摘要:

采用高效液相色谱法、离子色谱-电导检测器法及离子色谱-紫外检测器法对48批特殊烫发类产品中的巯基乙酸含量进行检测,研究了3种检测方法之间的差异及适用性,得到了48批烫发类产品中巯基乙酸的整体添加数据,并对添加趋势进行了分析。结果表明,离子色谱-紫外检测器法可以有效排除杂质干扰,且方法学与现有《化妆品安全技术规范》(2015年版)中巯基乙酸的检测方法无明显差异,建议作为补充方法;特殊烫发类产品中巯基乙酸的含量均符合市场行业制定的添加含量上限标准。

Abstract:

Thioglycolic acid contents in 48 batches of special hair perm products were detected by HPLC, ion chromatography-conductivity detector and ion chromatography-UV detector. The differences and applicability of the three detection methods were studied. The overall adding data of thioglycolic acid in 48 batches of hair perm products was obtained, and the adding trend was analyzed. The results show that the ion chromatography-UV detector method can effectively eliminate the interference of impurities, and it is similar as the detection method of thioglycolic acid in the current “Safety and Technical Standards for Cosmetics”(2015 edition). It is recommended as a supplementary method. The contents of thioglycolic acid in all special hair perm products meet the upper limit standard established by the industry.

Key words: special hair perm products, thioglycolic acid, high performance liquid chromatography, ion chromatography
