Potassium carbonate sesquihydrate

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

It functions as an alkali and pH buffer across food, agricultural, pharmaceutical, and industrial applications. In food production, it adjusts dough pH in cocoa processing and acts as a leavening agent.

This compound is particularly useful in baked goods where sodium-free formulations are required. Water treatment operations use it to raise pH and reduce corrosivity in distribution systems and boiler feed water.

Agrochemical formulators incorporate it as a potassium source in fertilizer blends and as a buffering agent in crop protection product concentrates. It ensures stability and efficacy in various agricultural settings.

In coatings and adhesive systems, it controls alkalinity during resin synthesis and improves adhesion performance on specific substrates. This versatility makes it a staple in industrial chemical manufacturing.

Potassium carbonate sesquihydrate is supplied as a white crystalline powder or granule. Food-grade (FCC) and pharmaceutical-grade (USP, Ph. Eur.) specifications are available to meet regulatory requirements.

Technical grade is standard for industrial and agricultural applications where tighter purity thresholds are not required. We ensure high-quality supply chains for all grades to meet your specific production needs.
