Abstract: Quat-free surface treatment powders comprising a peroxide source, an acyl group donor and an alkalinity source are used to disinfect and/or sanitize hard surfaces. The surface treatment powders can be applied to a hard surface and left there for a period of time. The surface treatment powders are ambient moisture activated, which means that they can generate peracetic acid when a portion or all of the powder that is on the hard surface adsorbs water from the atmosphere. In addition or alternatively, the surface treatment powders are activated, i.e., generate peracetic acid through the incidental or purposeful addition of liquid thereto.

Abstract: Generation of foam when spraying biofilm-detection compositions onto a surface may entrain air and create bubbles, which lead to false positives. Aqueous biofilm-detecting compositions containing low-foaming surfactants, radical scavenger, solvent, thickener, hydrogen peroxide, chelating and coupling agent may be sprayed onto a surface to test for the presence of biofilm without generating excess bubbles or foam.

Abstract: Ambient moisture-activatable surface treatment powders containing persalt, positively charged phase transfer agent and alkaline pH buffering may be activatable without the addition of liquid. Some ambient moisture-activatable surface treatment powders are substantially free of bleach activators and/or chlorine. Methods of use of ambient moisture activatable powders include applying them to the surfaces to be treated.

Abstract: Alkaline in-use solutions that may be used to disinfect and/or sanitize hard surfaces and which may act as anti-biofilm agents, comprise a disinfectant/sanitizer cleaner solution and an activator solution that are mixed together to form the alkaline in-use solutions. Disinfectant/sanitizer cleaner solution may comprise quaternary ammonium compound and hydrogen peroxide. Activator solution may comprise alkaline buffering agent, chelating agent and soluble silicon dioxide.
