  • Applications

    Di-tert-butyl hydroxybenzylidene camphor is commonly used as a UV-absorbing stabilizer in cosmetics and personal care formulations, providing protection against UVA and UVB radiation; it is also employed as a photostabilizer in polymers and plastics, helping to improve outdoor color stability and material durability; in coatings and inks, it functions as a UV filter to retard photodegradation and yellowing of exposed surfaces; it can be incorporated into adhesives and sealants to enhance UV stability of the polymer phase; additional applications include use in household products and in electronics-related plastics and packaging resins to mitigate sunlight-induced degradation, subject to local regulations and formulation limits.
