  • Applications

    Longistyline A (CAS 64095-60-9) is typically regarded as an organic chemical intermediate for synthesis; it may be used as a solvent or co-solvent in formulations and production processes; it is commonly evaluated for applications in polymers/plastics as a processing aid or stabilizer; in coatings and inks as a handling aid or additive component; in perfumery/fragrance and cosmetics/personal care as a fragrance ingredient or solvent; and in cleaning or household formulations as a solvent or additive. Its use is subject to local regulations and formulation limits.
