About
A synthetic polymer used mostly for texture, film formation, or formula stability rather than as a true skincare active. The main worry is usually residual monomers, not deep skin absorption.
Bis-HEMA Poly(1,4-Butanediol)-14/PEG-2/PPG-3/IPDI Copolymer is a copolymer of poly(1,4-butanediol)-14, PEG-2, PPG-3 and Isophorone Diisocyanate (IPDI), end-capped with HEMA. High-molecular-weight polymers are usually used for film formation, texture, or wear and are expected to have limited penetration through intact skin. No major hazard flags are listed in the batch data, so the main uncertainty is limited ingredient-specific human data.
Function
Known concerns
- Residual reactive monomers may be sensitising if poorly controlled
