Benefits of technology

This patent is about a disinfectant that uses calcium hydroxide and sodium hypochlorite to kill microorganisms like bacteria and fungus. The disinfectant is made by mixing calcium hydroxide in water and then adding sodium hypochlorite. The resulting solution can be used to disinfect objects by applying it to them. The technical effect of this patent is to provide a simple, effective way to disinfect objects using a combination of calcium hydroxide and sodium hypochlorite.

Problems solved by technology

Often the most efficacious disinfectants also have harmful side effects to the individuals who use them.
For example, solutions containing sodium hypochlorite are commonly used as disinfectants however these products can release harmful chlorine vapours which can have negative health consequences such as impaired respiratory health.
However, the addition of the substantial amounts of sodium hydroxide required for stabilization, results in solutions that are highly caustic and therefore also harmful for those handling such solutions.

Embodiment Construction

[0013]It has been found that Ca(OH)2 acts to stabilize hypochlorite in solution. By stabilizing the hypochlorite, the release of toxic chlorine gas may be reduced. Further it has been found that less Ca(OH)2 is required to stabilize hypochlorite in solution as compared to the amount of NaOH that would be required to achieve a similar result. Since less Ca(OH)2 can be used, the resulting formulation can be less caustic and therefore less harmful to the user.

[0014]It has also been found that the use of Ca(OH)2 results in less precipitation than using NaOH to stabilize hypochlorite. This is particularly advantageous in the application of the disinfectant formulation as a spray disinfectant where the precipitates can cause spray nozzles to become clogged and malfunction.

[0015]Ion channels in a cell serve many functions apart from electrical signal transduction: chemical signalling, (Ca2+ as a second messenger), transepithelial transport, regulation of cytoplasmic or vesicular ion concen...

Abstract

The application relates to disinfectant formulations comprising calcium hydroxide and sodium hypochlorite and further relates to a method of manufacturing the disinfectant formulations and methods of disinfecting an object using the disinfectant formulations.

Description

CROSS REFERENCE TO PRIOR APPLICATIONS[0001]The present application claims priority under the Paris Convention to U.S. application Ser. No. 61 / 698,076, filed Sep. 7, 2012, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to disinfectant formulations and in particular to formulations comprising calcium hydroxide and sodium hypochlorite for disinfecting surfaces.BACKGROUND OF THE INVENTION[0003]The health effects caused by bacteria, fungus, mold, viruses and other micro-organisms that can grow on surfaces is a serious concern, especially in the food service and preparation industry and in the medical field.[0004]Disinfectants are substances that are applied to non-living objects to destroy microorganisms that are living on the objects. Generally, disinfectants work by destroying the cell wall of microbes or interfering with the metabolism. Various disinfectants have been used with mixed results. Often the most e...
