Benzoic Acid

Benzoic acid is an organic acid used in preservation systems and selected industrial formulations, with powder and granular grades. Discuss the required formulation, grade and documentation with REHN BIOTECH.

Grade, specification, packaging and regulatory requirements are confirmed for each order.

Source & Production

  • Benzoic Acid is an organic acid produced industrially by the oxidation of toluene or extracted from natural sources such as cranberries and prunes.
  • Our food-grade benzoic acid is manufactured under strict quality control to ensure high purity and compliance with international safety standards.

Functional Properties

  • Benzoic Acid is a broad-spectrum antimicrobial agent, especially effective under acidic conditions (pH < 4.5).
  • It inhibits the growth of mold, yeast, and certain bacteria, making it ideal for food preservation.
  • It also serves as a precursor in the synthesis of plasticizers, alkyd resins, and pharmaceuticals.

Product Grades & Characteristics
