性能特点：
荧光增白剂CXT是一种目前被认为是洗涤剂用的优良荧光增白剂。由于这种增白剂分子中引入吗啉基团，使其许多性能得到改善。例如耐酸性能增加,耐过硼酸盐性能也很好,适用于纤维素纤维、聚酰胺纤维及织物的增白。荧光增白剂CXT的电离性表现为阴离子性质,荧光色调为青光。荧光增白剂CXT的耐氯漂性能较好,优于VBL和31＃,使用最佳染浴的PH＝7～10，其耐晒牢度为4级。CXT用于洗衣粉中最大特点是：配合量高，积累洗涤白度高，能满足洗涤剂工业任何配合量的要求。
适用范围：
1、适用于洗涤剂，配入合成洗衣粉、肥皂、香皂中，能使其外观洁白悦目，晶莹丰满。
2、用于棉纤维、尼龙等织物增白；对人造纤维、聚酰胺、维尼纶有优良的增白效果；对蛋白纤维、氨基塑料也有良好的增白作用。
使用方法：
荧光增白剂CXT在水中的溶解度比增白剂VBL和31＃低，可用热水调成10%左右的悬浊液使用。配成溶液时，宜随配随用，溶液应避免阳光直射。荧光增白剂CXT在洗衣粉中用量为0.1-0.5%；在印染行业用量为0.1-0.3%。
包装: 用铁桶或纸桶内衬塑料袋，每桶净重20kg或25kg。
运输：荧光增白剂CXT产品运输时应避免碰撞和曝晒。
贮存：应贮存于阴凉、干燥、通风的库房内，贮存期两年。

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 goodwhitening 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 iron drum or cardboard bucket after being packed in plastic bag first. Net weight per bucket is20 kgor25 kg.
TRANSPORTATION: Should avoid sunlight and crash..
STORAGE: Should be stored in cool, dry and ventilate place, and storage time
