Description

Description: TECHNICAL FIELD The present invention relates to a bath preparation composition having a high antiperspirant effect. 2. Description of the Related Art In summer bathing, it is required to suppress perspiration after bathing and obtain a refreshing feeling after bathing. Conventionally, bathing agents containing water-insoluble inorganic powder have been used. . [0003] However, when the water-insoluble inorganic powder is used, there are drawbacks such as the bath water becomes cloudy and the bottom of the bath tub becomes rough. Accordingly, there has been a demand for a bath agent which does not have these disadvantages and can provide a refreshing feeling. [0004] Under such circumstances, the present inventors have conducted intensive studies. As a result, when an aluminum salt and a cooling sensation agent are used in combination, the antiperspirant effect is high, and a refreshing feeling is obtained. The present inventors have found that a bath agent that can be applied is obtained, and have completed the present invention. That is, the present invention provides a bath preparation composition containing an aluminum salt and a cooling sensation agent. The aluminum salt used in the present invention includes, for example, inorganic aluminum salts such as aluminum sulfate, potassium aluminum sulfate, ammonium ammonium sulfate and aluminum chloride; soluble aluminum carboxylate salts such as aluminum lactate, aluminum citrate and aluminum malate And the like.

It is preferable to mix 5 to 1%, and the concentration in bath water is 0.03 to 10 ppm, particularly 0.1 to 10 ppm.
It is preferable that the concentration is 3 to 8 ppm, more preferably 0.5 to 5 ppm. In addition, by adding a carbonate to the bath additive composition of the present invention in addition to the aluminum salt and the cooling sensation agent, the refreshing feeling can be further enhanced. The carbonate used here includes, for example, sodium carbonate, potassium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate, sodium sesquicarbonate and the like, and particularly preferable are sodium carbonate and sodium hydrogencarbonate. These carbonates are preferably incorporated in the entire composition in an amount of 10 to 98%, particularly 30 to 90%, and the concentration in the bath water is preferably 10 to 400 ppm, particularly preferably 30 to 400 ppm. In this case, the pH of the bath additive composition of the present invention is preferably 7 to 10, particularly 7 to 9, and more preferably 8 to 9 when made into a 0.01% aqueous solution (40 ° C.). . pH 7
If it is less than 10%, the abundance ratio of bicarbonate ion [HCO ₃ ⁻ ] and carbonate ion [CO ₃ ²⁻ ] is small and a sufficient feeling of refreshment cannot be obtained. Absent. In the present invention, the pH was measured as follows. That is, immediately before the measurement, 5 l of standard water is prepared in a 5 l beaker at 40 ° C. 0.5g to this
And dissolve (0.01%). In the case of tablets, after crushing to an appropriate size using a mortar, a lump of about 0.3 to 0.5 g is selected and precisely weighed, and standard water is weighed to a concentration of 0.01% in a 5 l beaker. Take and dissolve the sample. Immediately after the dissolution is completed, the hot water is mixed so as to be uniform, and the pH is measured by the general test method of the Japanese Pharmacopoeia. The standard water was prepared by adding calcium chloride dihydrate to 5 l of ion exchange distilled water. 36 mg, and then 83.83 mg of sodium bicarbonate are dissolved. Immediately after the sodium bicarbonate is dissolved, carbon dioxide gas is blown in to adjust the pH to 7.0. Further, in addition to the above-mentioned components, other general-purpose raw materials used for ordinary bath additives can be used in the bath agent composition of the present invention. Examples of such general-purpose raw materials include inorganic acids such as boric acid, metasilicic acid, and silicic acid; organic acids such as benzoic acid, citric acid, fumaric acid, succinic acid, tartaric acid, pyrrolidonecarboxylic acid, adipic acid, and salicylic acid; sodium chloride , Sodium sulfate, sodium nitrate, potassium chloride, sodium polyphosphate and other inorganic salts;

Can be blended. The bath preparation composition of the present invention can be produced according to a usual method, and can be in various forms such as powders, granules, tablets and the like. The bath preparation composition of the present invention has a high antiperspirant effect and can give a refreshing feeling. Next, the present invention will be further described with reference to examples, but the present invention is not limited to these examples. Example 1 A bath preparation composition having the composition shown in Table 2 was produced by a conventional method, and the antiperspirant rate and the refreshing feeling after bathing were evaluated. (Evaluation method) Antiperspirant rate: An evaluation sample solution (40 ° C., 0.
The forearm is partially immersed in a 5% (01% solution) for 10 minutes, dried with a towel and dried, and then a 5% iodine-alcohol solution is applied to the test site and dried. The starch slide is fixed to the examination site, and the subject is placed in a room at 40 ° C. and a relative humidity of 40%, and forced to sweat for 10 minutes. The number of sweat glands per fixed area (3.14 cm ² ) of the colored slide is measured, and the antiperspirant rate is calculated by the following equation. In addition, the hot water was used for the control site. Table 2 shows the results. ## EQU1 ## Refreshing feeling after bathing: (1) Using 10 panelists, refreshing feeling after bathing in a partial bath was examined. 28 ° C
