Optical Brighteners
Optical Brightening Agents or Fluorescent Whitening Agents are
added to many substrates to reduce yellowing, improve whiteness and
enhance the brightness of the product. Optical whiteners function by
absorbing ultraviolet radiation and re-emitting blue light. The
emitted blue light will reduce the yellow color of the substrate and
impart a pleasing whiter-than-white appearance. Optical brighteners
give more intensity to some colors as well.
Different types of Optical Brightening Agents find suitable
application on different substrates like
Detergent,
Fiber,
Paper,
Plastic and
Textile.
