聚偏二氯乙烯材料化妆品包装中邻苯二甲酸酯的测定

Determination of Phthalates in Cosmetic Packaging Made of Polyvinylidene Chloride

本文介绍了液相色谱-质谱联用测定化妆品塑料包装材料中邻苯二甲酸酯的方法,从实验样品选取、实验条件准备等方面入手,并在实验过程中不断修正精密度等条件,结果发现,本次研究所选聚偏二氯乙烯(PVDC)化妆品包装材料样品中的邻苯二甲酸酯含量均不存在超标问题,包装符合行业标准,同时液相色谱-质谱联用测定方法具有较高的使用准确率。

This paper introduces a method for the determination of phthalates in plastic packaging materials of cosmetics by liquid chromatocl-mass spectrometry.Starting from the selection of experimental samples and preparation of experimental conditions,the precision and other conditions are constantly modified during the experiment.In this study,the content of phthalates in the packaging materials of polyvinylidene chloride(PVDC)cosmetics samples did not exceed the standard,and the packaging was in line with the industry standard.At the same time,the determination method of liquid chromatoc-mass spectrometry has a high accuracy.
