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 (19)

1. A method for decontaminating a surface from a pathogen, comprising:

applying a liquid cleaning composition to a surface in an amount sufficient to decontaminate the surface from the pathogen,

wherein said liquid cleaning composition comprises:

a granular absorbent material coated with a silane;

at least two sanitation agents comprising dimethyl benzyl ammonium chloride at a concentration between 1 to 10% (w/w) and dimethyl ethyl benzyl ammonium chloride at a concentration between 1 to 10% (w/w); and

sodium polyacrylate at a concentration between 1 to 5% (w/w),

wherein the granular absorbent material comprises perlite, and wherein the granular absorbent material constitutes 30-60% (w/w) of the liquid cleaning composition.

2. The method of claim 1 , wherein said pathogen is a virus, bacteria, fungus or protozoa.

3. The method of claim 2 , wherein said virus is a norovirus, HIV, rotavirus, adenovirus, astrovirus, coronavirus, hepatitis virus, Ebola virus bunyavirus, filovirus, arenavirus, Nipah virus or hantavirus.

4. The method of claim 2 , wherein said bacteria is Campylobacter, Escherichia, Salmonella, Shigella, Staphylococcus aureus , or Clostridium species.

5. The method of claim 2 , wherein said protozoa is Giardia, Entamoeba or Cryptosporidium species.

6. The method of claim 2 , wherein said fungus is Aspergillus, Blastomyces, Candida, Coccidioides, Cryptococcus, Fusarium, Histoplasma or Pneumocystis species.

7. A sanitation method, comprising the step of:

applying an effective amount of the liquid cleaning composition of claim 1 to a surface in need of sanitation; and

removing the cleaning composition after a period of time.

8. The method of claim 7 , wherein the surface in need of sanitation comprises a biohazard spill.

9. The method of claim 8 , wherein the biohazard spill is vomit, urine, blood, feces, and/or a chemo therapy drug.

10. The method of claim 7 , further comprising the step of:

washing the surface with a liquid or wiping the surface with a wiper after the removal of the cleaning composition.
