Sodium Benzoate (CAS 532 - 32 - 1) is an efficient, safe, and widely - used food preservative as well as a chemical additive in other fields. It is an important preservative and additive that can inhibit the growth and reproduction of many microorganisms in food and some products. It can form stable combinations with food components and microbial enzymes, etc., to prevent food spoilage and extend the shelf - life of food. It can also be used in some pharmaceutical, cosmetic and other products to play a role in antisepsis and stability maintenance.
1.High safety：Safe within approved limits, non - toxic under normal use, eco - friendly, odorless, and no toxic by - products during functions like food preservation, suitable for food, medicine, and cosmetics.
2.Good preservation effect：Works well in acidic environments (e.g., carbonated drinks, pickled products). Inhibits yeasts, molds, and some bacteria. Effective even with weak complexes in the system and less affected by common co - existing substances.
3.Stable performance：Chemically stable under normal storage and use (suitable temp, pH). Maintains antibacterial effect throughout product shelf - life.
4.Good compatibility：Mixes well with most food ingredients, pharmaceutical excipients, and cosmetic raw materials. Rarely causes adverse reactions, preserves product quality.
5.Simple application method：Easy to add in production (powder/solution form). No complex processes, convenient for industrial use.
Sodium benzoate, an organic sodium salt, releases benzoic acid in acidic environments. The acid penetrates microbial membranes, interfering with enzymes and metabolism to inhibit growth — a pH - dependent antibacterial process.
Index
*Density (20 °C): ~1.44 g/ml (varies by purity).
*pH Range: Optimal 2.5 - 4.0 (works in wider weak - acid ranges).
*Concentration: Regulated (e.g., ~0.1% - 0.2% in food, by category).
*Odor: Odorless/slightly benzoin - like.
*Appearance: White granule/powder .
Used as a preservative in food, beverage, pharma, and cosmetics, with strict standards for safety and efficacy.
Sodium benzoate is a safe and widely - used preservative. It effectively inhibits the growth of microorganisms in food, beverages, pharmaceuticals, and cosmetics. As an important antisepsis - ensuring substance, it can act on common spoilage microbes like yeasts, molds, and some bacteria in acidic environments. It functions by releasing benzoic acid molecules that interfere with microbial enzyme activity and metabolic processes, thus achieving the goal of preventing product spoilage.
Sodium benzoate is widely used:
*Food industry: Preserves carbonated drinks, pickled veggies, juices, jams (inhibits microbes, extends shelf - life).
*Pharmaceutical industry: Preserves syrups, oral solutions (prevents bacterial/fungal contamination).
*Cosmetic industry: Maintains stability of skincare/haircare products (prevents spoilage).
*Industrial fields: Preserves coatings, inks (avoids microbe - induced deterioration).
