About

1-Vinylimidazole is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

1-Vinylimidazole (CAS 1072-63-5) is a vinyl-substituted imidazole compound used as a monomer in the synthesis of vinylimidazole copolymers for cosmetic applications. As a reactive monomer, residual 1-vinylimidazole in the final polymer must be minimised. The SCCS has reviewed vinylimidazole polymers and monomers, noting that residual monomers must be below specified limits. The substance itself is not specifically listed in EU Annex II or III but requires careful handling during manufacturing. In the finished polymer form, it is considered safe.

Known concerns

  • Skin and eye irritation from monomer
  • Residual monomer must be minimised in polymers
  • Requires careful manufacturing controls
