An α,β-unsaturated ketone fragrance that shows moderate irritation potential and requires typical IFRA restriction guidelines for cosmetic application.

This unsaturated ketone has a PubChem safety score of 55 indicating moderate concern. The structural feature of an alpha,beta-unsaturated carbonyl system is associated with both fragrance activity and sensitization potential.
