Ammonium Chloride is one of the most widely used chemicals on the market today. The white crystalline salt is used in pyrotechnics, metalwork, medicine, and for a variety of applications in the food industry. Ammonium chloride is also found in hundreds of personal care products that we use every day.

Ammonium Chloride is mainly used as a nitrogen source in fertilizers, mostly for rice and wheat crops in Asia. It is also an ingredient in fireworks, safety matches and contact explosives.

Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized, or soldered. It is an expectorant in cough medicine and as a systemic acidifying agent in the treatment of severe metabolic alkalosis.

In the food industry, ammonium chloride is used as a food additive and yeast nutrient in the making of bread. It is a feed supplement for cattle and an ingredient in nutritive media for yeasts and many microorganisms. It is used as a flavoring agent in licorice.

In several countries, ammonium chloride, known as sal ammoniac, is used as food additive under the E number E510.

In medicine, Ammonium chloride is used as an expectorant in cough medicine. Its expectorant action is caused by irritative action on the bronchial mucosa. This causes the production of excess respiratory tract fluid which presumably is easier to cough up. Ammonium salts are an irritant to the gastric mucosa and may induce nausea and vomiting.

Ammonium chloride is used as a systemic acidifying agent in treatment of severe metabolic alkalosis, in oral acid loading test to diagnose distal renal tubular acidosis, to maintain the urine at an acid pH in the treatment of some urinary-tract disorders.

Ammonium chloride can be found in shampoo, hair color and bleach, body wash and cleanser, facial cleanser, conditioner, hand dishwashing detergent, as well as in bath oils and salts.

An important use of ammonium chloride is as electrolyte in dry cell batteries where it is used because it is an ionic compound.

Ammonium chloride is also used in etching in the manufacture of printed circuits, as a fire extinguisher, an explosive in mineral winning and as a curing agent in formaldehyde-based adhesives.

Other uses include Ammonium chloride is used in a ~5% aqueous solution to work on oil wells with clay swelling problems. In the glue that bonds plywood, and in cleaning products. In hair shampoo, it is used as a thickening agent in ammonium-based surfactant systems, such as ammonium lauryl sulfate. Ammonium chloride is used in the textile and leather industry in dyeing, tanning, textile printing and to luster cotton.
