions of anionic and cationic materials are particularly serious and unacceptable when using both the anionic surfactants and the cationic softening and antistatic agents Substances are in intimate contact for comparatively longer periods of time, as is the case when they are in in the same aqueous medium as, for example, in certain textile-softening anionic liquid detergents. Consequently brings the invention a significant improvement in detergent technology, it is important nowadays that Detergents have textile softening and antistatic properties in addition to excellent washing power.

The liquid detergents and make-up liquids of the invention are both preferably sufficiently viscous or thixotropic to keep finely divided components in suspension and prevent them from settling during storage. Nevertheless, the liquids should be free to flow from a bottle with a relatively narrow dispensing opening be. It has been found that liquids having viscosities in the range of 1,000 to 5,000 cps generally dissolve do not settle and have the desired flow properties. The liquids according to the invention therefore have in desirably viscosities in this range. In particular, this range is from 3,000 to 5,000, e.g.

Wt Pol · S O

4,000 <epe at room temperature (25 C). Although the viscosities of the compositions according to the invention are comparatively stable, it can be assumed that the ratio -15

Modest changes in manufacturing processes and storage conditions can affect the viscosity of the product that increases more than decreases when stored. If the viscosity or thickness increases excessively, and you get that too A pack or packaged bottle is placed in a shaker, the compositions generally become flow again and disperse the components that may have separated.

various textiles were rated by professionals. The protection that every textile part offers against the generation of electrical energy Charge (and significant static cling) when tumbling dry or other agitation was also demonstrated determined by that shown by the individual laundry items

The extent of electrostatic adhesion was observed. the Washed laundry was sufficiently soft and non-sticky.

Quantitative determinations of the electrostatic charge absorption of the various washed and dried items Textile parts were obtained by rubbing each textile part with wool in a controlled manner at a lower relative Humidity (25 to 30% R.F.) and measuring the charges accumulated by the sample parts. In this test it was a variety of sample parts used and from the

Readings calculated an average for each material. To get an antistatic index, which represents an overall rating of the antistatic ability of a liquid detergent composition has It has been shown to be expedient to use the sums of the charges on the materials mentioned. So this sum is for the liquid detergent according to the invention 12 kilovolts,

whereas the index for a comparative liquid detergent of the same formulation but omitting bentonite and CISA is 48 kilovolts. In the tests of the present invention, readings above 35 kilovolts were generally not acceptable (the laundry sticks considerably). When assessing the softness (terry towels were the washed ones Laundry items) received by a panel of experts with the liquid detergent of this example according to the above given procedures, towels washed the softness grade or softness rating 9 on a scale from 1 to 10, on which 10 indicates the greatest softness. Towels that washed with the comparative detergent in the same manner was rated 1.

In other tests, the degree of reprecipitation was from Dirt on the washed laundry is about the same with the product according to the invention as with a second comparative product that differs from the approach according to the invention Replacement of N-alkyl isostearamide with water differed. This reprecipitation was even worse in a third comparative product in which the isostearamide was replaced by the the same percentage of methyldistearylammonium chloride was replaced.

The test textile washed with the product according to the invention

tiles do not show the "quat stains" that one sometimes gets Can find laundry that has been washed with similar formulations which dimethyldistearylammonium chloride or other quaternary compounds in place of the N-isostearamide antistatic contain. There is also the effect of optical brightening in the case of the N-isostearamide according to the invention containing product larger than a similar product in which the isostearamide is replaced by dimethyldistearylammonium chloride or other such antistatic quaternary ammonium halide is replaced. Another Advantage of using CISA instead of the "Quat" or the

- ZSr- " ';

quaternary compound is an improvement in the appearance of the liquid detergent composition due to the Absence of any precipitated product from the reaction

of quaternary compound and anionic surfactant. 5

If you replaced the 5% N-cocoalkyl isostearmide by 1% _f 3% or 7% of this isostearamide in the specified approach of the product of the invention, the softness of the products obtained were 8, 8 and 9 and the static indices 27, 19 and 10. Softness indices of 8 or more are considered sufficient, as are static indices of less than 30, with softness indices as low as 7 and static indices as high as 35 being sometimes acceptable. If, as in the second comparative product, CISA was omitted from the approach, the washed laundry was rated with a softness of 8 and the electrostatic charge index was 36 kilovolts.

When comparing the first comparative product and the products of the invention in practical laundry tests, showed that the comparison product does not soften the laundry sufficiently and higher electrostatic charges like considerable Gluing results. If one omitted bentonite from the approach according to the invention as in the fourth comparative product,

one obtains detergent compositions, both in terms of their softening power as well as the Avoidance of static sticking are unsatisfactory, even if a relatively large proportion of the isostearamide is present. If you left out the isostearamide, you would

Despite the presence of 12% bentonite, inadmissible static sticking of the washed laundry was observed. Consequently it can be seen that the combination of bentonite and N (higher) -alkylisostearamide for the success of the invention Detergent compositions is important because 1.) This combination tends to give you greater antistatic Effect than could be foreseen; 2.) the bentonite

-so 36 ⁿ ^ 925

softens the laundry and 3.) by critical consumers today both textile softening and antistatic (das Adhesion-preventing) properties are required.

Instead of the preferred N-Cocoalkylisostearamids can other higher aliphatic isostearamides, preferably higher primary aliphatic isostearamides and especially higher primary N-alkyl isostearamides are preferably used such as N-n-octylisostearamide, N-n-decylisostearamide, N-n-heptylisostearamide, N-n-dodecylisostearamide, N-n-tetradecylisostearamide and N (primary hydrogenated) sebum x sostearam xd.

If you take the bentonite content of the formula given above modified within the range of 3 to 20%, for example adjusted to 10%, 15% and 18%, useful softening and antistatic detergent compositions were obtained. Even when the bentonite content was reduced to 5%, a noticeable fabric softening was achievable. Similarly, the proportions of anionic surfactant can be varied in the range from 3.5 to 25%, e.g. Bring 5%, 15% and 25%. The total content of builder salt can also be varied in the range from 5 to 40%, e.g. 10, 20 and 30%, with effective softening and antistatic detergent compositions available are. In all of these compositions, water represents the remainder with the exception of any auxiliary substances that may be present usually no more than 10%.

The bentonite used can be any of the other bentonites mentioned above can be replaced. Sometimes other source clays such as montmorillonite can be used Western or Wyoming bentonites are usually preferred. The sodium (linear) tridecylbenzenesulfonate can either in whole or in part by sodium (linear) dodecylbenzenesulfonate or other linear higher alkylbenzene

36Q1925

sulfonates with 10 to 15 or 18 carbon atoms or other anionic surfactants such as sodium lauryl sulfate, sodium cetyl sulfate, sodium paraffin sulfonate with about 16 Carbon atoms in the paraffin residue, and / or sodium cocomonoglyceride sulfate or any various mixtures thereof. In place of the ether sulfate other similar surfactants may occur such as sodium dodecyl pentaethoxy sulfate or other of the anionic mentioned above Surfactants. Polyphosphate can be replaced by other builders such as those previously mentioned, and so can

phosphate-free detergents are produced.

With the various modifications of the preferred approach given above according to the invention one obtains useful, fabric softening and antistatic detergent compositions, in the properties described above, the formulations are superior to the bentonite and isostearamide not included, as well as those in which quaternary ammonium salts were used instead of isostearamide.

Example 2

Instead of the complete, fabric softening and antistatic liquid detergent composition of the approach

Example 1 was produced in a modification of the 25th

Invention prepares a fabric softening and antistatic composition, which for the sake of simplicity as "Softening antistatic" is referred to and which in a liquid, aqueous medium bentonite and nitrogen (primary, higher) aliphatically substituted

Contains isostearamide (CISA). This liquid composition was made by simply mixing 14.1 parts of bentonite (American Colloid Company AEG 325 bentonite) and 5.9 parts of N-cocoalkylisostearamide with 80 parts of demineralized Water produced (although tap water is sufficient if you don't have demineralized water). The relationship

Nisse of bentonitrlsostearamide according to Example 1 can can also be used. Because of the thickening effect of the swelling bentonite, the powdery N-isostearamide is in the

aqueous medium kept suspended. The Softening Antistati-5

kum is done without further modification of the approach and can be bottled, shipped, stored, sold and used. However, it can be a cosolvent like Ethanol or hexylene glycol can be incorporated to accelerate the dissolution of N-isostearamide (and as To serve antifreeze), in which case a sufficient amount of ethanol or hexylene glycol or both are used to speed dissolution and prevent solidification. Also can be in the wording about 1% sodium xylene sulfonate is introduced as a hydrotrope, with or without 0.1 to 2% sodium polyacrylate, to disperse and / or suspend the bentonite in the aqueous system. Likewise can coloring Substances, antioxidants, buffers, gums, agents to prevent reprecipitation (sodium carboxymethyl cellulose

loose), optical brighteners and perfumes in usual quantities for Auxiliaries, mostly below 2% and often below 1%, are incorporated into the formulation.

The plasticizing antistatic can either be supplied by the manufacturer or can be added to another liquid detergent by the consumer in order to have the fabric softening and antistatic properties To improve properties of the same. The amount of softening antistatic added to the liquid detergent is chosen so that when the improved detergent composition is used, sufficient fabric softening and antistatic effects are guaranteed. Because of the diluting effect of the waxing antistatic, it is im generally desired a greater amount of the improved

Use detergent composition. Alternatively you can the concentrations of the active components in the softening antistatic as high as reasonably possible be kept possible in order to achieve optimal softening and antistatic effects. The liquid can also Softening antistatic agent is added directly to the washing water in the washing machine with the liquid detergent will. Any commercially available built-in detergent can be used with any of these application methods Base of anionic surfactants with regard to their textile softening and antistatic effects can be improved. The liquid softening antistatic can according to Invention can also be used as a means to impart softening and antistatic properties to laundry, those with any particulate or liquid detergent based on nonionic or amphoteric as well as anionic surfactants has been washed. In this way, the invention can be used with all known commercially available Use builder-containing detergent products successfully without the improvement achieved at the expense of Cleaning power, lightening or other desirable properties of this detergent is all about.

Example 3

A washing amount of the composition according to the formulation of Example 1 was used to wash a standard laundry load used in a common household washing machine (General Electric Top Loader). Alternatively, a washing amount was used (120 g) liquid detergent composition (similar to the first comparison product, without bentonite and CISA) the Wash water was added, followed by separate additions of the formulaic amounts of 17.6 grams of bentonite and 7.4 grams N-cocoalkylisostearamide (which may be dispersed in, can be dissolved in or mixed with a suitable liquid medium or particulate carrier,

and is preferably in 125 g of a softening antistatic as described in Example 2). The machine was treated with 65 liters of tap water with a hardness of about 100 ppm _? as calcium carbonate, mixed magnesium and calcium hardness, with the calcium hardness predominating, filled. The washing water had a temperature of 40 ^° C., the load of dirty laundry added to the washing water was about 3.6 kg. The washed laundry consisted of cotton, cotton-polyester blend, acetate and polyamide (nylon) and was soiled with normal dirt. Washing was carried out for 10 minutes, after which the laundry was automatically rinsed and spun. It was then dried in an automatic washing machine by tumbling it while hot drying air was passed through it. After drying it was

the laundry is assessed by a panel of experts. The evaluation found _r that the laundry was clean enough, it felt soft and was free from undue, electrostatic bonding. If the comparative composition is used in a similar (but only) manner, its formulation does not

Bentonite and no N-substituted isostearamide, the cleaning power proved to be able to wash similar laundry satisfactory, but the laundry felt significantly harder and exhibited electrostatic sticking, especially strong for laundry items with a synthetic content

polymer fibers.

Example 4

Instead of the composition of Example 2 for improvement

To use a liquid detergent or to add it to the wash water, it can also be used as an in rinse water emollient and antistatic agent can be used. In this embodiment of the invention that can liquid softening antistatic to the rinse water after washing the laundry with a conventional detergent composition can be added. Usually the amount of

Softening antistatic agent sufficient to keep the washed To make laundry recognizable antistatic and soft. For example, the amount added to the rinse water is 0.05 to 0.5%, preferably 0.1 to 0.3%, e.g. 0.2%. According to a typical example of this type of training Invention the laundry in the manner described in Example 1 with a detergent composition similar to that Example washed with the exception that bentonite and CISA were replaced by water (with the addition of a small amount of gum or other thickener added to the liquid to regulate viscosity, for example 0.1 to 1% CMC, PVA (polyvinyl alcohol), PVP (polyvinylpyrrolidone) or another for this purpose known gummy substance). After washing the

Laundry that was a normal, mixed filling of cotton and synthetic laundry became the The softening antistatic composition of Example 2 comprising 14.1 parts of bentonite and 5.9 parts of CISA in 80 parts contained demineralized water, the rinse water in a

Concentration of 0.2% added (130 g per 65 l of the 100 ppm hard rinse water). Then the laundry dried, sometimes after rinsing several times. After machine drying, it was low in electrostatic Load and was softer than comparative laundry that

was not subjected to the rinsing treatment described.
