Description
Urea (CAS 57-13-6) is a nitrogen-containing organic compound produced synthetically from ammonia and carbon dioxide. It is also known under trade names such as Urevert, Ureophil, and Ureaphil, and carries the molecular formula CH4N2O. It carries no assigned E-code for food applications.
In personal care formulations, urea acts as a humectant by drawing moisture into the stratum corneum and disrupting hydrogen bonds in keratin, improving skin hydration at concentrations of 5–40%. In agriculture, it serves as a high-nitrogen fertiliser (46% N) classified under HS code 31021010, releasing ammonium through soil hydrolysis. It also functions as a catalyst and buffering agent in textile and resin processing.
Urea is available in technical, feed, fertiliser, and Ph.Eur.-compliant pharmaceutical grades, supplied as a white crystalline powder. It falls under REACH registration requirements within the EU. Standard packaging includes 25 kg bags and bulk quantities, with grades selected according to application purity requirements.
