Technical Grade Urea is an organic compound. Urea serves an important role in the metabolism of nitrogen-containing compounds. It is a colourless, odourless solid, highly soluble in water, urea is basically non-toxic. It get Dissolved in water easily, urea is not acidic. Urea is also not alkaline. The human body uses urea in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules with a carbon dioxide molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry, animal feed, laminated boards.
T.G.Urea is non-corroding alternative to rock salt uses for manufacturing of C.P.C blue Crude, Urea formaldehyde, ingredient in hair removers, browning agent, Raw material in skin cream, moisturizers, hair conditioners, Raw material for flame-proofing agent, Raw material for tooth whitening products, Raw material in dish soap, Raw material for fermentation of sugars into ethanol, A nutrient used by plankton in ocean nourishment experiments for geoengineering purposes, Additive for extending the working temperature, As a solubility-enhancing and moisture-retaining additive to dye baths for textile dyeing or printing.
