Abstract

The invention discloses a method for screening androgen chemical risk substances in toiletries, comprising the following steps: (1) establishing an accurate mass database and a mass spectrum library of a compound to be tested; (2) pretreatment and detection of actual samples: After the pretreatment steps of extraction, centrifugation, purification, filtration and other pretreatment steps, the sample solution obtained is subjected to ultra-high pressure liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry analysis and detection; (3) Step (2) The obtained test results are compared and analyzed with the accurate mass database and mass spectral library established in step (1), to carry out the screening of androgen chemical risk substances. The screening method for the androgen chemical risk substances in the toiletries established by the invention has high accuracy, strong specificity and high sensitivity, and is applicable to daily detection and quality control of the toiletries.

Description

technical field [0001] The invention relates to a screening method for chemical substances, in particular to a screening method for androgen chemical risk substances in toiletries based on ultra-high pressure liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry check method. Background technique [0002] 1. Chemical risk substances in toiletries have potential harmful effects on consumers' personal health. [0003] From the very beginning of its birth, toiletries have provided protection for people's pursuit of a clean, healthy and fashionable life. With the continuous development and progress of society, people's pursuit of a clean, healthy and fashionable lifestyle has also been continuously upgraded, thus driving the development of toiletries. The industry has stepped into the fast lane of development and upgrading. At present, there are a wide variety of products in the cleaning and care products market, and functional, subdiv...
