ABSTRACT:
The invention provides liquid cleanser compositions which contain fatty acyl isethionates surfactant products having at least 10 wt. % free fatty acid and/or fatty acid soap as the primary surfactant at a level at least 40 wt. % of total fatty acyl isethionate and synthetic cosurfactants in the liquid composition. The key is use of 10% to 60% glycerin and/or sorbitol which has been found, quite unpredictably, to stabilize compositions containing products of such high fatty acid and/or fatty acid soap content.
