  1. Application field

Avobenzone, butyl methoxydibenzoyl methane, belongs to the benzophenone ultraviolet absorber, and it is also a very important organic synthesis intermediate.

Avobezone, Butyl methoxydibenzoyl methane, is a synthetic ultraviolet absorber. It is a good UV-A (>320nm) type ultraviolet absorber, which can block the full band (320~400nm) of UVA and is an efficient and broad spectrum. Oil-soluble UVA filter, compounded with other UVB sunscreens, can provide all UVA and UVB protection, used to prevent photo-induced skin cancer.

Avobenzone, butyl methoxydibenzoyl methane, also known as Parsol 1789, is a highly effective broad-spectrum oil-soluble UVA filter. Long-term use can effectively reduce wrinkles, stains, rough skin and other problems, and can prevent skin cancer. It is mainly used in cosmetics sunscreen, sunscreen and other products, and can also be used as a stabilizer to prevent photolysis of cosmetics and perfume.

Avobenzone, butyl methoxydibenzoyl methane, is a sunscreen blocker. Avobenzone is a topical, broad range UV protector and blocks UVA I, UVA II, and UVB wavelengths, thereby limiting the impact of UV rays on skin.

Avobenzone, butyl methoxydibenzoyl methane, acts as a sunscreen and UV filter. It offers broad spectrum protection against UV radiation. It is used as a photo-antioxidant to protect products from photo-oxidation.
