Abstract: Nonionic alcohol ethoxylate surfactants are well known to form gel phases in water typically between 30-70%. However, a noteworthy, gel phase was identified when using a long chain fatty alcohol ethoxylate with a specific catalyst that creates a viscoelastic gel at relatively low concentrations. Surfactants are surface active molecules that have a unique ability to form self-aggregates called micelles. These micelles have various orientations from spheres, rods, and bilayers that can alter viscosities based on its hydrophobic and hydrophilic portions. This paper will focus on fatty alcohol ethoxylates above octadecanol and investigate rheological, surface chemistries and potential applications areas.
