Methylmethacrylate Glycol Dimethacrylate Crosspolymer
What is Methylmethacrylate Glycol Dimethacrylate Crosspolymer?
Methylmethacrylate Glycol Dimethacrylate Crosspolymer is a synthetic crosspolymer formed from methylmethacrylate and glycol dimethacrylate monomers, creating a porous, sponge-like microstructure. It functions primarily as a delivery system in skincare, encapsulating active ingredients like retinol or salicylic acid to provide controlled and sustained release, enhancing stability and efficacy while minimizing irritation. This ingredient is commonly used in oil-control and anti-aging formulations due to its oil-absorbing and mattifying properties.
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.
