SODIUM CARBOXYMETHYL STARCH

Modified Starch

Safety grade: A

This is a starch derived from plants (like corn or potatoes) that has been chemically modified to help products stay mixed together and maintain a smooth, creamy texture. It acts like a thickener and stabilizer that keeps ingredients from separating.

It holds the different ingredients in a cosmetic product together, thickens the formula, creates a protective film on skin, and prevents the product from separating or breaking down over time.
