What Is A Fluorescent Whitening Agent

- May 31, 2019-

The combination of fluorescent whitening agent and detergent began in 1940. Although it is not used in detergents, its whitening and brightening effect is very obvious, so it has been favored by the detergent industry.

The fluorescent whitening agent is a fluorescent dye which, under the irradiation of ultraviolet light, can excite blue and violet light and complement the yellow light on the substrate to have a whitening effect. (GB/T 6687-2006 dye terminology)

Fluorescent whitening agents are also known as "optical brighteners" because they use optical complementary color to whiten, brighten, and brighten white or light-colored substrates (such as textiles, paper, plastics, etc.). "White fluorescent dye" and the like.
