Description
Peroxyacetic Acid (PAA) is a powerful, fast-acting oxidizing agent and disinfectant. It is highly valued for its broad-spectrum efficacy against bacteria, viruses, fungi, and spores, even at low temperatures. This makes it a critical solution for industries requiring high-level disinfection and sterilization without leaving harmful residues. Key sectors include food & beverage processing, healthcare, water treatment, and pulp & paper manufacturing.
Application
- Food & Beverage Industry: Cold sterilization and sanitization of food contact surfaces, processing equipment, pipelines, and packaging materials.
- Healthcare & Life Sciences: High-level disinfection of medical instruments, surface decontamination in pharmaceutical cleanrooms, and as a sporicide.
- Water Treatment: Effective biocide for controlling microbial growth in industrial cooling towers, process water, and wastewater systems.
- Pulp & Paper Industry: Used as a bleaching agent and for brightening mechanical pulps.
- Agriculture: Sanitization of irrigation systems and post-harvest treatment of produce to reduce microbial load.
- Dairy & Brewery: Clean-in-Place (CIP) and Sterilize-in-Place (SIP) applications for tanks, vats, and filling lines.

Quality Control
Our Peroxyacetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for concentration, stability, and purity. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, hydrogen peroxide content, and acidity. We adhere to relevant industry standards for disinfectants and can support compliance with regulations including EPA, FDA, and REACH.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from direct sunlight, heat sources, and incompatible materials such as strong reducing agents, heavy metals, and alkalis. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Due to its oxidizing nature, ensure proper segregation from flammable and combustible materials.
