Description

Chitosan Mask Pack Comprising Functional Natural Plant Extracts}

The present invention relates to a chitosan mask pack containing a functional natural plant extract, and more particularly, to a chitosan mask pack composed of a chitosan nonwoven fabric containing chitosan and a lotion containing a functional natural plant extract applied to the chitosan nonwoven fabric.

Chitin, which can be obtained from natural resources such as crab shells or squid cartilage, has long been used as a folk remedy for wounds. No solvent has been found that is stable and suitable for dissolving or swelling.

On the other hand, chitosan is obtained through a deacetylation process of chitin, which is abundant in crustaceans, and the molecular structure of chitin and chitosan is very similar to that of cellulose. In other words, cellulose has a hydroxyl group (-OH), chitin has an acetamide group (-NHCOCH ₃ ), and chitosan has an amino group (-NH ₂ ) bonded to the C2 position of the pyranose ring, but the rest of the structure is the same. have

The chitosan is known to have excellent biocompatibility, anti-inflammatory and antibacterial effects, etc., and has an amino group (-NH2), so it is easy to modify to other functional groups and dissolves in weak acid aqueous solutions, so it has been used for various purposes in various industrial fields in recent years. is being applied

In addition, the chitosan exhibits strong positively charged electrical properties at pH<6.5, and it is known that cationic chitosan binds to anionic cell membranes of bacteria to exhibit antibacterial effects. In other words, an ionic bond occurs between the amino group of cationized chitosan and the negative charges of sialic acid and phospholipids that water the cell walls of microorganisms. As a result, the protoplasm within the cell is exposed and the microorganism is killed. As long as the ammonium cation (NH ₃ ⁺ ) of chitosan can contact the microorganism, the antimicrobial and antibacterial effect is maintained.

In addition, polymeric water-soluble chitosan has excellent moisturizing properties and affinity, and since it is a cationic polymer and has (+) ions, it has better viscosity than non-ionic polymers, and has excellent emulsion stability, dispersion stability, and binding properties. It is also in the limelight as an applied material for cosmetics.

Recently, a mask pack using such chitosan has been developed. For example, Korean Patent Registration No. 10-1149061 (hereinafter referred to as "Patent Document 1") uses a natural polymer, insoluble chitosan polymer, as a water-soluble hydrogel. It is modified with gelled chitosan and applied to a mask pack material to disclose a chitosan nonwoven fabric for mask pack material having excellent skin beauty effect and improved physical properties and functionality, Korean Patent Registration No. 10-2052921 (hereinafter referred to as "Patent Document 2") Discloses an antibacterial chitosan nonwoven fabric and a mask pack in which a nonwoven fabric containing chitosan is manufactured with water-soluble salt and at the same time, antibacterial, whitening, and anti-wrinkle functions are imparted.

However, in the case of Patent Document 1, the water solubility of chitosan is secured by modifying the molecular chain terminal functional group of chitosan using anhydrous acid, and a hydrogel is formed to adhere to the skin, and antibacterial and moisturizing effects by chitosan can be expected. , Skin trouble may occur due to skin adhesion, and especially, there is a problem in that air enters between the sheet and the skin and lifts as time goes by due to its weak durability.

In addition, in the case of Patent Document 2, a metal / amino acid is complexed with the amino group of chitosan, while anti-aging substances, whitening substances, etc. form an ionic bond with the amino group of chitosan, so the antibacterial property due to the amino group of cationized chitosan is lowered. There is, and the antibacterial chitosan nonwoven fabric prepared according to Patent Document 2 is used as a mask pack after soaking in water. Although the water solubility of chitosan is improved by acid treatment, when attached to the skin, the water evaporates easily. There is a problem of poor durability.

In addition, recent cosmetic compositions contain various functional natural plant extracts. For example, Korean Patent Registration No. 10-2334348 (hereinafter referred to as "Patent Document 3") describes skin moisturizing of a mixed extract containing medicinal wheat. Korean Patent Registration No. 10-1828023 (hereinafter referred to as "Patent Document 4") discloses a cosmetic composition for moisturizing and skin soothing effects of a cosmetic composition containing a mixed extract containing passion flower. Korean Patent Registration No. 10-1584742 (hereinafter referred to as "Patent Document 5") discloses a cosmetic composition for improving skin aging containing nettle extract, and Korean Patent Publication No. 10-2004-0035364 (hereinafter referred to as "Patent Document 6") discloses a whitening composition containing Gaza extract, and Korean Patent Registration No. 10-1988102 (hereinafter referred to as "Patent Document 7") discloses a Korean Patent Publication No. 10-2021-0045670 (hereinafter referred to as "Patent Document 8") discloses a cosmetic composition for relieving skin irritation containing Ojuk juice. Registered Patent No. 10-2313646 (hereinafter referred to as "Patent Document 9") discloses a cosmetic composition for skin whitening containing a mixed extract containing western pepper, and Korean Patent No. 10-2165567 (hereinafter referred to as , "Patent Document 10") discloses a cosmetic composition containing an extract of holy basil leaves and having excellent skin moisturizing effect.

The inventors of the present invention have an antibacterial effect in common with medicinal wheat, passionflower, nettle, gaza, astragalus, ojuk, horseradish, and holy basil leaves disclosed in Patent Documents 3 to 10, so that they can be used as a natural preservative for lotion. It was experimentally verified that whitening, moisturizing, skin soothing, and wrinkle improvement functions could be exhibited depending on the type of plant and plant, and chitosan non-woven fabric with antibacterial effect by chitosan and antibacterial effect of lotion separately packaged. The present invention has been led by focusing on the fact that it can impart whitening, moisturizing, skin soothing, and wrinkle improvement functions.

Korean Patent Registration No. 10-1149061 Korean Patent Registration No. 10-2052921 Korean Patent Registration No. 10-2334348 Korean Patent Registration No. 10-1828023 Korean Patent Registration No. 10-1584742 Korean Patent Publication No. 10-2004-0035364 Korean Patent Registration No. 10-1988102 Korean Patent Publication No. 10-2021-0045670 Korean Patent Registration No. 10-2313646 Korean Patent Registration No. 10-2165567

The chitosan nonwoven fabric is a nonwoven fabric containing 10% by weight or more of chitosan, and if the chitosan is included in 10% by weight or more, there is no particular limitation on the manufacturing method of the chitosan nonwoven fabric.

On the other hand, the soluble-insoluble transition of chitosan occurs at pH 6 to 6.5. That is, chitosan is poorly soluble in alkaline solvents with a pH of 7 or higher, but dissolves well in weakly acidic solutions with a pH of 6 or lower. In addition, chitosan exists in a colloidal state in a weakly acidic solution, and gelation or swelling occurs when the pH is increased.

Therefore, in the present invention, when the lotion is applied to the chitosan nonwoven fabric by making the pH of the skin lotion separately packaged with the chitosan nonwoven fabric higher than the pH of the chitosan nonwoven fabric, the chitosan of the chitosan nonwoven fabric is reduced by the lotion water. As the pH rises while being dissolved, gelation or swelling of chitosan occurs.

However, in the present invention, after sufficiently soaking the chitosan nonwoven fabric in the lotion, applying it to the skin (face) of the human body to perform a test (sensory evaluation), if the pH of the chitosan to which the lotion is applied is too low, the chitosan Viscosity increased and stickiness occurred, and when the pH was too high, the viscosity of chitosan was lowered and dripping occurred. appear.

Therefore, in the chitosan mask pack of the present invention, the pH of the chitosan nonwoven fabric is adjusted to 3.5 to 4.5, and the pH of the lotion water is adjusted to 5.5 to 6.5, but when the lotion is applied to the chitosan nonwoven fabric, the pH is 5 to 6. It is preferable to adjust to .
