　　Properties:

　　Optical Brightener CXT is regarded as one of the perfect agent used in detergent industry. Because of the morpholine group be introduced 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 nionic characters and has optical blue color. It has better resistance to chloride bleaching than VBL and 31#,the most favorable dyeing bath pH value is 7-10.Its sunlight resistance is 4 grade. The most advantage used in detergent industry is its high matching capacity, high accumulated washing whiten effect. So it can satisfy the requirements of various 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 whiten effect on artificial fiber, polyamide, vinylon, also has well whiten effect on casein fiber, amide plastic.

　　Properties:

　　Optical brightener CXT has less solubility than VBL and 31#, it can be solved with hot water and form about 10% solution. It should be used immediately when the solution is ready and avoid sunlight The dosage used in detergent industry is 0.1-0.5%,in dyeing industry is 0.1-0.3%.

　　Packing: Packed in cardboard bucket or cardboard box after being packed in plastic bag first.Net Weight per bucket is 20kg or 25kg.

　　Transportation: Should avoid sunlight and crash.

　　Storage: Should be stored in cool, dry and ventilate place, stored time shouldn`t exceed 2 years.
