Abstract: Disclosed is a method for preparing a stabilized enzyme dispersion wherein the dispersion is prepared by precipitating a water-soluble polymer from a single phase, aqueous solution to form an aqueous dispersion, and before, simultaneously with or after precipitating the polymer, contacting the dissolved or dispersed polymer with an aqueous solution or fine aqueous dispersion of an enzyme without any covalent bonding between the polymer and the enzyme. Also disclosed is a clear solution for use in the method.

Abstract: Pourable, fluid, non sedimenting, laundry detergent composition, comprising water, surfactant, builder, a surfactant desolubilizing electrolyte and, optionally, the usual minor ingredients, consist essentially of: at least one predominantly aqueous liguid phase which is separable into a distinct layer by centrifuging the composition at 800 times normal earth gravity at 25.degree. C. for 17 hours, and which contains at least part of the electrolyte and less than 75% by weight, preferalby less than 10% by weight, of the surfactant, and one or more other phases which together contain at least part of the builder as solid particles dispersed in the composition and at least part of the surfactant, preferably either as a network of solid surfactant hydrate, or as a "G" phase liquid crystal which may be associated with an "L" phase, micellar solution.

Abstract: Liquid detergent compositions suitable for laundry use consist essentially of water, Electrolyte, Active Ingredient and preferably a Builder. They comprise a space-filling, floc-like aggregate of surfactant containing spherulites, substantially cocontinuous with an aqueous liquid micellar solution. They are shear thinning, mobile, stable to shear stress, storage under extreme climatic conditions and high pH.

Abstract: Surfactant mixtures are prepared in a fluid "G" phase of more than 50% concentration, the mixtures comprise different surfactant products selected respectively from at least two of the following classes, that is to say alkyl sulphates, alkyl ether sulphates, olefin sulphonates, alkyl benzene sulphonates, alkyl sulphosuccinates, alkyl ether sulphosuccinates, alkyl sulphosuccinamates, paraffin sulphonates, fatty carboxylates, alkyl ether carboxylates, alkyl phosphates, alkyl ether phosphates, alkyl phenol sulphates, alkyl phenyl ether sulphates, alkyl phenyl ether sulphonates, fatty ester sulphonates, fatty acid sulphonates, acyl sarcosinates and acyl taurides.

Abstract: Aqueous surfactant mixtures comprising a first amphoteric surfactant and at least one non-ionic surfactant and/or at least one amphoteric surfactant non-homologous with the first amphoteric surfactant, are obtained at a concentration substantially higher than previously obtainable by preparing them in the presence of sufficient water to form a "G" phase.

Abstract: Mixtures of amphoteric and anionic surfactants are obtained as concentrated aqueous systems in the G phase.

Abstract: Alkyl sulphates are prepared in a high concentration by mixing together an alkyl sulphuric acid and ammonium or an amine in the presence of sufficient water to maintain the product in the G phase above the minimum concentration at which gel formation is encountered.
