Cosmetic composition containing heat-treated activated carbon as an active ingredient and a method for preparing the same {Cosmetic composition containing heat-treated active carbon as an active ingredient and method for producing the same}

1 is a schematic diagram of the pore structure of activated carbon.

The present invention relates to a cosmetic composition containing activated carbon and a method for producing the same. More specifically, the present invention relates to a cosmetic composition that can significantly increase the effect of removing waste matter such as excess sebum, old dead skin, dust, etc. present on the skin by containing activated carbon which has significantly improved adsorption power through heat treatment. In addition, the present invention relates to a cosmetic manufacturing method that can prevent the blowing or agglomeration that can occur during the production of a cosmetic composition containing activated carbon and prevent the problem of activated carbon is precipitated in the cosmetic formulation.

In general, human skin is covered with sebum, sweat, dust, dead skin cells and various cosmetic residues. In particular, during high summer temperatures or during puberty when hormone secretion is active, acne or seborrheic dermatitis may be caused by excessive secretion of sebum.

The skin that all women expect is expected to bring the elasticity of the skin by keeping the moisture on the surface of the skin at a certain level while smoothly discharging sebum, etc., which cannot be discharged to the skin surface to the outside to maintain clean skin at all times. It can be said to enhance the effect of beauty.

The present invention has been devised to solve such problems more effectively. Purifying, cleaning, and moisturizing various cosmetics by utilizing the adsorption and moisturizing functions of charcoal, which has been widely used as a tablet, antidiabetic, antidote, etc. The purpose is to provide a new cosmetic composition that enhances the effect. The charcoal's excellent adsorption power is due to its large surface area and its numerous pores of various sizes produced in the process of making charcoal. The pores of cells and cell walls of wood used as charcoal are carbonized, It is formed, due to the role of a large amount of formed micropores will be due to the increase in the adsorption power and moisturizing function.

There have been several examples of the use of charcoal powder in cosmetics. However, these cosmetics had a problem that the charcoal powder is settled to sink to the bottom, the charcoal powder is blown and agglomerated with each other during the manufacturing process. The biggest problem was that the charcoal powder itself has a property of coloring black, so when used in cosmetics, it can be countered to skin beauty. For this reason, the conventional charcoal powder-containing cosmetics have limited the amount of charcoal powder used, and therefore, it is difficult to expect a sufficient adsorption effect.

The present invention is to solve the above problems, it is an object of the charcoal powder to be able to remove the skin impurities with excellent adsorptive power without coloring the skin black. In addition, it is an object of the present invention to solve the problems of poor workability, such as dusting or agglomeration of charcoal powder during the manufacture of cosmetics. In addition, the present invention is characterized in solving the problem of formulation stability unique to charcoal powder in which the charcoal powder is precipitated in the cosmetic formulation.

In order to achieve the above object, the cosmetic composition according to the present invention is characterized in that the activated carbon obtained by heating 60 to 80 minutes at a temperature of 900 to 1000 ℃ as an active ingredient.

In the cosmetic composition according to the present invention described above, it is preferable to further contain an acrylate / C10-30 alkyl acrylate crosspolymer in an amount of 0.1 to 10% by weight as a viscosity modifier.

In the cosmetic composition according to the present invention described above, it is preferable that the composition is a cosmetic that functions to remove waste products from the skin.

In the cosmetic composition according to the present invention, the composition is a pack of wash-off type, pack of peel-off type, pack of sheet type, cleansing cream, cleansing lotion, cleansing water, cleansing oil, cleansing foam, massage cream and It is preferred to be a cosmetic of the formulation selected from the group consisting of body cleansers.

In the method for producing an activated carbon-containing cosmetic composition according to the present invention, the activated carbon is a heat treated activated carbon obtained by heating activated carbon at a temperature of 900 to 1000 ° C. for 60 to 80 minutes, and the heat treated activated carbon is butylene glycol and A first step of dispersing by adding to one or more polyhydric alcohols selected from the group consisting of glycerin; A second step of mixing materials other than activated carbon; And a third step of mixing the activated carbon dispersed in the polyhydric alcohol in the first step into a mixture of the material prepared in the second step.

In the method for producing an activated carbon-containing cosmetic composition according to the present invention, in the second step, it is preferable to add microcrystalline cellulose in an amount of 0.1 to 10.0% by weight of the total composition.

In the above-described activated carbon-containing cosmetic composition according to the present invention, in the second step, it is preferable to add an acrylate / C10-30 alkyl acrylate crosspolymer in an amount of 0.1 to 10.0% by weight of the total composition as a viscosity modifier. .

In the activated carbon-containing cosmetic composition according to the present invention, in the first step, it is preferable to add the heat treated activated carbon to the polyhydric alcohol and to disperse it with a three-stage roller.

Hereinafter, the cosmetic composition and a manufacturing method thereof according to the present invention will be described in more detail.

The activated carbon used in the present invention is preferably used by heating activated carbon commercially available as a fine powder at a temperature of 900 to 1000 ° C. for 60 to 80 minutes. When the heat treatment was performed for less than 60 minutes, the specific surface area increase rate was less than 9%, so it was hard to expect a sufficient adsorption capacity improvement effect. Moreover, when heat-processing for more than 80 minutes, there exists a problem which ash generate | occur | produces. On the other hand, in the case where the heat treatment temperature is lower than 900 ° C., no matter how much the heating time is increased, the specific surface area is not greatly influenced, and thus sufficient adsorption force is difficult to be expected. In addition, even when the heat treatment temperature exceeds 1000 ° C., the specific surface area increase rate is less than 9%, and when heated for 20 minutes or more, there is a problem that ash occurs.

Typical activated carbons have an inner surface area of 500-1500 m ² / g. As shown in Figure 1, the pore structure of activated carbon is divided into micro-pores, meso-pores, macro-pores. A pore having a diameter of 20 kPa or less is called a micro-pore, and a pore having a diameter of 20 to 1000 kPa is called meso-pore. On the other hand, pores with a diameter of 1000 mm 3 or more are called macro-pores. The pore where adsorption takes place primarily is meso-pores having a diameter of 20 to 1000 mm 3. Macro-pores with diameters of 1000 mm or larger have only secondary importance in practical adsorption processes. Specifically, macro-pores serve as passages for adsorbing solutes from liquids.

When the activated carbon is heated at 900 to 1000 ° C. for 60 to 80 minutes as in the present invention, the specific surface area of the meso-pores in the pores of the activated carbon is increased by 9 to 12%. As the specific surface area of the meso-pores rises, the adsorption capacity in the meso-pores increases significantly, thereby improving the overall adsorption capacity of the activated carbon. If the heating temperature is lower than 900 ℃, the increase of specific surface area is only 3 ~ 5%, no matter how much the heating time is increased, and the increase in specific surface area is only 2 ~ 3% even when heat treatment is over 1000 ℃. There is a problem that ash occurs when heated for 20 minutes or more.

The cosmetic composition according to the present invention preferably contains 1.0 to 50% by weight of the heat treated activated carbon. If it is less than 1.0% by weight, the effect of adsorption power is insignificant, and if it exceeds 50% by weight, problems of formulation stability or black coloration may occur.

It is preferable that the cosmetic composition by this invention contains 0.1-10.0 weight% of microcrystalline cellulose further. If less than 0.1% by weight, the effect of increasing the specific gravity is insignificant, the effect of preventing precipitation of activated carbon powder is insignificant, and if it exceeds 10% by weight, the specific gravity is too high.

The cosmetic composition according to the present invention preferably further contains 0.1 to 50% by weight of at least one polyhydric alcohol selected from the group consisting of butylene glycol and glycerin. If the amount is less than 0.1% by weight, the effect of anti-flouring or agglomeration is insignificant, and if it exceeds 50% by weight, problems in formulation stability may occur.

The cosmetic composition according to the present invention preferably further contains an acrylate / C10-30 alkyl acrylate crosspolymer in an amount of 0.1 to 10% by weight as a viscosity modifier. If less than 0.1% by weight, the viscosity control effect is insignificant, and if it exceeds 10% by weight there is a problem that the viscosity is excessively high.

On the other hand, the cosmetic composition according to the present invention is preferably prepared by preparing the activated carbon powder separately from other materials at the time of manufacture and then mixing the two, when the activated carbon powder is mixed with the remaining materials as it is, activated carbon powder is blown or aggregated Losing problems occur. In order to prevent this, it is preferable to add the activated carbon powder to butylene glycol or glycerin in advance, stabilize and disperse well, and then mix the stabilized activated carbon powder with the remaining materials. At this time, it is preferable to use a three-stage roller to evenly disperse. Butylene glycol and glycerin provide a moisturizing power to the skin, and thus the cosmetic composition according to the present invention may exhibit moisturizing power. In addition, butylene glycol and glycerin are viscous, so that they can be dispersed during treatment with a three-stage roller.

In addition, the cosmetic composition according to the present invention, prior to mixing the activated carbon powder and other material mixture, before mixing the activated carbon powder and other material mixture, in order to prevent the problem of precipitation of activated carbon powder after the preparation of the cosmetic formulation, It is desirable to raise it. In order to increase specific gravity, it is preferable to add microcrystalline cellulose to a material mixture other than activated carbon powder. When the microcrystalline cellulose is added, the specific gravity of the mixture is increased, and thus, precipitation of activated carbon powder added later can be prevented at the source.

On the other hand, in the cosmetic composition according to the present invention, activated carbon particles can be suspended in three dimensions by using an acrylate / C10-30 alkyl acrylate crosspolymer instead of a carbomer commonly used for controlling the viscosity, activated carbon powder To prevent precipitation.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments of the present invention, which is merely for exemplary purposes and is not intended to limit the scope of the present invention.

Then, in order to determine the change in adsorption power with heating time, ordinary activated carbon having an inner surface area of about 100 m ² / g was applied at 950 ° C. for 40 minutes, 50 minutes, 60 minutes, 70 minutes, 80 minutes, 90 minutes, respectively. Heated for 100 minutes. Separately, heat treatment was performed at 860 ° C. for 240 minutes, and separate heat treatment was performed at 1050 ° C. for 20 minutes. After each heat treatment, the adsorption power of each activated carbon was measured.

Measurement of the adsorption force was carried out through the measurement of iodine absorption.

Iodine adsorption capacity measurement is a method of measuring the adsorption performance of activated carbon, the higher the pore-developed activated carbon, the higher the iodine adsorption capacity, which means that the ability to adsorb the substance to be adsorbed. In this experiment, iodine adsorption was measured under the following conditions.

A) Appliances and devices

(1) shaker

(2) Centrifuge: capable of rotating more than 2,000rpm of centrifuge tube with a capacity of 50ml

B) test

0.5 g (in terms of dry weight) of the sample passed through the KS No. 200 sieve was crushed well and placed in a 100 ml stoppered brown Erlenmeyer flask, and 50 ml of 0.1 N iodine solution was correctly added and shaken in a shaker for 15 minutes. Subsequently, it is placed in a centrifuge tube and centrifuged at 2,000 rpm for 5 minutes. 10 ml of this supernatant is placed in a 100 ml beaker and titrated with 0.1 N sodium thiosulfate solution. If brown color turns pale yellow, add 3 ~ 4 drops of starch solution and continue titration until the blue color disappeared. The iodine adsorption capacity (mg / g) is calculated by the following equation from the appropriate aroma (a ml) of 0.1 N sodium thiosulfate solution consumed.
