Optical brighteners or fluorescent whitening agents (FWAs) are dyes that absorb light in the ultraviolet and violet region of the electromagnetic spectrum, and re-emit light in the blue region. These additives are often used to enhance the appearance of color of fabric and paper, causing a perceived “whitening” effect, making materials look less yellow by increasing the overall amount of blue light reflected.
