市售含植物提取物面膜中防腐剂成分使用分析

Analysis of preservatives in commercial facial masks containing plant extracts

为对市售含植物提取物的贴片式面膜类产品中的防腐剂添加情况及成分标识情况进行分析,依据《化妆品安全技术规范》2015版,对44批次面膜中甲基异噻唑啉酮等23种防腐剂成分进行含量测定,并对其中防腐剂的种类、含量以及标签比对结果进行分析。检测结果表明,在44批面膜中,检出防腐剂种类主要为苯氧乙醇(70.5%)及尼泊金酯类防腐剂(68.2%),标签比对结果表明,仅12批的备案标签标识和实际检出情况相符,不相符的情况以检出标签外的尼泊金酯类防腐剂为主。另有1批检出甲基异噻唑啉酮与甲基氯异噻唑啉酮,两者含量比例为7︰1,不符合《化妆品安全技术规范》要求。

The use of preservatives and the authenticity of label claims for commercial facial masks containing plant extracts were investigated.23 kinds of preservatives were tested in accordance with the Safety and Technical Standards for Cosmetics(2015).The testing results showed that,among the 44 batches of masks,the preservatives mostly detected were phenoxyethanol(70.5%)and nipagin ester preservatives(68.2%).The comparison results of labels showed that there were only 12 batches whose filed labels were consistent with the actual detection results,and the inconsistency was mostly the detection of nipagin ester preservatives that were not included in the label.In addition,1 batch was considered unqualified due to the detection of methylisothiazolinone and methylchloroisothiazolinone at a content ratio of 7∶1.
