Description

Hydrogel Alginate Non-woven mask pack [0002]

More particularly, the present invention relates to an alginate nonwoven mask pack produced by blending calcium alginate polymer fibers and a different kind of fibers in the form of a sheet, wherein the insoluble calcium alginate polymer in the calcium alginate polymer fiber is water- Wherein the hydrogel alginate nonwoven fabric is modified with hydrogel alginate.

In general, the cosmetic mask pack is made by adding water or lotion to a sheet such as a nonwoven fabric, or adding a cosmetic solution such as a natural or synthetic substance known to have a function. Such a cosmetic mask pack is a functional cosmetic product which is attached to the face and supplies the cosmetic ingredient contained in the mask pack to the skin, thereby moisturizing the skin and removing the waste matter of the keratin and pore to restore the skin physiological function It is a kind.

In such a mask pack, there are various kinds of sheets to which a cosmetic ingredient is applied, and among them, a nonwoven fabric type which can be made thin is widely used. The nonwoven mask pack is manufactured by cutting a thin nonwoven fabric into a face shape and immersing the cosmetic ingredient on one face thereof, which is advantageous in that it is inexpensive and easy to use.

However, even if the nonwoven mask pack is fixed to the skin, the nonwoven mask pack is not firmly adhered to a desired site, and a part of the pack is excited at the bending portion, so that the cosmetic ingredient of the mask pack is not effectively transferred to the skin. In addition, the synthetic polymer is often added to the nonwoven fabric in accordance with the manufacturing process, and when the cosmetic liquid is added, the resultant fiber becomes stiff, and the feeling of use is poor and the skin affinity is low. In addition, in the case of a formulation in which the nonwoven fabric is soaked in an additive such as a cosmetic liquid to induce continuous absorption of the cosmetic liquid, the skin adhesion is poor, and since too high a cosmetic ingredient comes into contact with the skin at an early stage, disadvantage And 10 to 15 minutes, the moisture is evaporated and dried, and the mask pack falls off the face.

In order to overcome the drawbacks of such a nonwoven mask pack, research and development on a hydrogel mask pack have been actively conducted. The hydrogel is a material having a three-dimensional hydrophilic polymer network structure using purified water as a dispersion medium. The hydrogel is capable of absorbing a large amount of water, and has the same flexibility as a natural tissue. The hydrogel has elasticity, skin adhesion, Is used as a mask pack substrate improved in moisturizing, nutritional supply or exfoliation effect.

However, when a mask pack is manufactured using only the hydrogel itself, the shape of the mask pack may be difficult to maintain due to its low mechanical strength. In order to maintain the shape of the mask pack, a synthetic resin, a nonwoven fabric, ), And the like. However, in this case, since the gel-like hydrogel may elute the chemical components of the synthetic resin, it is necessary to examine from the standpoint of biocompatibility and stability, as well as inconvenience due to the use of the support, insufficient cosmetic ingredients and relatively high There are disadvantages such as price.

In order to improve the disadvantages of the nonwoven mask pack and the hydrogel mask pack as described above, a hydrogel mask pack, a method for producing the same, and a composition used for the production thereof (hereinafter referred to as Patent Document 1 Discloses a hydrogel nonwoven fabric, a method for producing the nonwoven fabric, and a mask pack (hereinafter referred to as "Patent Document 2") using the same, which are disclosed in Japanese Patent Application Laid-Open No. 10-1296105.

However, in Patent Document 1, a hydrogel mask pack is manufactured by gelating a composition for a hydrogel mask pack. Rather, due to excessive adhesive force of the product itself, a phenomenon of aggregation occurs in the mask pack product itself, There is an inconvenience. Patent Document 2 discloses that a hydrogel is impregnated using a nonwoven fabric as a mask pack support, and there is a possibility that the gel-like hydrogel still elutes the chemical components of the synthetic resin, thereby causing skin trouble due to skin irritation There was a problem that could be.

Hereinafter, the present invention will be described in detail.

An alginate nonwoven mask pack produced by mixing calcium alginate polymer fibers and different types of fibers by using calcium alginate polymer fibers made of alginate as a raw material, wherein the calcium alginate polymer fibers are mixed with calcium Characterized in that the alginate polymer is modified with water-soluble hydrogel alginate.

The alginate of the calcium alginate polymer fiber is a kind of seaweed polysaccharide which constitutes a cell membrane and intercellular material of brown algae which is one of the marine organisms and is often called alginic acid. It is a block of malonic acid (M) unit, a block of glutaric acid And the block of MG unit in the middle is a linear copolymer composed of 1,4-glycoside.

[Reference drawing 1]

Structure of Alginate

These alginates are used in the form of sodium alginate, which is water-soluble rather than alginic acid itself, which is usually insoluble in water, because the alginic acid has a carboxyl group (-COOH) of uronic acid in the molecule. When the calcium chloride solution is spun in a coagulating bath, . Particularly, alginic acid has functions and effects such as water retention, stickiness, lubricity, gelation and emulsification stability, physiological activity, and is not toxic to human body, easy to process, Is widely used.

In general, the calcium alginate polymer fiber of the alginate nonwoven mask pack forms calcium insoluble calcium alginate which is insoluble in water through strong ionic bonding instead of hydrogen in the carboxyl group of the alginate. If the mask pack is manufactured by blending, the skin adhesion feeling and feel are deteriorated, and the cosmetic ingredient of the essence liquid is not effectively transferred to the facial skin.

Therefore, it is necessary to convert the calcium alginate polymer fibers of the nonwoven mask pack into water-soluble alginate fibers so as to improve the adhesion feeling, feel and transparency of the mask pack. This is achieved by modifying the insoluble calcium alginate polymer in the calcium alginate polymer fibers with water-soluble hydrogel alginate So that the calcium alginate polymer fiber has a water-soluble property.

In the present invention, the modification is carried out by replacing the calcium ion of the insoluble calcium alginate polymer with a metal salt.

The metal salt may be any one selected from the group consisting of sodium chloride, sodium lactate, sodium citrate, potassium chloride, potassium lactate, potassium citrate, , Magnesium sulfide and the like is used to modify the insoluble calcium alginate polymer with water-soluble hydrogel alginate.

In the calcium alginate polymer fiber, calcium is present as an insoluble calcium alginate polymer through ionic bonding with an alginate polymer. In this case, potassium (K), magnesium (Mg), and sodium Na), the calcium alginate polymer fibers are converted into water-soluble alginate fibers by modifying the insoluble calcium alginate polymer with water-soluble alginate by replacing the calcium ions with the metal alginate polymer.

On the other hand, such modification by the substitution reaction can be carried out by combining the above metal salts with each other or in a predetermined ratio to prepare purified water, allantoin, adenosine, arginine, 1,3-butylene glycol, panthenol, glycerin, 60 hydrogenated castor oil or hydroxyethyl cellulose, and the calcium alginate polymer fiber and the heterogeneous fiber are blended with each other to form an alginate nonwoven mask pack, Is impregnated with the essence liquid.

Here, the metal salt concentration of the essence solution is preferably 0.01 to 50% by weight.

Meanwhile, in the present invention, the alginate nonwoven mask pack is prepared in a sheet form by blending calcium alginate polymer fibers and different types of fibers, and the different types of fibers include at least one kind selected from the group consisting of regenerated fibers and natural fibers to be.

In the alginate nonwoven mask pack, 10 to 99% by weight of heterogeneous fibers are preferably added, and 10 to 90% by weight of heterogeneous fibers are most preferably added.

In the present invention, the above different kind of fibers are composed of regenerated fibers such as cellulose fibers and rayon fibers, and natural fibers such as cotton fibers, hemp fibers, silk fibers and bamboo fibers instead of the fibers made of synthetic resin, The water soluble hydrogel alginate modified from the insoluble calcium alginate polymer in the alginate polymer fiber can prevent the elution of the chemical component of the synthetic resin, thereby minimizing troubles due to skin irritation.

As described above, the present invention can maintain the activity of the active ingredient contained in the hydrogel cosmetic liquid for a long period of time through the formation of the micro-film of the water-soluble alginate component and the high water retention, Moisturizing, strengthening skin barrier, and anti-inflammation.
