Sodium Benzoate is a commonly used preservative in cosmetics and personal care products. It is the sodium salt of benzoic acid, a naturally occurring substance found in fruits like cranberries, plums, and apples. Sodium benzoate appears as a white, odorless crystalline powder or granules. Due to its antimicrobial properties, it helps prevent the growth of bacteria, fungi, and yeast, thus extending the shelf life of cosmetic products. Its natural origin and effectiveness in preservation make sodium benzoate a popular choice in various personal care products like lotions, creams, shampoos, and makeup items, ensuring their safety and longevity. The chemical formula of Sodium Benzoate is C7H5NaO2.
