It creates a biuret in the condensation process during heating. properties Urea creates colorless crystals in the form of long, odorless needles with a melting point of approximately 133 ° C. During further heating it decomposes before reaching the boiling point. It is a hygroscopic substance, easily soluble in water. utilization In cosmetics - urea is a component of NMF (natural moisturizing factor), which gives it moisture and smoothness. Lowering its concentration in the skin makes it dry and rough. Kurzajki - urea absorbs moisture. It has been used in creams since the 1940s.
