你知道荧光增白剂常见于我们生活日子中吗?
Do you know that fluorescent whiteners are common in our daily life?
一、荧光增白剂普遍存在于生活日子的各个范畴
I. Fluorescent whitening agents are ubiquitous in all areas of life
我们通常通过是否有荧光反响,去判断荧光增白剂的存在与否。其实,荧光物质普遍存在于自然界中,海里的水母、陆地上的萤火虫都含有荧光物质,乃至人体内的部分氨基酸、维生素A、维生素E等,酱油、普洱茶、咖啡等发酵食物,都能够发生荧光。荧光现象是一种纯粹的冷发光的物理现象,不会对健康发生不良影响。因而,毒性和荧光之间不存在任何关系。
We usually judge the existence of fluorescent whitening agent by whether there is fluorescent response or not. In fact, fluorescent substances are ubiquitous in nature. Jellyfish in the sea and fireflies on the land contain fluorescent substances, even some amino acids, vitamin A, vitamin E in human body. Fermented foods such as soy sauce, Pu'er tea and coffee can fluoresce. Fluorescence phenomenon is a pure physical phenomenon of cold luminescence, which will not have adverse effects on health. Therefore, there is no relationship between toxicity and fluorescence.
和荧光物质一样,荧光增白剂也存在于日子的各个范畴。从开始的纺织品上的运用,发展到现在广泛用于造纸、洗刷剂、纺织品、塑料、涂料、油墨、皮革、防伪、激光探测等多个范畴,乃至运用到生物医药上,而且其运用范畴仍在不断的扩展,与我们的出产和日子密切相关。
Like fluorescent substances, fluorescent whiteners also exist in various areas of the day. From the beginning, the use of textiles has been widely used in paper making, washing agents, textiles, plastics, coatings, inks, leather, anti-counterfeiting, laser detection and other fields, and even applied to biomedicine, and its application is still expanding, closely related to our production and sunshine.

二、荧光增白剂与食盐的急性毒性归于平等等级荧光增白剂在国家标准GB/T6687-2006《染料名词术语》中是这样界说的:“荧光增白剂是一种无色的荧光染料,在紫外光的照射下,可激宣布蓝、紫光,与基质上的黄光互补而具有增白效果”。据了解,荧光增白剂已经有超越75年的运用历史了。纺织品职业是荧光增白剂运用比较早的范畴,天然纤维、合成纤维织物经过褪浆、精粹今后,仍带有微黄色。荧光增白剂在纺织品上能够通过吸收紫外光而宣布蓝紫色荧光的特性中和黄色,从而使织物增白。
2. The acute toxicity of fluorescent whitening agents and salt is attributed to the equal grade fluorescent whitening agents in the National Standard GB/T6687-2006 "Terminology of Dye Terminology": "Fluorescent whitening agents are colorless fluorescent dyes. Under the irradiation of ultraviolet light, they can pronounce blue and purple light excitedly, which complement the yellow light on the substrate and increase it. White effect ". It is understood that fluorescent whitening agent has been used for more than 75 years. Textile industry is the earliest application of fluorescent whitening agent. After desizing and refining, natural and synthetic fabrics will still have a yellowish color. Fluorescent whitening agent can neutralize the blue-purple fluorescence by absorbing ultraviolet light on textiles, thus whitening the fabric.
洗刷剂中添加一定品种、适量的荧光增白剂,不但能改进洗刷剂的外观,一起还能添加洗刷织物的白度或鲜艳度,改进洗刷效果,使白色织物皎白而明亮,使淡色织物鲜艳亮丽。
Adding certain kinds and appropriate amount of fluorescent whitening agent in the detergent can not only improve the appearance of the detergent, but also add whiteness or brightness of the washed fabric, improve the washing effect, make the white fabric bright and bright, and make the light-colored fabric bright.
多年的动物及人体试验标明,即便是皮肤直接接触荧光增白剂纯品,对皮肤也无刺激性,它只会停留在皮肤表面的角质层,不会进入真皮层,可放心运用。依据急性毒性测定数据成果,国标规定能够在洗刷剂中运用的荧光增白剂之一CBS-X与食盐的急性毒性归于平等等级。
Years of animal and human experiments have shown that even if the skin is directly exposed to pure fluorescent whitening agents, it is not irritating to the skin. It only stays in the cuticle layer of the skin surface, does not enter the dermis, and can be safely used. According to the data of acute toxicity test, the national standard stipulates that the acute toxicity of CBS-X, one of the fluorescent whitening agents that can be used in washing agents, is equal to that of salt.
因而,当你在选购洗衣剂时,不必再因为成分表中含有荧光增白剂CBS而心生忧虑,其实荧光增白剂CBS只是一种日常的添加剂而已。
Therefore, when you choose laundry detergent, you need not worry about the fluorescent brightener CBS in the ingredient list. In fact, fluorescent brightener CBS is only a daily additive.
