欧盟委员会决定撤销杀菌剂氯化双癸基二甲基铵(DDAC)的登记。根据之前适用的欧盟杀生剂产品指令98/8/EC,DDAC曾被批准用于木材防腐。欧盟要求其成员国确保在2013年6月20日之前撤销DDAC的登记,并给予一年的宽限期消耗存货。氯化双癸基二甲基铵是一种毛织品的防蛀剂,能控制昆虫病害,在医药卫生和民用等方面用作消毒剂和杀菌剂。DDAC是季铵盐杀菌剂的第三代产品之一,其对微生物的杀灭能力明显高于第一、二代产品。
The European Commission has decided to revoke the registration of the biocide chlorododecamethyldimethylammonium (DDAC). DDAC was approved for wood preservation under the previously applicable EU Biocide Product Directive 98/8 / EC. The EU requires its member states to ensure that DDAC registrations are withdrawn by June 20, 2013, and that a one-year grace period be used to stock up. Didecyldimethylammonium chloride is a wool fabric moth-proofing agent that can control insect diseases and is used as a disinfectant and bactericide in medical, hygiene and civil applications. DDAC is one of the third generation products of quaternary ammonium bactericide. Its ability to kill microorganisms is obviously higher than that of the first and second generation products.
