Cleaning composition, method of making and use thereof
A method for formulating a cleaning composition contains the step of coating a granular absorbent material with a coating agent to produce a coated absorbent material and mixing the coated absorbent material with a sanitation agent, wherein the coated absorbent material absorbs the sanitation agent to form the cleaning composition. The resulting cleaning composition may be used for cleaning up pathogens or hazardous materials. The cleaning composition may also functions as a liquefiable dry cleaning powder for public areas in response to bodily fluid incidents. A coating method of a non-toxic bio static film on a high surface area solid is disclosed.
1. A method of formulating a cleaning composition, comprising the steps of:
(a) grinding an absorbent material to produce a granular absorbent material, wherein the granular absorbent material constitutes 10-50% (w/w) of the cleaning composition or wherein the granular absorbent material does not comprise perlite;
(b) coating the granular absorbent material with a biocide to produce a coated absorbent material, wherein the coating agent forms a surface bonded film on the granular absorbent material; and
(c) mixing the coated absorbent material with a sanitation agent so that the coated absorbent material absorbs the sanitation agent to form the cleaning composition.
2. The method of claim 1 , wherein the biocide is selected from the group consisting of silanes, siloxanes, aminopropyltrimethoxysilane, quaternary amines, fumed metal hydroxides, solutions of silver, solutions of copper and combinations thereof.
3. The method of claim 1 , wherein the biocide is a liquid phase biocide.
4. The method of claim 3 , wherein the liquid phase biocide comprises one or more members selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solutions, peracetic acid, quaternary amine solutions, alcohol solutions, periodine solutions, dimethyl benzyl ammonium chloride, dimethyl ethybenzyl ammonium chloride and mixtures thereof.
5. The method of claim 1 , wherein the biocide is applied to granular absorbent material by vapor deposition, by a pressure micro droplet spray, or by a fuming or fogging nozzle.
6. The method of claim 1 , wherein the granular absorbent material has a surface area per mass ratio of 1,000 m 2 /g or greater.
7. The method of claim 1 , wherein the granular absorbent material has a surface area per volume ratio of 1,000 m 2 /ml or greater.
8. The method of claim 1 , wherein the sanitation agent is selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solution, peracetic acid, quaternary amine solutions, alcohol solutions and combinations thereof.
9. The method of claim 1 , wherein the sanitation agent constitutes 0.1 to 10% (w/w) of the cleaning composition.
10. The method of claim 1 , wherein the biocide forms a surface bonded film on the granular absorbent material.
11. The method of claim 1 , wherein the biocide constitutes 0.5 to 3.5% (w/w) of the cleaning composition.
12. A method of using a cleaning composition, comprising:
applying an effective amount of the cleaning composition of claim 1 to a surface in need of cleaning so as to form a treated surface; and
removing the cleaning composition.
13. The method of claim 12 , further comprising the step of washing the treated surface with a liquid or wiping the surface with a wiping material after the removal of the cleaning composition.
14. The method of claim 12 , wherein the cleaning composition is removed after treating the surface for a period of time between 30 seconds to 30 minutes.
15. The method of claim 12 , wherein the surface in need of cleaning is in a public area.
16. The method of claim 12 , the surface in need of cleaning comprises a biohazard spill.
17. The method of claim 1 , wherein the granular absorbent material constitutes 10-50% (w/w) of the cleaning composition.
18. The method of claim 1 , wherein the granular absorbent material does not comprise perlite.
19. The method of claim 1 , wherein the granular absorbent material comprises vermiculite.
