Methylene Bis-Benzotriazolyl Tetramethylbutylphenol

Description

Methylene Bis-Benzotriazolyl Tetramethylbutylphenol, also known as Bisoctrizole or Tinosorb M, is an advanced broad-spectrum UV filter widely used in sunscreen formulations. This organic compound effectively protects against both UVA and UVB radiation, offering comprehensive photoprotection. Its large molecular size prevents skin penetration, reducing the risk of systemic absorption and potential irritation.

As a photostable ingredient, Methylene Bis-Benzotriazolyl Tetramethylbutylphenol maintains its efficacy even after prolonged sun exposure. It functions through both absorption and scattering mechanisms, enhancing its protective capabilities. This ingredient is particularly valuable in water-resistant formulations due to its low solubility in water.

In skincare products, it is typically used at concentrations between 1% and 10%, depending on the desired SPF level. Methylene Bis-Benzotriazolyl Tetramethylbutylphenol is often combined with other UV filters to achieve optimal protection and improve the overall aesthetics of sunscreen formulations. Its compatibility with various cosmetic ingredients makes it versatile for use in different product types, including lotions, creams, and sprays. This UV filter is approved for use in many countries, including those in the European Union, Australia, and Japan.
