AQUEOUS COMPOSITION FOR ENTERIC HARD CAPSULES, PRODUCTION METHOD FOR ENTERIC HARD CAPSULES AND ENTERIC HARD CAPSULES |
摘要 |
An aqueous composition for an enteric hard capsule, a method of preparing an enteric hard capsule, and an enteric hard capsule prepared using the method. The aqueous composition for an enteric hard capsule includes an enteric base material, a capsule forming aid, and a neutralizing agent. The method of preparing an enteric hard capsule includes: preparing an aqueous composition by dissolving an enteric base material, a capsule forming aid, and a neutralizing agent in water; preheating the aqueous composition to a temperature that is less than the gelation temperature for the aqueous composition; immersing a mold pin heated to a temperature that is greater than the gelation temperature for the aqueous composition into the aqueous composition; taking the mold pin out of the aqueous composition to obtain a film formed on the mold pin; and maintaining the film at a temperature that is equal to or greater than the gelation temperature for the aqueous composition for a predetermined period of time to fix the film on the mold pin and drying the film. |
