The surface activity and dynamics of adsorption surface layer formation of individual solutions of 5-methylresorcinol (MR) and its mixed solutions with lysozyme on air/solution (0.05 M phosphate buffer, pH 6.0) interface under conditions of MR maximally exceeding hydrolytic activity of lysozyme are studied using method of dynamic drop tensiometry. The thermodynamic parameters of adsorption are determined based on the isotherms. It is established that MR possesses lower surface activity in comparison to traditional surfactants. Methylresorcinol increases the surface activity and lysozyme adsorption rate at the air/solution interface in the entire concentration range covered.
