Sodium Hexametaphosphate (Food Grade) CAS#10124-56-8
High Solubility: Sodium hexametaphosphate features excellent water solubility, easily soluble in cold and hot water, insoluble in ethanol and other organic solvents, which can be quickly formulated into uniform solution for food processing production.
Stable pH: Its aqueous solution shows weak alkalinity with stable pH value under normal temperature environment, and it will gradually hydrolyze and change property when placed in strong acid condition for a long time.
Versatile Uses: It is widely used as water retention agent, metal ion chelating agent, emulsifier and food quality improver in food industry to improve food texture and extend shelf life.
Crystalline Form & Hygroscopic Nature: This product is white fine crystalline powder with strong hygroscopicity, odorless and non-toxic, conforming to food safety standards, suitable for standardized batching and sealed storage.
Sodium hexametaphosphate, characterized by the molecular formula Na₃PO₄, appears as white odorless crystalline powder with superior chelating and dispersing ability. It has good compounding compatibility, stable physical properties at room temperature, and meets international food additive application standards, safe for food processing use.
