Tripotassium citrate is the tripotassium salt of citric acid. It appears as a white, crystalline, odorless solid and is highly soluble in water. It is commonly used as a buffering agent, emulsifier, and potassium supplement in food, pharmaceuticals, and industrial applications.
🏭⚗️ Production
Tripotassium citrate is produced by neutralizing citric acid with potassium carbonate or potassium bicarbonate in aqueous solution. The resulting salt is then crystallized and dried to obtain the pure compound.
🔬 Properties
Tripotassium citrate is a white, hygroscopic crystalline powder. It is freely soluble in water, forming a neutral to slightly basic solution. It is stable under normal conditions and has a mildly saline taste. The compound provides both citrate ions and potassium ions, making it useful in formulations requiring pH adjustment or potassium supplementation.
🧪 Applications
• Food industry: Used as a buffering agent, acidity regulator, and emulsifier (E332) in processed foods and beverages.
• Pharmaceuticals: Employed to treat kidney stones and metabolic acidosis, and as a source of potassium in electrolyte solutions.
• Cosmetics and personal care: Used to regulate pH and improve formulation stability.
• Industrial uses: Applied in cleaning agents and water treatment formulations.
