POTASSIUM ALGINATE

Safety grade: A

Potassium alginate is a natural thickening ingredient derived from brown seaweed that helps give cosmetic products a smooth, gel-like texture. It works like a natural glue to keep product ingredients mixed together and prevents separation.

This ingredient thickens products, stabilizes emulsions to keep oil and water from separating, and helps bind ingredients together for a better texture and longer shelf life.
