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.
Claims16
An ambient moisture-activatable had surface treatment powder consisting essentially of, by weight percentage of the surface treatment powder:
- (a) from about 5% to about 10% sodium carbonate;
- (b) from about 15% to about 90% sodium bicarbonate;
- (c) from about 10% to about 40% sodium percarbonate;
- (b) from about 1% to about 10% quaternary ammonium salt;
- (c) from about 2% to about 5% EDTA;
- and
- (e) from about 0.1% to about 4% polyethylene glycol.
A method of treating a hard surface, the method comprising applying to the hard surface an ambient moisture-activatable surface treatment powder consisting essentially of, by weight percentage of the surface treatment powder:
- (a) from about 5% to about 49% of percarbonate salt;
- (b) from about 0.5% to about 30% quaternary ammonium salt;
- (c) from about 15% to less than about 90% monocationic carbonate salt;
- (d) from about 0.5% to about 15% chelating agent;
- (e) from about 0.1% to about 10% glycol;
- and
- (f) colorant.
A method of treating a hard surface, the method comprising applying to the hard surface an ambient moisture-activatable surface treatment powder comprising, by weight percentage of the hard surface treatment powder:
- (a) from about 5% to about 10% sodium carbonate;
- (b) from about 15% to about 90% sodium bicarbonate;
- (c) from about 10% to about 40% sodium percarbonate;
- (b) from about 1% to about 10% quaternary ammonium salt;
- (c) from about 2% to about 5% EDTA;
- and
- (e) from about 0.1% to about 4% polyethylene glycol.
