  • Patent number: 5801220
    Abstract: A rapid disintegrating and dispersing composition for thickening liquid waste into a thixotropic gel comprises a polymeric acrylic resin and a colloid-forming mixture of microcrystalline cellulose and sodium carboxymethylcellulose. Additional ingredients preferably used in making a tableted form of the composition include microcrystalline cellulose per se, polyvinylpolypyrrolidone, magnesium stearate and amorphous silica. The tablet is placed in suitable containment means such as a containment bag. The thixotropic properties of the composition enable the gelled waste to be restored to a liquid when small amounts of hand pressure are applied to the waste containment bag, thereby providing a convenient and simple means for disposal.

  • Patent number: 4738850
    Abstract: In accordance with the present invention, a controlled release formulation is provided from which a drug, selected from the group consisting of angiotensin converting enzyme inhibitors and ascorbic acid, is released at a substantially controlled rate. The controlled release formulation of the invention is comprised of a reactive matrix of from about 5 to about 80 percent by weight of the drug in combination with from about 5 to about 70 percent by weight of poly[(1.fwdarw.4)-2-amino-2-deoxy-.beta.-D-glucose] (also referred to as chitosan herein). Further in accordance with the present invention there is provided a gel-like complex formed of the drug and the chitosan in environments ranging from neutral to acidic.
