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
PEG 400 is strongly hydrophilic. The partition coefficient of PEG 400 between hexane and water is 0.000015 (log P = − 4.8 {displaystyle P=-4.8} ), 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.[1]
PEG 400 is soluble in water, acetone, alcohols, benzene, glycerin, glycols, and aromatic hydrocarbons, and is slightly soluble in aliphatic hydrocarbons
