Potassium benzoate, with the chemical formula C₇H₅KO₂ and CAS number 582 - 25 - 2, is a potassium salt of benzoic acid. It is a white granular or crystalline powder, odorless or with a slight characteristic odor. The product we offer is of high - quality, meeting strict industry standards.
It has a molecular weight of approximately 160.22 g/mol. In terms of solubility, it is highly soluble in water, making it easy to incorporate into various aqueous solutions. The melting point of potassium benzoate is around 300°C. It is stable under normal storage conditions but should be kept away from strong oxidizing agents.
Food and Beverage Industry: Potassium benzoate is widely used as a preservative in the food and beverage industry. It helps to prevent the growth of mold, yeast, and bacteria, thus extending the shelf - life of products. It is commonly used in fruit juices, soft drinks, pickles, and jams. For example, in acidic fruit juices, it can effectively inhibit the growth of spoilage microorganisms, maintaining the quality and flavor of the juice over time.
Pharmaceutical Industry: In the pharmaceutical field, it can be used as an excipient in some formulations. It may also have certain antibacterial properties that can contribute to the overall stability and safety of pharmaceutical products.
Personal Care Products: Some personal care products, such as shampoos, lotions, and creams, use potassium benzoate as a preservative. It helps to keep these products free from microbial contamination, ensuring their safety and efficacy during use.
When using potassium benzoate in food and beverage applications, it should be added according to the relevant regulatory limits. In general, the addition amount is usually within 0.05% - 0.1% of the total product weight. First, dissolve the required amount of potassium benzoate in a small amount of water to form a concentrated solution. Then, slowly add this solution to the main product under stirring to ensure uniform distribution.
In pharmaceutical and personal care product manufacturing, the usage amount and process may vary depending on the specific formulation and requirements. It is recommended to conduct small - scale tests first to determine the optimal dosage. The product should be added at an appropriate stage of the manufacturing process to ensure its effectiveness.
Case 1: A fruit juice company was facing the problem of short shelf - life and microbial spoilage in their products. They decided to use our high - quality potassium benzoate. By adding 0.08% of potassium benzoate to their orange juice, they were able to extend the shelf - life from 1 week to 3 weeks at room temperature. The juice maintained its original color, flavor, and nutritional value, and there was no significant growth of mold or yeast during this period.
Case 2: A cosmetics manufacturer was looking for a safe and effective preservative for their new lotion product. They incorporated potassium benzoate into the formulation at a concentration of 0.06%. After conducting stability tests, they found that the lotion remained free from microbial contamination for more than 6 months. The product's texture and appearance also remained unchanged, indicating the excellent preservative effect of potassium benzoate.
