1. A virucidally-enhanced alcoholic composition comprising: (a) at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic composition;(b) a first enhancer selected from the group consisting of polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquatern
1. A virucidally-enhanced alcoholic composition comprising: (a) at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic composition;(b) a first enhancer selected from the group consisting of polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-11, polyquaternium-16, polyquaternium-22, polyquaternium-28, polyquaternium-32, polyquaternium-37, polyquaternium-39, polyquaternium-42, polyquaternium-47, polyquaternium-51, polyquaternium-53, polyquaternium-55, polyquaternium-58, polyquaternium-68, and mixtures thereof; and(c) a second enhancer selected from the group consisting of citric acid, lactic acid, malic acid, tartaric acid, salicylic acid, oxalic acid, and mixtures thereof, wherein said enhancers are present in amounts that enhance the efficacy of the alcohol against non-enveloped viruses. 2. The composition of claim 1, wherein said composition comprises from about 0.015 to about 1 percent by weight of said second enhancer, based upon the total weight of the alcoholic composition. 3. The composition of claim 1, wherein said composition comprises from about 0.02 to about 20 percent by weight of said first enhancer, based upon the total weight of the alcoholic composition. 4. A virucidally-enhanced alcoholic composition comprising: (a) at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic composition;(b) a first enhancer selected from the group consisting of polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-11, polyquaternium-16, polyquaternium-22, polyquaternium-28, polyquaternium-32, polyquaternium-37, polyquaternium-39, polyquaternium-42, polyquaternium-47, polyquaternium-51, polyquaternium-53, polyquaternium-55, polyquaternium-58, polyquaternium-68, and mixtures thereof; and(c) a second enhancer selected from the group consisting of urea, thiourea, guanidine HCl, guanidine thiocyanate, aminoguanidine HCl, and mixtures thereof, wherein said enhancers are present in amounts that enhance the efficacy of the alcohol against non-enveloped viruses. 5. The composition of claim 4, wherein said composition comprises from about 0.25 to about 20 percent by weight of said second enhancer, based upon the total weight of the alcoholic composition. 6. The composition of claim 4, wherein said composition comprises from about 0.02 to about 20 percent by weight of said first enhancer, based upon the total weight of the alcoholic composition. 7. A virucidally-enhanced alcoholic composition comprising: (a) at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic composition;(b) a first enhancer selected from the group consisting of polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-11, polyquaternium-16, polyquaternium-22, polyquaternium-28, polyquaternium-32, polyquaternium-37, polyquaternium-39, polyquaternium-42, polyquaternium-47, polyquaternium-51, polyquaternium-53, polyquaternium-55, polyquaternium-58, polyquaternium-68, and mixtures thereof; and(c) a second enhancer selected from the group consisting of citric acid, lactic acid, malic acid, tartaric acid, salicylic acid, oxalic acid, urea, thiourea, guanidine HCl, guanidine thiocyanate, aminoguanidine HCl, and mixtures thereof, wherein said enhancers are present in amounts that enhance the efficacy of the alcohol against non-enveloped viruses.
