About
3-DODECENAL is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
3-Dodecenal (dodec-3-enal) is an unsaturated aliphatic aldehyde fragrance ingredient contributing powerful citrus, green, and waxy notes. Like most alpha-beta unsaturated aldehydes, it has sensitisation potential that limits its use to low concentrations, particularly in leave-on products. IFRA guidelines restrict maximum use levels, and EU allergen labelling requirements apply at specified concentrations.
Skin benefits
- Contributes powerful fresh, citrus-green fragrance notes
Known concerns
- Skin sensitisation potential as an aldehyde
- IFRA restrictions limit concentration in leave-on cosmetic products
- Unsaturated structure contributes to oxidation concern in formulations
