How to distinguish the quality of
1. Light or even no odor is an indicator of high quality sodium hydrosulfite. Because the odor comes from SO2 contents in SHS, and less SO2 menas slow decomposition and more stability.
2. The optimal Ph Value of Sodium hydrosulfite sits at 6-7. Only when the sodium hydrosulfite Ph value sit at 6-7, the bleaching effect of SHS can be exerted at best.
3. Less impurity the sodium hydrosulfite contains, more effective when it is used in VAT dyes. Less impurity means higher.
