Expert Verdict

Residual monomer must be controlled (methacrylate monomers can sensitize); 1,4-dioxane potential from 48 EO unit PEG chain. 48 EO units (~2,100 g/mol PEG portion) makes this a relatively hydrophilic methacrylate monomer - copolymers incorporating it will have enhanced water solubility/swellability compared to shorter PEG methacrylates; synthetic origin
