Description

Potassium Bitartrate is a potassium acid salt of tartaric acid, widely recognized for its role as a key leavening agent and stabilizer. This high-purity compound is essential for ensuring consistent quality and predictable performance in sensitive formulations. It is a critical ingredient for manufacturers in the food and beverage, pharmaceutical, and chemical synthesis industries, where precise acidity control and reliable sourcing are paramount.

Application

• Food & Beverage Industry: Primary use as a leavening agent (cream of tartar) in baking powders, stabilizing egg whites, and controlling acidity in wines and confectionery.
• Pharmaceuticals: Used as a mild laxative and as a precursor in the synthesis of other pharmaceutical compounds.
• Chemical Synthesis: Serves as a chiral resolving agent and a starting material for producing tartrates and other organic salts.
• Laboratory & Analytical Reagents: Employed as a buffer component and a standard in various analytical procedures.
• Cosmetics & Personal Care: Acts as a pH adjuster and a gentle exfoliant in skincare formulations.
• Cleaning Products: Utilized as a component in eco-friendly cleaning agents due to its mild acidic and chelating properties.

Quality Control

Our Potassium Bitartrate is manufactured under strict quality management systems to ensure it meets the highest standards for purity and consistency. We offer grades compliant with Food Chemical Codex (FCC) and USP monographs, suitable for food and pharmaceutical applications. Every batch is supported by a comprehensive Certificate of Analysis (COA), verifying identity, assay, and impurity profiles, available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
