Strong foaming liquid detergent compositions based on ethoxylated fatty alcohol and methods of using them to clean soiled fabrics.

The present invention relates to non-aqueous liquid compositions for the treatment of tissue. The invention relates more particularly to very foaming non-aqueous liquid detergent compositions for washing clothes, which are stable against phase separation and gelation and are capable of being easily poured, as well as the use of these compositions for] b netyage · of soiled fabrics.

Non-aqueous liquid detergent compositions for heavy laundry use are well known in the art. For example, compositions of this type can comprise a liquid nonionic surfactant in which are dispersed particles of a detergency builder, as for example are known. 25 U.S. patents Ne 4,316,812, 3,630,929 and 4,264,466, and the British patents Νβ 1,205,711, 1,270,040 and 1,600,981.

The Applicant's related French patent applications are as follows: 30 85.19510 filed on December 31, 1985; 85.04831 filed March 29, 1985; 85.05319 filed April 9, 1985.

These applications relate to non-aqueous non-ionic liquid detergent compositions for washing clothes.

Liquid detergents are often considered more convenient to use than dry powder or particulate products and consumers have therefore given them great preference. They are easy to dose, dissolve quickly in wash water and can be easily applied in 10 concentrated solutions or dispersions on soiled areas of clothes to be washed, and they do not generate dust and usually take up less space storage. Furthermore, it is possible to incorporate into the formulation of liquid detergents materials which cannot withstand drying operations without degradation, materials which it would often be desirable to employ in the manufacture of particulate detergent products. Although they enjoy many advantages over solid products in particulate or discrete units, liquid detergents are also often affected by certain inherent disadvantages which must be overcome in order to obtain commercially acceptable detergent products. Thus, some of these products do not foam easily, separate during storage, and others separate by cooling and are not easy to redisperse. In some cases, the viscosity of the product changes and it becomes either too thick to be poured or fluid enough to resemble water. Some clear products cloud and others gel on standing.

We have been interested in studying the behavior of nonionic liquid surfactant systems containing particulate matter in suspension. Particular attention was paid to non-aqueous liquid detergent compositions for washing laundry containing a detergency builder and to the problem of sedimentation of the detergency builder and other additives to the laundry in suspension, as well as to the problem of gelation which is associated with nonionic surfactants.

These considerations have an impact, for example, on the stability and dispersibility of the products and their suitability for pouring.

It is known that one of the major problems encountered with liquid detergents for washing laundry containing detergency builders is that of their physical stability. This problem stems from the fact that the density of the solid particles dispersed in the nonionic liquid surfactant is greater than the density of the liquid surfactant.

As a result, the dispersed particles tend to deposit. Two basic solutions exist for solving the problem of sedimentation: increasing the viscosity of the nonionic liquid surfactant and reducing the size of the dispersed solid particles.

It is known that the suspensions can be stabilized against sedimentation by the addition of thickeners or mineral or organic dispersants, such as for example mineral materials with very large specific surface, such as finely divided silica, clays, etc., organic thickeners such as cellulose ethers, acrylic polymers and acrylamide polymers, polyelectrolytes, etc. 35 However, such increases in viscosity * * Λ. '4 "suspensions are naturally limited by the need that the liquid suspension is easy to pour and flows easily, even at low temperatures. Furthermore, these additives do not contribute to the cleaning action of the composition.

The grinding intended to reduce the particle size offers the following advantages: 1. The specific surface of the dispersed particles increases and, consequently, the wetting of the particles by the nonaqueous vehicle (liquid nonionic surfactant) is proportionally improved. .

2. The average distance between the dispersed particles is reduced with a proportional increase in the interaction between particles.

Each of these effects contributes to increasing the resistance to gelling at rest and the flow limit of the suspension while, at the same time, grinding significantly reduces the plastic viscosity.

The flow limit is defined as the minimum stress necessary to induce plastic deformation (flow) of the suspension. Thus, by representing the suspension as a loose network of dispersed particles, if the applied stress is less than the flow limit, the suspension behaves like an elastic gel and no plastic flow occurs. As soon as the flow limit is exceeded, the network breaks at certain points and the sample begins to flow, but with a very high apparent viscosity. If the shear stress is sufficiently greater than the flow limit, the particles are particularly deflocculated by shear and the viscosity *% Λ. '5 ft apparent decreases. Finally, if the shear stress is much higher than the flow limit, the dispersed particles are totally deflocculated by shearing and the apparent viscosity is very low as if there were no interaction between the particles.

Consequently, the higher the flow limit of the suspension, the lower the apparent viscosity. The higher the shear, the better the physical stability against sedimentation of the product.

In addition to the problems of sedimentation or phase separation, non-aqueous liquid laundry detergents based on liquid non-ionic surfactants have the disadvantage that non-ionic surfactants do not readily form a stable foam and tend to to gel when added to cold water. This is a problem which is of particularly great importance in the common use of automatic household washing machines of European type where the user places the detergent composition for washing clothes in a dispensing device (for example a dispensing drawer). of the machine. During the operation of the machine, the detergent contained in the dispenser is subjected to a stream of cold water to be transferred into the main body of the washing solution. It happens in particular during the winter months, when the detergent composition and the water which feeds the dispenser are particularly cold, that the viscosity of the detergent increases sharply and that a gel forms. As a result, part of the composition is not expelled from the dispenser during the operation of the machine, and a deposit of * 6

"PF

- t composition accumulates during repeated washing cycles, which ultimately requires the user to sweep the dispenser with hot water.

The gelation phenomenon can also be a problem whenever it is desired to wash using cold water, as may be recommended for certain synthetic and delicate fabrics or for certain fabrics which may shrink in the lukewarm or hot water.

The tendency of concentrated detergent compositions to gel during storage is compounded by storage of the compositions in unheated storage rooms, or by transporting the compositions during the winter months in vehicles unheated transport.

Partial solutions to the problem of gelation of aqueous compositions substantially free of detergency builders have been proposed, for example by diluting the liquid nonionic surfactant with certain viscosity-controlling solvents and certain gelation-inhibiting agents, such as lower alkanols , for example ethyl alcohol (see US Patent No. 3,953,380), alkali metal fondates and adipates (see US Patent No. 3,368,147), hexylene glycol, polyethylene glycol, etc. , and by modification and optimization of the structure of the nonionic surfactant.

It is desired to make improvements in the production of a stable foam and in the stability and inhibition of gelation of nonaqueous liquid tissue treatment compositions.

According to the present invention, a non-aqueous, stable, highly concentrated, high-foaming liquid detergent composition is prepared for washing clothes, by adding to the composition, as the main nonionic surfactant, an alcohol. C 8 -C 8 fatty ethoxylated with 5 moles of ethylene oxide per mole of alcohol.

The compositions of the present invention contain, as an essential ingredient and as a major constituent of the total liquid nonionic surfactant of the composition, a C 8 -C 10 fatty alcohol ethoxylated with 5 moles of ethylene oxide per mole of alcohol. The nonionic surfactant (C 1 -C 6 alkyl) - (CH 2 CH 2 O) gOH of the present invention constitutes approximately 50 to 100% of the total nonionic surfactant of the composition, for example 50 to 90%, especially 50 to 75% of the total non-ionic surfactant. In order to improve the viscosity characteristics of the composition and the storage properties during storage of the composition, it is possible to add to it viscosity improving agents and anti-gelling agents such as monoalkyl ethers of alkylene glycol and anti-sedimentation agents such as an alkanolic ester of phosphoric acid. In a preferred embodiment of the invention, the detergent composition contains an alkylene glycol monoalkyl ether and an alkanolic ester of phosphoric acid as an anti-sedimentation stabilizer. Anti-gelling agents of the acid-terminated nonionic surfactant type, for example those described in patent application FR-85-04831 filed March 29, 1985, are not added to the composition since they are considered to be form with the calcium ions present in the washing liquor a calcium salt which is a foam inhibitor.

8 g 1 t

Sanitizers or bleaches and activators for these agents can be added to improve the bleaching and cleaning characteristics exhibited by the composition.

In one embodiment of the invention, the detergency builder components of the composition are ground to a particle size of less than 100 microns and preferably less than 40 microns to further improve the stability of the suspension of the components. detergency builders in non-ionic surfactant: detergent liquid.

In addition, other ingredients can be added to the composition, such as anti-fouling agents, anti-foaming agents, optical brighteners, enzymes, anti-redeposition agents, perfume and colorants.

Thus, in one of its aspects, the present invention provides a liquid detergent composition for heavy laundry work, composed of a suspension of an adjuvant detergency salt, for example of the phosphate type, in a non-surfactant. liquid ionic, the composition comprising, as the main non-ionic component, a fatty alcohol Cg-C · ^ ethoxylated with 5 moles of ethylene oxide per mole of alcohol producing a strong foam, which composition produces a strong foam, is stable against sedimentation and is easy to disperse in water.

In another aspect, the invention provides a liquid detergent composition c ο n centered for heavy laundry work, which is stable, does not settle during storage, and does not 'get 35: HF'! * * 1 9 does not gel during storage and use. The liquid compositions of the present invention are easy to pour, easy to dose and easy to put into the washing machine and are easily dispersed in water.

In another aspect, the invention provides a method for dispensing a highly foaming non-ionic liquid detergent composition for washing clothes based on (Cg-C1; L alkyl) - (CH2CH2 °) 5OH, in 10 and / or with cold water without gelation.

The use of the non-ionic surfactant with high foaming power (C 1 -C 6 alkyl) - (CH 2 CH 2 O) 5OH as the main component of the nonionic surfactant of the compositions gives a very foaming detergent composition which does not require the addition of agents. special foaming.

The concentrated non-aqueous liquid detergent compositions based on non-ionic surfactant for washing clothes according to the present invention have the advantages of being stable, of not settling during storage and of not gelling during storage . The liquid compositions are easy to pour, easy to dose and easy to introduce into washing machines and are easily dispersed in water.

An object of the present invention is to provide a liquid, non-aqueous, non-aqueous, stable and very foaming detergent composition for heavy-duty work, containing an anti-sedimentation stabilizing agent and an anionic detergency adjuvant salt of the phosphate type in suspension in a nonionic surfactant. .

Another object of the invention is to provide very foaming liquid tissue treatment compositions which are suspensions of mineral particles insoluble in a non-aqueous liquid and which are stable on storage. easy to pour and disperse in cold, lukewarm or hot water.

Another object of the invention is to formulate S non-aqueous, highly foaming liquid detergent compositions based on nonionic surfactants and reinforced with a detergency builder, for heavy laundry work, which can be poured at any temperature and which can be dispersed 10 times from the dispenser device of automatic European type washing machines without clogging or obstructing the dispenser even during the winter months.

A particular aim of the present invention is to provide non-aqueous liquid nonionic detergent compositions containing a detergency builder, for heavy laundry work, provides stable, non-gelling and very foaming suspensions and contain as main constituent of the total nonionic surfactant, a nonionic surfactant (Cg-Cj ^ -iCl ^ Cl ^ OJgOH alkyl.

These and other objects of the invention will become more apparent from the following detailed description of its preferred embodiments and are generally achieved by preparing a detergent composition by adding to the non-aqueous liquid nonionic surfactant a non-ionic surfactant with high foaming power (C 1 -C 8 alkyl) - (CH 2 CH 2 O) 50H, the said composition comprising mineral or organic additives for treating the tissues, for example agents for improving viscosity and one or more anti-gelling agents, anti-scaling agents, pH adjusting agents; bleaches, bleach activators, defoamers, βρ * ^ i! * ’There optical brighteners,. enzymes, anti-deposition agents, perfume and dyes.

According to the present invention, the foaming properties of the non-aqueous nonionic liquid detergent composition for washing clothes are substantially. improved by adding a nonionic surfactant (Cg-C11 alkyl Kch2ch2o) 5oh to the composition.

The addition of the nonionic surfactant (10 Cg-C11 alkyl) - ^ H2CH20) gOH as the main constituent of the total nonionic surfactant of the composition significantly improves the. foaming properties of the composition. The compositions of the present invention contain, as an essential ingredient) (Cg-C11 alkyl) - (CH2CH20) 50H as the main constituent of the total nonionic surfactant of the composition.

The nonionic surfactant (C alkyl-C alkyl alkyl) - (CH2CH2O) 5OH is available from Shell Chemical Company, Inc. under the trademark Dobanol 9i- 5.

Non-ionic detergent surfactant

Non-ionic synthetic organic detergents which can be used in small amounts in the practice of the invention can be any of a wide variety of known compounds.

As is well known, non-ionic synthetic organic detergents are characterized by the presence of a hydrophobic organic group and a hydrophilic organic group and they are typically produced by the condensation of an aliphatic or alkyl-aromatic hydrophobic organic compound with ethylene oxide (hydrophilic in nature). Almost any compound

.V

"F

. Wh! , 12 hydrophobic carrying a carboxy, hydroxy, amido or amino group with a labile hydrogen atom attached to nitrogen can be condensed with ethylene oxide or with its polyhydration product, polyethylene-5 glycol, to form non-ionic detergent. The length of the polyoxyethylene hydrophilic chain can be easily adjusted to achieve the desired ratio between the hydrophobic and hydrophilic groups. Typical suitable nonionic surfactants are those described in U.S. patents. N * 4,316,812 and 3,630,929.

Generally, nonionic detergents are lipophilic compounds polyalkoxylated by lower alkoxy groups in which the desired hydrophilic-lipophilic ratio is obtained by adding a hydrophilic poly (lower alkoxy) group to a lipophilic moiety. A preferred class of the nonionic detergent used is that of the higher alkanols polyalkoxylated by lower alkoxy groups or the alkariol having from 9 to 8 carbon atoms and or the number of moles of lower alkylene oxide (to 2 or 3 carbon atoms) is from 3 to 12. Among these materials, it is preferable to use those in which the higher alkanol is a higher fatty alcohol having 9 to 11 or 12 to 15 carbon atoms which contain 5 to 8 or 5 to 9 lower alkoxy groups per mole. Preferably, the lower alkoxy group is the ethoxy group, but in some cases it can, advantageously be mixed with the propoxy group if present, often only constitutes a minor (less than 50%) pxpxtiai.

Representative 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 molecule, for example Neodol 25-7 and Neodol 23-6.5 which are products manufactured by î 13

Shell Chemical company, Inc. The former is a condensation product of a mixture of higher fatty alcohols having on average about 12 to 15 carbon atoms, with about 7 moles of ethylene oxide, and the latter is a corresponding mixture where the number of carbon atoms of the higher fatty alcohol is from 12 to 13 and the number of ethylene oxide groups present is on average about 6.5. Higher alcohols are primary alkanols.

Other examples of such detergents include

Tergitol 15-S-7 and Tergitol-15-s-9. both of which are secondary linear alcohol ethoxylates produced by Union Carbide Corp. The first is the mixed ethoxylation product of a secondary linear alkanol of 11 to 15 carbon atoms with seven moles of ethylene oxide and the second is a similar product but where nine moles of ethylene oxide have reacted.

Higher molecular weight nonionic surfactants are also useful in the present invention as components of nonionic detergent, such as Neodol 45-11, which are similar condensation products of ethylene oxide on higher fatty alcohols, the higher fatty alcohol having 14 to 15 carbon atoms and the number of ethylene oxide groups being approximately 11 per molecule. These products are also manufactured by Shell Chemical Company.

Other useful nonionic surfactants are represented by the class of commercially known nonionic surfactants which are sold under the trademark Plurafac. Plurafac series surfactants are the reaction products of a higher linear alcohol and a mixture of ethylene oxide and propylene, containing a 14 F chain.

mixed ethylene oxide and propylene oxide, terminated by a hydroxyl group. Examples are the products (A) a C13-C15 fatty alcohol condensed with 6 moles of ethylene oxide and 3 moles of propylene oxide, (B) a C13-C15 fatty alcohol condensed with, 7 moles of propylene oxide and 4 moles of ethylene oxide, (C) a C13-C15 fatty alcohol condensed with 5 moles of propylene oxide and 10 moles of ethylene oxide, (D) a mixture 1: 1 of 10 products (B) and (C).

Another class of liquid nonionic surfactants is commercially available from Shell Chemical Company, Inc. under the trademark Dobanol, for example Dobanol 25-7 which is a C12-C15 ethoxylated fatty alcohol with an average of 7 moles of ethylene oxide, per mole of fatty alcohol.

Another useful class of non-ionic surfactants is the series of products called "Surfactant T" available from the company British Petroleum. The nonionic surfactants Surfactant T are obtained by ethoxylation of C13 secondary fatty alcohols having a narrow distribution of ethylene oxide contents. Surfactant T5 contains an average of 5 moles of ethylene oxide? Surfactant T7 contains on average 7 moles of ethylene oxide? Surfactant T9 contains an average of 9 moles of ethylene oxide and Surfactant T12 contains an average of 12 moles of ethylene oxide, per mole of C13 secondary fatty alcohol.

In the compositions of the present invention, useful nonionic surfactants include C12-C15 secondary fatty alcohols with relatively narrow ethylene oxide contents, ranging from about 7 to 9 moles, and alcohols. r.

fatty Cg-C ^ ethoxylated with about 5 to 6 moles of ethylene oxide.

Mixtures of two or more of the liquid nonionic surfactants can be used with the surfactant (C 1 -C 6 -alkyl-CH 2 O 4 CHgO) of the present invention and in some cases can be drawn

advantages of using such mixtures.

ADJUVANT DETERGENCE SALTS

The nonaqueous liquid nonionic surfactant used in the compositions of the present invention contains, in the dispersed and suspended state, fine particles of organic and / or mineral detergency builder salts.

The detergent compositions of the invention include adjuvant water soluble and / or water insoluble detergency salts. Alkaline mineral water-soluble detergent builders which can be used alone with the detergent compound or in admixture with other detergency builders are alkali metal carbonates, bicarbonates, borates, phosphates, polyphosphates and silicates (ammonium or substituted ammonium salts can also be used). Particular examples of these salts are sodium tripolyphosphate, sodium carbonate, sodium tetraborate, sodium pyrophosphate, potassium pyrophosphate, sodium bicarbonate, potassium tripolyphosphate, sodium hexametaphosphate, sodium sesquicarbonate, sodium mono- and di-orthophosphates and potassium bicarbonate. Sodium tripolyphosphate (TPP) is particularly preferred.

Since the compositions of the present invention are generally very concentrated and therefore can be used in doses doses. ,: i. ; y relatively low, it is desirable to supplement any phosphate-type detergency builder (such as sodium tripolyphosphate) with an auxiliary detergency builder such as a lower polycarboxylic acid or a polymeric carboxylic acid having a large capacity of calcium fixation in order to inhibit the incrustation which, otherwise, could be caused by the formation of an insoluble calcium phosphate.

Suitable lower polycarboxylic acids include the alkali metal salts of lower polycarboxylic acids, preferably the sodium and potassium salts. Suitable lower polycarboxylic acids have two to four carboxylic acid groups. The preferred sodium and potassium salts of lower polycarboxylic acids are the citric and tartaric acid salts.

The sodium salts of citric acid are the most preferred, especially trisodium citrate. You can also use monosodium and disodium citrates. it is also possible to use the monosodium and disodium salts of tartaric acid. Are alkali metal salts of lower polycarboxylic acids particularly good detergency builder salts? thanks to their strong capacity for fixing calcium and magnesium, they inhibit incrustation which could, without them, be caused by the formation of insoluble salts of calcium and magnesium.

Other organic detergency builders are polymers and copolymers of polyacrylic acid and polymaleic anhydride and their alkali metal salts; More particularly, these detergency builder salts can consist of a copolymer which F.

! 17 is the product of the reaction of an approximately equal number of moles of methacrylic acid and maleic anhydride, having been completely neutralized to form its sodium salt. This detergency builder 5 is commercially available under the trademark Spkalan CP5. This detergency builder is used, even when used in small amounts, to inhibit encrustation.

Examples of sequestering alkaline organic detergency builder salts which may be used with the detergency builder salts or in admixture with other organic and inorganic detergency builders are alkali metal, ammonium and ammonium aminopolycarboxylates Substituted, for example, sodium and potassium ethylenediaminetetraacetate (EDTA), sodium and potassium nitriloacetates (NTA) and triethanolamine N- (2-hydroxyethyl) nitrilodiacetates.

Mixtures of these aminopolycarboxylates are also suitable.

Other suitable detergency builders of the organic type include carboxymethyl succinates, tartronates and glycolates. Polyacetal carboxylates are of particular interest. Polyacetal carboxylates and their use in detergent compositions are described in patent application FR-86 11 852 of the Applicant filed on August 19, 1986, and in patents of the E.U.A. ne 4.1. 44.226, 4.315.092 and 4.146 30 495. The alkali metal silicates are useful detergency builder salts which also act by adjusting or regulating the pH and rendering the composition anticorrosive towards the parts of the washing machine. Sodium silicates, the Na2 O / SiC ^ ratios of which range from 1.6 / 1 to 1 / 3.2, in particular about 35 1/2 to 1 / 2.8, are preferred. Potassium silicates of mime ratios can also be used.

ψ. ..

! Other typical suitable detergency builders include, for example, those described in U.S. patents. Ne 4,316,812, 4,264,466 and 3,630,929. The mineral 5 detergency builder salts can be used with the nonionic surfactant detergent or in admixture with other organic or mineral detergency builder salts.

It is also possible to use crystalline and amorphous aluminosilicates insoluble in water of the zeolite type. The zeolites correspond to the general formula: (M20) x. (Al203) y. (Si02) z.wH20 in which x is 1, y ranges from 0.8 to 1.2 and is preferably 1, z ranges from 1 , 5 to 3.5 or more and preferably 2 to 3, w is 0 to 9 and preferably 2.5 to 6, and M is preferably sodium. A typical zeolite is a zeolite of type A or of similar structure, type 4A being particularly preferred. Preferred aluminosilicates have calcium ion exchange capacities of about 200 milliequivalents per gram or more, for example 400 meq / g.

Various crystalline zeolites (i.e., aluminosilicates) which can be used are described in British Patent Ne 1,504,168, the U.S. Patent. No. 4,409,136 and Canadian patents Νβ 1,072,835 and 1,087,477. An example of the amorphous zeolites useful here can be found in Belgian patent No. 835 351.

Other materials such as clays, particularly water-insoluble types, may be useful auxiliaries in the compositions of the present invention. Bentonite is particularly useful. This material consists mainly of montmorillonite which is a 19 W silicate ...

hydrated aluminum of which about one sixth of the aluminum atoms can be replaced by magnesium atoms and with which various amounts of hydrogen, sodium, potassium, calcium, etc. can be weakly combined. Bentonite, in its purest form (that is to say free from any sand, abrasive particles, etc.) suitable for detergents, contains at least 50% of montmorillonite and therefore its capacity for exchange of cations is 10 of at least about 50 to 75 meq per 100 g of bentonite. Particularly preferred bentonites are bentonites from the western U.S.A. or from Wyoming, which have been sold under the designations Thixo-jels 1, 2, 3 and 4 by Georgia Kaolin Co. These 15 bentonites are known to soften textiles as described in British patents Ne 401 413 and 461 221.

Viscosity Control and Antialipification Agents The preservative properties of the detergent composition in storage can be significantly improved by incorporating into the composition an effective amount of low molecular weight amphiphilic compounds which act as regulating agents viscosity and inhibiting gelation towards the nonionic surfactant. Viscosity control and anti-gelling agents work to lower the temperature at which the non-ionic surfactant forms a gel when added to water. These viscosity adjusting and anti-gelling agents may be, for example, amphiphilic compounds of the lower monoalkyl ether type of low molecular weight alkylene oxide. Amphiphilic compounds can be considered analogous in their chemical structure to liquid nonionic surfactants of the 20 type type.

ethoxylated and / or propoxylated fatty alcohol, but they have relatively short hydrocarbon chains (C2 to Cg) and a relatively low content of ethylene oxide (approximately 2 to 6 ethylene oxide groups per molecule).

Suitable amphiphilic compounds are represented by the following general formula: R2

R10 (CH CH20) nH

10 2 in which R1 is a C2-Ca alkyl group R is 1. * hydrogen or a methyl group and n is a newborn of about 1 to 6 parts.

In particular, these compounds are lower monoalkyl ethers (C2 to C5) of lower alkylene glycol (C2 to C3).

More particularly, these compounds are ethers of lower monoalkyl (C ^ to C5) of mono-, di- or trialkylene-lower glycol (C2 to C3).

Particular examples of suitable amphiphilic compounds include the following: ethylene glycol monoethyl ether (C2H5-0-CH2CH2OH), diethylene glycol monobutyl ether (C4H9-0- (CH2CH20) 2H), tetraethylene glycol monobutyl ether ( C4H7-0- (CH2CH20) 4H), and dipropylene glycol monomethyl ether (CH3-o- (CH CHO) 2H).

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

The compositions of the present invention have high foaming properties with improved viscosity and stability characteristics and remain stable and suitable for pouring at temperatures as low as about 5 ° C or less.

In one embodiment of the present invention, a small amount of a stabilizing agent which is an alkanolic ester of phosphoric acid may be added to the formulation.

Improvements in the stability of the composition can be brought about by the incorporation of a small effective amount of an organic acidic phosphorus compound carrying an acid group -POH, for example a partial ester of phosphorous acid and a alkanol. As described in Applicant's patent application 85.05319 filed April 9, 1985, the acidic organic compound of phosphorus carrying an acid group -POH can increase the stability of the suspension of detergency builders in the non-aqueous liquid nonionic surfactant . The acidic organic phosphorus compound can be, for example, a partial ester of phosphoric acid and an alcohol such as an alkanol having a lipophilic character in that it has, for example, more than 5 carbon atoms , for example 8 to 20 carbon atoms.

A particular example is a partial ester of phosphoric acid and a C 16 -C 18 alkanol.

f 22 (Empiphos 5632 de Marchon); this product consists of approximately 35% monoester and 65% diester.

The incorporation of very small quantities, for example 0.3% by weight, of the acidic organic phosphorus compound makes the suspension stable against sedimentation at rest while leaving it capable of being poured, however only at low concentrations of stabilizing agent, its plastic viscosity generally decreases. Addition of more than about 0.3%, e.g., about 1.0% or more, should be avoided, as it would be expected that a higher concentration of organic phosphorous ester would inhibit foaming. .

Bleaching Agents - | _5 Bleaching agents are broadly divided, for convenience, into chlorine bleaching agents and oxygen bleaching agents. Chlorine bleaches are typically represented by sodium hypochlorite (NaOCl), potassium dichloroisocyanurate (59% active chlorine) and trichloroisocyanuric acid (95% active chlorine). Oxygen bleaches are preferred and are represented by per-compounds which release hydrogen peroxide in solution. Preferred examples include sodium and potassium perborates, percarbonates and perphosphates, and potassium monopersulfate. Perborates, especially sodium perborate monohydrate, are particularly preferred.

The peroxygen compound is preferably used in admixture with an activator for this compound. Suitable activators which can lower the effective action temperature of the peroxidized bleach are described, for example, in the U.S. Patent. Ne 4 264 466, or in column 1 r.

! 23 of the U.S. Patent No. 4,430,244. Are polyacylated compounds preferred activators? among these, compounds such as tetraacetyl ethylenediamine (TAED) and pentaacetylglucose are particularly preferred.

Other useful activators include, for example, acetylsalicylic acid derivatives, ethylidene benzoate acetate and its salts, ethylidene acetate carboxylate and its salts, an alkyl or alkenyl succinic anhydride, tetraacetylglycourile (TAGU), and derivatives of these activators. Other useful classes of activators are described, for example, in U.S. patents. N * 4,111,826, 4,422,950 and 3,661,789.

The bleach activator usually interacts with the peroxygen compound to form a bleaching peroxyacid in the wash water. It is preferable to incorporate a sequestering agent of high complexing power in order to inhibit any undesirable reaction between this peroxyacid and hydrogen peroxide in the washing solution in the presence of metal ions.

Suitable sequestering agents include the sodium salts of nitrilotriacetic acid (NTA), ethylenediamine tetraacetic acid (EDTA), diethylenetriamine-pentaacetic acid (DEPTA), diethylenetriaminepen-tamethylenephosphonic acid (DTPMP) sold under the trademark Dequest 2066, and ethylene-diaminetetramethylenephosphonic acid (EDITEMPA). The sequestering agents can be used alone or as a mixture.

In order to avoid loss of the bleaching peroxide, for example sodium perborate, as a result of an enzymatic decomposition, for example 24 r., Under the effect of a catalase type enzyme, the compositions may contain additionally an enzyme inhibitor compound, i.e. a compound capable of inhibiting the enzymatic decomposition of bleaching peroxide. Suitable inhibitors are described in the patent des Ό.Ό.Α. N® 3,606,990.

As particularly useful inhibitory compounds, mention may be made of hydroxylamine sulfate and other water-soluble salts of hydroxyamine. In the preferred nonaqueous compositions of the present invention, suitable proportions of inhibitory hydroxylamine salts may be as low as about 0.01-0.4%. In general, however, suitable proportions of enzyme inhibitors are up to about 15%, for example 0.1-10%, based on the weight of the composition.

In addition to detergency builders, various other additives or builders may be present in the detergent product to provide it with additional desired properties, whether functional or aesthetic in nature. Thus, minor amounts of soil repellency or suspending agents may be included in the formulation, for example polyvinyl alcohol, fatty amides, sodium carboxymethyl cellulose, hydroxypropyl methyl cellulose. A preferred anti-redeposition agent is a sodium carboxymethyl cellulose having a CM / CMC ratio of 2: 1, which is sold under the trademark Relatin DH 4050.

It is also possible to incorporate into the composition small quantities of Duet 787 which is a perfume and which is supplied by International Flavors and Fragrances, Inc. Union Beach, NJ 07735 (USA). Duet 787 can be added in proportions of, for example 0 35 to 3, preferably 0.2 to 3 percent, for example 0.5 to 25 to 2 percent, especially 0.3 to 1.5 percent by weight of the composition.

Optical brighteners for cotton, polyamide and polyester fabrics can be used. Suitable optical brighteners include stilbene, triazole and benzidine sulfonated compositions, including sulfonated substituted triazinyl-stilbene, sulfonated naphtotriazole-stilbene, benzidine sulfone, etc., the most preferred being combinations of stilbene and of triazole. A preferred brightener is Stilbene Brightener N4 which is a dimorpholino-dianilino-stilbene sulfonate.

Enzymes may be used, preferably proteolytic enzymes, such as subtilisin, bromelain, papain, trypsin and pepsin, as well as amylase-like enzymes, lipase-like enzymes and mixtures thereof. Preferred enzymes include a protease suspension, an esperase suspension and an amylase. A preferred enzyme is Esperase SL8 which is a proteolytic enzyme. Antifoaming agents, for example silicon compounds such as Silicane L 7604, can also be added in small effective amounts.

It is also possible to use bactericides, for example tetrachlorosalicylanilide and hexachlorophen, fungicides, dyes, pigments (dispersible in water), preservatives, ultraviolet absorbers, anti-yellowing agents such as sodium carboxymethyl cellulose, pH modifiers and pH buffers, color preserving bleaches, perfume and coloring agents and brightening agents such as ultramarine blue.

In one embodiment of the invention, the stability of the adjuvant detergency salts in the composition during storage and the dispersibility of the composition in water are improved by grinding and reduction of the particle size of the adjuvants, solid detergents less than 100 microns, preferably less than 40 microns and more preferably less than 10 microns. Solid detergency builders, for example tripolyphosphate. sodium (TPP), are generally supplied in particle sizes of about 100, 200 or 400 micrometers. The liquid nonionic surfactant phase can be mixed with the solid detergency builders before or after performing the grinding operation.

In a preferred embodiment of the invention, the mixture of liquid nonionic surfactant and solid ingredients is subjected to the action of an attrition type mill in which the particle sizes of the solid ingredients are reduced unless about 10 micrometers, for example at an average particle size of 2 to 10 micrometers or even less (for example 1 micrometer). Preferably, less than about 10%, and in particular less than about 5%, of all the particles in suspension have dimensions greater than 10 micrometers. Compositions with dispersed particles of such small dimensions exhibit better stability against separation or sedimentation during storage. The addition of the acid-terminated nonionic surfactant can decrease the flow limit of these dispersions and improve their dispersibility without causing a correlative reduction in the stability of the dispersions against sedimentation.

In the grinding operation, it is preferable that the proportion of solid ingredients is high enough (for example at least about 40%, such as about 50%) so that the solid particles are in contact with each other and are not substantially isolated from each other by the liquid nonionic surfactant. After the milling step, any remaining liquid nonionic surfactant can be added to the milled composition. Grinders which employ grinding balls (ball mills) or similar movable grinding elements have given very good results. Thus, one can use a laboratory mill-attritor working in portions containing grinding balls in steatite of 8 mm in diameter. For a larger scale operation, a mill operating in continuous mode can be used in which there are grinding balls of 1 mm or 1.5 mm in diameter working in a very small gap between a stator and a rotating rotor. at a relatively high speed (for example a CoBall mill); when using such a mill, it is advantageous to first pass the mixture of nonionic surfactant and solid ingredients through a mill which does not perform such a fine milling (e.g. a colloid mill) in order to reduce the particle size to less than 100 micrometers (for example to about 40 micrometers) before the grinding step to an average particle diameter of less than about 10 micrometers which takes place in the ball mill operating in continuous mode.
