[0002] Fluorescent whitening agents are a class of chemicals commonly used in industries such as textiles, papermaking, plastics, and detergents. They are also called brighteners, whitening agents, or fluorescent bleaching agents. The main function of fluorescent whitening agents is to absorb ultraviolet light and then re-radiate blue or purple light to make the surface of an object look whiter and brighter. Fluorescent whitening agents improve the whiteness and brightness of materials through optical effects, masking or reducing the effects of yellow or gray. They are widely used in many fields, including textiles, paper, plastic products, detergents, leather, inks, etc.
