Trimethylpentanediol/Adipic Acid Copolymer

What Trimethylpentanediol/Adipic Acid Copolymer is & what it does

Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer is a synthetic film-forming polymer made by crosslinking trimethylpentanediol, adipic acid, and glycerin. In skincare and sunscreen formulas it acts as a film former and texture modifier, helping spread the product evenly and leave a smooth, flexible finish on the skin. A notable property is that it can improve the water resistance and wear of a film, which is useful in long-lasting and sunscreen products.
