ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a disinfectant composition which can be safely and effectively utilized as a disinfectant, bactericide, fungicide, cold sterilizer, virucide and the like, and which in addition to being highly effective for the eradication of germs, viruses, fungus and bacteria in a variety of uses, is odorless, colorless, non-toxic, non-corrosive, non-flammable, and non-staining.
2. Description of the Related Art
Many different types of disinfectants, bactericides, fungicides, cold sterilizers and the like have been in use in a variety of industries, including the pharmaceutical and medical industries, for some time. Typically, these chemicals have been utilized as replacements to heat sterilization, radiation sterilization, or other less desirable techniques, in order to effectuate a more cost effective, convenient and/or presumably safer manner of eliminating potentially harmful germs, viruses, funguses and bacteria. Additionally, however, a prominent consideration has always been the strength or power of the chemical disinfectant as compared with other methods. Indeed, it is the general desirability for a more effective or powerful product which has, in some industries, resulted in effectiveness and cost outweighing safety. For this reason, very stringent guidelines are placed on all chemical disinfectant compositions and a user must take great care on the nature of the use to which a chemical disinfectant is being put.
As can be appreciated, a variety of different chemical composition and solutions have been provided in various industries, each solution claiming to have different and/or better qualities than other chemicals also available for the same purposes. Moreover, while each chemical does have certain beneficial attributes, typically, particular chemicals are tailored for particular industries based upon the nature and/or tolerances of the articles to be disinfected. For example, chemicals utilized for disinfecting floors and walls tend to be stronger and harsher than chemicals utilized for disinfecting surgical equipment, human or animal patients or even food products. As such, the present art lacks an effective chemical composition which is substantially effective for a multitude of cross over uses and in any of a variety of different industries wherein such disinfection or sterilization is needed, with little or no modification.
Despite the specialization of particular chemicals, a primary drawback associated with substantially all effective disinfectant or sterilization chemical formulations, and indeed a primary reason for lack of multi-purpose use ability, is the corrosive and/or toxic nature of the chemical compositions. For example, even though such concerns are not as significant when dealing with an industrial setting wherein machinery or floors must be cleaned or sterilized, the health of the workers that are charged with the disinfecting and sterilizing duty, as well as of the workers who must be present in a vicinity of the area that has just been cleaned, nevertheless make the toxic and corrosive nature of industrial cleaners a concern. Of course, in other industries wherein the articles to be cleaned are more sensitive or come into closer contact with a human, such as for the sterilization of surgical equipment and food products, any toxic or corrosive qualities exhibited by the chemical will render that chemical not useable for the particular tasks. Accordingly, even the presently available chemicals which are being marketed and utilized are either generally ineffective or are overly corrosive for complete safety. It is for those very reasons that other methods of cleaning and/or sterilization are constantly being sought. As such, there is a substantial need in the art for a non-toxic and non-corrosive chemical disinfectant/sterilizer which is highly effective and eliminates substantially all harmful germs, funguses, viruses and bacteria present in a treated article. Moreover, it would be highly beneficial to provide such a chemical composition which can be used topically on living human or animal patients without any harmful results to the patient, and can be utilized even on the most sensitive of articles, such as medical equipment including plastics, metals, glass, rubber, optics structures and the like.
It is also noted, that of the various disinfectant and sterilization chemicals presently available, a number of them implement a quaternary ammonium salt as a primary active ingredient in the chemical formulation. Such existing formulations, however, while seeking to benefit from the potential of the quaternary ammonium salt for eliminating germs, viruses, funguses and bacteria, have not been capable of providing a truly effective and safe chemical formulation that utilizes the beneficial aspects of the quaternary ammonium salt, but which also avoids the highly toxic and corrosive aspects thereof. Indeed, those in the art have sought to implement a wide variety of different formulations and chemical additives, however, the finished chemical products have proven to either be generally ineffective or remain substantially corrosive and toxic. For example, previously known or utilized diluents have generally rendered the product ineffective or have not eliminated its corrosivity or toxicity. Therefore such known quaternary ammonium salt based disinfectants and sterilizers have generally been limited to isolated industrial type uses.
As a result, it would be highly beneficial to provide an improved disinfectant and cold sterilizer which can utilize the bacteria, virus, fungus and germ killing effects of a quaternary ammonium salt, but which recognizes the specific benefits of utilizing a particular quaternary ammonium salt in a particular chemical formulation in order to achieve substantially unexpected and remarkably safe bacteria, virus, fungus and germ killing results in a safe, yet effective manner. Moreover, such a product, in addition to being safe, non-toxic, and non-corrosive should not compromise effectiveness in favor of that safety, non-corrosivity and non-toxicity. The disinfecting composition of the present invention achieves such a solution.
SUMMARY OF THE INVENTION
The present invention is directed towards a disinfectant composition to be utilized to disinfect or sterilize a variety of articles including surfaces, medical instruments and equipment, living human and animal patients, foods, plants, and contaminated fluid bodies.
Specifically, the present invention includes a disinfectant composition containing between 0.05% and 9% by volume of Dimethyl Benzyl Lauryl Ammonium Bromide as part of an initial base mixture. Moreover, the disinfectant composition further includes water which is substantially pure, substantially bacteria free and substantially ion free. Furthermore, the water has preferably been treated so as to be sufficiently pure, ion-free and bacteria free such that a relatively large volume of water is utilized to act as a diluent of the Dimethyl Benzyl Lauryl Ammonium Bromide and create a stable, safe and effective base mixture, without minerals or other impurities usually present in water adversely reacting with the Dimethyl Benzyl Lauryl Ammonium Bromide and reducing the effectiveness thereof and/or causing harmful characteristics to be exhibited thereby.
The pH of the pure water available for use in connection with the invention varies from one place to another. Therefore, depending on the pH of the water, there are two formulas, which provide alternate embodiments of the invention.
A first preferred disinfectant composition of the present invention is used when the pH of the water used in the composition is between about 7.0 and 8.8. Dimethyl benzyl lauryl ammonium bromide is added in the amount of 0.05 to 9.4 g. per 100 ml. of solution, and preferably 0.17 g. per 100 ml. of solution, increasing the pH to about 8.8 to 9.2. A strengthening additive, ammonium sulfate, is added, preferably in a solution of approximately 50 g. per 100 ml. of water (prefe
