Oxybenzone, UV-9

Light yellow crystalline powder, soluble in ethanol, acetone and other organic solvents, insoluble in water.

Oxybenzone is an organic compound used in sunscreens. Oxybenzone is used as an ingredient in sunscreen and other cosmetics because it absorbs UVB and short-wave UVA (ultraviolet) rays. Oxybenzone was one of the first compounds incorporated into sunscreen formulations to offer enhanced UVA protection because its absorption spectrum extends to less than 350 nm.

This product can also be used as ultraviolet light absorber and stabilizer, for paints, and synthetic rubber.  For the broad-spectrum UV absorbers, with high absorption rate, non-toxic, non-teratogenic effect, light, thermal stability. In addition, it is usually used for PVC and unsaturated polyester and many other fields, because UV-9 has good compatibility with many kinds of plastics and resins.

Suitable for polyvinyl chloride, polyvinylidene chloride, polymethyl methacrylate , unsaturated polyester, ABS resin and cellulose resin and other plastics, the maximum absorption wavelength range of 280-340 nm, the general amount of 0.1-1.5%, good thermal stability, does not decompose at 200 ℃. This product almost absorb no visible light, it applies to light-colored transparent products.
