実験手順

One hundred grams of mica pigment was added to 450 ml of water and mixed using a home type mixer until well dispersed. Three grams of hydrogenated egg yolk lecithin (phospholipids 30%, neutral fat 70%) having an HLB value of 2 was dissolved in 100 ml of water heated at 95° C. then added to the above mixture and mixed for 10 minutes. While this was being stirred, 2 chemical equivalents of aluminum sulfate aqueous solution, based on the phospholipids, was added dropwise. Four grams of potassium gluconate having an HLB value of 20 was dissolved in 50 ml of water heated to 50° C. then added to the above mixture and mixed for 10 minutes. While this was being stirred, 2 chemical equivalents of zinc sulfate aqueous solution, based on the potassium gluconate, was added dropwise. The product was filtered with suction using a Buchner funnel, followed by rinsing with purified water. The filter cake was then baked in an oven for 3 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 a mica pigment chemically immobilized with lecithin and zinc gluconate.
