荧光增白剂厂家:教你正承认识荧光剂
Fluorescent brighteners factory: teach you to recognize fluorescence agents.
荧光反响及荧光增白剂
Fluorescence response and fluorescent whitening agent
要了解荧光剂要先了解荧光反响,荧光反响就是物质承受紫外线不见光的照耀后会被激化,之后会把被激化的能量转换成肉眼可见的光释出。
To understand fluorescent agents, we need to understand the fluorescent response, which means that the substance will be stimulated when exposed to the invisible ultraviolet light, and then the energy will be converted into visible light.
荧光反响在天然界也适当常见,像是有些食物、药物、叶绿素、细菌乃至霉菌在紫外灯照耀下会发生荧光反响,这称为天然荧光(Natural fluorescence),这是物质固有的特性而且是无害的。
Fluorescence response is also appropriate and common in nature, such as some foods, drugs, chlorophyll, bacteria and even fungi will have fluorescence response under ultraviolet light, which is called natural fluorescence, which is inherent characteristics of substances and harmless.
荧光物质经由紫外线照耀后会放出蓝光,蓝光跟黄光是成互补色,所以会让本来偏黄的衣服或纸张纤维出现皎白、亮彩及艳丽的观感,而这些物质就是现在媒体上所指的荧光增白剂,所以在荧光灯下会出现荧光反响的物质并非都是荧光增白剂,其实许多天然成分都会有荧光反响,这点大家一定要了解。
Fluorescent substances emit blue light when irradiated by ultraviolet rays. Blue light and yellow light are complementary colors, so they can make the original yellow clothes or paper fibers appear white, bright and gorgeous. These substances are the fluorescent whitening agents in the media nowadays, so not all of them will have fluorescent response under the fluorescent lamp. Fluorescent brighteners, in fact, many natural ingredients will have a fluorescence response, which we must understand.
荧光增白剂的相关标准
Related standards of fluorescent whitening agents
现在按照国家标准仅对“可迁移性荧光物质”有所标准。其检测办法一步就是先把测验品置于波长365 mm的紫外灯下检测是否有荧光反响;如有发生荧光反响则再以无荧光反响之纱布进行染色法以承认是否有荧光迁移性。
According to the national standard, there is only a standard for "migratory fluorescent substances". The first step is to put the test under a 365 mm ultraviolet lamp to detect whether there is a fluorescent response; if there is a fluorescent response, then dye it with a non-fluorescent gauze to recognize whether there is a fluorescent migration.

而有可迁移性荧光物质的含义就是指所增加的荧光物质会藉由洗刷、啃咬、流汗或是碰触而转移到人体皮肤或黏膜,依现在规则日常日子品中是不行检出有可迁移性的荧光物质。
The meaning of migrable fluorescent substances is that the added fluorescent substances will be transferred to human skin or mucosa by washing, biting, sweating or touching. According to the current rules, migrable fluorescent substances can not be detected in daily products.
荧光增白剂在动物毒性测验中,并无清晰显示会形成急性损伤或是长时间致癌性,而这类成份关于皮肤的影响或过敏性也是适当低的,所以现在国际各先进国家尚无将荧光剂纳入强制性办理的规则。
In animal toxicity tests, fluorescent whitening agents do not clearly show acute injury or carcinogenicity for a long time, and the effect or allergy of these components on skin is appropriately low, so there is no compulsory regulation for fluorescent agents in advanced countries.
而现在许多人所认知荧光剂关于人体的致病变性,其实是跟漂白剂或者是跟其它结构类似的毒性化学物质搞混了;而许多人所说到的荧光剂关于皮肤的影响或过敏性反响,则可能是跟产品内一起所含的香料或防腐剂(或甲醛)所形成的反响搞混了。
Many people now know that the pathogenic denaturation of fluorescent agents is actually confused with bleaching agents or toxic chemicals similar to other structures, while the skin effects or allergic reactions of fluorescent agents mentioned by many people may be caused by spices or preservatives (or formaldehyde) contained in products. The reaction was mixed up.
荧光增白剂是归于组成的化学物质,而这类物质的意图仅仅让视觉效果变好让产品更有卖相或更讨喜,所以假如能够不增加当然是比较好这样更能够下降顾客使用时的疑虑。但依现在标准来说只要没有检测出“可迁移性荧光物质”,关于物品所发生的荧光反响是不需要有过度惊惧的情绪。
Fluorescent whitening agents are chemicals attributed to composition, and the intent of such substances is only to improve the visual effect and make the product more attractive or pleasant, so if it can not be increased, of course, it is better to be able to reduce customers'doubts when using them. But according to current standards, as long as "migrable fluorescent substances" are not detected, there is no need for excessive fear about the fluorescent response of the object.
