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 an odor-neutralizing effect. Also provided are methods of recovering water from the systems disclosed herein.
Claims19
A personal care product, comprising:
- a colloidal composition, comprising:
- a) an odor-neutralizing polymer and an aqueous solution, wherein the odor-neutralizing polymer is dispersed in the aqueous solution;
- and the odor-neutralizing polymer comprises an acrylate polymer comprising at least one acrylic acid monomer having the structure
- or salts thereof, wherein:
- R is C10-C30-alkyl, C10-C30-haloalkyl, C10-C30-alkoxy, C10-C30-haloalkoxy, C10-C30-alkenyl, or polysiloxane;
- x is an integer from 1 to about 10,000;
- and
- y is an integer from 0 to about 1,000;
- b) an odor-neutralizing agent;
- and
- c) an odor-counteracting agent;
- wherein said colloidal composition is incorporated into the personal care product selected from the group consisting of a diaper, a training pant, an absorbent underpant, an adult incontinence product, and a feminine hygiene product;
- and
- wherein the personal care product comprises a solid support and an absorbent core mixed with the colloidal composition, wherein the solid support and the absorbent core are adjacently disposed, and wherein the colloidal composition is mixed into the absorbent core during the manufacture of the absorbent core;
- and
- wherein the absorbent core has a body-facing surface adjacent to a body-side liner and a garment-facing surface adjacent an outer cover;
- and
- wherein the solid support comprises a tissue wrap made of cellulose tissue having a quantity of activated carbon therein.
