Do humidity conditions need to be considered when storing pharmaceutical hard gelatin empty capsules?

When storing pharmaceutical hard gelatin empty capsules, it is indeed necessary to consider humidity conditions. This is because hollow capsules have the characteristics of being prone to breakage due to low water content and softening and deformation due to excessive water content. Therefore, during the storage process, it is necessary to strictly control the humidity conditions to ensure the quality and stability of the capsules.
Specifically, the humidity of the storage environment for hollow capsules should be maintained between 35% and 65% to avoid excessively dry or humid air. If the humidity is too high, it may make the capsule shell softer, affecting the sealing and stability of the capsule; If the humidity is too low, it may make the capsule brittle or deformed, which also affects the sealing and stability of the capsule.
In addition, in practical operation, it is also necessary to avoid exposing the hollow capsules to high temperature, high humidity or excessively dry environments, in order to avoid affecting the quality and stability of the capsules. Therefore, when storing pharmaceutical hard gelatin empty capsules, they should be placed in a cool, dry, and well ventilated place, and ensure that the humidity of the storage environment is within an appropriate range.
