DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventional bath compositions mainly contain so-called inorganic salts such as sodium sulfate, sodium hydrogen carbonate, sodium chloride and the like, and further contain 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 enhance metabolism. However, the current bath composition has a problem that it is insufficient to obtain a sweating effect, a warming effect and an excellent skin effect by promoting blood circulation and increasing metabolism.

On the other hand, a bath composition for promoting perfusion and enhancing metabolism to obtain a sweating effect, a warming effect, and a more excellent skin effect is used in an amount of 25 g to 30 g per 200 l of hot water in a bathtub. Is common. However, in order to obtain a sufficient perspiration / warming effect to promote blood circulation or enhance metabolism, it is conceivable to increase the amount of water used for 200 l of hot water in the bathtub or to increase the amount of a crude drug component, which is one of the active ingredients. Can be However, when the amount of use is increased or the effective ingredient is increased, there is a disadvantage that the alkali component of the inorganic salt is degreased or the skin becomes rough.

In view of the above circumstances, as a result of diligent studies on bath compositions which promote blood circulation, enhance perspiration, have an excellent heat retaining effect, and have a beautiful skin effect, diisopropylamine dichloroacetate was added to seawater dried product and silicic anhydride. Have been found to enhance the sweating, warming and beautiful skin effects by adding a compound, which has led to the completion of the present invention. The purpose of the present invention is to provide a bath composition which promotes perspiration, enhances perspiration, is excellent in heat retention effect, and is excellent in beautiful skin effect (gloss, texture and moist feeling).

[0005]

The amount of diisopropylamine dichloroacetate used in the present invention is suitably from 0.1 to 20% by weight based on the total amount of the bath composition.
Particularly, 0.5 to 10% by weight is preferable. If the amount is less than 0.1% by weight, the manifestation of the effect is not sufficient, and if it is more than 20% by weight, it is not suitable in terms of cost.

Examples of the dried seawater used in the present invention include natural salts obtained by reducing the water content of seawater, or those obtained by directly drying seawater or freeze-drying seawater, while maintaining the quality stability of the bath composition. In order to reduce the amount of salts that cause stickiness as necessary, desalination treatment using a so-called reverse osmosis membrane or the like, freeze-drying and pulverized seawater dried product is particularly preferable.

The desalted seawater dried product is rich in so-called trace elements such as magnesium, potassium, phosphorus, etc., in addition to a decrease in chlorine and sodium as compared with a product obtained by freeze-drying seawater as it is. I have. In addition, since the desalted seawater dried product has a reduced amount of salts that cause stickiness as described above, the desalted seawater dried product is required to maintain the workability when blended into the bath composition or the quality stability of the bath composition. Particularly preferred.

The amount of the dried seawater used in the present invention is 10 to 10% based on the total amount of the bath composition.
The content is 90% by weight, particularly preferably 10 to 60% by weight.
If the amount is less than 10% by weight, the effect is not sufficiently expressed, and if it is more than 90% by weight, cost and stability are not suitable.

Dried seawater is highly hygroscopic in terms of physical properties. When flavors, other plant extracts, oils, etc., which are usually added thereto, are added, the composition is solidified at the time of production and the fluidity is poor.
There are drawbacks in working conditions such as difficulty in handling during manufacture, and the appearance of the product is poor and it is difficult to come out of the container smoothly. However, these problems can be solved by adding silicic anhydride.

The silicic anhydride used in the present invention includes:
It may be a known compound produced by reacting an acid with a sodium silicate solution and decomposing it. Examples of commercially available products include commercial products such as Silopure (manufactured by Fuji Divison Chemical Co., Ltd.). Further, the average particle diameter of 2 to 4 microns, which is generally known for these particle diameters, is preferable.

The amount of the silicic anhydride used in the present invention is 0.1 to 0.1% based on the total amount of the bath composition.
The content is 5% by weight, particularly preferably 0.2 to 3% by weight.
When the amount is less than 0.1% by weight, the composition cannot sufficiently exhibit the anti-caking effect, and when the amount is more than 5% by weight, the appearance of the composition upon dissolution is not suitable.

The bath composition of the present invention having the above composition is as follows:
It is possible to provide a bath composition which has no irritating property to the skin, has a beautiful skin effect of making the skin glossy, moist, and moist, and has an excellent effect of promoting blood circulation to enhance a sweating action and a warming effect.
