Quality Analysis of 105 Batches of Hair Dye Cosmetics on the Market
Objective:To analyze the quality of commercially available hair dye cosmetics.Methods:All batches of products were detected and analyzed according to 32 components such as p-phenylenediamine in Chapter 4 7.2 of'Cosmetic Safety Technical Specifications'(2015 Edition).A high performance liquid chromatography and mass spectrometry verification method for seven hair dye components was established to detect the samples.Mercury,lead,arsenic and cadmium in all batches of products were detected according to 37 elements such as 1.6 lithium.Results:The unqualified rate of sampling inspection was 44.1%in 2022 and 12.7%in 2023.The main problem was inconsistent with the technical requirements specified in the registration data.The high performance liquid chromatography quantitative detection method of 7 components is accurate and fast,and the mass spectrometry verification method is accurate and reliable.Conclusion:The unqualified rate of commercially available hair dye products has a downward trend,but there are still some manufacturers that do not produce according to the registered formula,and supervision still needs to be strengthened.The components covered by detection standard are incomplete,and the new method is feasible and can provide certain technical support for supervision.
