Applications of Potassium Carbonate (CAS No. 584-08-7)

Biopharmaceutical Applications

Our Potassium Carbonate (CAS 584-08-7) is featured by high solubility, making it an ideal choice for biopharmaceutical applications:

Buffering agent: Due to its good buffering capacity in the slightly alkaline pH range, it is mainly used in the biopharmaceutical industry as a buffer and pH regulator, helping to maintain pH stability. This is essential in biopharmaceutical formulations and cell cultures for maintaining the stability and efficacy of biological therapeutics such as antibodies and enzymes. It is also particularly useful in growth media and injectable solutions, where pH control is critical to ensuring optimal conditions. By stabilizing the pH, Potassium Carbonate ensures that the quality and efficacy of biopharmaceutical products are maintained throughout their manufacture and use.

Pharmaceutical Applications

In the pharmaceutical sector, Potassium Carbonate is a versatile excipient and pH modifier used in oral, topical, and parenteral formulations.
It ensures product stability, enhances solubility of active ingredients, and supports controlled-release formulations.

Common applications include:

Effervescent tablets and granules, as a source of alkalinity and CO₂ generation.
Syrups and oral solutions, where it adjusts and stabilizes pH.
Active ingredient processing, acting as a mild alkaline agent for neutralization or buffering.

Food Applications

Potassium Carbonate is a versatile food additive (E number 501) widely applied as an acidity regulator, alkali, and leavening agent. It plays a crucial role in bakery and confectionery, while also contributing to flavor enhancement and product shelf life.

Typical food applications include:

Cocoa processing: Balances acidity and promotes deeper flavor development in chocolate and cocoa-based products.
Bakery products: Serves as a leavening agent in traditional recipes such as gingerbread and honey cake, improving texture and rise.
Beverages: Helps maintain pH stability in ready-to-drink (RTD) coffee and other beverages, ensuring consistent taste and quality.
