Commercial Applications
Processed Cheese and Cheese Products
Dipotassium phosphate serves as an emulsifying salt in processed cheese formulations, helping stabilize fat and water distribution and maintain a uniform texture.
Powdered Beverage Mixes
Provides potassium and phosphate in selected powdered beverage formulations, where phosphate salts help regulate acidity and support formulation stability.
Food Processing and Ingredient Blends
Used in food ingredient systems requiring phosphate-based buffering to help control pH during processing and maintain consistent product characteristics.
Industrial and Laboratory Buffer Solutions
Dipotassium phosphate is used to prepare phosphate buffer solutions for laboratory analysis, biochemical procedures and industrial processes requiring controlled pH conditions.
Quality Assurance
Quality review focuses on product identity, assay, pH, moisture-related testing, insoluble matter and relevant impurities. Batch-level documentation supports incoming inspection and supplier qualification.
Jiangsu Kolod's company-level laboratory resources include ICP-OES, ion chromatography and atomic fluorescence spectrometry. Its quality procedures cover raw material inspection, production process control, laboratory analysis, finished-product inspection and batch traceability.
Purchasing documentation
• TDS: Technical specifications and physical properties.
• COA: Batch-specific analytical results.
• SDS: Product handling, storage and safety information.
• Export documents: Commercial invoice, packing list and shipping paperwork.
Packaging and Storage
The standard export package is a 25 kg bag with a polyethylene inner liner and woven outer bag. The inner liner helps reduce moisture exposure, while the outer bag protects the product during routine warehouse handling and transport.
Dipotassium Phosphate Trihydrate is hygroscopic and deliquescent. Store in a dry, well-ventilated warehouse, keep bags sealed and reseal opened packaging promptly. Protect the material from humid air during sampling, weighing and transfer.
