  • Applications

    2-Cyclohexen-1-ol, 5-methylene-6-(1-methylethenyl)-, acetate, (1S-cis)- (CAS 32151-09-0) is primarily used as an aroma compound and intermediate in fragrance chemistry, where it can act as an odorant and contribute green, leafy, or woody notes, sometimes serving as a fixative to extend scent longevity. In cosmetics and personal care, it is applicable as a fragrance component in formulations for creams, lotions and bath products. It may also appear in household products like air fresheners and cleaners for scent enhancement. Additionally, it is evaluated as an intermediate in the synthesis of other aroma chemicals and specialty polymers, and may be considered for flavor/aroma applications in foods where permitted by regulation. Use is subject to local regulations and formulation limits.
