Description

Extraction method for functional cosmetic composition containing fucoidan component and functional cosmetics using same

The present invention relates to a method for extracting a functional cosmetic composition containing a fucoidan component and to a functional cosmetic manufactured using the same.

Fucoidan is a type of polysaccharide contained in brown algae such as kelp and seaweed, and is a dietary fiber known to be effective in preventing aging. It refers to a high molecular weight sulfated polysaccharide (molecular weight about 200,000 Daltons) rich in fucose contained in various types of brown algae such as seaweed, kelp, and seaweed. was found

Fucoidan is largely divided into Australian Mechab Fucoidan and Okinawa Mozuku Fucoidan.

Mecca fucoidan produced in Australia is extracted from wild seaweed grown in clean areas, and is recognized as a high-quality raw material for fucoidan that has been certified organic by the US USDA. And seaweed-gwi-mekab (Undaria pinnatifida) is a Japanese term for the sporophyte, which is the germ of seaweed, and corresponds to the stem part close to the root of seaweed. However, among seaweed, fucoidan is concentrated only in this mechave part. As a characteristic of mechav fucoidan, it contains more than 34% of sulfate groups.

Mozuku Fucoidan is produced in the clean area near Okinawa, the southernmost tip of Japan. Okinawa Island is an island closer to Taiwan than the mainland of Japan. It is a very clean and clean area with no worries about radioactivity, and is also famous as a longevity village. Mozuku (Cladosiphon okamuranus) fucoidan is most famously extracted from mozuku from Okinawa, Japan. Mozuku fucoidan, which is easy to extract and is the most widely used among fucoidans, has been reported to have a special effect compared to other fucoidans.

Since seaweed has a harder algae and cell wall than terrestrial organisms, it is difficult to obtain useful components when simple treatments such as general organic solvents, enzyme treatment, and sonication are used, odor and taste are generated, and low yield and high cost are required. .

In particular, the brown algae from which fucoidan was extracted was kelp. However, compared to other brown algae, kelp contains a relatively small amount of fucoidan, and the extraction cost is high, making it difficult to mass-produce from an economic point of view.

In addition, the existing seaweed extraction fucoidan manufacturing process uses extraction of fine powder and organic solvents (acetone, isopropyl alcohol, ether, alcohol, etc.) without a pre-treatment process to separate fine powder and extract (centrifugation), and separate/purify organic solvent from the extract. This process is essential, so it consumes a lot of time and money because there are many processes, and it is also derived from food safety issues in the separation/purification of organic solvents.

Conventional fucoidan extraction was extracted from seaweed such as seaweed and kelp, but the conventional fucoidan extraction method is raw material → raw material grinding → purified water stirring chuck) → extraction → filtration → separation/purification → concentration → coagulation → alcohol removal → freeze-drying → pulverization Fucoidan was extracted from seaweed through many steps such as → quality inspection (separation) → packaging.

In Korea, it is a condition of the topography of the peninsula where seaweeds can be used abundantly since ancient times. Therefore, it has very favorable conditions for the production of seaweed, and the seaweed-related industry has been active since ancient times.

Tot is a kind of brown algae belonging to the family Mosaidae. It is also called Nokmichae (鹿尾菜) because the shape of its growth resembles that of deer antlers. Hijiki (ひじき) in Japanese. Tot is mainly native to Northeast Asia, namely Korea, China, and Japan. It has been eaten since ancient times, and in Jeju Island, it was often eaten as a gourd food when there was a famine. The harvest season is from March to May. In the past, it was distributed at a low price, but it is known to be good for anemia because it is rich in various inorganic salts such as iodine, calcium, iron, sodium, magnesium, and phosphorus. In recent years, it has been treated as a health food and its price is rising.

However, less than 10% of hibiscus produced mainly in Wando and Jindo in Jeju and Jeollanam-do is consumed domestically and exported to Japan at a low price.

The development and production of a method for extracting a vegetable cosmetic composition containing fucoidan using seaweeds such as shiitake algae and the development and production of functional cosmetics using the same, along with the industrial development of the cosmetic field, increase the income and export expansion of fishermen in Jeju Island who collect seaweed such as shiitake algae. The effect is expected to be expected.

The main components of fucoidan include fucose, galactose, xylose, and mannose, which are monosaccharides, and uronic acid (glucronic acid) and sulfate group, which are carboxyl groups. And the five major constituent indicators of fucoidan are 'fucose', 'glucose', 'xylose', 'calactose' and 'sulfuric acid group', and the quality of fucoidan is determined according to its content. However, the reality is that there is no official measurement method for fucoidan yet. As a result, each company tends to indicate the purity of fucoidan in their own way. To date, as the most reasonable method for measuring the purity of fucoidan, a method of measuring the total amount of components such as carbohydrates, sulfate groups, and cations has been proposed. By checking how many grams of fucoidan contained in the whole product is, the functional cosmetic composition containing 85% by weight of fucoidan is found to be the most effective. Extracted so that the fucoidan component is 85% by weight or more A way was needed.

Since fucoidan is generally a polymer having a molecular weight exceeding 300 kDa, fucoidan in a polymer state is not properly absorbed by the skin, and fucoidan in a polymer state is highly viscous. There is a problem in that the viscosity is greatly increased.

As related technologies, high yield that improves the extraction yield and the purity of fucoidan indicator substances (fucose, glucose, xylose, galactose, sulfate group) using kelp among seaweeds through Korean Patent Publication No. 10-2014-0086445, A technology for a method for producing high-purity fucoidan has been proposed.

The above-described technical configuration is a background technique for helping understanding of the present invention, and does not mean a conventional technique widely known in the art to which the present invention pertains.

The brown algae from which fucoidan was extracted was kelp. However, compared to other brown algae, it contains a relatively small amount of fucoidan, and the extraction cost is high, so mass production is difficult from an economic point of view.

Therefore, there is a need to improve it.

In one aspect of the present invention, washing the vegetable cosmetic raw material; drying the washed vegetable cosmetic raw material; adding a solvent 10 times to 1,000 times the weight of the washed and dried vegetable cosmetic raw material and heating at 100° C. to 180° C. for 5 hours to 10 hours to extract primary hot water; first filtering the hot water extract; precipitating the first filtered hot water extract to obtain a supernatant; reheating the supernatant at 50° C. to 150° C. to extract secondary hot water; And it is an extraction method of a functional cosmetic composition containing a fucoidan component comprising the step of secondary filtration of the hot water extract.

Hereinafter, a method of extracting a functional cosmetic composition containing fucoidan in an embodiment of the present invention can be described with reference to FIG. 1 .

First, a vegetable cosmetic raw material is prepared and washed (S10).

In the next step, the sieved vegetable cosmetic raw material is dried (S20).

As an embodiment, the vegetable cosmetic raw material can be used without limitation, seaweed containing a fucoidan component among plant raw materials that can be used as a cosmetic composition, specifically, extracted from one or more of seaweed, seaweed, seaweed, kelp or shiitake. ingredients are available. Preferably, a component extracted from chives may be used.

In one embodiment, the drying may include freeze drying, spray drying, or hot air drying. Specifically, the vegetable cosmetic raw material may be dried through freeze drying, spray drying, or hot air drying so that the mass of moisture compared to the vegetable cosmetic raw material is 1% to 15%. More specifically, it may be dried so that the mass of moisture compared to the vegetable cosmetic raw material is 0.5% to 8%.

In one embodiment, the method may further include cutting or pulverizing the washed and dried vegetable cosmetic raw material. For example, the washed and dried vegetable cosmetic raw material may be cut to be well immersed in a solvent during hot water extraction or may be pulverized into a powder state of about 50 mesh or more, but may not be limited thereto.

Next, the primary hot water extraction is performed by heating by adding a solvent of about 10 times to about 1,000 times the weight of the raw material for the vegetable cosmetics (S30). More specifically, it may be heated by adding about 10 times to about 500 times the solvent.

In one embodiment, the present invention includes distilled water, ethanol, organic acid, a platinum catalyst, and germanium oxide powder as solvents, and thus may have an effect of preventing a phenomenon in which mutation occurs in the extract after conventional hot water extraction.

In one embodiment, the solvent is, based on 100 parts by weight of the solvent, about 40 to about 80 parts by weight of distilled water, about 10 to about 30 parts by weight of ethanol, about 5 to about 10 parts by weight of organic acid, and about 0.5 to about platinum catalyst It may contain 3 parts by weight.

In an embodiment, the organic acid may be used without limitation among organic compounds exhibiting acidity that are harmless to the human body. For example, acetic acid, butyric acid, citric acid, palmitic acid, oxalic acid, tartaric acid, glycolic acid, It may include one selected from the group consisting of lactic acid, maleic acid, and combinations thereof. Preferably, it may be one containing oxalic acid.

In one embodiment, according to the content of the organic acid, the component variation of the functional cosmetic raw material obtained after the extraction may be prevented. For example, the pH of the solvent is changed by the content of the organic acid, which affects the stability of the cosmetic raw material, and as a result, may serve to prevent the cosmetic raw material from being changed.

In one embodiment, the content of the organic acid may be about 3 to about 7 parts by weight based on 100 parts by weight of the solvent. When the content of the organic acid is less than about 3 parts by weight or more than about 7 parts by weight, the pH of the solvent is rapidly changed and the extraction yield may decrease. Therefore, the content of the organic acid may be about 3 to about 7 parts by weight, preferably about 5 to about 7 parts by weight, based on 100 parts by weight of the solvent.

In one embodiment, the platinum catalyst is a platinum carbonyl cyclovinylmethylsiloxane complex, a platinum divinyltetramethyldisiloxane complex, a platinum cyclovinylmethylsiloxane complex, a platinum octanaldehyde/octanol complex, and combinations thereof. It may include one selected from.

As an embodiment, when the platinum catalyst is included in less than about 0.3 parts by weight, the effect that may appear as the platinum catalyst is included, specifically, the effect of improving the extraction yield may not be sufficiently exhibited, and it exceeds about 2 parts by weight Since unnecessary precipitates may be generated by the platinum catalyst when included as there is. Preferably, it may be included in an amount of about 0.3 to about 0.7 parts by weight.

In one embodiment, the solvent may include germanium oxide powder. Germanium is a grayish-white ceramic with an atomic weight of about 72.59, and mainly exists in the form of divalent or tetravalent compounds. Since germanium exhibits semiconductor properties, it may be used in optical fibers and chemical catalyst fields, but may not be limited thereto.

In one embodiment, the germanium oxide may be prepared by hydrolyzing germanium chloride obtained from germanium ore, for example, germanium oxide (GeO) or germanium oxide (GeO2).

In one embodiment, in the extraction method, as the solvent contains germanium oxide powder in an amount of about 0.8 to about 3 parts by weight based on 100 parts by weight of the solvent, the yield of the hot water extraction may be increased. Specifically, as the germanium oxide powder is used together with the platinum catalyst, the yield of hot water extraction may be increased compared to the extraction method using the germanium oxide powder or the platinum catalyst alone, but may not be limited thereto.

As an embodiment, when the germanium oxide powder is included in less than about 0.8 parts by weight, the extraction yield may not be significantly improved, and when it is included in excess of about 3 parts by weight, unnecessary precipitate may occur, so the germanium oxide powder is It may be included in an amount of about 0.8 to about 3 parts by weight, about 1 to about 3 parts by weight, or about 1.5 to about 3 parts by weight based on 100 parts by weight of the solvent. Preferably, it may be included in 1.5 or 2 parts by weight.

The primary hot water extraction may be performed at a temperature at which the active ingredient of the vegetable cosmetic raw material can be dissolved in the solvent, and specifically, may be performed at a temperature ranging from about 100°C to about 180°C. When the primary hot water extraction is performed at less than about 100 ° C, the active ingredient contained in the vegetable cosmetic raw material may not be sufficiently dissolved in the solvent, and when it is carried out above about 180 ° C, the component of the vegetable cosmetic raw material is may vary, the solvent may contain an unpleasant odor, or the solvent may all be vaporized before hot water extraction has sufficiently occurred. Therefore, the primary hot water extraction is from about 100 °C to about 180 °C, from about 100 °C to about 150 °C, from about 100 °C to about 130 °C, from about 130 °C to about 180 °C, from about 130 °C to about 150 °C, or from about 150 °C It is preferably carried out at a temperature of about 180 °C to about 180 °C.

As an embodiment, the primary hot water extraction may be performed until about 50% of the initial volume to which the solvent is added, and specifically, may be performed for about 1 hour to about 24 hours. Specifically, it may be carried out for about 5 to 10 hours, preferably 6 to 8 hours.

Next, the hot water extract obtained after the first hot water extraction is first filtered (S40) to remove unnecessary impurities and bacteria.

As an embodiment, the primary filtration may be performed using filter paper. For example, the filter size of the filter paper may be 0.1 μm to 2.0 μm, but preferably 0.1 μm to about 0.8 μm.

Next, the first filtered hot water extract is precipitated for a predetermined time to obtain a supernatant (S50).

As an embodiment, it may include adding a solvent to the precipitate obtained after the precipitation and extracting with hot water again.

In this case, the solvent may be the same as that of the primary hot water extraction, but may be performed in a shorter time than the primary hot water extraction.

In one embodiment, centrifugation may be used in the step of precipitating the first filtered hot water extract to obtain a supernatant, but may not be limited thereto.

Next, by re-heating the supernatant obtained by precipitation to extract the secondary hot water (S60), the active ingredient of the vegetable cosmetic raw material composition not extracted in the primary hot water extraction is re-extracted.

As an embodiment, the secondary hot water extraction may be performed at a lower temperature than the primary hot water extraction. For example, the secondary hot water extraction may be performed at about 50° C. to about 150° C., specifically, about 50° C. to about 120° C., about 50° C. to about 85° C., about 85° C. to about 120 ℃, or may be carried out at about 120 ℃ to about 150 ℃, may not be limited thereto.

In this case, the secondary hot water extraction may be performed in a shorter time than the primary hot water extraction, but may not be limited thereto.

As an embodiment, after the secondary hot water extraction, additional hot water extraction may be performed to improve the extraction yield of the hot water extract. The number of additional hot water extraction may be different depending on the type of vegetable cosmetic raw material used, for example, may be additionally performed 2 to 4 times, but may not be limited thereto.

Next, by secondary filtration (S70) of the hot water extract obtained after the secondary hot water extraction, impurities not removed in the primary filtration are removed to obtain a cosmetic raw material. The secondary filtration may be performed through the same or different method as the primary filtration, and specifically may be performed using a filter paper of a smaller filter size than the filter paper used in the primary filtration.

As an embodiment, the secondary filtration may be performed using filter paper. For example, the filter size of the filter paper may be 0.05 μm to 1.0 μm, but preferably 0.05 μm to about 0.5 μm.

In one embodiment, in the functional cosmetic composition extracted by the extraction method, the molecular weight of the fucoidan component may be 1,000 Da or less. Specifically, it is preferably 800 Da.
