  • Fast dissolving orally consumable films containing a taste masking agent
    Patent number: 7648712
    Abstract: Physiologically acceptable films, including edible films, are disclosed. The films include a water soluble film-forming polymer, such as pullulan, and a taste masked pharmaceutically active agent, such as dextromethorphan. The taste masking agent is preferably a sulfonated polymer ion exchange resin comprising polystyrene cross-linked with divinylbenzene, such as AMBERLITE. Methods for producing the films are also disclosed.
    Type: Grant
    Filed: May 5, 2006
    Date of Patent: January 19, 2010

  • Aluminum hydroxycarbonate gel
    Patent number: 4937061
    Abstract: Continuous production of aluminum hydroxycarbonate gel by continuous reaction of aluminum salt solution with mixed alkaline carbonate and bicarbonate solution under homogeneous conditions in a relatively small reaction vessel, and continuing the reaction in a subsequent reaction vessel under controlled pH. The product gel is separated from the non-aluminum cation containing reaction mixture within less than about 6 hours, whereby formation of poorly soluble addition reaction products such as dihydroxy aluminium sodium carbonate, which contribute undesired non-aluminum cations to the gel product, is reduced. The aluminum salt solution is adjusted in pH by adding to it a portion of the mixed carbonate and bicarbonate solution to obtain a clear solution of pH 3.5 to 4.0. This results in a smooth, creamy gel with less objectionable chalky mouth feel.
