PEG 400 is strongly hydrophilic.The partition coefficient of PEG 400 between hexane and water is 0.000015 (log =), indicating that when PEG 400 is mixed with water and hexane, there are only 15 parts of PEG400 in the hexane layer per 1 million parts of PEG 400 in the water layer.
PEG has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes. [18] PEG is a component of the propellent used in UGM-133M Trident II Missiles, in service with the United States Navy. [19] PEG has been used as a solvent for aryl thioether synthesis. [20]
Poloxamer 407 is a hydrophilic non-ionic surfactant of the more general class of copolymers known as poloxamers.Poloxamer 407 is a triblock copolymer consisting of a central hydrophobic block of polypropylene glycol flanked by two hydrophilic blocks of polyethylene glycol (PEG).
The U.S. Code of Federal Regulations allows no more than 0.2% of diethylene glycol in polyethylene glycol when the latter is used as a food additive. [11] In Australia , it is only allowed at less than 0.25% w/w of DEG as an impurity in polyethylene glycol (PEG), [ 12 ] even in toothpaste.
