Patent

CA 2226621

There is provided a surfactant system comprising: (a) an anionic sulfate surfactant component; (b) a cationic ester surfactant; and (c) a hydrophilic alkoxylated nonionic surfactant having a HLB value of at least 9.1, wherein the weight ratio of anionic sulfate surfactant component to cationic ester surfactant is from 2.5:1 to 20:1 and the weight ratio of anionic sulfate surfactant component to hydrophilic alkoxylated nonionic surfactant is from 1:5 to 5:1. Alternatively, component (c) is a hydrophilic surfactant system comprising a plurality of nonionic surfactant components.

L'invention se rapporte à un système surfactif comprenant: (a) un constituant tensioactif anionique à base de sulfate; (b) un tensioactif cationique à base d'ester; et (c) un tensioactif hydrophile alcoxylé non ionique dont le rapport hydro-lipophile est au moins égal à 9,1. Le rapport de poids entre le constituant tensioactif anionique à base de sulfate et le tensioactif cationique à base d'ester est compris entre 2,5:1 et 20:1. Le rapport entre le constituant tensioactif anionique à base de sulfate et le tensioactif hydrophile alcoxylé non ionique est compris entre 1:5 et 5:1. A titre de variante, le constituant (c) peut être un système tensioactif hydrophile renfermant une pluralité de constituants tensioactifs non ioniques.
