  • Applications

    Dihydrophytol (CAS 645-72-7) is a saturated diterpene alcohol related to phytol. In perfumery it is used as a fragrance ingredient and can act as a modest fixative to help extend fragrance longevity. In cosmetics and personal care, it may be employed as a fragrance component. In household products, it is used as a fragrance additive in cleaners and home care products to impart character and longevity. In industrial manufacturing, it may be evaluated as an intermediate in fragrance synthesis or as a specialty solvent for fragrance-related formulations. Subject to local regulations and formulation limits.
