| 中文摘要:以5种面膜为研究对象，采用电感耦合等离子体质谱技术，通过外标法对面膜中的12种微量元素进行定量分析，建立了敷面膜时间与微量元素含量的关系曲线，探究面部皮肤对微量元素的吸收率。结果表明：5种面膜中均检出的微量元素含量由高到低为Al、Sn、Fe、Zn、Hg，含量为0.027~5.209 mg/kg；人体面部皮肤对Se、Zn和Fe的吸收率较高，对Sn、Al的吸收率较低。该定量方法简单、快速、准确可靠，可为面膜中微量元素的研究及面膜的安全有效使用提供实验依据。 |

| Abstract:With five kinds of facial mask as the research object,12 elements in facial masks were quantitatively analyzed by inductively coupled plasma mass spectrometry(ICP-MS) with external standard method.The relationship between mask sufficient time and elements content was established to explore the absorption rate of facial skin for trace elements.The experimental results showed that the contents rank of the elements detected in all five masks were Al,Sn,Fe,Zn and Hg,with a content range of 0.027-5.209 mg/kg.Through the absorptivity experiment,it was found that the human facial skin was more likely to absorb the elements Se,Zn and Fe other than the elements Sn and Al.In addition,the method established in this paper is simple,rapid and accurate,and could provide an experimental basis for study on trace elements in facial masks and their safe and effective uses. |
