Abstract
The present invention relates to a coated liquid-filled soft capsule containing a colored shell and method for making same. The shell material contains a colorant incorporated in the material in an amount sufficient to provide a visual contrast between the capsule shell and any liquid fill that escapes from the capsule shell and resides on an exterior surface of the capsule shell. This allows leaking capsules as well as other capsules that get contaminated from the leaking capsules to be identified before they are coated. This prevents coating problems in pan and/or continuous coaters associated with leaking and/or contaminated capsules. The present invention also produces pharmaceutically elegant capsules uniform in appearance without the necessity of coloring the coating.
