Applications & Use Cases
- ▸ Primary UVB-absorbing active in sunscreens, daily-wear facial moisturizers, and color cosmetics, where it is dosed to deliver a target SPF contribution.
- ▸ Photostabilizing UV filter in lip balms, foundations, and after-sun formulations to protect both skin and other light-sensitive ingredients.
- ▸ Light-stabilizer and UV absorber in clear coatings, plastics, and polymer films to reduce photodegradation, yellowing, and surface chalking.
- ▸ Oil-soluble UV screen incorporated into the oil phase of emulsions and anhydrous sticks, providing emollient-compatible film formation on substrate.
- ▸ Specialty additive in adhesives and printing inks where protection of pigments and resins from UVB-induced fading is required.
