Avobenzone

Avobenzone (chemical name: Butyl Methoxydibenzoylmethane) is an oil-soluble organic compound widely used as a UVA filter in sunscreen formulations. It is valued for its ability to absorb a broad spectrum of ultraviolet A (UVA) rays (320–400 nm), protecting the skin from premature aging and damage caused by sun exposure. Avobenzone is often combined with other UV filters to provide broad-spectrum sun protection. It is a pale yellow liquid or crystalline powder, soluble in oils and alcohols but unstable in sunlight unless stabilized with other agents.
