About
A urethane/urea polymer built from lysine, hexanediol and isophorone diisocyanate that forms a flexible film on skin, this ingredient has no significant EU cosmetic restrictions.
Polyurethane-92 is a multi-step synthesized urethane/urea copolymer using lysine as a chain extender and isophorone diisocyanate (IPDI) as the diisocyanate component, neutralized with sodium carbonate. EU REACH recognizes high分子量 polymers (>1000 Da) as unlikely to penetrate skin; no specific restriction exists in EU cosmetic regulations for this polymer class. The polymer provides substantive film-forming properties without the concerns associated with residual monomer content seen in lower分子量 urethanes.
