Synthetic urea is created from synthetic ammonia and carbon dioxide and can be produced as a liquid or a solid. Approximately 1 million pounds of urea are manufactured in the United States alone each year, most of it used in fertilizers. Because the nitrogen in urea makes it water soluble, it is highly desired in this application. Urea is also used in commercial and industrial applications to produce some kinds of plastics, animal feed, glues, toilet bowl cleaners, dish washing machine detergents, hair coloring products, pesticides and fungicides. Medicinally, synthetic urea is used in dermatological products that re-hydrate the skin, and diuretics.
