Description

468 517 10 15 20 25 30 used in the manufacture of particulate detergent products. Although they have many advantages over solid or particulate solid products, liquid detergents also have certain inherent disadvantages which must be overcome in order to produce acceptable commercial detergent products.

Thus, some such products separate out during storage and others separate out during cooling and are not easily redispersible. In some cases, the product viscosity changes and the product becomes either too thick to pour or so thin that it appears watery. Some clear products become cloudy and other gels at rest.

The present inventors have been involved in the study of the behavior of nonionic liquid surfactant systems with particulate matter suspended therein. Of particular interest have been anhydrous reinforced liquid detergent compositions and the problem of sedimentation of the suspended builder and other detergent additives as well as the problem of gelling associated with nonionic surfactants. These considerations are important for, for example, product stability, pourability and dispersibility.

It is known that one of the main problems with reinforced liquid detergents is their physical stability.

This problem emanates from the fact that the density of the solid particles dispersed in the nonionic liquid surfactant is higher than the density of the liquid surfactant. This means that the dispersed particles tend to settle out. There are two basic solutions to solve the sedimentation problem, and they are increasing the viscosity of the nonionic liquid and reducing the particle size of the dispersed solid. It is known that suspensions can be stabilized against sedimentation by the addition of inorganic or organic thickeners or dispersants such as, for example, very high surface area inorganic materials, such as finely divided silica, clays, etc., organic. thickeners such as the cellulose ethers, acrylic and acrylamide polymers, polyelectrolytes, etc. However, such increases in the viscosity of the suspension are naturally limited by the requirement that the liquid suspension be easily pourable and flowable, even at low temperature. Furthermore, these additives do not contribute to the preparation's cleaning ability.

Grinding to reduce the particle size provides the following advantages: 1. The specific surface area of the dispersed particles is increased and as a result, particle wetting of the anhydrous vehicle (liquid nonionic agent) increases proportionally. 2. The average distance between dispersed particles is reduced by a proportional increase in particle-to-particle interaction. Each of these effects contributes to an increase in the rest gel strength and the yield strength of the suspension, while at the same time the grinding significantly reduces plastic viscosity.

The yield strength is defined as the minimum force required to induce a plastic deformation (flow) of the suspension. Thus, if the suspension is considered as a loose network of dispersed particles, if the applied force is lower than the yield strength, the suspension appears as an elastic gel and no plastic flow will occur. As soon as the yield strength is overcome, the network breaks at certain points and the sample begins to float, but with a very high apparent viscosity. If the shear force is much higher than the yield strength, the pigments are partially shear deflocculated and the apparent viscosity is reduced. Finally, if the shear force is much higher than the yield strength, the dispersed particles are completely shear deflocculated and the apparent viscosity is very low, as if there was no particle interaction.

Thus, the higher the yield strength of the suspension, the higher the apparent viscosity at low shear rate and the better the physical stability against sedimentation of the product.

In addition to the problem of sedimentation or phase separation, the anhydrous liquid detergent based on liquid nonionic surfactants suffer from the disadvantage that the nonionic agents tend to gel when added to cold water. This is a particularly important problem in the normal use of European automatic household washing machines, where the user places the detergent composition in a dosing unit (eg a dosing box) in the machine. During operation of the machine, the detergent in the dosing device is exposed to a stream of cold water for transferring it to the washing solution. Especially during the winter months, when the detergent composition and the water fed to the dosage unit are particularly cold, the detergent viscosity increases markedly and a gel is formed.

As a result, a portion of the composition is not completely flushed from the dosing unit during machine operation and a deposit of the composition builds up during repeated washing cycles, eventually requiring the user to flush the dosing unit with hot water.

The gelling phenomenon can also be a problem as soon as it is desired to carry out washing with cold water, such as is recommended for certain synthetic and sensitive textiles or textiles which can shrink in hot or hot water.

The gel tendency of the concentrated detergent compositions during storage is enhanced by storing the compositions in unheated storage spaces or by shipping the compositions during the winter months in unheated transport spaces.

Sub-solutions to the gelling problem have been proposed, for example by diluting the liquid nonionic agent with certain viscosity regulating solvents and gel inhibiting agents, such as lower alkanols, eg ethyl alcohol (cf. U.S. Patent No. 3,953,380), alkali metal formats and addipates (cf. U.S. Pat. No. 4,368,147), hexylene glycol, polyethylene glycol, etc., and modification and optimization of the nonionic structure. As an example of modification of nonionic surfactant, a particularly favorable result has been obtained by acidifying the hydroxyl end group in the nonionic molecule. The benefits of introducing a carboxylic acid at the end of the nonionic agent include gel inhibition upon dilution, lowering of the pour point of the nonionic agent, and formation of an anionic surfactant upon neutralization in the wash liquor. Optimization of the nonionic structure has centered on the chain length of the hydrophobilipophilic moiety and the number and composition of the alkylene oxide (eg, ethylene oxide) moieties in the hydrophilic moiety. For example, it has been found that a C13 fatty alcohol ethoxylated with 8 moles of ethylene oxide has only a limited gelling tendency.

Nevertheless, improvements in both stability and gel inhibition for anhydrous liquid textile treatment compositions are sought. In accordance with the present invention, a highly concentrated stable anhydrous liquid detergent composition is prepared by adding to the composition small effective amounts of a sedimentation inhibiting stabilizing urea additive or small effective amounts of a quaternary surfactant ammonium-containing agent. as a sedimentation-inhibiting stabilizing additive.

The compositions of the present invention contain as an essential ingredient a sedimentation inhibiting stabilizing urea additive or a quaternary ammonium surfactant containing agent as a sedimentation inhibiting stabilizing additive.

The sedimentation inhibiting stabilizing urea additive is believed to act in the detergent composition as a surfactant which makes the phosphate detergent builder more compatible with the nonionic surfactant detergent.

Urea is believed to interact with the anionic phosphate detergent builder salts and make these builder salts more compatible with the nonionic surfactant and improve the contact between the builder salts and the nonionic surfactant. The improvement in the contact between the phosphate and the nonionic surfactant improves the stability of the phosphate suspension in the nonionic surfactant.

The urea compound, even when added to the composition in small amounts, improves the dispersibility of the builder salt suspension by counteracting gel formation of the builder salt suspension.

The urea compound improves the dispersibility by inhibiting gelation of the suspension of detergent builder salt particles when water is added to the composition, for example in the dosing box of a dishwasher and / or when the composition is added to water.

The urea compound used in the compositions of the present invention has the formula HZNCONHZ. Urea forms a tautomer that has the formula HZNCNHOH and is called urea.

The quaternary ammonium-containing sedimentation inhibiting stabilizing additives are cationic surfactants.

The quaternary ammonium-containing cationic surfactants useful in the present invention are those surfactants which contain a long chain hydrophobic hydrocarbon group in their molecular structure and a hydrophilic group, i.e. a water-soluble salt-forming anion group.

The preferred quaternary ammonium compounds used in accordance with the present invention are the mono- and di-higher alkyl-lower alkyl-quaternary ammonium salts and the mono- and di-higher alkyl-diethoxylated-quaternary ammonium salts.

The quaternary ammonium salts are believed to interact with anionic phosphate detergent builder salts by coating the anionic phosphate with a lipophilic skin. The lipophilic coating makes the anionic phosphate detergent builder salts more compatible with the nonionic surfactant and improves the contact between the phosphate and the nonionic surfactant. The improvement in the contact between the phosphate and the surfactant improves the stability of the phosphate suspension in the nonionic surfactant. The preferred cationic quaternary surfactant ammonium-containing sedimentation inhibiting stabilizers of the present invention are included in the group consisting of: I.

To improve the viscosity properties of the composition, an acid-terminated nonionic surfactant can be added. To further improve the viscosity and storage properties of the composition, viscosity enhancing and gel inhibiting agents such as alkylene glycols, polyalkylene glycols and alkylene glycol monoalkyl ethers and additional sedimentation inhibitors such as phosphoric acid ester and / or aluminum stearate may be added to the composition. According to one embodiment of the invention, the detergent composition contains an acid-terminated nonionic surfactant, an alkylene glycol monoalkyl ether and a urea sedimentation inhibiting stabilizer or a quaternary ammonium sedimentation inhibiting stabilizer.

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

According to one embodiment of the invention, the enhancer components of the composition are ground to a particle size of less than 100 microns and preferably to below 10 microns to further improve the stability of the suspension of the enhancer components in the liquid nonionic surfactant detergent.

In addition, other ingredients may be added to the composition such as antifouling agents, antifoams, optical brighteners, enzymes, anti-redeposition agents, perfumes and dyes. 10 15 20 25 30 468 517 ll Washing machines for home use of today normally work at washing temperatures of up to 9500. About 70 liters of water were used during the washing and rinsing cycles.

About 200-250 g of powdered detergent per wash are normally used.

In accordance with the present invention, where the highly concentrated liquid detergent is used, only 100 g (78 ml) of the liquid detergent composition is normally required to wash a full load of dirty laundry.

Thus, in one aspect, the present invention provides a liquid high performance detergent composition composed of a suspension of a detergent builder salt or of an anionic detergent builder salt, for example a phosphate builder salt, in a liquid nonionic surfactant, the composition comprising an effective amount of a urea compound for increasing the stability of the suspension against sedimentation and the dispersibility of the suspension in water or a quaternary ammonium surfactant for increasing the stability of the suspension against sedimentation.

In another aspect, the invention provides a concentrated liquid high performance detergent composition which is stable, non-sedimenting during storage and non-gelling during storage and use.

More particularly, there is provided a method of filling a container with an anhydrous liquid detergent composition in which the detergent is at least predominantly composed of a liquid nonionic surfactant and for dosing the composition from the container into an aqueous liquid. washing bath, the dosing being performed by directing a stream of unheated water towards the composition so that the composition of the water stream is transported into the washing bath.

The addition of the urea compound to the detergent compositions reduces the problem of dispersion of dispersed particles and phase separation and improves the dispersibility of the suspended detergent particles in water. The addition of the quaternary ammonium-containing surfactants to the detergent compositions reduces the problem of sedimentation and phase separation of the dispersed particles.

The concentrated anhydrous liquid nonionic surfactant compositions of the present invention have the advantages of being stable, non-sedimentary on storage and non-gelling on storage. The liquid compositions are easy to pour, easy to measure and easy to insert into the washing machines.

An object of the present invention is to provide a stable liquid high performance anhydrous nonionic detergent composition containing at least one urea compound as a sedimentation inhibiting stabilizer and optionally an anionic phosphate detergent builder salt suspended in a nonionic surfactant.

Another object of the present invention is to provide a stable liquid high performance anhydrous nonionic detergent composition containing at least one quaternary ammonium containing sedimentation inhibiting stabilizer and at least one anionic phosphate detergent builder salt suspended in a nonionic surfactant.

Another object of the invention is to provide liquid textile treatment compositions which are suspensions of insoluble inorganic particles in an anhydrous liquid and which are storage stable, easily pourable and easily dispersible in cold, hot or hot water.

Another object of the present invention is to formulate highly reinforced high performance anhydrous liquid nonionic surfactant compositions which can be poured at any temperature and which can be repeatedly dosed from the dosing unit in European automatic washing machines without depositing or plugging the dosing device even during the winter months.

A specific object of the invention is to provide non-gelling, stable suspensions of high performance enhanced anhydrous liquid nonionic detergent compositions which comprise an effective amount of a urea compound or a quaternary ammonium containing surfactant sufficient to increase the composition of the composition. yield strength to thereby increase its stability, i.e. prevent sedimentation of builder particles, etc., preferably during reduction or at least without increasing the plastic viscosity of the composition (viscosity under shear conditions).

These and other objects of the invention, which will become more apparent from the following detailed description of preferred embodiments, are generally achieved by the preparation of a detergent composition by adding to the anhydrous liquid nonionic surfactant a an effective amount of a urea compound as a sedimentation inhibiting stabilizer or a quaternary ammonium containing surfactant as a sedimentation inhibitory stabilizer sufficient to prevent sedimentation of the suspended particles, said composition comprising inorganic or organic textile treatment additives, eg viscosity enhancing agents and one or more anti-gelling agents, anti-caking agents, pH-controlling agents, bleaching agents, bleach activators, defoamers, optical brighteners, enzymes, anti-redeposition agents, perfumes and dyes.

In accordance with the present invention, the physical stability of the suspension of the anionic phosphate detergent builder compound or anionic detergent builder compound and any other suspended additives such as bleaching agents, etc. in the liquid nonionic surfactant is substantially improved by the addition of a sedimenting or stabilizing agent. ammonium-containing surfactant.

The addition of very small amounts of the sediment-inhibiting stabilizing urea compound or the quaternary ammonium surfactant as a sediment-inhibiting stabilizing agent is sufficient to significantly improve the physical stability of the detergent compositions. The urea compound also significantly improves the dispersibility of the compositions in water.

According to an embodiment of the present invention, the compositions contain as an essential ingredient a sedimentation inhibiting stabilizing urea additive. The sedimentation inhibiting stabilizing additive may be one or more urea compounds.

The urea compounds used in the compositions of the present invention have the formula R 1 R 2 N 2 NR 3 R 4 X wherein at least one of the R 1 - R 4 groups is hydrogen and the residue is alkyl, preferably C 1 -C 4, alkyl, aryl, preferably phenyl, hydroxyl or chlorine, and X is O or NH.

Urea forms a tautomer that has the formula HZNCNHOH and is called urea. Urea and urea compounds and derivative compounds such as methylurea, dimethylurea, ethylurea, propylurea, butylurea, hydroxylurea and phenylurea and salts thereof are suitable for use in the present invention.

In addition to acting as a physical stabilizer, the urea compounds have the advantages over other physical stabilizers that they are compatible with the nonionic surfactant component and that they significantly improve the dispersibility of the composition in cold water.

Without attaching to any particular theory of the manner in which the urea or urea compounds prevent sedimentation of the suspended anionic phosphate enhancer detergent particles, it is believed that the urea or urea compounds interact with the anionic phosphate detergent so that the non-phosphorus enhancer surfactant, improves the contact between the phosphate and the surfactant and improves the wettability of the surfaces of the dispersed solid phosphate particles of the nonionic surfactant. The improvement of the contact between the phosphate 468 10 15 20 25 30 517 16 and the nonionic surfactant and the improved wettability of the dispersed phosphate particles of the nonionic surfactant increase the stability of the phosphate suspension in the nonionic surfactant and allow the suspended phosphate to more easily in suspension.

The improved physical stability is manifested by an increase in the yield strength of the composition compared to the same composition without the stabilizer. As described above, the higher the yield strength, the higher the apparent viscosity at low shear rates and the better the physical stability.

The urea compound, even when added to the composition in small amounts, improves the dispersibility of the builder salt suspension by inhibiting gelation in the builder suspension when it is contacted with water.

The urea compound improves dispersibility by inhibiting gel formation in the suspension of detergent builder salt particles, when water is added to the composition, for example in the dosing box of a dishwasher and / or when the composition is added to the washing water.

Only very small amounts of the urea compound are required to achieve the significant improvements in physical stability of the detergent composition and to improve the dispersibility of the composition in cold water.

By way of example, suitable amounts of urea are in the range of about 0.1 - 5%, preferably about 0.2 - 2% and more preferably about 0.5 - 1.5%, based on the total weight of the nonionic liquid surfactant composition. .

According to another embodiment of the present invention, the compositions contain as an essential ingredient an anti-sedimentation stabilizing surfactant quaternary ammonium-containing additive. The anti-sedimentation stabilizing additive may comprise one or more quaternary ammonium-containing surfactants.

The anionic surfactants useful in the present invention are the cationic surfactants which contain a long chain hydrophobic hydrocarbon group in their molecular structure and a hydrophilic group, i.e. a water-soluble salt-forming anion group.

The terms "soy" and "tallow", etc., in the sense used herein refer to the source from which the long chain fatty alkyl chains are derived. Mixtures of the sedimentation inhibiting stabilizers containing quaternary ammonium compound can be used.

The linear higher alkyl-quaternary ammonium salts are readily biodegradable and are preferred. Although the applicant does not wish to be bound by any particular theory for the manner in which the quaternary ammonium compound surfactants prevent sedimentation of the suspended anionic phosphate detergent builder particles, it is believed that the quaternary ammonium salts interact with the anionic phosphate detergent anionic phosphate detergents. coated with a cationic lipophilic skin which makes the phosphate more compatible with the nonionic surfactant, improves the contact between the phosphate and the nonionic surfactant and increases the wettability of the surfaces of the dispersed solid phosphate particles of the nonionic surfactant. The improvement in the contact between the phosphate and the nonionic surfactant and the improved wettability of the dispersed phosphate particles of the nonionic surfactant increase the stability of the phosphate suspension and allow the suspended phosphate to remain more easily in suspension.

The increased physical stability is manifested by an increase in the yield strength of the composition of, for example, from 65 dynes / cm 2 to 260 dynes / cm 2 and an increase in the apparent viscosity of, for example, from 2350 to 3250 (LVT , spindle no. 4, 60 rpm), compared with the same composition without quaternary ammonium salt stabilizer.

As described above, the higher the yield strength, the higher the apparent viscosity at low shear rate and the better the physical stability.

In addition to their action as a physical stabilizer, the higher alkyl quaternary ammonium salts have the additional advantages over other physical stabilizers in that they are cationic in nature and are compatible with the nonionic surfactant component.

Only very small amounts of the quaternary ammonium salt stabilizer are required to achieve the significant improvements in physical stability. For example, suitable amounts of the quaternary ammonium salt are in the range of about 0.1 - 5%, preferably about 0.3 - 2.0% and more preferably about 0.5 - 1.5%, based on the nonionic liquid surfactant composition. total weight. Although the urea compounds and the quaternary ammonium salts are effective in their physical stabilizing action, other known physical stabilizers such as an acidic organic phosphorus compound having an acidic -POH group, such as a partial ester of phosphoric acid and a alkanol and / or an aluminum salt of a fatty acid.

The nonionic synthetic organic detergents utilized in the practice of the invention may be any of a large number of known compounds.

As is known, the nonionic synthetic organic detergents are characterized by the presence of an organic hydrophobic group and an organic hydrophilic group and they are prepared typically by the condensation of an organic aliphatic or alkyl aromatic hydrophobic compound with ethylene oxide (which is hydrophilic to nature). Virtually any hydrophobic compound having a carboxy, hydroxy, amido or amino group with a free hydrogen bonded to the nitrogen can be condensed with ethylene oxide or with its polyhydration product polyethylene glycol to form a nonionic detergent. The length of the hydrophilic or polyoxyethylene chain can be easily adjusted to achieve the desired balance between the hydrophobic and hydrophilic groups. Typical suitable nonionic surfactants are those described in U.S. Patent Nos. 4,316,812 and 3,630,929.

Typically, the nonionic detergents are poly-lower alkoxylated lipophils where the desired hydrophilic-lipophilic balance is achieved by adding a hydrophilic poly-lower alkoxy group to a lipophilic moiety. A preferred class of the nonionic detergent used is the poly-lower alkoxylated-higher alkanol where the alkanol has 9 to 18 carbon atoms and where the number of moles of lower alkylene oxide (having 2 or 3 carbon atoms) is 3 to 12. Of such materials, those used are preferably those The higher alkanol is a higher fatty alcohol having 9 to 11 or 12 to 15 carbon atoms and containing 5 to 8 or 5 to 9 lower alkoxy groups per mole. Preferably the lower alkoxy group is ethoxy but in some cases it may be desirable to mix it with propoxy, the latter presently being a minor proportion (less than 50%).

Examples of such compounds are those in which the alkanol has 12 to 15 carbon atoms and which contain about 7 ethylene oxide groups per mole, for example Neodol 25-7 and Neodol 23-6.5, which products are manufactured by Shell Chemical Company, Inc.

The former is a condensation product of a mixture of higher fat alcohols with an average of about 12 - 15 carbon atoms with about 7 moles of ethylene oxide and the latter is a corresponding mixture where the carbon atom content of the higher fat alcohol is 12 - 15 13 and the number of ethylene oxide groups present on average amounts to about 6.5. The higher alcohols are primary alkanols.

Other examples of such detergents include Tergitol 15-S-7 and Tergitol 15-S-9, both of which are linear secondary alcohol ethoxylates manufactured by Union Carbide Corp. The former is a mixed ethoxylation product of linear secondary alkanol having 11 to 15 carbon atoms with 7 moles of ethylene oxide and the latter is a similar product but reacted with 9 moles of ethylene oxide.

As a component of the nonionic detergent, the present composition can also use higher molecular weight nonionic agents such as Neodol 45-111, which are similar to ethylene oxide condensation products of higher fatty alcohols, where the higher fatty alcohol has 14 to 15 carbon atoms and the number of ethylene oxide groups per mole is ca ll.

Such products are also manufactured by Shell Chemical Co.

Other useful nonionic agents are represented by the commercially well known class of nonionic agents sold under the trademark Plurafac. The plurafac agents consist of the reaction product of a higher linear alcohol and a mixture of ethylene and propylene oxides, containing a mixed chain of ethylene oxide and propylene oxide terminated by a hydroxyl group. Examples include products that are (A) C13-C15 fatty alcohol condensed with 6 moles of ethylene oxide and 3 moles of propylene oxide, (B) C13-C15 fatty alcohol condensed with 7 moles of propylene oxide and 4 moles of ethylene oxide, (C) C13-C15 fatty alcohol condensed with 5 moles of propylene oxide and 10 moles of ethylene oxide and (D) a product consisting of a 1: 1 mixture of products (B) and (C). Another group of liquid nonionic agents are commercially available from Shell Chemical Company Inc. under the trademark Dobanol: Dobanol 91-5 is an ethoxylated C9-C11 fatty alcohol having an average of 5 moles of ethylene oxide and Dobanol 25 -7 is an ethoxylated C12-C15 fatty alcohol with an average of 7 moles of ethylene oxide per mole of fatty alcohol.

In the preferred poly-lower alkoxylated-higher alkanols, in order to achieve the best balance between hydrophilic and lipophilic units, the number of lower alkoxy groups usually amounts to 40-100% of the number of carbon atoms in the higher alcohol, and preferably constitutes 40-60% thereof. and the nonionic detergent preferably contains at least 50% of said preferred poly-lower alkoxy-higher alkanol. Higher molecular weight alkanols and various other normally solid nonionic detergents and surfactants may contribute to the gelation of the liquid detergent and, as a consequence, they are preferably omitted or limited in quantity in the present compositions, although minor proportions thereof may both for the preferred and less preferred nonionic detergents, the alkyl groups therein are usually linear a carbon adjacent to the straight chain and although branching can be tolerated as at or two carbon atoms from the end carbon in that of the ethoxy chain, if such branched alkyl is not longer than three carbon atoms in length. Normally, the proportion of carbon atoms in such a branched configuration is only a small part and seldom exceeds 20% of the total carbon atom content of the alkylene. Similarly, although linear alkyls terminally attached to the ethylene oxide chains are highly preferred and are considered to result in the best combination of cleaning ability, biodegradability and non-gelling properties, medial or secondary binding to the ethylene oxide in the chain may occur. . Usually this is only in a small proportion of these alkyls, usually less than 20%, but as in the case of the said Tergitols, the proportion may be greater . Furthermore, when propylene oxide is present in the lower alkylene oxide chain, it usually constitutes less than 20% and preferably less than 10% thereof.

When larger proportions of non-terminally alkoxylated alkanols, propylene oxide-containing poly-lower alkoxy alkanols and less hydrophilic-lipophilically balanced nonionic detergents than mentioned above are used, and when other nonionic detergents are used in place of the preferred nonionic detergents set forth herein, the resulting product may not have as good cleaning ability, stability, viscosity and non-gelling properties as the preferred compositions, but use of the viscosity and gel controlling compounds of the invention may also improve the properties of the detergents based on such nonionic agents. In some cases, such as when a higher molecular weight poly-lower alkoxy-higher alkanol is used, often for its cleaning ability, its proportion is controlled or limited according to the results obtained in routine experiments, in order to achieve the desired cleaning ability and while maintaining of the product with the desired viscosity and non-gelling. Furthermore, it has been found that it is only rarely necessary to use the higher molecular weight nonionic agents for their cleaning properties, since the preferred nonionic agents described herein are excellent detergents and, in addition, allow the desired viscosity of the liquid detergent to be achieved without gelling at low temperatures.

Another useful group of nonionic surfactants is the "Surfactant T" series of nonionic agents which can be obtained from British Petroleum. Sufactant T-nonionic agents are obtained by ethoxylating secondary Cn fatty alcohols with a narrow ethylene oxide distribution. Sufactant T5 has an average of 5 moles of ethylene oxide, Sufactant T7 an average of 7 moles of ethylene oxide, Surfactant T9 has an average of 9 moles of ethylene oxide and Sufactant T12 has an average of 12 moles of ethylene oxide per mole of secondary Cu fatty alcohol.

In the compositions of this invention, the preferred surfactants include the Cu-Cm secondary fatty alcohols having a relatively narrow content of ethylene oxide in the range of about 7-9 moles, and the C4-Cn fatty alcohols ethoxylated with about 5-6 moles. ethylene oxide.

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

The viscosity and gel properties of the liquid detergent compositions can be improved by incorporating into the composition an effective amount of an acid-terminated liquid nonionic surfactant. The acid-terminated nonionic surfactants consist of a nonionic surfactant which has been modified by converting a free hydroxyl group therein to a moiety having a free carboxyl group, such as an ester or a partial ester of a nonionic surfactant and a polycarbonate. boxylic acid or anhydride.

The free carboxyl group-modified nonionic surfactants, which can generally be characterized as polyether carboxylic acids, work by lowering the temperature at which the liquid nonionic agent forms a gel with water. 10 15 20 25 30 468 517 29 The addition of the acid-terminated nonionic surfactants to the liquid nonionic surfactant contributes to the dosability of the composition, i.e. pourability, and lowers the temperature at which the liquid nonionic surfactants form a gel in water without a lowering of their stability to sedimentation. The acid-terminated nonionic surfactant reacts in the washing machine water with the alkalinity of the dispersed builder salt phase in the detergent composition and acts as an effective anionic surfactant.

Specific examples include the half esters of product (A) with succinic anhydride, the ester or half ester of Dobanol 25-7 with succinic anhydride and the ester or half ester of Dobanol 91-5 with succinic anhydride.

Instead of succinic anhydride, other polycarboxylic acids or anhydrides may be used, for example maleic acid, maleic anhydride, glutaric acid, malonic acid, phthalic acid, phthalic anhydride, citric acid and the like.

The acid-terminated nonionic surfactants can be prepared as follows: Acid-terminated product (A). 400 g of product (A) nonionic surfactant, which is a C13-C15 alkanol alkoxylated by the introduction of 6 ethylene oxide and 3 propylene oxide units per alkanol unit, is mixed with 32 g of succinic anhydride and heated for 7 hours at 100 ° C. The mixture is cooled and filtered to remove unreacted succinic acid material. IR analysis indicates that about half of the nonionic surfactant has been converted to its acidic ester.

Acid-terminated Dobanol 25-7. 522 g of Dobanol 25-7 nonionic surfactant, which is the product of ethoxylation of a C12-C15 alkanol and contains about 7 ethylene oxide units 468 537 10 per 20 alkanol molecule, is mixed with 100 g of succinic anhydride and 0, 1 g of pyridine (which acts as an esterification catalyst) and heated at 260 DEG C. for 2 hours, cooled and filtered to remove unreacted succinic acid material. IR analysis indicates that substantially all of the free hydroxyl groups in the surfactant have been reacted.

Acid terminatorlkbanol 91-5. 1,000 g of Dobanol 91-5 nonionic surfactant, which is the product of ethoxylation of a C9-C11 alkanol and has about 5 ethylene oxide units per alkanol molecule, is mixed with 265 g of succinic anhydride and 0.1 g of pyridine catalyst and heated at 26,000 g. for 2 hours, cooled and filtered to remove unreacted succinic acid material. IR analysis shows that essentially all of the free hydroxyl groups in the surfactant have been reacted.

Other esterification catalysts such as an alkali metal alkoxide (eg sodium methoxide) may be used in place of or in admixture with the pyridine.

The acidic polyether compound, i.e. the acid-terminated nonionic surfactant, is preferably added dissolved in the nonionic surfactant.

The liquid anhydrous nonionic surfactant used in the compositions of the present invention contains therein dispersed and suspended fine particles of inorganic and / or organic detergent builder salts.

The detergent compositions of the invention comprise water-soluble and / or water-insoluble detergent builder salts. Water-soluble inorganic alkaline builder salts which can be used alone with the detergent compound or in admixture with other builders are alkali metal carbonates, bicarbonates, borates, phosphates, polyphosphates and silicates. (Ammonium or substituted ammonium salts may also be used.) Specific examples of such salts are sodium tripolyphosphate, sodium carbonate, sodium tetraborate, sodium pyrophosphate, potassium pyrophosphate, sodium bicarbonate, potassium tripolyphosphate, sodium hexonaphthonate carbonate and sodium hexamethonaphthonate. Sodium tripolyphosphate (TPP) is especially preferred.

Since the compositions of the present invention are generally highly concentrated and therefore can be used in relatively low doses, it is desirable to supplement any phosphate builder (such as sodium tripolyphosphate) with an auxiliary builder such as a poly-lower carboxylic acid or a polymeric carboxylic acid having high calcium binding capacity for incrustation, which could otherwise be caused by the formation of an insoluble calcium phosphate.

A suitable lower polycarboxylic acid comprises alkali metal salts of lower polycarboxylic acids, preferably sodium and potassium salts. Suitable lower polycarboxylic acids have 2 to 4 carboxylic acid groups. Preferred sodium and potassium lower polycarboxylic acid salts are citric and tartaric acid salts.

The sodium citric acid salts are the most preferred, especially the trisodium citrate. The monosodium and disodium citrates can also be used. The monosodium and disodium tartaric acid salts can also be used. The alkali metal lower polycarboxylic acid salts are particularly good builder salts because they, due to their high calcium and magnesium binding capacity, can prevent crusting, which could otherwise be caused by the formation of insoluble calcium and magnesium salts.

Other organic builders are polymers and copolymers of polyacrylic acid and polymaleic anhydride and alkali metal salts thereof. More specifically, such builder salts may consist of a copolymer, which is the reaction product of approximately equal moles of methacrylic acid and maleic anhydride, which has been completely neutralized to form its sodium salt. The amplifier is commercially available under the Sokalan CP5 brand. This amplifier also works when used in very small amounts by preventing crusting.

Examples of organic alkaline sequestering builder salts which can be used with the detergent builder salts or in admixture with other organic or inorganic builders are alkali metal, ammonium or substituted ammonium aminopolycarboxylates, for example sodium and potassium ethylenediaminetetraacetate (ED) potassium nitrilotriacetates (NTA) and triethanolammonium N- (2-hydroxyethyl) nitrilodiacetates. Mixed salts of these aminopolycarboxylates are also suitable.

Other suitable builders of the organic type include carboxymethyl succinates, tartronates and glycolates.

Particularly valuable are the polyacetal carboxylates. The polyacetal carboxylates and their use in detergent compositions are described in U.S. Patent Application Laid-Open No. 4,144,226, 4,315,092 and 4,146,495.

The alkali metal silicates are useful builder salts which also effect adjustment or control of the pH and render the composition anticorrosive to washing machine parts.

Sodium silicates with Na 2 O / SiO 2 ratios of 1.6 / 1 - 1 / 3.2, especially about 1/2 - l / 2.8 are preferred. Potassium silicates with the same ratios can also be used.

Other typical suitable builders include, for example, those described in U.S. Patent Nos. 4,316,812, 4,264,466 and 3,630,929. The inorganic builder salts may be used in conjunction with the nonionic surfactant detergent compound or in admixture with other inorganic builder salts or with organic builder salts. The water-insoluble crystalline and amorphous aluminosilicate zeolites can be used. The zeolites have the general formula (M2O) x '(Al2O3) y' (SiO2) z 'WHZO where x is 1, y is 0.8 - 1.2, preferably 1, z is 1.5 - 3.5 or higher and preferably 2 - 3 and w is 0 - 9, preferably 2.5 - 6 and M is preferably sodium. A typical zeolite is type A or similar structure with type 4A being particularly preferred. The preferred aluminosilicates have calcium ion exchange capacities of about 200 milliequivalents per gram or higher, eg 400 meq / g.

Various crystalline zeolites (i.e., aluminosilicates) that can be used are described in GB Patent No. 1,504,168, U.S. Patent No. 4,409,136 and CA Patent Nos. 1,072,835 and 1,087,477, all of which are incorporated herein by reference for these disclosures. An example of amorphous zeolites that can be used herein is found in Belgian Patent Specification 835,351 and also this patent is incorporated herein by reference.

Other materials such as clays, especially of the water-insoluble types, may be useful additives in the compositions of the present invention. Particularly useful is bentonite. This material is primarily montmorillonite, which is a hydrated aluminosilicate in which about 1/6 of the aluminum atoms may be exchanged for magnesium atoms 468 517 10 15 20 25 30 34 and to which varying amounts of hydrogen, sodium, potassium, calcium, etc. may be loosely connected. The bentonite in its more purified form (i.e. free from any gravel, sand, etc.) suitable for detergents contains at least 50% montmorillonite and its cation exchange capacity is thus at least about 50-75 meq per 100 g of bentonite. Particularly preferred bentonites are the Wyoming or Western U.S. bentonites which have been sold as Thixo-gels 1, 2, 3 and 4 by Georgia Kaolin Co. These bentonites are known to soften textiles as described in GB Patent Nos. 401,413 and 461,221.

The incorporation into the detergent composition of an effective amount of viscosity control and gel inhibiting agent for the nonionic surfactant improves the storage properties of the composition. The viscosity controlling and gel inhibiting agents function to lower the temperature at which the nonionic surfactant forms a gel when added to water. Such viscosity controlling and gel inhibiting agents may be, for example, lower alkanol, eg ethyl alcohol (cf. U.S. Patent No. 3,953,380), hexylene glycol, polyethylene glycol, eg polyethylene glycol having a molecular weight of about 400 (PEG 400) and alkylene oxide lower monoalkyl ether amphiphilic compounds. with low molecular weight.

Preferred viscosity controlling and gel inhibiting compounds are the low molecular weight amphiphilic compounds. The amphiphilic compounds act as viscosity controlling and gel inhibiting agents for the nonionic surfactant and significantly improve the storage properties of the composition. The amphiphilic compounds can be considered analogous in chemical structure to the ethoxylated and / or propoxylated fatty alcohol liquid nonionic surfactants but have relatively short hydrocarbon chain lengths (C 2 - C 8) and a low content of ethylene oxide (about 2 - 6 ethylene oxide groups per molecule).

Suitable amphiphilic compounds are represented by the following general formula: R 30 (cH cH 0) H 2 2 n where R 3 is a C 2 - C 8 alkyl group and n is a number from about 1 to 6, on average.

Specifically, the compounds are lower (C2 - C3) alkylene glycol mono-lower (C2 - C5) alkyl ethers.

More specifically, the compounds are mono-, di- or tri-lower (C2 - C3) alkylene glycol mono-lower (C1-C5) alkyl ethers.

Specific examples of suitable amphiphilic compounds include ethylene glycol monoethyl ether (C2H5-O-CH2CH2OH) diethylene glycol monobutyl ether (C4H9-O- (CH2CH2O) 2H) tetraethylene glycol monobutyl ether (C4H7-O- (CH2CH2O2H2O2HethylO 2H).

CH3 Diethylene glycol monobutyl ether is especially preferred.

The incorporation into the composition of the lower molecular weight lower alkylene glycol monoalkyl ether reduces the viscosity of the composition, so that it becomes easier to pour, the stability against sedimentation is improved, as well as the dispersibility of the composition when added to hot or cold water.

The compositions of the present invention have improved viscosity and stability properties and become stable and durable at temperatures as low as about 5 ° C and lower.

In addition to acting as sedimentation inhibiting stabilizers, the urea compounds improve the dispersibility of the suspension of phosphate detergent builder particles by inhibiting gelation of the suspended particles when cold water is added to the composition in the dosing box and / or when adding water to the composition. .

According to an embodiment of the invention, a supplemental stabilizer which is an alkanol ester of phosphoric acid or an aluminum salt of a higher fatty acid may be added to the preparation.

Improvements in the stability of the composition can be achieved by the incorporation of a small effective amount of an acidic organic phosphorus compound with an acidic POH group such as a partial ester of phosphoric acid and an alkanol.

The acidic organic phosphorus compound with an acidic POH group can increase the stability of the suspension of builders in the anhydrous liquid nonionic surfactant.

The acidic organic phosphorus compound may be, for example, a partial ester of phosphoric acid and an alcohol such as an alkanol having a lipophilic character having, for example, more than 5 carbon atoms, for example 8 to 20 carbon atoms.

A specific example is a partial ester of phosphoric acid and a CE-C 1-4 alkanol (Empiphos 5632 from Marchon), which is composed of about 35% monoester and 65% diester.

The incorporation of very small amounts of the acidic organic phosphorus compound makes the suspension stable against sedimentation at rest, but it remains pourable while for the low concentration of stabilizer, for example below about 1%, its plastic viscosity generally decreases.

Improvements in the stability and anti-sedimentation properties of the composition can also be achieved by the addition of a small effective amount of an aluminum salt of a higher fatty acid to the composition.

The aluminum salt stabilizers are the subject of US-SN 725 455, filed April 22, 1985, the disclosure of which is incorporated herein by reference.

The preferred higher aliphatic fatty acids have about 8 to 22 carbon atoms, more preferably about 10 to 20 carbon atoms, and especially preferably about 12 to 18 carbon atoms. The aliphatic radical may be saturated or unsaturated and may be straight or branched. As in the case of the nonionic surfactants, mixtures of fatty acids can also be used such as those derived from natural sources such as tallow fatty acid, coconut fatty acid etc.

Examples of the fatty acids from which the aluminum salt stabilizers can be formed include decanoic acid, dodecanoic acid, palmitic acid, myristic acid, stearic acid, oleic acid, eicosanoic acid, tallow fatty acid, coconut fatty acid, mixtures of these acids, etc. The aluminum salts of these acids are generally commercially available and widely used. the trisic acid form, for example aluminum stearate such as aluminum tristearate Al (Cl7H35COO) 3. The monoacid salts, for example aluminum monostearate Al (OH) 2 (C17H35COO) and diacid salts 468 517 10 15 20 25 30 38 such as aluminum distearate Al (OH) (Cl7H35COO) 2 and mixtures of two or three of mono-, di- and trisic acid the aluminum salts can also be used. However, it is preferred that the tricurea aluminum salt constitutes at least 30%, preferably at least 50% and most preferably at least 80% of the total amount of aluminum fatty acid salt.

The aluminum salts are, as mentioned above, commercially available and can be easily produced by, for example, saponification of a fatty acid, eg animal fat, stearic acid, etc., followed by treatment of the resulting soap with alum, alumina, etc.

Only very small amounts of the aluminum salt stabilizer are required to achieve an improvement in physical stability.

The bleaches are generally classified as chlorine bleaches and oxygen bleaches. The chlorine bleaches are typically sodium hypochlorite (NaOCl), potassium dichloroisocyanurate (59% available chlorine) and trichloroisocyanuric acid (95% available chlorine). Oxygen bleaches are preferred and represented by percompounds which release hydrogen peroxide in solution. Preferred examples include sodium and potassium perborates, percarbonates and perphosphates, and potassium monopersulfate.

The perborates and especially sodium perborate monohydrate are especially preferred. The peracid compound is preferably used in admixture with an activator. Suitable activators that can lower the effective operating temperature of the peroxide bleach are described, for example, in U.S. Patent No. 4,264,466 or in column 1 of U.S. Patent No. 4,430,244, and the relevant portions thereof are incorporated herein by reference. Polyacetylated compounds are preferred activators, and among these, compounds such as tetraacetylethylenediamine ("TAED") and pentaacetylglycose are particularly preferred.

Other useful activators include, for example, acetylsalicylic acid derivatives, ethylidene benzoate acetate and its salts, ethylidene carboxylate acetate and its salts, alkyl and alkenyl succinic anhydride, tetraacetylglycouril ("TAGU") and their derivatives. Other useful classes of activators are described, for example, in U.S. Patent Nos. 4,118,826, 4,422,950 and 3,661,789.

The bleach activator usually interacts with the peracid compound to form a peroxyacid bleach in the wash water. Preferably, a high complexing agent sequestering agent is incorporated to inhibit any undesirable reaction between such a peroxyacid and hydrogen peroxide in the washing solution in the presence of metal ions.

Suitable sequestrants for this purpose include the sodium salts of nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DETPA), diethylenetriaminepentamethylenephosphonic acid (DTPMP) and EDPetylene quenic acid. The sequestrants can be used alone or in admixture.

In order to avoid loss of peroxide bleach, for example sodium perborate, resulting from enzyme-induced decomposition such as by catalase enzyme, the compositions may further comprise an enzyme inhibitor compound, i.e. a compound which can prevent enzyme-induced decomposition of the peroxide bleach. Suitable inhibitor compounds are described in U.S. Patent No. 3,606,990, and the relevant disclosure thereof is incorporated herein by reference.

Of particular interest as an inhibitor compound are hydroxylamine sulfate and other water-soluble hydroxylamine salts. In the preferred anhydrous compositions of the present invention, suitable amounts of the hydroxylamine salt inhibitors may be as low as about 0.01-0.4%.

In general, however, suitable amounts of enzyme inhibitors are up to about 15%, eg 0.1 to 10% by weight of the composition.

In addition to the detergent enhancers, various other detergent additives or aids may be present in the detergent product to impart this additional desired properties, of a functional or aesthetic nature. Thus, minor amounts of soil suspending or antifouling agents, such as polyvinyl alcohol, fatty amides, sodium carboxymethylcellulose and hydroxypropylmethylcellulose, may be incorporated into the formulation. A preferred antifoulant is sodium carboxymethylcellulose with a 2: 1 ratio of CM / MC, which is sold under the brand name Relatin DM 4050.

The composition containing the urea compound may also contain small amounts of an alkyl or alkylene succinic anhydride, such as octenyl succinic anhydride which acts as a viscosity controlling and anti-gelling agent. The octenyl succinic anhydride may be added in amounts of 0.5 to 10% by weight, preferably 1 to 6% by weight and more preferably 1 to 4% by weight of the composition.

Furthermore, smaller amounts of Alcosperse D107, which is sodium polyacrylate and which acts as a coating inhibitor, can be incorporated into the quaternary ammonium-containing composition. Alcosperse D107 may be incorporated in amounts of 0.5-8% by weight, preferably 2-6% by weight and more preferably 3-5% by weight of the composition.

Optical brightness enhancer for cotton, polyamide and polyester fabrics can be used. Suitable optically brightening agents include stilbene, triazole and benzidine sulfone compositions, especially sulfonated substituted triazinyl stilbene, sulfonated naphthotriazole stilbene, benzidene sulfone, etc., with stilbene and triazole combinations being most preferred. A preferred brightening agent is Stilben Brightener N4, which is a dianilinodimorpholino stilbene polysulfonate.

Enzymes, preferably proteolytic enzymes, such as subtilisin, bromelain, papain, trypsin and pepsin as well as amylase type, lipase type enzymes and mixtures thereof may be added. Preferred enzymes include protease slurry, esperase slurry and amylase. A preferred enzyme is Esperase SL8, which is a proteolytic enzyme.

Antifoams, such as silicone compounds such as Silicane L 7604, which is a polysiloxane, can be added in small effective amounts.

Bactericides, such as tetrachlorosalicylanilide and hexachlorophene, fungicides, dyes, water-dispersible pigments, preservatives, UV absorbers, antifungals, such as sodium carboxymethylcellulose, pH modifiers and pH buffers, color-safe bleaches, perfumes and dyes.

The composition may also contain small amounts of color pigments to effect coloring such as TiO 2, which is a white pigment. TiO 2 can be added in amounts of 0.1 - 4% by weight, preferably 0.1 - 2% and more preferably 0.1 - 1%.

The composition may also contain small amounts of Bentone 27 which is an organic derivative of aqueous magnesium aluminum silicate. Bentone 27 can be used in amounts of 0.2 - 3% by weight, preferably 0.5 - 2% by weight and more preferably about 1% by weight. 468 517 10 15 20 25 30 42 The composition may also contain an inorganic insoluble thickener or dispersant with a very high surface area such as finely divided silica with extremely fine particle size (eg 5 - 100 nm diameter such as that sold under the name Aerosil) or other high volume inorganic carrier materials described in U.S. Patent No. 3,630,929, in proportions of 0.1 - 10%, eg 1-5%. However, it is preferred that compositions forming peroxyacids in the wash bath (e.g., compositions containing peracid compound and activator therefor) be substantially free of such compounds and of other silicates, as it has been found that, for example, silica and silicates promote the undesired decomposition of the peroxyacid.

According to one embodiment of the invention, the stability of the builder salts in the composition during storage and the dispersibility of the composition in water can be improved by grinding and reducing the particle size of the solid builders to less than 100 μm, preferably less than 40 μm and more preferably to less than 10 μm. The solid enhancers, such as sodium tripolyphosphate (TPP), are generally provided in particle sizes of about 100, 200 or 400 microns. The liquid nonionic surfactant phase can be mixed with the solid enhancers before or after performing the grinding operation.

According to a preferred embodiment of the invention, the mixture of liquid nonionic surfactant and solid ingredients is subjected to treatment in a friction type mill in which the particle sizes of the solid ingredients are reduced to less than about 10 μm, for example to an average particle size of 2 - 10 PM or even lower (eg 1 pm). Preferably, less than about 10%, especially less than about 5%, of all suspended particles have particle sizes greater than 10 μm. Compositions whose dispersed particles are of such a small size have improved stability to separation or sedimentation during storage. Addition of the acid-terminated nonionic surfactant can lower the yield strength of such dispersions and contribute to the dispersibility of the dispersions without a corresponding decrease in the stability of the dispersions to sedimentation.

During the grinding operation, it is preferred that the proportion of solid ingredients be high enough (eg at least about 40%, such as about 50%) that the solid particles are in contact with each other and not substantially protected from each other by the nonionic surfactant liquid.

After the grinding step, any remaining liquid nonionic surfactant can be added to the ground preparation. Grinders that use grinding balls (ball grinders) or similar moving grinding elements have given very good results. Thus, one can use a batch working laboratory attritor with 8 mm diameter steatite molecules. For larger-scale working elements, such as a mill or 1 mm diameter grinder, a grinder with a diameter of 1 or 1.5 mm operates in a very small gap between a stator and a rotor operating at a relatively high speed (eg a CoBall grinder). When using such a grinder, it is desirable to first pass the mixture of nonionic surfactant and solid particles through a grinder which does not produce such a fine grind (e.g. a colloid grinder) to reduce the particle size to below 100 μm (e.g. to about 40 Pm) before the grinding step to an average particle diameter of less than about 10 Pm in the continuous ball mill.

In the preferred high performance liquid detergent compositions of the invention, typical proportions (% based on the total weight of the composition, unless otherwise indicated) of the 44 44 ingredients are as follows: Liquid nonionic surfactant detergent in the range of about 10 - 60 or 70, such as 20 - 50 or 60%, eg 30 - 40 or 50%.

Copolymer of polyacrylate and polymaleic anhydride-alkali metal salt, eg Sokalan CP5, as anti-cyst inhibitors in the range of about 0 - 10, such as 2 - 8%, eg about 3 - 5%.

Alkylene glycol monoalkyl ether as anti-gelling agent can be used together with the urea compound in an amount in the range of about 5-30, such as 5-20, eg about 5-15%.

Alkylene glycol viscosity regulating and gel inhibiting agents can be used together with the quaternary ammonium additive in an amount in the range of about 5 - 30%, such as 5 - 25%, eg about 15 - 25%. The preferred viscosity control and gel inhibiting agents are the alkylene glycol monoalkyl ethers.

Anti-precipitating agents, eg Relatin DM 4050, in the range of about 0 - 4.0 or 5.0%, preferably 0.5 - 3.0 or 4.0%, eg 1.0 - 3.0 or 0.5 - 1.5%.

Optical brightening agent in the range of about 0 - 2.0%, preferably 0.05 or 0.25 - 1.0%, eg 0.15 or 0.25 - 0.75%.

Enzymes in the range of about 0 - 3.0%, preferably 0.5 - 2.0%, eg 0.75 - 1.25%.

Perfume in the range of about 0 - 3.0%, preferably 0.10 or 0.25 - 1.25%, eg 0.25 or 0.75 - 1.0%.

Dyeing pigments in the range of about 0.1 - 4.0%, preferably 0.1 - 2.0%, and more preferably 0.1 - 1.0%. Dye in the range of about 0 - 0.10, preferably 0.0025 - 0.050, eg 0.0025 - 0.010%.

Various of the above-mentioned additives can optionally be used to achieve the desired function of the added materials.

The sedimentation inhibiting stabilizing urea-containing agent is preferably used with at least one of the viscosity regulating and gelling agents alkylene glycol monoether or acid-terminated nonionic surfactant. In some cases, benefits can be obtained by using both the alkylene glycol monoethers and the acid-terminated nonionic surfactants.

Mixtures of the acid-terminated nonionic surfactant and viscosity regulating and gel inhibiting agents, such as alkylene glycol alkyl ether anti-gel agents, may be used and in some cases benefits may be obtained by the use of such mixtures alone or with the addition of the anti-sedimentation stabilizing mixture.

In the selection of the additives, these must be selected so that they are compatible with the main constituents of the detergent composition.

In this application, as mentioned above, all proportions and percentages are expressed as the weight of the entire preparation or composition unless otherwise stated.

The concentrated anhydrous nonionic liquid detergent composition of the present invention is readily distributed in the water of the washing machine.
