Potassium Carbonate Sesquihydrate

Chemical Formula: K₂CO₃·1.5H₂O
Potassium Carbonate Sesquihydrate is a white, crystalline inorganic salt that is partially hydrated and highly soluble in water. Known for its strong alkalinity and buffering capabilities, it is used across food processing, pharmaceutical, and industrial manufacturing. This form of potassium carbonate is particularly valued for applications requiring controlled moisture content and stable pH regulation.
Appearance:
White crystalline solid
Uses:
Food & Beverage Industry:
Used as a pH regulator, leavening agent, and processing aid in applications like cocoa processing, noodle production, and caramel color stabilization. Recognized under FCC for use in regulated food systems.
Pharmaceutical Applications:
Employed as a buffering agent and excipient in oral formulations. Helps maintain product stability and solubility for certain active ingredients.
Industrial Applications:
Used in soap and detergent production, water softening, and glass manufacturing. Also serves as a drying agent and a catalyst base in specialty chemical synthesis.
