Abstract

In one embodiment, a disinfectant composition includes a peroxide, a peracid, an anionic surfactant, a nonionic polymer, and one or both of a linear fatty alcohol and an alkyl pyrrolidone. The disinfectants provide greater killing rates for microbial populations in short periods of time, and therefore can be considered to be fast-acting disinfectants.
