The Power of Phosphoric Acid: Industrial and Food-Grade Applications

Phosphoric acid is a versatile and powerful chemical that is widely used in various industries. In this comprehensive guide, we will explore the industrial and food-grade applications of phosphoric acid and its different concentrations available at Alliance Chemical.

1. Industrial Applications of Phosphoric Acid

Phosphoric acid is a popular choice for a wide range of industrial applications, from metal treatment to water treatment and beyond.

Metal Treatment and Rust Removal

One of the most common industrial uses of phosphoric acid is in metal treatment and rust removal. The 85% ACS grade phosphoric acid is a popular choice for these applications. It effectively cleans metal surfaces, removes rust, and provides a protective coating to prevent further corrosion. This is particularly useful in industries such as automotive, aerospace, and construction.

Water Treatment

Phosphoric acid is used as a pH adjuster in water treatment processes, making it suitable for use in industrial wastewater treatment plants. The 75% concentration of phosphoric acid is often used for this purpose. It helps maintain the pH balance and prevent the formation of scale in water treatment systems.

Fertilizer Production

Phosphoric acid is a key ingredient in the production of phosphate fertilizers, which are essential for promoting healthy plant growth. It is typically used in the production of monoammonium phosphate (MAP) and diammonium phosphate (DAP) fertilizers. The 85% concentration of phosphoric acid is commonly used in fertilizer production.

Cleaning and Sanitizing

Phosphoric acid is a powerful cleaning agent that can remove tough stains, mineral deposits, and organic matter from various surfaces. It is used in industrial cleaning solutions and sanitizers to effectively clean equipment and facilities. The 85% ACS grade phosphoric acid is ideal for this purpose.

2. Food-Grade Applications of Phosphoric Acid

Phosphoric acid also has a range of food-grade applications, making it an important ingredient in the food and beverage industry.

Acidulant in Beverages

One of the most common uses of phosphoric acid in the food industry is as an acidulant in beverages, such as carbonated soft drinks. The 85% food-grade phosphoric acid is used to provide a tangy flavor and help preserve the shelf life of these beverages.

Food Processing

Phosphoric acid is used as a processing aid in various food products, such as cheese, meat, and seafood. It helps to control the pH level, extend shelf life, and improve the texture of these products. The 85% food-grade phosphoric acid is suitable for these applications.

Flavor Enhancer and Emulsifier

Phosphoric acid is also used as a flavor enhancer and emulsifier in food products, such as dressings, sauces, and confectionery items. The 85% food-grade phosphoric acid is ideal for these applications, as it helps to provide a tangy flavor and improve the stability of these products.

3. Choosing the Right Phosphoric Acid Concentration

It is important to select the appropriate concentration of phosphoric acid for your specific application. Alliance Chemical offers a range of phosphoric acid concentrations to suit various industrial and food-grade applications.

85% Food-Grade Phosphoric Acid

The 85% food-grade phosphoric acid is ideal for use in the food and beverage industry. Its high purity and compliance with food safety regulations make it suitable for applications such as acidulants in beverages, food processing, and flavor enhancement.

85% ACS Grade Phosphoric Acid

The 85% ACS grade phosphoric acid is a popular choice for various industrial applications, including metal treatment, rust removal, and cleaning and sanitizing. Its high purity and compliance with American Chemical Society (ACS) specifications make it a reliable choice for these uses.

75% Phosphoric Acid

The 75% concentration of phosphoric acid is often used in water treatment applications. It is an effective pH adjuster, helping to maintain the correct pH balance and prevent scale formation in water treatment systems.

4. Storage and Handling of Phosphoric Acid

Proper storage and handling of phosphoric acid are essential to ensure safety and maintain the quality of the product. Here are some guidelines for storing and handling phosphoric acid:


Phosphoric acid should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. It should be kept in its original, tightly sealed container and placed on a spill containment pallet to prevent leaks or spills.


When handling phosphoric acid, it is important to wear appropriate personal protective equipment (PPE), such as chemical-resistant gloves, safety goggles, and a face shield. Always follow the safety precautions listed on the product’s safety data sheet (SDS).


Dispose of phosphoric acid according to local, state, and federal regulations. Consult with a qualified waste disposal service provider to ensure proper disposal procedures are followed.
