Optical Brightener Agent
Synonym name: Optical brightener sometimes called optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents (FWAs).
How does optical brightener agent work?
Mechanism: Optical brighteners are colorless to weakly colored organic compounds. When present on a substrate, optical brighteners absorb primarily invisible ultraviolet light in the 300-400 nanometer (nm) range and re-emit in the visible violet-to-blue fluorescent light to yield a brighter, fresher appearance. They are designed to brighten colors or mask yellowing in plastics, lacquers, paints, inks, photo-processing solutions, and fibers.
