Beschreibung

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
