Import Disodium Phosphate — Buy in Bulk from Supplier in China

Disodium phosphate from Sichuan Kunhua Chemical Co.Ltd. is a food-grade and industrial-grade anhydrous salt with a minimum purity of 98.0%, as confirmed by the supplier's analytical data. Its pH range of 8.5 to 10.0 makes it suitable for buffering applications in processed foods and pharmaceutical formulations. The water insolubility is controlled at a maximum of 0.1%, ensuring consistent dissolution properties in aqueous systems.

This compound is typically produced via controlled neutralization of phosphoric acid with sodium hydroxide, followed by crystallization and drying. It is commonly used in its anhydrous form, though hydrated variants exist in industry. The product is packaged in plastic-woven sacks with a polyethylene inner lining to prevent moisture absorption, which is critical for maintaining purity and flowability. Standard industry specifications for food-grade disodium phosphate include limits on heavy metals like lead and arsenic, though these are not stated in the listing.

Buyers in the food processing, pharmaceutical excipient, and personal care sectors source this material for its buffering capacity and emulsifying stability. It is frequently used in cheese analogues, baked goods, and injectable solutions. The supplier offers packaging in 25kg sacks and accepts bulk orders, but exact MOQ and lead time are not specified. Trade terms such as FOB or CIF may be available, but must be confirmed directly with the supplier.
