Urea, also known as carbamide, has a chemical formula of CH4N2O or CO(NH2)2. It is a white crystal, tasteless and odorless, easily soluble in water, ethanol and benzene, and slightly soluble in ether and chloroform. Urea is one of the simplest organic compounds and the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish. It can be used as fertilizer, animal feed, explosives, glue stabilizer and chemical raw materials. Because this substance is contained in human urine, it is named urea. As a neutral fertilizer, urea is suitable for all kinds of soils and plants. It is easy to store, easy to use, and has little destructive effect on the soil. It is a chemical nitrogen fertilizer with a large usage. Urea contains 46% nitrogen (N), which is the highest nitrogen content among solid nitrogen fertilizers. Urea is synthesized industrially with ammonia and carbon dioxide under certain conditions.

Product application

Medical Field

Dermatologists use certain urea-containing agents to increase skin moisture. The occlusive dressings used on non-surgically removed nails contain 40% urea.

Agriculture

Urea is suitable for use as base fertilizer and topdressing, and is sometimes used as seed fertilizer. Urea is in a molecular state before conversion and cannot be adsorbed by the soil, so it must be prevented from being lost with water; the ammonia formed after conversion is also volatile, so urea must be applied deep into the soil.

Cosmetic application

Urea is a very useful moisturizing ingredient that exists in the stratum corneum of the skin and is the main component of the skin's natural moisturizing factor NMF.
