POLYOXYALKYLENE GLYCOL GELATIN CAPSULE FILL FORMULATIONS COMPRISING CROSSLINKED CARBOXYLIC COPOLYMERS

摘要

Disclosed are fill compositions suitable for carrying pigment and encapsulation within gelatin capsules comprising: (a) a polyoxyalkylene glycol having a mean molecular weight of from about 200-500; (b) glycerol; (c) water; (d) an oleaginous material; (e) a carboxylic copolymer; and (f) a neutralizing agent for the carboxylic polymer in an amount effective to neutralize at least about 75 % of the carboxylic acid groups on the polymer. Also disclosed are gelatin capsules containing such compositions and methods for preparing the fill compositions.
