ALUMINUM MYRISTATES/PALMITATES.

Valuable / ANTICAKING, EMULSION STABILISING, OPACIFYING, VISCOSITY CONTROLLING

Aluminum Myristates/Palmitates is a physical texturizer derived from fatty acids, serving as an anticaking agent and emulsion stabilizer. It enhances formula aesthetics and stability, contributing to a smooth application.

Summary

anticaking emulsion stabilising viscosity controlling opacifying

Science

Mechanism of Action

This aluminum salt of fatty acids primarily improves powder flow and prevents clumping. It stabilizes oil-in-water or water-in-oil emulsions and increases viscosity in anhydrous systems by forming a gel-like structure.

Dusting Analysis

Not commonly dusted

While aluminum inhalation concerns exist, cosmetic applications typically use particle sizes greater than 10 µm, which are generally non-respirable.
