About
A very large polyethylene glycol polymer used primarily as an emulsifier and viscosity controller in cosmetic formulations.
PEG-240 is a high molecular weight polymer of ethylene oxide averaging 240 repeating units, making it highly hydrophilic and too large to penetrate skin meaningfully. It is listed in the EU cosmetics database (Cosing) with no restrictions in Annexes II or III. The Cosmetics Directive does not set specific concentration limits for this polymer, which is widely regarded as safe for cosmetic use based on its inert, large-polymer nature.
