What is Aluminum Stearate?

Aluminum Stearate is a fine, white powder that is derived from stearic acid, a fatty acid commonly found in animal and vegetable fats. It is created through the reaction of stearic acid with aluminum salts.

This ingredient is primarily used as a thickener and stabilizer in various cosmetic and industrial products, including sunscreens and paints. The health evidence on its safety is limited, but it is generally considered safe in cosmetic applications. However, inhalation in industrial settings may pose health risks.
