Abstract
Using the methods of surface balance we compared the effects of different phosphatidylcholines and synthetic surfactant Exosurf on the equilibrium surface tension at the air-water interface. It was found that dipalmitoyl-lecithin, the principal component of natural surfactant, and its synthetic substitutes can be replaced by other phosphatidylcholines, in particular, by modified soybean phosphatidylcholine phospholipon. It was demonstrated that equilibrium surface tension is an informative characteristic in the assessment of potential components for synthetic surfactants.
