To prepare the anionic emulsion, the ammonium hydroxide is added to the water and the oleic acid is added to the plasticizer. The oleic acid-plasticizer mixture is then added slowly to the water and ammonium hydroxide solution with vigorous, high-shear agitation such as that obtained with an Eppenbach Homo-mixer. To prepare the nonionic emulsion, the "Triton" X100 is added to the water and the "Triton" X45 is added to the plasticizer. The "Triton" X45-plasticizer mixture is then added slowly to the "Triton" X100 and water again with vigorous, high-shear agitation.
