Abstract
An antimicrobial hydroalcoholic composition comprising hydroalcoholic solvent system comprising a lower alcohol and water in a weight ratio of at least about 50:50; a thickener system comprising at least one cationic or nonionic polymeric thickener that is solid at ambient temperature; and a secondary antimicrobial agent.
Claims50
An antimicrobial hydroalcoholic composition comprising:
- (a) a hydroalcoholic solvent system comprising a lower alcohol and water in a weight ratio of at least about 50:50;
- (b) a thickener system comprising at least one cationic polymeric thickener that is solid at ambient temperature;
- wherein the cationic thickener is selected such that the composition has a viscosity of at least about 10,000 centipoise at 23° C.;
- wherein the thickener system is present in an amount of at least about 0.5% by weight, based on the total weight of the composition,;
- and
- (c) a secondary antimicrobial agent.

An antimicrobial hydroalcoholic lotion comprising:
- (a) a hydroalcoholic solvent system comprising a lower alcohol and water in a weight ratio of at least about 60:40;
- (b) a thickener system consisting essentially of one or more nonionic polymeric thickeners, at least one of which is solid at ambient temperature;
- wherein the one or more polymeric thickeners are selected such that the composition has a viscosity of at least about 4,000 centipoise at 23° C.;
- and further wherein the thickener system is present in an amount of at least about 0.5% by weight, based on the total weight of the composition, and
- (c) a secondary antimicrobial agent.
