Performance and characteristics:   
  Fluorescence Whitener DMS is suitable for the whitening and brightening of synthetic detergent, cellulose fiber, and paper. The introduction of drewamine instead of gene modifies several performances of this whitener. For example, it has increasing acid and alkali resistance, good perborate and sulfate resistance, better bleaching resistance than that of VBL and 31#; durable, never become yellow.
Application range:
  1. Used in detergent, it can be synthesize washing powder, soap, and fancy soap to make their appearances more white and sightly.
