ABSTRACT:
TECHNICAL FIELD
The present invention is concerned with a cleaning/-disinfecting composition incorporating spore forming microbiological bacteria.
BACKGROUND OF THE INVENTION
Biological based products not only offer facilities a method of quickly re-establishing a system's biomass after shocks, but they are also becoming more prevalent as a means to prevent such situations and improve overall performance through continual maintenance dosages. Continual treatment with a biological based product provides enhanced abilities to handle difficult to degrade compounds, reduce solids loading, improve removal of FOG's (fats, oils & greases) and extend the time period between physical pump-outs in certain systems such as septic tanks.
Current technology does not offer a product or method by which water hardness deposits can be efficiently removed from surfaces while concurrently providing viable bacterial cultures to the facility's waste collection and/or treatment system.
The object of the invention is to provide a product suitable for removal of hard water deposit and general cleaning that through use will actually augment the activity of on-site wastewater treatment operations instead of interfering as can occur in many cases. The product is a combination of an acid based cleaner/disinfectant that incorporates a stabilized culture of bacterial spores.
The utilization of the microbial materials is to destroy offensive odors and their source that may be present on a surface. In addition, the microbial materials provide preventative maintenance for the wastewater collection system and improved activity in downstream treatment plants. The purpose of the antimicrobial component is to kill various types of microorganisms found on the surface which might pose health concerns or contribute to nuisance odors. A particularly important aspect of formulating antimicrobial products is that they remain stable for a long period of time. The microbiological materials likewise need to be stable in the presence of the other components of a cleaning composition such as the quaternary ammonium compounds.
It is an object of the present invention to obtain an effective disinfectant and hard surface cleaning composition that is aqueous based.
It is an object of the present invention to obtain and utilize in combination a disinfectant, hard surface cleaning, and bacterial composition that is stable for a long period of time, but also allows the microbial material to remain active after the intended use of the product.
It is an object of the present invention to utilize an aqueous composition containing bacteria from the genus Bacillus in the presence of disinfectants such as quaternary ammonium compounds.
It is an object of the present invention to perform general cleaning tasks in a more efficient manner, whereby the multi-step cleaning process to clean, disinfectant and control odors on hard surfaces is decreased. The utilization of this invention will permit the saving of labor time and reduce chemical inventory.
It is an object of the present invention to utilize compositions in particular aerosol compositions that contain a bacterial content that provides better environmental fate attributes to both on site waste treatment systems and municipal treatment plants through biological augmentation of the indigenous bio-mass.

SUMMARY OF THE INVENTION
Described is an aqueous cleaning and disinfecting composition comprising:
an effective mineral dissolving amount of an organic acid of at least 1% by weight of the cleaning compositions;
an effective amount of a spore forming microbial composition;
an effective cleaning amount of a blend of wetting agents, the first wetting agent having a hydrophobic/lipophobic number (HLB) of about 10 and higher and a second wetting agent having an HLB number of about 5 or less;
an effective amount of a thickening agent and water.
Also described is a method of cleaning a soiled hard surface comprising applying the above composition to the surface and drying the surface thereby cleaning the surface.
The composition as described above is particularly useful for the overall desires of the present application for cleaning and disinfecting hard surfaces.
Also described is a powder composition containing the active ingredients of the organic acid, spore forming microbial composition, blend of wetting agents plus additional filler.
Also described is an aerosol composition containing the active ingredients of the organic acid, spore forming microbial composition, blend of wetting agents, thickening agents and a propellant.
