Description

Cosmetic composition containing algae fiber {Cosmetic composition containing algae fabrics}

The present invention relates to a cosmetic composition containing the seaweed fiber as an active ingredient, and more particularly, by containing the seaweed fiber to improve skin moisturization, to adsorb harmful substances, to deliver the natural nutrients of seaweed to the skin and cosmetics It relates to a cosmetic composition capable of improving the viscosity and hardness of.

Wood, which is the most widely used natural fiber, is mainly composed of cellulose, hemicellulose, and lignin, and these components constitute the cell wall and the intercellular layer and are present in more than 90% of all species. Subcomponents include resins, essential oils, fats and oils, extracts such as tannins and flavonoids, and other inorganic substances. Among them, cellulose is present in the largest amount of organic compounds present in nature, and is the main component of the plant cell wall. In order to industrially use wood cellulose, it is used as wood sugar by making paper or hydrolyzing wood through processes such as cooking, bleaching and refining, and making and using cellulose derivatives through various chemical treatments. Doing.

Various operations are carried out to obtain fibers capable of producing pulp, which is mainly used as a raw material for paper, but it can be broadly classified into preparation, pulping and refining of fiber raw materials. In the process of processing a wood raw material in the state which is easy to pulp, there are operations, such as cutting, peeling, and sorting, and this is suitably performed according to the kind of raw material. The process of obtaining fibers from the raw material after the preparation process is called a pulping process and is the most important process in pulp production.

Fibers can be obtained by destroying the composite intercellular layer of wood, which is a pulp material, with a wood mill or by softening it with water vapor and then breaking it using physical force. The pulp obtained by simple mechanical treatment without chemical treatment is called mechanical pulp. Mechanical pulp has high yield and low production cost, but its high lignin content makes it unsuitable for high grade paper.

Treatment of the pulp feedstock with ligignin chemicals dissolves the complex intercellular layer and dissociates it into fibrous form. Pulp prepared in this way is called chemical pulp. In the preparation of chemical pulp, not only the lignin in the intercellular layer of the raw material but also most of the cell membrane lignin are removed, at the same time, many hemicelluloses are dissolved and some cellulose is also degraded. Chemical pulp has high quality, i.e., high purity of cellulose, but has a disadvantage of low yield and high production cost compared to mechanical pulp. Chemical pulp production methods include sulfurous acid method, soda method and sulfate method. The selection process is a process of washing and screening fibers obtained from the raw material after the pulping process to remove parts and contaminants that are not completely pulped, and then bleaching as necessary.

The above is the description about the general process of manufacturing pulp from wood raw materials. However, as the depletion of wood resources around the world has become severe, it has become a problem to produce paper stock pulp while protecting forests and the environment. As a solution to this problem, a technique for producing paper pulp from non-woody plant fibers mainly on first and second year plants has attracted attention.

In recent years, with the shortage of terrestrial resources, interest in marine resources, a new area, has increased, and the research and development of pulp using algae has begun. Algae have the advantage of having much more biomass than the wood, which is a land plant, because its structure is soft, the fibers are fine, and it is possible to grow without special management in a much larger space than the land. The growth rate is also faster than that of trees, no separate soil is needed for cultivation, the extraction of fiber is easy, the pulping process is simple, and the production facilities are inexpensive, and the development of pulp using algae has been conducted (Korea Patent Publication) 2005-46601 and 2007-40555).

Unlike land plants that are rooted on land and living in response to the ever-changing external environment, seaweeds that have high density and viscosity, and survive in the sea, which provide a relatively constant environment, show great differences in growth and organization. Terrestrial plants are slow to grow because they consume the energy they absorb, adapt to temperature, and multiply, whereas algae that survive by receiving nutrients directly from the surrounding seawater in a stable space show very rapid growth. In addition, the tissue is soft because there is no need to support itself, and its constituent fibers are also different from those of land plants.

Fibrous cells in algae are called endofibers, which occupy the majority of seaweed constituents, and are characterized by having a lumen used as a transport pathway for bioactive substances. These microcavities present in the fiber mean that algae fibers have a great development value as a natural porous material, and the lumen is activated as the bioactive substances existing inside the fiber pass through the fiberization process, thus making the cosmetic composition more suitable. It will be worth it.

1 is an endofiber micrograph of algae fibers. As shown in FIG. 1, the algae fibers are thin and uniform in tissue and have a significantly lower strength than wood. In general, the fiberization process using wood should be dissolved in a strong base such as sodium hydroxide and heated for more than 8 hours at high temperature and high pressure to dissociate the tissue, and to use various mineral bleach to maintain whiteness. However, algae fiber can obtain dissociated tissues only by heating for 2 hours at 100 ° C, and can produce white raw materials with bleaching using chlorine dioxide or hydrogen peroxide which can be used directly by the human body. If it is not treated, the material can be made of only edible materials without the addition of any chemicals, which is eco-friendly and produced by a simple process.

Seaweeds contain large amounts of water and are high in nutrients, making them prone to decay. It is known to use seaweed as a cosmetic composition by crushing it after freeze-drying, but agar is leaked, affecting the hardness and viscosity of the formulation, has a unique smell of seaweed, and is suitable as a material for cosmetics that is easily deodorized and needs long-term storage. Had not had a problem. In addition, the agar degreasing process, which can take advantage of the microporous structure, does not entail a disadvantage of not fully utilizing the advantages of seaweed fibers.

Therefore, the inventors of the present invention, while searching for a suitable method for applying seaweed to cosmetics, prevents discoloration and odor of seaweed and makes it possible to disperse seaweed fibers in a powder form that can be easily dispersed and utilized in the preparation of cosmetic formulations in the cosmetic composition. The present invention was completed by confirming that it can improve skin moisturization, adsorption ability to harmful substances, and viscosity and hardness of the formulation.

Accordingly, it is an object of the present invention to provide a cosmetic composition which improves skin moisturizing, adsorption capacity to harmful substances and viscosity and hardness of the formulation.

In order to achieve the above object, the present invention provides a cosmetic composition containing the seaweed fiber as an active ingredient.

The cosmetic composition according to the present invention contains the algae fibers as an active ingredient to improve skin moisturization, adsorption ability to harmful substances and viscosity and hardness of the formulation to improve the basic quality of the cosmetic formulation.

The present invention relates to a cosmetic composition containing seaweed fibers as an active ingredient.

Seaweed fibers used in the present invention, red algae, including wood starfish, stalk, kotoni, spino island, stone starfish, seaweed, sea vinegar, grass starfish, ox radish, buckwheat, stalk, thorn radish, silk grass, scabbard, stone and Jinuari; Green algae including greens, chlorella, jang-jang, half-moon, hearing and pollack; Or brown seaweed, including seaweed, kelp, mashed potatoes, shellfish, Ecklonia cava, gompi and antagonism and the like can be used, but is not limited thereto, and can be prepared from most seaweeds that maintain their shape in water.

The algae fibers used in the present invention can be prepared by a known method comprising the following steps:

a) removing the agar and pulping after boiling algae;

b) dehydrating the algae fiber by dispersing it in ethyl alcohol or alcohol;

c) centrifuging the mixed solution to remove alcohol; And

d) drying step.

For example, the seaweed fiber according to the present invention is immersed in the extraction solvent capable of dissolving the agar gel for a predetermined time to dissolve the agar gel with the extraction solvent, and then react the dissolved agar gel with the reaction solvent to fibrous After the conversion to the fiber, and the fiber is cured with a curing agent, it can be prepared by a method of pulping the cured fiber (see Korean Patent Publication No. 2005-46601).

Alternatively, the algae fibers used in the present invention are immersed in an acidic solution such as acetic acid, then washed with water and dehydrated, and the dehydrated algae are immersed in an extraction solvent such as water for a predetermined time to extract the agar gel. Next, the extracted residue may be bleached in multiple stages and collected to prepare algae fibers. Seaweed fibers do not require toxic chemicals because they do not require a separate deliquescent process, and can maintain whiteness even without mineral bleach (see Korean Patent Publication No. 2007-40555).

The finished algae fiber is composed mainly of fructose and cellulose, and is not dissolved in water or melted by heat, and its thickness is 1 to 10 µm and its length is several tens to thousands of µm. The particle size varies depending on the type of seaweed used, but filters and grinding can be used to obtain fibers of the desired size.

The algae fiber may contain 1300% water relative to the original weight, and 52.4% of the water contained in the seaweed may be used as an excellent natural moisturizing material until 9 hours have elapsed. In the heavy metal impregnation experiment with cadmium, it has a high heavy metal impregnation ability by adsorbing 63.1% of heavy metal.

The cosmetic composition according to the present invention may contain the seaweed fibers in an amount of 0.01 to 20% by weight based on the total weight of the composition. If the content of the seaweed fiber is less than 0.01% by weight has little effect on the properties of the finished formulation, when it exceeds 20% by weight, the viscosity and hardness are excessively increased, the fluidity is lost, and the fiber is largely entangled and lumped There is a problem that can not be used as a cosmetic.

The formulation of the cosmetic composition containing the seaweed fiber according to the present invention is not particularly limited, and may be, for example, an organic solution or an aqueous solution in which the active ingredient is dissolved, or a polymer particle or lipid particle solution supporting the active ingredient. Or any cosmetics such as softener, nourishing cream, massage cream, nourishing cream, lotion, ointment, gel, lipstick, mascara, cleansing oil, cleansing cream, spray, powder, foundation, eyeshadow, foam cleanser or shampoo Can be used in cleaning product formulations.

In addition, in the cosmetic composition of each formulation, other components other than the seaweed fibers of the present invention described above can be appropriately selected and blended by those skilled in the art according to the formulation or purpose of use of other cosmetics, in this case can be applied simultaneously with other raw materials Synergistic effects may occur.

The seaweed fiber cosmetic composition according to the present invention is effective in improving product quality by providing moisture and swelling, adsorption to harmful substances and marine nutrients as natural porous materials.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the following examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto.

Reference Example 1 Seaweed Fiber Preparation

The shellfish collected from the sea of East Sea of Korea was washed with clear water to remove the attached shellfish or foreign matters first, and steamed for 2 hours using steam. Thereafter, acetic acid was mixed with 5%, mixed with 100 parts by weight of water to remove agar, and the remaining fiber was used as a raw material of seaweed fiber. The agar was extracted three times with ethyl alcohol at 60 ° C. in order to completely remove the agar. The removed agar can be utilized for its intended purpose. Pegasus International was responsible for the manufacture of algae fibers, and the original process of the patent is to chlorine dioxide, which is used as a disinfectant for tap water or swimming pools, and then bleached with hydrogen peroxide. Therefore, if you want to use the texture of the seaweed may not proceed with the bleaching process. Bleaching of the material used chlorine dioxide and hydrogen peroxide water applicable to the human body (see Korean Patent Publication No. 2007-40555).

The obtained fiber is subjected to a process of removing the remaining shells, dirt, dust, etc. through centrifugation, and dehydrated using ethyl alcohol or spirits after dehydration. If the dehydration process using ethyl alcohol is not carried out, agglomeration of fibers occurs in the drying process, which leads to difficulty in dispersion. The dehydrated fiber was prepared by removing the alcohol component by centrifugation and the like, followed by vacuum drying at 60 ° C. and then pulverizing with a blender.
