Disodium Phosphate Heptahydrate is a sodium salt of phosphoric acid with the chemical formula Na2HPO4·7H2O. This heptahydrate form is highly soluble in water (up to 11.5g/100ml at 20°C), making it ideal for aqueous applications. CAS Number: 7782-85-6; EINECS: 234-343-4. Its pH in 1% solution is 8.5-9.6, providing excellent buffering capacity.
In the food industry, Disodium Phosphate Heptahydrate serves as a food additive (E339(ii)) for pH control, emulsification, and sequestration. It's crucial in processed cheese to prevent crystallization, achieving meltability without separation – a common issue costing USA processors millions annually. Studies from the Journal of Dairy Science show it improves cheese yield by 15-20% through better moisture retention.
For meat products, it enhances water-binding in sausages and hams, reducing purge loss by up to 25%, as per USDA data. In baking, it acts as a dough conditioner, improving volume and texture. Animal feed formulations benefit from its phosphorus source, promoting bone health and feed efficiency – vital for USA poultry and swine operations facing rising corn costs.
Beyond food/feed, Disodium Phosphate Heptahydrate is used in detergents as a builder to soften water and boost cleaning efficacy, replacing harsher phosphates amid environmental regs. In pharmaceuticals, it's a buffering agent in IV solutions; water treatment employs it for boiler corrosion control.
At Shijiazhuang Standard IMP&EXP, we produce Disodium Phosphate Heptahydrate via advanced crystallization from high-purity phosphoric acid and soda ash, ensuring low heavy metals (<10ppm Pb, <3ppm As). Our two fermentation departments handle upstream materials, guaranteeing traceability. Export volume: 5000MT/year to USA markets.
Compared to competitors relying on fragmented China's supply chain, our integrated factory cuts costs by 30%. Purity tests via ICP-MS exceed FCC/USP monographs. Shelf life: 24 months in 25kg PE bags. Ready to optimize your supply chain? Request a sample now.
Physically, Disodium Phosphate Heptahydrate appears as colorless or white crystals, odorless, with density 1.68g/cm³. It loses 5 waters at 100°C, fully dehydrates at 250°C. Solubility increases with temperature: 5g/100ml at 0°C, 32g at 100°C. This hygroscopic nature suits instant dissolution in formulations.
Regulatory compliance for USA: GRAS status (21 CFR 182.6770), meets FCC, USP-NF. No ADI limit per JECFA. In feed, FDA limits phosphorus to prevent runoff – our low-impurity grade complies fully.
Case: A USA dairy giant switched to our DSP Heptahydrate, slashing import costs 28% while boosting product shelf life 40%. Technical data confirms zero microbial contamination.
