Sorbitan Isostearate Bon Cleansing Agent No known benefits Sorbitan Isostearate at a glance Similar to the liquid fatty acid isostearic acid Works as a mild cleansing agent and emulsifier Helps stabilise water-in-oil formulas Not prone to breaking down when exposed to air 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 favour (Paula’s Choice Skincare uses the plant-derived form). Amounts as low as 2% can be used to stabilise 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.
