DEODORANT AND METHOD 0]? MAKING SAME.
Application filed November 27, 1923. serial No. 677,223.
An object of my invention is to provide a deodorant which will be effective in Stepping or destro ing odors of perspiration,
which will be hygienic, which may be apl plied with facility and convenience, which will be non-greasy and harmless to the clothing, and which will be easy and inexpensive to produce.
Many deodorants now on the market are in the form, of salves, powders or liquids containing astringents which operate to close the pores and thus check the perspiration, some being. scented or perfumed so that their own conspicuous odors render the 16 odors of perspiration inappreciable. It is a fact well known that there is acertain danger attendant upon artificially closing the pores, and it is also recognized that the perfumed and scented odors frequently be- 20 come objectionable, particularly when mingled with that of'perspiration. There is an obvious disagreeable feature about ap plying salves, and because of the greasy nature of the salves and many of the liquids they will rub off on the clothing unless some protection is provided, which is not always possible to do. Powders are also disadvantageous for the. reason that they do not have the quality of adhering and hence they are both wasteful and inconvenient of application.
By my invention I am able to make a deodorant in solid cake or stick form which can be applied to any portion of' the body by merely rubbing it over the parts, such as under the armpits or between the toes. The nature of my product is such that it does not crumble but rubs off easily in a smooth even film, and yet is not greasy to any objectionable degree. Furthermore, while it is itself practically odorless, it has the property of destroying the characteristic odor of the perspiration. It does not have any astringent action upon the pores, it does not soil the fingers, does not rub off on the clothing, is invisible when applied and retains its solidity at any atmospheric temperature.
The deodorant constituents of my product are zinc oxide and boric acid, preferably in substantially equal amounts by weight.
While the deodorant properties of these substances individually have been heretofore known, I believe that I am the first to have is non-greasy in its nature and yet can be" applied in a thin crumbling.
I have found that the best body or binder for the deodorant powders is spermaceti which is made slightly soft or pliable by a proper amount of a petroleum jelly. .While' other waxy substances might perhaps be employed as the binder to produce the solid form of the product,'I have not been able to obtain entirely satisfactory results with other than spermaceti and petrolatum combined in about two parts by weight of the former to one part of the latter. The product is improved by adding a few drops of petroleum oil to the mixture.
My invention also contemplates a method of combining the powders with this binder so as to afi'ord the maximum quantity of the powders and at the same time make a product in which thepowders'are evenly distributed and which will rub off smoothly without crumbling. I have found that when the product is properly made it can readily be molded to the desired shape of sticks or cakes, and a convenient sha e'of the product, which my invention inc udes, is a fiat oval stick having a round end. A stick of this shape has the advantage that when applied to the concavities of the body, as, for
film or layer without example, in the armpits, it conforms tothe shape of that part of the body and may be applied thereto with one or two sweeps of the stick over the part.
In the drawings, I have shown one form in which the product may be molded in accordance with my invention, Figure 1 being .an elevation of the stick; F1 ure 2 being a top end view; and Figure 3 sing a bottom end view thereof.
In accordance with my inventioirI first parts by weight of the spermaceti to one of the .vaseline gives the best results, and the product will be further improved by adding a'few drops of pptroleum oil, such as whitemineral oil. T e spermaceti should be melted slowly and the molten mixture should be raised to a temperature of from 140 to 150 F. I then take a owder containing an equal mixture by weight of zinc oxide and boric acid. and stir into the molten liquid a quantity thereof substantially equal in weight to that of the molten liquid. This powder should be poured in slowly and the llquid should be constantly stirred as the powder is entering it. If the temperature of the molten liquid is properly regulated a homogeneous and stable mixture will thus be obtained. If the tempierature is too low the liquid will not be, su cient-ly thin to permit of a thorough mixture of the wder therein, while if the temperature is substantially above 150 F. the result is a curdling action.
While the spermaceti will melt at about 110 F., the temperature of the molten liquid is lowered by the addition of the cold powder, and it is therefore necessary to have the initial temperture suiiiciently high to leave the mass in a molten-condition after the powder is stirred in. l have found" that a quantity of the powder equal by weight to substantiallly 50% of the entire mass will reduce the temperature from around 145 to around 115 15. This is, therefore, substantially the maximum amount of powder that can be used for the reason that the liqpid cannot safely be at a temperature su stantially above 150 F. when the powder is stirred in. I
After the powder is stirred into the molten liquid, the mass is poured into suitable molds, where it quickly hardens. In fact,
the material hardens so quickly that it is desirable to provide a heat insulating jacket around the body while pouring the liquid into the molds. l have found that aluminum molds are entirely satisfactory. Bakelite molds are also satisfactory, although more expensive. 7
I prefer to make the .molds of a shape toproduce the stick illustrated in the draw ings. The stick A of the solid deodorant material produced as above described, is of a flat, oval shape with a rounded end, the major axis of the oval being conveniently about one and one-quarter inches in length. While this at ordinary temperatures is entirely nongreasy and will not soil the fingers, it does yield to the temperature of the body OK when pressed hard against the part. For this reason, in order to protect the'fingers of the user, I prefer to cover' the lower end of the stick with a suitable protective wrapping B. This makes a handy and compact form for the material.
While my invention is not'limited to any reeaoie exact or very careful proportions, an excellent product is produced from the following formula by weight of the constituents: 25% zinc oxide, 25% boric acid, 33% spermaceti, 10%70 vaseline, of 1% white petroleum Without the petroleum products, it is evident that the stick or cake will tend to crumble when rubbed over the skin, particularly when the stick is relatively cold. The vaseline and white petroleum oil in the proportions stated make the product just soft enough to rub ofl smoothly at any temperature without making the product greasy to the touch. I
In order to make the product less visible when applied to the skin than would be if left in its natural white color, a small quantity of a pinkish coloring material, such as an oil soluble aniline dye, may be added thereto to cause the product to simulate a flesh color.
lln addition to its property of stopping the odors of perspiration without clogging the pores, and of reducing excessive perspirations to normal, my improved deodorant is refreshing, soothing and healing, being a good antiseptic for minor cuts and sores.
It is evident that, if desired, the proportion between the zinc oxide and boric acid may be changed, and that other changes may be made and equivalents may be substituted for the constituents mentioned without departing from the spirit of my invention as expressed in the following claims.
