Description

Potassium Benzoate is the potassium salt of benzoic acid, a widely used synthetic food preservative. Its primary value lies in its effective antimicrobial action against yeasts, molds, and certain bacteria, particularly in acidic environments. This makes it a critical ingredient for manufacturers in the food and beverage, pharmaceutical, and personal care industries seeking to ensure product safety and extend shelf life. Potassium Benzoate CAS NO 582-25-2 is favored for its high solubility in water compared to other benzoate salts.

Application

• Food & Beverage Preservation: Primarily used in acidic products like carbonated soft drinks, fruit juices, pickles, and salad dressings to inhibit microbial growth.
• Pharmaceutical Formulations: Acts as a preservative in liquid medications, syrups, and topical preparations to maintain sterility.
• Personal Care Products: Incorporated into cosmetics, creams, and oral care items (like mouthwash) as an antimicrobial agent.
• Industrial Applications: Used as a corrosion inhibitor in some antifreeze and coolant formulations.
• Tobacco Industry: Employed in the processing of certain tobacco products.
• Animal Feed Additive: Sometimes used as a preservative in wet feed to prevent spoilage.

Quality Control

Our Potassium Benzoate is manufactured under strict quality management systems. We offer grades compliant with major international standards, including FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia), ensuring suitability for food, pharmaceutical, and industrial applications. Every batch undergoes rigorous analytical testing. Certificates of Analysis (COA) documenting purity, identity, and safety parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption. Keep away from strong acids.
