2-Hydroxy-4-benzophenone-5-sulfonic acid Usage And Synthesis
Chemical Properties white to yellowish powder
Originator Uval,Dome,US,1965
Uses 2-Hydroxy-4-benzophenone-5-sulfonic acid is a commonly used, FDA approved sunscreen chemical with uVA-absorbing properties and an approved usage level of 5 to 10 percent. It protects a formulation from the effects of uV-light exposure.
Uses sulisobenzone is the drug name for benzophenone-4, a sunscreen chemical.
Uses ultraviolet screen
Uses Ultraviolet absorber for leather and textile fibers; in cosmetics and shampoos.
Manufacturing Process 663 g of dichloroethane and 74.6 g 2-hydroxy-4-benzophenone were charged into a 3-neck flask equipped with stirrer, thermometer, reflux condenser and dropping funnel and a heating mantle. The solution was heated to the reflux temperature (85°C to 86°C) and was dehydrated by distilling off 66.5 g 1,2-dichloroethane. While maintaining at reflux, 30 g chlorosulfonic acid was added slowly over a period of about two hours. The rate of addition was regulated by the speed of evolution of the HCl. After all the chlorosulfonic acid was added, the charge was still maintained at reflux for an additional 15 minutes to remove traces of HCl. It was then cooled to 5°C and filtered. The filter cake was washed with 500 g cold 1,2-dichloroethane and dried. 98 g of product were obtained.
Brand name Sungard (Bayer).
Therapeutic Function Sunscreen agent
Contact allergens BZP-4 is widely used in cosmetics, particularly shampoos and hair products. Cross-reactivity is rarely expected in patients photoallergic to ketoprofen.
