Verwenden
Oxybenzone is an organic compound used in sunscreens. Oxybenzone is used as an ingredient in sunscreen and other cosmetics because it absorbs UVB and short-wave UVA (ultraviolet) rays. Oxybenzone was one of the first compounds incorporated into sunscreen formulations to offer enhanced UVA protection because its absorption spectrum extends to less than 350 nm.
Verwenden
oxybenzone (benzophenone-3) is the drug name for an FDAapproved uV filter and absorber.
Verwenden
Ultraviolet light absorber and stabilizer, especially in plastics and paints.
Verwenden
Sunscreen. UV stabilizer
Verwenden
benzophenone-3 (oxybenzone) is an oil-soluble uV absorber and filter with absorption rates within the uVA and uVB peak ranges. It has an approved usage level of up to 6 percent in the united States and 10 percent in the european union. Benzophenone-3 enhances SPF and is popular among sunscreen formulators given a concern over potential safety problems associated with more traditional sunscreen chemicals. However, some reports associate it with causing photocontact allergy. It is considered a non-comedogenic raw material.
Verwenden
ultraviolet screen
synthetische
Preparation by partial methylation of 2,4- dihydroxy-benzophenone,
? with methyl iodide in the presence of sodium hydroxide;
? with a methyl halide;
? with dimethyl sulfate in the presence of sodium hydroxide or alkaline solution.
Definition
ChEBI: A hydroxybenzophenone that is benzophenone which is substituted at the 2- and 4-positions of one of the benzene rings by hydroxy and methoxy groups respectively.

Allgemeine Beschreibung
White to off-white or light yellow powder.
Air & Water Reaktionen
Insoluble in water.
Brandgefahr
Flash point data for Oxybenzone are not available; however, Oxybenzone is probably combustible.
Flammability and Explosibility
Non flammable
Kontakt-Allergie
BZP-3 is used as a direct sunscreen agent and in antiaging creams. Allergic reactions have been reported. Cross-reactivity is expected in an average of one in four patients photoallergic to ketoprofen.
Sicherheitsprofil
Poison by intraperitoneal route. Mddly toxic by ingestion. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.
