Sodium Benzoate
Formula:
C7H5NaO2
GOST/CAS:
ГОСТ 32777-2014 / CAS 532-32-1
Sodium benzoate (a highly effective preservative, the sodium salt of benzoic acid) is a specialized chemical component acting as a key agent to inhibit the activity of yeast, mold fungi, and certain types of bacteria in acidic environments. The product appears as a white crystalline powder or granules, highly soluble in water. Due to its outstanding capacity to extend shelf life and preserve the organoleptic properties of products, sodium benzoate is indispensable in the food industry, beverage production, as well as cosmetic and pharmaceutical sectors.
Applications
Beverage Production: Used as a primary preservative in the production of non-alcoholic carbonated and juice-containing drinks, syrups, and kvass. It ensures excellent microbiological stability during storage.
Food Industry: Applied in the production of fruit and berry semi-finished goods, sauces, mayonnaises, ketchups, marinades, fish preserves, and caviar. It prevents spoilage and blocks the growth of pathogenic flora.
Cosmetics & Personal Care: Incorporated into the formulations of shampoos, shower gels, toothpastes, and conditioners to prevent secondary microbial contamination during consumer use.
Pharmaceuticals & Tobacco Industry: Utilized as a preservative in cough syrups and liquid dosage forms, as well as to prevent molding in raw tobacco leaves and sauced tobacco products.
Key Advantages
High Antimicrobial Activity: Effectively blocks the enzyme systems of yeast and molds, significantly slowing down fermentation and spoilage processes even at minimal dosage levels.
Stability & Solubility: Retains its performance properties across a wide temperature range. It features excellent water solubility, ensuring uniform distribution throughout the entire volume of the raw material.
Organoleptic Neutrality: At recommended dosages, it does not alter the taste, color, clarity, or aroma of the finished product, fully maintaining its original commercial appeal.
Safety & Certification: Fully complies with international and regional quality standards for food additives (E211). It is completely safe for health when regulated dosage limits are followed.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses in tightly sealed original packaging, away from heat sources and incompatible materials (strong oxidizers and acids).
- Recommended storage temperature range: from +5 °C to +25 °C. Avoid exposure to moisture, as the product exhibits mild hygroscopicity.
- Protect from direct sunlight. Store away from food products with strong, penetrating odors.
- Transportation is permissible by all types of covered transport while maintaining temperature control regulations. The material is not classified as a dangerous good. Shelf life is 2 years from the date of manufacture.
