Abstract

Hypothesis Due to its huge polar headgroup, octaoxyethylene octyl ether carboxylic acid (C8E8CH2COOH = Akypo LF2™) is supposed not to be able to change its curvature sufficiently to form bicontinuous microemulsions. Instead, upon adding an oil to the binary water – surfactant system, excess oil could be squeezed out or a biliquid foam could form. Experiments An auto-dilution setup was used to ...
