染发类产品中染发剂的检测及结果分析

Determination and results analysis of hair dyes in hair-dyeing cosmetics

目的研究市售染发剂中氧化型染料的使用情况和染发剂的质量安全情况。方法使用《化妆品安全技术规范》(2015年版)中对苯二胺等32种组分的检验方法对2017年50批和2018年56批湖北地区市售染发剂进行测定和配方查阅统计,分析其中染料组分的使用情况和含量,并对部分可疑组分进行质谱确证。结果106批染发剂中共检出23种染料,对苯二胺、间氨基苯酚、间苯二酚3种染料的使用频率最高,几乎均超过70%。106批染发剂中30批染发剂成分检测结果与样品标签标识不一致,其中2批检出禁用物质邻氨基苯酚,1批检出禁用物质间苯二胺。结论违法使用染发剂禁用组分和标签标识不一致的现象较为严重,应加强对染发剂类产品的监管。

Objective To investigate the usage of oxidizing dyes and the safety risk point of hair dyes in hair-dyeing cosmetics.Methods According to Safety and Technical Standards for Cosmetics(2015),106 batches of hair dye products were detected by high performance liquid chromatography;the types,content and usage were also analyzed by comparison with the ingredients and mass spectrometry confirmation.Results 23 kinds of dye substances were detected from 106 batches of hair dye products,and the use frequency of p-phenylenediamine,m-aminophenol and resorcinol were the highest,with frequencies almost above than 70%.The identification components of 30 batches of hair dye products were inconsistent with the actual determination results,besides 2 batches containing o-aminophenol and 1 batch containing m-phenylenediamine,and the others did not exceed the prescribed limit.Conclusion The use of the prohibited substances and the situations of test results inconsistent of identification are relatively serious,and it is necessary to strengthen supervision of hair dye products.
