C18-38 Alkyl Hydroxystearoyl Stearate Description

C18-38 alkyl hydroxystearoyl stearate is a skin conditioning emollient derived from the fatty acid stearic acid. It is added to products both to improve texture and spreadability as well as protect skin from moisture loss. It’s also capable of stabilizing emulsions, working to keep the oil and water phases from separating.

Depending on the formula it’s used in (lotion, cream, balm, etc.), usage levels of c18-38 hydroxystearoyl stearate range from 1-15%. This ingredient may be plant-derived, animal-derived (less common), or synthetic.
