Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), are chemical compounds that absorb light in the ultraviolet and violet region.

These additives are often used to enhance the appearance of color of fabric and paper, causing a “whitening” effect.
