Optical Brighteners are important raw material in Detergent, Textile, Paper industries. DMS, CBS are mainly used for detergent field, such as: DMS is regarded as one of the perfect agent used in detergent industry, owing to introducing the morpholine group into the molecular, the properties such as acid and perborate resistance be improved. It can be used in the whitening of cellulose fiber, polymide fiber and fabrics, showing anionic characteres and has optical bule color, it has better resistance to chloride bleaching than VBL and 31#, the most favorable dyeing bath PH value is 7-10.
BA & BBU mainly are used for paper industry.
