Product Overview

Phosphoric Acid (H3PO4) is a critical inorganic acid with extensive applications across multiple industries, characterized by its high purity and exceptional chemical versatility. As a food-grade chemical, this 85% concentration represents a precise, meticulously refined product that meets the most stringent quality standards for industrial and nutritional processing. The acid's triprotic nature allows for multiple ionization stages, enabling complex chemical interactions and precise pH modulation in various systems.

Historically discovered in 1669 by Hennig Brand, phosphoric acid has evolved from an alchemical curiosity to a fundamental industrial chemical. Its molecular structure features three hydroxyl groups attached to a central phosphorus atom, creating remarkable reactivity and compatibility with numerous chemical processes. The food-grade classification ensures minimal impurity levels, making it particularly suitable for sensitive applications in food, beverage, and pharmaceutical manufacturing.

• Dairy Product Stabilization: In milk and cheese production, the acid helps control protein coagulation and modify mineral content, enabling precise texture and consistency control in dairy manufacturing processes.
• Pharmaceutical Formulation: Used as an excipient in tablet manufacturing, phosphoric acid helps control drug dissolution rates and provides critical pH adjustment in medication development and production.
• Water Treatment Systems: Effectively reduces alkalinity, preventing scale formation in industrial and municipal water treatment facilities by neutralizing calcium and magnesium carbonates.
• Agricultural Nutrient Management: Serves as a precise phosphorus source in liquid fertilizer formulations, supporting controlled nutrient delivery in advanced agricultural systems.

Safety Precautions

Phosphoric acid requires professional handling protocols due to its corrosive nature. Users must implement comprehensive safety measures, including using appropriate personal protective equipment such as chemical-resistant gloves, splash goggles, and acid-resistant clothing. Ensure proper ventilation and maintain exposure levels below established occupational safety thresholds.

Storage demands controlled environmental conditions, maintaining temperatures below 77°F (25°C) in well-ventilated areas. Use only food-grade compatible containers constructed from materials like high-density polyethylene (HDPE) or 316L stainless steel to prevent chemical interactions and maintain product integrity.

Emergency preparedness is critical. Install eyewash stations and safety showers near handling areas, develop comprehensive spill response protocols, and ensure all personnel receive thorough training on chemical handling, potential hazards, and appropriate emergency procedures.
