Sodium benzoate powder (C₇H₅NaO2) is a highly soluble, odorless, and white crystalline powder widely used as a preservative in food, cosmetics, and pharmaceuticals. It prevents the growth of harmful bacteria, mold, and yeast, extending the shelf life of acidic products.
Key Applications
-
- Food & Beverages: Found in carbonated drinks, fruit juices, pickles, jams, and salad dressings. It is most effective in acidic environments (pH below 4.5).
- Cosmetics & Personal Care: Acts as an antimicrobial agent to keep lotions, creams, shampoos, and baby wipes safe from spoiling.
- Pharmaceuticals: Used as a preservative in medications and cough syrups.
Usage and Safety Guidelines
- Regulatory Limits: The FDA limits sodium benzoate to a maximum of 0.1% concentration by weight in foods and beverages.
- The Benzene Risk: It should never be mixed with ascorbic acid (Vitamin C) in the presence of heat or light, as this combination can form benzene, a known carcinogen.
