Langmuir adsorption isotherms for different organic solutions of cholesterol. Medina-Meza 3 and J. Tejero-Andrade 1. E-mail: carlo. Recibido 7 de Noviembre de Aceptado 22 de Marzo de In this work, the surfactant properties of cholesterol in organic solvents are studied.

Hexane, iso -octane, iso -dodecane and toluene were used as the hydrophobic phase, and bidistilled water was used as the water phase. The appearance of turbidity associated with cholesterol crystallization is observed to be below concentration limits in all samples, because the liquid-liquid interface reduces the energy barrier required for nucleation.

Finally, Szyszkowski-Langmuir constant K L and Gibbs energy of absorption were calculated for the binary systems. Adamson, A. Physical Chemistry of Surface, 6th Ed. Chen, P.
