Magnesium Stearate
Magnesium stearate is a fine white powder primarily used in cosmetics as an anti-caking agent, lubricant, and emulsifier. It helps to prevent ingredients from sticking together, improves the spreadability of products, and can enhance adhesion to the skin. It is often found in pressed powders and solid formulations.
