Description
Dioxybenzone, also known as Benzophenone-8, UV absorber BP-8, UV absorber UV-24, 2,2'-Dihydroxy-4-methoxybenzophenone, is a high-efficiency, wide-band UV absorber. Dioxybenzone is a benzophenone containing two ortho hydroxyl groups. It has the strongest ability to absorb ultraviolet light. Dioxybenzone has a strong absorption effect on ultraviolet light in the wavelength range of 330 to 370 nm. It can absorb ultraviolet light with a maximum wavelength of 400 nm. Its disadvantage is that it also absorbs some visible light, making the product slightly yellow. Dioxybenzone can effectively protect products from ultraviolet radiation, and is widely used in plastic products such as polyvinyl chloride, ABS resin, polyurethane, melamine resin, cellulose resin, etc. It also has good light stabilization effect in paints and coatings, is also used in sunscreen creams and other sunscreen cosmetics.
