Tinosorb M

What is Tinosorb M?

Tinosorb M, chemically known as methylene bis-benzotriazolyl tetramethylbutylphenol, is a synthetic hybrid UV filter developed for cosmetic formulations. It belongs to the category of broad-spectrum sunscreen agents used primarily in sun protection products like lotions, creams, and sprays. This ingredient functions through a dual mechanism: as an organic absorber, it captures UVA and UVB radiation, converting it into harmless heat; simultaneously, its microfine particulate structure scatters and reflects UV light away from the skin. Its polymeric nature enhances photostability, preventing breakdown under sunlight exposure, and contributes to water resistance in formulations. Commonly incorporated at effective levels in daily skincare to shield against sun-induced damage.
