Cas no 582-25-2 (Potassium benzoate)

Potassium benzoate (C?H?KO?) is a white, crystalline salt derived from benzoic acid, widely used as a preservative in food, beverage, and pharmaceutical industries. Its primary function is inhibiting the growth of mold, yeast, and bacteria, particularly in acidic environments (pH < 4.5). The compound is highly soluble in water, ensuring uniform distribution in liquid formulations. Potassium benzoate is favored for its stability, low toxicity, and compatibility with other ingredients. It is often employed as an alternative to sodium benzoate for low-sodium applications. Regulatory agencies such as the FDA and EFSA approve its use within specified limits, making it a reliable choice for preservation.

Additional information on Potassium benzoate

Comprehensive Guide to Potassium Benzoate (CAS No. 582-25-2): Properties, Applications, and Safety

Potassium benzoate (CAS No. 582-25-2) is a widely used food preservative and antimicrobial agent. This white, crystalline powder is the potassium salt of benzoic acid, known for its effectiveness in inhibiting the growth of mold, yeast, and bacteria. With the increasing demand for clean-label and safe preservatives, potassium benzoate has gained attention as a preferred alternative to synthetic additives. Its E number E212 designation further highlights its regulatory approval in the food industry.

The chemical formula of potassium benzoate is C7H5KO2, and it is highly soluble in water, making it ideal for beverages, sauces, and other liquid-based products. Consumers and manufacturers alike are increasingly searching for "is potassium benzoate safe" or "potassium benzoate vs sodium benzoate," reflecting growing health-conscious trends. Studies confirm its safety within recommended limits, though debates about its interaction with vitamin C (forming benzene) remain a hot topic.

In the cosmetics industry, potassium benzoate serves as a preservative in skincare and haircare products, often listed under "preservative-free alternatives" discussions. Its mild nature compared to parabens has made it a popular choice for sensitive skin formulations. Additionally, its role in pH stabilization aligns with the rising demand for "pH-balanced products" in personal care.

From an industrial perspective, potassium benzoate (CAS 582-25-2) is also utilized in pharmaceuticals as an excipient and corrosion inhibitor. Searches like "benzoate preservatives in medicine" or "potassium benzoate shelf life" underscore its versatility. Proper storage in airtight containers away from moisture ensures its longevity, a key concern for bulk buyers.

Environmental impact is another trending focus. Potassium benzoate is biodegradable, addressing queries such as "eco-friendly food preservatives." Its low toxicity to aquatic life further supports sustainable manufacturing practices. Regulatory bodies like the FDA and EFSA have established guidelines for its use, reinforcing its global acceptance.

In summary, potassium benzoate (CAS No. 582-25-2) remains a critical ingredient across industries due to its efficacy, safety profile, and adaptability. Whether for "preserving homemade foods" or formulating "clean beauty products," its applications continue to evolve with consumer and technological advancements.
