Polymethyl Methacrylate Edma
What is Polymethyl Methacrylate Edma?
Polymethyl Methacrylate EDMA is a synthetic polymer copolymer derived from methyl methacrylate and ethylene dimethacrylate, commonly used in skincare as a film-forming agent and texture enhancer. It creates a smooth, soft-focus effect on the skin by scattering light and filling in fine lines, often appearing as microbeads or microspheres in products like primers and moisturizers. This ingredient is prized for its inert nature and ability to improve product spreadability without penetrating the skin.
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.
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.
