Abstract
The present invention relates to a mask pack product and a method for manufacturing the same, which can improve water retention and transparency upon liquid absorption by substituting carboxymethyl groups for hydroxyl groups of a cellulose nonwoven fabric to adjust the degree of substitution of the carboxymethyl groups to 0.05 to 0.3.
Description
Technical Field
The present invention relates to a mask pack product using a low-substituted carboxymethyl cellulose non-woven fabric, and more particularly, to a mask pack product using a low-substituted carboxymethyl cellulose non-woven fabric and a method for manufacturing the same, in which the substitution degree of carboxymethyl groups of a cellulose non-woven fabric is adjusted to 0.05 to 0.3, thereby improving water retentivity and transparency.
Background
The mask patch is used for being stuck on the surface of skin and being taken out after a certain time, so that the skin can absorb moisture, oil and nutrition contained in the mask patch.
Conventional face masks are produced by using cellulose fiber materials, polypropylene, polyethylene terephthalate, and other materials alone or by mixing these materials.
Among them, a mask pack made of a synthetic material such as polypropylene or polyethylene terephthalate is difficult to effectively deliver functional active ingredients such as moisture retention, soothing, and elasticity to the skin because of its low application property to the skin and low water retention property.
Cellulose fiber is an environmentally friendly polymer that forms fibers by aggregation of a large number of cellulose unit molecules. The cellulose fibers include crystalline regions and amorphous regions that swell when immersed in water due to liquid penetration into the amorphous regions. Because of such characteristics, a mask pack using cellulose fibers is known to have excellent application properties to the skin and water retention properties.
However, with the development of expensive materials such as hydrogels having water retention and transparency, cellulose fibers have limitations in satisfying the water retention and transparency required by consumers. However, there is still an increasing demand for cellulose fibres, since they are natural materials and have a good cost-effective performance.
Therefore, there is a need to develop a mask patch which not only satisfies both water retentivity and transparency, but also has excellent cost performance.
Disclosure of Invention
[ problem to be solved ]
The invention aims to provide a mask patch with excellent water retention and transparency. In addition, the present invention aims to provide a method for manufacturing a mask pack product in which the concentration of a carboxymethylating agent is adjusted so that the degree of substitution of carboxymethyl groups is adjusted to 0.05 to 0.3. The objects of the present invention are not limited to the above objects, and other objects of the present invention not mentioned and advantages thereof will be understood by the following description and more clearly understood by the embodiments of the present invention.

The same reference signs in the drawings refer to the same or like elements.

Next, a mask pack product using a low-substituted carboxymethyl cellulose nonwoven fabric and a method for manufacturing the same according to an embodiment of the present invention will be described.
The invention can prepare the facial mask pasting product with the carboxymethyl substitution degree of 0.05 to 0.3 of the cellulose non-woven fabric by adjusting the reaction liquid for dissolving the carboxymethylating agent in water and the concentration thereof. The low-substituted carboxymethyl cellulose of the present invention refers to a cellulose having a degree of substitution of carboxymethyl groups of 0.05 to 0.3.
Fig. 1 is a flowchart of a method for manufacturing a mask pack product using a low-substituted carboxymethyl cellulose non-woven fabric according to the present invention.
Referring to fig. 1, the method for manufacturing a mask pack product of the present invention includes the steps of: dipping the cellulose non-woven fabric in an alkaline solution for pretreatment S110; performing extrusion S120; preparing a reaction solution S130 by dissolving a carboxymethylating agent in water; adding the extruded cellulose non-woven fabric into the reaction solution to carry out substitution reaction S140; and drying after extrusion S150.
Step S110 of immersing cellulose nonwoven fabric in alkaline solution for pretreatment
This step is a process of immersing the cellulose non-woven fabric in an alkaline solution and aging it so that the reaction process can be smoothly performed. If the pretreatment process is insufficient, the substitution reaction does not occur, and thus the pretreatment process is particularly important. The pretreatment process is a process that needs to be carefully adjusted because the characteristics of the cloth may vary depending on the temperature and time of the pretreatment process.
The cellulose nonwoven fabric used in the present invention means a natural cellulose fiber having a repeating unit of 200 to 5000. If the repeating unit is less than 200, it is difficult to maintain the sheet shape due to the decrease in fiber strength. On the other hand, if the repeating unit is more than 5000, the dissociation of the hydroxyl group by the base is weakened, and it is difficult to adjust the degree of substitution.
The concentration of the alkaline solution used for impregnating the cellulose non-woven fabric cloth is 15 to 40%. The alkaline solution may be mixed with one or more strong alkali chemicals such as sodium hydroxide (NaOH), potassium hydroxide (KOH), ammonia (NH4OH), or trimethylammonium hydroxide (Trimethyl ammonium hydroxide). Among them, sodium hydroxide is preferably used as the alkaline solution.
If the concentration of the alkaline solution is less than 15%, it is difficult to obtain a desired degree of substitution due to low alkalinity. On the contrary, if it is more than 40%, the degree of reaction with the carboxymethyl solution increases, so that the degree of substitution becomes too high, or more side reactions occur, thereby possibly causing a decrease in the physical properties of the cloth.
The cellulose non-woven fabric needs to be soaked in an alkaline solution and then subjected to a curing process. Ripening is a process for the dissociation of hydrogen bonds of cellulose molecules and is usually carried out at a temperature of 20 to 70 ℃. If the temperature is below 20 ℃, a long time is required to achieve a suitable maturation. If it exceeds 70 ℃, a large amount of excess reaction occurs, resulting in embrittlement of the fibers. In addition, the aging time needs to be adjusted. Since the aging time varies depending on the mixing ratio, the impregnation time, the aging temperature, and the equipment characteristics, it is preferable to optimize by measuring the degree of substitution of the final nonwoven fabric.
Step S120 of performing extrusion
The cured cellulosic nonwoven is then pressed to its correct extent by passing it through two rolls under controlled pressure.
The pressing is a factor that determines the amount of alkaline solution remaining in the nonwoven fabric, because only a part of the alkaline solution used for the aging is retained to satisfy the amount required for the cellulose nonwoven fabric and the rest is removed. The pressing is to determine the pick-up rate of the cloth by adjusting the pressure between the rollers, preferably, the pick-up rate is 200 to 500%. The pickup rate (%) represents a ratio of the amount of the alkaline solution remaining in the cellulose nonwoven fabric after the impregnation divided by the dry weight of the cellulose nonwoven fabric.
That is, the pickup rate (%) was { (wet weight-dry weight)/dry weight } × 100.
If the pick-up ratio is less than 200%, the hydrogen bond dissociation of the cellulose molecules is insufficient, and it may be difficult to adjust the degree of substitution. On the contrary, if the pick-up rate is more than 500%, the hydrogen bond dissociation of the cellulose molecule is excessive and the degree of substitution may be excessively high.
Therefore, it is important to achieve a pickup rate of the cellulose nonwoven fabric with respect to the alkali solution of 200 to 500% by appropriately adjusting the pressing.
Step S130 of preparing a reaction solution by dissolving a carboxymethylating agent in water
After aging, a reaction solution was prepared by dissolving a carboxymethylating agent in water.
The carboxymethylating agent is a drug for substituting carboxymethyl in the cellulose nonwoven fabric, and a halogenated acetic acid such as monochloroacetic acid, monobromoacetic acid, monoiodoacetic acid, etc. or a neutralizing agent thereof may be used.
The carboxymethylating agent is the most important factor determining the degree of substitution, and preferably, 20 to 60% by weight of the carboxymethylating agent is dissolved in 40 to 80% by weight of water to prepare a reaction solution. If the amount of the reaction solution added is less than 20% by weight, there is a problem that the degree of substitution decreases, while if it exceeds 60% by weight, excessive substitution may occur.
In addition, in order to prevent the side reaction, distilled water, ion-exchanged water, or RO water (water filtered by reverse osmosis) from which metal components causing the side reaction are removed may be used as the water. If the metal content in water exceeds 50ppm, side reactions may occur. The metal may be calcium, magnesium, iron, copper, etc.
Step S140 of adding the extruded cellulose nonwoven fabric to the reaction solution to perform substitution reaction
The extruded cellulose nonwoven fabric was put into the prepared reaction solution, re-impregnated, and heat-treated to perform substitution reaction.
At this time, preferably, the cellulose nonwoven fabric that has been extruded is: the weight ratio of the reaction liquid is 1: 2 to 1: 8, more preferably, in a ratio of 1: 4 to 1: 6 and mixing. If the content of the reaction liquid is less than 2 times that of the extruded cellulose nonwoven fabric, the substitution reaction rate will be low due to the insufficient content of the reaction liquid. On the other hand, if the content of the reaction solution is more than 8 times, there is a problem that the side reaction rate increases.
The substitution reaction can be induced by heat treatment at 70 to 150 c, and if it is lower than 70 c, the degree of substitution is low, and if it is higher than 150 c, fiber embrittlement is caused, resulting in tearing of the fabric. The substitution reaction can be carried out within 5 minutes, and if it exceeds 5 minutes, an excessive reaction may occur.
The substitution reaction is to substitute an anionic group such as carboxymethyl group for a hydroxyl group (-OH) at the terminal of the dehydrated cellulose nonwoven fabric. The carboxymethyl group may be represented by-CH 2COO-Na +.
The cellulose nonwoven fabric having undergone the substitution step has anionic water solubility, high water retentivity (moisture-protecting/retaining property), and high transparency.
After the substitution reaction is completed, in order to remove the unreacted cellulose nonwoven fabric derivative, washing with water or a mixed solution of water and an ethanol-based organic solvent may be performed 2 to 3 times. At this time, in order to adjust the pH of the cellulose nonwoven fabric subjected to the substitution step, it is preferable to neutralize the final pH of the fabric by adding an acidic drug such as sulfuric acid, phosphoric acid, hydrochloric acid, formic acid, or acetic acid.
Step S150 of drying after extrusion
Then, the cellulose nonwoven fabric subjected to the substitution step is extruded and dried to manufacture a mask product. Preferably, the manufactured mask patch product is in a non-woven form.
Specifically, pressing is performed after the washing is finished, and drying is performed at 100 to 150 ℃. If the drying temperature is less than 100 ℃, the mask patch product may not be sufficiently dried. In contrast, if the drying temperature exceeds 150 ℃, the mask patch product may be yellowed as the temperature increases. In addition, the extrusion may be performed at 25 ± 10 ℃, preferably, at 25 ± 5 ℃, by applying pressure.
The dried mask pack product is impregnated in a solution containing one or more functional skin-improving components selected from the group consisting of moisture-retaining, soothing, elasticity-improving, wrinkle-improving and whitening components, thereby having any one or more functional effects of moisture-retaining, soothing, elasticity-improving, wrinkle-improving and whitening.
Therefore, in the present invention, by using a reaction liquid in which a carboxymethylating agent is dissolved in water and by adjusting the concentration of the reaction liquid, a mask patch product including a low-substituted carboxymethyl cellulose nonwoven fabric having a carboxymethyl substitution degree of 0.05 to 0.3 can be manufactured. The mask paste product using the low-substituted carboxymethyl cellulose non-woven fabric has high water retention and transparency, and therefore, can be used as a product with excellent cost performance.
The mask pack product manufactured according to the manufacturing method of the present invention includes a cellulose nonwoven fabric having an end substituted with a carboxymethyl group. The cellulose nonwoven fabric is characterized in that the degree of substitution of carboxymethyl groups is 0.05 to 0.3.
The mask pack product may contain one or more skin function-improving components having moisture-retaining, soothing, elasticity-improving, wrinkle-improving, and whitening effects by being impregnated in an essence or solution having a skin function-improving effect.
Therefore, the mask pack product of the present invention is a product that can come into contact with the skin for cosmetic purposes, and thus can provide an effect of improving the skin.
