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: ... what do you mean "cast" spiders?

gollark: Also, my parents would probably complain if I went "hmm yes I will do drugs now" one day.

gollark: Personally, such drugs seem annoying to get, and I don't really see the attraction, so meh.

gollark: I'm not sure I've actually ever heard anyone use that acronym in any case.

gollark: Nope.
