Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer

TL;DR. A synthetic film-forming polymer used to create a flexible, water-resistant film and improve wear, payoff, and texture in color cosmetics, sunscreens, and skin-care formulas.

What does Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer do in a cosmetic formula?

A synthetic film-forming polymer used to create a flexible, water-resistant film and improve wear, payoff, and texture in color cosmetics, sunscreens, and skin-care formulas.

Is Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer clean?

From a clean-beauty perspective, it has low direct irritation potential because it is a high-molecular-weight polymer, but it can face restricted-list friction as a synthetic it. Scrutiny usually centers on polymer persistence and residual monomer controls rather than acute skin tolerance.

Is Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer sustainable?

This material is primarily petrochemical-derived, with some potential biobased contribution depending on the glycerin source. Its crosslinked polymer structure is not considered readily biodegradable, so environmental persistence is the main sustainability drawback.

Is Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer COSMOS-approved?

It is generally not aligned with COSMOS-natural or COSMOS-organic standards because it is a synthetic crosslinked polymer. It fits Green Chemistry weakly, since it provides performance at low use levels but has limited renewable sourcing and biodegradability advantages.

How does Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer work chemically?

The molecule is a crosslinked polyester network built from diol, diacid, and polyol monomers, giving it film-forming and texture-modifying behavior rather than classic small-molecule activity. It is typically used at low single-digit percentages, is broadly stable across normal cosmetic pH ranges, and is co-formulated with oils, pigments, UV filters, or waxes to improve film integrity and wear.
