Description
Various polyoxyethylene (POE) sorbitan fatty acid esters were synthesized, and some properties of these reaction products were studied. Solubilizing powers of azobenzene and clouding points of aq. solutions of POE sorbitan monolaurates were greatly affected by not only the amounts of added ethyleneoxide (EO), but also the constituents of used sorbitan monolaurates as raw materials and reaction conditions of additional polymerization of EO.<BR>O/W emulsions of liquid paraffin were prepared by various POE sorbitan fatty acid esters combined with Arlacel 60 (sorbitan monostearate) in various ratio, and were studied about viscosities of emulsions, HLB values and inversion temperatures. Viscosities of emulsions were measured by MacMichael's rotating cup viscometer and were compared by the torsional angles of viscometer at 50 r.p.m. with each sample. From the diagrams of viscosities of O/W emulsions vs. combination ratio of two emulsifiers, there were two maximum values, except POE sorbitan trioleate.<BR>Deviations between experimental values of HLB and calculated values by Griffin's equation were not so great as that of sorbitan fatty acid esters.<BR>Inversion temperatures became higher when ratio of POE sorbitan fatty acid esters increased. When ratio of emulsifiers to oil phase or ratio of oil phase to water phase were increased, inversion temperatures became lower and their ranges became wider.
