BUTYL METHOXYDIBENZOYLMETHANE

Description

Butyl Methoxydibenzoylmethane, also known as Avobenzone, is a crucial ingredient in sunscreen formulations, renowned for its exceptional UVA protection capabilities. This organic compound belongs to the dibenzoylmethane class and is widely utilized in broad-spectrum sunscreens due to its ability to absorb a wide range of UV wavelengths, particularly in the UVA spectrum (320-400 nm).

The molecule's structure allows it to effectively convert harmful UV radiation into harmless heat, providing robust protection against premature skin aging and DNA damage. However, Avobenzone is photolabile, meaning it can degrade when exposed to sunlight, potentially reducing its efficacy over time. To counter this, it is often combined with photostabilizers like Octocrylene or Tinosorb S.

Butyl Methoxydibenzoylmethane is oil-soluble and typically used at concentrations of 2-3% in sunscreen formulations. While generally well-tolerated, it may cause irritation in some individuals with sensitive skin. Its global regulatory status varies, with approval for use in sunscreens by the FDA in the United States and inclusion in the EU's positive list of UV filters. When formulating with this ingredient, careful consideration must be given to its stability and potential interactions with other sunscreen actives to ensure optimal performance and skin protection.
