Aqueous mycobacterial composition and hard surface disinfecting composition

摘要

Disclosed are aqueous mycobacterial concentrate compositions at a pH in the range of 6 to 12 which comprises per 100% weight of a concentrate composition: a) from about 0.1% wt. to about 25% wt. of a germicidal cationic quaternary ammonium compound; b) from about 0.25% wt. to about 25% wt. of a solvent selected from: phenoxyalcohol, glycol ethers, or mixtures thereof; and, c) water. The concentrate compositions may be used in a ready to use form, or may be further diluted with water to form a disinfecting composition. The compositions may also include an effective amount of a pH adjusting agent, such as sodium hydroxide or triethanolamine. The compositions feature reduced amounts of active constituents when compared with those known to the art. They are particularly effective against Mycobacteriuin terrae. Also disclosed is a method of disinfecting a hard surface.
