ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a catalyst called Willard Water. More particularly, it refers to a bactericidal concentrate formed from a mixture of the catalyst and ultra pure water and the use of the bactericidal concentrate to treat bums and dermal lesions.
BACKGROUND OF THE INVENTION
Willard Water is set forth in U.S. Pat. No. 3,893,943 as a novel catalyst and its preparation is therein described. Willard Water has a poor shelf life insofar as its use in a bactericidal solution. A concentrate is needed that will provide an extended shelf life and will be useful to treat epidermal body surfaces that may be contaminated with bacteria.
SUMMARY OF THE INVENTION
The present invention solves the above problem by providing a bactericidal concentrate with a liquid mixture ratio of about 1.2 to 3 ml of Willard Water to about one liter of ultra pure water having an electrical resistance of 16-26 megohms, total dissolved solids of less than 0.04 parts per million and a specific conductance of less than 0.10 microhm. The Willard Water employed in the concentrate is as described in U.S. Pat. No. 3,893,943. The concentrate is used to apply to the epidermis of patients to control bacterial contaminations. A gel for treatment of bums also can be formed from a gel formulation containing about 5.6 ml of Willard Water. The concentrate of this invention has a shelf life in a plastic container of at least two and one half years compared to a shelf life of Willard Water combined with distilled water of less than seven months.
DETAILED DESCRIPTION OF THE INVENTION
The liquid bactericidal concentrate of this invention is made from 1.2 to 3 parts by volume of Willard Water made according to the description of the catalyst described in U.S. Pat. No. 3,893,943, incorporated herein by reference, to 1000 parts by volume of ultra pure water.
The ultra pure water is made by first passing potable water through a 5 micron sediment filter and then through a granulated activated charcoal bed having a depth of about 20 cm. The water is then passed through a 1.2 cubic foot mixed bed deionizer resin such as SIBRON Model No. NM-60. The resulting treated water is passed twice through a standard reverse osmosis process utilizing Model FC-018A filters obtained from Water Link Technologies, Inc. and then through a 0.2 micron filter to obtain ultra pure water having an electrical resistance of 16-26 megohms, total dissolved solids of less than 0.04 parts per million and a specific conductance of less than 0.10 micromho.
The ultra pure water is mixed in a holding drum with the Willard Water at varying ratios of 1000 to 1.2-3 parts by volume depending upon the bacteria for which control is sought.
About 1.2 ml of Willard Water is added to one liter of the ultra pure water to create a liquid mixture for treatment of Staphylococcus. Streptococcus, E. coli and Pseudomonas bacteria. In treating bums with a liquid, 2.8 ml of Willard Water is added to one liter of the ultra pure water. The solutions are buffered to a pH of 8.0 to 8.5.
For further treatment of burn victims, a gel is formed containing 5.8 ml of Willard Water in 1000 ml of a gel formulation. The gel formulation will contain sodium, silicate, sulfate of ester of oil of Euphorbiaceae, magnesium, calcium, chloride, glycerin, xanthin gum, methanol, paraben, potassium sorbate and sodium benzoate. The gel formulation should be buffered to a pH of 8.0 to 8.5.
Either the liquid concentrate or gel concentrate is applied directly to a patient's skin surface containing a burn or other lesion. The burn or lesion begins healing within a few days without being affected by bacterial contamination.
