Optical Brightener -1 is added to many materials to reduce yellowing, improve whiteness, and to enhance the brightness of a product. OB-1 is used widely in the Polymers because of its excellent brightening ability, good thermal stability, and compatibility with many polymers. Optical brighteners function by absorbing ultraviolet radiation and remitting blue light. The emitted blue light will reduce the yellow colour of a polymer. In the presence of a whitening agent, such as TiO2, the use of OB-1 will produce a brilliant appearance. OB-1 complies with regulations for indirect food additives
