Description

  The present invention relates to a compression mold bath agent.

For bathing in the summer, it is required to suppress sweating after bathing and to obtain a refreshing feeling after bathing, and bath preparations containing a conventional aluminum salt and a cooling sensation agent have been reported (Patent Document 1). Moreover, a bath preparation containing a zinc compound has been reported as a technique for maintaining the refreshing feeling after bathing (Patent Document 2).
However, although the zinc compound has a high effect as described above, when it is added too much, sticking occurs when it is produced as a compression mold bath agent, and there is a problem that a good quality product cannot be produced.

As means for preventing sticking when producing a compression mold bath preparation containing a zinc compound, it is possible to reduce the amount of the zinc compound, reduce the pressure during compression molding, etc., but the former is effective. In the latter case, there is a problem that it collapses during transportation.
Accordingly, an object of the present invention is to provide a high-quality compression mold bath agent that has a refreshing feeling sufficiently after bathing, does not cause sticking during production, and does not collapse during transportation.

Therefore, the present inventor examined a means that does not cause sticking during production even when a large amount of a zinc compound is blended in a compression molding bath agent, and it is effective to blend a specific amount of a water-soluble polymer. I found.
That is, the present invention provides components (A) and (B),

  The compression mold bath agent of the present invention may be produced by mixing necessary components and directly compression molding by a tableting method or a roll press method. First, the component (A) and the component (B) are mixed. It is preferable to produce by compressing and molding the composition to be contained. Specifically, first, the water-soluble zinc compound as the component (A) and the above-mentioned components are selected as necessary, and a water-soluble polymer having a molecular weight of 1 million or less is further added as the component (B). After blending so that the total amount of component (A) and component (B) is 0.1 to 80% by mass with respect to 1 to 30 parts by weight, granulation is performed according to a conventional method as necessary. Then, it can be manufactured by compression molding. Specifically, the component (A), the component (B) and, if necessary, the component are granulated according to a conventional method. Granulation can be performed by extrusion granulation, rolling granulation, spray granulation, or the like, and may be either dry or wet. The weight average particle size of the obtained granulated particles is preferably 0.1 to 5 mm. Moreover, it can manufacture by selecting the said arbitrary component to the obtained granulated particle as needed, and compression-molding after mixing | blending.

Examples 1 to 4 and Comparative Examples 1 to 5
With respect to the composition shown in Table 1, 100 tablets of 50 g were continuously compressed and evaluated for sticking. A normal rotary type tableting machine was used as the compression molding machine. In addition, the 50 g tablets produced were put into a bath of 150 L at 40 ° C., and 10 female panelists evaluated the refreshing feeling after 5 minutes of bathing.

Examples 5-7
For Examples 5-7 of the compositions shown in Table 1, after mixing at a ratio of 3 parts by weight of polyethylene glycol 6000 with respect sulfo carbolic zinc 1 part by weight, subjected to extrusion granulation, a particle size of 1~3mm particles Manufactured. After mixing other components with 4 parts by weight of the granulated product, it was molded in the same manner as described above using an ordinary rotary tableting machine. Evaluation was also performed in the same manner as described above.

[Evaluation criteria for sticking]
4: No sticking at all 3: Slight adhesion on the wrinkle surface but smooth tablet surface 2: Slight adhesion on the tablet surface 1: Remarkable adhesion on the tablet surface

[Evaluation criteria for refreshing feeling]
4: Very refreshing 3: Refreshing 2: Slightly refreshing 1: Not refreshing

  As a result, as shown in Table 1, with respect to the compression mold bath agent in which the component (A) and the component (B) are blended within the scope of the present invention, sticking does not occur at all, and the evaluation of the refreshing feeling and the sustained effect is also possible. It was good. On the other hand, when the blending amount of the component (A) and the component (B) is outside the range of the present invention, there is no problem with sticking when the component (A) is small, but the effect of the refreshing feeling is low, and the component ( When the weight of (B) is less than 1 with respect to A), even if the component (A) is sufficiently effective, sticking occurs, so that a high-quality compression mold bath agent cannot be produced. I understood that.
