Aluminum Tristearate

What Aluminum Tristearate is & what it does

Aluminum Tristearate is the aluminum salt of stearic acid, a metallic soap commonly used as a thickener, viscosity controller, and surface treatment for powders and pigments. In sunscreens and color cosmetics it helps coat mineral particles so they disperse evenly and feel smoother. It also contributes to the texture and stability of anhydrous and emulsion systems. It is generally considered a well-tolerated formulation aid used at low levels.
