Abstract
A solid soap composition comprises a soap base and microcapsules dispersed therein, said microcapsules are prepared by using a hydrophobic liquid as a core material, forming microcapsules by covering the hydrophobic liquid with coacervate of a hydrophilic material, and then adding an electrolyte to a solution having the microcapsules dispersed therein in an amount of 8 to 100 parts by weight to 100 parts by weight of the water used in the microcapsules to dehydrate the microcapsule films. The microcapsules hardly disintegrate during the soap production process but do disintegrate during the use of the soap composition when contacted with water.
