Features
Fluorescent Whitening Agent CBS-X (C.I. 351) is a styrene-biphenyl derivative and a highly efficient water-soluble fluorescent whitening agent. It absorbs invisible ultraviolet light (340–380 nm) and emits bright blue-violet fluorescence (400–460 nm), which complements the yellow light in the substrate to produce white light, achieving a "blue-supplements-yellow" whitening and brightening effect.
This product exhibits high-efficiency whitening performance on cellulose fibers, polyamide fibers, and other substrates in both cold and warm water, making it one of the most outstanding whitening agents in the detergent industry.
It has high whitening effect on cellulose fiber in cold and warm water.
