Procedure

To 100 parts of water, 60 parts of stearic acid was added, and the stearic acid was completely melted by heating to 72° C. i.e. the melting point of the stearic acid, with stirring. In this state, stearic acid is present as oil droplets in water. Then, a mixture comprising 73.9 parts of 10% aqueous ammonia and 100 parts of water, was dropwise added to the above-mentioned molten stearic acid/water mixture, with stirring, to obtain an aqueous dispersion of ammonium stearate having a solid content of 20%.
