摘要：An oil-in-water emulsion stabilized by saponified epoxidized soybean oil-grafted hydroxyethyl cellulose (H-ESO-HEC) was investigated. By using an ultrasonic method, oil-in-water emulsions were prepared by blending 50 wt % soybean oil and 50 wt % H-ESO-HEC aqueous suspensions. The influence of H-ESO-HEC concentrations on the properties of oil-in water emulsions was examined. The H-ESO-HEC concentrations in the aqueous phase varied from 0.02 to 0.40 wt %. 'When the H-ESO-HEC concentration was 0.4 wt %, the emulsion remained Stable for >80 days. The mean droplet sizes of the emulsions decreased by increasing the H ESO HEC concentration and extending the ultrasonic time. The adsorption-amounts of H-ESO-HEC at the oil water interface increased when the H-ESO-HEC concentrations in the aqueous phase increased. The Theological property revealed that the apparent viscosity of the H-ESO-HEC-stabilized oil-in-water emulsions increased when the H-ESO-HEC concentrations increased. Steady flow W170 indicated an interfacial film formation in the emulsions. The evolution of G', G", and-tan eta indicated the predominantly elastic behaviors of all the emulsions.
