About
A urethane copolymer film-former for nail and skin applications, made from HPMA-capped diethylene glycol/adipate polymer with IPDI.
A urethane polymer produced by condensing Diethylene Glycol and Adipic Acid, reacting with Isophorone Diisocyanate (IPDI), and end-capping with Hydroxypropyl Methacrylate (HPMA). Similar in structure to Bis-HEMA copolymers but using diethylene glycol rather than glycol/TMP. High molecular weight limits skin penetration. Not restricted in EU Annex II or III; HPMA-capped polymers are standard in nail cosmetic formulations. PubChem safety score: 75.
