Abstract:
A liquid lamellar cleansing composition comprising:(a) 5% to 50% by wt. of a surfactant system comprising:(i) one or more anionic surfactants where the one anionic or one of the at least two anionics is a sodium tricedeth sulfate;(ii) 0.1 to 25% by wt. total composition of an additional surfactant selected from the group consisting of amphoteric, zwitterionic or mixtures thereof; and(b) 1 % to 15% by wt. fatty acid or ester thereof;wherein composition has initial viscosity of 20,000 to 300,000 cps. measured at 0.5 RPM using T-bar spindle A; and freeze-thaw viscosity defined either by having viscosity greater than about 30,000 cps also measured at 0.5 RPM using T-bar spindle A; or by having a percent drop of viscosity relative to initial viscosity of no more than about 40%.
