PEG 400 (polyethylene glycol 400) is a low-molecular-weight grade of polyethylene glycol. It is a clear colorless viscous liquid. Due in part to its low toxicity PEG 400 is widely used in a variety of pharmaceutical formulations. More recently it has been used to make E-Liquid for electronic cigarettes (personal vaporizers).
