Description

BLACK HEAD REMOVING PATTERN LAMINATE AND TWO-PART NORMAL PACK PATCH {PATCH LAMINATE FOR REMOVING BLACK HEAD AND TWO PART NOSE PACK PATCH}

The present invention relates to a method for producing a blackhead-removing patch laminate and a blackhead-removing patch laminate in which a heat-generating layer, a sebaceous-dissolution layer and an adsorption layer are sequentially laminated, Lt; / RTI > patch.

The sebum is made in the sebaceous glands and then released through the pores. The sebaceous gland functions as an anti-bacterial action to protect our body from external bacteria by forming a fatty membrane on the surface of skin and hair, protecting skin from ultraviolet rays or moisturizing the skin. In sebaceous glands, sebaceous glands are increased If a problem occurs during the passage through the pores, the pores are enlarged. In addition, when applying make-up in the presence of sebum, the dispersibility of the cosmetic composition becomes poor, and the cosmetic effect can not be sufficiently exhibited.

Furthermore, when the pores are enlarged, the enlarged pores become filled with sebum, and these sebum are entangled with keratin or dust. The sebum component thus entangled is oxidized when it comes into contact with air, thereby discoloring to form a black head. Blackheads occur when the skin is irritated or exposed to ultraviolet rays and mixed with external dirt. In particular, the area around the kona ball is more exposed to external stimuli such as ultraviolet rays, .

Accordingly, conventionally, as a method of removing sebum occurring on the face and a specific site, a method of removing sebum using a stain removal paper or removing sebum by cleansing has been used. Conventional stock removal stocks were made using plastic materials such as paper and thermoplastic polymers as common raw materials.

For example, a paper-made staple removing paper can be produced by using vegetable fibers having absorption ability such as hemp, synthetic pulp, kenaf, etc. However, since the paper removing staple paper has hardness and surface roughness There was a big disadvantage that it could stimulate the skin. In addition, the paper-based stock removal eliminator has a relatively small capacity for absorbing the staple, and the appearance of the paper hardly changes even if the paper is absorbed. Therefore, it is also difficult to confirm the degree of absorption of the sebum, that is, the removal state of sebum.

 In addition, as another method, Japanese Patent Laid-Open No. 1993-097627 discloses a burying agent containing a polymer compound having a salt generator. Since it depends mainly on the removal power of the sebum by the cationic polymer, the bonding strength is low, And also a peel off type tangle remover and a sheet type tangle remover for the purpose of removing dirt and pores in the pores are widely used as disclosed in Korean Patent Publication No. 2000-0006074 . However, it is a relatively difficult problem to apply the electromotive remover to the face evenly as the finger becomes dirty with the electroretinizer. Further, it takes a long time to dry the applied remelting remover, and there is a problem that a part of the remelting remover remains on the skin when the dried remelting remover is stripped from the face.

Also, the blackheads accumulated in the pores are not easy to remove, and even if they are removed or treated, they are replenished in a short period of time and become larger pores. A method of removing a blackhead generally uses a hard swab, a sebum removing machine, or a pore clear toner, etc., and physically removes it by applying a force. In addition, even if the blackhead is removed, since the pores remain untreated or widened, fundamentally, it is necessary to perform additional treatment or proper skin care to shrink the pores.

Accordingly, there is a need to develop a product which can dissolve sebum at the same time as pore enlargement, has a high sebum adsorption degree, and can reduce pores after sebum adsorption.

In the case of Comparative Example 1 in which the heating layer is not constituted in the structure of the patch laminate for blackhead removal according to the present invention as described above, it is difficult to remove the sebum due to the inability to expand the pores through heat transfer, Even if the patch was used, it was confirmed that the pore size shrinkage effect was remarkably low. In the case of Comparative Example 2 in which the adsorption layer was not constituted in the structure of the patch laminate for blackhead removal, it was confirmed that even if the sebum dissolves, the sebum in the pore is not removed and the sebum remaining in the pore is not reduced Respectively.

Therefore, it was confirmed that the effect of removing the sebum was maximized when the patch laminate for removing blackhead of the present invention was used, and the pore-reducing effect was also excellent by using the second patch for reducing pores.

As described above, according to the present invention, the patch laminate for blackhead removal and the two-pack type nasal patch are described through the specified matters and the limited embodiments.
