Potassium oleate and water

The change of solubility areas with electrolyte content is shown in Figure 2. The solubility area for the pentanol solution of potassium oleate and water (—. —. —, Figure 2) shows a minimum water amount for solubilization. The minimum amount of water is proportional to the amount of soap present the solubility limit to the right gives a molecular water potassium oleate ratio of three, the minimum number of water molecules to bring the soap into solution. The solubility area is approximately triangular with maximum water solubilization at 12% (w/w) potassium oleate, 33% pentanol, and 55% water. The potassium oleate pentanol ratio is. 36 at that point. 

Figure 3. At low H20 content ( 25% ) no association structures are present in the pentanol solution of potassium oleate and water. Pentanohpotassium...
