摘要:

建立了同时检测淋洗类化妆品中7种异噻唑啉酮类防腐剂的高效液相色谱分析方法及液相色谱-串联质谱确证方法。膏霜乳和液体两种不同基质类型的化妆品样品分别经甲醇超声提取,提取液以离心处理后,取上清液经微孔滤膜过滤后测定。经CAPCELL PAK C18 MGIII (4.6 mm×250 mm, 5 μm)色谱柱分离,以甲醇和0.1%磷酸水溶液为流动相梯度洗脱,流速1.0 ml/min,柱温40 ℃。检测波长为275,282,和319 nm。以高效液相色谱法的结果进行定性筛查,并采用标准曲线法定量,以液相色谱-串联质谱法的结果进行确证。 结果表明,7种异噻唑啉酮类防腐剂在0.1~50 mg/L质量浓度范围内线性关系良好,相关系数均≥0.999 9。在低、中、高3种加标浓度水平下,平均加标回收率分别为97.5%~109.9% (膏霜乳)和95.6%~103.6% (液体);相对标准偏差(RSD)小于3.0%,检出限为0.05~0.11 mg/kg。该方法具有简单、快速、准确性好的特点,适用于淋洗类化妆品中7种异噻唑啉酮类防腐剂的含量测定及质谱确证。

Abstract:

An analytical method for the simultaneous determination of seven isothiazolinone preservatives in rinse-off cosmetics by high-performance liquid chromatography (HPLC) and verification by liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was established. The cream and liquid cosmetic samples were ultrasonically extracted with methanol, centrifuged, and the supernatant was filtered through a microporous membrane for determination. The separation was executed on a CAPCELL PAK C18 MGIII column by gradient elution at a flow rate of 1.0 mL/min with methanol and 0.1% (V/V) phosphoric acid aqueous solution as the mobile phases. The column temperature was set at 40 ℃. The wavelengths of detection were 278, 282 and 319 nm. The results of high performance liquid chromatography were used for qualitative screening, the standard curve method was used for quantification, and the results of liquid chromatography tandem mass spectrometry were used for verification. The results show that the linear ranges of the seven isothiazolinone preservatives are 0.1-50 mg/L, and the correlation coefficients are all greater than 0.999 9. The average recoveries are 97.5%-109.9% (for cream) and 95.6%-103.6% (for liquid), and the relative standard deviations (RSD) are bellow 3.0% at low, medium and high spiked levels. The detection limits are 0.05-0.11 mg/kg. The method is simple, rapid and accurate for the simultaneous determination and verification of seven isothiazolinone preservatives in the rinse-off cosmetics.

Key words: rinse-off cosmetics, high performance liquid chromatography, mass spectrometric verification, isothiazolinone preservatives
