Abstract

생물학적으로 분해 가능한 중합체를 바탕으로 생물학적 분해 가능한 용매를 사용해서 그 이외의 독성 용매 없이도 마이크로캡슐을 생산하는 마이크로캡슘의 제조 과정에 관해 설명하였다. 사용된 용매는 일차 에스테르이고 이 에스테르는 C1-C3-알콜과 C2-C3-모노카르본산과 에스테르의 혼합물로 이루어져 있다. 이러한 용매는 첨가물 C2-C3-알콜을 가지고 있을수 없다. 작용 물질로써 물에 녹거나 녹지 않는 물질이 사용된다. 약제, 펩타이드, 단백질, 효소, 왁찐과 같이 물에 용해되는 작용 물질은 중합체 용액에서 물로된 용액으로써 미세분된다. 마이크로캡슐은 용액의 분무, 현탁액, 작용 물질과 생물학적 분리 가능한 중합체로부터의 W/O-미세분을 통해 얻어진다. 이과정은 약제, 왁찐, 효소 제조에 사용된다.
