Definitions

  • This invention relates to detergent compositions for washing fabrics, in particular to detergent compositions which are capable of cleaning and softening fabrics from the same wash liquor.
  • compositions for simultaneously cleaning and softening fabrics are known in the art.
  • Conventionally such compositions contain, as a detergent active material, an anionic surfactant to clean the fabrics and a cationic fabric softening agent.
  • anionic and cationic components of such compositions to react with each other, either in the product itself or in the wash liquor, with the result that the efficiency of the cationic softening agent is significantly reduced.
  • An alternative proposal is to avoid the use of anionic surfactants, by for example using nonionic surfactants as described in British Patent Specification GB 1 079 388 (GENERAL FOODS CORPORATION).
  • a further series of proposals relate to the use of alternative fabric softening agents in place of the cationic material.
  • One such example is to use cellulolytic enzymes,ie cellulase, as a harshness-reducing agent, as disclosed in British Patent Specification GB 1 368 599 (UNILEVER).
  • Other enzymes such as proteolytic enzymes like Alcalase, do not provide softening benefits.
  • a further example is to use various clay materials as disclosed in United States patent specification US 4 062 647 (STORM et al assigned to THE PROCTER & GAMBLE COMPANY).
  • cellulase achieves its anti-harshening effect on eg cotton, by cleaving and thereby assisting the removal of the cellulosic fibrils which form on the fabric fibres in the normal washing process, the bonding of these fibrils to each other and the cotton fibres themselves being responsible for introducing a degree of rigidity, that is harshening, to the fabric surface.
  • clay materials achieve their softening benefit by coating the fibres and fibrils with a layer of lubricating material thereby lowering the friction between fibrils and fibrils/fibres reducing the tendency of the fibrils to bond together.
  • compositions contains cellulase as a fabric softening agent, there is nothing to be gained from the additional inclusion of clay materials, the fibrils having been removed following cellulase action.
  • a composition contains a clay material as a softening agent, there is nothing to be gained from the additional inclusion of cellulase, the clay coating in the fibrils effectively screening the fibrils from attack by the cellulase, which is known to be selective towards cellulosic materials and not in any way to attack clay materials.
  • compositions which contain both cellulase and clay materials these softening agents would appear to mutually inhibit one another and we believe it is for this reason that compositions containing both cellulase and clay materials as softening agents have not previously been proposed.
  • a detergent composition for cleaning and softening fabrics comprising:
  • compositions according to the invention necessarily contain a detergent active material, otherwise referred to herein simply as a detergent compound.
  • the detergent compounds may be selected from anionic, nonionic, zwitterionic and amphoteric synthetic detergent active materials. Many suitable detergent compounds are commercially available and are fully described in the literature, for example in "Surface Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch.
  • the preferred detergent compounds which can be used are synthetic anionic and nonionic compounds.
  • the former are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C8-C18 ) alcohols produced for example from tallow or coconut oil, sodium and potassium alkyl (C9-C20) benzene sulphonates, particularly sodium linear secondary alkyl (C10-C15) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C8-C18) fatty alcohol-alkylene oxide, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acid amides of methyl taurine; alkane mono
  • Suitable nonionic detergent compounds which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
  • Specific nonionic detergent compounds are alkyl (C6-C22) phenols-ethylene oxide condensates, generally 5 to 25 EO, ie 5 to 25 units of ethylene oxide per molecule, the condensation products of aliphatic (C8-C18) primary or secondary linear or branched alcohols with ethylene oxide, generally 5 to 40 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine.
  • Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxides and dialkyl sulphoxides.
  • detergent compounds for example mixed anionic or mixed anionic and nonionic compounds may be used in the detergent compositions, particularly in the latter case to provide controlled low sudsing properties. This is beneficial for compositions intended for use in suds-intolerant automatic washing machines.
  • Amounts of amphoteric or zwitterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due to their relatively high cost. If any amphoteric or zwitterionic detergent compounds are used it is generally in small amounts in compositions based on the much more commonly used synthetic anionic and/or nonionic detergent compounds.
  • the effective amount of the detergent active compound or compounds used in the composition of the present invention is generally in the range of from 2 to 50%, preferably from 5 to 40% by weight, most preferably not more than 30% by weight of the composition.
  • a second essential component of the compositions of the present invention is a fabric softening clay material.
  • This clay material should be a phyllosilicate clay with a 2:1 layer structure, which definition includes pyrophyllite clays, smectite or montmorillonite clays, saponites, vermiculites and micas.
  • Clay materials which have been found to be unsuitable for fabric softening purposes include chlorites and kaolinites.
  • Other aluminosilicate materials which do not have a layer structure, such as zeolites are also unsuitable as fabric softening clay materials.
  • Particularly suitable clay materials are the smectite clays described in detail in US-A-3 959 155 (MONTGOMERY et al assigned to THE PROCTER & GAMBLE COMPANY), especially smectite clays such as described in US-A-3 936 537 (BASKERVILLE - referred to above)
  • Other disclosures of suitable clay materials for fabric softening purposes include European patent specification EP 26528-A (PROCTER & GAMBLE LIMITED).
  • the most preferred clay fabric softening materials include those materials of bentonitic origin, bentonites being primarily montmorillonite type clays together with various impurities, the level and nature of which depends on the source of the clay material.
  • the level of fabric softening clay material in the compositions of the invention should be sufficient to provide the fabrics with a softening benefit.
  • a preferred level is 1.5% to 35% by weight of the composition, most preferably from 4% to 15%, these percentages referring to the level of the clay mineral per se .
  • Levels of clay raw material higher than this may be necessary when the raw material is derived from a particularly impure source.
  • a third essential component of the compositions of the invention is the cellulase.
  • the cellulase in the present invention may be any bacterial or fungal cellulase having a pH optimum of between 5 and 11.5. It is however preferred to use cellulases which have optimum activity at alkaline pH values, such as those described in British Patent Specifications GB 2 075 028 A (NOVO INDUSTRIE A/S), GB 2 095 275 A (KAO SOAP CO LTD) and GB 2 094 826 A (KAO SOAP CO LTD).
  • alkaline cellulases examples include cellulases produced by a strain of Humicola insolens (Humicola grisea var. thermoidea), particularly the Humicola strain DSM 1800, and cellulases produced by a fungus of Bacillus N or a cellulase 212-producing fungus belonging to the genus Aeromonas, and cellulase extracted from the hepatopancreas of a marine mullosc (Dolabella Auricula Solander).
  • the cellulase added to the composition of the invention may be in the form of a non-dusting granulate, eg "marumes” or “prills", or in the form of a liquid in which the cellulase is provided as a cellulase concentrate suspended in eg a nonionic surfactant or dissolved in an aqueous medium, having cellulase activity of at least 250 regular C x cellulase activity units/gram, measured under the standard conditions as described in GB 2 075 028 A.
  • the amount of cellulase in the composition of the invention will, in general, be from about 0.1 to 10% by weight in whatever form.
  • the use of cellulase in an amount corresponding to from 0.25 to 150 or higher regular C x units/gram of the detergent composition is within the preferred scope of the present invention.
  • a most preferred range of cellulase activity is from 0.5 to 25 regular C x units/gram of the detergent composition.
  • compositions of the invention will generally include a detergency builder to improve the efficiency of the detergent active, in particular to remove calcium hardness ions from the water and to provide alkalinity.
  • the builder material may be selected from precipitating builder materials (such as alkali metal carbonates, bicarbonates, borates, orthophosphates and silicates), sequestering builder materials (such as alkali metal pyrophosphates, polyphosphates, amino polyacetates, phytates, polyphosphonates, aminopolymethylene phosphonates and polycarboxylates), ion-exchange builder materials (such as zeolites and amorphous aluminosilicates), or mixtures of any one or more of these materials.
  • precipitating builder materials such as alkali metal carbonates, bicarbonates, borates, orthophosphates and silicates
  • sequestering builder materials such as alkali metal pyrophosphates, polyphosphates, amino polyacetates,
  • builder materials include sodium tripolyphosphate, mixtures thereof with sodium orthophosphate, sodium carbonate, mixtures thereof with calcite as a seed crystal, sodium citrate, zeolite and the sodium salt of nitrilotriacetic acid.
  • the level of builder material in the compositions of the invention may be up to 80% by weight, preferably from 20% to 70% by weight and most preferably from 30% to 60% by weight.
  • a detergent composition of the invention can contain any of the conventional additives in the amounts in which such additives are normally employed in fabric washing detergent compositions.
  • these additives include the lather boosters such as alkanolamides, particularly the monoethanolamides derived from palm kernel fatty acids and coconut fatty acids, lather depressants, oxygen-releasing bleaching agents such as sodium perborate and sodium percarbonate, peracid bleach precursors, chlorine-releasing bleaching agents such as tricloroisocyanuric acid, inorganic salts such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes, other enzymes such as proteases and amylases, germicides and colourants.

  • compositions of the invention an antistatic agent, to reduce the level of static on washed fabrics, especially those fabrics which include synthetic fibres, such as nylon.
  • the antistatic agents useful herein are quaternary ammonium salts of the formula [R1R2R3R4N] + Y - wherein at least one, but not more than two, of R1, R2, R3 and R4 is an organic radical containing a group selected from a C16-C22 aliphatic radical, or an alkyl phenyl or alkyl benzyl radical having 10-16 atoms in the alkyl chain, the remaining group or groups being selected from hydrocarbyl groups containing from 1 to about 4 carbon atoms, or C2-C4 hydroxy alkyl groups and cyclic structures in which the nitrogen atom forms part of the ring, and Y is an anion such as halide, methylsulfate, or ethylsulfate.
  • the hydrophobic moiety ie, the C16-C22 aliphatic, C10-C16 alkyl phenyl or alkyl benzyl radical

  • the quaternaries are often made from alkyl halide mixtures corresponding to the mixed alkyl chain lengths in fatty acids.
  • the "ditallow" quaternaries are made from alkyl halides having mixed C14-C18 chain lengths. Such mixed di-long chain quaternaries are useful herein and are preferred from a cost standpoint.
  • the tallow alkyl groups are hydrogenated or "hardened” to reduce the level of unsaturation and thereby raise the melting point and lower the water-solubility of compounds made therefrom.
  • disallow is intended to refer to the above-described ditallowalkyl quaternaries, either in their hardened or unhardened forms.
  • the quaternary ammonium antistatic compounds useful herein include both water-soluble and substantially water-insoluble materials.
  • Imidazolinium compounds enumerated in US 3 936 537 possess appreciable water solubility and are preferably utilised in the present invention by mixing with an appropriate type and level of organic dispersion inhibitor and complexing component to give ultimate particle solubility in water of less than 50 ppm (parts per million) at 25°C.
  • Relatively water-soluble quaternary ammonium antistatic agents may also be of the nonring variety, such as diisostearyl dimethyl ammonium chlorides.
  • Exemplary quaternary ammonium imidazolinium compounds are specifically methyl-1-alkylamidoethyl-2-alkyl imidazolinium methyl sulfates, specifically 1-methyl-1-[(tallowamido)ethyl]-2-tallowimidazolinium methyl sulfate.
  • the most useful quaternary ammonium antistatic agents are characterised by relatively limited solubility in water.
  • Dioctadecyldimethyl ammonium chloride is an especially preferred quaternary antistatic agent for use herein by virtue of its high antistatic activity; ditallow dimethyl ammonium chloride is equally preferred because of its ready availability and its good antistatic activity; other useful di-long chain quaternary compounds are dicetyl dimethyl ammonium chloride; bis-docosyl dimethyl ammonium chloride; didodecyl dimethyl ammonium chloride; ditallow dimethyl ammonium bromide; dioleyoyl dimethyl ammonium hydroxide; ditallow dimethyl ammonium chloride; ditallow dipropyl ammonium bromide; ditallow dibutyl ammonium fluoride; cetyldecylmethylethyl ammonium chloride; bis-[ditallow dimethyl- ammonium] sulfate; and

  • the compositions of the invention need not contain more than 10% by weight, generally not more than 6% by weight antistatic agent.
  • compositions of the invention may also include organic amines.
  • Suitable amines include primary, secondary and tertiary amines, such as hydrogenated tallow alkyl primary amine, secondary coconut methyl amine or methyl di-hardened tallow alkyl tertiary amine. The presence of such amines in the composition is known to enhance the perfume delivery to the fabrics.
  • a suitable level for the amine in the composition is from 1.0% to 10%, most preferably 1.5% to 6% by weight.
  • the detergent compositions may be prepared in any way appropriate to their physical form such as by dry-mixing the components, co-agglomerating them or dispersing them in a liquid carrier.

  • the spray-drying tower inlet temperatures are normally in the range of 300°-360°C and the resultant spray-dried granules have a moisture content of 8-12% by weight.
  • An optional, but preferred, additional processing step is to cool the dried granules rapidly by means of cool air from a temperature of 90°C to a temperature in the range of 25°-35°C, in order to facilitate the further processing of the product.
  • Solid heat-sensitive components such as persalts and enzymes, are mixed with the spray-dried granules.
