Science
Mechanism of Action
This compound primarily operates as a binding agent, adhering components together within a formulation, and as a film former, creating a thin, protective layer upon application. As a monomer, it undergoes polymerization, contributing to product structure. Its polyethylene glycol (PEG) component may also contribute minor solvent and humectant benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that methacrylate ester monomers, a class including closely related compounds like PEG-4 Dimethacrylate, are safe for use in nail enhancement products provided skin contact is avoided due to their sensitizing potential. While general PEG diesters were deemed safe when formulated to be non-irritating, a related compound, PEG-4 diheptanoate, caused slight to moderate erythema and edema at 100% in rabbits and mild irritation at 50-100% in guinea pigs. Polyethylene glycols (PEGs) with an average of 4 moles of ethylene oxide or greater were found to be safe.
