This note, modifies the analytic interface profile, proposed by LFT to account for the adsorption of the third minority component along the interfaces. It is shown that the modified analytic interface profile using hyperbolic tangent variational approximation properly describes the interfaces, profile for low degrees of adsorption of C. A low degree of adsorption is seen in ternary polymer blends. In ternary small-molecule mixtures and/or alloys, however, since large adsorptions are found along the interfaces, the MHTVA cannot describe such interfaces.
