What is Potassium Citrate

Potassium citrate is also referred to by its IUPAC name as tripotassium citrate. It is a salt resulting from citric acid and potassium. Its production is accomplished when either potassium carbonate or bicarbonate is added to a solution made of citric acid. Upon mixing, effervescence occurs. After the foaming stops, the potassium citrate mixture is filtered. Then, as a result of evaporation, the eventual salt emerges as a granular substance. In its purified state, potassium citrate is odorless, hygroscopic, salty to the taste, and contains nearly 40 percent potassium.

Uses and application of potassium citrate

Potassium citrate uses include acidulant, acne treatments, beverage mixes, beverages, body wash, buffer, cheese, chelating agent, concealer, cosmetics, detergents, dietetic foods, electroplating, emulsifier, facial cleaner, flavor enhancer, food additive, fruit juices gelatin, jellies & preserves, liquid hand soap, milk protein, mouthwash, oral care, photographic, sequesterant, urinary alkalizer.

  • Personal Care: It helps to naturally preserve cosmetics and personal care products by chelating (bonding) metals.
  • Pharmaceutical: Potassium citrate serves many medical purposes for both human and veterinary care. In human medicine, its ability to metabolize quickly and control pH levels in liquids such as blood makes it one of the ideal elements in the treatment of kidney stones, especially those that result from conditions such as renal tubular acidosis. Such a condition causes the inability of the kidneys to regulate pH levels within the body by disposing of acids from the bloodstream through urination.
  • Food and Nutrition: Potassium citrate is regularly employed as a buffering agent, flavoring agent, chelating agent, stabilizer, emulsifying salt, and antioxidant. Specifically, for food and beverage manufacturers, the ingredient is commonly used as a buffering agent for carbonated beverages — such as various sodas — to control the acidity of those beverages and, therefore, keep their pH levels within a desired range. Plus, when used as a food ingredient, potassium citrate effectively regulates the acidity of certain processed foods without the added bitterness that other salts can cause.
