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.
