  • Applications

    28-Hydroxy-7-octacosanone, CAS 138416-85-0, is a long-chain hydroxy ketone that is typically used in fragrance and cosmetic applications as an odorant and potential fixative; it may be used as a fragrance ingredient or aromatic intermediate in perfumery and personal care formulations. It can serve as a synthesis intermediate in industrial manufacturing for specialty chemicals, including polymers, surfactants, and lubricant-related products. The compound’s long-chain hydrophobic character and functional groups make it relevant as a formulation component in coatings and inks to influence texture or gloss. It may also be used as an intermediate or building block for derivatives employed in household products or cleaners, offering fragrance and performance attributes. Subject to local regulations and formulation limits.
