  • Applications

    3-(4'-Methylbenzylidene)camphor (CAS 36861-47-9) is primarily used as a UV absorber in cosmetics and personal care, especially in sunscreen formulations and light-stable skin-care products to protect against UVA/UVB exposure; it is also evaluated as an intermediate for camphor-derived and benzylidene camphor derivatives in organic synthesis; in coatings, inks, and polymer formulations it can act as a UV-stabilizing additive to mitigate photodegradation; and in industrial manufacturing it may serve as a starting material for related UV-absorbing agents or specialty intermediates.
