Product Detail

Detergent Whitening Agent Optical Brightener CBS X Powder

Today, optical brightening agents (oba) cbs x CI 351 are widely used in washing industry.They are dyes that are absorbed by textile fibers from the solution but are not removed during the washing process. Whitening Agent CBS X and optical brightener CXT convert invisible ultraviolet light into visible light on the blue side of the spectrum, making the fiber reflect more visible light and making it appear brighter. In addition, since the tone of the extra reflected light is on the blue side of the spectrum, this blue-violet hue will complement any yellow on the fiber.It uses physical optics to make the fabric look brighter and whiter.
