Abstract

An antimicrobial composition is provided that comprises about 10.0 to about 40.0 wt. % of one or more C 1-8 alcohols, based on the total weight of the antimicrobial composition; and two or more of a surfactant; an enhancer; and a buffer. The pH of the composition is less than or equal to about 6.0 and the composition achieves a microbial log reduction of greater than 4.0 log CFU/ml at a contact time of 1 minute, in accordance ASTM E2783.

Claims (41)

1. An antimicrobial composition comprising:

from greater than 15 to less than 25 wt. % collectively of a C 1-8 alcohol;

from 0.5 to 2 wt. % of a surfactant comprising an alkyl polyglucoside;

an enhancer comprising sodium benzoate; and

a buffer comprising citric acid or a salt thereof,

wherein the total concentration of the buffer and the enhancer collectively is from 1 to 3 wt. %, based on the total weight of the antimicrobial composition,

wherein the pH of the antimicrobial composition is less than 5,

wherein the antimicrobial composition is devoid of peroxide,

wherein the antimicrobial composition achieves a microbial log reduction of greater than 4.0 log CFU/ml at a contact time of 1 minute, in accordance with ASTM E2783, and

wherein each wt. % is based on the total weight of the antimicrobial composition.

2. The antimicrobial composition of claim 1 , wherein the composition comprises from 18 to 22 wt. % collectively of the C 1-8 alcohol, based on the total weight of the antimicrobial composition.

3. The antimicrobial composition of claim 1 , wherein the antimicrobial composition has a pH of from 1.5 to 4.5 .

4. The antimicrobial composition of claim 1 , wherein the antimicrobial composition comprises from 0.5 to 2 wt. % of the buffer, based on the total weight of the antimicrobial composition.

5. The antimicrobial composition of claim 1 , wherein the antimicrobial composition comprises from 0.1 to 0.4 wt. % of the enhancer, based on the total weight of the antimicrobial composition.

6. A wipe comprising the antimicrobial composition of claim 1 .

7. An antimicrobial composition comprising:

from greater than 15 to less than 25 wt. % collectively of a C 1-8 alcohol;

from 0.5 to 2 wt. % of a surfactant comprising an alkyl polyglucoside;

an enhancer comprising a salt of an aromatic acid; and

from 0.5 to 2 wt. % of a buffer, the buffer comprising an organic acid, an inorganic acid, salts thereof, or combinations thereof,

wherein the total concentration of the buffer and the enhancer collectively is from 1 to 3 wt. %,

wherein the pH of the antimicrobial composition is less than 5,

wherein the antimicrobial composition is devoid of peroxide,

wherein the antimicrobial composition achieves a microbial log reduction of greater than 4.0 log CFU/ml at a contact time of 1 minute, in accordance with ASTM E2783, and

wherein each wt. % is based on the total weight of the antimicrobial composition.

8. The antimicrobial composition of claim 7 , wherein the composition comprises from 18 to 22 wt. % collectively of the C 1-8 alcohol, based on the total weight of the antimicrobial composition.

9. The antimicrobial composition of claim 7 , wherein the antimicrobial composition has a pH of from 1.5 to 4.5.

10. The antimicrobial composition of claim 7 , wherein the antimicrobial composition comprises from 0.1 to 0.4 wt. % of the enhancer, based on the total weight of the antimicrobial composition.

11. A wipe comprising the antimicrobial composition of claim 7 .

12. An antimicrobial composition consisting of:

from greater than 15 to less than 25 wt. % collectively of a C 1-8 alcohol, based on the total weight of the antimicrobial composition;

a non-ionic surfactant consisting of alkyl polyglucoside;

an enhancer consisting of a salt of an aromatic acid;

a buffer selected from the group consisting of an organic acid, an inorganic acid, salts thereof, or combinations thereof; and

water,

wherein the pH of the antimicrobial composition is less than 5, and

wherein the antimicrobial composition achieves a microbial log reduction of greater than 4.0 log CFU/ml at a contact time of 1 minute, in accordance with ASTM E2783.

13. The antimicrobial composition of claim 12 , wherein the total concentration of the buffer and the enhancer collectively is from 1 to 3 wt. %, based on the total weight of the antimicrobial composition.

14. The antimicrobial composition of claim 12 , wherein the buffer is present in an amount from 0.5 to 2 wt. %, based on the total weight of the antimicrobial composition.

15. The antimicrobial composition of claim 12 , wherein the enhancer is present in an amount from 0.1 to 0.4 wt. %, based on the total weight of the antimicrobial composition.

16. A wipe comprising the antimicrobial composition of claim 12 .
