Patent Description:
Microbes may often be present on many common objects and surfaces in everyday life. Microbes can include, for example, bacteria, fungi, spores, viruses, prions, microorganisms such as, e.g., Mycobacterium tuberculosis, listeria monocytogenas, escherichia coli, pseudomonas aeruginosa, salmonella typhimurium, salmonella enteritidis, Yersinia pestis, staphylococcus aureus, bacillus subtilis, enterobacter aerogenes, streptococcus faecalis, legionella pneumophila, vibrio parahaemolyticus, bacillus cereus, and other gram positive and gram negative bacteria. Several such microbes/ microorganisms, individually or in combination, can cause illness or other health problems, for example, when they come into contact with humans and/or animals, or when they are ingested along with food which has contacted them. These microbes present health hazards due to infection or contamination. When microorganisms are present on the surface of a substrate they can replicate rapidly to form colonies. The microbial colonies form a coating on the substrate surface which is known as a biofilm. Biofilms frequently consist of a number of different species of microorganisms which in turn can be snore difficult to eradicate and thus more hazardous to health than individual microorganisms. Some microorganisms also produce polysaccharide coatings, which makes them more difficult to destroy.

For example, hospitals and other medical facilities may have a particular need for sterile and/or uncontaminated surfaces, both in surgical and general medical areas as well as in convalescence facilities, where patient exposure may be significant and resistance to such microbes may be lowered.

Much time and effort can be spent, for example, on disinfecting and sterilizing medical instruments, testing devices. Often, such devices can be provided with disposable components or covers (e.g., disposable thermometer probes) to avoid cross-contamination between patients. Disposable needles are also commonly used. Such disposable materials involve increased costs and increased waste, as well as potential safety issues associated with their disposal.

The food-preparation and delivery industry is another area in which presence of microbes (e.g., Bacteria) can be problematic. Food preparation facilities, if contaminated with microbes, can lead to contamination of food which may cause health problems when ingested. For example, restaurants, food manufacturing plants, and even home kitchens can contain preparation surfaces, utensils, and equipment which may contaminate food that comes into contact with them. There may be, for example, a particular need for reducing a presence and spreading of microbes in meat packaging plants.

Public and private facilities such as, e.g., restrooms, may also contain surfaces which can harbor and spread microbes, leading to potential health problems. To address this issue, products such as antimicrobial soaps and air dryers for hands may be offered, as well as disposable paper towels. Nevertheless, microbes may still be harbored on such objects as faucet and toilet handles, door knobs, keys, dispenser levers.

In the transportation industry, including land, sea, air, and space vehicles, there may also be particular surfaces which can harbor and spread microbes, leading to potential health problems. For example, rental cars may benefit from disinfecting frequently touched surfaces. In particular, isolated environments such as, e.g., airplanes and submarines can also be safer if surfaces are disinfected.

Other common objects may benefit from antimicrobial treatments, which can inhibit or prevent spread of microorganisms between people and/or animals that come into contact with such objects. For example, musical instruments, such as harmonicas, flutes, clarinets, computer peripherals, communications equipment such as, e.g., telephones, pet accessories such as leashes and carriers, and/or other common household objects could benefit from antimicrobial surfaces.

However, the phenol-free broad spectrum disinfectant cleaner composition is not effective in inactivating viruses such as Norovirus, Adenovirus and Polyomavirus. Further the described phenol-free broad spectrum disinfectant cleaner composition having no tuberculocidal efficacy.

<CIT> refers to the use of N, N-Bis-(<NUM>-aminopropyl)-laurylamine as effective components in a liquid aldehyde-free composition active against tuberculosis.

<CIT> refers to a powdered aldehyde and phenol free cleansing instrument disinfectants containing N, N-bis (<NUM>-aminopropyl) lauryl amine, a quaternary ammonium compound, a powdered complexing and a powdery, chemically neutral carrier substance.

<CIT> refers to disinfectants effective against mycobacterium tuberculosis containing germicidal quaternary ammonium salt and an alkoxylated amine compound.

<CIT> refers to a broad spectrum disinfectant includes a quaternary ammonium halogen, an alkaline agent, a chelating agent, a nonionic surfactant coupler, at least one alkoxylated nonionic surfactant, and water or any aliphatic alcohol. The disinfectant composition is phenol-free, is effective in eradicating microorganisms such as various fungi, and is stable to gamma-irradiation.

<CIT> refers to a formulation effective against microorganisms including herpes simplex types <NUM> and <NUM> viruses, comprising an alkyl (<NUM>% C14, <NUM>% C16, <NUM>% C12) dimethyl benzyl ammonium chloride.

<CIT> refers to an alkaline disinfectant and cleaning agent comprising one or more selected quaternary ammonium salts, one or more selected alcohol alkoxylates and one or more alkylamines. By selection of the ingredients, an agent is provided which can be formulated as a concentrate and which, as a diluted aqueous working solution, has a cleaning performance in combination with a microbicidal activity. Quaternary ammonium chloride-containing products (also known as "quats") have been used in hard surface disinfection for many years. As a broad-spectrum disinfectant, they have acceptable efficacy against some organisms (e.g. Staphylococcus aureus), but often fall short in efficacy against mycobacteria and viruses. Thus, other harsher disinfectant or sporicidal products, such as Sodium chlorite (NaClO<NUM>), ozone, H<NUM>O<NUM> and peracetic acids are often used when mycobactericidal and virucidal efficacy is required.

Compositions and procedures have been developed to reduce or prevent a presence of microbes on certain surfaces. More importantly, such compositions may often not provide a rapid and high level of microbial efficacy, in particular a sufficient virucidal efficacy which could reduce the risk of microbial contaminants. Further, peroxide or chlorite containing antimicrobial compositions may have a material destructive effect on surfaces.

One can see that there is a continuing need for improved antimicrobial cleaners that are material non-destructive and having a rapid and high level of tuberculocidal and mycobactericidal efficacy and a rapid and high level of efficacy against Norovirus, Adenovirus and Polyomavirus.
