Embodiment 1
[0078] This example provides a method for establishing a mass spectrometry database for high-throughput screening of cosmetic safety risks. The establishment of the database is based on ultra-high performance liquid chromatography, Q-TOF high-resolution mass spectrometry, and SCIEX OS and LibraryView systems. The specific steps are as follows :
[0079] S1: Selection and classification of cosmetic safety risk substances
[0080] A. Selection of Cosmetic Safety Risk Substances
[0081] The compounds included in the high-throughput screening mass spectrometry database of cosmetic safety risk substances are selected according to the following principles: ①. Compounds covered by the relevant standards for the detection of prohibited and restricted components in cosmetics, including physical and chemical testing methods in the "Safety and Technical Specifications for Cosmetics", national standards GB / T, import and export industry standard SN / T, light industry standard QB / T and loc...
Embodiment 2
[0132] This example provides an application of the high-throughput screening mass spectrometry database of cosmetic safety risk substances constructed by the embodiment in the detection of cosmetic safety risk substances, and specifically provides a method for qualitative and quantitative detection of safety risk substances in cosmetics. Use the information-dependent scanning IDA (TOF MS-IDA-TOF MS / MS) mode to collect sample data, and use the non-targeted screening mode (Non-targeted screening) for qualitative screening in combination with the established database. The screening database can be divided into categories Select can also select the total database for screening matching.
[0133] The method for qualitative and quantitative detection of safety risk substances in cosmetics specifically includes the following steps:
[0134] (1) Preparation of samples to be tested
[0135] Accurately weigh 0.2g of a cosmetic sample (accurate to 0.0001g), place it in a 15mL centrifuge...
Embodiment 3
[0150] This embodiment provides a method for qualitative detection of cosmetic safety risk substances, the specific steps are as follows:
[0151] Established the current national standard GBT 24800.2-2009 for the determination of 41 glucocorticoids in cosmetics and the UPLC-Q-TOF method for 42 glucocorticoids such as triamcinolone involved in the method issued by the national bureau "Testing method for fluocinolone in facial mask cosmetics" High-resolution mass spectrometry database.
[0152] 1. Collect and organize the basic information of 42 glucocorticoids including triamcinolone
[0153] The Chinese and English names, chemical molecular formulas, CAS numbers, and precise molecular weights of 42 glucocorticoids such as triamcinolone are shown in Table 5. The mol files are downloaded from the chemspider website, and the basic information is entered into the database. At the same time, the precise molecular weight of the compound was automatically calculated based on the mo...
