• Pharmaceuticals: alkalizing agent in oral solutions, effervescent tablets, and electrolyte formulations
• Personal care: buffer for creams, lotions, and oral hygiene products
• Processed cheese and meat: sequestrant that improves texture and prevents syneresis
• It functions as a pH buffer, acidity regulator, and stabilizer in finished formulations.

Good to know: It extends shelf life by chelating metal ions that would otherwise accelerate oxidation. It is essential where potassium supplementation and pH control are required simultaneously.
