General description

Tetraethylene glycol monododecyl ether (C12E4) is a nonionic surfactant. It is used as a stabilizer in several phase behavior and evaporation studies. This polyoxyethylated lauryl ether surfactant is a water-soluble surfactant.

Application

Tetraethylene glycol monododecyl ether (C12E4) has been used:


  • as a water-soluble surfactant in computational and physical experiments to report the post-deposition motion of the surfactant front and the deformation of the subphase surface using Marangoni flow and capillary waves
  • to study its mixed micellization and interfacial properties in the absence and presence of sodium propionate
  • to investigate the phase transformation of C12E4 aqueous solutions by Rayleigh light scattering (RLS) when adopting different heating ways
