• Optical brightening agents are generally used in
  paper industries. The purpose behind this is to
  enhance the whitening effects on paper. These are
  additives added to the paper to make them look
  whiter than their natural selves.
• It is common for most manufacturers to add
  optical brighteners for paper or optical
  brightening agents as they are known. These are
  helpful in adding certain chemicals to the paper
  for it to take the invisible, ultraviolet light.
• This also causes the paper to emit a blue
  spectrum seen as blue-ish white to the human eye.
  Also, this is one of the reasons why printer
  profiles made with a lot of optical brighteners
  end up printing images with a yellow tint to
  them.

• These optical brightening agents are also the
  reason why over the years, the paper has lost its
  glow. So, with time, let us say a time period of
  several months or even years, the apparent
  brightness of the paper decreases drastically,
  giving it a dull look.
• Some people choose to print natural papers, and
  others choose to print using Optical Brightening
  Agents.

How to check if your paper has Optical
Brightening Agents?

• The best way to prevent this is to shine a black
  light on the paper. The black color will make the
  optical brighteners glow. This effect can even be
  seen on a white cloth when you shine a black
  light on it.
• The reason is that a paper that does not have
  optical brightening agents will not react at all
  to the black light projected upon it. Optical
  brightening agents also have a high melting
  point, allowing them to mix with molten plastic
  to give any shade very quickly.

Where are Optical Brightening Agents used?

• Optical Brighteners for paper are also used in
  more than just manufacturing paper. Its other
  uses are
• Laundry detergent
• Plastics
• Paints
• Cosmetics
• They are used in every industry for commercial as
  well as domestic use. They give the final
  products a unique and different finish. Recycled
  paper also needs a good amount of optical
  brightening agents to improve the color and make
  it look cleaner.

Conclusion

• Optical brighteners for paper are used majorly in
  the industry. The most significant advantage is
  that the manufacturers of paper and paper mill
  owners get the opportunity to provide the
  shiniest, brightest, and whitest papers to their
  customers.
• Papers looking dull dont sell, and the customers
  quickly switch to a different competitor waiting
  to grab the opportunity.
