Abstract
The present invention relates to a method of enhancing low temperature stability of lamellar structured liquid cleansing compositions comprising 5% to 50% of a surfactant system comprising (a) anionic or mixture of anionics and (b) an amphoteric and/or zwifterionic surfactant, wherein said method comprises selecting component (b) such that alkalimetal alkylamphoacetate comprises greater than 25% to 90% of said component (b).
Claims7
A method of enhancing low temperature stability of a lamellar structured liquid cleansing compositions comprising:
- (1) 5% to 50% by wt. of a surfactant system which surfactant system comprises:
- (a) anionic or mixture of anionic surfactants;
- and
- (b) an amphoteric and/or zwitterionic surfactant or mixture thereof;
- and
- (2) 0.1 to 15% by wt. of a structurant selected from the group consisting of:
- (a) unsaturated, unbranched C.sub.8 to C.sub.24 liquid fatty acid or ester thereof;
- (b) saturated, branched C.sub.8 to C.sub.24 liquid fatty acid or ester thereof;
- (c) unsaturated, unbranched C.sub.8 to C.sub.24 liquid alcohol or ether thereof;
- (d) saturated, branched C.sub.8 to C.sub.24, liquid alcohol or ether thereof;
- (e) short chain saturated fatty acid selected from the group consisting of capric acid, caprylic acid and mixtures thereof;
- and
- (f) mixtures thereof;
- wherein said method comprises selecting the amphoteric and/or zwitterionic surfactant component (1)(b) such that alkalimetal alkyl amphoacetate comprises greater than 25% to 90% of said component (b).
