Description
Imidazolidinyl urea (CAS 39236-46-9) is a synthetic antimicrobial preservative used in cosmetic and pharmaceutical formulations. It is commercially available under trade names including Germall 115, Abiol, Biopure 100, and Imidurea. It carries no E-code designation and is classified under heterocyclic compounds.
In personal care formulations such as lotions, shampoos, and creams, imidazolidinyl urea functions by releasing formaldehyde at controlled levels, disrupting microbial cell function and inhibiting bacterial and fungal growth. It is frequently paired with parabens or other preservatives to achieve broad-spectrum protection across a wider pH range.
This material is supplied as a solid and is subject to REACH registration requirements within the EU. Formulators should reference current Cosmetics Regulation (EC) No 1223/2009 Annex V limits when incorporating it into finished products. It is classified under HS code 29332990 for import and export purposes.
