荧光增白剂在织物洗濯剂中的使用
Application of Fluorescent Whitening Agent in Fabric Washing Agent
织物洗濯剂是居民日常生活必需品。随着生死水平的进步,人们对洗濯剂的需求也在不时进步,并朝着环保、方便、经济、的方向开展。
Fabric detergent is a daily necessities of residents. With the progress of life and death level, people's demand for detergents is also improving from time to time, and developing in the direction of environmental protection, convenience, economy and efficiency.
外表活性剂和助剂是织物洗濯剂的次要成分,对洗濯剂的功能和洗濯衣物干净度的效果起着至关重要的作用。纺织印染厂对出厂的面料上停止荧光增白处置是普遍且通用的技术,但是它还达不到永世性洗濯牢度,即随着人们穿着与洗濯,荧光增白剂会零落,衣物会发旧、甚至泛黄等。在洗濯剂中添加一定量、种类适宜的荧光增白剂,不但能添加被洗濯织物的白度或艳丽度、改善洗濯效果,同时还能改善洗濯剂的外观。目前,世界上荧光增白剂消费量的50%是用于洗濯剂行业。因而可以说,荧光增白剂已成爲织物类洗濯剂配方中不可短少的重要助剂之一。
Surface activators and auxiliaries are the secondary components of fabric detergents, which play an important role in the function of detergents and the cleanliness of washing clothes. It is a common and universal technology for textile printing and dyeing mills to stop the fluorescent whitening treatment on the fabrics discharged from the factory, but it can not reach the eternal washing fastness, that is, as people wear and wash, fluorescent whitening agent will be scattered, clothing will be old, even yellowing. Adding a certain amount of fluorescent whitening agent to the detergent can not only improve the whiteness or brightness of the washed fabric, but also improve the appearance of the detergent. At present, 50% of the world's consumption of fluorescent brighteners is used in the detergent industry. Therefore, it can be said that fluorescent whitening agent has become one of the indispensable important additives in fabric detergent formulation.
到比较重要的了,那麼它能否无害呢?
Most importantly, can it be harmless?
研讨人员从各个角度剖析了各种荧光增白剂能够的毒性,包括多大剂量会发生急性毒性;对皮肤和粘膜能否有安慰性;临时接触后致癌、致畸、致渐变的能够性;能否能够惹起过敏;会不会在植物体内蓄积......后果是此类物质的急性毒性很小,且摄入后根本完全从体内排出,没有证据显示有安慰性、三致(致癌、致畸、致渐变)效应、过敏性等。
Researchers analyzed the toxicity of various fluorescent whitening agents from various angles, including how much dose of fluorescent whitening agent can cause acute toxicity; whether it can comfort the skin and mucosa; the ability of carcinogenesis, teratogenesis and gradual change after temporary contact; whether it can cause allergies; whether it can accumulate in plants... The consequence is this kind of substance. The acute toxicity is very small, and it is completely discharged from the body after ingestion. There is no evidence that there are comfortable, trigenic (carcinogenic, teratogenic, gradual) effects, allergies and so on.
独一的不良影响是,在注入荧光增白剂同时表露在210-275纳米波长紫外光下,小鼠体内发生了肿瘤,但这种短波紫外光在自然环境中是无法进入大气层的,也就是说这个研讨后果对地球生物没有自创意义。
The only adverse effect is that tumors occur in mice when fluorescent whiteners are injected and exposed to ultraviolet light at 210-275 nanometers, but this short-wave ultraviolet light cannot enter the atmosphere in the natural environment, that is to say, the consequences of this study have no self-creative significance for Earth's organisms.
这样的音讯抵消费者来说应该是个好音讯,但对需求研讨经费的科研人员却没有协助,因此从上世纪八十年代开端,荧光增白剂生物效应的研讨渐少,更多人转而研讨如何进步此类物质的检测程度,剖析它们在环境中的散布与降解,以及怎样分解出更容易降解的、对环境危害更小的荧光增白剂。而国际上也普遍承受了此类物质作爲纸张、塑料制品、纺织品、衣物洗濯剂等的惯例添加物。
This kind of information should be good news for consumers, but it is not helpful for researchers who need research funds. Since the 1980s, there has been little research on the biological effects of fluorescent whiteners. More people have turned to how to improve the detection of such substances and analyze their distribution and distribution in the environment. Degradation, and how to decompose more easily degradable fluorescent whitening agents with less harm to the environment. In the world, such substances are generally accepted as routine additives for paper, plastic products, textiles, laundry detergents and so on.
很难经过皮肤吸收
Difficult to absorb through the skin
当然,即使是如此低的毒性,我国仍规则严禁增白剂添加于与食物接触的各类物质中,包括食品包装用纸,所以实际上说,消费者经过食用摄入荧光增白剂的能够性很小,次要是从皮肤途径摄入。由于皮肤外表掩盖有角质层,能严重障碍真皮层以下各细胞对大分子无机物的吸收才能,因此相比于食用和吸入,大局部物质经过皮肤接触进入人体的难度大得多。更不要说,挂在皮肤上的荧光增白剂随时有被再次洗脱的风险,不能够渐渐等着被吸收。
Of course, even with such low toxicity, whitening agents are strictly prohibited to be added to all kinds of substances in contact with food, including food packaging paper, so in fact, consumers have very little ability to ingest fluorescent whitening agents after eating, mainly from the skin. Because the cuticle is concealed on the surface of the skin, it can seriously hinder the ability of cells below the dermis to absorb macromolecule inorganic substances. Therefore, compared with food and inhalation, it is much more difficult for most substances to enter the human body through skin contact. Not to mention, fluorescent whiteners hanging on the skin are at risk of being washed out again at any time, and cannot be absorbed gradually.
评价一个物质对人体的毒性风险通常要看三个方面:一是该物质本身及其降解产物的毒性大小;二是人群能够接触到这个物质的剂量大小;三是该物质有没有生物蓄积性,会不会随着不时接触而在人体越积越多。
The toxicity risk of a substance to human body usually depends on three aspects: first, the toxicity of the substance itself and its degradation products; second, the dose of the substance that can be touched by the population; third, whether the substance has bioaccumulation and will accumulate more and more in the human body with the occasional exposure.
