Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
An unsaturated fatty alcohol providing a citrus-rose fragrance, generally considered safe in cosmetics at low concentrations.
3-Decenol is an unsaturated primary alcohol with a citrus and rose-like odor profile, used as a fragrance ingredient in cosmetic formulations. Unsaturated alcohols are generally less sensitizing than their aldehyde counterparts. The compound is listed in CosIng with no restrictions. However, the presence of a double bond makes it susceptible to oxidation, which could produce allergenic by-products over time in stored products.
