  • Applications

    Cylindrin (CAS 17904-55-1) is typically viewed as an intermediate in chemical synthesis and may be used as a solvent or processing aid in industrial manufacturing; it can function as a plasticizer or stabilizer in polymer/plastics formulations and may be considered for use in the formulation of coatings or films; it may be evaluated as a fragrance ingredient or odorant, potentially as a fixative in perfumery; it can be considered for use in cosmetics/personal care products or cleaning formulations, subject to local regulations and formulation limits.
