Polyoxymethylene Urea

Polyoxymethylene urea is a synthetic polymer derived from the reaction of urea and formaldehyde. It functions primarily as a bulking agent in cosmetic formulations, meaning it adds volume and body to products without contributing significant active skincare benefits.This ingredient is used to modify the texture, consistency and stability of creams, lotions and other topical products. It helps create a desired sensory experience and can improve how a formula spreads or adheres to the skin.

Polyoxymethylene urea works as an inert bulking agent by increasing the overall volume of a formula without participating in chemical reactions on the skin. It modifies how the product feels during application and how it behaves once applied.The polymer's structure allows it to interact with other formula components to improve consistency and shelf stability, rather than targeting specific skin concerns or penetrating the skin barrier.

Products containing polyoxymethylene urea should be used as directed on the packaging. Application frequency depends on the specific product formulation rather than the ingredient itself. Apply with clean hands or a spatula to avoid introducing bacteria, and integrate into your routine based on whether the product is a cleanser, treatment or moisturiser.

Polyoxymethylene urea is generally recognised as safe in cosmetic formulations. Those with sensitive skin or known sensitivities to formaldehyde-derived ingredients should patch-test or consult a dermatologist before use.
