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 (16)

1. A method of formulating a cleaning composition to decontaminate surfaces contaminated by a virus, 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, wherein the sanitation agent comprises a surfactant,

wherein the surface is contaminated by the virus selected from the group consisting of norovirus and hepatitis virus.

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 ceramic minerals comprise perlite and/or vermiculite.

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

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

8. The method of claim 1 , wherein the sanitation agent is an anionic surfactant.

9. A method of formulating a cleaning composition to decontaminate surfaces contaminated by a virus, 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, wherein the sanitation agent comprises a surfactant,

wherein the virus is SARS-COV-2.
