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

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

grinding an absorbent material to produce a granular absorbent material used in a coating step;

coating the granular absorbent material with a coating agent to produce a coated absorbent material, wherein the coating agent is a biocide that forms a surface-bonded film on the granular absorbent material;

adding a super-absorbent polymer to the 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 granular absorbent material is not perlite, and

wherein the cleaning composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition, and further

wherein the granular absorbent material comprises vermiculite.

2. The method of claim 1, wherein the granular absorbent material is coated with the coating agent by vapor deposition, pressure micro droplet spray or fuming or fogging nozzle.

3. The method of claim 2, wherein the coating agent is coated in an amount that constitutes 0.1 to 10% (w/w) of the cleaning composition.

4. The method of claim 1, wherein the sanitation agent is added in an amount that constitutes 0.1 to 10% (w/w) of the cleaning composition.

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

grinding an absorbent material to produce a granular absorbent material used in a coating step;

coating the granular absorbent material with a coating agent to produce a coated absorbent material, wherein the coating agent is a biocide that forms a surface-bonded film on the granular absorbent material;

adding a super-absorbent polymer to the 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 granular absorbent material is not perlite, and

wherein the cleaning composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition, and further

wherein the granular absorbent material comprises vermiculite, and also

wherein the granular absorbent material has a surface area per mass ratio up to 10,000 m²/g.

6. The method of claim 5, wherein the granular absorbent material is coated with the coating agent by vapor deposition, pressure micro droplet spray or fuming or fogging nozzle.

7. The method of claim 6, wherein the coating agent is coated in an amount that constitutes 0.1 to 10% (w/w) of the cleaning composition.
