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.

First claim

What is claimed is:

1. A liquid cleaning composition comprising:
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. A liquid cleaning composition comprising:
a granular absorbent material coated with a biocide;
at least two sanitation agents comprising dimethyl benzyl ammonium chloride and dimethyl ethyl benzyl ammonium chloride; and
sodium polyacrylate,
wherein the granular absorbent material comprises perlite, 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.

3. The composition of claim 2 , wherein the biocide is a silane.

4. The composition of claim 2 , wherein the granular absorbent material constitutes 30-60% (w/w) of the liquid cleaning composition.

5. The composition of claim 2 , wherein the silane is present in the composition at a concentration between 0.1 to 1% (w/w).

6. The composition of claim 2 , wherein each of the at least two sanitation agents is absorbed in the granular absorbent material.

7. The composition of claim 2 , wherein each of the dimethyl benzyl ammonium chloride and the dimethyl ethyl benzyl ammonium chloride is present in the composition at a concentration between to 1 to 10% (w/w).

8. The composition of claim 2 , wherein the sodium polyacrylate is present in the composition at a concentration between 1 to 5% (w/w).
