What is Bisoctrizole?
Bisoctrizole (CAS 103597-45-1), also marketed as Tinosorb M and MBBT, is a broad-spectrum UV filter that absorbs and reflects both UVA and UVB radiation.
Where is Bisoctrizole used?
- Personal care and industrial formulations: protection from photodegradation
- Sunscreen and cosmetics: hybrid UV filter for broad-spectrum SPF at low use levels
- Coatings and polymers: prevention of UV-induced yellowing, chalking and mechanical degradation
- Adhesives, sealants and elastomers: polymer matrix stabilisation against prolonged UV exposure
- Plastic compounders use it in films, sheets and molded parts for resistance.
Commercial specifications
- Micronized aqueous dispersion, the standard cosmetic form
- Powder and suspension variants for industrial uses
- Drums and IBCs; dispersion concentrations commonly around 50%
