About

3-methyl-5-propyl-2-cyclohexenone is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This cyclohexenone derivative carries hazard statements H315 (skin irritation) and H319 (eye irritation). The alpha,beta-unsaturated ketone system contributes to both its fragrance character and irritancy potential. Typical IFRA guidelines for cyclic enones recommend use level restrictions, and EU regulations require proper label disclosure of this fragrance allergen class in finished cosmetic products.
