Description

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

Hydrogen-bond-directed giant unilamellar vesicles of guanosine derivative: preparation, properties, and fusion.

Jun Sawayama et al.

Langmuir : the ACS journal of surfaces and colloids, 27(14), 8653-8658 (2011-06-09)

By mixing a small volume of THF containing guanosine derivative 1 and tetraethylenegrycol dodecyl ether (TEGDE) with water and subsequently removing TEGDE by gel permeation chromatography, micrometer-sized giant unilamellar vesicles (GUV) of 1 were successfully prepared. The vesicle membrane was

We have used a lamellar phase made of a nonionic surfactant, dodecane and water, as a model membrane to investigate its interactions with macromolecular inclusions bringing together two membranes, i.e., acting as macromolecular snaps. In systems devoid of inclusions, the

Mixed micelle formation and interfacial properties of aqueous binary surfactant combinations of dodecyltrimethylammonium bromide (C12TAB) and tetraethyleneglycol mono-n-dodecyl ether (C12E4) at 30 degrees C in absence and presence of sodium propionate (NaPr) have been investigated.
