  • Applications

    Isoamyl p-methoxycinnamate (CAS 71617-10-2) is the ester of p-methoxycinnamic acid with isoamyl alcohol. In cosmetic and personal care formulations, it may be used as a UV-absorbing agent or as a fragrance ingredient and fixative. In coatings and inks, it can function as a light-stabilizing component to help prevent color fading under light exposure. In the polymer and plastics sector, it may act as a UV stabilizer to protect plastics from photodegradation. It may also serve as an intermediate in the synthesis of cinnamate esters for industrial applications. These uses are subject to local regulations and formulation limits.
