PEG-150
What PEG-150 is & what it does
PEG-150 is a high molecular weight polyethylene glycol, a water-soluble polymer made by reacting ethylene oxide repeatedly. In cosmetic and sunscreen formulas it works mainly as a thickener and viscosity builder, giving lotions and gels more body and a smoother flow. It is also mildly humectant and helps stabilize the overall texture. PEG-150 is widely used at low levels and is generally considered a well-tolerated formulation aid.
