52

Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Maleimide-functionalised diphenylacrylate UV chromophore intended as a sun-protection ingredient. The reactive maleimide moiety raises potential skin sensitisation concerns and the material lacks formal regulatory review.

Skin benefits

  • Designed as a novel UV-absorbing chromophore
  • Maleimide tether may enable substantivity to skin/hair proteins
  • Potentially broad UV-A absorption
  • Cyano diphenylacrylate is a known UV filter scaffold (octocrylene analogue)

Known concerns

  • Maleimide functional group is a strong Michael acceptor and protein binder, raising sensitization concerns
  • No SCCS opinion or Annex VI listing identified
  • Octocrylene-related impurity benzophenone is a known concern in analogous filters
  • Limited toxicology data publicly available
