It is well-known that certain mixtures of surfactants can provide better performance than pure surfactants for a wide variety of applications. A stable water-in-oil(W/O) nano-emulsions was reported to be prepared using sorbitan monooleate (Span80), polyoxyethylene 20 sorbitan monooleate (Tween80), decane oil and water1). The w/o emulsion was prepared by spontaneous emulsification2). The organic phase was used to mix the n-decane and varying ratio (v/v) between Span80 and Tween80 surfactants. In this work, we investigated that a partial physical property of the emulsion such as partial molar volume of water, emulsion stability by size distribution along with time. Solubilization of fibroin and its hydrolysate was performed by using the emulsions of varying water fraction. Excess peptide precipitates were removed by filtration. The level of solubilization of peptide was between 0.1 - 1.1 mg/ml of transparent emulsion. Fibroin was solubilized upto 16 mg/L of transparent emulsion.
