| titleOfInvention | Method for measuring content of 3-benzylidene camphor in cosmetics |
| abstract | The method discloses a method for measuring the content of 3-benzylidene camphor in cosmetics, belongs to the field of analysis and detection, and particularly discloses a method for measuring the content of 3-benzylidene camphor in cosmetics by gas chromatography-mass spectrometry, which comprises the following steps: purifying the sample, extracting the sample, and qualitatively determining the sample and calculating the detection result. Dissolving a sample by using a mixed solution of acetonitrile and water, purifying and removing impurities by using an SPE (solid phase extraction) column, collecting effluent liquid, adding excessive sodium chloride solid to saturate the effluent liquid, extracting a target substance in the sample by using a reverse phase extraction mode, concentrating an extracting solution, fixing the volume, performing mechanical analysis, and quantifying by using an external standard method. The method is suitable for measuring the content of the 3-benzylidene camphor in the cosmetics, and has the advantages of simplicity, rapidness, accurate qualitative and quantitative determination, high recovery rate and the like. |
