Description

{FUNCTIONAL CREAM FOR ULTRA-FINE PARTICLES PROTECTION}

The present invention relates to a functional cream for ultrafine dust barrier comprising a porous mineral and a harmless photocatalyst in order to prevent fine dust from penetrating through pores of skin to induce various skin inflammation including atopy. It is possible to effectively prevent fine dust from entering into the human body through the skin due to the adsorption of fine dust by the porous mineral and the antibacterial effect by the photocatalyst.

Ultrafine dust refers to dust particles having a diameter of 1/400 mm or less, which is the daily average standard value per cubic meter of 50 ㎍ / ㎥ and the annual average standard value is 25 ㎍ / ㎥ in the atmospheric environment standard.

Most of such ultrafine dusts are mostly discharged by artificial factors such as automobile exhaust gas, industrial process, dust blown on roads, and the like.

Since the size of the ultrafine dust is very fine particles smaller than one-twentieth of the normal diameter of the hair, when it enters the human body through breathing, it does not get caught in the nose or bronchus but reaches the lungs, Or it may penetrate into the blood by capillary blood vessels to induce cardiovascular diseases and infiltrate through the pores of the skin to cause various skin diseases including atopy.

Accordingly, the inventor of the present invention has completed the present invention by developing a functional cream for blocking ultrafine dust in order to effectively prevent ultrafine dust from penetrating into the human body through skin and causing various diseases.

Korean Registered Patent No. 10-1055447 (registered on August 2, 2011)

The present invention uses a porous mineral, a harmless photocatalyst and an auditory extract for skin cream in order to prevent ultrafine dust from penetrating into the human body through the pores of human skin, The present invention is intended to provide a functional cream for ultrafine dust barrier which enables the antimicrobial action by the algae extract and the skin protection function by the algae extract.

In order to achieve the above object,

The present invention relates to a method for producing a zeolite comprising 80 to 95 wt% of expandable mineral particles having an average particle size of 10 to 30 μm selected from at least one of elvan, zeolite, ilite and vermiculite,

0.1 to 10 wt% of at least one photocatalyst selected from titanium oxide (TiO ₂ ), ruthenium (Rh) and copper (Cu) having an average particle size of 0.1 to 0.5 μm,

And 0.01 to 10 wt% of a silver nano solution in an amount of 0.1 to 50 wt% based on the total weight of the cream for cosmetics, to provide an ultrafine dust-preventing functional cream.

The fine dust-blocking cosmetic composition according to the present invention has an advantage that it effectively blocks the fine dust in the air, thereby solving the problem of penetrating the skin through the pores to cause skin diseases.

Also, the adsorption of fine dust effectively occurs due to the heavy metal and fine dust adsorption function by the expansive minerals and the catalyst, and the reliability of the product can be increased.

In addition, it has an effect that the functional properties of a cosmetic such as skin moisturizing can be improved by constituting a cosmetic using natural hearing ingredients.

Hereinafter, the technical contents of the above description will be described in detail.

As described above, the functional cream for blocking ultrafine dust according to the present invention comprises 80 to 95 wt% of expandable mineral particles having an average particle size of 10 to 30 μm selected from at least one of elvan, zeolite, ilite and vermiculite,

0.1 to 10 wt% of at least one photocatalyst selected from titanium oxide (TiO ₂ ), ruthenium (Rh) and copper (Cu) having an average particle size of 0.1 to 0.5 μm,

And a silver nano solution in an amount of 0.1 to 50 wt% based on the total weight of the cream for cosmetics.

If the amount of the expansive mineral particles is less than 80 wt%, the adsorption functionality of the micro-tiny particles tends to deteriorate and it is difficult to achieve the object of the present invention. When the amount exceeds 90 wt%, the amount of the other components is reduced, The function as a functional cream may be deteriorated. Accordingly, the amount of the expandable mineral particles is preferably limited within a range of 80 to 95 wt% with respect to the total weight of the ultrafine dust-blocking composition.

Among the above-mentioned inflatable minerals, the elvan has the function of adsorbing by porosity, precipitation of minerals, controlling the quality of water, increasing the amount of dissolved oxygen in water, and is widely used for bath water, cosmetics, medicinal toothpaste, It is used for external medicine.

When the granite is extracted as a fine powder having a particle size of 325 mesh or less and its grain is observed by an electron microscope, it can be seen that it is very porous like a coral reef or sea surface. This property of porosity is closely related to mineral elution, physical and chemical adsorption, ion exchange, and so on.

In this way, the porous nature of the elvan increases the surface area, attracting adsorbed atoms to the surface of the solid catalyst by intermolecular reaction, and precipitating by the action of (+) ion and (-) ion, Due to physical adsorption or chemical adsorption.

The zeolite is an aluminosilicate. The basic skeleton of the crystal is a tetrahedron composed of silicon and aluminum in coordination with oxygen, and is composed of a primary constituent unit. The reason why zeolite has selective adsorption characteristics is that the tetrahedral structures of silica and alumina are gathered so that these tetrahedrons are connected three-dimensionally to make space, and water And cations. This space is dehydrated at a high temperature and a low pressure to form an empty space, and the porous material having an inner surface area becomes large. The material that is larger than the inlet of the pores in the space can not pass through and the size of the inlet serves as the molecular sieve. This is why zeolite is used as the adsorbent because of the molecular sieve.

The ilite has a chemical composition of (K, H ₃ O) Al ₂ (Si, Al) ₄ O ₁₀ (H ₂ O-OH) ₂ and has a hardness of 1 to 2 and a specific gravity of 2.6 to 2.9. Illite is divided into white-ilite and yellow-ilite depending on the color. White-yellow light is one-one is contained less than the SiO ₂ is more and _{Al 2 O 3, Fe 2 O} 3, K 2 O light. In addition, Illight exhibits similar properties to muscovite. When compared to muscovite and Illight, Illight has more Si, Mg, and H ₂ O and less Al and interlayer K in tetrahedra. Illite formed by discontinuous property action has 0.75 K ions per T ₄ O ₁₀ (OH) ₂ unit structure between layers. Less interlayer cations than mica are due to less layer charge of mica or fenzyme than mica. Its multi-formwork is the same as muscovite.

More specifically, the aforementioned ilite is used having a particle size (m) of 1 to 15, a pH of 7.0 to 9.0 (neutral) and a specific surface area (m 2 / g) of 2 to 15.

The vermiculite is also called vermiculite and refers to a functional mica, which is generally a product of alteration of phlogopite or biotite. The structural formula is a clay mineral with a three - layer structure similar to biotite with the form of Mx (Mg, Fe) ₆ (Si ^- _x Alx) O ₂₀ (OH) yH ₂ O. When the vermiculite is heated and expanded, it expands to about 6 to 20 times depending on the condition of the heat treatment and the nature of the raw material.

The most important advantage of expanded vermiculite is that it is cheaper than existing activated carbon and there is a space that can be adsorbed between plate and plate like existing activated carbon.

The vermiculite is a generic name for a steel-aluminum-silicate mineral which has a similar appearance to the mica in its natural state. It is used in various fields industrially using the property that it expands when heated. When heated to 900-1000 ° C, the moisture between the layers turns into steam and the lattice layer swells up or separates into worms. The volume can increase up to 30 times for individual pieces that are 8 to 20 times larger in commercial quality. When expanded, it has optimal insulation properties at low density and has good absorption and ion exchange capacity. It is chemically non-toxic and stable.

Among the above photocatalysts, titanium oxide has an antibacterial action against various infectious substances contained in ultrafine dusts, and is chemically stable, harmless to the environment, and non-toxic to living organisms.

As described above, at least one selected from titanium oxide (TiO ₂ ), ruthenium (Rh) and copper (Cu) is used as the photocatalyst. When the amount of the photocatalyst used is less than 0.1 wt% The amount of the expandable mineral particles may be reduced and the adsorption functionality of the ultrafine dust may be lowered. Therefore, the amount of the titanium oxide used is preferably 0.1 to 10 wt% based on the total weight of the ultrafine dust- Of the total amount of water.

In the case of the TiO ₂ photocatalyst, due to several characteristics, it has been recognized as an excellent performance in the decomposition reaction of pollutants and has received great interest as a catalyst for purification. First, the pollutant decomposition reaction is mostly oxidation reaction, and the second is the chemical optical stability of TiO ₂ . The green technology utilized maximizes the catalytic activity by using a TiO ₂ photocatalyst and an ultraviolet lamp of 254 nm wavelength, and generates O ₃ by using an ozone generator to oxidize contaminants. The infrared lamp used is one, the output is 50 W, and emits infrared rays in the near infrared region of 800 nm to 1,000 nm. The role of infrared wavelengths in this technology is to act as a catalyst when odorous and contaminant molecules are activated by energy and cause oxidation reactions with OH radicals. Some research has been conducted on the emission of infrared rays according to the variation of each wavelength. In this case, as a basic study for the development of noninvasive blood glucose analysis method using near infrared rays, the injection amount of 700 nm ~ 1,100 nm was investigated and it showed a rise efficiency of 900 ~ 1,100.

When TiO ₂ absorbs ultraviolet light of 388 nm or less, e _cb ^- in the CB (conduction band) and h _vb ⁺ in the VB (valance band) are generated. These fishes, _hvb ⁺ , react with the OH groups on the TiO ₂ surface to form OH radicals, which are powerful oxidants. Except for some exceptional cases, almost all organic pollutants are decomposed by oxidation reaction with OH radicals. do. The contaminants adsorbed on the TiO ₂ surface are oxidized and decomposed by OH radicals, and the principle of decomposition is the same as the reaction through OH radical formation (Eqs. (1) to (6)).

TiO ₂ + h _v → h _vb ⁺ + e _cb ^- (1)

Substrate + h _vb ⁺ → Oxidized substrate (2)

_{^{≡Ti-OH - + h vb +}} → ≡Ti-OH · (3)

^{_{H 2 O + h vb + →}} OH · + H + (4)

_{^{OH - + h vb + → OH}} · (5)

Substrate + OH · → Oxidized Substrate ( 6)

In addition to the above-described photocatalyst, the photocatalyst may include 50 to 80 wt% of titanium oxide (TiO (OH) ₂ ); It is also possible to use an alternative catalyst composed of a mixture of 20 to 50 wt% of expandable mineral particles selected from quartz or zeolite.
