Abstract
Antibacterial compositions having enhanced antibacterial effectiveness are disclosed. The antibacterial compositions contain an antibacterial agent, an alkamine oxide, a nonionic and/or cationic cosurfactant, an optional polymeric thickener, and water.
Claims37
An antimicrobial composition comprising:
- (a) about 0.05% to about 5%, by weight, of a phenolic antibacterial agent;
- (b) about 1% to about 15%, by weight, of an alkamine oxide surfactant;
- (c) about 1% to about 10%, by weight, of (i) a nonionic cosurfactant selected from the group consisting of an ethoxylated alkylphenol, an ethoxylated fatty alcohol, a propoxylated fatty alcohol, an alkyl polyglucoside, a polyethylene glycol ether of sorbitol, an ethylene oxide-propylene oxide block copolymer, an ethoxylated ester of a fatty (C8-C14) acid, a condensation product of ethylene oxide with a long chain amine or amide, and mixtures thereof, (ii) a cationic cosurfactant, or (iii) a mixture thereof;
- (d) 0% to about 5%, by weight, of a polymeric thickener;
- and
- (e) water,
- wherein the antibacterial composition has a pH of about 5.5 to about 7.5, and is free of an anionic surfactant.
