Sodium Benzotriazolyl Butylphenol Sulfonate
What is Sodium Benzotriazolyl Butylphenol Sulfonate?
Sodium Benzotriazolyl Butylphenol Sulfonate is a synthetic chemical compound belonging to the benzotriazole class of UV filters. It features a sulfonate group that enhances its solubility in water, distinguishing it from many oil-soluble UV absorbers. Primarily employed in sun care formulations like lotions, sprays, and gels, it functions by absorbing harmful ultraviolet B (UVB) radiation in the range of 280-320 nm. Upon absorption, the energy is converted into harmless heat, which dissipates without damaging the skin. This ingredient contributes to photostable, water-resistant products, making it suitable for extended sun exposure scenarios. Its chemical structure provides efficient UV protection without leaving a white residue, blending seamlessly into clear cosmetic bases.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Benefits
