IUPAC Name: 1-[(4S)-3-(hydroxymethyl)-2,5-dioxoimidazolidin-4-yl]-3-[[[(4R)-3-(hydroxymethyl)-2,5-dioxoimidazolidin-4-yl]carbamoylamino]methyl]urea    

Uses

With parabens, Imidurea (CAS NO.39236-46-9) provides a broad spectrum of activity against bacteria, yeast, and mold. It has made the Germall 115-paraben combination one of the most widely used cosmetic reservative systems in the world.

Production

  Imidurea can be produced by the chemical reaction of allantoin and formaldehyde in the presence of sodium hydroxide solution and heat. The reaction mixture is then neutralized with hydrochloric acid and evaporated.
