Performance characteristics:
Fluorescent brightenerCXTIt is currently considered to be an excellent fluorescent whitening agent for detergents. Due to the introduction of morpholine groups into the whitening agent molecule, many of its properties are improved. For example, acid resistance is increased,Very good resistance to perborate,Suitable for whitening cellulose fibers, polyamide fibers and fabrics. Fluorescent brightenerCXTThe ionization property is anionic,The fluorescent hue is cyan.CXTGood resistance to chlorine bleaching,Better thanVBLand31＃,Use the best dye bathPH＝7～10, its light fastness is4class.CXTThe biggest feature of using it in washing powder is: high compounding amount, high accumulated washing whiteness, and it can meet any compounding amount requirements of the detergent industry.
Scope of application:
1, Suitable for detergents, added to synthetic washing powder, soap, and perfumed soap to make their appearance white, pleasing to the eye, crystal clear and plump.
2, used for whitening cotton fibers, nylon and other fabrics; has excellent whitening effect on artificial fibers, polyamide, and vinylon; also has good whitening effect on protein fibers and amino plastics.
Directions:
Fluorescent brightenerCXTSolubility in water is higher than that of brightenerVBLand31# Low, can be adjusted with hot water10%When preparing a solution, it should be used immediately after preparation and the solution should be kept away from direct sunlight.CXTThe dosage in washing powder is0.1-0.5%; The amount used in the printing and dyeing industry is0.1-0.3%。
Package: 10kg or 25kg carton or drum. Can be customized according to customer needs.
transportation:Fluorescent brightenerCXTThe product should be transported away from collision and exposure.
Storage:It should be stored in a cool, dry and ventilated warehouse with a storage period of two years.
