Procedure

A solution containing 67.8% water, 1.2% of potassium carbonate, 25% paraffin, 5% stearic acid and 1% oleic acid is formed by melting the stearic acid, oleic acid and paraffin at about 90° to 100° C. and adding an aqueous solution of the potassium carbonate at 90° to 100° C. The resultant solution is stirred for more than 10 minutes at the temperature of 90° to 100° C. in a mixer at 1500 to 3600 r.p.m. until the apparent volume swells to about twice the original volume. This well stirred solution is cooled to 25° C. under stirring.
