GB/T 42423-2023
Introduction
The GB/T 42423-2023 is a Chinese national standard that specifies the determination of dichlorobenzyl alcohol and chlorophenyl glycol (commonly known as chlorophenols) in cosmetics using high-performance liquid chromatography (HPLC) method.
Chlorophenols are widely used as preservatives in cosmetic products, but excessive levels of these compounds can be harmful to human health. Therefore, it is crucial to accurately measure the content of dichlorobenzyl alcohol and chlorophenyl glycol in cosmetics to ensure product safety.
The HPLC method described in this standard provides a reliable and efficient means of analysis. It involves the separation of the target compounds using a high-pressure liquid chromatograph, followed by detection using a UV-visible detector. The method offers high sensitivity and specificity, allowing for precise quantification of dichlorobenzyl alcohol and chlorophenyl glycol in cosmetic samples.
Compliance with the GB/T 42423-2023 standard is essential for manufacturers, regulatory authorities, and other stakeholders in the cosmetic industry to ensure the quality and safety of cosmetic products. By using this standard, manufacturers can accurately determine the levels of chlorophenols in their products, enabling them to take necessary measures to maintain compliance with regulatory limits.
In conclusion, the GB/T 42423-2023 standard provides a robust and effective HPLC method for the determination of dichlorobenzyl alcohol and chlorophenyl glycol in cosmetics. Adherence to this standard is crucial for ensuring the safety and quality of cosmetic products.
