Pentaethylene glycol monododecyl ether (C12E5) is a nonionic surfactant formed by the ethoxylation of dodecanol (lauryl alcohol) to give a material with 5 repeat units of ethylene glycol.
Multilamellar vesicle formation[]
The lamellar phase at 40wt% of C12E5 dissolved in D2O form multilamellar vesicles under shear rate.[needs context][3]
