Optical Brightener BBU
Good water solubility, soluble in 3-5 times the volume of boiling water, about 300g per liter of boiling water and 150g in cold water. Not sensitive to hard water, Ca2+ and Mg2+ do not affect its whitening effect.
-
Fluorescent Brightener CL
Good storage stability. If it is below -2℃, it may freeze, but it will dissolve after heating and will not affect the use effect; Compared with similar products, it has the same light fastness and acid fastness;
-
Optical Brightener MST

-
Optical Brightener NFW/-L
For reducing agents, hard water has good stability and is resistant to sodium hypochlorite bleaching; This product has average washing fastness and low affinity, which is suitable for pad dyeing process.
-
Optical Brightener EBF-L
The fluorescent whitening agent EBF-L must be fully stirred before use to ensure the whiteness and color consistency of the processed fabric. Before whitening the fabrics bleached by oxygen bleaching, the residual alkali on the fabrics must be fully washed to ensure that the whitening agent is fully colored and the color is bright.
