Optical Brightener 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, polyamide fiber and fabrics, showing anionic characters and has optical blue color. It has better resistance to chloride beeaching than VBL and 31*, the most favorable dyeing bath PH value is 7-10. Its sunlight fasiness is 4 grades. The most advantage used in detergent industry is its high matching capacit, high accumulated washing whitening effect. So it can meet the requirements of any matching capacity in detergent industry.
Optical brightener DMS has less solubility than VBL and 31*, it can be soluble in hot water and form about 10% suspension liquid. The liquid should be used immediately when ready and avoid sunlight. The dosage used is 0.1-0.5% in detergent industry and 0.1-0.3% in dyeing industry.
