Science
Mechanism of Action
This ingredient functions primarily as a film-forming agent, creating a thin, occlusive layer on the skin that significantly reduces transepidermal water loss, promoting sustained hydration and a visibly smoother complexion. Beyond its film-forming capabilities, Oxidized Polyethylene acts as a robust texture enhancer and binding agent, stabilizing emulsions and preventing phase separation. The oxidation process introduces polar carbonyl and hydroxyl groups, which greatly improve its compatibility with other polar ingredients and enhance its emulsifying and dispersing properties within complex formulations.

Stability
Oxidized Polyethylene demonstrates excellent chemical and thermal stability, withstanding exposure to both acids and alkalis, and features a broad melting point range of 87-140°C. While inherently insoluble in water, its oxidized structure, containing hydroxyl and carboxyl groups, significantly boosts its compatibility with polar resins and enhances its emulsifying and dispersing properties in various formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Polyethylene, including its oxidized form, safe for use in cosmetic and personal care products. Its large molecular size restricts significant dermal absorption, minimizing systemic exposure. It is considered non-toxic, non-irritating, non-sensitizing, and notably non-comedogenic, ensuring it does not clog pores. The US FDA has also approved its use in cosmetics and certain food-contact applications under specified conditions.
