| Product name: | Optical Brightener CXT | |
| CAS： | 16090-02-1 | |
| C.I.NO: | 71 | |
| Structure: |  |
|
| Molecular formula: | C40H38N12O8S2Na2 | |
| Substance name： | Disodium 4, 4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate | |
| Molecular weight : | 924.93 (As International relative Atom Mass 1997) | |
| Max UV absorption wavelenghth: | 350 nm | |
| Excutive standard: | HG/T3675-2010 | |
| Specification: | Item | Indices |
| Appearance | White or light yellow even powder | |
| E11 (UV absorption) | ≥ 370 | |
| Whitening strength | 100 | |
| Color Shade | similar | |
| Moisture content | ≤ 5.0% | |
| Content of water-insoluble impurities | ≤ 0.5% | |
| Fineness (residual content passed through 180μm-pore sieve) | ≤ 5.0% | |
| 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 resistence 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 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 requirments 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 whitening effect on artificial fiber,polyamide, vinylon, also has good whitening effect on casein fiber, polyamide plastic. |
|
| Procedure: | Optical brightener CXT has less solubility than VBL and 31#, it can be soluble in hot water and form about 10% 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. | |
| Package: | Packed in carton box after being packed in plastic bag first or Kraft bag. Net weight per carton box/craft bag is 25 kg or 20 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. | |
