| Abstract/Summary |
Foaming properties of aqueous solutions of the nonionic surfactant polyoxyethylene dodecyl ether (C12EO n ) were studied at 298 K. Four different EO chain lengths, namely C12EO3, C12EO5, C12EO7, and C12EO9, were considered. The foams obtained from C12EO3 or C12EO5 were extraordinary stable retaining a constant volume for more than 20 h. The presence of lamellar liquid crystalline phases was mainly responsible for the super-stable aqueous foams.
