教你如何区分化装品中能否含有荧光剂
Teach you how to distinguish whether cosmetics contain fluorescent agents or not
1.荧光与荧光剂
1. Fluorescence and Fluorescent Agents
荧光是指处于基态的物质在承受某种射线照射后,携带能量添加而发作轨道跃迁,当中止照射后,电子回到原轨道的同时,以光的方式释放出这局部能量,这种光就叫作荧光;呈现这种景象的进程叫作荧光激起。这一原理普遍用于照明工业和迷信研讨。有许多物质自然的或许人工的都可以在紫外光照射时收回荧光。激起波长不同、或许物质不同,所收回的荧光颜色不同。应用这个原理,人类特意开收回一些可以发生UVF的物质,用于不同的用处,那麼这些特意制造出来的、用于发生荧光的物质,就叫作荧光剂。换句话说,自然可以收回荧光的物质不在此列,其目的和用处不是用于发生荧光的物质,也不属于荧光剂。在多种多样的荧光剂中,有一大类用于增白,它次要在紫外光照射下收回蓝白色的荧光,叫作荧光增白剂,其收回的荧光强度非常之高,因此特别可以惹起关注。总结起来就是:能发生荧光的,不一定是荧光增白剂。
Fluorescence refers to the orbital transition of a substance in the ground state when it is irradiated by a certain kind of radiation. When the irradiation is stopped, the electron returns to its original orbit and releases the local energy in the form of light, which is called fluorescence. The process of presenting this phenomenon is called fluorescence excitation. This principle is widely used in lighting industry and superstition research. Many substances can recover fluorescence naturally or artificially when exposed to ultraviolet light. The color of fluorescence recovered varies depending on the wavelength of excitation or the substance. Applying this principle, humans deliberately retrieve some substances that can produce UVF for different purposes, so these specially manufactured substances for fluorescence are called fluorescent agents. In other words, the substances that naturally recover fluorescence are not included. Their purpose and use are not substances used to produce fluorescence, nor are they fluorescent agents. Among various fluorescent agents, there is a large category for whitening. It takes back the blue-white fluorescence under ultraviolet light. It is called fluorescent whitening agent. Its recovery fluorescence intensity is very high, so it can attract special attention. To sum up, it is not necessarily a fluorescent whitening agent that can produce fluorescence.

2。荧光剂的平安性
2. Safety of fluorescent agents
以前已经写过:荧光剂有很多种,平安性不能混为一谈,有时分让人觉得很迷惑。有的荧光剂已确定非常无害,例如多氯联苯类,化学性质相当波动,进人人体后易被吸收,并积存起来,很难排出体外。
It has been written before: there are many kinds of fluorescent agents, safety can not be confused, sometimes people feel very confused. Some fluorescent agents have been identified as very harmless, such as polychlorinated biphenyls, whose chemical properties fluctuate considerably and are easily absorbed and accumulated in human body, making it difficult to excrete them from the body.
植物毒性实验标明它具有致畸变、致癌的作用。假如人体内多氯联苯的贮存量达N(o.5-2)g时就会惹起中毒。食品及接触食品的包装纸,制止添加荧光剂(大家应该还记得去年康徒弟面碗被曝有荧光剂的事情,后来我经过实验证明康徒弟面碗只是在碗外层不接触食物的印刷局部运用了含荧光剂的涂布纸,因而这样做并不违规。
Phytotoxicity experiments indicated that it had teratogenic and carcinogenic effects. If the amount of PCBs stored in human body reaches N (o.5-2) g, it will cause poisoning. Food and food wrapping paper, stop adding fluorescent agent (you should remember last year when the Kangdu noodle bowl was exposed to fluorescent agent, then I experimented to prove that the Kangdu noodle bowl only used fluorescent coating paper on the printing part of the outside of the bowl which did not touch food, so it was not against the rules.
3.哪些中央的荧光剂需求留心你晓得吗
3. Do you know which central fluorescent agents need attention?
看样子我们暂时还不能有一个一致的结论,那我们权且以为荧光剂是平安的。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。由于它们曾经被固化在相应的物体外面,洗不掉,也不会转移到皮肤,更不要说被消化道吸收。这也是各种工业规范答应运用的。我们不需求爲这些外面的荧光剂担忧,所以不要风声鹤唳。成绩来了:既然如此,我们反省、识别荧光剂还有什麼意义呢?假设在任何中央荧光剂都是平安有害的,甚至是有益处的,在化装品、卫生巾、纸巾上识别出荧光增白剂也是有价值的。首先,就化装品来说,添加了荧光增白剂,比较比较少该当列在成分表上。很惋惜,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,你基本找不到荧光剂的影子。作爲消费者,可以选择有荧光剂的产品,但好歹也要被知会一声,更不要法规有这个要求了。
It seems that we can't reach a consistent conclusion for the time being, so we have the right to think that the fluorescent agent is 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 outside the corresponding objects, they can not be washed out, nor can they be transferred to the skin, let alone absorbed by the digestive tract. This is also the promise of various industrial norms. We don't need to worry about these outside fluorescent agents, so don't whisper. Achievements: In this case, what is the significance of our reflection and identification of fluorescent agents? Assuming that any central fluorescent agent is safe, harmful or even beneficial, it is also valuable to identify fluorescent whitening agents on cosmetics, sanitary napkins and paper towels. First, as far as cosmetics are concerned, fluorescent whitening agents should be added, at least on the composition list. Unfortunately, at present, we have tested facial mask and cream with fluorescent agents. No one has done this. You can hardly find the shadow of fluorescent agent. As consumers, they can choose products with fluorescent agents, but they should also be informed, not to mention the requirement of laws and regulations.
