About

A hydroxypropyl methacrylate (HPMA) carbamate derivative used as a film-forming and protective polymer in advanced cosmetic formulations, particularly nail and skin coating applications.

Bis-HPMA Pentamethylene Dicarbamate is a diurethane dimethacrylate compound related to the family of monomers used in dental composite resins and nail gel formulations. The HPMA moiety provides methacrylate functionality for free-radical polymerisation, while the pentamethylene dicarbamate backbone provides flexibility and chemical resistance. In cosmetic applications, it is used in nail coating and protective film formulations. The carbamate functional group is considered to have low systemic toxicity. However, as with all methacrylate monomers, residual monomer content must be controlled and sensitisation potential assessed. No specific EU restrictions apply to this compound class beyond general cosmetic safety.

Known concerns

  • Carbamate functional group - generally low toxicity
  • Specialty polymer for dental/medical materials
  • Limited cosmetic-specific safety data
