Optical brightening agents (OBAs), also known as fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs) are chemical compounds that give a whitening effect to the fabric. They do this by absorbing light in the ultraviolet and violet region and re-emit the light in the blue region. Fluorescent activity is a short-term or rapid emission response, unlike phosphorescence, which is a delayed emission. This blue light reduces the yellow color of the substrate and gives a bright look. At Meghmani, you will find the ideal and quality Optical Whitening Agents.
