Application:
1. Starch modifier; juice turbidity inhibitor; water retention agent; water softener; meat binder; dispersant; stabilizer (used in ice cream, cheese, etc.); it can prevent food discoloration and vitamin C decomposition. It is also used as a water softener.
2. It can be used to produce low-density washing powder, and can also be used to produce dry bleach, automatic dishwashing detergent, sodium tripolyphosphate hexahydrate, and a mixture of sodium tripolyphosphate hexahydrate and inert inorganic salts.
3. It can be used to produce gypsum board for building materials, etc.
  Packing:It is packed with polyethylene bag as inner, and a composite paper bag as the outer layer. The net weight of each bag is 25kg.
