　　【化工仪器网政策标准】壬二酸，俗名杜鹃花酸，是一种外观为白色至微黄色单斜棱晶、针状结晶或粉末状物质。一般壬二酸被用作增塑剂，并用于醇酸树脂、漆和化工合成。但是，壬二酸对人体皮肤、眼睛、粘膜和上呼吸道有刺激作用，吸入或摄入都会对身体造成伤害。同时，壬二酸对环境也有危害，可以对水体和大气造成污染。

　　截止到目前，国内外用于检测壬二酸的方法包括三氟化硼-乙醚衍生气相色谱法、容量分析法、硫酸甲醇衍生气相色谱-质谱联用分析及将壬二酸衍生为对溴苯乙酮二酯，采用高效液相色谱法检测几种方法。

　　考虑到壬二酸熔点为 98～103℃，沸点为 286℃，不易气化，用容量分析法测定时的干扰比较大，不能精确测定化妆品中的壬二酸含量，而采用衍生的方法，将壬二酸转化给酯类，通过色谱柱进行分离，火焰离子化检测器检测，不仅灵敏度高，分离度也好。故我国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。

　　根据国家标准化管理委员会关于下达的2019 年第一批国家标准制修订计划的通知(国标委发〔2019〕11 号)要求，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承担了《化妆品中壬二酸的检测气相色谱法》国家标准的制定工作。在编制过程中，研究组查阅了国内外有关文献资料，参考了各行业部门制定的同类标准方法，遵循“先进性、实用性、统一性、规范性”的原则，注重标准的可操作性，于2020 年 6 月形成征求意见稿并上报全国检标委。目前该标准正在面向社会公开征集意见。

　　该标准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。在检测过程中，除了会用到气相色谱仪外，分析天平、离心机、涡旋振荡器、氮吹仪。

　　俗话说，爱美之心人人有之，化妆品作为一种能让我们变美的物质，其受众极为广泛。建立化妆品中壬二酸检测方法，能有力保障化妆品质量，为“爱美人士”提供合格的化妆品。
