  • Applications

    Heleniamarin (CAS 66607-74-7) has industrial uses as a chemical synthesis intermediate and as a fragrance-related odorant; it may serve as a solvent or co-solvent in formulation work; acts as a processing aid or stabilizer in coatings, inks, and polymer systems; and can appear in household cleaning products and cosmetics/personal care formulations where an aroma contribution is desired, subject to local regulations and formulation limits.
