Fluorescent BrightenerHexasulfonic AcidIt can dissolve uniformly in water at any ratio under any conditions and quickly disperse evenly in pulp, ensuring stable quality of the finished paper. The finished paper is less prone to yellowing. Due to the high yellowing point of hexasulfonic acid, it allows for continuous layering and cumulative whitening, achieving a higher visual whiteness.
