General description

Tetraethylene glycol monooctyl ether is a surfactant.

Application

Reported to be useful in solubilizing membrane proteins.
Tetraethylene glycol monooctyl ether has been used in a study to assess thermal diffusion behavior of nonionic surfactants in water. It has also been used in a study to investigate unusual micelle and surface adsorption behavior in mixtures of surfactants.
