About
A polymer combining acrylic and imidazole units that provides antimicrobial protection in cosmetic formulations.
Ammonium Acrylates/Vinyl Imidazole Copolymer is a cationic copolymer formed from vinyl imidazole and acrylic acid/methacrylic acid monomers, neutralized with ammonium. The imidazole groups provide antimicrobial activity while the acrylate backbone gives film-forming properties. PubChem safety score of 82 supports a good profile. As a fully polymerized material, residual monomer levels are the main concern (acrylic acid and vinyl imidazole monomers are irritants). No GHS hazards or EU restrictions.
