Industrial Phosphate Physical and chemical properties: white powder or crystal. The relative density is 2.534, the melting point is 880鈩? and the boiling point is 938鈩? Colorless transparent crystal or white crystalline powder. It is easily soluble in water, the solubility in 100 grams of water at 20掳C is 6.23, and the aqueous solution is alkaline; it is insoluble in alcohol. The aqueous solution is still stable below 70 掳 C, and hydrolyzed into disodium hydrogen phosphate when boiled. Weathering in dry air, it loses crystal water at 100掳C. It is easy to absorb moisture and deliquescence in the air. It can form complexes with alkaline earth metal ions; in the case of Ag+, it will generate white silver pyrophosphate. Able to complex reaction with metal ions. Its 1% aqueous solution has a pH of 10.0-10.2. It has the general properties of common polymeric phosphates, namely emulsifying, dispersing, preventing fat oxidation, improving protein binding, while inhibiting the oxidation and fermentation of food at high pH. 1. Emulsifier - keeps water and oil mixed together to form an emulsion. 2. Gelling Agents/Thickening Agents - Increase viscosity by thickening liquids, making them more textured. 3. Drugs - used to treat, alleviate, cure or prevent disease. A drug officially declared by a government drug regulatory agency. 4. Chelating agents - bind and remove potentially toxic or unwanted metals 5. Acidity Regulators/Buffers - Change or maintain the pH of food/cosmetics. Tetrasodium pyrophosphate, also known as TSPP, is often used to enhance the flavor of other ingredients. It is also used as a tartar control agent in toothpaste.Packing: 25kg plastic woven bag or kraft paper bag Food grade聽 Sodium pyrophosphate content (Na4P2O7)%鈮?/p 96.5 PH value (1% aqueous solution)9.9-10.7 Heavy metal (calculated as Pb)%鈮?/p 0.00001 Arsenic (As)%鈮?/p 0.000003 Fluoride ((in terms of F mg/kg)%鈮?/p 0.00005 Water insoluble matter%鈮?/p 0.2 Loss on ignition%鈮?/p 0.5 FinenessL.O.IIndustrial Phosphate website:http://www.food-ingredient.net/industrial-additives/industrial-phosphate/
