Sorbitan Isostearate Description
Sorbitan isostearate is a mild cleansing agent and emulsifier made by combining portions of fatty acid isostearic acid with the sugar ingredient sorbitol. It may be derived from plants, made synthetically, or animal-derived, although the latter form has fallen out of favor (Paula’s Choice Skincare uses the plant-derived form).Amounts as low as 2% can be used to stabilize emulsions, and its safety has been established in concentrations up to 25%, although sorbitan isostearate is rarely used above 10% concentration in skin care formulas.
