A method for the encapsulation of pigment particles utilized in ink formulations by means of vinyl polymerization, within an aqueous medium, and the cosmetic products prepared with said ink formulations are disclosed. The method of encapsulation can be either that of free-radical polymerization, wherein a peroxide catalyst and a antioxidant are employed or that of a redox system wherein an ion-producing metallic pigment is utilized. The resultant cosmetic products are characterized by their overall smoothness, uniform color, and increased dispersibility of the ink formulations utilized therein, and, due to the presence of the ink formulation having the encapsulated pigment particles dispersed therein.
