　　【化工仪器网政策标准】爱美是人之天性，在这一过程中，化妆品可以达到清洁、保养、美容、修饰和改变外观的作用，甚至是修正人体气味、保持良好状态，而这也使得化妆品成为很多人的生活必需品。为此，保障化妆品质量安全势在必行，而我国也早已出台了诸多政策法规，包括有：《化妆品检验规则》、《化妆品通用检验方法折光指数的测定》、《化妆品通用检验方法颗粒度(细度)的测定》、《化妆品中帕地马酯的测定高效液相色谱法》等。

　　为了进一步保障化妆品的质量安全问题，我国生产研发了诸多仪器设备以检测产品质量，与此同时，各类政策标准也不断出台。近期，一项由上海市质量监督检验技术研究院、中检华纳质量技术中心等共同起草的《化妆品中壬二酸的检测气相色谱法》正面向社会征求意见。而该标准引用了GB/T 6682《分析实验室用水规格和试验方法》，规定了化妆品中壬二酸的检测气相色谱测定方法，适用于水剂、膏霜、乳液和面膜类化妆品。

　　因容量分析法测定化妆品中壬二酸含量时干扰较大，检测结果不一定准确，故而《化妆品中壬二酸的检测气相色谱法》的起草组在经过多方试验，拟建立通用性及操作性强、快速简便的前处理方法，利用气相色谱法准确测定化妆品中的壬二酸。

　　阅读标准征求意见稿后可知，《化妆品中壬二酸的检测气相色谱法》中所规定的检测方法原理是试样在浓硫酸和乙醇条件下衍生，用正己烷萃取，浓缩后经气相色谱分离，再使用氢火焰离子化检测器检测，之后根据保留时间定性，外标法定量即可。标准中也显示本方法的检出限为15mg/kg，定量限为50mg/kg。而实验需要用到的仪器设备包括有配备氢火焰离子化检测器的气相色谱仪、分析天平、离心机、涡旋振荡器、刻度管、氮吹仪等。

　　需要注意的是，在同一实验室，由同一操作者使用相同设备，按相同的测试方法并在短时间内对同一被测对象相互独立进行测定获得的两次独立测试结果的差值不能大于两个测定值的算术平均值的10%。

　　本方法通过实验确定标准的适用范围、定量限等，通过相应的标准化研究对方法学指标进行验证，具有一定的可行性。也相信随着标准的正式实施，其能为化妆品中的壬二酸检测提供标准依据，继而更好地规范壬二酸在化妆品中的使用。
