About
A vinyl-substituted cyclohexylmethyl acetate fragrance ingredient. The dual vinyl groups make it oxidation-prone — antioxidant protection is essential.
Trimethyl-3-methylvinyl-4-vinylcyclohexylmethyl acetate (CAS 84434-64-0) is a highly functionalised cyclohexyl acetate fragrance captive with two vinyl (C=C) substituents. These unsaturated groups make the molecule especially prone to auto-oxidation and peroxide formation, with corresponding sensitizer risk. Used in very low % in perfumery. Public safety documentation is thin and managed via RIFM. No EU Annex II listing.
Skin benefits
- Complex fragrance woody/floral note
