Patent

CA 2226577

There is provided a detergent composition suitable for use in laundry and dishwashing methods comprising: (a) a foaming surfactant system comprising surfactant selected from anionic, non-ester cationic, nonionic, ampholytic, amphoteric and zwitterionic surfactants and any mixtures thereof; (b) a hydrolysable cationic ester surfactant; (c) an alkalinity system having the capacity to deliver alkalinity to a wash solution as measured by the alkalinity release test method described herein such that the % weight NaOH equivalent of the composition is greater than 5 % by weight of the composition; and (d) an antifoam compound wherein the weight ratio of foaming surfactant to cationic ester surfactant is from 100:1 to 2:1 and the weight ratio of cationic ester surfactant to antifoam compound is from 50:1 to 1:5.

L'invention concerne une composition détergente convenant au lavage du linge ou de la vaisselle comprenant (a) un système tensioactif moussant comprenant un tensioactif choisi parmi les tensioactifs anioniques, cationiques autres que du type ester, non ioniques, ampholytes, amphotères et zwitterioniques ou leurs mélange; (b) un tensioactif cationique du type ester, hydrolysable; (c) système alcalin capable de conférer à une solution de lavage une alcalinité, mesurée par l'essai de libération décrit ici et exprimée en équivalent de NaOH, supérieure à 5 % en poids de la composition; et (d) un agent antimousse. Dans cette composition, le rapport pondéral du tensioactif moussant sur le tensioactif cationique du type ester est de 100:1 à 2:1 et le rapport pondéral du tensioactif cationique du type ester sur l'agent antimousse est d'environ 50:1 à 1:5.
