Capsule shell |
摘要 |
Capsule shells for pharmaceutical use are presently made from gelatin. Use of water-soluble starch ethers instead of gelatin facilitates the production of the shells and produces improved shells. Preferred material is 2-hydroxypropyl starch made from high-amylose starch and having about 0.3 to 2.5 hydroxypropyl groups per glucose unit of the starch.
