Abstract
Antibacterial compositions having enhanced antibacterial effectiveness are disclosed. The antibacterial compositions contain a phenolic antibacterial agent, a surfactant, and water, wherein a percent saturation of the antibacterial agent in a continuous aqueous phase of the composition is at least 50%.
Claims36
An antibacterial composition comprising:
- (a) about 0.001% to about 5%, by weight, of a phenolic antimicrobial agent;
- (b) about 0.1% to about 15%, by weight, of a surfactant selected from the group consisting of an anionic surfactant, a cationic surfactant, a nonionic surfactant, an ampholytic surfactant, and mixtures thereof;
- (c) 2% to about 30%, by weight, of a hydrotrope;
- (d) 2% to about 25%, by weight, of a water-soluble hydric solvent;
- and
- (e) water,
- wherein the antimicrobial agent is present in an amount of at least 40% of saturation concentration, when measured at room temperature.
