Abstract

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.

Claims

1. A method of formulating a cleaning composition, comprising the steps 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.

2. The method of claim 1, further comprising the step of:

grinding an absorbent material to produce the granular absorbent material used in the coating step.

3. The method of claim 1, wherein the granular absorbent material is coated with a layer of surface bonded biocide by vapor deposition, pressure micro droplet spray or fuming or fogging nozzle.

4. The method of claim 1, wherein the granular absorbent material is selected from the group consisting of ceramic minerals, zeolite, activated carbon, fumed silica, processed clays, cellulosic absorbents, fibrous absorbents and combinations thereof.

5. The method of claim 4, wherein the granular absorbent material comprises ceramic minerals.

6. The method of claim 5, wherein the ceramic minerals comprise perlite and/or vermiculite.

7. The method of claim 1, wherein the coating agent comprises a biocide.

8. The method of claim 7, 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.

9. The method of claim 1, wherein the coating agent forms a surface bonded film on the granular absorbent material.

10. The method of claim 1, wherein the sanitation agent is a liquid.

11. The method of claim 1, wherein the sanitation agent is selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solution, per acetic acid, quaternary amine solutions, alcohol solutions and combinations thereof.

12. The method of claim 1, wherein the cleaning composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition.

13. The method of claim 1, further comprising the step of:

adding a modifying agent to the cleaning composition in an amount sufficient to achieve desired physical characteristics the cleaning composition.

14. The method of claim 13, wherein the modifying agent comprises a thickening agent, a gum, a absorbent polymer or combinations thereof.

15. The method of claim 13, wherein the modifying agent comprises a carboxymethyl cellulose (CMC)-derived polymer and/or a hierarchically porous carbons (HPC)-derived polymer.

16. A method for prevention and/or decontamination of a surface from a pathogen, comprising:

applying an effective amount of cleaning composition on said surface, wherein said cleaning composition comprises an granular absorbent material coated with a biocide; and

a sanitation agent absorbed in said granular absorbent material.

17. The method of claim 16, wherein said pathogen is a virus, bacteria, fungus or protozoa.

18. The method of claim 17, said virus is norovirus, HIV, rotavirus, adenovirus, astrovirus, coronavirus, hepatitis virus, ebola or norovirus, arenaviruses, bunyaviruses, filoviruses, arenaviruses, Nipah virus or hantavirus.

19. The method of claim 17, said bacteria is Campylobacter, Escherichia, Salmonella, Shigella, Staphylococcus aureus, or Clostridum species.

20. The method of claim 17, said protozoa is Giardia, Entamoeba or Cryptosporidium species.

21. The method of claim 17, said fungus is Aspergillus, Blastomyces, Candida, Coccidioides, Cryptococcus, Fusarium, Histoplasma or Pneumocystis species.

22. A cleaning composition, comprising:

an granular absorbent material coated with a biocide; and

a sanitation agent absorbed in said granular absorbent material.

23. The cleaning composition of claim 22, wherein the granular absorbent material is selected from the group consisting of ceramic minerals, zeolite, activated carbon, fumed silica, processed clays, cellulosic absorbents, fibrous absorbents and combinations thereof.
