Optical Brightener (CBS-X), chemically known as Disodium 4,4′-bis(2-sulfostyryl)biphenyl, is a highly effective fluorescent whitening agent widely used in detergent, textile, and paper industries. It enhances fabric brightness by absorbing invisible ultraviolet light and re-emitting it as visible blue light, making whites appear brighter and cleaner.
At MANNAT ENTERPRISES, we supply high-purity CBS-X Optical Brightener, which provides superior whiteness and long-lasting brightness even after multiple washes. It is compatible with both liquid and powder detergent formulations, stable in alkaline environments, and easily soluble in water.
