The wax or grease is emulsified by means of a water solution of the soap made from the amine and stearic acid as follows: Measure the water, amine, and stearic acid into a container or kettle and heat to 100C. When heated, the stearic acid gradually melts and can be stirred into the water to give a smooth soap solution. After the stearic acid has melted completely, allow the mixture to boil gently.
Stir carefully so that a smooth soap solution is obtained with a minimum amount of foam.
In a separate steam-heated container, melt the wax or grease and heat at 85 to 90C. Add the hot wax or grease to the boiling soap solution and stir vigorously until an even dispersion is obtained. Stir gently, but continuously, until the emulsion has cooled to room temperature in order to prevent the emulsion from becoming too viscous or the wax from graining out.
The substitution of oleic acid for stearic acid in these formulae produces less viscous emulsions. It, therefore, permits the use of a considerably h |
