About

Dihydroeugenol is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Dihydroeugenol is produced by catalytic hydrogenation of eugenol, reducing its allyl side chain. It retains the phenylpropene structure of eugenol and is used as a fragrance ingredient in perfumery. Eugenol and related methoxyallylbenzene derivatives are documented skin sensitizers. While dihydroeugenol is not individually listed in EU Annex III part 1, it falls within the broader class of fragrance allergens subject to the 0.01% declaration threshold under Regulation (EC) No 1223/2009 Article 19. IFRA limits apply to eugenol derivatives in fragrance applications.

Known concerns

  • Documented skin sensitizer (fragrance allergen class)
  • Cross-reactivity with other phenylpropenes
  • Requires declaration per EU fragrance allergen rules
