    Optical Brightener DMS is regarded as one perfect agent used in detergent industry.Because it induce one morpholine base into its molecular,thus improved its properties.such as improved its acid and perborate resistence. It can be used in the whitening of cellulose fiber, polyamide fiber and show nionic characters and has optical blue color. It has better resistence to cholride bleaching than VBL and 31#, the most favorable dyeing bath PH value is 7-10.its sunlight resistence is 4 grade.The most advantage it used in detergent industry is its high matching capacity,high accumulated washing whitening effect.So it can meet the requirments of various matching capacity in detergent industry.

    1. Fluorescent whitening agent for detergent industry.the synthetic detergent and soap will have better aspect after usage of this agent.
    2. Fluorescent whitening agent for the fabric of cotton fiber, nylon, etc. Has excellent whitening effect on artificial fiber, polyamide, vinylon, also has good whitening effect on casein fiber, amide plastic.
    Optical brightener DMS has less solubility than VBL and 31# and can be soluable in hot water and form 10% turbid solution. The solution should be used immediatly when it is ready and avoid sunlight. The dosage used is 0.1-0.5% in detergent industry and 0.1-0.3% in dyeing industry.
