What it is
Cetyl Palmitate is a waxy ester formed from cetyl alcohol and palmitic acid, and is a key component of natural spermaceti substitutes. In formulas it provides body and structure, thickening the oil phase and contributing to a smooth, cushioned emollient feel. It is widely used in stick and cream sunscreens to help set texture and stabilize emulsions.
Safety & warnings
Cetyl palmitate is generally well tolerated and considered low in irritation potential. As a fatty wax ester it has some pore-clogging potential and is often rated as mildly to moderately comedogenic, which acne-prone users may wish to consider.
Origin & sourcing
Produced by esterifying cetyl alcohol with palmitic acid; the starting materials are commonly derived from plant oils.
