Polyethylene Wax
What is Polyethylene Wax?
Polyethylene Wax is a synthetic polymer derived from ethylene monomers, commonly used in skincare formulations as an emollient, thickener, and viscosity-increasing agent. It provides a smooth, non-greasy texture to products like lipsticks, creams, and foundations by forming a protective barrier on the skin that helps retain moisture and enhance product spreadability. In cosmetics, it is valued for its stability, high melting point, and ability to improve the overall sensory feel without adding tackiness.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Bulking Agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Binding
Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.
Skin protecting
Forms a barrier to protect skin from external irritants.
Slip modifier
Improves the spreadability and glide of products on skin.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
Opacifying agent
Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.
