Beschreibung

Allgemeine Beschreibung

Dioxybenzone belongs to the class of organic UV filters, which find wide application in personal care products and food packaging materials. These filters are prevalently employed as active ingredients in sunscreen formulations due to their ability to emit and/or absorb UVA and UVB radiations. Owing to their ubiquitous use and discharge into the environment, they are identified as common environmental pollutants.

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

Anwendung

Dioxybenzone may be used as an analytical standard for the determination of the analyte in animal samples, artificial seawater samples, fresh and saline waters by various chromatographic techniques.
