About

A synthetic diketone compound with potential use as a UV filter or antioxidant agent. The methoxyphenyl groups suggest aromatic character, and while not broadly restricted, its safety data in cosmetics remains limited.

Bis-Methoxyphenyl Heptanedione is a synthetic organic compound featuring two methoxyphenyl groups attached to a heptanedione backbone. Its structure suggests it may function as a UV absorber or antioxidant in cosmetic formulations, though confirmed cosmetic usage data is limited. The diketone moiety can participate in keto-enol tautomerization, potentially affecting reactivity. With only one relevant CAS number reference and limited published toxicological data, a cautious safety approach is warranted. No EU restrictions found, but usage in leave-on products should be carefully evaluated.

Skin benefits

  • May provide antioxidant protection
  • Possibly functions as a UV filter agent

Known concerns

  • Limited toxicological data available
  • Potential for skin sensitization with leave-on use
  • Structure alerts for potential reactivity (diketone)
