Fluorescent Brightener ER-II is of non-ionicity and does not dissolve in water. It can dissolve in most organic solvents, the color light inclines to blue, its absorption rate is one time faster than the ER-I, its color development temperature is lower than the ER-I and its whiteness is 1.4-1.6 times higher than the ER-I. ER-II is suitable for the terylene chemical fiber, acetate fiber, polyamide fiber and plastics for whitening and blooming.
