POLYOXYMETHYLENE MELAMINE UREA.

Optional CAS 25036-13-9 / BULKING

This polymer functions as a fundamental cosmetic bulking and thickening agent, precisely adjusting the density and rheology of product formulations. Derived from urea and melamine, it contributes significantly to the desired tactile and textural properties of a product.

Summary

Bulking Thickening agent/Consistency regulator

Science

Mechanism of Action

The primary mechanism of Polyoxymethylene Melamine Urea involves reducing the overall density of cosmetic products through a swelling action. Concurrently, it acts as a consistency regulator, impacting the flow and viscosity to achieve specific product textures.

Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Polyoxymethylene Urea, a chemically related component, concluding its safety for cosmetic applications with the critical restriction that free formaldehyde concentrations must not exceed 0.2% in the final product. This limitation addresses the potential for formaldehyde release from the ingredient. While some tests indicated Polyoxymethylene Urea as a mild skin and transient ocular irritant, clinical data did not demonstrate irritation or sensitization. Its use in cosmetics and personal care products is permitted in Europe under general provisions. However, its incorporation into aerosolized products is not recommended due to insufficient safety data and the inherent risk of formaldehyde release.
