| titleOfInvention | Method for determining urocanic acid and ethyl ester thereof in cosmetics |
| abstract | The invention discloses a method for determining urocanic acid and ethyl ester thereof in cosmetics. The method comprises the following steps: (1) pre-treating a sample: pre-treating a cosmetics sample, thereby acquiring a filtrate; (2) adopting a high performance liquid chromatography for determining the acquired filtrate; and (3) drawing a standard curve and calculating the content of the urocanic acid and ethyl ester thereof in the sample. According to the method for determining the urocanic acid and ethyl ester thereof in the cosmetics provided by the invention, the high performance liquid chromatography is used for determining the urocanic acid and ethyl ester thereof; a high performance liquid chromatography-mass spectrum or mass-spectrography is used for confirming a positive sample which is determined according to the high performance liquid chromatography; the method is accurate, quick and high in sensitivity; the limit of detection, recovery rate and accuracy all meet the requirements; and the method has an important significance in safety monitoring for the cosmetics. |
