Description

[0001] The present invention relates to a method for manufacturing a mask pack,

More particularly, the present invention relates to a method for producing cosmetic compositions for mask packs, and more particularly, to a cosmetic preparation method for extracting cosmetic pearlescent extracts from fresh water pearls using vacuum low temperature extraction and distillation extraction, , It is possible to minimize the loss of material-specific nutrients and ensure the safety of the material, prevent secondary skin troubles caused by organic solvents, and contain pear conchiolin extract using ultrapure water capable of protecting skin by antioxidant substances And a method for producing a cosmetic composition for a mask pack.

In general, cosmetic packs used for beauty are applied to the user's face, arms, legs and neck for a certain period of time and then peeled off, thereby expanding the pores of the skin and giving whitening and moisturizing effects to the skin, It is used as one of the skin care methods.

Especially, among the skin beauty packs, the most representative pack for managing the skin of the face is a beauty mask pack, which is used to supply the nutrients to the face surface and to apply a lot of pack agent to make the facial skin beautiful. In other words, when the skin is rough, sunburned or fatigued, a suitable pack is selected, and the face is covered to temporarily block the outside air to improve the cosmetic effect.

These cosmetic packs include a method of using natural vegetables and fruits such as potatoes, cucumbers, and eggs, a method of kneading and mixing ingredients such as eggs, milk, and honey in flour, a method of impregnating a nonwoven fabric with a moisturizer or a nutrient, A mask pack to be sold by the user, and a gel container in a tube container or a cosmetic container.

The pack using the vegetables or fruit described above is disadvantageous in that it is difficult for the user to manage the skin due to the inconvenience that the user is required to slice the skin thinly and the water is evaporated due to exposure to the outside, There is a problem that it is troublesome for the user to use the kneaded product because the kneaded product must be manufactured by the user. Also, in the case of a gel-type pack sold on the market, there is a problem that the user wears the pack and then wipes it off with a cleanser or a tissue when removing the pack later. This makes the user generally prefer a simple and effective mask pack.

The mask pack is generally formed by impregnating a face-shaped sheet made of plant cellulose fiber or nonwoven fabric made of synthetic fiber from a cotton or pulp with a cosmetic composition such as a moisturizer or a nutrient have. In this case, various feeling and efficacy can be given according to the material, kind, and raw materials of the applied nonwoven fabric. In addition to the fibrous nonwoven fabric, various and unique supports can be used as the fresh water body of the cosmetic liquid. Various materials are being studied. Such a mask pack can be attached to a user's face to absorb the cosmetic composition into the face of the user, which is advantageous in that the use method is simple, the cosmetic composition does not flow down during use, and the user can easily remove the cosmetic composition after use. I am using it.

The conventional cosmetic composition to be impregnated into the mask pack is described in Korean Patent Registration No. 10-1156220, which is a method for producing functional kite, which is a method for producing a functional kite which is made from fine algae and land plants A process for removing sea rust, seaweed, and salt from water by cold water and drying it; Dried seaweeds, seaweeds and seaweeds into water, dewatering and concentrating; Chrysanthemum, Boryeong, Saururus chinensis, Kwakyeong, Chunggung, and licorice are washed with water and drained and immersed in a concentrate of the previous process, followed by warm air drying; It consists of a continuous milling of the dried blend into a fine powder. In such a conventional art, merely using algae has a limitation in that skin whitening and wrinkle-reducing effects can be seen while the beauty mask pack is being used, and in order to manufacture and distribute mask packs using natural algae, There is a problem that the preservative must be used for this purpose. In addition, there is a problem that when a pack is used without knowing that a consumer is changed, skin trouble may be caused.

Another prior art is Korean Patent No. 10-2011-0133898, which discloses a sol-type cosmetic mask making method including alginic acid and a cosmetic mask, which comprises preparing a mask film to be removed when using a cosmetic mask step; Providing a mask for forming a mask in the form of a mask on a film of the mask; Applying a composition in the form of a sol containing a functional ingredient and alginate to a tray for mask fabrication and applying the composition to a predetermined thickness; Spraying a solution containing calcium ions onto the applied sol-like composition to gel the surface; And removing the tray for mask fabrication on the mask film. This means that a chemically synthesized component must be contained in the mask pack to inject a composition in the form of a sol containing alginic acid. As a result, the freshness of the natural material can not be expected and there is a problem that the use of the chemical causes trouble to the skin .

Another prior art is Korean Patent Registration No. 10-0910120, a collagen derived from squid coat and a cosmetic mask pack containing the same, which relates to a method for extracting alkali insoluble collagen from a shell, which is a processing by-product of squid. Washing the squid outer skin with water, adding water and then pulverizing the squid outer skin; Centrifuging the pulverized material to obtain a precipitate; Adding NaOH to the precipitate and stirring; Centrifuging, neutralizing and lyophilizing to obtain collagen derived from squid skin; A step of dissolving and mixing squid skin collagen, a moisturizer, an antiseptic flavor, a cosmetic ingredient and a thickening agent in purified water; And filtering and adding the mixture to the mask sheet. However, in the case of this prior art, since collagen is obtained through the squid, it may be burdensome to use by the user, and there is a fear that the user may cause an allergic reaction to the skin due to squid.

Users who use mask packs are rapidly becoming popular for anti-aging (antioxidant) trends that pursue youth and beauty. As a result, anti-aging industry customers such as dermatology hospitals, cosmetics and beauty services are interested in beauty This is spreading to the general public. This indicates that anti-aging needs of young people in their 20s and 30s are evidenced by the recent research that preventive measures are more effective than aging revenues. In such a situation, there is a need to develop a technique for a cosmetic composition which can protect the skin by anti-aging substances and increase the anti-aging effect per unit weight.

Accordingly, an object of the present invention is to provide a mask pack cosmetic composition containing a pearl conchiolin extract for cosmetics which can secure the antioxidative effect while securing the safety, while overcoming the disadvantages of organic solvent extraction or high temperature and high pressure extraction, And a method for producing the composition.

The above object can be accomplished by a method of collecting freshwater pearls, Naturally drying the freshwater pearl at 20 to 40 DEG C without using a drier; The dried freshwater pearls are first and second pulverized, and the pulverized freshwater pearl powder is introduced into a stainless steel signboard of 1, 2, or 3 stages to form a cloth or net having a fine particle size, To obtain a fresh water pearl powder; Treating the fresh water pearl powder with an enzyme decomposition and processing into a gel state fresh water pearl gel; Obtaining a pearl extract composition extracted from the fresh water pearl gel through vacuum low temperature extraction and distillation extraction; Monoglycerin, diglycerin, triglycerin, propylene glycol, ethylene glycol, butylene glycol, dipropylene glycol, pentaerythritol, A wetting agent composed of a single or a mixture of two or more selected from alcohols such as glycerin, glycerin, glycerin, glycerin, glycerine, glycerin, , And the vacuum low-temperature extraction is carried out at a temperature of 50 to 65 ° C and a pressure of 0.06 Torr for 1 to 2 hours.

Here, the step of obtaining the freshwater pearl powder may include: firstly pulverizing the freshwater pearl through a cutting edge rotating at a speed of 3000 to 4000 rpm; And a second step of pulverizing the primary pulverized freshwater pearl through a cutting edge rotating at a speed of 4000 to 5000 rpm, and the enzyme decomposition is preferably performed by adding 5 wt% of calcium lactate.

Hereinafter, a method of manufacturing a cosmetic composition for a mask pack according to an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

As shown in FIG. 1, freshwater pearls are collected, sorted and cleaned (S1).

Generally, pearls are solid matter produced inside the pearl shells, and the main ingredients are calcium carbonate and other organic matter and moisture. Organic matter is mostly occupied by conchyolin, which is known as skeletal protein. Conkyrrhizin is the main ingredient of the remaining moss after dissolving the calcium salt in the shell of the shell with 5% diluted hydrochloric acid and is dissolved in the concentrated potassium hydroxide solution. It is a kind of protein different from the light protein contained in chitin, such as shrimp, crab and insect, but it is a component which is difficult to be decomposed by protein enzyme.

Pearl contains a variety of amino acids and trace elements that effectively stimulate the metabolism of cells in the epidermis and control the production of melanin on the face and inhibit the formation of skin troubles such as wrinkles, splashes, dark sore Have.

Pearls can be divided into seawater pearls, which are largely composed of seashells in seawater, and freshwater pearls, which do not have nuclei in seashells. Seaweed pearls contain a large amount of lead (Pb), which is harmful to human body, and have a problem in edible use. On the other hand, freshwater pearls have characteristics of being edible because they do not have a nucleus and nucleus.

Accordingly, in the present invention, cosmetic compositions for mask packs are prepared using pearls obtained from freshwater pearls which are free from nucleus and nucleus and can be edible, i.e., freshwater free from salt. After taking the pearls out of the fresh water, select the normal freshwater pearls and clean them thoroughly to avoid the presence of impurities. The object of the present invention is to obtain a high-quality composition by using ultrapure water freshwater pearls from which various impurities have been removed and minimizing impurities from other raw materials.

Freshwater pearls can be washed with distilled water, water, methanol, ethanol, etc., or by stirring with a hand or by removing all impurities that are poured on the freshwater pearl surface by the user It is desirable to obtain only pure fresh water pearls. In this case, washing is repeated 3 times or more, preferably 10 minutes or more per one time.

As the solvent used for washing, the above-mentioned solvent is most preferable, but in addition to this, any solvent that can be washed neatly without harming the components of the fresh water pearl can be used.

Freshwater pearls are dried naturally (S2).

Remove the washed freshwater pearls from the solvent and spread them evenly over the freshwater pearls to dry naturally at room temperature. At this time, it is preferable to use a tray having irregularities so that freshwater pearls are rolled and hit each other to damage the surface of freshwater pearls. However, the unevenness of the tray should not be so rough as to damage the surface of the freshwater pearl, and it is most preferable to use a tray having a soft touch bottom surface such as a sponge to protect the surface of the freshwater pearl.

It is preferable to naturally dry the freshwater pearl at 20 to 40 캜 at room temperature without drying it at high temperature. If the drying temperature is less than 20 ° C, it takes a lot of time to dry, which is not efficient in the manufacturing process. If the drying temperature exceeds 40 ° C, especially when it is dried at high temperature using an oven, However, the composition of freshwater pearls may change, making them unsuitable for use on skin. Therefore, the temperature for drying the fresh water pearl is most preferably 20 to 40 ° C.

The time for drying the freshwater pearls is preferably 24 hours, but it may be dried for more than two days if further drying is desired if necessary.

Freshwater pearls are first and second ground (S3).

After the drying step, the fresh water pearl in which the water is completely removed is subjected to the primary pulverization, that is, the primary pulverization and the second pulverization. A separate grinder should be used to crush relatively hard freshwater pearls.

The crusher is equipped with 2 to 3 cutting blades at the upper end rotating at 3000 to 4000 rpm and 20 to 30 cutting blades at the lower end to grind fresh water pearls through the cutting blades, Fresh water pearl powder is recovered through a recovery bin. Here, the cutting edge is selectively used with high speed steel, carbide or diamond tool, and the driving motor can be adjusted according to the degree of fracture.

In the crusher, a crushing tool for crushing freshwater pearls is installed in a second-order parallel structure, and the crushed freshwater pearls through the first crusher have a structure that becomes a smaller powder while passing through the secondary crushing tool.

The second fresh water pearling step is a step of pulverizing fresh water pearl powder pulverized in the first pearl pulverization step until fresh water pearl powder of a few millimeters (mm) is obtained, and the pulverizing tool is a pulverizing tool used in the first pearling step The same specifications apply.

The secondary pearl milling step comprises a crushing tool rotating at a rotation speed of 4000 to 5000 rpm and the pulverized freshwater pearl powder is provided with a cloth or cloth net having fine grain size in a stainless steel signboard of 1, And a grinding machine having a recovery box for recovering powder particles coming from a filtering net through a suction device using a compressor.

The freshwater pearl powder obtained through this step has a finely pulverized granule shape of less than 5 mm.

The freshwater pearl powder is enzymatically decomposed and processed into a gel state (S4).

The freshwater pearl powder obtained by finely crushing freshwater pearls is enzymatically decomposed. Degradation of enzymes is done by using enzymes as a way to hydrolyze proteins.

As a method for enzymatic degradation of freshwater pearl powder, it is most preferable to add calcium lactate to perform enzymatic degradation, whereby the freshwater pearl powder becomes a gel state. Here, 3 to 7%, more preferably 5%, of calcium lactate can be added. If the content of calcium lactate is less than 3%, the enzyme decomposition is not smooth. If the calcium lactate exceeds 7%, the content of calcium lactate is higher than that of freshwater pearl powder, .

In the past, folate was added to perform enzymatic decomposition. However, in this case, the user may feel a sense of rejection in using the mask pack due to the odor. Therefore, in the present invention, calcium lactate is used in consideration of sensory elements such as taste, aroma and the like and calcium content in the pearl component.

Such an enzyme decomposition method is one of the most preferred embodiments, and various enzymatic decomposition methods can be used in addition to this, and the enzyme decomposition method is not particularly limited.

It is preferable that the prepared freshwater pearl gel is dried to remove moisture by 80% or more. When the moisture is removed to less than 80% and more than 20% remains, the freshwater pearl gel is not a form suitable for the present invention because it is shaped like a liquid rather than a gel.

Thereby obtaining a pearl extract composition extracted from fresh water pearl gel (S5).

Vacuum low temperature extraction and distillation extraction are used to obtain pearl extract from fresh water pearl gel.

Generally, extraction is carried out by using an organic extraction solvent such as alcohol, methanol, ethanol, acetone, isopropanol, ether, carbon dioxide (CO ₂ ) And the extraction and concentration are carried out in the state of < RTI ID = 0.0 > However, such extraction using an organic extraction solvent has a problem that the safety of the extraction solvent can not be secured, and there is a problem that the nutrients inherent in each material are destroyed and lost in extraction at a high temperature and a high pressure. Accordingly, in order to avoid such a problem, the present invention provides cosmetic compositions for mask packs using vacuum low temperature extraction and distillation extraction.

Vacuum low temperature extraction is performed at 50 to 65 ° C, vacuum is performed at 0.06 Torr (0.079 mbar, 0.079 kPa), and vacuum low temperature extraction time is preferably 1 to 2 hours. If the temperature is lower than 50 ° C, it is not smoothly extracted. If the temperature is higher than 65 ° C, the active ingredient may be lost during the extraction. Therefore, it is preferable that the extraction is performed at 50 to 65 ° C, which can smoothly perform extraction, prevent the loss of active ingredient extraction, and maintain the nutritional integrity.

The maintenance of the atmospheric pressure in the vacuum state affects the temperature setting and the extraction time. Too short an excessively high degree of vacuum in order to shorten the extraction time may cause problems in the mixing of ultrapure water and pearl. That is, the pearl powder remains and only ultrapure water is distilled.

The extraction time may vary depending on the combination of the pearl powder. To explain this in more detail, ultrapure water and pearl powder are first introduced into the extraction tube and kept in a vacuum state. As the vacuum low temperature extractor, COSMOS 660 (specification: W1000 × L500 × H1800) of Kyongseo machine of Korea was used. For example, 2,000 cc of ultrapure water and 20 g of pearl powder are added to the extraction tube. Fig. 2 is a photograph showing the injection of ultrapure water and pearl powder into the extraction cylinder.

Ultrapure water and pearl powder are mixed at a weight ratio of 100: 1. The reason why the weight ratio is 100: 1 is based on the result of the experiment wherein the antioxidant effect is higher when the pearl powder is small.

Next, the extractor is sealed to keep the vacuum and prevent leakage of the active ingredient present in the water vapor generated during the extraction process. Figs. 3 and 4 show photographs in which the vacuum low-temperature extraction is performed while sealing the extractor.

The steam generated in the vacuum heating in the low temperature vacuum extraction is passed through the cooler, liquefied and collected in the distillation column. The distillate collected in the distillation column is circulated again to the extraction column to mix the final concentrated vacuum cold extract and the distillate.

The sulfation value is measured as higher than that of the distillate. Since the distillate is a clear and transparent liquid state, the cosmetic composition is used for items having a large liquid content such as skins and the extract is light yellow so that it is preferably used for creams Do. In the case of the present invention, in order to obtain the composition contained in the mask pack, it is preferable to use a composition in which the distillate and the extract are mixed at about 1: 1 weight ratio.

In addition, the method may further comprise impregnating the mask sheet for pack with the pearl extract composition.

When the pearl extract and the distillate are obtained, they are mixed at a weight ratio of about 1: 1 to form a pearl extract composition having an appropriate viscosity in the mask, and impregnated with the mask sheet. Here, the cosmetic composition is prepared so as to contain not only the pearl extract composition but also various components required for the mask pack, and impregnates the mask sheet.

Typically, the cosmetic composition may include a wetting agent. The wetting agent may be selected from the group consisting of monoglycerin, diglycerin, triglycerin, propylene glycol, ethylene glycol, butylene glycol, dipropylene glycol, And may be a single or a mixture of two or more selected from alcohols such as pentylene glycol, hexylene glycol, sorbitol and the like.

Glycerin may be added as a wetting agent. Glycerin imparts stretchability and elasticity to a mask pack, softens the skin after application of the skin, and facilitates the mask pack to deviate from the skin.

The wetting agent may also include dipropylene glycol. Dipropylene glycol prevents dust from being formed by sodium alginate powder when sodium alginate is dispersed in water and regulates the activity of water to impart antiseptic function. The dipropylene glycol is preferably contained in an amount of 0.10 to 0.1 part by weight based on the cosmetic composition. If the amount is less than 0.10 parts by weight, a hard film is formed on curing of the mask pack cosmetic composition, and the effect of skin softening is poor. If it exceeds 0.1 part by weight, the composition becomes unsuitable for a mask pack.
