Definitions

• the present invention relates to an antimicrobial composition, particularly bactericidal, virucidal, fungicidal and mycobacterial for the cleaning of contaminated surfaces and to the use of the same.
• the surfaces of objects and articles ranging from floors, ceilings, door panels, glass windows to, e.g., medical devices, systems, machinery, kitchen worktops, kitchen equipment, can all be contaminated or colonized by microorganisms such as viruses, bacteria, mold, fungi, and in fact, if left dirty, are almost always contaminated with microbes to some degree.
• Known antimicrobial compositions such as, e.g., commercially available disinfectants, soaps, detergents and sanitizing agents used to fight against contamination of solutions and surfaces with pathogens such as viruses or bacteria are only partly effective in reducing or preventing contamination of any nature, whether viral, microbial, fungal or mycobacterial.
• DBPs Disinfection Byproducts
• QACs quaternary ammonium compounds
• QACs are highly toxic to numerous aquatic organisms, comprising fish, daphnids, algae, rotifers, and other utilized microorganisms, as well as to the environment and humans.
• Improved or new antimicrobial compositions and disinfectants, soaps, detergents and sanitizing agents are more efficient, more effective and/or safer when considering the duration of prevention against contamination and/or when considering the degree of decontamination and/or when considering the risk to human health or to the environment.
• a first object of the invention is to provide an antimicrobial composition, particularly bactericidal, virucidal, fungicidal and mycobacterial for the cleaning of contaminated surfaces and its use, with an improved antimicrobial activity against microbes such as viruses, bacteria, fungi and mycobacteria, without posing an unacceptable risk to the environment or human health.
• a second object of the invention is to provide an antimicrobial composition, particularly bactericidal, virucidal, fungicidal and mycobacterial for the cleaning of contaminated surfaces, which has improved as far as killing microbes, preferably viruses, bacteria, fungi and mycobacteria is concerned, and/or the prevention of the microbial growth on a surface, which, in contrast to known state-of-the-art antimicrobial compositions, does not contain compounds which may cause adverse consequences for the environment and human health, and which is sufficiently effective at eliminating contamination.
• Another object of the present invention is to devise an antimicrobial composition, particularly bactericidal, virucidal, fungicidal and mycobacterial for the cleaning of contaminated surfaces and its use which allows the mentioned drawbacks of the prior art to be overcome within a simple, rational, easy and effective to use as well as affordable solution.
• Figures 1-3 are representative graphs of bactericidal efficacy tests and of the duration of the bactericidal action over time.
• the present invention relates to an antimicrobial composition, particularly bactericidal, virucidal, fungicidal and mycobacterial for the cleaning of contaminated surfaces.
• antimicrobial activity has its normal scientific meaning throughout the text, and here relates to the activity that kills or blocks the growth of microorganisms.
• carrier as used herein has its normal scientific meaning throughout the text and here relates to anything in which or on which contaminants, such as microorganisms, i.e. microbes such as bacteria, may be present and/or grow.
• such a carrier is an aqueous solution, a gas such as air, an object, or a surface such as the surface of an object, such as, e.g., the surface of a ceiling, wall, floor, table, kitchen worktop, machinery, etc.
• surface has its normal scientific meaning throughout the text, and here relates to any part of an object that constitutes its outer layer, comprising the flat surfaces such as e.g. floors, ceilings, door panels, glass panes, etc., but also other objects such as, e.g., medical devices, systems, machinery, kitchen equipment, etc.
• contamination as used herein relates to the undesirable presence of pathogens inside or on an object, in an aqueous solution or in a gas such as air.
• infectious agent has its normal scientific meaning throughout the text, and herein relates to a biocidal antimicrobial agent or an antimicrobial or biocidal solution which is, e.g., applied to the surface of inanimate objects or to a gas such as air, or, in order to destroy living microorganisms on such objects or to prevent contamination of such objects by microbes such as bacteria, viruses, fungi and mycobacteria.
