Sodium benzoate is a widely used food preservative that helps prevent the growth of bacteria, yeast, and fungi. It is the sodium salt of benzoic acid and is commonly found in acidic foods and beverages, such as soft drinks and pickles. Its effectiveness increases in low pH environments, making it ideal for preserving products with a pH below 7. In addition to its use in food, sodium benzoate is also found in cosmetics and personal care products. It is generally recognized as safe by regulatory agencies when used in appropriate amounts. However, some individuals may experience allergic reactions or sensitivities to this compound.
