The optical brightener DMS is an excellent fluorescent whitening agent currently considered to be used in detergents. Due to

 the introduction of morpholine groups in the molecule of this brightener, many of its properties have been improved.

For example, the acid resistance is increased, and the perborate resistance is also very good. It is suitable for the whitening of cellulose 

fibers, polyamide fibers and fabrics. The ionization of the optical brightener DMS is anionic, and the fluorescent hue is cyan 

light.

The optical brightener  DMS has better chlorine bleaching resistance, better than VBL and 31#. The pH of the best dye bath is 

7-10, and its light fastness is level 4. The biggest feature of DMS used in washing powder is high dosage.

The accumulated washing whiteness is high, which can meet the requirements of any compounding amount in the detergent industry.
