Abstract (en)
[origin: WO9109108A1] A detergent composition comprising a dispersion of lamellar droplets of detergent active materials in an aqueous continuous phase, said composition comprising from 0.1 to 16 % by weight of surface active materials and no or less than 20 % by weight of STP plus zeolite builder material, said composition also comprising a deflocculating polymer; with the provisos that (a) when the level of surface active materials is between 12 % and 16 % by weight of the composition, then the composition comprises no or less than 7 % by weight of STP plus zeolite builder material; and (b) when the composition comprises from 3 % to 12 % of a potassium alkyl benzene sulphonate, from 2 % to 8 % of a potassium fatty acid soap, from 0.5 to 5 % of a nonionic surfactant, and from 1 to 25 % of STP and/or tetrapotassium pyrophosphate, all percentages being by weight, the weight ratio of said sulphonate to said nonionic surfactant being from 3:5 to 25:1, and the total amount of said sulphonate, soap and nonionic surfactant being from 7.5 to 20 % by weight, then the deflocculating polymer does not consist solely of from 0.1 to 2 % by weight of a partially esterified, neutralised copolymer of maleic anhydride with vinylmethyl ether, ethylene or styrene.
