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.
