Application

Oxybenzone has been used as an analytical reference standard for the quantification of the analyte in environmental samples using gas chromatography coupled to mass spectrometry (GC-MS) and ultra-performance liquid chromatography-electrospray-tandem mass spectrometry (UPLC-ES-MS/MS). It may be used as an analytical reference standard for the determination of the analyte in zebrafish using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) and liquid chromatography with diode array detection (LC-DAD).

General description

Oxybenzone (Benzophenone-3), an organic filter, is an active ingredient used in sunscreens to protect against the damage caused by the UV radiation of the sun. It belongs to the class of benzophenones, widely used in personal care products including cosmetics, sunscreens, toothpaste, additives in food commodities, pharmaceuticals, industrial products, etc. BP-3 is reportedly identified as a pollutant in lakes, rivers, raw and treated wastewaters, sewage sludge, effluents from washing activity in households, environmental sediments, etc.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here
