Abstract

A method for formulating a 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 liquid loading composition. Liquid-loading compositions that can absorb liquids in many applications, including clean-up and farming, are also disclosed.

Claims (12)

1. A method of making a liquid loading composition, comprising the steps of:

coating a granular absorbent material with a biocide to form a coated granular absorbent material, wherein the biocide is a silane that constitutes 0.1% to 10% of the liquid loading composition, and wherein the granular absorbent material comprises perlite; and

mixing the coated granular absorbent material with at least two sanitation agents, wherein the sanitation agents are absorbed in the coated granular absorbent material, and wherein the at least two sanitation agents comprise dimethyl benzyl ammonium chloride and dimethyl ethyl benzyl ammonium chloride.

2. The method of claim 1 , wherein the perlite is coated with the silane by vapor deposition, pressure micro droplet spray or fuming or fogging nozzle.

3. The method of claim 1 , wherein perlite comprises 30-60% (w/w) of the cleaning composition.

4. The method of claim 1 , wherein the biocide forms a surface bonded film on the high surface area solid.

5. The method of claim 1 , wherein the liquid loading composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition.

6. The method of claim 1 , further comprising the step of:

adding a modifying agent to the liquid loading composition in an amount sufficient to achieve desired physical characteristics for the liquid loading composition.

7. The method of claim 6 , wherein the modifying agent comprises sodium polyacrylate.

8. The method of claim 1 , wherein the at least two sanitation agents constitute between 1 to 10% (w/w) of the liquid loading composition.

9. The method of 7 , wherein the sodium polyacrylate constitutes between 0.3 to 5% (w/w) of the liquid loading composition.
