Oxidized Starch Acetate
What Oxidized Starch Acetate is & what it does
Oxidized Starch Acetate is a chemically modified starch, made by oxidizing and acetylating a natural starch base such as corn or potato. In cosmetic and sunscreen formulas it acts as a texturizer and thickener, and it can lend a soft, dry, powder-like feel that helps reduce greasiness. Its film-forming nature can also help a product sit more evenly on the skin.

Is Oxidized Starch Acetate comedogenic?
