Research on the Detection Method of Hydrogen Peroxide Content in Oxidized Hair Dyes

简述过氧化氢在氧化型染发剂中的作用原理及对产品质量的影响,对氧化型染发剂中过氧化氢含量主要检测方法——化学滴定分析法(高锰酸钾法)、柱前衍生高效液相色谱法、柱后衍生高效液相色谱法、鲁米诺化学发光法及荧光光谱法进行对比分析。结果表明:柱后衍生高效液相色谱法具有较高的自动化、较宽的线性范围、较低的检测限、较稳定的回收率,优于其他三种检测方法,适合大批量快速检测,但此法操作相对复杂、分析成本较高;化学滴定分析法以其具有的操作简单、精密度低、分析成本低等优点,在染发剂中过氧化氢常量分析中仍然占据着重要地位。

Briefly describe the principle of hydrogen peroxide in oxidative hair dyes and its impact on product quality.Compare and analyze the main detection methods for hydrogen peroxide content in oxidative hair dyes,including chemical titration analysis(potassium permanganate method),pre column derivatization high-performance liquid chromatography,post column derivatization high-performance liquid chromatography,luminol chemiluminescence method,and fluorescence spectroscopy.The results show that post column derivatization high-performance liquid chromatography has high automation,wide linear range,low detection limit,and stable recovery rate,which is superior to the other three detection methods.It is suitable for large-scale rapid detection,but this method is relatively complex in operation and has high analysis cost;The chemical titration analysis method still occupies an important position in the analysis of hydrogen peroxide constant in hair dyes due to its advantages of simple operation,low precision,and low analysis cost.
