- Application field
Benzophenone-1 is a powder polymer additive applicable to polyolefine, poyvinyl chlornamee, polystyrene etc as a stabilizer with the incorporation of 0.1% to0.5% (based on polymer weight) required.
Benzophenone-1 is an ultraviolet stabilizer that resists color changes when the dry film is exposed to sunlight.
Benzophenone-1 is effective sunscreen with absorption ranging from 270 to 350 nm. Benzophenone-1 can be employed to improve light stability of cosmetic products such as alcoholic fragrances, gels, colors, nail enamels and liquid detergents.
Benzophenone-1 is used as a UV absorber to protect cosmetics and personal care products from deterioration by absorbing, reflecting, or scattering UV rays. In cosmetics and personal care products, Benzophenone-1 is used mostly in the formulation of nail polishes and enamels, but can also be used in bath products, makeup products, hair products, sunscreens and skin care products.
Recommended use level of Benzophenone-1: 0.05-0.5%.
