Description

Tri-Potassium Phosphate Monohydrate is a highly soluble, inorganic salt that serves as a critical source of potassium and phosphate ions. This compound is valued for its strong buffering capacity and its role as a nutrient and sequestrant in various industrial and food-grade applications. It is essential for manufacturers in the food & beverage, water treatment, and industrial cleaning sectors seeking a reliable, high-purity alkali phosphate.

Application

• Food Additive (E340(iii)): Used as an emulsifier, stabilizer, and pH buffer in processed cheeses, dairy products, and meat products.
• Industrial Cleaners & Detergents: Acts as a powerful water softener, grease emulsifier, and alkalinity builder in heavy-duty cleaning formulations.
• Water Treatment: Functions as a corrosion inhibitor and scale control agent in boiler and cooling water systems.
• Fertilizer & Agricultural Solutions: Provides a highly soluble source of potassium and phosphorus in liquid fertilizer blends and nutrient solutions.
• Pharmaceutical & Cosmetic Excipient: Employed as a buffering agent and pH adjuster in certain pharmaceutical preparations and personal care products.
• Laboratory Reagent: Used in analytical chemistry and molecular biology as a buffer component in various biochemical assays.

Quality Control

Our Tri-Potassium Phosphate Monohydrate is manufactured under a strict quality management system. It is available in various grades, including Food Grade (FCC) and Technical Grade, with specifications tailored to meet the rigorous demands of each application. Every batch is tested to ensure compliance with relevant purity and safety standards. A Certificate of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent caking and degradation from atmospheric moisture.
