Key Properties
Sodium benzoate (extra pure) is a sodium salt of benzoic acid, widely recognized for its effectiveness as a food and cosmetic preservative. It is commonly used in various industries due to its ability to inhibit the growth of mold, yeast, and some bacteria, thereby extending the shelf life of products. With a purity of 99%, this grade of sodium benzoate is suitable for applications requiring high-quality standards, including food, cosmetics, and pharmaceuticals. Its chemical stability and low toxicity make it a preferred choice in formulations where safety and efficacy are paramount.
Also known as Benzoate of soda, Sodium benzenecarboxylate.
