  • Applications

    Maltal (CAS 32447-71-5) is typically used as an organic synthesis intermediate and may function as a solvent or processing additive in industrial manufacturing; in perfumery and fragrances it is considered an odorant or fragrance component with potential use as a fixative; in cosmetics/personal care it may be explored as a fragrance ingredient or formulation aid; in household cleaning products it can serve as a scent additive or solvent; in coatings, inks, and plastics processing it can function as a processing solvent or auxiliary additive; and in polymer manufacturing it may act as a reactive intermediate or synthesis aid, subject to formulation limits and local regulations.
