Description

Hydrogel pack composition and mask pack using the same {COMPOSITION FOR HYDROGEL MASK PACK AND MASK PACK PREPARED FROM THE SAME}

The present invention relates to a hydrogel mask pack, a preparation method thereof, and a composition used in the preparation thereof, and more particularly, a formulation that flows out like a mucus, and has an excellent skin adhesiveness of the active ingredient that flows out intensively even in a short time. It relates to a hydrogel pack composition and a mask pack applying the same to help health.

In general, the cosmetic mask pack is made by adding water or a lotion to the nonwoven fabric or an extract known to be functional, or the hydrogel mask pack has been actively researched to overcome the disadvantages of the nonwoven mask pack. In order to maintain the appearance of the mask pack, it was common to add hydrogels to synthetic resins, nonwoven fabrics, meshes, and nets. However, the hydrogel is often separated from the nonwoven fabric, and in the case of the hydrogel using synthetic resin, there may be a problem in terms of biocompatibility and stability.

As a result, a lot of hydrogel mask packs using materials derived from nature have been studied to overcome the above problems of biocompatibility. In the case of the natural hydrogel mask pack, since the substance itself is produced in the form of a film without using synthetic resins such as non-woven fabrics, it does not have side effects such as itching of sensitive skin caused by non-woven fabrics or synthetic resins, and directly on the skin. There is an advantage that can provide an impact.

The diluent eluted from the hydrogel pack can adjust the strength of the gel, control of the outflowing time, control of the amount of diluent flowing out, and the components and viscosities mixed with the diluent depending on its composition, component, and content. Since the diluent of the existing hydrogel is only water is discharged, the retention of moisture, adhesion, feeling, and retention after use of the hydrogel are inferior.

Therefore, in order to overcome the problems described above, by improving the physical properties of the diluent liquid eluted from the hydrogel pack, the situation for the hydrogel pack that can maintain the moisturizing feeling, adhesion, feeling and after use moisturizing power when using the hydrogel is urgently needed.

An object of the present invention relates to a hydrogel pack composition and a mask pack to which the active ingredient is eluted from the hydrogel, such as mucus, and the active ingredient flowing out helps skin health intensively even in a short time due to excellent skin adhesion.
