2-METHYL-4-(2,6,6-TRIMETHYL-2-CYCLOHEXENYL)-3-BUTENAL.

Optional CAS 58102-02-6 / PERFUMING

A specialized fragrance molecule from the ionone family that delivers violet and floral notes while masking undesirable base odors in skincare formulations. Beyond its olfactory function, this terpenoid compound provides minor skin-conditioning benefits through its lipophilic structure that can temporarily integrate into the skin's lipid barrier.
