从现有的资料来看，美国、欧盟及我国均未对洗护用品及化妆品中二恶烷的残留量设立硬性指标。
As shown by the existing information, USA, European Union and our country have not set rigid norm for the residual dioxane in shampoo and hair care products as well as cosmetics.
二恶烷经常会在河水、特别是地下水中被检测到，这主要是由于挥发性的卤代碳氢化合物造成的污染。
Dioxane has been frequently detected in river water, especially in ground water polluted by volatile halogenated hydrocarbons.
4 -二恶烷是一个叫做乙氧基化的化学加工过程的副产品，在这个过程中，化妆品原料和环氧乙烷一起进行处理。
4-dioxane is a byproduct of a chemical processing technique called ethoxylation, in which cosmetic ingredients are processed with ethylene oxide.
1992年至1997年，曾有一些化妆品被发现含二恶烷79ppm，但FDA认为这种含量不会危害消费者。
It found between 1992-1997 that the dioxane level of some cosmetics was 79 parts per million and considered it safe for customers.
常见的有可能造成14-二恶烷污染的原料包括聚乙二醇硬脂酸酯、月桂醇聚醚硫酸酯钠盐、聚乙烯和鲸蜡硬脂醇聚醚-20。
Common ingredients likely to be contaminated with 1, 4-dioxane include PEG-100 stearate, sodium laureth sulfate, polyethylene and ceteareth-20.
但我国《化妆品卫生标准》和2007年版《化妆品卫生规范》中明确指出，二恶烷禁止用作生产原料添加至最终产品中。
