Potassium Benzoate

Product Overview

Potassium Benzoate is the potassium salt of benzoic acid, recognized globally as a safe and effective preservative agent. With the CAS number 582-25-2, this compound serves as a critical ingredient across multiple industries, including food processing, pharmaceutical manufacturing, and cosmetic formulation. Our facility produces high-purity grades that meet stringent international quality standards, ensuring reliability for downstream applications where microbial stability is paramount.

As a white crystalline powder, Potassium Benzoate offers superior solubility in water compared to its acid counterpart, making it an ideal choice for liquid formulations. It functions primarily by converting to benzoic acid in acidic environments, thereby inhibiting the growth of mold, yeast, and bacteria. This mechanism ensures extended shelf life and product safety for consumers.

Key Chemical Properties

Understanding the physicochemical profile of Potassium Benzoate is essential for optimal formulation. The compound exhibits a molecular formula of C7H5KO2 and a molecular weight of approximately 160.21 g/mol. It is characterized by high stability under normal storage conditions and maintains efficacy across a wide pH range, particularly in acidic solutions below pH 4.5.

• High water solubility facilitates easy integration into aqueous systems.
• Thermal stability allows for processing under elevated temperatures.
• Low toxicity profile supports use in sensitive consumer applications.
• Compatible with a wide range of surfactants and emulsifiers.

Industrial Applications

In the cosmetic industry, Potassium Benzoate is valued as a robust antimicrobial agent that protects creams, lotions, and liquid cleansers from contamination. It acts as a drop-in replacement for less soluble preservatives, enhancing formulation flexibility. In the food sector, it is designated as E212 and is widely utilized to preserve acidic foods such as carbonated beverages, fruit juices, and pickles. Furthermore, the pharmaceutical sector employs this compound as an excipient to maintain the integrity of liquid medications and syrups.

Quality Specifications

Our manufacturing process adheres to rigorous quality control protocols. Each batch undergoes comprehensive testing to verify purity, moisture content, and chemical identity. The following table outlines the typical specification profile for our premium grade Potassium Benzoate:

Storage and Handling

To maintain optimal quality, Potassium Benzoate should be stored in a cool, dry, and well-ventilated area. Containers must be kept tightly closed to prevent moisture absorption, which could affect flowability and concentration. When handling, standard industrial hygiene practices should be followed, including the use of protective gloves and eyewear to prevent irritation. Proper storage ensures the product remains stable and effective throughout its shelf life, supporting consistent performance in your manufacturing processes.
