Abstract: An aqueous-based disinfecting composition is disclosed. The composition can include hydrogen peroxide at a concentration of 0.1 to 0.9% w/w, caprylic acid, or a salt thereof, at a concentration of 0.1 to 1% w/w, salicylic acid, or a salt thereof at a concentration of 0.1 to 1% w/w, and water. The composition does not include or is substantially free of a volatile C1-C7 alcohol, and the pH of the composition is from about 0.1 to about 6, and the composition is capable of exhibiting mycobactericidal activity against mycobacteria on a surface when the composition is in contact with the mycobacteria for at least 1 minute.

Abstract: Disclosed are low-level hydrogen peroxide aqueous-based disinfectant compositions that are substantially free of or do not contain volatile short chain (C1-C7) alcohols and exhibit broad spectrum antimicrobial/microbicidal activity against a variety of microorganisms including mycobacteria. Also disclosed are methods for using the compositions for the disinfection or sterilization of a variety hard surfaces such as those found in dental, hospital, and clinical environments or in food preparation environments.
