About

A fragrance ketone with skin sensitization and aquatic toxicity warnings, requiring careful handling.

Dimethylcyclohexenyl 3-butenyl ketone is a synthetic fragrance ingredient bearing both a skin sensitization warning (H317) and aquatic toxicity classification (H411) under GHS. This cyclohexenyl ketone is structurally related to ionone fragrance compounds. The dual hazard classification means EU regulations impose restrictions on its use concentration in cosmetic products left on the skin. Caution is warranted in leave-on formulations.
