Abstract

A composition for odor reduction and bacterial control on a textile material is provided. The composition has a GRAS antimicrobial/preservative additive. The composition may contain an essential oil. The GRAS antimicrobial/preservative additive can be a minimum risk pesticide. The composition may have a carrier. A method of using the composition and an article treated with the composition are also provided.

First claim

What is claimed is:

3 . The composition according to claim 1 , wherein the GRAS additive is a minimum risk pesticide.

4 . The composition according to claim 1 , wherein the GRAS additive is selected from the group consisting of sodium benzoate, potassium sorbate, and a combination thereof.

5 . The composition according to claim 1 , wherein the GRAS additive is a food preservative.

6 . The composition according to claim 1 , wherein the GRAS additive is an organic acid.

7 . The composition according to claim 6 , wherein the organic acid is selected from the group consisting of benzoic acid, propionic acid, sorbic acid, citric acid, lactic acid, ascorbic acid, acetic acid, erythorbic acid, fumaric acid, malic acid, glycolic acid, a derivative thereof, and a combination thereof.

8 . The composition according to claim 7 , wherein the organic acid is selected from the group consisting of benzoic acid, sorbic acid, citric acid, and a combination thereof.

9 . The composition according to claim 1 , wherein the essential oil is selected from the group consisting of cedarwood oil, tea tree oil ( Melaleuca alternifolia ), eucalyptus oil ( Eucalyptus globulus or E. radiata ), clove oil ( Eugenia caryophyllata ), oregano oil ( Origanum vulgare ), thyme oil ( Thymus vulgaris ), geranium oil ( Pelargonium graveolens ), cinnamon bark oil ( Cinnamomum zeylanicum ), peppermint oil ( Mentha piperita ), lemongrass oil ( Cymbopogon flexuosus ), basil oil ( Ocimum basilicum ), lavender oil ( Lavandula angustifolia ), lemon oil ( Citrus limon ), rosemary oil ( Salvia rosmarinus ), bergamot oil ( Citrus bergamia ), perilla oil ( Perilla frutescens ), coriander oil ( Coriandrum sativum ), citron oil ( Citrus medica ), and a combination thereof.

10 . The composition according to claim 1 , further comprising an odor mitigation compound.

11 . The composition according to claim 10 , wherein the odor mitigation compound is selected from the group consisting of a metal oxide, activated carbon, sodium carbonate, calcium carbonate, zinc rincoleate, and a combination thereof.

12 . The composition according to claim 1 , wherein the GRAS additive or component has a total concentration of 5% to 60% active by weight of the composition.

13 . The composition according to claim 1 , wherein the GRAS additive or component has a total concentration of 10% to 50% active by weight of the composition.

14 . The composition according to claim 6 , wherein the organic acid is present at a total concentration of 5% to 60% active by weight of the composition.

15 . The composition according to claim 6 , wherein the organic acid is present at a total concentration of 10% to 50% active by weight of the composition.

16 . The composition according to claim 2 , wherein the essential oil is present at a total concentration of 1% to 20% by weight of the composition.

17 . The composition according to claim 10 , wherein the odor mitigation compound is present at a total concentration of 1% to 20% by weight of the composition.

18 . The composition according to claim 1 , wherein the composition is in a form of a concentrate.

19 . An article having been treated with the composition of claim 1 .

20 . The article according to claim 19 , wherein the article is a textile material.

21 . A method for odor reduction and bacterial control on a textile material, the method comprising:
providing a composition comprising a GRAS additive or component having an antimicrobial or preservative property; and applying the composition to the textile material.

22 . The method according to claim 21 , further comprising an essential oil.

23 . The method according to claim 21 , wherein the GRAS additive is a minimum risk pesticide.

24 . The method according to claim 21 , wherein the GRAS additive is selected from the group consisting of sodium benzoate, potassium sorbate, and a combination thereof.

25 . The method according to claim 21 , wherein the GRAS additive is a food preservative.

26 . The method according to claim 21 , wherein the GRAS additive is an organic acid.

27 . The method according to claim 26 , wherein the organic acid is selected from the group consisting of benzoic acid, propionic acid, sorbic acid, citric acid, lactic acid, ascorbic acid, acetic acid, erythorbic acid, fumaric acid, malic acid, glycolic acid, a derivative thereof, and a combination thereof.

28 . The method according to claim 27 , wherein the organic acid is selected from the group consisting of benzoic acid, sorbic acid, citric acid, and a combination thereof.

29 . The method according to claim 22 , wherein the essential oil is selected from the group consisting of cedarwood oil, tea tree oil ( Melaleuca alternifolia ), eucalyptus oil ( Eucalyptus globulus or E. radiata ), clove oil ( Eugenia caryophyllata ), oregano oil ( Origanum vulgare ), thyme oil ( Thymus vulgaris ), geranium oil ( Pelargonium graveolens ), cinnamon bark oil ( Cinnamomum zeylanicum ), peppermint oil ( Mentha piperita ), lemongrass oil ( Cymbopogon flexuosus ), basil oil ( Ocimum basilicum ), lavender oil ( Lavandula angustifolia ), lemon oil ( Citrus limon ), rosemary oil ( Salvia rosmarinus ), bergamot oil ( Citrus bergamia ), perilla oil ( Perilla frutescens ), coriander oil ( Coriandrum sativum ), citron oil ( Citrus medica ), and a combination thereof.

30 . The method according to claim 21 , further comprising an odor mitigation compound.

31 . The method according to claim 30 , wherein the odor mitigation compound is selected from the group consisting of a metal oxide, activated carbon, sodium carbonate, calcium carbonate, zinc rincoleate, and a combination thereof.

32 . The method according to claim 21 , wherein the composition is in a form of a polymeric concentrate.
