Abstract

The present invention relates to novel combined laundry detergent, bleach, and antimicrobial composition incorporating novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds used in compositions of the invention are storage stable, water soluble and have low to no odor. Compositions of the invention may be in the form of a liquid, a solid, or a gel. The sulfoperoxycarboxylic compounds useful in preparing compositions of the present invention can be formed from non-petroleum based renewable materials.

First claim

The invention claimed is:

1. A laundry composition, comprising:
(a) one or more sulfoperoxycarboxylic acids, wherein said sulfoperoxycarboxylic acids comprise at least one of the following:

or salts thereof; or

or salts thereof;
(b) an oxidizing agent; (C) a C1 to C11 carboxylic acid; (d) a surfactant; (e) a stabilizing agent.

2. The composition of claim 1 further comprising a viscosity reducer.

3. The composition of claim 1 further comprising a defoamer.

4. The composition of claim 3 wherein the defoamer is an alkyl alkoxylate containing in part or whole poly-propylene oxide units.

5. The composition of claim 1 wherein the composition is a liquid, gel or solid.

6. The composition of claim 1 , wherein said one or more sulfoperoxycarboxylic acids further comprise:

salts, esters, mixtures or derivatives thereof.

7. The composition of claim 1 , wherein the pH of the composition is less than about 7.

8. The composition of claim 1 , wherein the sulfoperoxycarboxylic acids are present at about 0.05 wt % to about 50 wt %.

9. The composition of claim 1 , wherein, the sulfoperoxycarboxylic acids are present at about 0.05 wt % to about 30 wt %.

10. The composition of claim 1 , wherein the sulfoperoxycarboxylic acids are present at about 1.0 wt % to about 20 wt %.

11. The composition of claim 1 , wherein the oxidizing agent is selected from the group consisting of hydrogen peroxide, an organic peracid, an organic peroxide, and combinations thereof.

12. The composition of claim 1 , wherein the carboxylic acid comprises octanoic acid.

13. The composition of claim 12 , wherein the composition further comprises a C 2 to C 11 peroxycarboxylic acid.

14. The composition of claim 13 , wherein the peroxycarboxylic acid comprises peroxyoctanoic acid, peroxynonanoic acid, peroxydecanoic acid, or combinations thereof.

15. The composition of claim 14 , wherein the peroxycarboxylic acid is present at about 0.1 wt % to about 10 wt %.

16. The composition of claim 13 , wherein the peroxycarboxylic acid is selected from the group consisting of peroxyacids of acetic, glycolic, butyric, hexanoic, heptanoic, salicylic, malic, mandelic, malonic, succinic, glutaric, adipic, and citric acids, and mixtures thereof.

17. The composition of claim 1 , wherein the stabilizing agent is selected from the group consisting of organic amino polyphosphonic acid complexing agents, organic hydroxyl polyphosphonic acid complexing agents, and mixtures thereof.

18. The composition of claim 1 , wherein the composition is substantially phosphorous free.

19. The composition of claim 1 , wherein the composition comprises:
(a) about 0.05 wt % to about 50 wt % of the one or more sulfoperoxycarboxylic acids;
(b) about 0.1 wt % to about 75 wt % of the oxidizing agent;
(c) about 0.1 wt % to about 40 wt % of the C 1 -C 11 carboxylic acid in combination with one C 1 to C 22 peroxycarboxylic acid;
(d) about 0.50 wt % to about 70 wt % of the surfactant;
(e) about 0.0 wt % to about 5 wt % of an additional acidulant;
(f) about 0.0 to about 10 wt % of a viscosity reducer.

20. The composition of claim 2 wherein the viscosity reducer is comprised of propylene glycol.

21. The composition of claim 1 wherein the surfactant is selected from the group consisting of nonionic surfactant, anionic surfactant, amine oxide surfactant, and mixtures thereof.

22. The composition of claim 19 wherein the acidulant (e) is selected from the group consisting of sulfuric acid, methane sulfonic acid, ethane sulfonic acid, propane sulfonic acid, butane sulfonic acid, xylene sulfonic acid, benzene sulfonic acid, linear alkyl benzene sulphonic acid, cumene sulfonic acid, xylene sulfonic acid, and combinations thereof.

23. The composition of claim 21 wherein the anionic surfactant is selected from the group consisting of linear alkyl benzene sulphonate, linear alkyl benzene sulfonic acid, and mixtures thereof.
