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.

Methoxy benzophenone Sulfonic Acid

Methoxy Benzophenone Sulfonic Acid is a water-soluble UV filter widely used in sunscreen and cosmetic formulations. It absorbs ultraviolet (UV) radiation, primarily in the UVB range, protecting skin and products from harmful effects of sun exposure. This compound appears as a white to off-white powder or crystalline solid and is valued for its photostability and broad-spectrum UV protection.
