Science
Mechanism of Action
This ingredient functions principally as a viscosity-controlling agent, enabling the creation of desired product textures and consistencies. Furthermore, similar to other polyethylene glycol (PEG) derivatives, it acts as a humectant. It draws water molecules to the skin and forms hydrogen bonds, which helps to reduce water evaporation and supports the integrity of the skin's natural barrier.

Stability
For optimal long-term stability, Methoxy polyethylene glycol-Methacrylate (mPEG-Methacrylate) should be stored at -20℃, protected from light. Lyophilized powder forms typically contain polymerization inhibitors, such as 4-Methoxyphenol or MeHQ, at concentrations around 200 ppm.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that its copolymer, Acrylates/Methoxy PEG-15 Methacrylate Copolymer, is safe for cosmetic use, provided concentrations or use limitations are respected and formulations are designed to avoid irritation. The FDA has also deemed this copolymer safe for specific, limited applications in food. However, the CIR has not assessed detailed evidence regarding skin, eye, or lung irritation for the Acrylates/Methoxy PEG-15 Methacrylate Copolymer itself.
