Polyoxymethylene Glycol Urea

Polyoxymethylene glycol urea is a synthetic preservative commonly used in cosmetic and skincare formulations. It works by releasing formaldehyde in a controlled manner, which provides antimicrobial protection without requiring high concentrations of formaldehyde itself. This mechanism allows formulators to preserve products effectively whilst minimising exposure to free formaldehyde.As a preservative system, its primary role is to prevent the growth of bacteria, fungi and other microorganisms that could otherwise compromise product safety and stability over time. It is typically used in lea…

Polyoxymethylene glycol urea is a condensation product that releases formaldehyde gradually within a skincare formulation. This controlled release mechanism provides antimicrobial activity at relatively low concentrations, preventing the proliferation of bacteria and fungi that could otherwise cause product spoilage or pose hygiene risks.Because the formaldehyde release is regulated by the formulation's pH and water content, the ingredient functions as a gentle preservative system rather than introducing high levels of free formaldehyde directly into the product.

Polyoxymethylene glycol urea is a preservative system present in finished products; it is not an ingredient you would apply separately or adjust the frequency of. Simply use the product as directed by the manufacturer. If you notice any signs of product degradation such as separation, discolouration or unusual odour, discontinue use and obtain a fresh product.

Polyoxymethylene glycol urea is generally well-tolerated and recognised as safe by cosmetic regulatory bodies when used at appropriate concentrations. Because it releases formaldehyde in a controlled manner, exposure is considered minimal in finished products.
