CBS-X is a high-performance optical brightening agent (OBA) widely used in detergents, textiles, and paper to enhance the whiteness and brightness of substrates. It works by absorbing ultraviolet light and re-emitting it as visible blue light, which neutralizes yellowish tones and gives materials a cleaner, brighter appearance.
CBS-X is highly effective at low concentrations, exhibits excellent solubility, and performs well in both hot and cold water, making it ideal for laundry detergents and liquid detergent formulations.
