　　【化工仪器网政策标准】指画颜料是一种为儿童特别设计的涂料玩具，通过用手或手指蘸取进行绘画使用，主要有液态和半固态粉末状两种形态，前者可直接用手或手指蘸取使用，后者则需与水混合后再使用。因指画颜料中的有毒有害物质可通过皮肤接触、舔食进入儿童体内，对儿童的身心健康造成严重危害，故而世界各国纷纷出台严格的法规和标准对玩具中有毒有害化学物质进行限制。

　　根据《标准化工作导则第1部分：标准的结构和编写规则》的要求以及《标准编制规则第四部分：试验方法标准》、《标准编制规则第五部分：规范标准》中的各项规定，上海出入境检验检疫局机电产品检测技术中心等单位起草了《指画颜料中三氯生和三氯卡班含量的测定高效液相色谱法》和《指画颜料中苦味剂柚皮苷和苯甲酸地那铵含量的测定高效液相色谱法》。目前，两项标准征求意见稿已经编制完成，现正面向社会公开征求意见。

　　其中，《指画颜料中苦味剂柚皮苷和苯甲酸地那铵含量的测定高效液相色谱法》的方法原理是采乙醇作为提取溶剂，经超声提取10min后冷却、离心、取出清夜、残留物再次提取、合并两次提取清液、蒸干，再加入50%甲醇水溶液溶解残留物，在过滤后采用高效液相色谱仪进行并用DAD检测器检测即可。该标准方法对柚皮苷和苯甲酸地那铵的方法定量限均为4 mg/kg，回收率为85%~110%。

　　《指画颜料中三氯生和三氯卡班含量的测定高效液相色谱法》的方法原理是用采甲醇作为提取溶剂，经超声提取10min、冷却、离心、取出清夜、残留物再次提取、合并两次提取清液并过滤后，采用高效液相色谱仪进行以及DAD检测器检测。实验结果显示对于三氯生和三氯卡班的方法定量限分别是50mg/kg和10mg/kg，回收率为85%~110%。

　　两项有关指画颜料的检测标准中规定需要用到的仪器设备包括有高效液相色谱仪、超声波清洗器、离心机、分析天平、微量取液器、膜过滤器等。

　　两项标准的制订均是我国紧密关注国内玩具市场动态以及发达国家和地区的相关法规动态，结合我国国情不断完善相关检测标准，使生产企业依据规范的标准进行设计和生产，以保护我国未成年人合法权益，同时也促进我国玩具产品的顺利出口。
