Sodium Benzoate is the sodium salt of benzoic acid, appearing as a white crystalline powder or granules with a slight benzoic acid odor. This widely used preservative is highly effective against yeasts, molds, and bacteria in acidic environments. With excellent water solubility and stability, it serves as a versatile antimicrobial agent in food, beverage, pharmaceutical, and personal care applications. Its mechanism involves entering microbial cells and acidifying the cytoplasm, disrupting enzymatic functions and inhibiting growth.
