PEG-6

PEG-6 is a synthetic polymer of ethylene glycol, commonly used as a solvent, humectant, and emulsifier in cosmetic and personal care products. Its primary role is to dissolve other ingredients, help retain moisture, and improve the texture and spreadability of formulations. It is generally considered safe for topical application.
