Gelatin capsules are capsules made of gelatin as the main material, and those that do not contain drugs are called hollow capsules for filling drugs. The medicine is directly wrapped by the dropping method, the steel moulding method or the rotating moulding method to form a soft capsule. In order to improve the properties of capsules and give special functions, various additives can be added, such as plasticizers (glycerol, sorbitol, etc.), sunscreens (qin dioxide, barium sulfate, etc.), slow-release and enteric excipients (phthalates, etc.) Cellulose acetate formate, shellac, propyl methylcellulose phthalate, methyl methacrylate copolymer, etc.), surface active agents (Tween, dodecyl sulfate Sodium, etc.), as well as bactericides, flavors and colors, etc.
