Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has excellent fluidity of a preparation,
In addition, the present invention relates to a bath agent that is smooth when bathing and that has a sufficient moisturizing effect on the skin after bathing.

[0002]

2. Description of the Related Art Conventionally, bathing has the effects of cleaning the body, promoting blood circulation, and relaxing mentally.
It greatly contributes to recovery from cold and fatigue. However, the bath may lose oil, NMF components (natural moisturizing factor: a substance having a moisturizing effect contained in the skin), etc. from the skin. In that case, dryness of the skin after bathing may occur in people with dry skin. Skin diseases (senile xerosis, atopic dermatitis, etc.)
It can be a problem for people with. Due to such problems, recently, it has been desired to have a smooth feel when bathing and to moisturize the skin after bathing, and various bath agents containing an oily component in order to meet the demand, Proposed.

However, in order for the liquid or pasty oily component to exert its effect, a large amount of them must be blended, the fluidity of the preparation is lowered, and during manufacture, storage, and further, Problems often occur during use. Therefore, in order to avoid these problems, silicic acids have been conventionally used as an oil-absorbing agent, but since silicic acids are basically insoluble in water, there is a problem that the bath water becomes dirty and the user feels uncomfortable. was there. In recent years, in order to solve these problems, an invention for improving fluidity by using saccharides has been published (JP-A-3-58921). However, in order to maintain fluidity, it is at least 5 times that of the oily component. The weight of saccharide must be used, and the cost becomes high, and there is a problem that the fluidity deteriorates over time (caking), and when the amino acid that is a moisturizing component coexists with the saccharide, a Maillard reaction occurs. However, there is a problem in that the color changes and the product value is impaired.

[0004]

Under the circumstances, the present invention provides a bath agent having excellent fluidity, smoothness during bathing, and sufficient moisturizing effect on the skin after bathing. The challenge is to provide.

[0005]

Means for Solving the Problems As a result of intensive studies to obtain the above-mentioned bath agent, the present inventors have found that in a bath agent containing an inorganic salt as a main component, an oily component and a glycoside crude drug powder are extracted. It has been found that the above problems can be solved by blending the above, and the present invention has been completed. That is, the present invention provides a bath agent composition comprising an inorganic salt as a main component, and an oily component which is liquid or paste at room temperature and an extracted powder of a glycoside crude drug. Less than,
The present invention will be described in detail.

The inorganic salts used in the present invention include sodium sulfate, sodium hydrogencarbonate, sodium carbonate, sodium sesquicarbonate, sodium chloride, ammonium chloride, sodium nitrate, sodium polyphosphate,
Sodium phosphate, calcium oxide, calcium carbonate,
Magnesium oxide, magnesium sulfate, aluminum sulfate, magnesium carbonate, potassium chloride, potassium sulfide,
Alum and the like can be mentioned, and one or two or more kinds can be appropriately selected and blended depending on the moisturizing ability of the salt. Of these, sodium sulfate, sodium hydrogen carbonate, sodium carbonate and sodium chloride are preferable. The compounding ratio to the total composition is 10 to 95% (by weight), preferably 5
0 to 95% (weight).

Examples of the oily component used in the present invention include lanolin, liquid lanolin, jojoba oil, squalane, orange laffy oil, petrolatum, liquid paraffin, liquid isoparaffin, olive oil, macadamian nut oil and other natural oils, synthetic oils, silicones. Examples thereof include those alone or two or more kinds can be appropriately selected and blended. Of these, squalane, jojoba oil and macadamian nut oil are preferred. The compounding ratio to the total composition is 0.1 to 20% (weight)
However, it is preferably 1 to 10% (by weight). If the blending ratio is too small, the smoothness at the time of bathing and the sufficient moisturizing effect on the skin after bathing cannot be obtained, and if it is too large, the skin becomes sticky, which is not preferable.

[0008] The glycoside crude drug used in the present invention is birch, hawthorn, ginkgo, haggi, ononis, soybean, elderberry, spirea, bodige, violet, nazuna, licorice, sardine, age, spruce, moss, pheasant, syrup, chimp. , Cuckoo, carrot, sucrose, horse chestnut, horse chestnut, pearl millet, horsetail, western amberjack, kiraya, primrose, cyclamen, senega, etc., alone or 2
It is possible to appropriately select and blend one or more species. Among them, cockpi, ages, liquorice, and braces are particularly preferable.
These extraction powders can be obtained by drying and pulverizing an extract extracted with water, hot water, a solvent or the like or a fractionated product obtained by a conventional method.

The blending ratio of the crude drug extract powder to the total composition is 0.1 to 10% (by weight), preferably 0.5 to
It is 5% (weight). If this blending ratio is too small, the desired effect will not be obtained, and if it is too large, the improvement of the effect commensurate with the increased amount cannot be expected. In addition, the blending ratio of the above oily components is such that the amount of the oily components is 0.005 times that of the crude drug extract powder.
It is 200 times, preferably 0.2 times to 10 times.

The non-sugar portion of the glycoside crude drug is preferably sapogenin and / or flavonoid. The glycoside is preferably contained in the crude drug extract powder in an amount of 30% (by weight) or more, but a higher purity is preferable for the purpose, and when it is 40% (by weight) or more, the physical properties are considerably improved. It

Further, in addition to the above components, surfactants, polymers, organic acids, vitamins, enzymes and the like can be added to the bath agent composition of the present invention, if necessary. Specific examples thereof are shown below. Examples of the surfactant include sodium lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, polyoxyethylene alkyl ether sulfate, lauric acid diethanolamide, and polyoxyethylene glycol monostearate.

There are C, D, E, etc. Enzymes include papain, pepsin, trypsin, ficin, pancreatin and the like.
In addition, pigments, fragrances, fine powders for cosmetics and the like can be used.

Any mixer can be used as long as it is used for stirring and mixing powders.
Specific examples thereof include a Bad O mixer, a Nauta mixer, a universal mixer and a mixer, a ribbon mixer, and a V-shaped mixer. The mixing time may be any time required for uniformly mixing the components, and when the mixer described in the above example is used, it is usually 5 to 50 minutes. The dosage form of the present invention is not limited to powder, granules and tablets.

[0014]

In the bath agent composition of the present invention, a liquid or pasty oily component is impregnated into the powder of the glycoside crude drug impregnated, so that the fluidity derived from the oily component is prevented from decreasing during the manufacturing process. it can. Alternatively, due to the same effect, the liquidity can be kept smooth during storage and use. In addition, glycoside crude drugs have the effect that blood vessels of the skin are expanded and blood circulation is promoted, and have the unique scent and sedative effect of crude drugs. I am doing it. It should be noted that the above-mentioned effects are most exerted at the blending ratio of each component of the present invention.

[0015]

EXAMPLES Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.

Examples 1 to 4 and Comparative Examples 1 to 3 The powdery bath agent compositions having the component compositions shown in Table 1 were mixed by a conventional method, and the performance and sensory evaluation thereof were carried out as follows.
