Abstract
Abstract Urinary and intestinal tract excrement, such as from a stoma patient, is thickened by admixture with a cross-linked water-swellable polymer, preferably including (meth)acrylic acid, nitrile and/or amide units. A hydrophilic adsorption agent such as silicic acid may also be included along with perfume materials, binders and/or enzyme inhibitors. By thickening, it prevents sloshing of the contents, reduces odors and facilitates ultimate disposal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
45 words
A method of thickening urinary tract and intestinal excrement comprising mixing said excrement with about 1 to 5 grams of a cross-linked water-swelling polymer per 100 ml of excrement and with about 0.1-0.5 parts of a hydrophilic adsorption agent per part by weight of polymer.
Claim 2
Independent Claim
45 words
A method of thickening urinary tract and intestinal excrement comprising mixing said excrement with about 1 to 5 grams of a cross-linked water-swelling polymer per 100 ml of excrement and with about 0.1-0.5 parts of a hydrophilic adsorption agent per part by weight of polymer.
Claim 3
Dependent Claim
25 words
A method according to claim 1, wherein the polymer comprises units of at least one of acrylic acid, methacrylic acid, acrylamide, methacrylamide, acrylonitrile and methacrylonitrile.
Claim 4
Dependent Claim
25 words
A method according to claim 2, wherein the polymer comprises units of at least one acrylic acid and methacrylic acid in acid or salt form.
Claim 5
Dependent Claim
29 words
A method according to claim 2, wherein the polymer comprises units of one of the recited monomers plus units of vinyl pyrrolidone or a second of the recited monomers.
Claim 6
Dependent Claim
32 words
A method according to claim 2, wherein the polymer comprises units of at least one of acrylic acid and methacrylic acid plus units of at least one of acrylamide, methacrylamide and acrylonitrile.
