Diazolidinyl urea is an Allantoin derivative, a highly effective, broad-spectrum antibacterial preservative with excellent activity against Pseudomonas species. It is non-irritating to the eyes, skin, and mucous membranes at use levels. It is also known under the trade name Germall II.
Diazolidinyl urea acts as a formaldehyde releaser. It is highly water-soluble, retaining its activity in the presence of proteins, nonionic surfactants, and most other common ingredients used in personal care formulations and hand sanitizers. It may be added directly to aqueous systems without heating.
In a hot process, Diazolidinyl urea should be introduced during the cooling stage, below 60°C, and recommended below 40°C. Because it is hygroscopic, it should be stored in tightly sealed containers when not in use.
Diazolidinyl urea is a well-studied and widely used preservative. However, due to its formaldehyde-releasing mechanism, some researchers consider it a potential carcinogen and a genotoxic agent. There are many reports of sensitization, including contact dermatitis and other allergic reactions.
