Abstract
A method of producing oil-containing microcapsules in which complex coacervation is carried out using a gellable hydrophilic colloidal material and carboxymethyl cellulose together with the oil in an emulsion, which is subsequently subjected to preservation characterized by the subsequent steps of: (a) emulsifying an oil in a solution consisting essentially of the gellable hydrophilic colloidal material to form a colloidal material/oil emulsion. (b) adding a carboxymethyl cellulose solution to the colloidal material/oil emulsion in a dry weight ratio of colloidal material to active carboxymethyl cellulose content used between 1: 0.35 and 1: 1.2; (c) effecting complex coacervation to form mononuclear microcapsules each comprising an oil droplet as the core with a wall consisting of the colloidal material and carboxymethyl cellulose around the core and, (d) gel the walls of the microcapsule.
