  • Applications

    2-Naphthalenol, decahydro-5,5,8a-trimethyl-, 2-acetate (CAS 24238-95-7) is an acetate ester of a hydrogenated naphthol framework commonly used as an odorant/fragrance ingredient and as an intermediate in fragrance synthesis. In cosmetics and personal care formulations, it is used to impart or adjust fragrance and may function as an odorant or fragrance fixative in fragrance programs. In coatings and inks, this compound can be included as a fragrance additive to provide characteristic scents in surface finishes and printed products. In polymers and plastics, it may serve as an intermediate or fragrance modifier within resin systems, helping to integrate scent with the material. It can also find use in household products such as cleaners or detergents to add fragrance. Use is subject to local regulations and formulation limits.
