About 3,5-DIMETHYLCYCLOHEXENE-1-METHANOL
A cyclohexene-derived primary alcohol with gem-dimethyl substitution, used as a fragrance ingredient. Carries an eye irritation hazard and is subject to typical fragrance material sensitization considerations.
Detailed Analysis
3,5-Dimethylcyclohexene-1-Methañol is a cyclohexene carbinol with gem-dimethyl substitution at positions 3 and 5. The allylic alcohol structure (with the hydroxymethyl group at C1 adjacent to the double bond between C1 and C2) confers reactivity typical of such systems. The H319 classification indicates eye irritation potential. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation, suggesting permitted cosmetic use at normal fragrance concentrations.
