MAGNESIUM ALGINATE

Safety grade: A

Magnesium alginate is a natural thickener derived from brown seaweed that helps create a smooth, gel-like texture in cosmetic products. It works like a sponge to absorb water and hold ingredients together.

This ingredient thickens cosmetic formulas, stabilizes emulsions to prevent separation, and helps bind ingredients together while creating a pleasant, smooth texture on skin.
