Abstract
A disinfectant composition that is capable of inactivating non-enveloped viruses as well as other microorganisms, such as gram negative and gram positive bacteria, fungi, parasites, enveloped viruses, etc., is provided. Through selective control over the nature of the acid(s) employed and the overall pH level, the present inventors have discovered that the composition can achieve rapid antiviral efficacy, particularly against non-enveloped viruses. Once applied to a surface (e.g., hard surface), the disinfectant composition forms a film that remains capable of providing residual antiviral activity. Notably, the present inventors have discovered that the use of a vinylpyrrolidone copolymer in combination with a polyquaternary ammonium polymer and cationic surfactant can have a synergistic effect on the stability of the film such that it can also achieve long-term, residual antiviral activity.
