Wavelengths covered: about 280-400 nm, which covers both UVB and UVA ranges; peak protection at 303 nm and 358 nm.
Bisoctrizole is a light stabilizer in polymers and resins. It is majorly used as a UV filter in sunscreens and in photo-luminescent dyes for organic electronic based applications.
ChEBI: Bisoctrizole is a diarylmethane. It is a broad-spectrum organic UV filter that is marketed as Tinosorb M. It is a benzotriazole-based organic compound that absorbs, reflects, and scatters both UV-A and UV-B rays.

Bisoctrizole is a benzotriazole based additive that is used as an ultraviolet absorber (UVA). It reduces degradation of the polymeric material by absorbing the UV radiation and converting it to thermal heat. Bisoctrizole is often added to sunscreen formulations that It may protect skin against blue light and other environmental assaults.
Bisoctrizole appears to be relatively non-toxic and rarely causes skin irritation. As with many synthetic chemicals, whether bisoctrizole may produce low-level skin damage or systemic effects with long-term use is unclear. Considering that bisoctrizole is stable, poorly soluble, and minimally absorbed by the skin, the risks appear to be low. Still, more research on bisoctrizole safety is needed.
