Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel aluminum-hydrogen-oxygen composite and a method for producing this composite. In particular, this complex contains aluminum, oxygen and hydrogen in specific proportions and forms, so that the complex can be used in compositions and organic substances such as acne lotions, bleaching creams, deodorants, hair removal compositions. and inhibiting the decomposition of biological material treatments.

Commercially available non-prescription products that can be applied to the skin, such as cosmetics, cosmetic aids, preservatives, medicines, deodorants, etc., act on the pores of the skin either on a dilatory or astringent basis. None of the treatments for acne are satisfactory.

Expansion effect? Is the compound used skin with impurities? Although it can be cleaned, as a result, the pores of this skin remain dilated for quite some time and are therefore particularly susceptible to air contaminants such as sulfur dioxide and tar. The result of prolonged use of products containing this dilatory effect is that, after a short period of "success", an aggravated skin condition usually occurs.

Compositions that utilize astringent action are usually applied after cleaning the skin with hydrogen peroxide or other strong oxidizing agents. Oxygen from hydrogen peroxide acts effectively and directly, while the subsequent action of astringents is a “deep” cleansing of the skin? inhibit.

Additionally, compositions used on the skin may help eliminate unpleasant odors, unpleasant odors, and skin irritation, depending on the intended use of this composition. Oxygen-deficient impurities on the skin, such as 77 (eg pimples) or acne? Must be dried. Since these compositions are to be used on the skin, they must also be bacteriostatic, non-toxic, non-irritating and completely safe.

Research continues into new and improved compounds useful in compositions applied to the skin, such as hair removal compositions, acne lotions, roll-on deodorants, and bleaching creams. The present invention was made as a result of this research.

It is therefore an overall object of the present invention to obviate or substantially alleviate the above-discussed problems of the prior art.

P)'ll of the suspension rises from about 5.8.

The invention also provides suspensions produced by this method.

The aluminum-hydrogen-oxygen complex of the present invention is a bright, amorphous, peroxide material containing aluminum, oxygen, hydrogen, and at least trace amounts of unbound halogen. A significant limitation is that the aluminum metal from which this aluminum-hydrogen-oxygen complex is formed is hexagonal in structure and contains trace amounts of silicon. This aluminum-hydrogen-
Oxygen complexes do not burn and are not explosive.

This aluminum-hydrogen-oxygen complex, further described below, appears to be a blue-green amorphous material of A4z(HzOz)1aH6 and forms on non-immersed metal surfaces during the process of the present invention. This aluminum-hydrogen-oxygen complex is initially referred to as BB-1.

Aluminum from which BB-1 is manufactured? The term "activated aluminum" as used to describe aluminum that has been treated with a source of mercury and subsequently exposed to partial immersion in hydrolodenic acid (at a temperature not greater than about 40°G from approximately ambient temperature) aluminum metal. This “activation”
, the aluminum metal on a non-immersed surface remains in its elemental form, but is ``aluminum metal'' in that it entraps or confines ``free'' chlorine (or other halogens) internally in trace amounts.
It is ``lattice-like.'' Moreover, this lattice-entrapped free chlorine allows the aluminum-hydrogen-oxygen composite of the present invention to release oxygen and hydrogen.

The trace silicon structure required to be included in the aluminum metal used in this invention is of two types.

The usual shape is spherical or cylindrical, but a small portion of the silicon is in the second shape, which is noretto and hexagonal. Throughout this discussion, in most cases silicon is determined as a whole rather than in terms of silicon structure.

However, hexagonal silicon appears to be important in order to obtain the desired properties of the aluminum-hydrogen-oxygen composites of the present invention. What is the ratio of the two forms of silicon? It was extremely difficult to determine. In commercially available aluminum containing traces of silicon, the hexagonal silicon appears to be about one inch less than the total silicon.

The Q aluminum-hydrogen-oxygen composite of the present invention can be produced by t) a double process method. The method will be described with reference to the drawings.

Using the apparatus of FIG. 1, an aluminum bar or rod 1 is placed in a container 2, preferably made of glass or other acid-resistant material. A thin layer of hydrohalic acid, preferably hydrochloric acid, is placed in the container so that the aluminum is slightly covered. The shape of the aluminum is not important, but
Bars or rosso are generally preferred.

The purpose of this acid treatment is to remove oxides from the aluminum surface and to prevent further development of oxides on the surface. The aluminum should be pure, generally at least about 99.94% pure, typically at least about 9.
9.98% and preferably at least about 99.99%
It should be of high purity. The purity of aluminum can be easily determined experimentally since the presence of oxides is indicated by a sudden increase in the temperature of the acid bath.

However, this aluminum metal u i oo=i
Must not be pure. some silicon, generally about 60
>= about 100, typically about 45 to about 95, and preferably about 60 to about 90 parts per million (ppm
) is necessary for all the silicon to be reconstituted in the aluminum. Using less than about 30 ppm total silicon will lead to a hydrogen- and oxygen-free composite that is sufficient for the desired purpose. However, lower total silicon content aluminum is also useful in the present invention when aluminum metals containing a greater proportion of hexagonal silicon than currently commercially available are utilized. Using more than about 100 ppm total silicon creates process difficulties as the silicon tends to raise the temperature of the solution and displace the desired hydrogen and oxygen gases.

Other impurities, such as iron, may be present in the aluminum to the extent discussed above. The amount of iron present in the aluminum should generally be less than about 50, typically less than about 40, and preferably less than about 30% by weight of silicon. It is desirable to keep the total iron content to a minimum since iron tends to react with the oxygen in the system and thus be depleted.

After immersion in the acid solution, the aluminum is then contacted with or coated with a source of mercury, preferably by placing the aluminum in a bath or similar type of apparatus.

This process? This is carried out in the presence of an oxygen-containing atmosphere, for example air.

This mercury acts as a catalyst to effect changes in the aluminum structure.

There is no critical value for the temperature at which these first two steps are carried out, but it must not be conducive to oxide and/or chlorine gas formation. generally about 10 to about 45, typically about 15
to about 35°C, and preferably from about 20 to about 30°C. Can be used.

This acid and mercury contact as desired? This can be done simultaneously as shown in FIG. 2, where the rod 1 is immersed in an acid bath 3 and a heavier mercury bath 4.

Although the length of time of contact with mercury is relatively short, regardless of whether the device of FIG. 1 or 2 or other suitable device is used, longer contact is harmful. Generally a time r of at least about 15, typically about 15 to about 60, and preferably about 15 to about 60 seconds can be used.

This mercury acts as a catalyst for changes in the aluminum structure.

The mercury-contacted aluminum thus formed is then partially immersed in a hydrogen halide solution. The acid suitable for sowing for this purpose is hydrochloric acid. This step places A on the non-immersed surface of mercury-contacted aluminum, □(H20□)18
This results in the growth or formation of an aluminum-hydrogen-oxygen complex of blue-green amorphous material believed to be H6.

This aluminum-hydrogen-oxygen complex occurs as a growth or formation of BB-1, which can be recovered as a powdered material and used directly. Optionally, this substance is (a) this complex? (b) cooling the suspension; and (c) bringing the P)I of the suspension to about 5.0°.
5.8 (BB-1 suspension).

This BB-i complex can be formed in a variety of ways, and the method itself is not critical. For example, after contact with mercury, aluminum-hydrogen or rods so treated have a concentration that can be determined experimentally, but is generally about 1 to about 2 normal? A bath of hydrochloric acid? Can be partially immersed in another container containing A blue-green amorphous material is then formed as a non-immersed metal surface. This growth is illustrated in Figure 3, where the composite 5 is shown as being formed over an acid bath on a non-immersed surface, which upon drying results in a powder of BB-i composite.

The temperature at which this complex is formed should generally be from 5 to about 40°C, typically from about 20 to about 30°C, and preferably from about 22 to about 25°C. If the aluminum starting material is not sufficiently pure, a sharp and negative increase in the temperature of the reaction environment occurs at this point. Is this temperature 40℃? should not be exceeded, since the desired hydrogen and oxygen gases of the BB-1 complex are released at these higher temperatures. Temperatures below 5° C. are undesirable because the reaction rates are not usually commercially viable at these temperatures.

In both embodiments, oxide-free aluminum is treated with mercury to change the structure of the aluminum and activate it? Aluminum done and then treated like this? Formation of aluminum-hydrogen-oxygen complexes on exposed metal surfaces brought into (or kept in contact with) hydrochloric acid by partial immersion? A complex is formed by causing this.

This contacting step is preferably carried out for about 75 to about 100 minutes. A blue-green BB-1 complex is the product of this step.

The BB-i composite is then dried at ambient temperature or, preferably, in a suitable drying oven. Foods that release chlorine gas in the heat that is used must not be expensive. The temperature should generally be from about 5 to about 50°C, typically below about 40°C, and preferably from about 20 to about 40°C. Relative humidity should preferably be about 60%.

The length of time required for drying depends on the layer thickness of the composite and the dimensions of the drying oven and can be determined experimentally. Drying typically takes about 30 to about 150 minutes, typically 50 to about 125 minutes, and preferably about 75 to 100 minutes. A blue-green powder, BB-1, is the product of this drying process.

To form a BB-1 suspension, the BB-1 powder was passed through a simple 11 Soxhlet apparatus 12 as shown in FIG.
will be introduced in The flask 13 of the Soxhlet apparatus 12 is filled with a solution of hydrohalidic acid, preferably hydrochloric acid, preferably about 3 normal. Then flask by normal means? Heat to boiling point. Is hydrogen chloride vapor a Soxhlet device 12? After penetrating and condensing in the water-cooled condenser 15, the powder is partially redissolved in the simple 11 and in the flask 13? Recirculate. This process is repeated until the simple 11 of the Soxhlet device 12 is empty.

Is this part of the remelting process? The amount of time required to perform can be determined experimentally, but generally about 30 to about 200, typically about 50 to about 150, and preferably about 70
It can be used for about 120 minutes. This BB-1 powder is then recycled into a strong acidic liquid such as hydrochloric acid. This is recycled and recovered, partly in the form of a solution and partly in the form of a finely clouded suspension, referred to as the BB-1 suspension.

After cooling the suspension to a temperature generally below about 50° C., typically from about 15 to about 40° C., and preferably from about 20 to about 30° C., the p)) of the complex is generally about 5.02° C.
11) about 5.8, typically about 5.2 to about 5.6,
and preferably from about 5.6 to about 5.5.

The pHt can be increased by treatment with strong hydroxides such as sodium hydroxide or potassium hydroxide. There is no critical value for the concentration of hydroxide, but it is generally about 1 to about 4N, typically about 1.5 to about 6.5N, and preferably about 3 to about 4N.

This increase of -1 can be monitored with a regular meter.

BB-11M resulting from this method! M solution can be used in various formulations in the fields of cosmetics, beauty aids, medicine, deodorants, etc., at various macroportions that can be easily determined experimentally.

Even in small amounts, this BB-IM@ liquid has the unique ability (in the presence of halogen salts) to release oxygen and hydrogen when used in oxygen and hydrogen-containing compositions such as cosmetics, medicines, beauty aids, deodorants, etc. have These compositions are often used on the skin. Rodenides are generally present on the skin as a result of normal physiological processes and thus
It should be understood that activating the -1 suspension.

This BB-i suspension can be used in the following weight percentages of the total composition depending on the end use: acne cream or lotion (about 6 inches), hair removal composition (about 4.5 inches), etc. width), face cream (approximately 5 inches), armpit deodorant (approximately 6 inches).

The invention is further illustrated in the following examples. All parts and percentages in the Examples, as well as the specification and claims, are by weight unless otherwise specified.

Example 1 Is this example manufacturing BB-1? Illustrate. Approximately 60 to 100
Five hundred grams of aluminum metal rond having no more than 0.02% impurities, including ppm silicon, is placed in a 66 inch long shallow glass container as shown in FIG.

Is this aluminum? Contact with 3N hydrochloric acid at 20° C. in sufficient amount to cover the aluminum rond. Thereafter, the aluminum rond is removed from the acid bath and immersed in a mercury bath for about 10 minutes under humid (about 60 degrees relative humidity) air-atmosphere conditions.

The mercury-contacted Aluminum 522N hydrochloric acid bath is then partially re-immersed. Growth is seen on the entire unimmersed portion of the aluminum surface and the aluminum rod begins to dissolve in the hydrochloric acid bath on the immersed surface.

The blue-green amorphous material that begins to form on the non-immersed surface is BB.
-1 is an aluminum-hydrogen-oxygen complex.

This material is recovered and used directly in deodorants, bleaching agents, biomaterial treatments, or indirectly in making composites.

Example 1 2 This example is BB-11-1!8! Here we show another way to build. The same process as in Example 1 is used, but the starting material is aluminum metal rond with less than 0.02% impurities and about 0.3 to about 1 ppm hexagonal silicon therein.

．． By weight of the total composition, this composition can be applied directly to skin containing acne disorders.

The BB-1 of the present invention behaves in a virtually sandbag manner with that of the prior art compositions. While this is an astringent with only η≧, the composite of the present invention has pores? Do not close or expand. This complex is rich in readily released oxygen, and this is activated by halogen salts such as hydrogen chloride (present in sweat from the surface of the skin), so this complex has a constant and stable presence of oxygen. The flow? discharge.

Pimples are directly attacked by this released oxygen. Since face shocks are isolated foreign bodies and do not have an oxygen supply like residual skin, they are thought to be "oxygen starved." Oxygen from the complexes penetrates easily and effectively into the surfaces and these? Dry, while remaining skin remains unaffected.

-1' By using an oxygen carrier compound as described above as an anti-inflammatory formulation, the affected skin is kept under control during the appearance of acne.

This complex can be used in other compositions for use on the skin. One of these compositions is a Fi version deodorant. There are problems with the prior art in applying the correct amount to the underarm area. Too little is not effective.

Too much will cause irritation. However, the complexes of the invention are non-irritating to the skin. Additionally, salts during sweating trigger the release of hydrogen and oxygen. When sweating stops, the action of the aluminum-hydrogen-oxygen complex also stops. When sweating begins again, the action of the complex begins again.

Generally, about 1 per 1 β of sewage
It was found that a range of about 20.9 should be satisfied from l
A range of from about 2 to about 12.9 is preferred.

The scientific phenomenon on which the invention is based is not fully understood;
And while I do not wish to be bound by any particular theory, it appears that the subgrain structure of aluminum undergoes profound changes when it is under chemical and electrochemical attack.

It appears that the spheroidal shape of the silicon trace material in the aluminum changes to a hexagonal shape as a result of the "free chlorine" of the complex and due to the interaction of the hydrochloric acid solution and the mercury-treated aluminum. Is there a hexagonal pore in the aluminum-hydrogen-oxygen composite of the present invention similar to the external shape of a hexagonal silicon crystal? It can be observed. The properties of BB-1 also appear to be related to the phenomenon that the composites of the present invention can release oxygen and hydrogen in the presence of catalysts.

Furthermore, when ordinary aluminum is introduced into a 1N or 2N hydrochloric acid solution, for example, aluminum chloride (and water)
manufacturing takes place. However, when the mercury-treated aluminum used in the method of the invention is partially immersed in hydrochloric acid, the behavior is quite different. Furthermore, the formation of aluminum chloride and other aluminum compounds? However, after about 8 to about 72 hours, a complex forms on the unsoaked surface, starting as a blue-green amorphous material.

The principles, preferred embodiments, and mode of operation of the invention are set forth in the foregoing description. The invention herein intended to be protected, however, should not be construed as limited to the particular forms disclosed, which should be viewed as illustrative rather than limiting. It is from. Variations and modifications may be made by those skilled in the art without departing from the spirit of the invention.
