BENZOPHENONE-4

Description

Benzophenone-4, also known as sulisobenzone, is a widely used ultraviolet (UV) filter in skincare and cosmetic products. This water-soluble organic compound belongs to the benzophenone family and functions primarily as a broad-spectrum sunscreen agent, offering protection against both UVA and UVB radiation. Its chemical structure allows it to absorb and dissipate harmful UV rays, reducing their potential to cause skin damage.

In formulations, benzophenone-4 is typically incorporated at concentrations between 1% and 10%, depending on the desired level of sun protection. It is particularly valued for its stability in aqueous solutions and compatibility with other cosmetic ingredients. This UV filter is often combined with other sunscreen agents to achieve higher SPF ratings and more comprehensive photoprotection.

While effective, benzophenone-4 has been subject to scrutiny due to potential environmental concerns and rare cases of contact dermatitis in sensitive individuals. Regulatory bodies, including the FDA and EU Commission, have approved its use within specified limits. When formulating with benzophenone-4, it's crucial to consider potential interactions with other ingredients and to ensure compliance with regional regulations governing sunscreen products.
