Abstract

PURPOSE:To prepare capsules of high tunic density, excellent stability and solubility by dissolving a fatty oil which is solid at ordinary temperature and a polymer into an organic solvent, to which core material is hardly soluble or insoluble and which dissolves fatty oil in heated state and sepates it into phases in cold state, and by dispersing the core material into the solution, followed by cooling.
