Science
Mechanism of Action
While specific mechanistic data for Lithium Oxidized Polyethylene is limited, its properties are understood to closely mirror those of Oxidized Polyethylene. It forms a thin, flexible polymeric film on the skin's surface, which effectively reduces transepidermal water loss and contributes to a smooth skin feel. Additionally, its polymeric structure enhances formulation texture, prevents ingredient separation, and stabilizes oil-in-water or water-in-oil emulsions, ensuring consistent delivery of active ingredients and product integrity.

This ingredient significantly improves product consistency and acts as a binding agent, ensuring ingredients remain homogeneously distributed. Furthermore, it functions as an emulsifying agent, stabilizing both oil- and water-based components to prevent separation and maintain formula integrity over time.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Polyethylene and the broader group of polyenes, including Oxidized Polyethylene, safe for use in cosmetic and personal care products under current practices. The FDA has also approved Polyethylene for cosmetic applications. Oxidized Polyethylene is generally considered non-toxic and is unlikely to cause skin irritation or sensitivity at recommended concentrations. Specific reviews for 'Lithium Oxidized Polyethylene' by CIR or SCCS were not identified.
