BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath cosmetic which is non-irritating to the skin, promotes blood circulation, enhances perspiration, has an excellent heat retaining effect, and has a beautiful skin effect.

[0002]

2. Description of the Related Art Conventional bath cosmetics mainly contain so-called inorganic salts such as sodium sulfate, sodium hydrogencarbonate, sodium chloride and the like, and include fragrances, oils, pigments and the like. Auxiliary components are appropriately blended to refresh the mood during bathing, promote blood circulation,
A wide variety of products are on the market to increase metabolism. However, current bath cosmetics promote blood circulation and enhance the metabolism, and have a sweating effect, heat retention effect,
In addition, there is a problem that it is not sufficient to obtain an excellent skin effect.

[0003] A bath preparation, which is one of bath cosmetics, for obtaining a sweating effect and a heat retaining effect by promoting blood circulation and enhancing metabolism, and further obtaining an excellent skin effect, is based on 200 l of hot water in a bathtub. Usage amounts of 25 g to 30 g are common. However, in order to obtain a sufficient sweating and warming effect to promote blood circulation or enhance metabolism, the hot water in the bathtub 200
A method of increasing the amount used per 1 or increasing the crude drug component, which is one of the active ingredients, can be considered. However, when the amount of use is increased or the effective ingredient is increased, there are drawbacks such as strong irritation to the skin, defatting with an alkali component of an inorganic salt, and roughening of the skin.

On the other hand, recently, there has been a tendency to prefer a liquid bathing agent, and many oil-based ingredients which are put into a bath tub and emulsified and become cloudy milk-like or those mainly comprising a humectant have been developed.

[0005] Also, with the recent spread of showers, the number of bubble baths that wash the whole body only with a shower without being immersed in the bathtub or that are foamed when hot water is poured into the bathtub has been increasing as European and American lifestyles and customs have increased. . Further, there is an increasing demand for bath cosmetics that can be applied to the whole body at the time of showering and washed off to obtain a refreshing feeling and a moist feeling.

[0006] As the aging society progresses, the bedridden population requiring nursing care is increasing, and among them, the effect of a foot bath, which is regarded as important as bathing, is attracting attention and is spreading. In addition, demand for foot baths has been increasing as a method of removing swelling of legs due to daily stress such as complete air conditioning and work, and recent work, and development of foot bath agents has been strongly desired.

[0007] Accordingly, an object of the present invention is to provide a bath cosmetic which is non-irritating to the skin, promotes blood circulation, enhances perspiration, has an excellent heat retaining effect, and has an excellent skin effect. It is in.

[0008]

m, area 3681m ² , average water depth 4m, salt concentration about 20-2
The main component of the lake water, 5%, is sodium chloride, a salt lake known as the lake with the highest salt concentration next to the Dead Sea. It is estimated that this salt lake produces algae, shrimps, etc. as living things and stores 6 billion tons of salt.

The lake water used in the present invention is the lake water of the salt lake, which is dissolved in water from surrounding mountains such as the Rocky Mountains and flows into Salt Lake, and contains abundant minerals. About 84 types of minerals have been identified.

The lake water (hereinafter abbreviated as GSL-W) may be used as it is, or after filtration with a filter as necessary, to remove harmful metals, sterilized by heating, and filled in a container.

As a dried product of lake water (hereinafter abbreviated as GSL-S), GSL-W is dried in the sun and washed several times.
What was dried again, after drying the filtrate by hot air drying with a spray heat drier, pulverized into a powder, freeze-dried as it was quickly frozen and the like, and particularly preferred is stability. In order to reduce the amount of salts that cause stickiness as required, desalting treatment may be performed using a so-called reverse osmosis membrane, freeze-dried, and pulverized.

The GSL-S or GSL-W is composed of various salts (anions such as chlorine, sulfuric acid, bicarbonate and bromine and cations such as sodium, magnesium, calcium, potassium, iron, cobalt, selenium and manganese). In addition, it contains natural iodine, arsenic, polysaccharides, amino acids, vitamins, and the like, and these components penetrate into the skin to give a moist and moist feeling. In addition, the GSL-S or GSL
The dried product of -W has much water insolubility and is less irritating to the skin than the salt of the Dead Sea, and has a good feel to the skin.

The desalted GSL-W and GSL-S
Contains more than twice the amount of organic matter, except that chlorine and sodium are reduced as compared with those obtained by freeze-drying seawater or salt from the Dead Sea. In addition, desalinated one is particularly preferable in terms of workability or stability when blended in a product, and further, if necessary, for example, an inorganic salt such as dextrin or sodium sulfate as a binder, or sodium carboxymethylcellulose. It is preferable to granulate using such a thickener and the like.

The present invention will be described in detail below based on examples and comparative examples.

(Preparation method of lake water or salt thereof obtained from Great Salt Lake) 5 Kg of lake water was heated for 1 hour, a small amount of bleach was added, and the mixture was stirred for 15 minutes, filtered to remove impurities, and then subjected to filtration (sample GSL). -W1). It is also cooled. This was freeze-dried, and the resulting solid was pulverized to obtain about 50 g (sample GSL-S1). Before freeze-drying, the solution was reduced in salt using a reverse osmosis method, and then freeze-dried. About 30 g (sample GSL-S2) of lake water obtained from the desalted Great Salt Lake or its dried product was obtained. The lake water obtained from the desalted Great Salt Lake or a dried product thereof is shown in the range of the content because some variation in the component content occurs due to the collected lake water.

Example 1 and Comparative Example 1 A bath agent having the composition shown in Table 2 was used in Example 1 and Comparative Example 1.
And evaluated. The production method followed the method of a usual bath agent.

[0036]

[Table 3]

[0037] The evaluation method was such that 10 persons were evaluated for feeling during bathing, feeling after bathing, and skin condition after continuous use for one week. Approximately 200 l of hot water at 40 ° C. was placed in a bath, 30 g of each of the bath cosmetics having the compositions of Example 1 and Comparative Example 1 was charged, and the bath was bathed for 10 minutes. Very good 5
The points of 4 points, good 4 points, ordinary 3 points, no change 2 points, and bad 1 point were entered and averaged. Table 4 shows the results.

[0038]

[Table 4]

From Table 4, it is clear that Example 1 is Comparative Example 1
Feels better on the skin while bathing, no irritation,
It is evident that the skin after bathing has a glossy and moist feeling (moisturizing property) and is excellent in beautiful skin effect. Also, sweating action,
Example 1 was also superior to Comparative Example 1 in the heat retention effect.

Example 2, Comparative Examples 2 to 4 Examples 2 and Comparative Examples 2 to 4 shown in Table 5 were compared with a fresh water bath in which no active ingredient was added to the bathtub. About 200 l of hot water at 40 ° C. was put into the bathtub, and 30 g of each of Example 2 and Comparative Examples 2 to 4 was put in the freshwater bath as it was, and the bath was taken for 15 minutes. Bathing bath temperature is 40 ° C, bathing time is 5 minutes,
In a constant temperature and humidity room at 25 ° C. and 60%, the sweating effect was determined based on the amount of water transpiration in the forehead as the amount of perspiration. The measurement was performed using a ventilation capsule having an area of 1 cm ² . (2)
For the evaluation of the heat retention effect, the temperature of the chest was measured by a thermograph manufactured by NEC Sanei. (3) The sample was placed in a glass container, stoppered, and then placed in a constant temperature, 40 ° C., 75% constant humidity chamber for 3 months to observe the solidification state of the sample. The preparation of the sample was in accordance with the usual method of bath cosmetics. The numerical values in the table represent% by weight.
