Abstract:
1. A method for controlling the odor that emanates from animal waste comprising: providing an animal litter comprising (1) an absorbent material suitable for use as an animal litter, (2) a hydrophilic modified starch, (3) a water soluble acidic solid material, and (4) a carbonate-containing or percarbonate-containing solid material wherein said animal litter enables encapsulation of solid animal waste and/or urine clumps; contacting the animal litter with a moisture containing solid animal waste and/or urine clump; dissolving the acidic solid material with moisture contained in the solid animal waste and/or urine clump to initiate a gas-generating reaction; creating a foam from the gas-generating reaction between the acidic solid material and the carbonate-containing or percarbonate-containing solid; perpetuating the gas-generating reaction by creating water from the reaction between the solid acid and the carbonate-containing or percarbonate-containing solid material; covering said solid animal waste; substantially encapsulating the solid animal waste and/or urine clump with the foam produced by the gas-generating reaction; using the hydrophilic modified starch to create a structural network within the foam to give the foam longevity and shape to provide structural integrity to the foam shape as the foam dries; allowing the foam to dry; and creating a dry foam that substantially encapsulates the solid animal waste and/or urine clump with a shell of animal litter to physically block the emanation of odor from the solid animal waste and/or urine clump.
