Product Description

Product Description

Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (Tinosorb M) is a next-generation UV filter renowned for its unparalleled broad-spectrum protection (280-400nm). As a micronized, photostable powder, it provides both UVA and UVB defense while enhancing formulation stability—making it ideal for high-SPF sunscreens, anti-aging skincare, and daily wear cosmetics.
It is insoluble in water and exists in the form of organic microfine particles, which can improve the efficacy of UV protection. It converts the absorbed UV energy into heat energy, thereby protecting the skin from UV-induced damage.
  • ✔ Full-Spectrum Shield – Blocks UVA (aging) + UVB (burning) rays more effectively.
  • ✔ Exceptional Photostability – Resists degradation under sunlight for long-lasting protection.
  • ✔ Elegant Formulations – Minimizes white cast when properly dispersed.
  • ✔ Synergistic Performance – Boosts SPF when paired with other filters.
