The focus of this study was the preparation of novel bio based polyglycerol emulsifiers characterized by a one pot synthesis, thus by modified properties with respect to interfacial activity and effectiveness as emulsion stabilizers. The final products of the esterification process, carried out in the presence of carboxylates were used directly as emulsifiers (without purification or fractionation). Polyglycerol emulsifiers obtained in proposed conditions can be tailored to stabilize the defined emulsion system. The modification of the surface activity of emulsifiers may be obtained by programming the fatty acid acyl group in the polyglycerol ester as well as the hydrocarbon chain length in sodium soap and concentration of this compound in the reaction mixture.
