Cleaning and disinfectant compositions
View Patent ↗Cleaning and disinfectant compositions are provided particularly for use with hard surfaces. The compositions include hydrogen peroxide and an acid or salt thereof which is resistant to oxidation other than phosphorous based acids. Replacement of phosphorous based acids with acids of the invention results in improved hydrogen peroxide stability while maintaining or increasing the efficacy of cleaning and antimicrobial activity of the compositions. Typically, acids of the invention include substituted or unsubstituted carboxylic acids such as R 4 —C (R 2 ) (R 3 ) —R 1 —COOH. Inventive compositions may further include surfactants, a chelating agent or sequestrant, a water soluble or water dispersible solvent, corrosion inhibitors and other adjuvants well known to those skilled in the art. There are further provided methods of use and methods of preparing inventive compositions.
1. A composition comprising:
hydrogen peroxide;
1-hydroxyethylene-1,1-diphosphonic acid;
at least one anionic surfactant; and
an acid selected from neononanoic acid and neodecanoic acid.
2. The composition of claim 1 further comprising a solvent.
3. The composition of claim 2 wherein the solvent is propylene glycol propyl ether, ethylene glycol butyl ether, ethylene glycol n-hexyl ether, propylene glycol methyl ether, hexylene glycol ethyl ether, propylene glycol butyl ether, carbitol, alcohols, or a mixture of two or more thereof.
4. The composition of claim 1 further comprising a nonionic, cationic or amphoteric surfactant.
5. The composition of claim 4 wherein the surfactant is an alkyl phenoxypolyethoxy ethanol, a polyoxyethylene, an amine oxide, a multi block copolymer, a phosphate ester, an ethoxylated carboxylate, or a mixture of two or more thereof.
6. The composition of claim 1 further comprising a chelating agent or sequestrant.
7. The composition of claim 6 wherein the chelating agent or sequestrant is N-(hydroxyethyl)ethylenediamine triacetic acid, a sucrose sequestrant, or sodium acid pyrophosphate/1,3-diamino-2-hydroxypropane-4N-tetraacetic acid.
8. A composition comprising
8 wt % hydrogen peroxide;
8 wt % 1-hydroxyethylene-1,1-diphosphonic acid;
5 wt % of an acid selected from neononanoic acid and neodecanoic acid;
3 wt % of a nonionic surfactant;
0.1 wt % of a chelating agent or sequestrant; and
8 wt % of a solvent that is water soluble or water dispersible.
9. The composition of claim 8 further comprising 8 wt % of an anionic surfactant.
10. A method of cleaning and disinfecting a surface comprising applying a composition of claim 1 to the surface.
11. The method of claim 10 further comprising diluting the composition with water prior to applying it to the surface.
12. A method of making the composition of claim 1 comprising combining the hydrogen peroxide, the 1-hydroxyethylene-1,1-diphosphonic acid, at least one anionic surfactant, and the acid selected from neononanoic acid and neodecanoic acid.
13. The composition of claim 1 wherein the composition is contained on a pre-saturated wipe.
14. The composition of claim 13 wherein the wipe consists of a non-woven product.
15. The composition of claim 13 wherein the wipe consists of a disposable paper product.
16. The composition of claim 13 wherein the wipe consists of a fabric.
17. The composition of claim 1 , wherein at least one anionic surfactant is an alkyl aryl sulfonic acid.
