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.
Claims19
A bioenzymatic, concentrated cleaning product, comprising:
- 15 to 55% by weight bacillus spores, capable of generating extracellular enzymes 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 about 5.0 to about 9.5;
- and water;
- wherein the 15-55% by weight bacillus spores have an average diameter of 5-50microns and remain suspended in the water under static conditions and the bioenzymatic, concentrated cleaning product is substantially free of organic solvents.
A bioenzymatic, concentrated cleaning product, comprising:
- 15-55% by weight bacillus spores having an average particle diameter of about 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;
- and
- a balance consisting essentially of water;
- wherein the 15-55% by weight bacillus spores are able to remain suspended in the water for two years under static conditions and the bioenzymatic, concentrated cleaning product is substantially free of organic solvents.
A method of preparing a bioenzymatic cleaning product from a concentrate, comprising the steps of:
- mixing 15-55% by weight bacillus spores 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, and a balance consisting essentially of water, to form a concentrate;
- the 15-55% by weight bacillus spores in the concentrate having an average diameter of 5-50 microns and remaining suspended in the water under static conditions;
- and
- diluting the concentrate with water using a proportioner system, to yield the bioenzymatic cleaning product;
- wherein the bioenzymatic cleaning product is substantially free of organic solvents.
