Introduction

The tested substances in this document are prohibited substances stipulated in my country's "Cosmetics Safety Technical Specifications". Prohibited substances refer to substances that cannot be added to cosmetics as raw materials or components in cosmetics production. "Cosmetics Safety Technical Specifications" regulations Determination. If it is technically unavoidable to bring prohibited substances into cosmetics as impurities, a safety risk assessment should be carried out to ensure that they are normal, reasonable and available. It shall not cause harm to human health under the foreseeable use conditions. At present, my country has not yet stipulated the limit value of these substances. This document only provides detection methods for the determination of these substances in cosmetics. Eleven glucocorticoids such as dessononide in cosmetics Determination of liquid chromatography/tandem mass spectrometry
