Description

General description

Camphor benzalkonium methosulfate (CBM) is a highly photostable, fat-soluble organic ultraviolet (UV) filter approved for use in sunscreens/cosmetics to absorb UV rays. CBM is one of the most effective UV absorbers which offers protection against UVB radiations.

Application

Camphor benzalkonium methosulfate may be used as a reference material for the determination of the analyte in sunscreen products by liquid-chromatographic method.
