diazolidinyl urea is an antiseptic and deodorizer. It is also a broadspectrum preservative against bacteria and fungi. generally, it is used in concentrations of 0.03 to 0.3 percent. It has been found that diazolidinyl urea is a stronger sensitizer than imidazolidinyl urea for people sensitive or allergic to formaldehyde. | [CAS DataBase Reference]

Diazolidinyl urea, a formaldehyde re1easer, is mainly
contained in cosmetics and toiletries, and can be found
in barrier creams. | [Definition]
ChEBI: Diazolidinylurea is an imidazolidine-2,4-dione. | [Flammability and Explosibility]
Nonflammable | [Safety]
The Cosmetic Ingredient Review Expert Panel evaluated the safety of diazolidinyl urea and found that the ingredient is safe for current uses and concentrations, and it has low eye irritation potential. However, it has not been found to be sensitive to the skin or produce phototoxic effects. It’s use is restricted to maximum concentrations of 0.5%. This limit in concentration is mostly due to mild irritation that can occur on the skin in concentrations greater that this maximum. | [storage]
