摘要


為了解市售化妝品中防腐劑的使用情況,本調查收集自2018年1月1日至2019年6月30日委託新北市某檢驗科技有限公司檢測化妝品防腐劑之產品,依據衛生福利部建議之「化粧品中防腐劑之檢驗方法」,以高效液相層析儀(High performance liquid chromatograph, HPLC)檢測其酸類和酯類防腐劑之存在情形,檢驗項目包括:對羥基苯甲酸(p-Hydroxybenzoic acid)、苯甲酸(Benzoic acid)、己二烯酸(Sorbic acid)、去水醋酸(Dehydroacetic acid)、水楊酸(Salicylic acid)、對羥基苯甲酸甲酯(Methyl p-hydroxybenzoate)、對羥基苯甲酸乙酯(Ethyl p-hydroxybenzoate)、對羥基苯甲酸丙酯(Propyl p-hydroxybenzoate)、對羥基苯甲酸異丙酯(Isopropyl p-hydroxybenzoate)、對羥基苯甲酸丁酯(Butyl p-hydroxybenzoate)、對羥基苯甲酸異丁酯(Isobutyl p-hydroxybenzoate)與對羥基苯甲酸第二丁酯(Secbutyl p-hydroxybenzoate)。結果指出對羥基苯甲酸甲酯之檢出率最高(34.4%),其次為對羥基苯甲酸丙酯(21.9%),研究發現化妝品產品之對羥基苯甲酸酯類防腐劑使用率有高於酸類防腐劑之現象,且與過去國內文獻有關化妝品防腐劑使用之趨勢相似。

並列摘要


In this study, we surveyed the use of various kinds of preservatives in cosmetics. This work was commissioned to a Testing and Inspection Company, New Taipei City from January 1, 2018 to June 30, 2019. According to the "Inspection Methods for Preservatives in Cosmetics" recommended by the Ministry of Health and Welfare, the following preservatives were screened by high performance liquid chromatograph (HPLC): p-hydroxybenzoic acid, benzoic acid, sorbic acid, dehydroacetic acid, salicylic acid, methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, propyl p-hydroxybenzoate, isopropyl p-hydroxybenzoate, butyl p-hydroxybenzoate, isobutyl p-hydroxybenzoate and secbutyl p-hydroxybenzoate. Results show that methyl p-hydroxybenzoate (parabens) was most commonly used (34.4%), followed by isopropyl p-hydroxybenzoate (21.9%). In general, parabens were more commonly used than weak acids as preservatives in cosmetics, a phenomenon similar to that of previously reported in the literature.
