Product Name:2-Hydroxy-4-methoxybenzophenone
English Name:2-Hydroxy-4-methoxybenzophenone
CAS No.:131-57-7
Aliases:Oxybenzone, Benzophenone-3, BP-3
Molecular Formula:C14H12O3
Physical Properties:White to off-white or light yellow crystalline powder with faint aromatic odor. Melting point 62-64°C, boiling point approx. 150°C, density 1.324 g/cm³, refractive index 1.595, flash point 140.5°C. Insoluble in water, readily soluble in ethanol, acetone, benzene and other organic solvents. Good stability to light and heat.
Uses:It is a benzophenone-type broad-spectrum UV absorber that effectively absorbs UV-A and UV-B bands, featuring high absorption efficiency, non-toxicity, no teratogenic effects, and good stability to light and heat. Approved by the US FDA as a Category I sunscreen agent, it is widely used in sunscreen cosmetics; it is also an excellent light stabilizer for polyethylene and other synthetic plastics at 0.5%-1.5% dosage, and can be used in paints, pigments, coatings, refined paraffin wax and other industrial fields.
