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 function 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 (24)

1. A cleaning composition, comprising:

a granular absorbent material coated with a biocide; and

a sanitation agent absorbed in said granular absorbent material,

wherein the granular absorbent material is not perlite, and

wherein the granular absorbent material constitutes 10-50% (w/w) of the cleaning composition.

2. The cleaning composition 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.

3. The cleaning composition of claim 1 , wherein the granular absorbent material comprises ceramic minerals.

4. The cleaning composition of claim 3 , wherein the ceramic minerals comprise perlite and/or vermiculite.

5. The cleaning composition 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, periodine and combinations thereof.

6. The cleaning composition 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.

7. The cleaning composition of claim 1 , further comprising:

a thickening agent, a gum, an absorbent polymer or combinations thereof.

8. The cleaning composition of claim 1 , further comprising a carboxymethyl cellulose (CMC)-derived polymer and/or a hierarchically porous carbons (HPC)-derived polymer.

9. A cleaning kit, comprising:

the cleaning composition of claim 1 , and

instructions on how to use the cleaning composition.

10. The cleaning kit of claim 9 , further comprising a copy of OSHA guidelines.

11. The cleaning kit of claim 9 , further comprising one or more items selected from the group consisting of biohazard bags, gloves, twist tie, antimicrobial hand wipe, germicidal wipe, scoops and scrapers.

12. The cleaning composition of claim 1 , wherein the granular absorbent material has a surface area per mass ratio up to 10,000 m 2 /g.

13. The cleaning composition of claim 1 , wherein the granular absorbent material constitutes 25-30% (w/w) of the cleaning composition.

14. The cleaning composition of claim 1 , wherein the granular absorbent material comprises vermiculite.

15. The cleaning composition of claim 1 , further comprising a super-absorbent polymer.

16. The cleaning composition of claim 1 , further comprising a modifying agent selected from the group consisting of a tackifier, a thickening agent, a gum, an absorbent polymer, a carboxymethyl cellulose (CMC)-derived polymer, a hierarchically porous carbons (HPC)-derived polymer, or a combination thereof,

wherein the cleaning composition comprises 0.5 to 3.5 wt % of the biocide, 0.1 to 10 wt % of the sanitation agent, and 0.1 to 5 wt % of the modifying agent.
