Detergents
Sodium Benzoate
Formula:
C₆H₅COONa
GOST/CAS:
CAS 532-32-1
Sodium benzoate (a highly effective biocidal component and broad-spectrum preservative) is a high-purity organic compound that serves as a key agent for protecting liquid and paste-like household and industrial chemical products from microbial contamination. The product comes in the form of a white crystalline powder or granules, which are highly soluble in water. Due to its ability to effectively suppress the activity of yeasts, molds, and various bacteria, sodium benzoate is an indispensable component for extending shelf life and maintaining the formulation stability of finished products.
Applications
Liquid Detergents: Used as a primary preservative in the production of liquid soaps, shower gels, shampoos, and bubble baths. It provides reliable protection for rinse-off products in high-humidity bathroom environments.
Household Cleaning Products: Incorporated into the formulations of dishwashing liquids, liquid laundry detergents, fabric softeners, and glass cleaners. It prevents souring, discoloration, and loss of viscosity in the finished product.
Car Care and Auto Cosmetics: Included in car shampoos, windshield washer fluids (including winter formulas), and active foams for car washes. It preserves the stability of surfactant systems during long-term storage.
Industrial Cleaning: Utilized in concentrated machinery cleaners, disinfecting solutions, and floor detergents within the industrial and HoReCa segments to eliminate bio-contamination of bulk containers.
Key Advantages
High Antifungal Activity: Effectively blocks the growth of mold and yeast cultures, which are the most common contaminants in aqueous surfactant solutions.
Stability and Compatibility: Blends perfectly with anionic, non-ionic, and amphoteric surfactants. It exhibits maximum efficacy in slightly acidic environments (pH 4.0 to 5.5).
Protection Against Formula Separation: Prevents the degradation of polymer thickeners and organic components by bacteria, thereby preserving the product's premium appearance and viscosity.
Safety and Eco-Friendliness: The product is biodegradable, non-toxic at working concentrations, and approved for use in both rinse-off and leave-on cosmetics as well as green household chemistry.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses in tightly sealed original packaging, away from heat sources and moisture.
- The product is hygroscopic. Avoid damaging the packaging to prevent caking of the powder.
- Protect from direct sunlight.
- Transportation is permitted by all types of covered transport, subject to temperature control. The material is not classified as a dangerous good (no ADR/hazardous cargo classification applies).
- Shelf life — 2 years from the date of manufacture.
