Abstract
Description
technical field
[0001] The present invention relates to a screening method for chemical substances, in particular to a screening method for chemical risk substances of antifungal drugs in toiletries based on ultra-high pressure liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry screening 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,...
