Abstract:
1. An antimicrobial hydroalcoholic composition comprising: (a) a hydroalcoholic solvent system comprising a C1-C4 alcohol and water in a weight ratio of C1-C4 alcohol to water of at least 60:40; wherein the C1-C4 alcohol is present in the composition in an amount of at least 60% by weight, based on the total weight of the composition; (b) a thickener system consisting essentially of at least one associative polymeric thickener that is solid at ambient temperature, is cationic or nonionic, thickens the hydroalcoholic solvent system, and comprises greater than two hydrophobic chains of greater than 16 carbon atoms per polymer molecule; wherein the associative polymeric thickener has a number average molecular weight of at least 20,000; wherein the thickener system is present in an amount of at least 0.5% by weight, based on the total weight of the composition; and (c) a secondary antimicrobial agent.
