Science
Mechanism of Action
This ingredient operates as a cosmetic bulking agent, effectively diluting other solids or expanding product volume within formulations. Its polymeric nature allows it to serve as a microencapsulation agent, potentially housing and stabilizing other active compounds.

Stability
Polyoxymethylene Glycol Urea is a variable molecular weight polymer containing residual formaldehyde, typically found between 17 and 30 ppm. It demonstrates sensitivity to strong acids, which can induce hydrolysis, as well as to chlorine. Copolymers of Polyoxymethylene are known to be more stable in alkaline conditions than their homopolymer counterparts. Ideal formulation pH ranges for derived resins are 5-6 (acidic) and 7.5-8.5 (alkaline).

Safety
Safety Profile
The CIR Expert Panel has concluded Polyoxymethylene Glycol Urea is safe for use as a cosmetic ingredient, provided that the concentration of free formaldehyde in the final product does not exceed 0.2%. Due to insufficient data, its safety in aerosolized products has not been established and is therefore not recommended. Clinical studies indicate a low potential for irritation or sensitization.
