Optical Brightener is based on bis-benzoxazole type organic derivative dispersed in the polymer. These Masterbatches are added in polymers to reduce yellowing, improved whiteness, and to enhance the brightness of a product. These Masterbatches function by absorbing the ultraviolet radiation and re-emitting the blue light. These masterbatches are used in order to mask the natural yellowing of plastics
