BENZOPHENONE-5

Description

Benzophenone-5, also known as Sulisobenzone, is a synthetic organic compound widely used in skincare and cosmetic formulations as an ultraviolet (UV) filter. This water-soluble ingredient belongs to the benzophenone family and is particularly effective in absorbing UVB rays, with some efficacy against UVA rays as well. Its primary function is to protect the skin from harmful sun damage, which can lead to premature aging and increase the risk of skin cancer.

In skincare products, Benzophenone-5 is typically found in concentrations ranging from 0.5% to 5%. It is often combined with other UV filters to provide broad-spectrum protection. This ingredient is stable in various formulations and can enhance the photostability of other sunscreen agents. Benzophenone-5 is approved for use in sunscreens by regulatory bodies in many countries, including the FDA in the United States and the European Commission in the EU.

While generally considered safe, some individuals may experience skin sensitization or allergic reactions. As with any active sunscreen ingredient, it's important to conduct patch tests and monitor for any adverse effects. Recent studies have also investigated its potential environmental impact, particularly on aquatic ecosystems, prompting ongoing research into its long-term effects.
