Tetrasodium Pyrophosphate, abbreviated as TSPP, also named sodium pyrophosphate, with molecular formula (Na₄P₂O₇) and CAS No. 7722-88-5. Manufactured strictly by Chuandong Chemical with mature phosphate synthesis technology, our TSPP appears as white crystalline powder or granules, odorless, highly soluble in water while insoluble in ethanol. Its aqueous solution shows weak alkalinity with pH value 9.9–10.7 (10g/L solution) and possesses prominent chelating, buffering, emulsifying, dispersing and water retention capabilities.

　　Chuandong Chemical provides two mainstream specifications: Food Grade TSPP and Industrial Grade TSPP. Our products have stable purity, low heavy metal residue and excellent anti-caking performance, supporting long-term stable use for global manufacturers across Europe, Southeast Asia and Central Asia.

       Core Functional Advantages of Chuandong TSPP

　　Strong Metal Chelation: Effectively chelate Ca²⁺, Mg²⁺, Fe³⁺ ions, eliminate water hardness, avoid precipitation and turbidness in formulas, extend finished product shelf life.

　　Excellent Water Retention & Texture Modification: Combine with meat protein molecules to lock moisture, improve tenderness and yield rate of meat & seafood products.

　　Stable pH Buffering: Maintain stable system alkalinity during high-temperature processing, protect product flavor and organizational structure from pH fluctuation.

　　Good Dispersion & Emulsification: Disperse solid particles evenly in slurry systems, stabilize oil-water emulsion to prevent stratification for detergents and food sauces.

　　Low Hygroscopy & Stable Storage: Strict dehydration control in production process reduces moisture absorption tendency, effectively preventing material caking during transportation and storage.

       Wide Industrial & Food Application Scenarios

       Food Grade TSPP (E450(iii)

　　Meat & Aquatic Products: The most common moisture retention agent for ham, sausage, canned meat, frozen shrimp and surimi products. Improve cooking yield, keep meat juicy, restrain fat oxidation and discoloration during cold storage.

　　Dairy & Processed Cheese: Act as emulsifying salt to realize uniform melting of cheese, prevent oil-water separation and improve ductility of finished cheese.

　　Beverages, Ice Cream & Sauces: Stabilize emulsion system, improve texture of ice cream, avoid layering of salad dressing, ketchup and jam.

　　Potato & Canned Food: Chelate iron ions to prevent potatoes from blackening after heating, stabilize color and texture of canned fruits and vegetables.

       Industrial Grade TSPP

　　Electroplating Industry: High-efficiency complexing agent for cyanide-free electroplating, optimize plating layer uniformity and surface gloss for metal workpieces.

　　Detergent & Daily Chemicals: Key builder for industrial cleaners, laundry powder and toothpaste. Soften hard water, enhance dirt removal capacity, inhibit dental tartar formation in oral care products.

　　Water Treatment: Scale inhibitor and corrosion inhibitor for circulating pipeline water system, reduce equipment fouling and pipeline corrosion.

　　Ceramic & Building Materials: Dispersant for ceramic slurry, reduce slurry viscosity, improve fluidity and molding quality of ceramic blanks.

　　Textile & Paper Industry: Bleaching auxiliary agent for textile wool degreasing; paper fiber bleaching additive to promote uniform bleaching effect.

　　Drilling Fluid & Metallurgy: Used as mud deflocculant in oil drilling and surface treatment agent for metal rust removal.
