This document specifies an analytical method, based on liquid-chromatography (LC) with ultraviolet\/visible spectrometry (UV\/Vis) detection for the detection and quantitative determination of 22 organic UV filters in use in the EU framework. This method has been validated for emulsion-based cosmetic products, lip-balms, lotions and waters.<\/p>\n
