Separately, 60 grams of oleic acid were mixed with 30 grams of calcium stearate and melted at about 230° F. until a clear liquid was obtained (the oleate lowers the effective melting point). After melting, an additional 240 ml of the 5% KOH solution were added slowly so that the temperature of the mixture was about 200° F. The KOH reacted with the oleic acid to form the acid salt, potassium oleate (KOl). The amount of KOH added at this stage was not sufficient to achieve full neutralization of the acid, which would have made too stiff a soap.
