Abstract
Antimicrobial compositions having an excellent antibacterial and antiviral effectiveness are disclosed. The antimicrobial compositions contain an aromatic carboxylic acid, a hydric solvent, a pH-adjusting compound, and water.
Claims21
A method of reducing a bacteria population on a surface comprising contacting the surface with an antimicrobial composition for 30 seconds to achieve a log reduction of at least 3 against S. aureus or a log reduction of at least 3 against E. coli, wherein the antimicrobial composition comprises:
- (a) about 0.1% to about 10%, by weight, of an aromatic carboxylic acid, wherein the aromatic carboxylic acid has a structure
- wherein R, independently, is selected from the group consisting of hydroxy, C1-4alkyl, C1-4alkoxy, amino, halo, phenyl, and benzyl;
- and n is 1 or 2;
- (b) about 10% to about 40%, by weight, of a hydric solvent comprising dipropylene glycol;
- (c) a sufficient amount of a pH-adjusting compound to provide a pH of about 2 to about 5.5;
- and
- (d) a carrier comprising water,
- wherein the aromatic carboxylic acid is the sole antimicrobial agent in the composition,
- and the composition contains 0% to 0.2%, by weight, of a surfactant.
A method of reducing a viral population on a surface comprising contacting the surface with a composition of for 30 seconds to achieve a viral log reduction of at least 3,
- wherein the composition comprises:
- (a) about 0.1% to about boo, by weight, of an aromatic carboxylic acid, wherein the aromatic carboxylic acid has a structure
- wherein R, independently, is selected from the group consisting of hydroxy, C1-4alkyl, C1-4alkoxy, amino, halo, phenyl, and benzyl;
- and n is 1 or 2;
- (b) about 10% to about 40%, by weight, of a hydric solvent comprising dipropylene glycol;
- (c) a sufficient amount of a pH-adjusting compound to provide a pH of about 2 to about 5.5;
- and
- (d) a carrier comprising water,
- wherein the aromatic carboxylic acid is the sole antimicrobial agent in the composition,
- and the composition contains 0% to 0.2%, by weight, of a surfactant.
