Abstract
Seven samples of surfactants were prepared from soapstock (waste from sunflower-seed oil production) under different conditions of base hydrolysis. The surfactant properties of the products at the solution-air boundary (surface activity, adsorption layer thickness, molecular area, work of adsorption, limiting adsorption) were studied.
