Abstract

A concentrated bioenzymatic cleaning product is provided which maintains a homogenous composition under static conditions and does not require shaking or mixing prior to dilution. The concentrated bioenzymatic cleaning product includes bacillus spores, a suspending and/or rheology modifying agent, an odor control agent, a pH adjuster, and water. The types and amounts of ingredients are selected to maintain the bacillus spores in suspension under static conditions, enabling the concentrated bioenzymatic cleaning product to be diluted using a proportioner system.

First claim

We claim:

1. A bioenzymatic, concentrated cleaning product, consisting essentially of:
bacillus spores, having an average diameter of 5-50 microns and selected from the group consisting of extracellular protease enzymes, extracellular urease enzymes, extracellular amylase enzymes, extracellular lypase enzymes, extracellular cellulase enzymes, and combinations thereof;
a suspending and/or rheology modifying agent;
an odor control agent;
sufficient pH adjuster to maintain a pH of 7.0 to about 9.5;
optional wetting agents and dispersing agents; and
a balance of water;
wherein the bacillus spores are present at 15% to 55% by weight and are able to remain suspended in the water for two years under static conditions.

2. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the suspending and/or rheology modifying agent is selected from the group consisting of xanthan gum, guar gum, acrylate copolymers, celluloses, smectic clays, and combinations thereof.

3. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the suspending agent comprises xanthan gum.

4. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the suspending and/or rheology modifying agent is present at about 0.1-2% by weight.

5. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the odor control agent is selected from the group consisting of fragrances, malodor control agents, and combinations thereof.

6. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the odor control agent is present at about 0.1-2% by weight.

7. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the pH adjuster is selected from the group consisting of organic acids, mineral acids, and combinations thereof.

8. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the pH adjuster comprises lactic acid.

9. The bioenzymatic, concentrated cleaning product of claim 1 , wherein the water is present in an amount of at least about 45% by weight.

10. A bioenzymatic, concentrated cleaning product, consisting essentially of:
35% to 55% by weight bacillus spores having an average particle diameter of 5-50 microns;
about 0.1-2% by weight of a suspending and/or rheology modifying agent;
about 0.1-2% by weight of an odor control agent;
an acidic pH adjuster
optional wetting agents and dispersing agents; and
a balance of water;
wherein the bacillus spores are able to remain suspended in the water for two years under static conditions.

11. The bioenzymatic, concentrated cleaning product of claim 10 , wherein the suspending agent comprises a gum.

12. The bioenzymatic, concentrated cleaning product of claim 10 , wherein the odor control agent produces a citrus odor.

13. The bioenzymatic, concentrated cleaning product of claim 10 , wherein the pH adjuster comprises sufficient acid to maintain a pH of about 5.0-9.5.

14. The bioenzymatic, concentrated cleaning product of claim 10 , wherein the pH adjuster comprises sufficient acid to maintain a pH of about 6.0-8.0.

15. The bioenzymatic, concentrated cleaning product of claim 10 , wherein the water is present in an amount of at least about 45% by weight.

16. A method of preparing a bioenzymatic cleaning product from a concentrate, consisting of the steps of:
mixing 15% to 55% by weight bacillus spores having an average particle diameter of 5-50 microns with a suspending and/or rheology modifying agent, an odor control agent, sufficient pH adjuster to maintain a pH of about 5.0-9.5, optional wetting agents and dispersing agents, and a balance of water, to form a concentrate; and
diluting the concentrate with water using a proportioner system, to yield the bioenzymatic cleaning product.

17. A bioenzymatic concentrated cleaning product from a concentrate, consisting essentially of:
bacillus spores having an average particle diameter of 5-50 microns and selected from the group consisting of extracellular protease enzymes, extracellular urease enzymes, extracellular amylase enzymes, extracellular lipase enzymes, extracellular cellulose enzymes, and combinations thereof;
a suspending and/or rheology modifying agent;
an odor control agent:
sufficient pH adjuster to maintain a pH of about 5.0 to about 9.5;
optional wetting agents and dispersing agents; and
a balance of water;
wherein the bacillus spores are present at 35% to 55% b weight and are able to remain suspended in the water for two years under static conditions.

18. A bioenzymatic concentrated cleaning product, consisting of:
bacillus spores having an average particle diameter of 5-50 microns and selected from the group consisting of extracellular protease enzymes, extracellular urease enzymes, extracellular amylase enzymes, extracellular lipase enzymes, extracellular cellulose enzymes, and combinations thereof;
a suspending and/or rheology modifying agent;
an odor control agent:
sufficient pH adjuster to maintain a pH of about 5.0 to about 9.5;
optional wetting agents and dispersing agents; and
a balance of water.
