Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Polyoxymethylene Urea, a polymer structurally related to this ingredient, is safe for cosmetic use. This safety is contingent on formulations ensuring that the concentration of free formaldehyde does not exceed 0.2%. It is strictly advised against incorporating this ingredient into aerosolized products due to the heightened potential for formaldehyde release. While initial in vitro tests noted mild skin and transient ocular irritation, robust clinical data subsequently revealed no irritation or sensitization upon application.
