Max UV absorption wavelenghth: 350nm
Excutive standard: Q/lqh010-2006

Property:
Optical brightener AMS is regarded as one 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 31#, the most favorable dyeing bath pH value is 7-10. Its sunlight fastness is 4 grade. 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, aminoplastic.

Procedure:
Optical brightener AMS 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.

Package:
Packed in cardboard bucket or cardboard box after being firstly packed in plastic bag. Net weight per bucket is 20kg or 25 kg.

Transportation:
Should avoid sunlight and crash.

Storage:
Should be stored in cool, dry and ventilate place, and storage time should not exceed 2 years.
