1. Product Introduction & Main Application
Arnico’s Phosphoric Acid is a high-purity, clear, odorless liquid mineral acid, supplied in both industrial and food-grade forms. As the primary source of phosphate ions, it plays a crucial role in the production of chemical fertilizers, acts as an acidulant in carbonated soft drinks, and serves as a metal corrosion protector in the metallurgy industry.

3. Features & Benefits
-
Guaranteed Food-Grade Purity: Fully compliant with FCC and WHO standards for use in edible and potable products.
-
Unparalleled Phosphate Solubility: Forms soluble complexes with calcium and iron, preventing scale formation in irrigation systems and food processing.
-
Mild & Controlled Acidity: Possesses sufficient acid strength for industrial applications without the extraordinarily aggressive corrosivity of halogenated acids.
-
Metal Corrosion Inhibition: The ability to create a protective phosphate layer (phosphatization) on iron and steel surfaces.
4. Industrial Applications
-
Food & Beverage Industry: The acidulant (E338) in cola beverages, dairy products, and edible oils.
-
Agriculture & Fertilizer: The primary raw material for producing solid phosphate fertilizers (DAP/MAP) and liquid fertilizers.
-
Metallurgy & Metal Finishing: Phosphating car bodies and home appliances, and cleaning metal surfaces.
-
Pharmaceutical & Dental Industry: A component in dental cements and a buffering agent in pharmaceutical solutions.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): Concentrated phosphoric acid is corrosive and causes severe skin and eye burns. Its vapors are irritating at high temperatures. Complete information is available in the Arnico MSDS.
-
Storage Conditions: Store in 316L stainless steel or heavy-duty polyethylene tanks, above +21°C (to prevent crystallization), and away from alkalis and reactive metals.
-
Personal Protective Equipment (PPE): The use of a face shield, chemical goggles, butyl or neoprene rubber gloves, and acid-resistant clothing is essential when handling the product.
6. Quality Assurance & COA
Arnico provides its Phosphoric Acid with a Certificate of Analysis (COA) and a guarantee of compliance with national and international standards for the food grade, including a full heavy metal analysis.
