What are the hazards of fluorescent brighteners?

Fluorescent brightener is harmful to human body \x0d\ Fluorescent brightener is a fluorescent dye, or white dye, and also a complex organic compound. Its characteristic is that it can stimulate the incident light to generate fluorescence, so that the dyed substance can obtain a flash effect similar to fluorite, and the substance visible to the naked eye becomes white, thus achieving the whitening effect. Fluorescent brighteners are widely used in paper industry because they can significantly improve the whiteness of paper. In the production process of napkins, some enterprises also use fluorescent whitening agents to improve whiteness. \x0d\ In recent years, it has been found that fluorescent whitening agents can cause cancer and do great harm to human health, so it is forbidden to use fluorescent whitening agents to make food packaging paper and napkins in the paper industry. \x0d\ There is a simple method to detect whether there is fluorescent whitening agent in napkin. First soak the napkin in water for a while, then put the filter paper strip in it to soak. After the filter paper is dried, check it under ultraviolet light. If the filter paper shows strong fluorescence, the paper sample contains fluorescent whitening agent. It should be noted that this method is fast, but the accuracy is not good. If the amount of fluorescent whitening agent added in the paper sample is small, the inspection effect is not obvious, and it needs to be re-inspected by other methods.
