  • Applications

    Ethyl methoxycinnamate (CAS 24393-56-4) is an aromatic cinnamate ester with UV‑B absorption and a sweet balsamic scent, used as a UV absorber and photostabilizer in cosmetics/personal care (e.g., to support sunscreen and hair/skin-care formulations) and as a floral–vanillic fragrance/flavor modifier in perfumes, soaps, and flavorings; in materials it helps mitigate UV‑induced yellowing and degradation of polymers, coatings, and printing inks; in synthesis it serves as a building block for pharma, agrochemical, and specialty chemicals; in pharmacognosy it is a marker constituent of Kaempferia galanga extracts and a common analytical reference standard, and has been studied for anti-inflammatory, antimicrobial, and insecticidal/repellent potential as well as an alternative UV filter, subject to market-specific regulations.
