DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for a bag-filled bath which is not irritating to the skin and has an excellent effect of remarkably improving skin texture, color, luster and the like.

[0002]

2. Description of the Related Art
In order to make the bath comfortable when taking a bath, crushed plant materials such as lemon, tangerine, shobu, yuzu and seaweed are put directly into the bath to enjoy the smell and to promote health. In addition, so-called bath agents such as bath fragrances with these odors, medicinal ingredients and crude drugs effective for heat shrinkage, morbidity, etc., and bath detergents for preventing hot water from becoming dirty or slimy are used. However, if lemon, tangerine, shobu, yuzu, seaweed, etc. are taken directly into the bath, the bath water will be colored or turbid, and cannot be used for washing after bathing, and the bath tub may be used for cleaning dirt. There was a problem that it took time.

[0003] Further, conventional bath preparations are used by adding most of the crushed plant material to the bath water as it is, or by filling the bag into a bag of a non-woven fabric or the like and putting it into the bath water. However, when crushed plant materials are packed in bags of non-woven fabric, etc., the bags are cut and spilled when packed in a coarse state, or spilled from the eyes when packed in a fine state. There is a drawback that the appearance is impaired. In addition, these crushed plant products provide skin texture,
There was also a problem that the effect of improving the color and gloss was insufficient.

The present invention has been made in view of the above-mentioned circumstances, and has no irritation to the skin, and is excellent in the effect of remarkably improving the texture, color, luster and the like of the skin. It is intended to provide a composition.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies to achieve the above object, and as a result, after preserving fresh tea leaves under anaerobic conditions, steam heating treatment and / or drying treatment. The crushed tea leaves obtained by doing so are packed in a bag with a certain particle size, so that the contents do not spill out of the eyes of the bag and impair the aesthetic appearance. The present inventors have found that bathing with a stuffing bath composition has an effect of remarkably improving skin texture, color, gloss, and the like, and completed the present invention.

That is, according to the present invention, the leaves of tea are stored under anaerobic conditions at room temperature for 3 hours or more , and then subjected to a steam heating treatment and / or
Alternatively, it is a composition for a bagging bath, characterized in that a crushed tea leaf obtained by a drying treatment is blended.

Hereinafter, the configuration of the present invention will be described in detail. The bath composition of the present invention can be produced, for example, as follows. That is, the air in the container containing the freshly picked tea leaves is sufficiently replaced with an inert gas such as carbon dioxide gas or nitrogen gas, and then the container is sealed (anaerobic conditions). Then, after leaving it at room temperature for 3 hours or more, it is steam-heated and naturally dried, or dried by a heating dryer. By pulverizing the dried product to a certain particle size, a pulverized tea leaf used in the present invention can be obtained.

[0008] The fresh leaves of tea used in the present invention are:
Any varieties such as alley and fuji can be applied, and the time of plucking is not particularly limited.

The storage time of the tea leaves under anaerobic conditions used in the present invention is preferably from 3 hours to 24 hours at room temperature, more preferably from 5 hours to 15 hours. If the storage time is short, the production of γ-aminobutyric acid or the like is not sufficient, and the above-mentioned effect is not exhibited. The conditions for drying the tea leaves stored under anaerobic conditions are 10 to
After steam heating for 30 minutes, air dry or 8
It is preferable to dry in a dryer at a temperature of 0 ° C. or more for 5 hours to 10 hours.

The particle size of the pulverized tea leaves used in the present invention is preferably adjusted to a particle size passing through a 5-150 mesh sieve, and particularly preferably a particle size passing through a 10-100 mesh sieve. If it is coarser than 5 meshes, it may be broken off from the nonwoven fabric or the like, and the appearance is not good, which is not preferable. On the other hand, if the mesh size is smaller than 150 mesh, it may undesirably exude from the nonwoven fabric during transportation or standing. The water content of the ground tea leaves was 10 wt%.
The following is preferred.

[0011] The tea leaves thus obtained have a high content of γ-aminobutyric acid and its derivatives. However, when the bath composition of the present invention containing this is used at the time of bathing, theophylline having a peripheral vasodilatory effect as a component of tea leaves extracted by hot water in addition to γ-aminobutyric acid and its derivatives, a peripheral nerve stimulating effect And flavonoids having peripheral vascular strengthening and anti-inflammatory effects. As a result, it is expected that the extracted components act synergistically to enhance the skin function.

The amount of the tea leaves obtained by performing the above-mentioned treatment in the present invention is preferably at least 10% by weight (hereinafter abbreviated as wt%) based on the total amount of the bath composition. That is, if the amount is less than 10% by weight, the desired function of the skin for the purpose of the present invention is not promoted and the effect is not exhibited as expected.

In the present invention, any other base ingredients for baths that can be used together with the ground tea leaves can be used as long as they can be generally used, but can be appropriately selected from the following substances according to their efficacy and effects.
