Structural characteristics of mono-and distearin mixed monolayers spread on aqueous solutions containing sugar (glucose or sucrose) at 0.5 mol/L were studied as a function of temperature and integacial and subphase compositions. The compression isotherms were obtained using an automated Langmuir-typ
The effect of temperature on four sorbitan ester (Span 20, sorbitan monolaurate; Span 40, sorbitan monopalmitate; Span 60, sorbitan monostearate; and Span 80, sorbitan monooleate) monolayers was analyzed.

Monopalmitin films spread on aqueous solutions of sugars were studied as a function of temperature and subphase composition (sugar type and its concentration in the aqueous bulk phase). The addition of sugars expanded the structure of monopalmitin monolayers, especially if they had previously adopte
