Description

Korean paper powder and the method for preparing cosmetics

The present invention relates to a cosmetic hanji powder and a method for manufacturing the same, and more particularly, to a cosmetic paper powder having excellent breathability prepared by separating and purifying the pulp from powdered mulberry, which is a raw material of hanji, and a manufacturing method thereof will be.

The main raw material of Hanji is paper mulberry. Since the Three Kingdoms era, the mulberry bark has been used mainly for Korean paper, banknotes, Korean paper, and wind papers. The wood part has been used for composting after crushing. The fiber collected from the mulberry tree was rarely used for textile products because of its relatively weak fiber and short fiber length among the homogeneous bast fibers. It was limited to the manufacture of papers and traditionally mainly used for the manufacture of Korean paper. Has been.

Traditional Korean paper manufacturing method is as follows.

Hanji has been manufactured by the original papermaking method. Traditional Korean paper manufacturing method is largely divided into eight processes. In other words, the process can be divided into the following steps: making, boiling, washing, sun-tapping, paper-making, draining, drying, and trimming.

The bark of the bark consists of the bark (black skin) and the inner skin (white skin). First, it is steamed to remove the black skin, that is, to make the bark peel off well. Peeled bark of this dried mulberry tree becomes white skin. Soak well-dried white skin in water for a day or two and soak it. Cut the white skin to the appropriate size, add lye and boil for 4-5 hours. The lye is then washed from the boiled stock and bleached by drying in sunlight. The tea is picked by hand from the finished raw material after washing and bleaching, and then the white skin is placed on the stone and beated with a bat for 40 to 60 minutes to perform the beating process. During this process, the fibers are released, and then the mulberry sap is added to the fully loosened raw material and stir again to keep the fibers in a constant concentration throughout. Next, we make paper by shaking the front, back and left sides by dipping the feet into paper containers filled with paper rolls. Traditional papermaking method of Hanji is unilateral knitting, but recently, a modified twinning method is used. The foot on which the wetland is placed is transferred from the foot to each other, and the wetland is piled up by pressing a paddle and pressed to remove moisture. Trimming is one of the finishing methods of Hanji. First, apply a thin rice paste on the surface of a thinly dried paper with a red sesame or treadmill-shaped infiltrator, layer it tens of times and tap it hundreds of times to make the paper dense and smooth, and increase the strength and glossiness to obtain the final hanji. In recent years, the manufacturing process of Korean paper has been improved by introducing some techniques for producing paper. In other words, when boiling white skin, use chemicals such as sodium carbonate, sodium hydroxide and sodium hydroxide instead of lye. However, when boiled with strong alkaline chemicals such as sodium hydroxide, the fiber itself is damaged and loses its gloss, not only decreases its strength and yield, but also causes a lot of damage to the lipids of Hanji. In addition, beating process also performs mechanical knife beater to increase productivity. The dissociation process is also performed using a screw, and after dissociation, polyacrylamide or polyethylene oxide, which is a polymer, is used instead of the mulberry. In the drying method after papermaking, the iron plate heated by steam is used to spread the paper on the drying plate and to dry and trim the process.

During the manufacturing process of Hanji, when the dried mulberry fiber pulp (wet state), which is made of pulp by beating the white bark, is hardened as the fiber and fibers are tangled, the sea island (fiber and fiber separated) is almost This becomes impossible because of the characteristics of bast fibers, such as pectin and lignin, which bind fibers and fibers, to bind fibers and make them hard during drying. This feature works well for paper making, but it is the biggest obstacle to use for other textile products. Therefore, there are currently few applications using the bask fiber of Korean paper. Recently, as part of broadening the applicability of bast fiber, Korean Laid-Open Patent Publication No. 2007-0041808 discloses a mulberry fabric using a mulberry fiber forming a bark of bark and its manufacturing method. In 2003-0072966, this known technique is characterized by the removal of binding substances such as lignin in order to prevent aggregation of the bast fibers mentioned above. Through this technique, the bast fibers obtained through the pulp can be obtained in the state of the fiber, not agglomerated state, and it is revealed that the Hanji fiber can be manufactured through the fiber manufacturing process, which is a known method after the fiber state is obtained.

Accordingly, the present inventors conducted research to expand the applicability while making use of the characteristics of Hanji, and by applying the mulberry fibers as a raw material for the manufacture of Hanji, effectively removing the fiber binding agents such as pectin and lignin contained in pulp of the mulberry fiber The present invention was completed by discovering that it is possible to manufacture a cosmetic Hanji powder having the various properties of the Doc fiber by making it a cosmetic powder and utilizing the characteristics of the Korean paper by the structure as a fiber.

Accordingly, it is an object of the present invention to provide a cosmetic hanji powder excellent in the usability and breathability, and a manufacturing method thereof.

In order to achieve the above object, the present invention provides a cosmetic hanji powder excellent in breathability by manufacturing and separating the fibrous fibers and a manufacturing method thereof.

The cosmetic Hanji powder according to the present invention has excellent breathability, which is a characteristic of Korean paper, and when it is blended into a basic cosmetic lotion such as a lotion or cream, it can secure moisture breathability and impart moisture protection to the skin. .

In general, it is known that Korean paper made of paper mulberry can pass wind and light and control humidity. This is because there are invisible holes on the micro surface of Hanji so it can naturally control the temperature and humidity inside the ventilation. The present invention provides a cosmetic Hanji powder and a method for manufacturing the cosmetic prepared from the paper mulberry fiber exhibiting the characteristics of such hanji.

In the present invention 1) pulping the mulberry; And 2) powdering the pulp of mulberry fiber to provide a method for producing a cosmetic hanji powder comprising.

When subdividing the manufacturing method of the hanji powder for the cosmetic,

1) treating the mulberry bark with an alkaline solution to remove the husks (black skin);

2) bleaching the prepared mulberry bark with a bleach to prepare a white skin;

3) pulping the mulberry fibers by adding an alkali agent to the white skin prepared in step 2);

4) washing and drying the mulberry bast fiber pulped in the step 3); And

5) powdering the dried mulberry bast fiber by hydrolysis;

It may include.

The alkaline solution used in step 1) includes sodium hydroxide, ammonium hydroxide and copper hydroxide aqueous solution, wherein the alkaline solution is a weak alkali concentration and smooth mixing to remove pectin and lignin present in the mulberry. It is used as a weight ratio of the bark and about alkali to the weight of the mulberry bark 1: 1: 5 to 1:50, preferably deposited at a weight ratio of 1:10 to 70 ~ 90 ℃, preferably 80 ℃ 4 Stir with heating for ˜5 hours. If the concentration of the weak alkali is too low compared to the bark bark, it is difficult to remove sufficient impurities, and if the concentration of the weak alkali is higher than necessary, the binding strength of the fiber occurs. Through this process, it is possible to prepare an epidermis from which pectin, lignin, and the like, which are binding materials of the mulberry fiber tissue, are removed.

In step 2), the prepared mulberry bark is prepared by adding one or more bleaches selected from the group consisting of calcium hypochlorite, sodium hypochlorite and sodium chlorite in a weight ratio of 1: 8 to 1:20 relative to the mulberry bark.

In the step 3), 10 wt% alkali hydroxide, such as sodium hydroxide, is added in a ratio of 1: 6 to 1:20 to the weight of the mulberry as a method or a chemical method by a beating machine, which is a mechanical method, to finely fiber the white skin. It is possible to pulp the mulberry fibers by completely removing pectin and lignin, which are fiber binding substances of bast fibers. In the present invention, the final pulp treatment was carried out using a mechanical method rather than a chemical method. This is because the frequent use of aqueous sodium hydroxide solution may shorten the molecular chain of the desired cellulose.

In step 4), the fiber binding material is removed, that is, washed with bask fibers containing only pure cellulose fibers, and then dried to about 80 ~ 90 ℃ in a convection dryer.

Lastly, the bast fiber purified from the step 5), ie, mulberry pulp, is a form in which hemicellulose, lignin, etc., which are present, are removed. More specifically, the purified paper mulberry pulp is present in a high content of alpha cellulose, there is no lignin and a relatively low content of hemicellulose. Since then, the bast fiber is maintained for about 48 hours at about 50 ~ 60 ℃ and undergoes the hydrolysis step in a conventional method well known in the art to finally obtain a microcrystalline cellulose in the colloidal state, which is commonly performed in the art It can be dried by a method such as spray drying to produce a cosmetic Hanji powder according to the present invention.

Hanji powder for cosmetics according to the present invention prepared by the above method is characterized by excellent breathability and excellent moisture permeability, lotion, cream, essence, pack, foundation, pact, twin as a basic cosmetic or makeup cosmetics It can be used for products such as cakes, face powders and shadows.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, these examples are intended to illustrate the present invention, it is obvious to those skilled in the art that the scope of the present invention is not limited to these examples.

Example 1 Preparation of Paper mulberry powder

1) Pulping of Paper mulberry

A 10% (w / v) aqueous sodium hydroxide solution was deposited at a ratio of 1:10 relative to the bark and stirred at 80 ° C. for 4 hours. Through this process, the epidermis from which pectin, lignin, and the like, which is a binding material of the mulberry fiber tissue was removed, was prepared. For whitening of the epidermis, 0.5N calcium hypochlorite aqueous solution was stirred at room temperature for 4 hours at a ratio of 1:10 to the weight of the epidermis, followed by washing with sufficient water to prepare the epidermis.

The treated white mulberry was pulp by the beating process. This process was performed using beater in consideration of productivity rather than the traditional method. As the treated epithelium passes through the beater, fibrillation occurs due to the impact from the blade of the beater.

2) Powder Preparation from Paper Mulberry Pulp

The pulp of the mulberry fiber was put in a ratio of 1: 5 (w / v) in an aqueous solution of 4N hydrochloric acid, and then stirred using a low speed stirrer. Maintained at about 50 ° C. for 48 hours, the hydrolysis proceeded and the residue was washed with water and neutralized with ammonia. After washing again with sufficient water to remove the salt, and dried in a convection dryer at 80 ℃, the distilled water was added to the residue again to prepare a dispersion of hydrolyzed mulberry fibers to a concentration of about 20% (w / v). Spraying the dispersion of the mulberry fibers to obtain a powder of the mulberry fibers. The recovered powder was ground with an air jet mill and subjected to a screening process to obtain fine powdered paper mulberry powder.

Test Example 1 Autonomous Humidity Effect of Hanji Powder

First, a constant temperature and humidity bath was installed to measure the movement of moisture. Inside the cup was installed a cup that can pass moisture, a constant amount in the open portion of the top of the cup, about 0.5 ~ 2g test sample, that is, the mulberry Hanji powder prepared in Example 1 and the commercially available cellulose powder (manufacturer: Nippon Paper Chemical Co. Ltd) was loaded. Samples 1 and 2 are samples according to the above invention. We experimented with 2 lots for reproducibility, and similarly with the same 2 lots of regular cellulose powder. Common cellulose powder is a powder prepared using cellulose obtained from ordinary wood. It measured by setting the case where indoor humidity is higher than outdoor. The internal humidity of the cup was maintained at 75% relative humidity by saturated potassium chloride aqueous solution, and the humidity of the constant temperature and humidity bath was maintained at 25% relative humidity by saturated magnesium chloride aqueous solution. When the indoor humidity is higher than the outdoor humidity and the water vapor flows from the indoor to the outdoor, the amount of indoor water vapor escaping from the outdoor through the paper mulberry powder, that is, the moisture permeability and the moisture absorbed by the paper mulberry powder were measured. . When the movement of water vapor occurs, the reason for measuring the moisture permeability and moisture absorption in the paper mulberry Hanji powder present at the interface is because the outdoor space is infinite because it can be assumed that the humidity does not occur even if the indoor water vapor is added.

The inside of the cup may be defined as the internal system, and the constant temperature and humidity chamber outside the cup may be defined as the external system. Since the amount of water vapor in the internal system is larger than that of the external system, the steam is moved from the internal system to the external system by the difference of partial vapor pressure between the two systems. Water vapor then passes through the boundary between the inner and outer systems. In other words, it passes through the paper mulberry powder existing on the interface. At this time, the moisture permeation rate of the water vapor passing through the interface was measured by using an electronic balance at an interval of 1 hour from about 2 hours after the stable state of the internal and external systems was reached. 1 is shown.

Comparison of the sample's moisture permeability sample F [g / h] F'g / m2 h] R [m2 h mmHg / g] #One 0.171 39.76 0.265 #2 0.181 42.09 0.250 # 3 0.123 28.6 0.3680 #4 0.121 29.13 0.3740

[Samples 1, 2: Paper mulberry Hanji powder, Samples 3, 4: Cellulose powder (manufacturer: Nippon Paper Chemical Co.Ltd)]

F is a time average water vapor transmission rate which permeate | transmitted the sample of 0.0043m <2> after 2 hours of experiment start to which water vapor transmission rate becomes constant. F 'is converted into moisture per unit area. The moisture-permeable resistance R of the Hanji powder was calculated by Equation 1 using the moisture-permeable amount measured.

R = (P1-P2) * A / F

(A: moisture vapor transmission area, P1-P2: partial pressure difference)

As a result of the measurement, the moisture permeability of sample 1 and sample 2 was similar, and sample 1,2 showed about 40% enhanced moisture permeability compared to samples 3 and 4. As can be seen from the above results, the powder applied with the material of the traditional Korean paper mulberry shows excellent moisture permeability compared to other types of powder. This reason appears to be due to the complex, fine fibrous texture peculiar to the mulberry.
