Abstract:

In this study, methanol was used as the extraction solvent, and gas chromatography-tandem mass spectrometry (GC-MS) was used to detect and analyze 19 kinds of flavors and fragrances by SLB-5 ms capillary column (30 m×250 μm×0.25 μm) within 35 minutes. The selected ion monitoring mode (SIM) scanning measurement was used for separation, and the external standard method was used for quantification. The 19 flavors and fragrances have a good linear relationship within the corresponding linear range, and the correlation coefficients are all greater than 0.998 0. The experimental data meet the requirements of the relevant laws, regulations and standards. At the same time, on the basis of “Safety and Technical Standards for Cosmetics” (2015 edition), this study has optimized the types of chromatographic columns, mobile phase composition, and sample extraction solvent selection for the determination of 19 flavors and fragrances in cosmetics. Compared with the original method, the stability of the tested substance is better, and the experimental operation is more convenient and efficient. The experimental results show that the research method is fast, simple, reproducible and durable, and the results are accurate and reliable.

Key words: GC-MS, flavors & fragrances, cosmetics
