POLY(METHOXY PEG-9 METHACRYLATE)
Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A water-soluble PEG-methacrylate polymer used as a film former and rheology modifier. High molecular weight makes it inert on skin; safety hinges on monomer/dioxane purity.
Function
Skin benefits
- Film-forming/rheology modifier
- Provides smooth skin-feel in formulations
- Inert at cosmetic use levels
Known concerns
- PEG fraction may carry trace ethylene oxide/1,4-dioxane if poorly purified
- High molecular weight limits skin penetration but lacks dedicated CIR opinion
- Methacrylate residual monomer must be controlled
