## Abstract

Disclosed are a phytoncide moisturizing liquid composition, a hydrogen-generating skin care spray device including the same, and a method for preparing the same, wherein a phytoncide moisturizing liquid composition, which contains, on the basis of the total weight of the composition, about 95-98 wt % of water, about 1-3 wt % of a phytoncide undiluted liquid, about 0.05-0.5 wt % of gamma poly L glutamic acid, about 0.05-0.5 wt % of chitosan, and about 0.1-2 wt % of an emulsifier, is mixed with hydrogen generated by a hydrogen generator, thereby maximizing, at one time, the effect of the phytoncide moisturizing liquid composition, which is capable of suppressing the increase in collagenase in the skin due to ultraviolet radiation, and the effect of the hydrogen, which suppresses melanin synthesis by ultraviolet radiation and makes active oxygen generated due to the ultraviolet radiation harmless to the human body.

## Claims

### Claim 1

A skin care spray device for hydrogen generation, comprising:
a hydrogen-generating ceramic filter comprising a porous ceramic container containing magnesium fragments, one opened end of which is sealed with a ceramic cap, so as to prevent external leakage of the magnesium fragments;
an aluminum pouch containing the hydrogen-generating ceramic filter and a phytoncide moisturizing liquid composition and provided with a check valve for preventing the phytoncide moisturizing liquid composition from running back from an upper part of the aluminum pouch;
a cylindrical aluminum can, an open upper part of which is coupled with the upper part of the aluminum pouch; and
a nozzle for spraying the phytoncide moisturizing liquid composition filled in the aluminum pouch, the nozzle being mounted on an upper part of the aluminum can.

### Claim 2 (depends on 1)

The skin care spray device according to claim 1, wherein the cylindrical aluminum can having been sealed comprises air having a predetermined pressure therein, wherein the pressure of the air is 6 to 9 bar.

### Claim 3 (depends on 1)

The skin care spray device according to claim 1, wherein the phytoncide moisturizing liquid composition comprises 95 to 98% by weight of water, 1 to 3% by weight of an undiluted phytoncide oil, 0.05 to 0.5% by weight of gamma-poly L-glutamic acid, 0.05 to 0.5% by weight of chitosan, and 0.1 to 2% by weight of an emulsifier, based on a total weight of the phytoncide moisturizing liquid composition.

### Claim 4 (depends on 3)

The skin care spray device according to claim 3, wherein the phytoncide moisturizing liquid composition further comprises 0.1 to 2% by weight of a botanical extract.

### Claim 5 (depends on 4)

The skin care spray device according to claim 4, wherein the botanical extract is an aloe extract or a citrus oil.
