STEARONE

Safety grade: A

Stearone is a waxy, fatty substance derived from stearic acid that helps control how thick or thin a product feels. It works behind the scenes to give creams and lotions their smooth, easy-to-apply texture.

This ingredient thickens cosmetic formulas and helps stabilize their consistency, ensuring products spread smoothly and feel pleasant on the skin.
