Introduction to Optical Brighteners
Optical brighteners, also known as fluorescent brighteners or fluorescent whitening agents, are chemical compounds that absorb light in the ultraviolet and violet region (usually 340 - 370 nm) of the electromagnetic spectrum and re - emit light in the blue region (usually 420 - 470 nm). This process effectively increases the amount of visible light reflected from the surface of materials, making them appear whiter and brighter.
Optical brighteners are widely used in various industries. In the textile industry, they are used to enhance the whiteness and brightness of fabrics, giving them a more attractive appearance. In the paper industry, they can improve the visual quality of paper products, making them look cleaner and more appealing. They are also used in detergents to make washed clothes look brighter and whiter. Additionally, they find applications in plastics, paints, and cosmetics.
