UV Absorber BP-4 (CAS 4065-45-6) is a kind of excellent water-soluble ultraviolet absorber, which is generally used for water-soluble cosmetics to resist solarization and also as UV Absorbers for other water-soluble printing ink and dopes,  and highly effective as an ultraviolet light absorber (UV screen) for these products.

Storage: UV Absorber BP-4 (CAS 4065-45-6) should be stored in a closed system and be kept in a dark place without any light exposure.

Transportation: Avoid upside down, sunlight, wet and crash , avoid damage the package. UV Absorber BP-4 (CAS 4065-45-6)can be safely handled without any irritation caused to the skin.

 

1. Benzophenone can be used as a photo initiator in UV-curing applications such as inks, imaging, and clear coatings in the printing industry.
2. Benzophenone prevents ultraviolet (UV) light from damaging scents and colors in products such as perfumes and soaps.
3. It can also be added to the plastic packaging as a UV blocker. Its use allows manufacturers to package the product in clear glass or plastic. Without it, opaque or dark packaging would be required.
 

Mainly used for water soluble in cosmetics as a resistance to bask in sunscreen, can also be used in other water-soluble ink, paint, etc for uv absorber;As anti-ultraviolet finishing agent for cotton fabric, polyester fiber has good anti aging and softening effect.A broad-spectrum UV absorber, absorption with high efficiency, non-toxic side effects, no teratogenicity, optical, thermal stability is good wait for an advantage, it also can absorb uv-a and UV - B, a kind of sunscreen, use frequency is higher in the United States and Europe, widely used in sun lotion, cream, honey, latex, oil and other sunscreen cosmetics as anti-ultraviolet finishing agent, the cotton fabric, polyester fiber has good anti aging and softening effect. Mainly used for water soluble in cosmetics as a resistance to bask in sunscreen, can also be used in other water-soluble ink, paint, etc for uv absorber
