Title (EN) LIQUID DETERGENTS
(FR) DETERGENTS LIQUIDES
Abstract:
(EN) 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.
(FR) Composition détergente comprenant une dispersion de gouttelettes lamellaires de matériaux à activité détergente en phase continue aqueuse. Ladite composition comprend de 0,1 à 16 % en poids de matériaux tensio-actifs, moins de 20 % en poids de STP avec du matériau adjuvant à zéolithe, ou n'en comprend pas du tout, ainsi qu'un polymère défloculant; à condition que (a) lorsque les matériaux tensio-actifs représentent entre 12 % et 16 % en poids de la composition, la composition comprend moins de 7 % en poids de STP avec du matériau adjuvant à zéolithe, ou n'en comprend pas du tout; et que (b) lorsque la composition comprend entre 3 % et 12 % en poids d'un sulfoné benzénique d'alkyle de potassium, entre 2 % et 8 % en poids d'un savon d'acide gras de potassium, entre 0,5 % et 5 % en poids d'un tensio-actif non ionique, et entre 1 % et 25 % en poids de STP et/ou de pyrophosphate de tétrapotassium, le rapport de poids entre ledit sulfoné et ledit tensio-actif non ionique étant compris entre 3:5 et 25:1, et la quantité totale de sulfoné, de savon et de tensio-actif non ionique étant comprise entre 7,5 et 20 % en poids, alors le polymère défloculant n'est pas uniquement constitué d'entre 0,1 et 2 % en poids d'un copolymère neutralisé et partiellement estérifié d'anhydride maléique avec de l'éther vinylméthylique, de l'éthylène ou du styrène.
