The invention provides liquid cleanser compositions which 15 to 50 wt% of fatty acyl isethionate surfactant product containing 10 to 50 wt% fatty acids and/or fatty soaps and 35 to 85 wt% fatty acyl isethionate in the said product, said product comprising at least 60% of total surfactant product in the liquid composition and comprising; 1% by wt. and above of an elevated temperature stabilizing system comprising: (i) 0.1 to 8 wt% of a compound selected from the group consisting of alkylamidoamide, alkylamineoxide and mixture of above; (ii) 0.3 to 8 wt% of a compound selected from the group consisting of C9 to C30 aliphatic hydrocarbon oils, ammonium salt, organic amine, linear C8 to C13 fatty acid/fatty alcohol, branched fatty acid and mixtures thereof, wherein the total amount of fatty alcohols and branched fatty acids is no more than 2 wt% in the liquid composition. The key is to insure a specific combination of surfactant crystal modifiers so that the fatty acyl isethionate-containing liquid composition will be stable at low and high temperatures. |
