What Is Dicalcium Phosphate?

Dicalcium Phosphate is the sodium salt that is derived from phosphate rock through a simple chemical reaction between sodium hydroxide (NaOH) and phosphoric acid (H3PO4)

Dicalcium Phosphate is an industrial chemical with multiple uses. The most popular uses of this chemical are in animal feeds, and fertilizers and they are often used in food industries. Dicalcium Phosphate is also known as mono-dicalcium phosphate and monocalcium phosphate.

Dicalcium is often used in the processes of making fertilizers and in foods as a preservative.

Dicalcium Phosphate uses.

There are various forms of Dicalcium Phosphate, and the usages of the chemical depend on the form. Manufacturers use Dicalcium Phosphate worldwide in a number of ways such as in the production of fertilizers, animal feeds, and in health matters.

Mono Dicalcium Phosphate 21%

Chemical application and strength:

  • It is used as a dietary supplement in foods.
  • Mono Dicalcium phosphate contains high level of calcium and phosphorous which are needed by humans and animal bodies.
  • Both calcium and phosphorous are essential in the formation of bones and healthy tissues. Therefore, it is mainly used as breakfast cereal additive, enriched flour and porridge formulation.

Animal feed additive:

  • For animals, the salt is used for making dog treats and as an additive in poultry and livestock feeds.
  • It is also found in some supplement table salts used in our houses.

Other Mono-dicalcium phosphate applications:

  • It is added in the formulation of body hygiene products to assist in removing body odour.
  • It is also added in toothpaste formulations to help reduce the formation of tartar on the surface of teeth.
  • Dicalcium phosphate acts as a polishing agent with an abrasive feel, which helps to get rid of any plagues around the teeth gum line.
  • It is also used as a depleting agent in the preparation of some tablet formulations where ingredients tend not to cake together.

Monocalcium phosphate 22%

Chemical application and strength:

  • It used as a leavening agent, by combining monohydrate and anhydrous types.
  • It releases a leavening gas from the baking soda when mixed with flour. This process results in fine giants in the resulting leavened dough for baking.

Food additive:

  • A combination of phosphorus and calcium helps in the repair of body tissues and bones. It also strengthens teeth and various body cells.
  • It is a feed additive and the one used for leavening bread is in a purer form than the industrial compound.
  • It is a feed additive for various animals’ feeds such as poultry, cattle and goat feeds.
  • It is added to the feeds to offer phosphorous and calcium that is needed in their bodies for strong bone formation.

Fertilizer Production:

  • It is used in the production of superphosphate fertilizers. In the process, a phosphate rock treated with acids to create triple superphosphate.
  • The residue from the above process is then used in the conversion of aluminum ore into aluminum metal.
  • When Sulphuric acid is used in the process, the resulting product contains phosphogypsum and is called a single Superphosphate fertilizer.

Dicalcium Phosphate 18% (DCP18)

Chemical application and strength:

  • It is used as a feed additive for poultries and livestock. It provides much-needed phosphorous and calcium mineral nutrition. As a result, DCP can help in treating diseases such as rickets, anemia, osteomalacia, paralysis, and pullorum diseases among poultry and livestock.
  • It is primarily used in layer feeds and helps in improving the digestion and weight of animals.
  • The benefits of DCP as feed for livestock and poultry are evident in the better rate of milk production and capability for laying eggs.
  • The food grade application of DCP is observed in the manufacture of toothpaste.
  • Trichloroisocyanuric acid is a general hygiene product that is used in sanitation for disinfection and cleaning. It works well in public toilets and the hotel washrooms.
  • Janitors at hospitals also use the acid for disinfection of general ward as well as utensils.
  • Farmers can use it for the preservation and cleaning of various fruits and vegetables. It can also be used on livestock, fish and silkworm.
  • The applications of DCP in food industry are also visible in its use as a leavening agent, an emulsion stabilizer, a nutritional supplement, and a dough conditioner.
  • You can also find DCP as a reliable leavening agent for different baked products.
  • It is a quality improvement ingredient or nutritional supplement for biscuits, ice cream powder, milk and cold drinks.

According to Dicalcium Phosphate’s MSDS, using Dicalcium Phosphate as an industrial product is safe because of these reasons;

  • You will be required to wear protective gloves.
  • Protect your eyes and face by wearing a face mask.
  • Protect your clothing by wearing an apron.
  • Thoroughly wash your hands after handling the chemical.

Proper storage and disposal of Dicalcium Phosphate needs to be taken into consideration in order to avoid any unwanted effects.

Dicalcium Phosphate needs to be kept in a tightly closed container and stored in a well-ventilated place.

How Is Dicalcium Phosphate Made?

In factories, Dicalcium Phosphate is made through the process of treating phosphate rock with nitric acid.

The process for the production of Dicalcium Phosphate involves three main steps which include

  • Phosphate rock digestion
  • Deflourination process
  • Neutralization process

First. Phosphate rock is digested using concentrated sulfuric acid. Additives are added to the solution to ensure fluorine is retained, and to allow for the growth of calcium sulfate crystal as well maximize dissolution of phosphate.

After the digestion process, the solution if filtered and the mother liquor is sent to the next step, which is called Deflourination.

Second. Deflourination involves the addition of sodium salt or potassium to the mother liquor to produce fluorine salt precipitate.

Third step is the neutralization process. Here, a solution containing mainly weak phosphoric acid is neutralized to produce dicalcium phosphate product, which then undergoes filtration to produce dicalcium phosphate which is then dried.

Where to Buy Dicalcium Phosphate in Bulk?

You may be able to find Dicalcium Phosphate in small quantities in your area. But if you need to buy large quantities of Dicalcium Phosphate, it is preferable to import directly from the manufacture. They can issue certificates and provide cost savings which is better that buying the chemical in small quantities locally or from a distributor.
