In mammals, urea is also a waste product of digested
protein normally filtered out by the
kidneys and excreted from the body in urine.
The main commercial use of urea is as a fertilizer but it has many other
industrial uses. For instance, it can serve as the raw material for the
manufacture of other chemicals, and as an ingredient in cosmetics.
