荧光增白剂在生活中用的多吗

  荧光增白剂是一种荧光染料,或称为白色染料,也是一种复杂的有机化合物。荧光增白剂的特性是能激发入射光线产生荧光,使所染物质获得类似荧石的闪闪发光的效应,使肉眼看到的物质很白,达到增白的效果。
  Fluorescent whitening agent is a fluorescent dye, or white dye, and also a complex organic compound. The characteristic of fluorescent whitening agent is that it can stimulate the incident light to produce fluorescence, and make the dyed substance obtain the fluorescent effect similar to that of fluorite, so that the substance seen by the naked eye is very white and achieve the whitening effect.
  以前织物等常常由于含有色杂质而呈黄色,过去都采用化学漂白的方法进行脱色,现在采用在制品中添加荧光增白剂的办法,与原有的黄光辐射互为补色成为白光,提高产品在日光下的白度。增白剂已经广泛应用在腈纶纤维纺丝、纺织品、造纸、洗衣粉、肥皂、橡胶、塑料制品、颜料和油漆等方面。一般荧光增白剂分为两类,一类是水溶性的增白剂,另一类为水不溶性增白剂。前类可用于纸张、涂料、洗衣粉、棉织物的增白剂。另一类可用于化纤、塑料等增白。
  Fabrics used to be yellow because of the color impurities. In the past, chemical bleaching was used to decolorize them. Now, fluorescent brighteners are added to the fabrics to complement the original yellow radiation into white light and improve the whiteness of the products under sunlight. Bleaching agent has been widely used in acrylic fiber spinning, textiles, paper making, laundry powder, soap, rubber, plastic products, pigments and paints. Generally, fluorescent whitening agents are divided into two categories, one is water-soluble whitening agents, the other is water-insoluble whitening agents. The former can be used as brighteners for paper, paint, detergent and cotton fabrics. Another kind can be used for whitening chemical fibers, plastics, etc.
  早在2013年,检测发现北京市面上的六种作业本中,有五种含有荧光增白剂。不仅如此,我们的衣服、唇膏、洗衣粉、卫生巾、衣服、塑料饭盒中都含有荧光剂。
  As early as 2013, five of the six workbooks in Beijing were found to contain fluorescent whitening agents. Not only that, our clothes, lipsticks, washing powder, sanitary napkins, clothes, plastic lunch boxes contain fluorescent agents.
  在日常生活中,我们接触荧光增白剂的机会很多。只要不超过一定标准,不会给我们生活带来麻烦。
  In our daily life, we have many opportunities to contact fluorescent whiteners. As long as it does not exceed a certain standard, it will not bring trouble to our life.
  荧光增白剂——了解与检测
  Fluorescent Whitener-Understanding and Detection有的荧光剂已确定十分有害,例如多氯联苯类,化学性质相当稳定,进人人体后易被吸收,并积存起来,很难排出体外。动物毒性试验表明它具有致畸变、致癌的作用。如果人体内多氯联苯的储存量达0.5g~2g时就会引起中毒。
  Some fluorescent agents have been identified as very harmful, such as polychlorinated biphenyls, which are chemically stable and easily absorbed into the human body and accumulated, making it difficult to discharge them from the body. Animal toxicity test showed that it had teratogenic and carcinogenic effects. If the storage of PCBs in human body reaches 0.5g~2g, it will cause poisoning.
  看样子我们暂时还不能有一个统一的结论,那我们姑且认为荧光剂是安全的。尤其是那些不会迁移到人体上的荧光剂,特别指:用于造纸工业、纺织工业的。布料上的、纸上的、墙壁、家具、家用物品、文具等等。因为它们已经被固化在相应的物体里面,洗不掉,也不会转移到皮肤,更不要说被消化道吸收。这也是各种工业标准许可使用的。我们不需要为这些里面的荧光剂担心——所以不要草木皆兵。
  It seems that we can't reach a unified conclusion for the time being, so let's assume that fluorescent agents are safe. Especially those fluorescent agents that do not migrate to human body, especially those used in paper and textile industries. Fabric, paper, walls, furniture, household goods, stationery, etc. Because they have been solidified in the corresponding objects, can not wash out, will not transfer to the skin, let alone be absorbed by the digestive tract. It is also licensed by various industrial standards. We don't need to worry about the fluorescent agents in it - so don't be a vegetable soldier.

  问题来了:既然如此,我们检查、辨认荧光剂还有什么意义呢?
  The question arises: In that case, what's the point of checking and identifying fluorescent agents?
  假如在任何地方荧光剂都是安全无害的,甚至是有好处的,在化妆品、卫生巾、纸巾上辨认出荧光增白剂也是有价值的。
  If fluorescent agents are safe, harmless, and even beneficial everywhere, it is also valuable to identify fluorescent whiteners on cosmetics, sanitary napkins and paper towels.
  首先,就化妆品来说,添加了荧光增白剂,比较起码应当列在成分表上。很可惜,目前我们测试过的有添加过荧光剂的面膜、霜乳,没有一家这样做,你根本找不到荧光剂的影子。作为消费者,可以选择有荧光剂的产品,但好歹也要被知会一声,更别说法规有这个要求了。
  First, as far as cosmetics are concerned, fluorescent whitening agents should be added, at least on the ingredient list. Unfortunately, at present, we have tested facial mask and cream with fluorescent agents. No one has done this. You can't find the shadow of fluorescent agent at all. As consumers, they can choose products with fluorescent agents, but they should also be informed, let alone regulate this requirement.
  很多这类产品,卖得非常贵,而且都说功效如何如何强劲。1200块钱买50ml含荧光剂的身体美白泥,你要是觉得不冤,那确实——辨认荧光剂没有什么意义。
  Many of these products are very expensive, and they all talk about how powerful they are. 1200块钱买50ml含荧光剂的身体美白泥,你要是觉得不冤,那确实——辨认荧光剂没有什么意义。
