The optical beightener CBS-X is different from the fluorescent brightener CXT DMS in that it is mainly used in high-end synthetic laundry detergents, super concentrated liquid detergents, and can also be used in the whitening of soaps and toilet soaps. Its raw material DSD acid supplies 75% to China, and the other 25% is concentrated in India.
Therefore, China's optical brighteners CBS-X and C.I 71 have the stability and price advantage of continuous supply.

Usage and dosage
Optical Brightener CBS-X is widely used in detergents, soaps, and textile applications to enhance whiteness and brightness. It is highly effective in low concentrations and provides a brilliant bluish-white effect. In laundry detergents, the recommended dosage is typically 0.05%–0.3% depending on the formulation and fabric type. For textile applications, the usage level ranges from 0.1%–0.5% on weight of fabric. CBS-X should be added during the liquid or powder formulation stage for best performance. Proper dispersion is essential to achieve uniform whitening results and avoid uneven brightness on treated materials.
