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.

First claim

What is claimed is:

1. A liquid loading composition, comprising:
a granular absorbent material coated with a biocide; and
a sanitation agent absorbed in said granular absorbent material,
wherein the biocide constitutes 0.1% to 10% of the liquid loading composition.

2. The liquid loading 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 liquid loading composition of claim 1 , wherein the granular absorbent material comprises ceramic minerals.

4. The liquid loading composition of claim 2 , wherein the ceramic minerals comprise perlite and/or vermiculite.

5. The liquid loading composition of claim 1 , wherein the biocide comprises an agent selected from the group consisting of silanes, siloxanes, aminopropyltrimethoxysilane, quaternary amines, fumed metal hydroxides, solutions of silver, solutions of copper and combinations thereof.

6. The liquid loading composition of claim 5 , wherein the biocide forms a surface bonded film on the granular absorbent material.

7. The liquid loading 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.

8. The liquid loading composition 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.

9. The liquid loading composition of claim 1 , further comprising: a thickening agent, a gum, an absorbent polymer or combinations thereof.

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