高效液相色谱法测定染发剂中对苯二胺等32种染料组分

采用高效液相色谱法对甘肃27个市、州、县地区抽样的50批次染发剂类化妆品进行检验，分析染发类化妆品中使用的染料组分种类、含量情况.试验结果发现对苯二胺、间苯二酚、间氨基苯酚、对氨基苯酚等4种染料组分的使用频率较高.50批染发类化妆品不合格率为50%，其中包括未超规定限量，但产品的批件配方信息与包装标签标识存在问题的染发剂22批次，二批次检出禁用组分，一批次检出苯基甲基吡唑啉酮超规定限量.说明染发类化妆品产品包装标签应进行规范，产品的批件配方信息与包装标签标识的一致性应加强监管.

Determination of p-Benzenediamine etc. 32 Dye Components in Hair Dye by High Performance Liquid Chromatography

The quality of 32 components, such as p-benzenediamine, in hair dye cosmetics were examined, 50 batches of hair dye cosmetics sampled from 27 cities, counties in Gansu province were examined by high performance liquid chromatography(HPLC). Results showed that the frequency of use of 4 components is fairly high in the 50 batches of hair dye cosmetics and the failure rate of the 50 batches of hair dye cosmetics was 50%. Even if the prescribed limit was not exceeded, 22 batches were of problematic samples, in 2 batches banned components were detected, in 1 batch, phenylmethylpyrazolinone exceeded the prescribed limit. The package labeling of hair dye cosmetics should be standardized, and the consistency between the formula information of approval parts and the label logo of packaging should be strengthened.
