  • Applications

    1,1-Dimethoxycyclododecane (CAS 950-33-4) is a cyclic acetal of cyclododecane bearing two methoxy groups at C1; in industry it is typically considered a specialty solvent and processing aid, potentially used as a high-boiling solvent or carrier for fragrance oils in perfumery and cosmetics, and as a solvent or co-solvent in household products, coatings and inks, as well as cleaning formulations. It can also function as an intermediate in organic synthesis for producing specialty chemicals used in polymers/plastics. Its exact role depends on formulation needs and regulatory constraints.
