Except where noted otherwise, data are given for materials in their standard state (at 25 °C (77 °F), 100 kPa)
It is used in many cosmetics, skin care products, shampoos and conditioners, as well as a wide range of products including bubble baths, baby wipes and household detergents. Diazolidinyl urea is found in the commercially available preservative Germaben.
Commercial diazolidinyl urea is a mixture of different formaldehyde addition products including polymers.
Diazolidinyl urea is 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:
Diazolidinyl urea was poorly characterized until recently and still has a wrong CAS structure assigned to it. New data show that the hydroxymethyl functional group of the imidazolidine ring is attached to the carbon, not the nitrogen atom:
