About

A synthetic texture or film-forming polymer that mainly changes feel and wear rather than skin biology.

TRIMETHYLSILOXY/POLYMETHYLSILSESQUIOXANE is a high-molecular-weight synthetic polymer used for film formation, thickening, slip, or product stability. These large materials usually have low skin penetration and low direct toxicology concern in finished cosmetics. The main limitation is that they are mostly functional formula aids rather than ingredients with meaningful skin benefits.
