What is Optical Brightener? Optical Brighteners, or Fluorescent Whitening Agents, are additives that can absorb UV light(yellow light) and emit visible blue light to enhence the whiteness or brightness appearence of white or light colored products, and to lessen the natural yellowing process that happens over time.
Where can use Optical Brightener? Plastics, Detergents, Textiles, Coatings, Inks, and Papers.
Why you need it? Natrual white products emit too much yellow light, so that they look not white and pure enough. And using TiO2 will only cause a dim and dull appearance. Optical Brightener is the best choice! It is not only whiter but also brighter!
