Effects of diethylenetriamine and Aerosol OT on the stability of oil-in-water emulsion stabilized by interfacial polyurea film.
The stability of oil-in-water emulsions containing a triisocyanate soluble in the oil phase and an amine in the water phase was investigated. The oil component was di-n-butyl phthalate (DBP) containing Aerosol OT as an emulsifier. The time required for the average size parameter to reach a constant value was studied. It was found that the polyurea film produced by an interfacial polymerization reaction between the amine and the triisocyanate contributed to forming a stable emulsion at a lower Aerosol OT concentration, but at a higher Aerosol OT concentration the amine did not show any effect on the emulsion stability.
