POLYGLYCERYL-3 DIHYDROXY STEARATE

Safety grade: A

This is a gentle emulsifier made by combining glycerin (a natural humectant) with stearic acid (a fatty acid). It helps mix oil and water together in cosmetic products so they blend smoothly instead of separating.

This emulsifier blends oil and water-based ingredients together in cosmetics, creating a stable, uniform product texture while being mild enough for sensitive skin.
