Performance characteristics:
Fluorescent brightener CXT is considered to be an excellent brightener for detergent. Due to the introduction of morpholine gene into this brightener molecule, many properties of it have been improved. For example, the acid resistance is increased, and the performance of perborate is also very good. It is suitable for whitening cellulose fibers, polyamide fibers and fabrics. The ionization property of fluorescent brightener CXT is anionic, and the fluorescence tone is cyan. The chlorine bleaching resistance of fluorescent brightener CXT is better than that of VBL and 31#, the pH of the best dyeing bath is 7 ~ 10, and its light fastness is grade 4. CXT used in washing powder is characterized by high mixing amount and high accumulated washing whiteness, which can meet any mixing amount requirements of detergent industry.
