  • Applications

    4,8-Dimethylnonan-1-ol (CAS 33933-80-1) is a branched 11-carbon aliphatic alcohol used across several industrial and cosmetic applications; in perfumery it serves as a fragrance ingredient and can function as a fixative to help bond and prolong aroma; in cosmetics and personal care it acts as an emollient and can serve as a solvent or co-solvent for other formulation ingredients; industrially, it is employed as an intermediate for the synthesis of fragrance esters and related compounds and may also serve as a solvent in formulations; in polymer processing, it can act as a plasticizer or processing aid to improve flexibility and lubrication; and in coatings or inks, it may be used as a solvent or carrier for formulation components.
