About this ingredient

Aluminum Stearate is a metallic salt formed from the reaction of aluminum and stearic acid, functioning as a multifunctional agent in cosmetic formulations. It acts as a thickener, anti-caking agent, and absorbent that improves texture, reduces shine, and enhances spreadability in powders and creams. It is particularly valued in oil-control and mattifying formulations due to its mild absorbent properties.
