ABSTRACT:
A safe and non-toxic process is provided for treating hot, newly formed soft elastic gelatin capsules to avoid their sticking to one another and to remove matter in the form of oils, pastes, and solid particles from exterior surfaces of the capsules, comprising the steps of: 1) cooling the capsules to aid in preventing capsule deformation and to aid in removing aqueous moisture from exterior surfaces of the capsules, and 2) contacting the capsules with an absorbent material to remove the matter from the exterior surfaces of the capsules. Alternatively, for certain type capsules, the process of the present invention may comprise the single step of absorption of matter from the exterior surfaces of the capsules.
