Materials and methods for deoderization of mammalian urine

Abstract

Disclosed are compositions, materials, garments, devices, and methods for controlling or neutralizing offensive odors associated with mammalian urine. For example, disclosed are personal care products (e.g., diapers), deodorizing colloidal compositions, urine-based fertilizers, portable urination systems, and methods of their use. Such deodorizing colloidal compositions, urine-based fertilizers, portable urination systems are characterized in that they contain an acrylate polymer comprising at least one acrylic acid monomer or salt thereof, which imparts a odor-neutralizing effect. Also provided are methods of recovering water from the systems disclosed herein.
