Optical Brighteners are chemicals that are mainly used in laundry detergents to make clothes look whiter and brighter. 
They work by converting UV (Ultra Violet) light rays to enhance blue waves and reduce the amount of yellow light. 
This makes the whites look whiter and the colors look brighter. 
They are also used in paper products, cosmetics and printer ink as well as a detection dye when viewed by UV or Black Lights. 

Optical Brighteners are also commonly referred to as Fluorescent Brighteners.

Optical brightening agents (OBAs), or fluorescent whitening agents (FWAs), or fluorescent brightening agents (FBAs) are chemical compounds with the ability to absorb ultraviolet light and re-emit it in the blue region by fluorescence. 
This light-reflecting process provides an effect of extraordinary whiteness/brightness. 

Optical brightener gets absorbed from the formula by textile fibers, without getting removed in rinsing.
For that purpose, they are commonly utilized as additives with a role to enhance the color appearance of fabric and paper through a “whitening” effect. 
By compensating for the deficit in blue and purple light reflected by the material, fluorescent brightening agents minimize the visibility of yellow and orange hues.
Once deposited on fabrics, optical brighteners improve the crispiness of white or light-colored fabrics. 

Even at low levels, their contribution to the overall whiteness performance of the detergent formulas is significant. 
That asset made OBAs a popular ingredient in almost all kinds of detergents. 
Most white fabrics in the market have already been brightened during the manufacturing process. 
Optical Brightener CBS X gets progressively removed by successive washes. 

Optical Brightener CBS X's function in the solution is to take the role of that brightener and gradually replace it while preserving the original features of the fabric.
As the fluorescent material loses energy, some slight changes in color may occur. 
New optical whiteners, applied during the next laundering process, reverse that effect.
Chemically, brighteners are large organic molecules derived from stilbenes or biphenyls.

While the optical brightening agents resemble old-style laundry bluing in several ways, there are significant distinctions between the two methods. 
The first process results in blue dye or pigment absorbing yellow light falling on the fabrics, thus reflecting light richer in blue hues that enhance the brightening effect. 
With the bluing process, however, the material absorbs a portion of the light falling on it, reflecting less light than it receives. 
That leads to a whiter, but not brighter appearance of the fabric.
