Optical brightening agents (OBAS), 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.

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.
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. This initial brightener gets progressively removed by successive washes. The optical brightener’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.
There are two processes for the production of optical brightener cbs-x. One is the biphenyl methylation—witting method: biphenyl is used as raw material, through chloromethylation, esterification, and condensation. The other is the diazotization-heck method: using halogenated benzene as raw material, it is synthesized by reacting with olefin compounds under a palladium catalyst.

Applications

Industry Use
The primary purpose of detergent brighteners in laundry detergent formulas is to make the clothes appear visually cleaner/whiter/brighter. In this field, optical brighteners have proven more advanced solutions compared to bleaches and bluing, formerly used to produce the same effect but with consequences.
Consumer use
White fabrics, in particular, tend to show signs of weariness over time, and extensive washing leads to a yellowish appearance. Optical brighteners extend the lifespan of such fabrics, improving their visual properties with almost no adverse effects.
Obas have a range of applications in cosmetic industry formulas. It’s one of the common ingredients in shampoos and conditioners for gray or blonde hair, where they enhance the luminance of strands and correct unwanted tones or discoloration. Some face foundation formulas contain oba microspheres to improve the complexion and mask the dark areas.
