Some forms are available over-the-counter (OTC). Urea is reabsorbed in the inner medullary collecting ducts of the nephrons,[33] thus raising the osmolarity in the medullary interstitium surrounding the thin descending limb of the loop of Henle, which makes the water reabsorb. Increasing concentrations of urea in the range 0 to 8 molar lower the Tm by 2.25 degrees C per molar, and decreases the renaturation rate by approximately 8 percent per . Urea preparations are for external use only. Penetration: Urea supplements skin penetration of topical medication such as corticosteroids and antifungals in order to treat scaling and inflammation of the skin.

Instead of feeding carbon dioxide gas directly to the reactor with the ammonia, as in the total recycle process, the stripping process first routes the carbon dioxide through a stripper (a carbamate decomposer that operates under full system pressure and is configured to provide maximum gas-liquid contact). If you have super dry skin, you need urea. Because the urea conversion is incomplete, the product must be separated from unchanged ammonium carbamate. In early "straight-through" urea plants this was done by letting down the system pressure to atmospheric to let the carbamate decompose back to ammonia and carbon dioxide.
