Ambient moisture-activated hard surface treatment powder comprising a bicarbonate/carbonate/percarbonate mixture
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.
1. A hard surface treatment powder comprising:
(a) from about 5% to less than about 50% by weight of the surface treatment powder of persalt;
(b) from about 5% to about 10% sodium carbonate;
(c) from about 20.5% to about 90% of sodium bicarbonate;
(d) quaternary ammonium salt; and
(e) alkaline buffering agent selected from the group of bicarbonate salt, carbonate salt and combinations thereof;
the hard surface treatment powder comprising particles,
over about 65% of the particles ranging in size of from about 125 microns to about 250 microns; and
the hard surface treatment powder being substantially free of anionic surfactant.
2. The hard surface treatment powder of claim 1 , comprising by weight percentage of the hard surface treatment powder:
(a) from about 5% to about 10% sodium carbonate; and
(b) from about 21% to about 90% of sodium bicarbonate.
3. The hard surface treatment powder of claim 1 , comprising by weight percentage of the hard surface treatment powder:
(a) from about 5% to about 10% sodium carbonate; and
(b) from about 22.5% to about 90% of sodium bicarbonate.
4. The hard surface treatment powder of claim 1 , comprising by weight percentage of the hard surface treatment powder:
(a) from about 5% to about 10% sodium carbonate; and
(b) from about 25% to about 90% of sodium bicarbonate.
5. The hard surface treatment powder of claim 1 , comprising from about 5% to about 40% by weight of the surface treatment powder of persalt.
6. The hard surface treatment powder of claim 1 , further comprising glycol.
7. The hard surface treatment powder of claim 1 , further comprising by weight percentage of the hard surface treatment powder, from about 0.5 to about 2% glycol.
8. The hard surface treatment powder of claim 7 , wherein the glycol is polyethylene glycol.
