Molecular weight: **4.*1 (as international relative atom mass ***5)
Max UV absorption wavelenghth: **0nm
Excutive standard: Hg/t********7

Property:
Optical brightener cxt 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 resistence to chloride bleaching than vbl and *1#, the most favorable dyeing bath pH value is ***0. Its sunlight fastness is 4 grades. The most advantage used in detergent industry is its high matching capacity, high accumulated washing whitening effect. So it can meet the requirements of any matching capacity in detergent industry.

Application:
1. Used in detergent industry, for the synthetic detergent, toilet soap and soap.
2. Used in the fabric of cotton fiber, nylon, etc, taking on excellent whitening effect on artificial fiber, polyamide, vinylon, also has good whitening effect on protein fiber, amino plastic.

Procedure:
Optical brightener cxt has less solubility than vbl and *1#, it can be soluble in hot water and form about *0% suspension liquid. The liquid should be used immediately when ready and avoid sunlight. The dosage used is 0.**0.5% in detergent industry and 0.**0.3% in dyeing industry.

Package:
Packed in cardboard bucket or cardboard box after being firstly packed in plastic bag. Net weight per bucket is *0kg or *5 kg.

Transportation:
Should avoid sunlight and crash.
