  洗衣液等洗濯用品经常被传出含有荧光增白剂的问题,以至有传言说“荧光剂会致癌”,给消费者形成了不小的恐慌。这些传言是真的吗?荧光增白剂到底平安不平安?
  Laundry detergents such as laundry fluids are often reported to contain fluorescent whitening agents, so there are rumors that "fluorescent agents can cause cancer", which has caused considerable panic to consumers. Are these rumors true? Is the fluorescent whitening agent safe or not?
  什么是荧光?
  What is fluorescence?
  其实,荧光只是一种冷发光的物理现象,是吸收一定波长的入射光(通常是紫外线或X射线)后发出更长波长的出射光(通常为可见光)。而一旦中止入射光,发光现象也会随之消逝。据专家引见,荧光物质普遍存在于自然界中,也存在于各种动物体内,像很多海洋生物如虾、蟹、水母,以及陆地上的萤火虫等,它们能发光正是由于体内含有各种荧光蛋白质。一些荧光物质以至在人的身体中也存在,比方局部氨基酸,维生素A、E和B12,核苷酸,荷尔蒙等。许多常见的食品也都有荧光,比方酱油、普洱茶、白酒、红茶和咖啡等发酵食品,都能够产生荧光。
  In fact, fluorescence is only a physical phenomenon of cold luminescence. It absorbs a certain wavelength of incident light (usually ultraviolet or X-ray) and emits a longer wavelength of emitted light (usually visible light). Once the incident light is stopped, the phenomenon of luminescence will disappear. According to experts, fluorescent substances are ubiquitous in nature, but also in various animals, such as many marine organisms such as shrimp, crab, jellyfish, and land fireflies, which can emit light precisely because of the fluorescent proteins in the body. Some fluorescent substances also exist in human body, such as local amino acids, vitamins A, E and B12, nucleotides, hormones and so on. Many common foods also have fluorescence, such as soy sauce, Pu'er tea, liquor, black tea and coffee fermented foods, can produce fluorescence.
  消费者常常对能发出荧光的物质有一种恐惧感,以为会对人体有伤害。而国度染料质量监视检验中心高级工程师董仲生指出,一种物质会不会发出荧光,与能否有毒性毫不相关,由于荧光现象是一种地道的物理现象,没有化学反响,不会对安康产生不良影响。况且能发出荧光的维生素、蛋白质、色氨酸、酪氨酸以及荷尔蒙等,还是维持生命所必需的物质,能被人体所吸收。所以说,毒性和荧光之间不存在任何关系。
  Consumers often have a fear of substances that emit fluorescence, thinking they will harm the human body. Dong Zhongsheng, senior engineer of the National Dye Quality Monitoring and Inspection Center, pointed out that whether a substance emits fluorescence or not has nothing to do with whether it is toxic or not. Because fluorescence is a genuine physical phenomenon, there is no chemical reaction, it will not have adverse effects on health. Moreover, the fluorescent vitamins, proteins, tryptophan, tyrosine and hormones are also essential for life maintenance and can be absorbed by the human body. So there is no relationship between toxicity and fluorescence.

  很多白色织物自身在制造过程中都会添加荧光增白剂,在KTV、演唱会等有绚丽的灯光下看到荧光反响就是实例。另外,实践上我们身边很多白色东西都是含有荧光增白剂的。比方塑料管、复印纸等。所谓荧光增白剂,就是一类能吸收紫外光,从而发出蓝光或蓝紫光的有机化合物。
  Many white fabrics will add fluorescent whitening agent in their manufacturing process, and the fluorescent response in the brilliant lights of KTV, concerts and so on is an example. In addition, in practice, many white things around us contain fluorescent whitening agents. For example, plastic pipe, copy paper, etc. The so-called fluorescent whitening agent is a kind of organic compound which can absorb ultraviolet light and emit blue or blue-violet light.
  据理解,荧光增白剂曾经有超越75年的运用历史。据中国洗濯用品工业协会相关人士引见,荧光增白剂是一种功用性助剂,许多衣物在衣着运用过程中,由于各种缘由招致泛黄,白色衣物白度降落,颜色不再鲜艳。在洗濯剂中参加荧光增白剂,可让衣物尽量恢恢复来的白度和颜色。因而,国内外衣物洗濯剂中都普遍添加荧光增白剂。
  It is understood that fluorescent brighteners have been used for more than 75 years. According to the relevant personages of China Washing Products Industry Association, fluorescent whitening agent is a functional additive. Many clothes in the use process, due to various reasons, cause yellowing, white clothes whiteness fall, color is no longer bright. The addition of fluorescent whitening agent in the detergent can restore the whiteness and color of the clothes as much as possible. Therefore, fluorescent whitening agents are commonly added in laundry detergents at home and abroad.
  荧光增白剂平安吗?
  Is the fluorescent whitening agent safe?
  我们每个人都贴身接触过织物里的荧光增白剂,也运用过洗衣液等含有荧光增白剂的洗濯产品。据理解,荧光增白剂从上个世纪开端,由最初的主要用于纺织品,开展到如今主要用于洗濯用品等多个行业,至今还没有呈现过因荧光剂形成致病或人身伤害的案例。
  Each of us has personal contact with fluorescent whitening agents in fabrics, and also used laundry detergents and other products containing fluorescent whitening agents. It is understood that fluorescent whitening agents have been mainly used in textiles since the beginning of the last century, and now they are mainly used in washing products and other industries. So far, there have been no cases of illness or personal injury caused by fluorescent agents.
  从上世纪五、六十年代开端,盘绕着荧光增白剂的平安性,国外就开端停止研讨,多国毒理学家及欧洲化学工业协会、欧洲肥皂洗濯剂协会、日本国立卫生实验机构、日本肥皂洗濯剂协会等独立组织、研讨机构停止了全面深化的研讨并发布了报告。研讨结果标明,荧光增白剂没有皮肤致敏性、光毒性、经口毒性、经皮毒性、生殖毒性、致突变性和致癌性。早在2011年8月,中国洗濯用品工业协会在北京召开“洗濯剂用荧光增白剂平安性专家媒体见面会”,有关权威专家也给出结论:“含荧光增白剂的衣料洗濯剂对人体和环境是平安的。”
  Since the 1950s and 1960s, around the safety of fluorescent whitening agents, foreign countries began to stop discussing. Independent organizations and research institutions such as multinational toxicologists and European Chemical Industry Association, European Soap Washing Agent Association, Japan National Health Laboratory Agency, Japan Soap Washing Agent Association and so on have stopped all-round and in-depth discussing and published reports. The results show that fluorescent whitening agents have no skin sensitization, phototoxicity, oral toxicity, percutaneous toxicity, reproductive toxicity, mutagenicity and carcinogenicity. As early as August 2011, the China Association of Washing Products Industry held an "expert media meeting on the safety of fluorescent brighteners for washing agents" in Beijing. Authoritative experts also concluded that "laundry detergents containing fluorescent brighteners are safe for human beings and the environment."
