Amphiphilic cellulose as stabilizer for oil/water emulsion

Abstract

IN THIS work, amphiphilic ethyl amino-cellulose as oil/water emulsion stabilizer was prepared from cellulose extracted from bleached bagasse pulp. By periodate oxidation of cellulose the corresponding C-2/C-3 dialdehyde cellulose produced, which reacted with ethyl amine to obtain ethyl amino-cellulose (amphiphilic cellulose) through Schiff's base reaction (reductive amination). The produced ethyl-amino cellulose has a great attention in soybean oil/water stabilization. The amphiphilic cellulose was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, Transmission electron microscopy (TEM), Thermal gravimetric analysis (TGA), and Differential scanning calorimetry (DSC). Fourier transform infrared spectroscopy has been proved the incorporation of soybean oil in ethyl amino-cellulose as there is new groups appeared in the Fourier transform infrared spectra of the prepared emulsion. TEM was used to prove the nano-size of the prepared samples. TGA and DSC proved the thermal stability and melting temperature. The prepared sample was successfully applied as a stabilizer for soybean oil in water emulsion.
