Bemotrizinol Cas No: 187393-00-6 is an oil-soluble organic compound that is added to sunscreens to absorb UV rays. Bemotrizinol is a broad-spectrum UV absorber, absorbing UVB as well as UVA rays. It has two absorption peaks at 310 and 340 nm. It is highly photostable. Even after 50 MEDs (minimal erythemal doses) 98.4% remains intact. It helps prevent the photodegradation of other sunscreen actives like avobenzone. Furthermore, its presense can at least partially protect less photostable UV blockers (e.g. UVA-blocker avobenzone) from degradation. It is approved in Europe and Australia but not in the USA. Unlike some other organic sunscreen agents, bemotrizinol has not been shown to have hormone-like (estrogenic) effects in cell cultures. Bemotrizinol appears to be relatively non-toxic and rarely causes skin irritation. However, as with many synthetic chemicals, it is unclear whether bemotrizinol may produce low-level skin damage and/or systemic effects with long-term use. ZXCHEM GROUP

Ethylhexyl Triazone Cas No: 88122-99-0 is an organic compound used in sunscreens to absorb UVB radiation. It has an absorption maximum of 314 nm. Ethylhexyl triazone has a good affinity for skin keratin, making the formula particularly water resistant. High SPF can be achieved by using small concentrations in sunscreens. ZXCHEM GROUP

Benzophenone 4 Cas No: 4065-45-6 is a white or pale yellow powder. It is used in bath products, makeup products, hair products, sunscreens and skin care products to protect cosmetics and personal care products from deterioration by absorbing, reflecting, or scattering UV rays. When used as a sunscreen ingredient, Benzophenone-4 protects the skin from UV rays. ZXCHEM GROUP
