## Title
Method for treating diaper rash using superhydrated bacteriostatic topical preparation with stable acid pH

## Abstract

A method for treating diaper rash, leg ulcers and bed sores using super hydrated bacteriostatic topical preparation with a stable acid pH 5.82, by applying this topical application, which is a mixture of anhydrous lanolin (USP), water, boric acid powder (USP), edible corn starch, white petrolatum, cosmetic grade, and zinc oxide ointment (USP 20% zinc oxide) mixed in a paddle mixer at a temperature of about 100° F. to 107° F. then applying topically, the super hydrated bacteriostatic preparation, at room temperature, on the rash, leg ulcers, or bed sores.

## Background
BACKGROUND OF THE INVENTION
A skin rash is a very common, particularly in diapered individuals, including neonates, babies and adults. There has been much study and effort to date to eliminate this problem and present studies indicate that in many cases the rash is due to a yeast/bacterial growth in a neutral or alkaline environment and by lowering the pH along with a mild antiseptic, in an aqueous environment, stops the yeast/bacterial growth.
The term “rash” may include:

    
    
        RASH—An eruption on the body with no elevation on the skin.
        ULCER—necrosis of epithelial tissue.
        BED SORE—Decubitus ulcer; ulceration of tissue covering prominent bony parts of the skin.
        EXANTHEM—Skin rash; ulcer
        DIAPER RASH—Condition caused by excessive urinary ammonia.
    
    


OBJECTS OF THIS INVENTION
An object of this invention is to create a topical preparation, in an aqueous environment among components that are aqua-phobic, which is accomplished by super-hydrating lanolin (wool fat) to create an environment that approximates ten percent water
SUMMARY OF THE INVENTION
This invention for a method to cure a rash, particularly a diaper rash, leg ulcers, and bed sores, is aimed at having an acid environment at a pH of about 5.82, having a range of from pH 5 to pH 6, and including boric acid as a bacteriostat to create and maintain an acid environment, or mantle of pH 5.82, in an aqueous environment to increase the rate of epithelial cell regeneration, as epithelial cells regenerate more rapidly in a wet environment than in a dry environment.

DETAILED DESCRIPTION OF THE INVENTION
This present application is for a salve for treatment of diaper rash, leg ulcers and bed sores, and includes an aqueous mantle of water dispersed in anhydrous lanolin, with addition of boric acid plus addition of zinc oxide ointment USP; (20% zinc oxide) plus edible corn starch, plus white cosmetic grade petrolatum.
The water or aqueous/acid mantle is of major importance and is attained by addition of 200 cc water to 300 grams of anhydrous lanolin, and mixing in a paddle mixer at a temperature range of 38° C.-42° C. equal to 100° F.-107° F., then add 50 grams of boric acid (USP) to the water—lanolin mix followed by 454 grams of edible corn starch, 454 grams of white petrolatum (cosmetic grade) and 454 grams of zinc oxide ointment USP (20% zinc oxide), mix all ingredients together in paddle mixer.
The pH of the final mix is about 5.82, and with the aqueous/acid mantle is suited for curing a rash, and protecting skin from developing a diaper rash.
The method of preparation of this salve is critical, and is not merely mixing the ingredients but includes special steps' of adding warm water at about 100° F. to 107° F. to anhydrous lanolin (USP) and mixing in a paddle mixer to obtain water saturation of the anhydrous lanolin then boric acid powder (USP) grade is added to the anhydrous lanolin—water mix and dispersed therein by the mixing apparatus, then edible corn starch is added, mixed into the anhydrous lanolin-water boric acid (USP) mix, and further mixed in the mixing apparatus and white petrolatum (cosmetic grade) is added to the anhydrous lanolin plus water plus boric acid (USP) plus edible starch plus white petrolatum (cosmetic grade) is added and mixing continued plus zinc oxide ointment (USP 20% zinc oxide) is added and mixing continued to attain a thorough mixture. All the mixing of the ingredients to be at, or about 100°-107° F. for good dispersion of the components of this topical preparation

Function of Ingredients
Zinc oxide (USP) 20% zinc oxide, is an astringent and a protectent.
Boric acid is bacteriostatic and creates an acid environment with a pH of 5.82. which helps to establish an acid mantle, and in the case of urinary incontinence it neutralizes the generated ammonia.
Corn starch is an absorbent and a lubricant.
Super hydrated lanolin (wool fat) creates an aqueous environment (at about 10% water) with the other ingredients that are aquaphobic.
