Description

A LIQUID AND SPREADABLE BODY CLEANSING MIXTURE RETAINING

RADIONUCLIDES

Technical Field

The invention relates to a body cleansing mixture, which allows the removal from the surfaces of body, of Uranium (U238) radionuclide a highly abundant substance in nature and which contaminates human skin or hair due to the frequency of exposure.

Prior Art

The human body is affected by natural radiation originating from the earth in two ways as internal irradiation and external irradiation. Our whole body is exposed to external radiation due to the gamma rays emitted by the radioisotopes on earth. High radioactivity can mainly be found in volcanic rocks such as granite, phosphate rocks, and sediments. Since construction materials are made of stones and soil, they may have low levels of radioactivity. Therefore, people are exposed to as much radiation inside of the buildings as outside of the buildings. The human body is both exposed to radiation irradiation and contaminated by radionuclides.

Alpha, beta, gamma, X rays, and neutrons that are ionizing radiations, are radioactive in energies that can create ions in humans and other living cells that they impact to. Series of U- 238 and Th-232 and K-40 that emit gamma rays are 3 important detectable components of external radiation. U-238 is the starting source of the long radioisotope decomposition series of many elements and it decomposes until it becomes a stable Pb-206. The radon radioisotope (Rn-222), which is a radioactive gas that is among the first products that is formed, disperses into the atmosphere and continues its decompose.

The odorless, colorless, tasteless radon, which is a noble gas with the atomic number 86 within the periodic table, is formed as a result of the radioactive decomposition of natural uranium comprised in stones, soil, and water. The main atoms of this decomposition chain can be found in all-natural materials. Therefore, radon is dispersed into the environment from all surface stones and soil, and construction materials. Radon decomposition products create radioactive aerosols by attaching to dust and other particles. Therefore, it is possible to inhale these since they are airborne.

Radon exposure is an essential problem considering that people spend most of their time indoors. The soil and stones in the construction of the foundation of buildings are the largest sources of radon. A large part of the radon penetrates the structures through the soil or rocks beneath them. Radon and other gases rise above the ground and entrapped under the construct. The trapped gases create pressure. The air pressure in the houses is generally lower than the pressure in the soil.

The gases leak into the building from the ground through walls, cracks, and gaps due to the high pressure under the building.

Radon can dissolve in water, and especially in underground waters. Typically, one in 10000 of the radon in the water flowing from the tap disperses to the air. The higher the radon amount in the water is, the higher the radon level in the building will be . The trace amount of uranium in the materials used in the construction sector is one of the factors that increase the radon levels in buildings.

It is evident that the natural U-238 radionucleotides that accumulate on the human body should be retained and removed from the human body, especially for the reasons described above. It is clear that these particles that accumulate on the body pose a threat to human health.

The removal of the radioactive particles that accumulate on the body after radiation-borne accidents is another technical problem .

This invention aims to use zeolite ( clinoptilolite ) which has the ability to absorb radionuclides to retain the particles mentioned .

It is known that there are mixtures that include zeolite in the prior art. Mixtures that are used in many different fields such as astringents, sunscreen/suntan lotions, creams/lotions that reduce bad odors, mixtures for mouth cleaning (toothpaste for example), face and body masks, and powder, shampoo, and soaps used in cosmetics can be given as examples to mixtures with zeolite .

For example, in the patent application numbered CN107822933, a cream composition that can also contain zeolite besides many different components that can be used for cosmetic and similar purposes, is described. According to the patent application CN107822933, the cream mentioned is intended to dissolve multiple macro and trace elements beneficial to the human body after continuous contact with water, to produce negative air ions spontaneously and continuously, to benefit the health of the body and to prevent and treat diseases rather than retaining radioactive particles.

In the patent application numbered CN107164123, a soap containing zeolite powder is described. The soap that is subject to the application is made of oil acids, palm oil, propylene glycol, glycine betaine, zeolite powder, chelating agent, and an assistant. The assistant here consists of divaricate saposhnikovia root, licorice root, magnolia flower, and radix sophoraeflavescentis .

The soap that is subject to the patent application numbered CN107164123 does not aim to retain the radioactive particles but aims to create a soap formula with fast bactericide power, high resistance to hard water, safe and environmentally friendly.

The application numbered RU2677882 describes a biologically active zeolite composition that is developed to be used in cosmetics. For example, the composition subject to the patent consisting of zeolite can be used to develop hair dye.

The composition subject to the application numbered RU2677882 does not aim to create a cleansing solution that aims to retain radioactive particles but aims to change the hair color and strengthen the hair. The patent application numbered KR20150053308 describes a shampoo formulation containing natural zeolite and the production method related to this formulation.

The said shampoo mixture contains zeolite as a minor component and includes various components.

Moreover, the shampoo mixture aims to calm anxiety and provide emotional stability. Furthermore, a shampoo mixture with many natural ingredients, and that does not cause secondary side effects and allows long-term use without requiring surface-active agent chemicals was tried to be produced.

The application numbered JPS61293908 describes a cleansing material that contains zeolite used for cleaning hair and skin. The cleansing material is in the powder form. The powder cleansing material foams rapidly when mixed with water.

Alongside aiming to create a calming effect during use, the cleaning material subject to the application number JPS61293908 aims to increase the blood circulation by providing CO2 release.

Application numbered JPS5437841 describes a liquid cosmetic material for washing hair.

With the application numbered JPS5437841; it is aimed to improve the ease of brushing, enhance the deodorizing ability, increase the features that advance reservation stability and softness in liquid cosmetics such as shampoo by mixing certain powders of natural aluminosilicate zeolite and an anionic polymer electrolyte in certain amounts. Application numbered JPS5437841 is not created to retain radioactive particles.

Information about the radionuclide capturing capacity, meaning the adsorption capacity of the zeolite in the mixture, does not exist in the literature thus the use of mixtures containing zeolite with other cosmetic ingredients for radionuclide retention is not known in the prior art. Although in the prior art it is known that zeolites are used for cleaning the wastewater contaminated with radionuclides, this application is intended for a very different area of use.

In zeolite usage when cleaning the radionuclide contaminated wastewater, the wastewater is treated with zeolite fragments, and the fragments loaded with radionuclides are buried.

Zeolite is mixed directly into the water without creating any kind of mixture in these types of applications .

The Problems that the Invention Aims to Solve

The invention aims to create a liquid and spreadable cleansing mixture that contains zeolites in its composition, enabling the removal of the radionuclides contaminating the human body or hair, while washing.

Thus, the user can reduce or completely eliminate the radionuclides that are found in all living areas and, therefore, can accumulate in the human body or hair, with this cleansing mixture .

For example, in the event that the cleansing mixture is in either shower gel or shampoo form, the user can reduce the amount of radionuclides in one's body by using this mixture while having a bath .

The mixture subject to the invention is in the liquid and spreadable form to be able to spread it on the body during a bath or shower. It is essential to maintain the zeolite, which is of the solid form in the mixture, affectivity that is enabled by the pores in the affectivity mechanism. For this reason, in the further phases of the invention, the zeolite added to the mixture is reduced to a certain particle size.

Thus, both a spreadable mixture is obtained, and the effectiveness of the zeolite pores are preserved.

Since the mixture created is used as shampoo, shower gel, and similar body cleansing mixtures, it is an important aim that the components to be added to the composition should not reduce the effect of zeolite but also maintain its cosmetic properties.

It has been revealed that pH is one of the most important variables that have an impact on the mechanism of action of zeolite in a cleaning mixture used for washing. Consequently, it is aimed to create a product formulation whose pH is at the value that the zeolite provides maximum radionuclide adsorption.

Description of the Invention

The invention relates to a liquid and spreadable cleansing mixture, which enables to remove during washing, the radionuclides that contaminate the human body or hair with the help of zeolite in its composition. The said mixture can be described as a shower gel, shampoo, liquid soap, or similar spreadable liquid mixtures.

The preferred formulation of the invention is a cleansing gel. Thus, the benefits from the product can be increased due to surface area, ease of application, effective dosage, and rinsing abilities .

As it is known, zeolite minerals are aluminosilicate compositions consisting of a three-dimensional network of tetrahedral ALSO₄ and Si0₄ that can elongate unlimitedly and can be bound by sharing oxygen atoms. The structure is like a honeycomb or a cage and consists of replaceable cations and water. The total volume of pores (cavities) is between 20-50% of the total mass.

The most important characteristic of zeolite minerals is the structure that can be called a molecular sieve originating from the liquid and gas molecules as well as alkaline-earth ions.

Actually, these pores (cavities) of the zeolite, which is also included in the cleansing mixture subject to the invention, enables the removal of the radionuclides contaminating the human body by retaining the radionuclides.

The zeolite particles, which are liquid and spreadable, will be spread through the surface by rubbing during washing, and radionuclides will be removed from the body by being restrained in these cavities.

Because of this reason, zeolite is granulated and added into the cleansing mixture. The particle (granule) size of the zeolite to be used in the mixture within the preferred embodiments of the invention can be 5-240 pm.

The zeolite granules created within the cleansing mixture can be the same size, or zeolite granules with different particle sizes can be used in the same cleansing mixture to provide different effects .

Another important variable is the pH of the created mixture since the pH of the mixture affects the radionuclide absorption. However, it is evident that the pH of the mixture should not exceed certain limits considering that the created mixture is a cosmetic and a cleansing product.

The mixture is prepared so that the pH is between 5-9, according to one of the preferred embodiments of the invention. Auxiliary ions that increase the adsorption capacity or trigger the ion exchange process can be added to the mixture while keeping the pH as stable as possible within the different embodiments of the invention .

The mixture can be composed of adsorbents (zeolite), surface- active agents, surfactants, nonionic surfactants, emulsifying nonionic co-surfactants, moisturizers , amphoteric surfactants, salt volume enhancers, preservatives, and solvent function components if the said cleansing mixture is a shower gel.

The formulation for said shower gel is presented below.
