Performance characteristics:

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