Industrial Uses of Phosphoric Acid

Are you aware that globally, enough rust eats iron and steel infrastructure every year to build a whole new Golden Gate Bridge? It is expensive to treat and manage corrosion, which makes it risky for the safety of these critical infrastructures. Yes, this is a serious issue because it involves risks to human lives and leads to an unbalanced ecology. But don’t worry! Fighting against rust is a challenge but there is science’s magic that can save all of us and that is phosphoric acid. Phosphoric acid is a transparent, odorless, phosphorus-containing solid and inorganic water-soluble substance that is easily washed away and has the chemical formula H3PO4. Phosphoric acid is an acid that is used in various industries and can impact our daily lives.  This versatile industrial chemical has various uses. In this blog, let’s discuss how phosphoric acid is shaping our society and improving our lifestyle.

Uses of phosphoric acid

Pharmaceuticals and cosmetics:

Phosphoric acid is widely applied in healthcare and beauty as well. It can be used at lower concentrations to adjust the pH of multiple types of non-prescription drugs. Additionally, it serves as a component in diverse types of dental blocks of cement as well as etching solutions used during dental operations. In cosmetic formulations, it acts as a pH regulator in various skincare products. Thus, helping to keep the skin balanced. 

Fire retardants:

Phosphoric acid is critical for fire safety due to its action as an alternative fire retardant for numerous substances. To contain fire flames, this substance can be applied to certain fabrics, polymers, or timber treatment compounds. In so doing, it aids in reducing the tendency for fire spreadability in its different forms while making sure that this does not damage the surroundings, including people’s lives or structures. 

Beverage Industry:

It serves as a flavorful agent and acidity regulator in weak form. It imparts a slight tartness to drinks, making them taste better in general. Next time you drink, make sure to know that part of the reason it tastes good is because of some science involved in creation’s fizziness. 

Food processing: 

Beyond soft drinks, the other uses of phosphoric acid are in food processing, it is a leavening agent in some bakery products, especially those designed for their elevating behavior while helping to make them rise elegantly. Additionally, phosphoric acid could be used as an ingredient in certain processed cheese varieties aimed at adjusting their acidic levels as well as enhancing their taste characteristics. At times, phosphoric acid is included in our favorite meals, thus giving some of the often-consumed dishes more taste. 

Cleaning solution:

Aside from being used for heavy-duty industrial cleaning, phosphoric acid is also applied in domestic cleaning solutions. This property is very beneficial as it can help remove rust or mineral deposits in various tile cleaners or metal polishes. In addition to this, it also aids in getting rid of stubborn stains from our homes while at the same time bringing back shine to surfaces. 

Fertilizer production:

It serves as a key ingredient in most phosphate fertilizers, it is this vital phosphorus for plants. Just like urea fertilizer, which provides nitrogen to plants to help them with nutrition deficiencies, phosphorus helps them grow healthy and beautiful. Root formation is essential to the strong and healthy growth of plants, without it, there would be a lack of production by farms, thereby leading to possible threats to food security globally. 

Rust remover:

Phosphoric acid is capable of destroying rust, which is made up of iron oxide, by converting it into another compound that can easily dissolve in water.  This gradual conversion makes structures like bridges, buildings, high-rise apartments, or even water transport vessels resistant to corrosion, ensuring they last longer without breaking down. Perhaps, you have ever stood before an airplane wondering how metallic surfaces remain so shiny, but what you didn’t know is that phosphoric acid might be used to preserve them from rusting. 

Electrolyte enhancer:

Phosphoric acid can be used for energy purposes. It can act as an electrolyte in certain types of fuel cells. Chemical energy and electrical energy transform fuel cells and phosphoric acid enhances the movement of ions in cells making them more efficient. Phosphoric acid could be one of the alternative energy sources tested for possible application in upcoming technologies if ongoing research is to be considered. 

Conclusion

Phosphorus acid may be a basic molecule, but its importance cannot be overstated. The surprising breadth of its applications can be seen from the point of view of maintaining infrastructure, food standards, and developing sustainable sources of power. Looking for a reliable source of high-quality phosphoric acid for your industrial applications?Trade Asia International is the one-stop shop for all of your industrial chemical needs.
