Benzophenone 4

Description:

Benzophenone-4, also known as BP-4 or by its chemical name, 2-Hydroxy-4-methoxybenzophenone, is an organic compound primarily used as a UV filter in sunscreens and cosmetic products. It belongs to the benzophenone family, characterized by its ability to absorb ultraviolet light, thereby protecting skin from harmful UV radiation. This compound is typically a white to pale yellow solid with a moderate solubility in organic solvents and limited solubility in water. Benzophenone-4 is known for its stability under UV exposure, making it effective in preventing photodegradation of formulations. Additionally, it has been studied for its potential endocrine-disrupting effects, leading to regulatory scrutiny in various regions. Its chemical structure features a hydroxyl group and a methoxy group, contributing to its UV-absorbing properties. Overall, Benzophenone-4 is widely utilized in the cosmetic industry, but its safety profile continues to be evaluated in light of ongoing research into its environmental and health impacts.
