Benzophenone-1
What is Benzophenone-1?
Benzophenone-1, chemically known as 2,4-dihydroxybenzophenone, is an organic compound belonging to the benzophenone family of aromatic ketones. It serves primarily as a chemical ultraviolet filter in cosmetic formulations, particularly sunscreens, lotions, and hair products. This ingredient functions by absorbing UVB and short UVA radiation through its conjugated aromatic structure, which excites electrons upon photon absorption. The energy dissipates as harmless heat rather than penetrating the skin. Unlike physical blockers, it is colorless and transparent, blending seamlessly into products without leaving a white cast. Typically incorporated at low levels, it enhances photostability in formulations and contributes to broad-spectrum protection when combined with other filters. Its solubility in oils makes it suitable for oil-based emulsions.
