荧光增白剂在日常日子中对人体健康有影响吗?
Does fluorescent whitening agent affect human health in everyday life?
日子中咱们都或多或少听过“荧光增白剂”,知道把他加进去东西就会变白,并且人们每逢说到“荧光增白剂”都谈判之色变,鄙夷不屑。那么这篇文章我就尽量用简练易懂的言语,为大家揭开"荧光增白剂”的面纱。
We have all heard of "fluorescent whitening agent" more or less in our daily life. We know that adding fluorescent whitening agent to something will turn white. And when people talk about "fluorescent whitening agent", they are disdained and disdained. Then I will try my best to use concise and easy-to-understand language to unveil the "fluorescent whitening agent" for you.
荧光增白剂并不是白色的,而是一种无色染料,他的增白原理是:吸收阳光中的紫外线,使分子中电子激发,再回到基态时,紫外线能量便消失一部分,转化成能量较低的蓝紫色可见光反射出来。抵消了织物上因反射光中黄光过多而构成的黄色感,与织物上反射出的侧重的黄光混合为白光,织物不只白度增加,并且增加反射率,使得织物的亮度进步,比一般漂白织物愈加顺眼,对淡色织物有增艳作用。
The fluorescent whitening agent is not white, but a colorless dye. Its whitening principle is to absorb ultraviolet rays from sunlight, excite electrons in molecules, and then return to the ground state, the ultraviolet energy disappears, and is reflected by blue-purple visible light with lower energy. It counteracts the Yellow feeling caused by the excessive yellow light reflected from the fabric, and mixes with the yellow light reflected from the fabric to white light. It not only increases the whiteness of the fabric, but also increases the reflectivity, which makes the brightness of the fabric better than that of the ordinary bleached fabric, and has a brightening effect on the light-colored fabric.
1.荧光增白剂VBL:对棉纤维亲和力高,耐光牢度较好,但耐氯牢度较差。(用含氯消毒液很简单使其结构损坏,掉落,衣物色彩泛黄)
1. fluorescent whitening agent VBL: high affinity for cotton fiber, good fastness to light, but poor chlorine fastness. (using chlorine disinfectant is very easy to damage its structure, fall, and the color of the clothes is yellowed).
2.荧光增白剂DT:不溶于水,产品要被制成乳液方式才干染色。(不易水洗掉落)部分荧光增白剂有可能随着衣服洗刷,牢度下降,附着在人体皮肤上。甚至有不法商家,为了进步面膜美白作用,声称贴一次就收效而增加过量荧光增白剂在面膜中。
2. fluorescent whitening agent DT: insoluble in water, products should be dyed by emulsion. (Not easy to wash off) Some fluorescent whitening agents may be attached to human skin as clothes are washed and fastness decreases. There are even illegal businesses, in order to improve the mask whitening effect, claiming that it will be effective once again and increase the excess fluorescent whitening agent in the mask.

荧光增白剂对人体健康影响:
Effects of fluorescent whitening agents on human health:
3.绝大多数荧光增白剂毒性随其化学结构而异大多数荧光增白剂是无毒的或相对无毒的。用于合成洗刷剂的荧光增白剂是无毒或实践无毒的,不会给人类健康构成危险,更不会引发肿瘤(良性,恶性)。个别化合物(前期洗刷剂中常用的吡唑啉类荧光增白剂)会引起过敏现象,但已筛选。
3. The toxicity of most fluorescent whiteners varies with their chemical structure. Most fluorescent whiteners are non-toxic or relatively non-toxic. Fluorescent whitening agents used in synthetic scrubbers are non-toxic or non-toxic in practice. They do not pose a risk to human health, nor do they cause tumors (benign, malignant). Individual compounds (pyrazoline fluorescent whitening agents commonly used in pre-washing agents) can cause allergies, but have been screened.
4.荧光增白可吸附在植物根部而不会透入其根茎,叶,花和果实中,这表明荧光增白剂对农作物有很高的安全性。环境中的荧光增白剂可光分化(降解)和活性污泥吸附降解,加氯化消毒设备也有较好的处理作用,不会对人类和水生物构成健康影响。
4. Fluorescent whitening can be adsorbed on plant roots without penetrating into its rhizomes, leaves, flowers and fruits, which indicates that fluorescent whitening agents are highly safe for crops. Fluorescent brighteners in the environment can be photodegraded and activated sludge adsorbed and degraded, and chlorinated disinfection equipment also has a better treatment effect, which will not affect human and aquatic organisms health.
5.荧光增白剂是经过吸收阳光中紫外线,再宣布蓝紫色可见光与织物外表黄光混合构成白光,而进步白度,亮度,使色泽艳丽。绝大多数荧光增白剂无毒或相对无毒,不用过火惊惧。但我仍然不建议使用含有过量荧光增白剂的面膜,由于每个人体质不同,长期使用大分子荧光增白剂可能会堵塞毛孔,面部过敏。
5. Fluorescent whitening agent is to absorb ultraviolet rays in sunlight, and then announce that blue-purple visible light and yellow light on the surface of the fabric mix to form white light, and improve whiteness and brightness, so as to make the color brilliant. The vast majority of fluorescent whitening agents are nontoxic or relatively non-toxic. But I still do not recommend the use of excess fluorescent whitening agent mask. Because of the different physique of each person, long-term use of macromolecule fluorescent whitening agent may clog pores and face allergy.
