PURPOSE:To obtain a polysaccharide spherical substance prevented from a phase reversion, by bringing polyscaccharide containing kappa-carrageenan gelled by a potassium-containing anionic surfactant to an outer layer and using a water imcompatible liquid as an inner layer. CONSTITUTION:Polysaccharide containing 30% or more, pref., 50% or more of kappa-carrageenan gelled by a potassium-containing anionic surfactant (stearic acid, palmitic acid or oleic acid) is brought to an outer layer and a water imcompatible liquid (chloroform or dichloromethane) is used as an inner layer to form a polysaccharide spherical substance. By this method, the diffusion of the org. liquid of the inner layer to the outer layer is exdtremely reduced and a phase reversion can be prevented. |
