Phosphoric acid is an extremely versatile chemical compound that plays a vital role across numerous key industries, including food and beverage, agriculture and pharmaceuticals. But finding trustworthy information on buying and properly using phosphoric acid poses a significant challenge for many people. Most common questions involve where to actually source it? What concentration grades are available? and how to handle it safely?
To address these concerns, we’ve created this inclusive phosphoric acid purchasing guide. In this guide, we will tackle the most frequently asked questions, discuss applications in major industries and provide guidance on recommended handling and best storage practices. By the end of this blog-post, you will possess the knowledge to make well-informed decisions about buying and working with phosphoric acid.
What is phosphoric acid?
Phosphoric acid is a colorless and odorless liquid. Its chemical formula is H3PO4. When used as a food additive, it goes by the E number E338. Chemically speaking, phosphoric acid molecules contain phosphorus, hydrogen, and oxygen atoms linked together.
The industrial production of food-grade phosphoric acid involves treating phosphate rock with sulfuric acid. This pulls out and concentrates the phosphoric acid present in the phosphate mineral. As an ingredient, phosphoric acid gives foods a nice tangy, sour taste. It can act as an acid regulator, chelator, stabilizer, antioxidant, flavor booster, and leavening agent.
By controlling acidity, phosphoric acid helps prevent spoilage and germs from growing. Its antioxidant effects also prevent colors from changing. Typically, foods contain 0.5-2 grams of phosphoric acid per kilogram. Soft drinks have the highest percentages, where phosphoric acid provides that tart, zingy flavor.
While an industrial chemical, food-grade phosphoric acid has many approved uses in cooking for stabilizing pH, adding punchy flavors, extracting proteins, and interacting with rising agents. This helps foods better maintain quality and freshness.

What are the common applications of phosphoric acid?
Phosphoric acid has widespread use across food and beverage, pharmaceutical, chemical, and other industries. Within food and beverages industry, it serves as an acidity regulator, antioxidant, chelating agent, and flavor enhancer. It provides a tart, sour taste and stabilizes the pH of products like soft drinks, jellies, baked goods, meats, and cheeses. For pharmaceuticals, phosphoric acid is present in toothpaste, mouthwash, and electrolyte solutions. Here, it provides minerals and aids in the prevention of tooth decay. It also assists drug synthesis and acts as a buffering agent.
Industrially, phosphoric acid removes rust, serves as an industrial cleaner, and enables conversion coatings on metals such as zinc and iron. It prevents rust by taking advantage of phosphoric acid’s ability to create a thin oxide layer. In chemical processes, it yields phosphates, esters, and phosphorus pentoxide. Detergents and cleaners contain phosphates from phosphoric acid, which improve water softening properties. Other uses include stain removal, odor control, flavoring animal feeds, and reducing water spots. Phosphoric acid is also vital for deposit coatings and electroplating processes that produce phosphorus compounds.
Is phosphoric acid safe to handle?
Phosphoric acid can corrode, so protective gear like gloves, goggles, and clothing should be worn to prevent skin and eye contact when handling it. Reading the safety data sheet (SDS) from the supplier is very important to understand proper safety protocols.
Can phosphoric acid be used in the food industry?
Phosphoric acid is utilized in foods as an acidified pH adjuster. It is found in carbonated drinks, jellies and jams, snacks, and other edibles. But, the type used in food must be food-grade phosphoric acid.
Is phosphoric acid available in different concentrations?
Yes, phosphoric acid is available in different concentrations. It usually ranges from 75% concentrated to 85% concentrated phosphoric acid. The concentration selected depends on the intended use, so picking the right grade to meet application needs is important.
Does phosphoric acid get used in making fertilizers?
Indeed, the production of phosphate-based fertilizers involves phosphoric acid as main component. It provides phosphorus in a soluble form that plants can readily absorb, promoting healthy growth and development.
Can phosphoric acid be used in the production of beverages other than soft drinks?
Yes, numerous non-soft drink beverages can benefit from the addition and flavoring of phosphoric acid. Its tangy flavor and acidity enhance ready-to-drink teas, flavored waters, sports drinks and more. Phosphoric acid also stabilizes pH, inhibiting microbial spoilage to maintain quality. And it interacts with other ingredients to extract flavors. With its pleasant sour taste and preservative effects, phosphoric acid finds wide application for formulating flavored bottled beverages beyond just sodas.
Can phosphoric acid be used in the production of pharmaceutical intermediates?
Phosphoric acid is used a lot to synthesize certain pharmaceutical intermediates and active ingredients. The phosphate group can get incorporated into drug molecules to change their activity and properties. Phosphoric acid forms phosphate esters with alcohols and amines that have medical effects and uses. It also helps drive reactions and alter other molecules through phosphorylation. Phosphoric acid provides the phosphorus needed to make organophosphate chemical compounds.
Can phosphoric acid be used in the production of personal care products?
Yup, phosphoric acid works great in certain personal care products. In toothpaste, it fights cavities and enamel breakdown. It also controls tartar buildup. For facial scrubs and chemical peels, phosphoric acid offers exfoliating properties to slough off dead skin. It can balance and adjust pH levels in shampoos and hair formulas too. In soaps and detergents, phosphoric acid contributes water softening abilities. It even acts as a preservative. So phosphoric acid gives beneficial effects like anti-cavity power, exfoliation, pH control and preservation in oral hygiene, skin and hair care goods.
What Should You Consider When Using and Storing Phosphoric Acid?
Phosphoric acid is a weak acid, but it can still pose health hazards if not handled and used carefully. For example, spills on skin or eyes can cause severe or chronic irritation. Consuming too much can also severely irritate internal organs.
So it’s advised to use proper protective gear when handling phosphoric acid. Also, stick to recommended usage amounts.
For storing phosphoric acid:
- Keep it in a cool, well-ventilated room without moisture.
- Store away from flammable stuff, metals, oxidizers, alkalis or other incompatible substances.
- You can store it in coated fiberboard or metal containers.
- Follow local government rules and standards for disposing of acidic compounds.
The secret to avoiding health and safety risks when using and storing phosphoric acid is to exercise caution. Proper handling and storage helps keep exposure risks to a minimum.
Does Phosphoric Acid Have Effects on Your Body?
It is generally accepted that moderate consumption of phosphoric acid is safe for humans. But over time, having too much phosphoric acid could cause issues. One worry is that the high phosphoric acid levels in some sodas may link to lower bone density. Too much phosphorus can interfere with the calcium absorption needed to maintain healthy bones. Bone loss mainly happens in people with generally poor nutrition.
Phosphoric acid could also interact with heart disease, especially in patients with kidney problems that reduce phosphate excretion. Consuming too much may also raise kidney stone risks. For healthy people, normal phosphoric acid intake likely poses little threat. As with any food additive, your overall diet matters most. Moderate phosphoric acid intake, as part of a balanced diet, seems unlikely to present risks. However, people with kidney or bone issues should be careful with high-phosphate foods and drinks.
