As the name implies, fluorescent whitening agent is a substance that can emit fluorescence and brighten industrial products. Fluorescent whitening agents, often referred to as "industrial monosodium glutamate", are functional additives necessary for the production of textiles, paper making, washing and plastics.

The raw materials of textile, paper-making, washing and plastic products are not as white as those on the market, and most of them will have the problems of yellowing and dull color. According to the complementary principle of color and light, we can know that the mixture of yellow light and blue light will turn into bright white light. The characteristic of fluorescent whitening agent is that it can absorb ultraviolet light in light and convert it into blue-violet light, which just neutralizes the old yellow light on industrial products and increases its brightness.
