质量监管54 2020年11月（上）/ 总第272期现有一种荧光染料称为荧光增白剂（f l u o r e s c e n t brightener），也被叫为白色染料，是一种复杂的有机化合物。

它能激发入射光线从而产生荧光，对于染色的物质可以得到荧石般的闪闪发光的效应，让人肉眼看上去会使物质很白，从视觉上达到增白的效果。

现在市场上荧光增白剂约有多种结构，大概二百多种化合物，一千多种扥商品。

常用荧光增白剂的品种主要产品见表1。

西方国家对荧光增白剂的毒性已经进行了研究，发现多种荧光增白剂对动物具有光毒和光敏的作用，这会导致致癌和肿瘤的形成。

经研究得出，荧光增白剂中还有一些活跃分子，易迁移到角质层或血液里，对人体的免疫力会有大大的影响。

荧光增白剂可能会对皮肤黏膜有刺激作用，可能会出现红肿瘙痒、感染出血和溃烂等症状，严重点会引发变态反应性皮炎或接触性皮炎等疾病[1,2]。

荧光增白剂VBL 主要用于纤维素织物和纸张的增白，浅色纤维素织物增艳，以及拔染印花白地增白等。

还广泛用于肥皂、合成洗涤剂中以增加被洗涤物的白度。

荧光增白剂VBL 的上染性能基本与染料相似，可用食盐、硫酸钠等无机牙膏中荧光增白剂的检测 ■周 佳1,2　汤 娟1,2　富 薇3　丁友超1　钱 凯1　董绍伟1　曹立华1（1.南京海关工业产品检测中心（原江苏出入境检验检疫局工业产品检测中心）；2.南京金检检验有限公司；3.中国合格评定国家认可中心）摘　要：建立了牙膏中荧光增白剂的高效液相色谱（HPLC-FLD）的检测方法。

牙膏样品经无水硫酸钠搅拌后，由甲醇超声提取。

采用Waters XBridge TM -C18（150 mm×4.6 mm×5μm）为色谱柱进行分离，以水为流动相A、甲醇为流动相B，进行梯度洗脱，激发波长是：350 nm、发射波长是：430 nm。

荧光增白剂在短时间内完成色谱分离，检出限（LODs，S/N=3）和定量限（LOQs，S/N=10）分别为0.03～0.65 mg/L 和 0.1～2.0 mg/L，荧光增白剂相关系数（r 2）均不小于0.999。

荧光增白剂检测标准荧光增白剂是一种常见的化学添加剂，被广泛应用于纺织、造纸、洗涤剂等行业，用于增加产品的白度和亮度。

然而，荧光增白剂的使用也存在一定的风险，因此需要建立相应的检测标准，以确保产品质量和安全性。

一、荧光增白剂的基本原理。

荧光增白剂是一类能够吸收紫外光并发射蓝色荧光的化合物，通过这种荧光效应来增加产品的白度和亮度。

其主要作用是在可见光下，荧光增白剂吸收紫外光，然后再以蓝色光的形式发射出来，使产品看起来更加白皙和明亮。

二、荧光增白剂的检测方法。

1. 紫外光检测法，利用荧光增白剂在紫外光下发出蓝色荧光的特性，通过紫外灯的照射来观察样品是否含有荧光增白剂。

2. 高效液相色谱法，通过高效液相色谱仪对样品进行分析，确定其中是否含有荧光增白剂，并对其含量进行定量分析。

3. 红外光谱法，利用红外光谱仪对样品进行扫描，通过不同波长下的吸收峰来判断样品中是否存在荧光增白剂。

三、荧光增白剂的检测标准。

1. 含量标准，对不同行业中使用的荧光增白剂，制定相应的含量标准，以确保产品的安全性和稳定性。

2. 检测方法标准，针对不同的荧光增白剂检测方法，建立相应的标准操作程序，确保检测结果的准确性和可靠性。

3. 安全标准，制定荧光增白剂的使用安全标准，包括对其使用量、使用范围等方面的规定，以降低潜在的风险。

四、荧光增白剂检测标准的意义。

1. 保障产品质量，建立荧光增白剂检测标准，可以有效监控产品中荧光增白剂的含量，保障产品的质量和稳定性。

2. 保护消费者权益，严格执行荧光增白剂检测标准，可以有效减少产品中荧光增白剂残留对消费者健康的影响，保护消费者的权益。

3. 促进行业健康发展，建立统一的荧光增白剂检测标准，有利于整个行业的规范化和健康发展，提升行业整体形象和竞争力。

五、结论。

荧光增白剂作为一种常见的化学添加剂，其检测标准的建立对于产品质量、消费者健康和行业发展具有重要意义。

需要不断完善和严格执行相关的检测标准，以确保荧光增白剂的安全使用和产品质量的稳定性。

服装荧光剂标准及危害一、荧光剂介绍荧光增白剂是一种荧光染料，在制造纸、纺织品、洗涤剂和塑料等工业中广泛应用。

它能够吸收波长较短的可见光，发射出波长较长的可见光，从而改善产品的颜色。

荧光增白剂对人体是否有危害取决于其浓度和接触时间。

二、荧光剂的危害过量的荧光增白剂可能对人体造成危害，包括：1.刺激皮肤和眼睛，引起过敏反应。

2.影响中枢神经，导致头痛、头晕、失眠等症状。

3.损害肝脏和肾脏。

4.影响生殖系统，降低生殖能力。

然而，目前尚无足够的科学证据表明荧光增白剂对人类具有致癌性。

三、各国荧光剂标准各个国家对荧光增白剂的限量标准不同，以下是部分国家的标准：1.中国：用于制造纸和纸制品的荧光增白剂含量不得超过0.05%（以重量计）。

用于制造洗涤剂的荧光增白剂含量不得超过0.001%（以重量计）。

2.欧盟：对于纸和纸制品，欧盟没有明确规定荧光增白剂的限量标准。

但是，在洗涤剂中，荧光增白剂的含量不得超过0.0005%（以重量计）。

3.美国：联邦法规对荧光增白剂的含量没有明确规定。

但是，一些州对纸和纸制品中的荧光增白剂含量进行了限制，例如加利福尼亚州规定不得超过0.05%（以重量计）。

四、建议为了减少荧光增白剂对人体可能造成的危害，建议：1.避免使用含有荧光增白剂的物品，特别是用于食品包装和儿童玩具的物品。

2.在购买洗衣液等洗涤剂时，选择不含有荧光增白剂的产品。

3.对于含有荧光增白剂的物品，尽量减少接触时间。

4.对于婴儿和孕妇等特殊人群，应特别注意避免接触含有荧光增白剂的物品。

五、总结目前尚无足够的科学证据表明荧光增白剂对人体具有致癌性。

然而，过量接触荧光增白剂可能对人体造成一定的危害，特别是对于特殊人群。

各个国家对荧光增白剂的限量标准不同，但都以保证人体健康为前提。

为了减少荧光增白剂对人体可能造成的危害，建议消费者选择不含有荧光增白剂的产品，并减少接触含有荧光增白剂的物品的时间。

新型荧光增白剂的类型及应用摘要：荧光增白剂是一种应用很广的化工原料．本文介绍了荧光增白剂的增白机理及类型，荧光增白剂在造纸、洗涤剂、织物等领域的应用，概述了荧光增白剂的发展趋势．关键词:光学增白剂应用增白机理发展趋势荧光增白剂又叫光学增白剂, 它可以使白色物体( 如纺织品、纸张、塑料、涂料等) 更白更艳。

它可以将用化学方法不能除去的织物或其它物体上的黄褐色素变为白色, 使白度不理想或带黄色的物体通过荧光增白剂吸收日光中的紫外光部分而发射出蓝色荧光加以补正而变得更白, 它与加蓝增白及化学漂白不同,加蓝虽可增白, 但一则效果有限, 二则亮度要降低; 化学漂白对纤维素有破坏作用, 而且漂白后的物体不可避免地要带有黄色。

但漂白是增白的必要前提, 不漂白直接增白是没有效果的。

光学增白的同时还使亮度或艳度增加。

据广东省科技情报所检索, 这种新型的涤纶荧光增白剂在国内尚未有厂家生产, 这一产品填补了国内空自, 预期将会取得较好的经济。

英国物理学家George Gabriel Stokes 于1852 年首次从理论上阐述了荧光现象，奠定了荧光增白新方法的理论基础．荧光增白剂（Fluorescent Whitening Agent，FBA）是一种重要的功能性助剂，是一种无色的有机化合物，能吸收紫外光（波长范围在300 ～ 400 nm 之间），再发射出人肉眼可见的蓝紫色荧光（波长范围在420 ～ 480 nm 之间），与基质上的黄光互补而具有增白效果[1]． 1929 年，德国人Krais首先采用七叶树素的浸出液处理黏胶和半漂白亚麻，以获得增白[2]. 但是，Krais 的发现并没有被应用于实际，因为七叶树素溶液对纤维素纤维没有亲合力，被它处理过的材料耐光性和耐洗性都很差．直到1940 年德国IG 公司提出了具有实用型的荧光增白剂后，其商品化历程才真正开始．目前，世界上己报道的荧光增白剂约有15 种基本结构类型．据不完全统计，我国目前开发、研究和生产的不同结构和性能的荧光增白剂有40 多个．不同品种的荧光增白剂有不同的理化性质，也有不同的使用条件和应用对象[3,4]．研发高效、节能、环保的荧光增白剂是目前热点之一．1 荧光增白剂的增白原理与结构特征白色物质一般对可见光中450 ～ 480 nm 的蓝光有轻微吸收，而造成蓝色不足，使其稍带黄色而给人以陈旧之感．为此，人们采取了不同的措施来使物品增白、增艳．通常采用的方法有：①加蓝增白法．加蓝可以增白，但效果有限，而且由于总的反射光量减少，使物品色泽变暗．②化学漂白法，主要是通过氧化还原反应而使物质褪色，因此对纤维素会造成一定的破坏，而且漂白后的物体常带黄色，影响增白效果．上世纪30 年代发现的荧光增白剂弥补了上述方法的不足，并显示了巨大的优越性．荧光增白剂吸收能量较高的近紫外光线使其分子进入激发态，然后被激分子跃迁到能量较低的基态，并发射出荧光．由于发生了能量损失，幅射的荧光波长变长，大约为450 nm 的蓝光，泛黄物品的黄色可以被荧光增白剂反射出来的蓝光补偿，从而增加了物品的表观白度．由于发射光的强度超过了投射于被处理物上原来可见光的强度，所以产生了略带色光的增白效果．具有实用价值的荧光增白剂，除了吸收紫外光而发出紫蓝色的荧光和具有高的荧光效率外，本身还必须接近无色或微黄色，具有普通染料的特性，对被增白的物质如纤维有良好的亲和力、良好的溶解性或分散性能以及较好的耐洗、耐晒和耐烫等牢度性能．荧光增白剂的增白特性是由其分子的特殊结构决定的[5]．它的发色基团具有可发生π→π* 跃迁的共轭体系，最常见的这些体系有苯环、萘环、三嗪环、乙烯基、五元杂环和其它一些稠环体系．共轭程度小的电子体系一般只吸收很短波长的光，随着共轭体系增大，可吸收光的波长增大，电子就越容易被激发，增白剂的荧光效率越大，从而满足荧光增白剂的要求．为了改善荧光增白剂综合使用性能，还需引入助色基团，包括推电子基（如烷氧基、烷基、取代氨基等）和拉电子基（如磺酸基、氰基、羧基等），这些基团会影响荧光的性质与强度．有些基团对发色系统的影响较小，但可改变荧光增白剂的应用性能及对纤维、塑料等的亲和力．在荧光增白剂的结构中不能含硝基、亚硝基或重氮基团，虽然它们能提高日晒牢度，但这些基团会减弱甚至完全猝灭荧光．2 荧光增白剂的类型荧光增白剂种类繁多，可以按母体化学结构或使用用途等对其进行分类．按用途常分为：①洗涤剂用荧光增白剂；②纺织品荧光增白剂；③造纸用荧光增白剂；④塑料和合成材料用荧光增白剂；⑤其他用途的荧光增白剂．按母体化学结构可分为15 种基本化学结构类型，其中主要有五大类[6]：①二苯乙烯类，具有蓝色荧光；②吡唑啉型，具有绿色荧色；③香豆素型，具有香豆酮基本结构，有较强的蓝色荧光；④苯并氧氮茂及苯并噁唑型，具有红色荧光；⑤萘酰亚胺类，具有蓝色荧光．3 荧光增白剂的应用荧光增白剂的用途非常广泛，由最初的仅用于纺织品发展到现在主要用于造纸、洗涤剂、塑料、涂料、油墨、皮革等领域．目前，在非纺织品上的用量远大于在纺织品上的用量[5]．下面主要介绍荧光增白剂在造纸、洗涤剂和纺织品中的应用．3．1 荧光增白剂在造纸中的应用在造纸工业中，荧光增白剂是非常重要的添加剂之一，有人形象地把荧光增白剂比作造纸工业的“工业味精”，是生产高白度、高品质纸产品必需使用的功能性助剂[7-8]．添加了荧光增白剂后制备的纸张，白度可提高10％以上[9]．因为纸的主要成分是纤维素纤维，对纸进行增白，通常采用在打浆、施胶、表面涂布的造纸过程中应用．不同的工艺，应选用性能不同的荧光增白剂．用于造纸工业的荧光增白剂至少应满足以下条件：①与各种造纸用化学试剂有良好的相容性，也就是说，荧光增白剂的加入不会导致纸品质量下降；②能耐一定的酸碱度，能耐化学漂白后纸品中残留氯的影响，能适应造纸工艺过程的需要，也就是说，要有良好的化学稳定性；③对纸纤维有亲和力，有较高的白度，对环境无害等．3．2 荧光增白剂在洗涤剂中的应用洗涤剂是人们日常生活中的必需品．随着生活水平的提高，人们对洗涤剂的需求也不断提高，并朝着环保、方便、经济、高效的方向发展[13]．表面活性剂和助剂是洗涤剂的主要成分，关系到洗涤剂的性能．目前世界上荧光增白剂消费量的50 ％是用于洗涤剂行业．3．3 荧光增白剂在织物上的应用荧光增白剂最初用于纺织纤维领域，至今已有近70 年的历史．由于纤维有纤维素纤维、蛋白质纤维和合成纤维三大类，所以，在使用荧光增白剂时，必须先了解纤维的化学组成和物理性能，以便以准确地选择合适的荧光增白剂，从而得到满意的增白效果[15]．用于纺织纤维工业的荧光增白剂至少应满足以下条件：①对纤维无损伤，并与其有较好的亲和力；②具有较好的水溶性；③有良好的化学稳定性；④有较好的均匀增白性；⑤对环境无害等．3．4 其他应用随着塑料工业的蓬勃发展，人们对塑料制品的外观性能要求不断提高，因此用荧光增白剂来改善塑料制品的外观性能已越来越受到关注[16-18]．荧光增白剂除了在上述各领域的应用外，还应用到了珍珠增白[19]、涂料、皮革等[5]．选取何种类型的荧光增白剂需要根据具体应用情况而定．在应用时，要充分考虑增白剂的应用条件，如pH、温度、湿度和增白效果，才能达到理想的增白效果．参考文献[1]Naik S N, Poro S S.

Soap clean if skin contaminated.Packing:25kg / fiber drum with PE linerOptical Brightener Odyssey OB-1 （荧光增白剂OB-1）Optical brighteners are added to many materials to reduce yellowing, improve whiteness, and to enhance the brightness of a product. Odyssey OB-1 is used widely in the plastic market. Because of its excellent brightening ability,good thermal stability,and compatibility with many polymers. Typical PropertiesChemical name: 2,2-(1,2-Ethenediyldi-4, 1-phenylene) bisbenzoxazoleMolecular weight: 414.4CAS No.: 1533-45-5C.I.: 393Specifications:Ash %Empirical FormulaMelting Point(DTA),CAppearanceOdorV olatile Content %Assay %Particle Size0.3maxC28H18N2O2353-359Y ellowish Green PowderFree of odor0.3max99min200 meshesEffect of Optical Brighteners on the Whiteness of PolymersOptical brighteners function by absorbing ultraviolet radiation and remitting blue light. The emitted blue light will reduce the yellow color of a polymer. In the presence of a whitening agent, such as TiO2, the use of Odyssey OB-1 will produce a brilliant white o r “white than white” appearance.Two primary factors affect the whiteness/yellowness of a formulation. They are the color of the base polymer and the level of brightener added. If no whitening agent, such as TiO2, is used, the level of Odyssey OB-1 required will likely be lower than when a whitening agent is preset. This level might be as little as 25-50 ppm. In determining the optimum concentration of brightener, the effect of any other UV-absorbing materials in the plastic should be considered. It is important that users perform sufficient evaluations to determine the optimum level of Odyssey OB-1 for their specific end uses.Methods of AdditionTo be effective, an optical brightener must dissolve in the polymer to which it is added. Since the typical addition levels for Odyssey OB-1 in the range of 100-400 ppm, the use of a concentrate, or masterbatch, is recommended. Concentrates are containing 1%-10% by weight of Odyssey OB-1 typical.The concentrate can be produced on an extruder using normal processing conditions for the polymer, including drying if necessary. The concentrate is then let down to typical use levels in the final formulation. Plastics compounding equipment is normally adequate for producing Odyssey OB-1 brightener formulations. The key requirement is to thoroughly disperse the brightener so that it will dissolve uniformly throughout the molten polymer. This is usually achieved most readily with a concentrate.Improving Whiteness of Recycled PolymerThe business of processing post consumer plastics and waste polymer continue to grow. These materials can be recycled into a variety of useful products, from plastic lumber to synthetic fiber. Polyester bottle polymer, polyester plastic waste, and waste fiber polymer can be recycled into polyester fiber that can be used in carpets, filling and insulation material, nonwovens, and apparel. One of the shortcomings of processing these materials is the uncertainty of the color of the source material.By using optical brighteners, the value of the recycled materials can be significantly enhanced by providing a more uniform white. Odyssey OB-1 will greatly improve the whiteness, Normal fiber applications require only 200-300 ppm in new polymer, but recycled material may require as much as 300-450 ppm. Optical brighteners are very effective in improving the appearance of the polymer or fiber.

中国的荧光增白剂纺织品国标主要规定的是纺织品中荧光增白剂含量的测定方法和限量要求。

这个标准适用于含有荧光增白剂的棉、麻、毛、丝、化纤、混纺及其他纤维纺织品。

具体来说，对于棉、麻、毛和丝绸类纺织品，按干重计算，荧光增白剂含量不得超过150mg/kg；对于合成纤维类纺织品，按干重计算，荧光增白剂含量不得超过100mg/kg。

此外，新版的国标GB/T 10661-2021《荧光增白剂VBL (C.I.荧光增白剂85)》也有一些主要变化，比如标准名称的修改，增加了CASRN号，合并了用于纺织品和用于造纸两个规格，修改了检验项目中的“相对强度”和“白度”为“增白强度”，增加了重金属元素的量指标和试验方法，以及增加了增自强度的试验方法等。
