About

A texture-building polymer that improves slip, film formation, or thickness more than it acts as a true skin treatment.

This ingredient is a silicone resin powder used mainly to modify texture, slip, film formation, or water retention in a formula. Large polymers usually have low skin penetration, so topical safety concerns are mostly limited to mild irritation or residual manufacturing impurities.

Function

BULKING

Known concerns

  • Low but not zero irritation risk in very sensitive skin
