Definitions
- the present invention relates to granular detergent compositions containing a specific mixture of alkylbenzene sulfonate surfactant, alkyl sulfate surfactant, alkali metal silicate and sodium sulfate.
- the compositions are prepared by drying, preferably by spray-drying, an aqueous slurry comprising the above components.
- composition in accordance with the invention preferably also contains detergent builder materials, it should be substantially free of pyrophosphate and anhydrous Form 1 tripolyphosphate builder in that portion of the composition prepared by drying the slurry comprising the sulfonate and sulfate surfactants, silicate and sulfate.
- alkylbenzene sulfonate and alkyl sulfate surfactants are desired for optimum detergency performance.
- such mixtures tend to gel on contact with water. This can result in poor solubility of granules having high levels of alkylbenzene sulfonate and alkyl sulfate surfactants, particularly when such granules are incorporated in dense detergent compositions.
- soluble granular detergent compositions containing high levels of alkylbenzene sulfonate and alkyl sulfate surfactants can be obtained by drying an aqueous slurry comprising the surfactants, silicate in a weight ratio of surfactant to silicate within the range of from 1.5:1 to 6:1, sodium sulfate and substantially no pyrophosphate or anhydrous Form I tripolyphosphate detergent builder material.
- these soluble detergent granules are admixed or agglomerated with builders, and other optional detergent ingredients.
- compositions are obtained by admixing the soluble granules with builders, compacting the admix at relatively low pressures (e.g., 137.9 kPa to 1379 kPa and optionally admixing additional builders and other ingredients to provide finished granular detergent compositions.
- relatively low pressures e.g., 137.9 kPa to 1379 kPa
- additional builders and other ingredients e.g., 137.9 kPa to 1379 kPa
- Such a process is the subject of the commonly assigned European Patent Application Publication No 0220024.
- the compositions can also contain 0-20% of other surfactants such as alkylbenzene sulfonates.
- Spray-dried detergents containing mixtures of alkylbenzene sulfonate and alkyl ethoxy sulfate surfactants, silicate and builders are exemplified.
- the particles are mixed with spray-dried base granule containing about 27% of a mixture of alkylbenzene sulfonate and alkyl ethoxy sulfate surfactants, 18% silicate and about 22% sodium tripolyphosphate.
- EP-A-0084657 discloses physically stable strongly foaming spray-dried granular detergent compositions comprising 35-50% C 10 -C 14 4 alkylbenzene sulfonates, 0-15% C 10 -C 20 alkyl sulfates, 5-20% sodium silicate, 0-10% sodium sulfate, 5-25% sodium tripolyphosphate and 5-25% sodium aluminosilicate zeolite.
- AU-A-61106 discloses mixtures of linear C 10 -C 1 5 alkyl benzene sulfonates and C 14 -C 1 a alkyl sulfates in a tripolyphosphate-built, silicate- and sulfate-containing spray-dried detergent composition having enhanced cleaning properties.
- Japanese, OPI 106509, published August 21, 1979 discloses spray-dried granular detergents containing 15-40% surfactant, 5-20% silicate and no more than 12% phosphate.
- the compositions are said to have good physical properties and to cause less deposition of insolubles on clothes.
- Japanese OPI 72998 and 72999 published April 25, 1985, discloses dense granular detergents formed by high shear mixing of alkylbenzene sulfuric acid and alkyl sulfuric acid with sodium carbonate and water to cause neutralization, admixing other ingredients such as builders, and then crushing and granulating the mixture.
- a granular detergent composition prepared by drying an aqueous slurry, said composition comprising, by weight:
- the granular detergent compositions of the present invention contain from 30% to 60%, preferably from 35% to 60%, more preferably from 40% to 50%, by weight of a mixture of C 11 -C 1 3 alkylbenzene sulfonate surfactant and C 12 -C 1 6 alkyl sulfate surfactant in a weight ratio of sulfonate surfactant to sulfate surfactant of from 4:1 to 1:4, preferably from 3:1 to 1:3, more preferably from 2:1 to 1:2.
- Sulfonate surfactants useful herein are the water-soluble salts, particularly the alkali metal, ammonium and alkanolammonium (e.g., monoethanolammonium or triethanolammonium) salts of alkylbenzene sulfonates in which the alkyl group contains from 11 to 13 carbon atoms, in straight chain or branched chain configuration e.g., those of the type described in U.S. Patents 2,220,099 and 2,477,383.
- alkali metal, ammonium and alkanolammonium e.g., monoethanolammonium or triethanolammonium
- Useful alkyl sulfate surfactants are the water-soluble salts, particularly the alkali metal, ammonium and alkanolammonium (e.g., monoethanolammonium or triethanolammonium) salts of C 12 -C 1 6 linear or branched alkyl sulfates. Preferred are those containing a C 12 -C 15 , especially C14-C15, linear alkyl group.
- compositions herein can also contain minor amounts (generally less than about 30%, but preferably less than about 15%, by weight of the above sulfonate and sulfate surfactants) of other detergent surfactants known in the art.
- minor amounts can include anionic, nonionic, cationic, ampholytic and zwitterionic surfactants, such as those disclosed in U.S. Patent 3,919,678, Laughlin, et al, issued December 30, 1975.
- compositions of the present invention also contain an alkali metal silicate having a molar ratio of Si0 2 to alkali metal oxide of from 1.0 to 3.2, preferably from 1.6 to 2.4.
- the alkali metal silicates can be purchased in either liquid or granular form. Silicate solutions or slurries can conveniently be used to avoid having to dissolve the dried form in the aqueous slurry (e.g., crutcher mix) of the components herein.
- aqueous slurry e.g., crutcher mix
- the weight ratio of the alkylbenzene sulfonate plus alkyl sulfate surfactants herein to the alkali metal silicate must be from 1.5:1 to 6:1, preferably from 2:1 to 4:1, more preferably from 2.5:1 to 3.5:1.
- compositions further contain from 10% to 60%, preferably from 20% to 50%, by weight of sodium sulfate.
- Sodium sulfate is usually formed during the sulfation/sulfonation and neutralization steps in the production of the alkylbenzene sulfonate and alkyl sulfate surfactants herein.
- compositions herein are prepared by drying an aqueous slurry comprising the components.
- the slurry generally contains from 25% to 70%, preferably from 40% to 60%, water, whereas the dried granules initially contain from 1% to 10%, preferably from 1% to 3%, water.
- the drying operation can be accomplished by any convenient means, such as by using spray-drying towers, both counter-current and co-current, fluid beds, flash-drying equipment, or industrial microwave or oven-drying equipment. Those are more fully described in U.S. Patent 4,019,998, Benson et al, issued April 26, 1977 (particularly from Column 14, line 19 to Column 15, line 9).
- the granular detergents herein are very soluble in the wash water even though they contain high levels of alkylbenzene sulfonate and alkyl sulfate surfactants. Good solubility is obtained when the weight ratio of total sulfonate plus sulfate surfactant to silicate is within the 1.5:1 to 6:1 range specified above. While not intending to be limited by theory, it is believed that this relatively high level of silicate provides structure and helps to maintain integrity of the high surfactant granules and that this minimizes gelling when the surfactants contact the wash water.
- the silicate level becomes too high (e.g., a surfactant to silicate ratio of 1:1), overall solubility can suffer due to the formation of silicate insolubles.
- granules having a surfactant to silicate ratio of, for example, 8:1 have insufficient structure and tend to be too mushy at these high surfactant levels.
- the portion of the granular detergent obtained by drying an aqueous slurry of the essential components of the composition of the present invention should be free or substantially free of detergent pyrophosphate or anhydrous Form 1 tripolyphosphate builder.
- substantially free means less than 5%, preferably less than 3%, by weight of such builder material.
- the composition can contain up to 60% preferably from 1 % to 45% by weight of non-phosphate detergent builders including any of those described in US Patent 3,925,262, Laughlin et al, issued December 9, 1975.
- Builders are generally selected from the various water-soluble alkali metal, ammonium or substituted ammonium phosphonates, polyphosphonates, carbonates, borates, polyhydroxy sulfonates, polyacetates, carboxylates, and polycarboxylates.
- polyphosphonate builders are the sodium and potassium salts of ethylene diphosphonic acid, the sodium and potassium salts of ethane 1-hydroxy-1, 1-diphosphonic acid and the sodium and potassium salts of ethane, 1,1,2-triphosphonic acid.
- Other phosphorus builder compounts are disclosed in US Patents 3,159,581; 3,213,030; 3,422,021; 3,422,1137; 3,400,176; and 3,400,148.
- nonphosphorus, inorganic builders are sodium and potassium carbonate, bicarbonate, sesquicarbonate, and tetraborate decahydrate.
- Water-soluble, nonphosphorus organic builders useful herein include the various alkali metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates and polyhydroxy sulfonates.
- polyacetate and polycarboxylate builders are the sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylene diamine tetraacetic acid, nitrilotriacetic acid, oxydisuccinic acid, mellitic acid, benzene polycarboxylic acids, and citric acid.
- Polymeric polycarboxylate builders are also described in U.S Patent 3,308,067, Diehl, issued March 7, 1967. Such materials include the water-soluble salts of homo- and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid and methylenemalonic acid.
- Other useful builders herein are sodium and potassium carboxymethyloxymalonate, carboxymethylox- ysuccinate, cis-cyclohexanehexacarboxylate, cis-cyclopentanetetracarboxylate, phloroglucinol trisulfonate, and the copolymers of maleic anhydride with vinyl methyl ether or ethylene.
- polycarboxylates are the polyacetal carboxylates described in U.S. Patent 4,144,226, issued March 13, 1979 to Crutchfield et al, and U.S. Patent 4,246,495, issued March 27, 1979 to Crutchfield et al.
- polyacetal carboxylates can be prepared by bringing together under polymerization conditions an ester of glyoxylic acid and a polymerization initiator. The resulting polyacetal carboxylate ester is then attached to chemically stable end groups to stabilize the polyacetal carboxylate against rapid depolymerization in alkaline solution and converted to the corresponding salt.
- a preferred builder for use in compositions that are substantially free of phosphorus-containing builders is sodium citrate.
- the above granular detergent compositions can be used as finished detergent compositions or as detergent additive compositions. However, they are preferably used as (and hereinafter referred to as) detergent base granules which are then admixed or agglomerated with builder material and with other optional ingredients to provide finished detergent compositions exhibiting good solubility.
- Such finished compositions can comprise by weight from 5% to 50%, preferably from 10% to 40%, more preferably from 12% to 25%, of the alkylbenzene sulfonate and alkyl sulfate surfactants herein and from 5% to 95%, preferably from 10% to 85%, more preferably from 15% to 75%, of detergent builder material.
- the builders herein should have the same particle size as the remainder of the composition, as described hereinafter.
- the detergent builder materials that are admixed can include any of those described above and may also include phosphate materials such as sodium and potassium tripolyphosphate, polymeric metaphosphate having a degree of polymerisation of from 6 to 21 and orthophosphate.
- the tripolyphosphate is preferably present as Form II or hydrated Form I and for best solubility, the amount of pyrophosphate and anhydrous Form I tripolyphosphate should be minimised, i.e. the finished compositions preferably contain from 0% to 20%, preferably from 0% to 10%, of such material or mixtures thereof.
- compositions can also contain minor amounts, generally less than 30%, preferably less than 20%, by weight of other ingredients usually included in detergent compositions.
