Abstract
The present invention relates to lamellar phase compositions comprising defined surfactant systems and a structurant selected from the group consisting of liquid fatty acids liquid alcohols and derivatives thereof which structurant is responsible for inducing the lamellar phrase. The invention also relates to a method of inducing said lamellar phase in such compositions by adding the defined structurant.
Claims5
A method for inducing a lamellar phase in a liquid cleansing composition comprising:
- (a) 5% to 50% by wt. of a surfactant system comprising:
- (i) an anionic surfactant selected from the group consisting of acyl isethionates, alkyl sulfates, alkyl carboxylates, alkyl sulfosuccinates, alkyl phosphates and mixtures thereof;
- and
- (ii) an amphoteric and/or zwitterionic surfactant selected from the group consisting of amphoacetates, betaines and mixtures thereof;
- and
- (b) 1 to 20% by wt. emollient, even where said emollient and a structurant defined in (b)(i) and (b)(ii) below are the same;
- which method comprises adding about 0.1 to 15% by wt. of a structurant selected from the group consisting of:
- (i) C.sub.8 to C.sub.24 unsaturated and/or branched liquid fatty acid selected from the group consisting of oleic acid and isostearic acid;
- or an ester derivative of said fatty acid selected from the group consisting of propylene glycol isostearate, propylene glycol oleate, glyceryl isostearate, glyceryl oleate, and polyglyceryl diisostearate;
- and
- (ii) oleyl alcohol or ether thereof;
- wherein said structurant has a melting point below about 25.degree. C.
