Description

* N.0. 34524 * J \

Activated complex of aluminum, hydrogen and oxygen and process for its preparation and application.

The invention relates to new complexes of aluminum, hydrogen and oxygen and to processes for the preparation thereof. In particular, the complexes contain aluminum, oxygen and hydrogen in certain proportions and form such that these complexes are useful in organic preservative compositions such as acne lotions, bleaching creams, deodorants, depilatory preparations and for treatment of biological materials.

Over the counter commercially available agents that can be applied to the skin such as cosmetics, antiseptics, drugs, deodorants, etc., act on the basis of either a widening or an astringent effect on the skin pores. Neither is satisfactory for treating acne.

Although dilating compounds can rid the skin of any impurities present, the result is that the skin pores remain dilated for a considerable time and are therefore particularly susceptible to the entry of air pollutants such as sulfur dioxide and tar. In the long term, the consequence of the use of such dilating agents is therefore usually that after a brief "success" a deteriorated condition of the skin occurs.

Astringent compounds are usually used after cleaning the skin with hydrogen peroxide or other oxidizing agents. Although the oxygen from the hydrogen peroxide is effective and effective, the subsequent action of the astringent makes "deep" cleaning of the skin impossible.

Furthermore, formulations applied to the skin should help dissipate unpleasant odors, reduce skin irritations, and dehydrate low oxygen impurities on the skin, such as blackheads or acne, depending on the intended application of the formulations.

Since these compositions are intended for use on the skin, they must also be bacteriostatic, non-toxic, non-irritating and completely safe.

The search for new and better compounds useful in compositions applied to the skin such as depilatory preparations, acne lotions, roll-on deodorants and bleaching creams has led to the invention.

Therefore, a general object of the invention is to provide a $ 701149 2% 7% solution to the aforementioned problems of the prior art.

More particularly, the invention involves a complex of aluminum, hydrogen and oxygen useful in compositions that can be applied to the skin.

Another object of the invention is to provide a process for the preparation of such an aluminum-hydrogen-oxygen complex.

A further object of the invention is to provide a method for applying this complex in the form of a solid or semi-solid composition to the skin.

A further object of the invention is to provide a method for using this complex in combination with one or more liquids.

Another object of the invention is to prevent the degradation of biological material.

Further objects and advantages of the invention are apparent from the description of the invention and of the preferred embodiment.

An aspect of the invention is a method of preparing an activated powder. This method mainly consists of: a. Contacting metallic aluminum with a purity of at least 99.94% by weight, containing at least trace amounts of silicon, with an acid of such a type and a concentration that oxide is deposited on the metal removed and its formation prevented; b. contacting the acid-treated metallic aluminum with a mercury source in an oxygen-containing atmosphere; and c. partially dipping the mercury-contacted aluminum in a solution of a hydrogen halide for such a time that a crystal-like substance, which is the activated powder, forms on the mercury-contacted aluminum.

The invention also relates to the product obtained according to this method.

The invention further relates to a method for preparing a suspension of the complex of aluminum, hydrogen and oxygen which can deliver oxygen and hydrogen in the presence of a halogen-containing compound. This method mainly consists of: a. Contacting metallic aluminum with a purity of at least 99.94% by weight, which contains at least trace amounts of silicon 8701149 * 3, with an acid of such a type and a concentration to remove oxide on the metal and prevent its formation; b. contacting the acid-treated metallic aluminum with a mercury source in an oxygen-containing atmosphere; c. partially dipping the mercury-contacted aluminum in a solution of a hydrogen halide for such a time that a complex forms on the mercury-contacted aluminum; 10 d. at least partially redissolving the complex in a solution of a hydrogen halide to form a suspension; e. cooling the suspension; and f. increasing the pH of the suspension to about 5.0-5.8.

The invention also relates to the suspension thus obtained.

Fig. 1 is a schematic vertical sectional view of an embodiment of the device and components used in the first two steps of the method of the invention.

FIG. 2 corresponds to FIG. 1, but is a different embodiment of the first two steps of the method.

Fig. 3 corresponds to FIG. 1 illustrating the formation of a complex of aluminum, hydrogen, and oxygen on an unimmersed metal surface in a hydrochloric acid bath during the third step of the process of the invention.

Fig. 4 is a schematic representation of a Soxhlet apparatus in which partial redissolving of a complex of aluminum, hydrogen and oxygen formed on a non-immersed metal surface is performed.

The complex of aluminum, hydrogen and oxygen of the invention is a light, amorphous, super-oxygenated material containing aluminum, oxygen and hydrogen and at least trace amounts of unbound halogen. An essential limitation is that the aluminum metal from which the complex is formed contains trace amounts of silicon in a hexagonal structure. The aluminum, hydrogen and oxygen complex is non-flammable and non-explosive.

This complex of aluminum, hydrogen and oxygen, which is further described below, has an putative composition of Α1χ2 ^ Η202 ^ 18Η6 »1S 0611 blue-green amorphous material and 40 is formed on an unimmersed metal surface during the 8701149, 4 method of the invention. This complex of aluminum, hydrogen and oxygen is provisionally designated BB-1.

The term "activated aluminum" used to describe the aluminum from which BB-1 is made is understood to mean metallic aluminum which has been treated with a mercury source and subsequently subjected to partial immersion in a hydrogen halide at temperatures at preferably between 5 ° C and 40 ° C. In the "activated" state, the aluminum metal remains on the non-immersed surface in the element form but is "clathratic" in the sense that it keeps "free" chlorine (or other halogen) contained in trace amounts. Furthermore, the clathratically enclosed free chlorine enables the complex of aluminum, hydrogen and oxygen to release oxygen and hydrogen.

The structure of the silicon trace to be present in the aluminum metal 15 according to the invention has two forms. The usual shape is a spherical or a cylinder shape, but a small portion of the silicon is in a second shape that is hexagonal in circumference. In the description, the silicon is generally measured in total regardless of the structure. Nevertheless, it is believed that the presence of hexagonal silicon is essential to achieve the desired properties of the aluminum, hydrogen and oxygen complex of the invention. Establishing a relationship between the two forms of silicon is extremely difficult. In commercially available aluminum containing traces of silicon, hexagonal silicon appears to make up less than 1% of the total amount of silicon.

The aluminum, hydrogen and oxygen complex of the invention can be prepared in a multi-step process. The method is described in conjunction with the drawings.

With the device of Fig. 1, an aluminum rod (1) is placed in a tray (2), which is preferably of glass or other acid-resistant material. A thin layer of a hydrogen halide, preferably hydrochloric acid (3), is introduced into the tray, such that the aluminum is just covered. The shape of the aluminum is not essential although a rod is generally preferred.

The purpose of the acid treatment is to remove oxides from the aluminum surface and to prevent further oxide formation on the surface. The aluminum should be pure, generally at least 99.94%, usually at least 99.98%, and preferably at least 99.99%. The purity of the aluminum can easily be determined by trial and error since the presence of oxides β 7 Λ 4 4 ί Q Ö * V i 1 $ φ 5 is demonstrated by a rapid rise in the temperature of the acid solution.

However, the aluminum metal should not be 100% pure. It is necessary that some silicon, generally about 30 to about 100, usually 45 to 95, and preferably 60 to 90 parts per million (ppm) of total silicon be present in the aluminum. The presence of less than about 30 ppm of silicon results in a complex that does not contain enough hydrogen and oxygen for its intended purpose. However, if aluminum metal were available with a higher hexagonal silicon content than is currently the case, aluminum with a lower total silicon content according to the invention would also be useful. Using more than 100 ppm total silicon presents process engineering problems because silicon tends to heat the solution and expel the desired hydrogen and oxygen.

Other impurities such as iron may be present in the aluminum within the above limits. The amount of iron present in the aluminum should generally be less than about 50, usually less than 40, and preferably less than 30%, by weight of the silicon. It is desirable to keep the iron content as low as possible so that iron tends to react with and thus withdraw the oxygen in the system.

After immersion in the acid solution, the aluminum is contacted with a mercury source, preferably by placing the aluminum in a bath or similar device. This treatment takes place in the presence of an oxygen-containing atmosphere such as air. The mercury acts as a catalyst that causes a change in the aluminum structure.

The temperature at which the first two steps are performed is not essential but should not contribute to the formation of oxides and / or chlorine gas. In general, a temperature range of 10-45, usually 15-35, and preferably 20-30 ° C is useful.

If desired, the treatment with acid and with mercury can take place simultaneously as shown in Fig. 2, in which aluminum rod (1) is immersed in an acid bath (3) and a heavier mercury bath (4).

Regardless of which device is used, that of Fig. 1, Fig. 2 or another, the duration of contact with mercury can be relatively short, generally at least 15, usually 15-60, and preferably 15-30 seconds, although a longer contact time is not directly harmful.

40 The aluminum thus formed with mercury contacted becomes 87 0 1 1 4 9

6, then partially brought into a solution of a hydrogen halide. Preferably, this hydrogen halide is hydrochloric acid. Here, on the non-immersed surface of the aluminum contacted with mercury, a complex of aluminum, hydrogen and oxygen of blue-green amorphous material is formed, the gross formula of which is assumed to be Al 12 ^ 202 ^ 18 ^ 6

The aluminum, hydrogen and oxygen complex arises as a fouling or formation - BB-1 - which is collected as a powdery substance and can be used directly. Optionally, this material can be further processed by (a) at least partially redissolving the complex in a solution of a hydrogen halide to form a suspension; (b) cooling the suspension and (c) increasing the pH of the suspension to about 5.0-5.8 (BB-1 suspension).

The BB-1 complex can be formed in various ways and the method is not essential in itself. For example, upon contact with mercury, the aluminum rod thus treated may be partially immersed in another container with a hydrochloric acid bath generally from about 1 to about 2 normal. A blue-green amorphous material then forms on the non-immersed metal surface. This formation 20 is shown in Figure 3, where the complex (5) forms over the acid bath on the non-immersed surface and becomes a powder of the BB-1 complex upon drying.

The temperature at which this complex is formed is generally between 5 and 40, in particular between 20 and 30, and preferably between 22 and 25 ° C. At this point, a sudden deleterious rise in the temperature of the reaction medium can occur if the starting aluminum was not pure enough. The temperature should not exceed 40 ° C because at higher temperatures the desired hydrogen and oxygen of the BB-1 complex escape. Temperatures below 5 ° C are not desirable because the reaction rate is then usually no longer commercially interesting.

In each embodiment, the complex is formed by treating the oxide-free aluminum with mercury changing the structure of the aluminum and activating the aluminum followed by contacting (or keeping in contact) the thus-treated aluminum with hydrochloric acid by partial immersion to form a complex of aluminum, hydrogen and oxygen on the exposed metal surface. This contacting step preferably takes about 75 to 100 minutes. The product of this step is a blue-green BB-1 complex. The BB-1 complex is then dried either at room temperature or, preferably, in a suitable drying oven. The heating used must not be such that chlorine gas is released. The temperature should generally be between 5 and 50, usually below 40 and preferably from 20 to 40 ° C. The relative humidity is preferably about 30¾.

The time required for drying can be determined experimentally because it depends on the layer of the complex and also on the dimensions of the drying oven. Usually drying takes about 30 to 150, especially about 50 to 125, and preferably about 75 to 100 minutes. The product of this drying step is a blue-green powder, BB-1.

To form the BB-1 suspension, the BB-1 powder is introduced into the container (11) of a Soxhlet device (12) as shown in Fig. 4. Flask (13) is filled with a hydrogen halide solution, preferably hydrochloric acid (14), preferably about 3 normal. Flask (13) is heated to the boiling point of the solution in the usual manner. The hydrogen halide vapors pass through the Soxhlet apparatus (12) and, after condensation on the water-fed cooler (15), partially dissolve the powder in container (11) and the solution flows back to flask (13). This process can be continued until container (11) of device (12) is empty.

The time required for this partial redissolving step can be determined experimentally, and generally lasts about 30 to 200, especially 50 to 150, preferably 70 to 120 minutes. The BB-1 powder is recycled in a strongly acidic liquid, such as hydrochloric acid. It is recycled partly in the form of a solution and partly in the form of a fine suspension and both forms are collectively referred to as BB-1 suspension.

After the slurry has cooled to a temperature of generally less than 30, usually between 15 and 40, and preferably between 20 and 30 ° C, the pH of the complex is raised, generally to about 5.0-5 , 8, especially up to 5.2-5.6 and preferably up to 5.3-5.5.

The pH can be raised using a strong solution of a hydroxide such as sodium hydroxide or potassium hydroxide. The concentration of the solution is not essential and is generally between 1 and 4, usually between 1.5 and 3.5, and preferably between 2 and 3 normal.

The rise in pH can be monitored with a pH meter.

The BB-1 suspension thus obtained can be used in various preparations in the field of cosmetics, pharmaceuticals, deodorants and the like in varying percentages which can easily be determined experimentally.

This BB-1 suspension has the unique ability to deliver oxygen and hydrogen, even in small amounts (in the presence of halogen salts) when used in an oxygen and hydrogen containing composition such as cosmetics, pharmaceuticals, deodorants, etc. Such compositions are often used on the skin applied. Halogens are usually present on the skin, generally as a result of ordinary physiological processes, thus activating the BB-1 suspension.

The BB-1 suspension can be used in the following percentages by weight of the total composition depending on the application: acne cream or lotion (approximately Z%)> depilatory preparation (approximately 15 4.5-5¾), face cream (approximately 5 %), armpit deodorant (about 3¾).

The invention is further illustrated by the following examples. All parts and percentages are parts by weight and percentages by weight unless otherwise indicated.

Example I

20 Preparation of BB-1.

A 500g aluminum rod with no more than 0.02¾ impurities, including 30-100ppm silicon, is placed in a 91cm shallow glass container according to Fig. 1. An amount of 3N hydrochloric acid of 20 ° C is introduced into the tray to cover the aluminum bar. The rod is then taken out of the bath and placed in a mercury bath under moist air for about 10 minutes (relative humidity about 30¾).

The aluminum bar contacted with mercury is then partially immersed in a 2N hydrochloric acid bath. Growth is observed on all non-immersed portions of the aluminum surface, and on the immersed surface, the aluminum rod begins to dissolve in the hydrochloric acid bath.

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

This material is collected and used either directly in deodorants, bleaches, depilatories, biological material treatment agents, or further used for complex preparation.

Example II Preparation of BB-1.

The procedure of Example I is followed with the proviso that the aluminum rod contains no more than 0.02 en impurities and between 0.3 and 1 ppm hexagonal silicon impurity.

Example III

Preparation of a BB-1 suspension.

100 g of the BB-1 complex obtained according to Example I are placed in a container (11) of a Soxhlet device (12). Flask (13) 10 is filled with 1 liter of 3N hydrochloric acid (14) and heated to the boiling point of the hydrochloric acid. While the hydrochloric acid is continuously boiled, the container is siphoned four times in about 90 minutes. Then container (11) is empty and flask (13) contains a fine suspension or a solution. After cooling the suspension to about 20 ° C, a solution of 3N potassium hydroxide is slowly added until the pH becomes 5.4. The pH rise is monitored with a Beekman pH meter. The product thus obtained, a BB-1 suspension, can be used in certain cosmetics, deodorants, medicines and other preparations.

The BB-1 of the present invention is believed to act in a manner which differs significantly from the mode of action of the prior art compositions. Although somewhat sara-drawing, the present complex neither closes nor widens the pores. Because the complex is rich in easily released oxygen and it is activated by halogen salts such as sodium chloride (which is present in the sweat on the skin's surface), this complex gives off a constant and lasting flow of oxygen.

30 Blackheads are immediately dealt with by this released oxygen. Since blackheads form isolated foreign material that does not have an oxygen supply like the rest of the skin, they are believed to be "oxygen-depleting". The oxygen from the complex easily and effectively penetrates and dries out the blackheads while not affecting the rest of the skin. By using an oxygen-carrying compound as described above as an acne-fighting composition, the affected skin is controlled during acne development.

The complex can also be used in other compositions used on the skin. One such composition is an ointment deodorant. With the prior art deodorants, problems arise in applying the correct amount to the armpit area. Too little has no effect, too much can irritate. However, the present complex is not irritating to the skin. In addition, the salt from sweat returns the release of hydrogen and oxygen. When perspiration ceases, the action of the aluminum, hydrogen and oxygen complex also ceases. When perspiration starts again, the functioning of the complex starts again.

A prepared lotion is thus obtained which is ready for application to the skin.

In another application, wastewater can be deodorized and its alkalinity decreased in conjunction with an oxygen enrichment to facilitate degradation of the contaminants.

This can be done by adding BB-1 to the wastewater. Due to the varying composition of wastewater and the desired degree of deodorization and the desired reaction rate, specific ratios of BB-1 to wastewater should be established taking into account the material to be treated, the temperature and others for those skilled in the art. obvious factors. Generally, an amount of from 1 to about 20 g of BB-1 per liter of waste water will be sufficient, with a preference for from about 2 to about 12 g per liter of water.

The phenomena upon which this invention is based are not fully understood, but it is believed, without any particular theory, that the sub-grain structure of aluminum undergoes profound changes upon chemical and electrochemical action.

The spherical shape of the traces of silicon in the aluminum is believed to transition to the hexagonal shape due to the "free chlorine" of the complex and due to the interaction of the mercury-treated aluminum with the hydrochloric acid solution. Hexagonal holes can be observed in the aluminum, hydrogen and oxygen complex of the invention according to the circumference of the hexagonal silicon crystal. The properties of BB-1 are also believed to be related to a phenomenon that allows the complex of the invention to deliver oxygen and hydrogen in the presence of a catalyst.

When ordinary aluminum is introduced into a hydrochloric acid solution of, for example, IN or 2N, aluminum chloride (and water) is formed. However, when mercury-treated aluminum used in the process of the invention is partially immersed in hydrochloric acid, the behavior is completely different. It is true that aluminum chloride and other aluminum compounds are still formed 870 1 1 4 3 15, but after about 8 to about 72 hours have elapsed a complex forms on the non-immersed surface which starts as a blue-green amorphous material.

The principles, preferred embodiments and applications of the invention described above should not be construed as limiting the invention. Variations and adjustments can be made by those skilled in the art without departing from the essence of the invention.
