Performance characteristics: Fluorescent Brightener Agent CXT is an excellent fluorescent whitening agent for detergents. Many properties of the whitening agent have been improved by introducing morpholine group into the molecule. For example, the acid resistance is increased, and the perborate resistance is also good. It is suitable for whitening cellulose fibers, polyamide fibers and fabrics. The ionization of fluorescent whitening agent CXT is anionic and the fluorescent tone is blue. The chlorine bleaching resistance of fluorescent brightener CXT is better than that of VBL and 31 #. The best dyeing bath has PH=7-10 and its light fastness is grade 4. The greatest characteristics of CXT used in laundry powder are: high mixing amount, high accumulated whiteness, and can meet the requirements of any mixing amount in detergent industry.
Scope of application:
1. It is suitable for detergents. When mixed with synthetic laundry powder, soap and soap, it can make its appearance white and pleasant, crystal and plump.
2. It is used to whiten cotton and nylon fabrics. It has excellent whitening effect on man-made fibers, polyamide and vinylon. It also has good whitening effect on protein fibers and amino plastics.
