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.
