1. A method of formulating a cleaning composition, comprising the steps of:
- (a) grinding an absorbent material to produce a granular absorbent material, 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;
(b) coating the granular absorbent material with a biocide to produce a coated absorbent material, wherein the biocide is applied to granular absorbent material by vapor deposition, by a pressure micro droplet spray, or by a fuming or fogging nozzle to form a surface bonded film on the granular absorbent material, and 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;
(c) mixing the coated absorbent material with a sanitation agent so that the coated absorbent material absorbs the sanitation agent to form the cleaning composition, wherein the sanitation agent is selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solution, peracetic acid, quaternary amine solutions, alcohol solutions and combinations thereof; and
(d) adding to the cleaning composition 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 combinations thereof,wherein the cleaning composition comprises 25-30% (w/w) of the granular absorbent material, 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.

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.
