Abstract

A pseudo-plastic or thixotropic carrier having anti-malodorous components dissolved or suspended therein is sprayed on the internal surfaces of an ostomy bag or pouch. The viscoelastic properties of the carrier allow the composition to be conveniently dispensed from a spray bottle into the ostomy bag and retained on the inner walls thereof without being displaced therefrom by incoming waste during use of the ostomy bag. This allows the composition to continue to deodorize the ostomy bag headspace even after waste material begins to fill the bag.

Claims (9)

1. A method of reducing malodors associated with use of an ostomy bag comprising applying to inner walls of an ostomy bag a composition comprising a pseudo-plastic or thixotropic liquid and at least one ostomy deodorizing compound dissolved or dispersed therein, wherein said pseudo-plastic or thixotropic liquid has a kinetic viscosity of not more than about 2,000 cps and a stationary viscosity of not less than 10,000 cps.

2. The method of claim 1 wherein said deodorizing compound comprises a chlorinating agent.

3. The method of claim 2 wherein said deodorizing compound is Chiloranime-T.

4. The method of claim 1 wherein said pseudo-plastic or thixotropic liquid comprises water and a carrier solid selected from the group consisting of inorganic thickeners, organic polymers, and mixtures thereof.

5. The method of claim 4 wherein said carrier solid comprises an inorganic thickener, said inorganic thickener is selected from the group consisting of sodium magnesium silicate, sodium lithium magnesium silicate, and mixtures thereof.

6. The method of claim 4 wherein said carrier solid comprises an organic polymer, said organic polymer is selected from the group consisting of xanthan gum, carboxymethylcellulose and its alkali metal salts, polyacrylates, guar gum, sodium alginate, Iota Carrageenan, Gellan gum and mixtures thereof.

7. The method of claim 4 wherein said inorganic thickener has a particle size of not greater than about 200 nanometers.

8. The method of claim 4 wherein said inorganic thickener is present in an amount of about 2% to about 10% of said composition.

9. The method of claim 4 wherein said organic polymer is present in an amount of about 0.01% to about 2% of said composition.
