Imidazolidinyl Urea
Irritancy: unknownComedogenicity: unknownPreservative
The details
Imidazolidinyl Urea is a synthetic antimicrobial preservative. It works by slowly releasing small amounts of formaldehyde to keep bacteria, yeast, and mold from growing. Just so you know, the formaldehyde released at typical use concentrations (up to 0.6% in the EU and typically 0.1-0.3% in the US) are tiny. The CIR Expert Panel has reaffirmed its safety as a cosmetic ingredient at current use concentrations in 2023. It's also not mutagenic in cell studies. However, it is a known contact sensitizer with about a 1-2% contact allergy rate. Other formaldehyde releasers include Diazolidinyl Urea or DMDM Hydantoin .
