Peroxycarboxylic acid compositions with reduced odor
View Patent ↗The present invention relates to compositions of peroxycarboxylic acid that have reduced odor compared to conventional peroxycarboxylic acid compositions, methods employing these reduced-odor compositions, and methods of making these compositions. Typically, the reduced-odor compositions include an amine oxide surfactant.
1. A method of reducing population of microorganism on an object, comprising:
contacting the object with a reduced-odor peroxycarboxylic acid composition;
the composition comprising:
peroxycarboxylic acid; and
amine oxide;
the amine oxide being effective for reducing the odor of the peroxycarboxylic acid;
wherein the composition comprises 2 to 5 moles of amine oxide per mole of peroxycarboxylic acid.
2. The method of claim 1 , wherein the object comprises a food product, a food processing surface, a health care surface, a plant product, a body or stream of water, a body or stream of gas, a hospitality sector surface, an industrial sector surface, an agricultural surface, a veterinary surface, or a combination thereof.
3. The method of claim 1 , wherein the object comprises a hard surface.
4. The method of claim 1 , wherein the object comprises an air stream.
5. The method of claim 1 , wherein the object comprises an elastomer, a plastic, a woven substrate, a non-woven substrate, or a combination thereof.
6. The method of claim 1 , wherein contacting comprises spraying the composition, immersing the object in the composition, foam or gel treating the object with the composition, or a combination thereof.
7. The method of claim 1 , wherein the amine oxide comprises octyldimethylamine oxide, lauryldimethylamine oxide, or a mixture thereof.
8. The method of claim 1 , wherein the amine oxide comprises alkyldimethylamine oxide, dialkylmethylamine oxide, alkyldialkoxylamine oxide, dialkylalkoxyamine oxide, dialkyletheramine oxide and dialkoxyetheramine oxide.
9. The method of claim 1 , wherein the amine oxide has a formula of (R 1 R 2 R 3 )NO and wherein R 1 , R 2 , and R 3 are alkyl groups.
10. The method of claim 9 , wherein the R 1 alkyl group has about 4 to 18 carbon atoms.
11. The method of claim 9 , wherein the R 1 alkyl group has about 6 to 8 carbon atoms.
12. The method of claim 11 , wherein the R 2 and R 3 alkyl groups have 1 to 2 carbon atoms.
13. The method of claim 1 , wherein the mole ratio of amine oxide to peroxycarboxylic acid is greater than 3.
14. The method of claim 1 , wherein the peroxycarboxylic acid comprises peroxyacetic acid and the composition further comprises acetic acid.
15. The method of claim 1 , wherein the peroxycarboxylic acid comprises peroxyformic acid, peroxyacetic acid, peroxypropionic acid, peroxybutyric acid, peroxypentanoic acid, or mixture thereof.
16. A method of reducing population of microorganism on an object, comprising:
contacting the object with a reduced-odor peroxycarboxylic acid composition;
the composition comprising:
peroxyacetic acid; and
octyl dimethyl amine oxide or octyl diethyl amine oxide;
the amine oxide being effective for reducing the odor of the peroxycarboxylic acid;
mole ratio of amine oxide to peroxycarboxylic acid being 2 to 5.
