Abstract

Monolayers of two glycerol esters, 1-monooleoylglycerol and 1-monostearoylglycerol, were studied at the air-water interface in the 15–30‡C temperature range.

From the experimental isotherms (surface pressure vs area and surface potential vs area) the surface phases of the esters were inferred.

The miscibility between the two esters was discussed in relationship to the interfacial orientations and distributions and to the surface phases of the esters.

The results obtained supported and strengthened the empirical rule on miscibility previously found [1–7], i.e., for non-ionic compounds the same interfacial orientation of the hydrophobic chains is required in order to have bidimensional miscibility between the components.
