Fluorescent Whitener and Our Daily Life

Fluorescent whitening agent is a fluorescent dye, or white dye, and also a complex inorganic compound. The characteristic of fluorescent whitening agent is that it can stimulate the fluorescence of incident light, make the dyed substance achieve the effect of similar fluorite flash, make the substance seen by the naked eye very white, and achieve the effect of whitening.

Fabrics and other fabrics used to be yellow because of the color impurities. In the past, chemical bleaching was used to stop bleaching. Now, fluorescent whitening agent is added to the fabrics, which complements the original yellow radiation to white light and improves the whiteness of the products under sunlight. Bleaching agents were widely used in acrylic fiber spinning, textiles, paper making, laundry powder, soap, rubber, plastic products, pigments and paints.

Common fluorescent whitening agents can be divided into two categories, one is water-soluble whitening agents, the other is water-insoluble whitening agents. The former can be used as brighteners for paper, paint, detergent and cotton fabrics. Another kind can be used for whitening chemical fibers, plastics, etc.

As early as 2013, five of the six workbooks in Beijing were found to contain fluorescent whitening agents. Not only that, our clothes, lipsticks, washing powder, sanitary napkins, clothes, plastic lunch boxes contain fluorescent agents.

For the sake of safety, parents are advised to check the color of the paper in the bright light when choosing homework books for their children. If the paper is too white and too bright, it is better not to buy it. "Yellow paper is absolutely safe." In addition, parents should teach their children not to put their homework books in their mouths to avoid fluorescent whitening agents being swallowed indirectly by their children.

In our daily life, we are exposed to fluorescent brighteners at many times. Just do not exceed certain norms, will not bring trouble to our lives.
