Description

DETERGENT COMPOSITIONS FOR HANDWASHING CLOTHES CONTAINING A COMBINATION OF SURFACTANT AGENTS TECHNICAL FIELD The present invention involves detergent compositions for laundry by hand washing or hand washing with the aid of a machine that contains a certain mixture of surfactants.

BACKGROUND OF THE INVENTION Around the world, many people clean fabrics by washing by hand or washing by hand with machine aid with compositions containing soap and / or detergent. Manual washing with the help of a machine involves the use of a machine for manual or semi-automatic washing with the completion of the washing process by washing by hand. Of many geographical locations where hand washing is common, the water hardness of calcium and magnesium ions can be as high as 25 g / 3,785 1 as CaC 3 equivalent, or higher. In such conditions of high hardness, the laundry detergent improving capacity can be exhausted to sequester all hardness. In this condition, conventional surfactant systems have their cleaning performance capability or at least their cleaning performance is substantially less than conditions from which the improver system can substantially subtract all hardness. In addition, laundry detergent compositions are preferably formulated to provide a cleansing, including adequate cleansing on greasy stains and dirt on the body, while remaining benign to the skin of the hands. In general, there is a need to improve the cleanliness of these soils while maintaining good health on the hands. The effective detergent compositions for hand washing contain anionic surfactants, particularly alkylbenzene sulphonate and alkyl sulfate surfactants. It has also been considered beneficial for the appearance and cleaning of cotton fabrics for detergents for hand washing clothes containing an amount of a cellulase enzyme sufficient to improve the appearance and cleanliness of such fabrics, particularly after multiple cleaning cycles. However, it is known that the presence of anionic surfactants can inhibit the activity of the cellulase enzymes, thus reducing the effectiveness of the cellulase to provide the improvements of aparaciencia and cleaning. European Patent Application 0,051,986 (The Procter &Gamble Company) discloses a composition A granular detergent containing mixtures of anionic surfactant, preferably alkylbenzene sulfonate and alkyl sulfate, and mixtures thereof with soap, an alkoxylated nonionic surfactant and water soluble cationic surfactants. It is an object of the present invention to provide a laundry detergent composition that provides superior cleaning performance in operations for hand washing or hand washing laundry with the aid of a machine. Another object of the present invention is to provide a surfactant for a detergent composition which can maintain good cleaning performance under high hardness conditions even after the detergent builder capacity of the laundry detergent composition has been stressed or depleted. Sequester the hardness in the wash water. It is a further object to provide a detergent composition for hand washing that provides improved cleaning performance on greasy and body soils without diminishing the softness of the product on the hands. It is still another object of the present invention to provide a kinetic surfactant system containing an alkylbenzene sulfonate surfactant which minimizes interference with the activity of the cellulase enzymes towards the cellulosic web substrate. It is another object to provide the aforementioned benefits while maintaining good foaming on the detergent composition during hand washing.

The alkyl alcohol ethoxylation surfactants have a "degree of ethoxylation" (number of ethoxy moieties per molecule) which can be widely distributed because, when an alkyl alcohol is ethoxylated from the starting material with ethylene oxide, an extensive distribution of the number of ethoxy moieties per molecule. For AE surfactants, the degree of ethoxylation is, on average, from about 1 to about 10, preferably from about 3 to about 9, more preferably from about 5 to about 8, especially about 7. The surfactant system of the present compositions preferably includes only, or substantially only, the surfactants disclosed hereinabove, such that the surfactant system of the present compositions consists, or consists essentially, of alkylbenzenesulfonate and / or alkyl sulfate surfactants (more preferably surfactants) of alkylbenzenesulfonate) AES surfactants, HAQA surfactants, and AE surfactants. However, minor amounts of other auxiliary surfactants may also be used, including anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and zwitterionic surfactants, provided they do not significantly interfere with the benefits of the surfactant system. Such auxiliary surfactants may include C 1 -C 18 alkylalkoxycarboxylates (especially the ethoxycarboxylates of 1-5) glycerol ethers of C 1 or 18'alkyl polyglycosides of C 1 or -18 ^ their corresponding sulfated polyglycosides, alpha fatty acid ethers -sulfonated C ^ -C ^ ß- Such auxiliary surfactants may include one or more Cg-C] _2 alkylphenollalkoxylates (especially mixed ethoxylates and ethoxylates / propoxylates, betaines and sulphobetaines (sultans) of C ^ -C ^ s and oxides of C.sub.1 -Cis.sup.-Ta.les auxiliary surfactants may include N-alkyl polyhydroxy fatty acids amides of C ^ -c18 'such as N-methyl glucamides of cl2_c18 (see PCT application WO 92/06154); Other surfactants derived from sugars include N-alkoxy polyhydroxy fatty acid amides, such as N- (3-methoxypropyl) glucamide of ^ 10-18- Conventional fatty acid soaps of C] _Q-C2O are also possible surfactants auxiliary Such auxiliary surfactants, if present, may be included at levels up to a total of about 10%, preferably about 0.5-3%. In addition, a hydrotrope or a mixture of hydrotropes may be present in the present compositions. Preferred hydrotropes include the alkali metal, preferably sodium, toluene sulfonate salts, xylene sulfonate, cumene sulfonate, sulfosuccinate and mixtures thereof. Preferably, the hydrotrope, either acidic or in the salt form, and being substantially anhydrous, is added to the linear alkylbenzenesulfonic acid before neutralization. The hydrotrope, if present, is preferably from about 0.5% to about 5% of the present compositions. Although it is known that a LAS surfactant will sequester and be precipitated from a wash solution by divalent metal ions, such as calcium, under conditions of high water hardness, it has been found that the presence of the HAQA cationic surfactant it also causes a greater proportion of the LAS surfactant to precipitate. The precipitation of LAS in conditions of high hardness reduces the cleaning power of the detergent composition, since the precipitated LAS is available for the cleaning function. The use of low levels of AES surfactant, at the proportions described herein, in a surfactant system also containing the surfactant The primary anionic and cationic surface active agent of HAQA, substantially reduces the tendency of the anionic surfactant, notably LAS, to precipitation by the interaction with divalent cations under conditions of high hardness of the wash water and inferiorly improved washing. In Generally speaking, for washing conditions of high hardness, washing solutions having approximately 16 grains per 3,785 1 (gpg) or more of divalent metal ions (such as calcium, magnesium and others) expressed in terms of CaC 3 equivalent and more preferably about 25 gpg or more. Such conditions are common in many countries and are particularly uncomfortable for washing performance under hand washing conditions.

Other components The compositions of the present invention contain from about 60% to about 95%, preferably from about 65% to about 90%, more preferably from about 70% to about 85%, more preferably still from about 75% to about 80%, of other components, commonly used in laundry detergent products. A typical state of the classes and species of other surfactants, detergency builders of other ingredients that may be included in the present compositions appear in the U.S.A. No. 3,664,961, issued to Norris on May 23, 1972, incorporated herein by reference, and EP 550,652, published April 16, 1992. The following are representative of such materials, but are not intended to be limiting.

I Detergency Speakers The compositions of the present invention preferably contain builders that help control mineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in fabric washing compositions to aid in the removal of particulate soils. The level of builder can vary widely depending on the final use of the composition and its desired physical form. When present, the compositions will typically contain at least about 1% builder. Granular formulations typically contain from about 10% to about 80%, more typically from about 15% to about 50% by weight, of builder. It is not intended, however, to exclude lower or higher levels of detergency builder. Although detergent compositions are typically formulated to thoroughly clean all washing conditions, the detergent composition of the present invention, like any detergent, can often be used under washing conditions using a wash water having high hardness and which can be a much higher hardness of the ability of the builder system to sequester and control. When the hardness of the wash water is close to the detergent builder's capacity of the detergent composition or exceeds it, resulting in a lower improved wash condition, the hardness of the non-sequestered water may interfere with the cleaning performance of the agent alkylbenzenesulfonate surfactant. Specifically, the alkylbenzenesulfonate surfactant can act as a sequestering agent for the non-sequestered hardness (specifically calcium ions). The sequestration of the hardness interferes with the yield of the alkylbenzene sulfonate as a cleaning surfactant. The improved surfactant system of the present invention uses a low level of AES surfactant to interfere with the sequestration of calcium ions by the alkylbenzene sulfonate. Therefore, the low levels of AES according to the present invention maintains a good cleaning performance of the alkylbenzene sulfonate surfactant even under the lower improved washing conditions. Inorganic detergent builders containing phosphate include, but are not limited to, alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by tripolyphosphates, pyrophosphates and vitreous polymeric metaphosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarburates) and aluminosilicates. Detergency builders are required in some places. Importantly, the present compositions work surprisingly well even in the presence of so-called "weak" builders (as compared to phosphates) such as citrate or the so-called "inferiorly improved" situation which can occur with the zeolite builders. of silicate stratified, or with low levels of detergency builders containing P. In situations where phosphorus-based builders can be used, the various alkali metal sulfates, such as the well-known sodium tripolyphosphates, can be used. (STPP), sodium pyrophosphate and sodium orthophosphate. Phosphonate builders, such as ethane-1-hydroxy-1, 1-diphosphonate and other known phosphonates can also be used (see, for example, U.S. Patents 3,159,581.; 3,213,030, 3,422,021; 3,400,148 and 3,422,137). Examples of silicate builders are alkali metal silicates, particularly those having a Si? 2: Na2? Ratio. in the range of from about 1.6: 1 to about 3.2: 1, preferably and about 1.6: 1; and stratified silicates, such as the layered sodium silicates described in the U.S.A. 4,664,839, issued May 12, 1987 to Rieck. Other silicates may also be useful, such as, for example, magnesium silicate, which can serve as a chilling agent in the granular formulations, and stabilizing agent for the oxygen bleach and component of the foam control systems. Examples of carbonate builders are carbonates and alkali metal bicarbonates disclosed in German Patent Application No. 2,321,001 published November 15, 1973. Sodium carbonate is preferred. Aluminosilicate builders are useful in the present compositions. Aluminosilicate builders are of great importance in many granular detergent compositions currently sold. The aluminosilicate builders include those that have the empirical formula: Mz (ZAIO2) and. VH2O where z and y are integers with a value of at least 6, and the molar ratio of zay are in the range of 1.0 to about 0.5 and v is an integer of about 15 to about 264. Useful materials of aluminosilicate ion exchange are obtainable commercially. These aluminosilicates can be of crystalline or amorphous structure and can be aluminosilicates present in nature or synthetically derived. A method for producing aluminosilicate ion exchange materials is disclosed in the U.S.A. 3,985,669, Krummel et al., Issued October 12, 1976. Preferred crystalline aluminosilicate ion exchange synthetic materials, useful herein, are obtainable with the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite. X. In an especially preferred embodiment, the ionic exchange material of crystalline aluminosilicate has the formula: Na ^ 2 ((AIO2) 12 (SÍO2) 12). H20 wherein v is from about 20 to about 30, especially about 27. This material is known as Zeolite A. Dehydrated zeolites can also be used (v = about 0-10). Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter. Organic builders suitable for the present compositions include, but are not restricted to, a plurality of polycarboxylate compounds. As used herein, "polycarboxylates" refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builders can generally be added to the compositions in acid form, but can also be added in the form of neutralized salts. When used in the salt form, alkali metals, such as sodium, potassium and lithium salt, or ammonium alkanol are preferred. Citrate builders, for example, citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders obtained from renewable sources and are biodegradable. Citrates can be used in granular compositions, especially in combination with zeolite builders and / or layered silicate. Oxydisuccinates are also useful in such compositions and combinations. Also suitable in the present detergent compositions are the 3, 3-dicarboxy-4-oxa-1, 6-hexanedioa and the related compounds disclosed in the U.S. Pat. No. 4,566,984, Bush, issued January 28, 1986. Useful succinic acid builders include alkanoyl and alkanyl succinic acids of C5_20 and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: lauryl succinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred) 2-pentadecenylsuccinate, and the like. Lauryl succinates are the preferred builders of this group and are described in European Patent Application 200 263, published on November 5, 1986. Other suitable polycarboxylates are disclosed in the U.S. patent. 4,144,226, Crutchfield, et al., Issued March 13, 1979 and in the U.S. patent. 3,308,067, Diehl, issued March 7, 1967. See also U.S. Pat. 3,723,322 to Diehl. Fatty acid compositions, for example, non-monocarboxylic acids of Ci.sub.2.sub.3] .sub.8 alone or in combination with the predicted builders, especially the citrate and / or succinate builders, can be incorporated to provide improved activity. additional detergency speaker. Such use of fatty acids will generally result in a decrease in foaming, which should be taken into account by the formulator. The compositions of the present invention contain from 0% to about 60% builders, preferably from about 10% to about 60%, more preferably from about 13% to about 40%, more preferably from about 20% to about approximately 37%. The compositions preferably contain from about 5% to about 45% of builders different from carbonates (including bicarbonates) and silicates (excluding zeolites), preferably selected from the inorganic phosphate builder and zeolite (more preferably from builders) inorganic phosphate detergent), more preferably from about 14% to about 40%, more preferably still from about 18% to about 36%; STPP is preferred among such builders. The present compositions preferably also contain from about 5% to about 19% sodium carbonate, more preferably from about 7% to about 15%, more preferably still from about 9% to about 13%. The present compositions preferably also contain from about 5% to about 12% silicates, more preferably from about 6% to about 10%, and more preferably still from about 7% to about 8%.

AGENTS OUELATADORES The present detergent compositions may also optionally contain one or more iron and / or manganese chelating agents. Such chelating agents can be selected from the group consisting of aminocarboxylates, aminophosphonates, polyfunctionally substituted aromatic chelating agents and mixtures thereof. Without pretending to be limited by theory, it was believed that the benefit of these materials is due in part to their exceptional ability to separate the iron and manganese ions from the washing solutions by the formation of soluble chelates. These agents may also be useful in stabilizing leaching components of the present compositions. The aminocarboxylates useful as optional chelating agents include the ethylenediamine tetracetates, N-hydroxyethylene diamine triacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethyltetramine hexacetates, diethyltriamine pentaacetates, and ethylene glycines, alkali metal, ammonium and substituted ammonium salts thereof, and mixtures thereof. The amino phosphonates are also suitable for use as chelating agents in the present compositions, where at least two levels of total phosphorus are allowed in the detergent compositions. Preferably, these aminophosphonates do not contain alkanyl or alkenyl groups with more than about 6 carbon atoms. Preferred amino phosphonates are diethylenetriamine penta (methylenephosphonate acid), ethylene diamine tetra (methylene phosphonic) acid, and mixtures and salts and complexes thereof. Particularly preferred are the sodium, zinc, magnesium and aluminum salt and complexes thereof and mixtures thereof.

POLYMER THICKENING AGENTS The present compositions preferably contain polymeric thickening agents. Suitable polymeric thickening agents include polymeric polycarboxylates and polyethylene glycols, although others known in the art can also be used. It is believed, although not intended to be limited by theory, that polymer dispersion agents enhance the overall performance of the detergency builder, when used in combination with other detergency builders (including lower molecular weight polycarboxylates) by inhibition. of the growth of the crystals, peptization of release of dirt in the form of particles and anti-decay. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful are the water-soluble salts of polymerized acrylic acid.

Enzymes Enzymes may be included in the present compositions for a wide variety of purposes for washing fabrics, including the removal of protein-based, carbohydrate-based or triglyceride-based stains, for example, and for the avoidance of. transfer of refugee dyes, and for the restoration of fabrics. Enzymes that can be incorporated include proteases, amylases, lipases, cellulases and proxidases, as well as mixtures of two or more thereof. Other types of can also be included. enzymes They can be of any suitable origin, such as plant, animal, bacterial, fungal and yeast origin. However, its choice is governed by several factors, such as optimal values of pH activity and / or activity, thermostability, stability in the presence of active detergents, builders, etc. In this respect, bacterial or fungal enzymes, such as amylases and bacterial proteases, and fungal cellulases are preferred. The present compositions typically contain up to about 5%, preferably from about 0.01% to about 2%, more preferably from about 0.2% to about 1%, of commercial enzyme preparations. Suitable examples of proteases are subtilisins that are obtained from particular strains of B. subtilis and B. licheniforms. Another suitable protease is obtained from a Bacillus strain, which has maximum activity throughout the pH range of 8-12, developed and sold by Novo Industries A / S under the registered factory name ESPERASER. In comparison to this enzyme and analogous enzymes, British Patent Specification No. 1,243,784 to Novo is described. Suitable proteolytic enzymes for removing protein-based stains are commercially available, including those sold under the trade names ALCALASER and SAVINASER by Novo Industries A / S (Denmark and MAXATASER by International BioSynthetics, Inc. (The Netherlands). protease A (see European patent application 130 756, published January 9, 1985) protease B (see European patent application 251 446, published January 7, 1988.) Protease enzymes in commercial preparations are they include in the present compositions at levels sufficient to provide from about 0.004 to about 2 Anson units (AU) of activity per gram of the compositions, preferably from about 0.006 to about 0.1 AU, also from about 0.005 to about 0.02 AU. , for example the O-amylases described in the British patent specification No. 1,296,839 (Novo), R APIDASER, International Bio-Synthetics, Inc. and TERMAMYLR, Novo Industries. Amylase is preferably included in the present compositions, such that the activity of the amylase is from about 0.02 KNU to about 5 KNU per gram of the composition, more preferably from about 0.1 KNU to about 2 KNU, more preferably still from about 0.3 KNU to approximately 1 KNU. (KNU is a unit of activity used commercially by Novo Ind). The cellulases usable in the present compositions include both bacterial and fungal cellulase. Preferably, they will have an optimum pH value of 5 and 9.5. Suitable cellulases are disclosed in the US patent. No. 4,435,307, Barbesgoard et al., Issued March 6, 1984, which discloses the fungal cellulase produced by Humicola insolens and the strain Humicola DSM1800, smoke that produces cellulase 212 and belongs to the Aeromonas gene, cellulase extracted from the hepatopancreas of a marine mollusk (Dolabella Auricular Solander). Suitable cells and British patent specifications Nos. 2,075,028 and 2,095,275 and German patent specification No. 2,2247,832 are also described. The cellulases disclosed in PCT Patent Application No. WO 91/17243, such as CAREZYMER (Novo), are especially useful cellulases. Cellulase is preferably included in the present compositions, such that the activity of the cellulase is from about 0.1 CEVU to about 20 CEVU for example of the composition, more preferably from about a CEVU to about 10 CEVU, more preferably still about 2 CEVU at approximately 5 CEVU. (The cellulase activity (CEVU) is determined from the decrease in viscosity of a common CMC solution as follows: Substrate solution containing 35 g / l CMC (Hercules 7 LFD) of the pH alburator is prepared 0.1 M tris, pH 9.0 The analyte cellulase bag is dissolved in the same pH regulator 10 ml of the substrate solution and 0.5 ml of the enzyme solution are shown and transferred to a viscocimeter (for example , Haake VT 181, NV sensor, 181 rpm), and adjusted with a thermostat at 40 ° C. Viscosity readings are taken as soon as possible after mixing and again 30 minutes later The activity of a cellulase solution reduces the viscosity of the substrate solution or medium under these conditions is defined as 1 CEVU / liter). In addition to the ability to interact with the alkylbenzene sulfonate to provide a cleaning under washing conditions and inferiorly improved, it is also surprisingly discovered that the low levels of AES surfactant can reduce or prevent the deactivation of the cellulase enzymes that can be observed in the formulations LAS-based detergents. Without being bound by any theory, it is believed that LAS can reduce the activity of cellulase enzymes by impeding their protein structure. Surprisingly, it has been observed that a low level of AES surfactant can reduce the deactivation effect of LAS on cellulase enzymes. This allows lower levels of cellulase enzyme to be used, thus reducing the cost of the enzyme and increasing the product value for the consumer. Suitable lipase enzymes for detergent use are produced by microorganisms of the Pseudomonas group, such as a Pseudomonas stutzeri ATCC 19, 154, as described in British Patent 1,372,034. See also the lipases of Japanese Patent Application 53/20487, set forth for public inspection on February 24, 1978. This lipase is obtainable from Amano Pharmaceutical Co.

Smectite-type clays can be described as three-layer, expandable clays; that is, aluminosilicates and magnesium silicates, having an ion exchange capacity of at least about 50 meq / 100 g of clay. Preferably, the clay particles are of such size that they can not be tactilely perspired, so that they can not have a gritty feel on the treated fabric of the garment. Fabric softening clay, if included, may be added to the present compositions of the invention to provide about 0.1% to about 20% by weight of the composition, more preferably from about 0.2% to about 15% , and more preferably still from about 0.3% to 10%. Although any of the smectite-type clays are useful in the compositions of the present invention, certain clays are preferred. For example, Gelwhite GP is an extremely white clay form of the smectite type and is therefore preferred when formulating white detergent compositions. Volclay BC, which is a clay mineral of the smectite type that contains at least 3% iron (expressed as Fe2Ü3) in the crystal lattice and which has a very high ion exchange capacity, is one of the clays more effective and effective for use in the present compositions from the point of view of product performance. On the other hand, certain clays of the smectite type are sufficiently contaminated by other silicate minerals and their ion exchange capacities decrease below the required interballo; such clays are not preferred in the present compositions.

Clay flocculating agent It has been found that the use of a clay flocculating agent in a softening clay-containing composition provides improved softening clay deposition on the laundry which results in better softening performance of the laundry, compared to the compositions containing softening clay only. The polymeric clay flocculating agent is selected to provide improved deposition of the fabric softening clay. Typically, such materials have a molecular weight, greater than about 100,000. Examples of such materials may include long chain polymers and copolymers derived from monomers, such as ethylene oxide, acrylamide, acrylic acid, dimethylaminoethyl methacrylate, vinyl alcohol, vinyl pyrrolidone and ethylene imine. Gums are also suitable, such as guar gums. The preferred clay flocculating agent is a polyethylene oxide polymer. The amount of clay flocculating agent included in the present compositions, if any, may be about 0.2% -2%, preferably about 0.5% -l%.

Tissue Transfer Inhibiting Ingredient Another preferred optional component in the present compositions is a dye transfer inhibiting (DTI) ingredient to avoid lowered fidelity and color intensity in fabrics. A preferred DTI ingredient may include polymeric DTI materials capable of binding fugitive dyes to prevent them from depositing on fabrics and DTI decolorization materials capable of discoloring runaway dyes by oxidation. An example of decolorization DTI is hydrogen peroxide or a source of hydrogen peroxide, such as percarbonate or perborate. Non-limiting examples of polymeric DTI materials include poly-vinyl pyrridine N-oxide, poly-vinyl pyrrolidone (PVP), PVP-polybillimidazole copolymer and mixtures thereof. The N-vinylpyrrolidone and the N-vinylimidazole polymers (referred to as "PVP") are also preferred. The amount of DTI included in the present compositions, if any, is about 0.05% -5%, preferably about 0.2% -2%.

Photo Bleaching A preferred optional component of the composition of the present invention is a photo bleaching material, particularly photo phthalocyanine bleaching agents which are described in the U.S. Pat. 4,033,718, issued July 5, 1977, incorporated herein by reference. Preferred bleaching photos are metal-phthalocyanine compounds, the metal preferably having a valence of +2 or +3; Zinc and aluminum are the preferred metals. Such photo whiteners are obtainable, for example, under the name TINOLUS. The zinc-phthalocyanine sulfonate is commercially available under the trade name QUANTUM from Ciba Geigy. Bleach photo components, if included, are typically present in the compositions at levels of up to about 0.02%, preferably from about 0.001% to about 0.015%, more preferably from about 0.002% to about 0.01%.

Fillers Sodium sulfate and sodium carbonate (also known as Calcarab) are well known and are often used as filler components of the present compositions. The fillers also include minerals, such as talc and minerals containing hydrous magnesium silicate, wherein the silicate is mixed with other minerals, for example rocks of ancient origin, such as dolomite. Such sodium sulfate is a preferred filler material. Filler materials, if included, are typically found at levels up to about 60%, preferably from about 25% to about 50%.

METHODS Tolerance test of hardness All glassware used is cleaned and dried perfectly. The sample concentrations used are based on the anhydrous form of the target surfactant for which the hardness tolerance is being examined. The objective surfactant may be a single anionic surfactant or a mixture of anionic surfactants (such as alkylbenzenesulfonate and alkyl sulfate). If the formulation contains anionic, cationic or other anionic surfactants, these are added in additional candies. The experiment is carried out at 22 ± 1 ° C. A surfactant solution of 20 g containing 4,500 ppm of sodium salt of the target surfactant is prepared for which the hardness tolerance of 5,500 ppm of sodium tripolyphosphate, 3,250 ppm of sodium carbonate, 5,295 ppm of sodium sulfate should be measured. sodium and additional amounts of another anionic, cationic or other surfactant, dissolving each component in deionized water at the indicated concentrations. The surfactant solution of 20 g is added to 180 g of a test water having a water hardness specified in units of grains per 3.78 1, using a molar ratio of 3: 1 of Ca ++: Mg ++ ions. The resulting 200 g test solution is stirred vigorously for 30 seconds and then allowed to stand for 40 minutes. If any cationic surfactant is present, the solution is first passed through a cation exchange column to remove any cationic surfactant from the solution. A 10 ml aliquot of the resulting test solution is filtered through a 0.1 mM Gelman Acrodisk syringe filter (VWR Scientific, cat # 28143-309). The first 1 ml of filtrate is discarded and the remaining 8 ml of the filtrate is collected for analysis. The concentration of surfactant (in ppm) in the collected filtrate, Csurf, is then measured quantitatively by a suitable analytical technique, for example, a two-phase titration such as the international standard method ISO 2271 described in the introduction of Surfactant Analysis; Cullum, D.C., Ed .; Blackíe Academic and Professional, Glasgow, 1994; pp 59-64. The concentration of Csurf surfactant will account for the presipitate of any anionic surfactant (including, for example, alkylbenzenesulfonates, alkyl sulfates, alkyl ethoxy ether sulphates, etc.) present in the solution. Preferably, this method is used only when the relative amounts of the other anionic surfactants is small relative to the target surfactants. The result of the hardness tolerance in this test is expressed as the loss in% of the surfactant that is being tested according to the following formula:% loss = ([450 ppm-C3urf (ppm)] +450 ppm) x 100% EXAMPLES EXAMPLE A Using the hardness tolerance method described above, the alkyl ethoxy ether sulfate (AES) was added to a surfactant mass or LAS of anionic surfactant target and an additional cationic surfactant HAQA.

LAS is the objective anionic surfactant, linear C ^ -C ^ alkyl benzene sulphonate, sodium salt. AES is an anionic surfactant, linear Ci2_ci5 ethoxy (3) sulfate, sodium salt. ADHQ is a cationic surfactant, dimethyl-hydroxyethyl-quaternary ammonium chloride of linear C ^ -C ^. "nm" is "not measured". The results show that the addition of AES reduces the amount of LAS surfactant precipitated by the hardness of water in the test water solution and thus lost by the cleaning performance. Since it is an anionic surfactant, the collected precipitate may include precipitated AES. However, it is known that the AES is affected less than the LAS by the water hardness and the amount of AES is low in relation to the amount of LAS (less than 10% of the LAS level).
