The present invention relates to a tablet for preparing a hydrogel mask pack and a functional hydrogel mask pack prepared using the same.

Hydrogels are also referred to as hydrogels, and they form three-dimensional bridges by the physical (hydrogen bonding, van der Waals force, hydrophobic interaction, or polymer crystallization) or chemical (covalent bonding) Refers to a material that is not dissolved in the aquatic environment and can contain a significant amount of water. Since hydrogels can be made from various water-soluble polymers, they have various chemical compositions and physical properties. It is also easy to process and can be modified into various forms depending on the application. Hydrogels have high biocompatibility due to their high water content and physico-chemical similarity to the extracellular matrix, as can be seen in successful applications in the peritoneum and in vivo. Because of these properties, hydrogels are attracting attention as one of the most attractive materials in medical, pharmacological and cosmetic applications.

The skin-beauty agent using the hydrogel is required to rapidly transfer the active ingredient contained in the hydrogel within a short time of 20 to 30 minutes after the hydrogel is applied to the skin. However, for this purpose, the active ingredient in the hydrogel is rapidly It should have characteristics that are evenly distributed. However, as long as the effective cosmetic ingredient in the gel, which maintains the hydrogel state, is transferred from the hydrogel to the skin, it is limited in satisfactory quantity and speed, so that the moisture and the active ingredient in the hydrogel are evaporated over time It becomes dry and it can not enjoy the effect. Therefore, even if the hydrogel has a unique adhesive property and wettability, the limit of the effective ingredient contained in the hydrogel and the limit of the delivery speed of the effective cosmetic ingredient to the skin is not limited to the skin penetration efficiency of the hydrogel skin cosmetic agent It is bound to have a limit.

Korean Patent Laid-Open Publication No. 10-2016-0055542 (Patent Document 1) discloses a method of adding an essence to a molded article made from a proprietary hydrogel mask pack composition to add various effective ingredients with improved strength and being sensitive to temperature A hydrogel mask pack is disclosed. However, since the hydrogel mask pack must be mixed, heated, cooled, dried, and cut to form the hydrogel mask pack, the manufacturing process is complicated. In particular, since it is provided in the form of a completed mask pack containing moisture, it is not only inconvenient to store and distribute, but also to contain refrigerant as well as to contain essential preservative for long-term distribution and storage. Peptide tablets produced in China have also been disadvantageous in that a mask pack is formed using a mask pack maker, and the pills themselves have no functionalities such as skin beauty improvement. Korean Patent Laid-Open No. 10-2015-0089955 discloses a method of preparing a mask pack on the spot, but merely dissolves the mixed composition in water, It has a disadvantage in that it is difficult to quantify the amount to be dissolved and the mixture of the mixed powder state must be dissolved in water before hardening.

The inventors of the present invention have developed a tablet for preparing a mask pack in which a functional raw material and a polymer mixture are mixed so as to prepare a hydrogel-type mask pack when dissolved in water.
