Abstract
An antimicrobial composition containing a diluent (e.g. water) and about 0.01 wt. % to about 90 wt. % of at least one compound according to Formula 1 wherein R1 is a branched or unbranched, saturated or unsaturated, C3 to C5 N-alkyl-chain and the antimicrobial composition is substantially free of peroxygen compounds, antibiotics, and chloroacetamide. Methods of using the composition to reduce the microbial load on a surface are also provided, as is the use of the compound according to Formula 1 as an antimicrobial agent.
Claims21
A ready-to-use antimicrobial composition comprising:
- (a) a synergistic combination of antimicrobial agents, and (b) a diluent, wherein the antimicrobial agents in the antimicrobial composition consist of:
- (i) about 0.5 wt. % to about 16 wt. % of a first antimicrobial agent consisting of at least one compound according to Formula 1:
- wherein R1 is a branched or unbranched, saturated or unsaturated, unsubstituted C3 to C5 alkyl chain or a C3 alkyl chain substituted with a methoxy group;
- (ii) an effective amount of at least 0.05 wt. % to about 15 wt. % of at least one second antimicrobial agent selected from the group consisting of salicylic acid, 2-furoic acid, mandelic acid, acetic acid, dimethylol propionic acid, gallic acid, malic acid, lactic acid, and salts thereof;
- and
- (iii) optionally, an effective amount of at least one additional antimicrobial agent selected from the group consisting of carboxylic acids and salts thereof other than those in (ii), alcohols, anionic surfactants, amphoteric surfactants, quaternary ammonium compounds, phenols, aldehydes, biguanides, mineral acids, glycerol ethers, antimicrobial solvents, and antimicrobial metals;
- wherein the diluent is present at q.s. to 100;
- and
- wherein the antimicrobial composition is substantially free of peroxygen compounds, antibiotics, N-methyl pyrrolidone (NMP), N-ethyl pyrrolidone (NEP), and chloroacetamide.
A concentrated antimicrobial composition which, when combined with an effective amount of water, provides a ready-to-use composition comprising:
- (a) a synergistic combination of antimicrobial agents, wherein the antimicrobial agents consist of:
- (i) about 0.5 wt. % to about 16 wt. % of a first antimicrobial agent consisting of at least one compound according to Formula 1:
- wherein R1 is a branched or unbranched, saturated or unsaturated, unsubstituted C3 to C5 alkyl chain or a C3 alkyl chain substituted with a methoxy group;
- (ii) an effective amount of at least 0.05 wt. % to about 15 wt. % of at least one second antimicrobial agent selected from the group consisting of salicylic acid, 2-furoic acid, mandelic acid, acetic acid, dimethylol propionic acid, gallic acid, malic acid, lactic acid, and salts thereof;
- and
- (iii) optionally, an effective amount of at least one additional antimicrobial agent selected from the group consisting of carboxylic acids and salts thereof other than those in (ii), alcohols, anionic surfactants, amphoteric surfactants, quaternary ammonium compounds, phenols, aldehydes, biguanides, mineral acids, glycerol ethers, antimicrobial solvents, and antimicrobial metals;
- and
- (b) water q.s. to 100;
- wherein the antimicrobial composition is substantially free of peroxygen compounds, antibiotics, N-methyl pyrrolidone (NMP), N-ethyl pyrrolidone (NEP), and chloroacetamide.
