Within chemical compound surfactants, pentaethylene glycol monododecyl ether (C12E5) is a nonionic surfactant. It is formed by the ethoxylation chemical reaction of dodecanol (lauryl alcohol) to give a material with 5 repeat units of ethylene glycol.
Multilamellar vesicle formation
Within the study of biological membranes and cell biology, for vesicle formation, the lamellar phase at 40wt% solution of C12E5 dissolved in D2O form multilamellar vesicles under shear rate.{{cite journal | doi = 10.1021/la1046047 | pmid = 21261313 | title = Effect of Shear Rates on the MLV Formation and MLV Stability Region in the C12E5/D2O System: Rheology and Rheo-NMR and Rheo-SANS Experiments | year = 2011 | last1 = Gentile | first1 = Luigi | last2 = Rossi | first2 = Cesare Oliviero | last3 = Olsson | first3 = Ulf | last4 = Ranieri | first4 = Giuseppe Antonio | journal = Langmuir | volume = 27 | issue = 6 | pages = 2088}}
