| '''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 cigarette]]s (personal vaporizers).

| ==Chemical properties==
| |
| PEG 400 is strongly [[hydrophilic]]. The [[partition coefficient]] of PEG 400 between hexane and water is 0.000015 (log<math>P = -4.8</math>), indicating that when PEG 400 is mixed with water and hexane, there are only 15 parts of PEG 400 in the hexane layer per 1 million parts of PEG 400 in the water layer.<ref>{{cite journal

| PEG 400 is soluble in water, acetone, alcohols, benzene, glycerin, glycols, and aromatic hydrocarbons, and is slightly soluble in aliphatic hydrocarbons.

Hi there, I am Alyson Pomerleau and I think it sounds quite great when you say it. Her family life in Ohio but her spouse wants them to transfer. He is an information officer. To climb is something I truly enjoy doing.
