In earlier studies, it has been postulated that solutions of surfactants should be used as an original solution
for formulation of Metal Working Fluids (MWF) compositions. The negative feature of some of the fluids
was their excessive foamability whose reduction, by introducing hydrophobic foam inhibitors, was limited.
Therefore, a synthesis of new oxyalkylated derivatives of 2-ethylhexyl alcohol and sulfosuccinate obtained
from this alcohol was planned. Due to steric hindrance, these compounds exhibit low foamability. Aqueous
solutions of these surfactants were subjected to physicochemical and tribological tests.
