Sodium Benzoate

General Description
Sodium Benzoate is a widely established, broad-spectrum preservative utilized extensively across the food, personal care, and pharmaceutical industries. It serves as a primary defense agent against microbial proliferation, ensuring product integrity and preventing spoilage.

Mechanisms of Action

• pH-Dependent Antimicrobial Activity:
  Exhibits optimal biological activity in acidic environments (specifically pH 2.5 - 4.0). In these conditions, the undissociated benzoic acid penetrates microbial cell membranes, disrupting permeability and inhibiting essential metabolic enzymes to effectively block growth.

• Targeted Inhibition:
  Delivers precise inhibition of common pathogenic microorganisms, including bacteria, molds, and yeasts. It achieves an inhibition rate exceeding 90% against core spoilage organisms at low concentrations.

Key Benefits

• Synergistic Efficacy:
  Demonstrates excellent compatibility when compounded with other preservatives such as Potassium Sorbate or Sodium Dehydroacetate. This synergy broadens the antimicrobial spectrum and allows for a reduction in total preservative dosage while enhancing overall efficacy.

• Safety & Metabolism:
  Possesses a high safety profile when used within regulatory limits. Upon ingestion/absorption, it is metabolized into hippuric acid and excreted via the renal system without bioaccumulation. It is recognized by major global regulatory authorities.

• Physical Stability:
  Exhibits superior thermal stability, making it suitable for high-temperature processing workflows without degradation or adverse reactions with other formulation components.

Applications & Compatibility

• Target Industries: Food & Beverage, Personal Care (Skincare, Rinse-off products), and Pharmaceuticals.

• Formulation Suitability: Ideal for acidic formulations, including juices, carbonated drinks, acidic skincare toners, and cleansers.

• Primary Functions: Broad-Spectrum Preservation, Anti-Spoilage, Shelf-Life Extension.
