Procedure

One hundred grams of sericite was added to 450 ml of water and mixed using a home type mixer until well dispersed. Four grams of sodium N-myristoyl-L-glutamate having an HLB value of 4, was dissolved in 50 ml of water heated at 60° C. then added to the above mixture and mixed for 10 minutes. While this was being stirred, 2 chemical equivalents of aluminum chloride aqueous solution, based on the sodium N-myristoyl-L-glutamate, was added dropwise. Four grams of glycerin having an HLB value of 20 was dissolved in 50 ml of water heated at 50° C. then added to the above mixture and mixed for 10 minutes. The product was filtered with suction using a Buchner funnel, followed by rinsing with purified water. The filter cake was then baked in an over for two hours after the filter cake reached a temperature of 100° C. to further dehydrate the filter cake. The cake was crushed and pulverized to a powder after cooling. This resulted in sericite pigment chemically immobilized with aluminum N-myristoyl-L-glutamate; the glycerin did not chemically immobilize itself to the pigment, but instead was washed away.
