HDI/Trimethylol Hexyllactone Crosspolymer

A synthetic polymer used to create film-forming serums and gels. It is stable, non-irritating, and widely used in cosmetic formulations to improve texture and adherence without toxicological concerns.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
