Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (MBBT) is a broad-spectrum organic UV filter available in particulate form. It works by absorbing and scattering both UVA and UVB radiation, converting harmful UV energy into harmless heat. Its high photostability provides long-lasting protection against photoaging and UV-induced skin damage while supporting overall sunscreen performance.

Absorbing both UVA (320–400 nm) and UVB (280–320 nm) rays.
