Product Overview

Phosphoric Acid 85% Food Grade (H3PO4), also known as Orthophosphoric Acid, is a high-purity, viscous liquid meeting USP-NF monograph standards. This concentrated solution serves as a critical acidulant and pH adjuster in the food and beverage industry, offering precise acidity regulation for soft drinks, dairy processing, and baking formulations.

Beyond food applications, this 85% concentration is utilized in hydroponics as a phosphorus source and in industrial cleaning for passivation and mineral deposit removal. The product features a low impurity profile with strict controls on heavy metals (Arsenic, Lead, Heavy Metals), ensuring compliance for clean-label requirements. It is available in bulk packaging ranging from 1 quart to 250-gallon totes to support both pilot testing and large-scale manufacturing.

Key Properties

  • Chemical Name: Phosphoric Acid
  • Synonyms: Orthophosphoric Acid, H3PO4
  • Concentration: 85%
  • Grade: Food Grade (USP-NF)
  • CAS Number: 7664-38-2
  • Appearance: Colorless, odorless viscous liquid
  • Specific Gravity: 1.66 – 1.70
  • Boiling Point: 158 °C
  • Heavy Metals (as Pb): ≤ 0.2 ppm (typical 0.05 ppm)
  • Arsenic (As): ≤ 0.01 ppm (typical 0.005 ppm)
  • Solubility: Miscible in water
  • Shelf Life: 24 months with proper storage

Common Applications

  • Beverage Acidulant: Provides the characteristic tartness in colas and soft drinks while inhibiting microbial growth through pH reduction.
  • pH Control: Used to adjust and buffer pH levels in cheese processing, brewing, and jams/jellies manufacturing.
  • Nutrient Source: Supplies essential phosphorus in hydroponic solutions and liquid fertilizers.
  • CIP Cleaning: Effective for removing beer stone and milk stone in dairy and brewery equipment cleaning cycles.
  • Surface Treatment: Used in metal finishing to prepare surfaces and prevent flash rusting.

Safety & Handling

Phosphoric Acid 85% is corrosive (UN 1805, Class 8). Handling requires appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves, goggles, and face shields. Store in a cool, well-ventilated area in corrosion-resistant containers (HDPE or glass). In the event of skin or eye contact, rinse immediately with copious amounts of water. Refer to the Safety Data Sheet (SDS) for detailed emergency response and disposal procedures.
