Potassium citrate monohydrate

Potassium citrate monohydrate (CAS 6100-05-6), also sold as tripotassium citrate monohydrate and listed as E332, is a potassium salt of citric acid used across food, pharmaceutical, and personal care manufacturing. It functions primarily as a pH buffer, acidity regulator, and stabilizer in finished formulations. In food and beverage production, E332 regulates acidity in soft drinks, dairy products, and processed foods.

It extends shelf life by chelating metal ions that would otherwise accelerate oxidation. Pharmaceutical manufacturers use it as an alkalizing agent in oral solutions, effervescent tablets, and electrolyte formulations. This ingredient is essential where potassium supplementation and pH control are required simultaneously. In personal care, it buffers creams, lotions, and oral hygiene products to maintain formulation stability.

It also functions as a sequestrant in processed cheese and meat products, improving texture and preventing syneresis. Potassium citrate monohydrate is supplied as a white crystalline powder or granules. Standard grades include FCC, USP, BP, and Ph. Eur., covering both food and pharmaceutical procurement requirements for global manufacturers and distributors.

Packaging typically ranges from 25 kg bags to bulk quantities depending on grade and application. These standards ensure the highest purity for sensitive industrial and medical applications.
