                                Chemical Name:

                                Tetrasodium pyrophosphate

                                Molecular Formula:

                                Na4P2O7

                                Molecular Weight:

                                265.90

                                CAS:

                                13472-36-1

                                Character:

                                Colorless clear crystal or white crystalline powder. The relative density is 2.534 and melting point is 880°C. It easily soluble in water and insoluble in ethanol. It will weathering in dry air and lose crystal water under 100°C. It easily absorbs water to deliquesce in air.

                                Uses:

                                It is used as quality improver, regulator of PH value, chelate agent, emulsifier and binder in food industry. It also is used in the processing of meat and aquatic product.

                                Packing:

                                It is packed with polythene bag as the inner layer, and a compound paper-plastic woven bag as the outer layer. The net weight of each bag is 25kg.

                                Storage & Transportation:

                                It should be stored in a dry and ventilative warehouse, kept away from water and moisture during transport. Unload with care as to avoid being damaged. Furthermore, it must be stored separately from poisonous substances.
