ABSTRACT:
A hard film composition for capsules comprising a gelatin, from 3 to 10% by weight of an ester of a fatty acid and glycerol or polyglycerol. The capsules formed by the composition of the invention are not embrittled when the moisture in the capsule film is reduced by charging therein a hygroscopic drug, Consequently, cracking and chipping of the capsule are reduced and leakage from the capsule caused by such damage is also reduced.
