Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excellent bath preparation composition which can provide a firm feeling and a refreshing feeling.

[0002]

2. Description of the Related Art Various components such as oily components, crude drugs, plant extracts, vitamins, and the like have been blended as conventional bath preparations in order to give effects such as smooth, moist, smooth, and refreshing skin feeling. Although a product was provided, a satisfactory bathing agent could not be obtained because it provided a tightening feeling and a refreshing feeling. And there was no means to objectively evaluate those effects.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bath preparation composition which can provide an excellent skin tightening effect and a refreshing feeling on the skin.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found that a bath preparation composition contains one or more salts having a skin extension rate of less than 100% in a skin extension test. It has been found that the above-mentioned problems can be solved by adding at least one plant-derived substance having a specific amount and a skin expansion rate of less than 100% in a skin expansion test, thereby completing the present invention.

That is, according to the present invention, one or more salts having a skin extension rate of less than 100% in a skin extension test are blended in such an amount as to have a concentration in a bath water of 0.15 to 60 ppm. 100% skin extension rate in skin test
A bath preparation composition characterized by comprising one or more plant-derived substances exhibiting less than.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the skin extensibility test of the present invention, a Cutometer manufactured by Courage & Khazaka Germany was used.
Using SEM 474, the maximum pulling height of the skin pulled into the probe suction port (inner diameter 2 mm) when negative pressure was applied at 300 mb for 2 seconds was measured before and after bathing, and the value before bathing (hereinafter referred to as “pre-value”)
) Is taken as 100 and the converted amount (%) after bathing is calculated to be the skin extension rate. The skin extensibility test will be described in more detail. The inner part of the forearm is gently wiped with absorbent cotton impregnated with ethanol, and placed in an artificial environment room (room temperature 25 ° C., humidity 50%).
And acclimatize for 1 hour, and measure the previous value. 40 ° C for forearm
Bath in a test bath (sample concentration: 200 ppm) for 5 minutes. Using a dry towel, gently wipe the water out of the forearm. Twenty minutes after the bath, the inside of the forearm is measured, and the skin extension rate is calculated with the front value as 100.

[0007] The skin extension rate in the skin extension test is 10
As salts showing less than 0%, for example, zinc paraphenol sulfonate, zinc sulfate, zinc sulfocarbonate, zinc oxide (calamine), zinc chloride, zinc hydroxide, zinc carbonate, zinc silicate, zinc phosphate, zinc citrate , Zinc oxalate, ferric chloride, allantoinchlorohydroxyaluminum, allantoindihydroxyaluminum, aluminum chloride, potassium aluminum sulfate (potassium alum), aluminum sulfate, aluminum hydroxychloride, aluminum acetate, aluminum hydroxide, aluminum citrate, etc. . One or more of these can be blended in the bath agent composition of the present invention.

[0008] Examples of plant-derived substances having a skin extension rate of less than 100% in a skin extension test include persimmon tannin, quintuple tannin, hamameli tannin, oak tannin, tara tannin, gallic tannin, perilla tannin and the like. . One or more of these can be blended in the bath agent composition of the present invention.

The skin extension rate in the skin extension test is 10
Salts showing less than 0% have a concentration in the bath water of 0.15%.
It is necessary to mix in an amount of 〜60 ppm.
If the concentration is less than 0.15 ppm, a sufficient effect cannot be obtained, and if the concentration exceeds 60 ppm, an effect corresponding to the cost cannot be obtained.

[0010] The skin extension rate in the skin extension test is 10
It is preferable to mix the plant-derived substance having a concentration of less than 0% in the bath water so as to have a concentration of 0.1 to 150 ppm. If the concentration is less than 0.1 ppm, a sufficient effect cannot be expected, and if the concentration exceeds 150 ppm, an effect corresponding to the cost cannot be obtained. This concentration is more preferably 1.5 to 150 ppm.

The relative ratio (weight ratio) of a salt having a skin extension rate of less than 100% in a skin extension test and a plant-derived substance having a skin extension rate of less than 100% in a skin extension test in a preparation is as follows: The ratio is preferably from 600: 1 to 1: 1000, particularly preferably from 40: 1 to 1: 1000.

It is preferable that the above-mentioned salts and plant-derived substances are blended so that the skin extension rate of the entire bath composition in a skin extension test is less than 100%. And the bath agent composition of the present invention is p
The effect is more likely to be obtained when H exhibits a neutral to acidic region than when it shows alkaline.

Further, in addition to the above-mentioned essential components, salts other than the above-mentioned salts, fragrances, pigments, inorganic acids, organic acids and the like can be added to the bath agent composition of the present invention. Further, regarding the dosage form of the bath agent composition of the present invention,
Similar effects can be obtained in various dosage forms such as granules and tablets in addition to powders.
