Pentaethylene glycol monododecyl ether
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.[3]
gollark: *Ah*, right.
gollark: What?
gollark: ```lua local autorun = potatOS.registry.get "potatOS.autorun" if type(autorun) == "string" then autorun = load(autorun) end if type(autorun) == "function" then process.spawn(autorun, "autorun") end```
gollark: Okay, done, that is now easy.
gollark: Hold on a few minutes.
