摘要:

为了准确高效地检测淋洗类化妆中防腐剂的添加量,建立了一测多评法测定淋洗类化妆品中23种防腐剂含量的高效液相色谱方法。采用50%甲醇水溶液处理淋洗类样品,梯度洗脱,在C18色谱柱上分离检测23种防腐剂,选取4-羟基苯甲酸甲酯为内部参照物,建立其他22种防腐剂的相对保留时间和相对校正因子,计算各组分的含量。分析结果表明,在该实验条件下23种防腐剂各组分在一定质量浓度范围内呈现良好线性关系,相关系数(r2)均大于0.999,检出限(LOD)为0.033~4.0 μg/g,溶液在7天之内保持相对稳定,各组分的RSD结果在1.6%~2.7%。一测多评法与外标法测定结果一致性良好,相对平均偏差在0.21%~4.9%之间,因此该方法可以用于淋洗类化妆品中23种防腐剂的测定和质量控制。

Abstract:

A quantitative analysis of multi-components by single marker (QAMS) method for the determination of 23 preservatives in rinse-off cosmetics was established. Samples were extracted with 50% methanol aqueous solution, and 23 preservatives were separated and detected on a C18 column by high performance liquid chromatography (HPLC) with gradient elution. 4-Hydroxybenzoic acid methyl ester was selected as the internal reference substance. The relative time and the relative correction factors of the other 22 kinds of preservatives were established to calculate the content of each component. The results show that the 22 kinds of preservatives have good linear relationships within a certain mass concentration range, and the correlation coefficients (r2) are all greater than 0.999. The limits of detection (LOD) are in the range of 0.033-4.0 μg/g. The solutions remain relatively stable within 7 days. The results of the relative standard deviation (RSD) of each component are between 1.6% and 2.7%. The quantitative analysis of multi-components by a single-marker (QAMS) method and the external standard method have good consistency in the measurement results, and the relative average deviations are between 0.21% and 4.9%. Therefore, this method can be used for the determination and quality control of 23 preservatives in rinse-off cosmetics.

Key words: rinse-off cosmetics, preservatives, quantitative analysis of multi-components by single marker, high performance liquid chromatography
