Abstract

PURPOSE:To obtain micro-capsules releasing immediately a core substance in a digestive organ, by adding a carbonate to the core substance in ethyle cellulose micro-capsules containing the core substance such as a drug, etc. and/or to the wall film of ethyl cellulose. CONSTITUTION:A core substance such as a drug, food, etc. is dispersed into a solution containing ethyl cellulose as a agent for forming a wall film ethyl cellulose is subjected to phase separation in the presence of a carbonate to form an ethyl cellulose wall film on the core substance, or the core substance is blended with the carbonate or tge carbonate and an organic acid, and the ethyl cellulose wall film is formed in the presence or absence of the carbonate on the core surface like the above-mentioned process, to give the titled immediately releasing micro-capsules containing the carbonate in the core substance of the ethyle cellulose micro-capsules containing the core substance and/or in the ethyl cellulose wall film of microcapsules.
