Potassium carbonate sesquihydrate

Potassium carbonate sesquihydrate (CAS 6381-79-9) is a hydrated form of potassium carbonate with a consistent, measured water content that simplifies dosing in moisture-sensitive processes.

Where is Potassium carbonate sesquihydrate used?

• Food: adjusts dough pH in cocoa processing and acts as a leavening agent
• Baked goods: sodium-free formulations
• Water treatment: raises pH and reduces corrosivity in distribution systems and boiler feed water
• Agrochemicals: potassium source in fertilizer blends and buffering agent in crop protection concentrates
• Coatings and adhesives: controls alkalinity during resin synthesis and improves adhesion on specific substrates
• It functions as an alkali and pH buffer in food, agricultural, pharmaceutical and industrial applications.

Good to know: Food-grade (FCC) and pharmaceutical-grade (USP, Ph. Eur.) specifications are available; technical grade is standard for industrial and agricultural applications where tighter purity thresholds are not required.
