The coating amount of the wax component is preferably 0.1 to 15% by mass in 100% by mass of the sheet bath. If it is less than 0.1% by mass, uniform coating may not be possible. If it exceeds 15% by mass, sufficient dissolution may not be possible. The coating amount is more preferably 1 to 5% by mass from the economical aspect.

The sheet-like bath agent of the present invention preferably has an embossed surface. When the surface is embossed, an air layer is formed in the surface irregularities when placed in water. Thereby, when it puts in water, it can float suitably in bath water. In addition, it can be prevented from adhering to each other during storage and becoming a lump. It does not specifically limit as a method of embossing, A well-known method can be mentioned.

The method for producing the sheet-like bathing agent of the present invention is not particularly limited, for example, after uniformly mixing the bathing agent blend in which the above-described components are mixed with a stirrer, the sheet-like bathing agent is molded with a certain thickness, The method obtained by making it dry can be mentioned. The sheet bath of the present invention may be embossed when formed into a sheet or embossed in a later step. Moreover, after drying the sheet-like bath agent of this invention, you may coat the surface of the said sheet | seat with a wax component. Moreover, you may laminate | stack these as needed. The drying is preferably performed at 70 to 160 ° C. for 5 to 30 minutes.

The sheet bath of the present invention can be easily formed into an arbitrary shape by a known method such as sheet punching. For example, as shown in FIG. You can enjoy watching the melting process, such as when the petals dissociate and dissolve from the base of the petals. In addition, the pattern of FIG. 1 represents the state of embossing.

In addition, by treating only a part of the surface with the wax component, the dissolution rate of the sheet bath can be adjusted, and the change in form upon dissolution can be controlled. For example, as shown in FIG. 2, there is a method in which the component is applied only to a portion other than the root portion of the petal of the flower-shaped sheet. In the sheet bath of FIG. 2, the root portion of the petal to which the wax component has not been applied is first dissolved, and then the portion to which the wax component has been applied dissolves due to the temperature rise caused by hot water. As a result, as shown in FIG. 3, it is possible to enjoy a melting state in which the flower shape becomes petals and dissolves.

The sheet bath of the present invention can also be used in combination with other solid bath components. The sheet-like bath agent of the present invention and the other solid bath agent components may be enclosed. Such a bath agent composition is also one aspect of the present invention.
The other solid bath component is not particularly limited, and examples thereof include inorganic salts, vitamins, rice germ oil, rice fermented extract, dipotassium glycyrrhizinate, chimpan powder, ginseng powder, senkyu, shobu, toki, chamomile. The thing which consists of an ingredient generally used as a bath agent containing active ingredients, such as these, can be mentioned. Examples of the form of the other solid bath agent component include powder, granules or tablets.
The sheet-like bathing agent of the present invention and the other solid bathing agent components may be enclosed by a well-known packaging method using an aluminum pouch or the like.

The sheet bath of the present invention can be integrated with a solid foam bath tablet. For example, when producing a solid foamed bath salt tablet, the sheet-like bath agent of the present invention can be placed on the tableting surface and compressed by tableting pressure to be integrated. In the case of integration, one or a plurality of the sheet baths of the present invention may be applied, or may be applied to one side or both sides of the tablet. Such a bath agent composition is also one aspect of the present invention.

The sheet-like bathing agent of the present invention is made of a water-soluble polymer, and has a flaky shape that has never been present, with a thickness of 200 μm or less. Furthermore, it is excellent in playability and visibility when floated on bath water.

Since the sheet-like bathing agent of the present invention has the above-described configuration, it can float suitably in bath water and is excellent in playability and visibility. For this reason, it is suitably applied as a floating bath agent. Moreover, it can also be used in combination with a well-known bath agent.

Then, it was punched into the flower shape of FIG. 1 and the heart shape of FIG. 4 and dried to obtain a sheet-like bathing agent having a thickness of 55 μm (1-a). The entire surface was coated with a 10% by mass shellac alcohol solution with respect to 100% by mass of the bath agent to obtain a sheet-like bath agent having a thickness of 60 μm (1-b). The water content of the obtained sheet-like bath agent was 5.19% by mass for A, and 7.45% by mass for B and C.

(Example 2)
As shown in FIG. 2, a sheet bath was obtained in the same manner as in Example 1 except that only the part other than the petal root part of the flower-shaped sheet was coated with shellac (supra).

(Evaluation of solubility)
The obtained bath agent was dropped on the surface of hot water at 40 ° C. The sheet-like bathing agent of Example 1 floated while maintaining its shape on the surface of hot water, and 1-a slowly dissolved over a period of about 5 to 15 minutes and 1-b over a period of about 15 to 30 minutes. . Moreover, after the base part of a petal melt | dissolves in about 1 to 2 minutes, the sheet-like bath agent of Example 2 floats on the surface of hot water, and becomes a petal shape like FIG. It slowly dissolved over a period of about minutes.

(Example 3)
0.5 g of the sheet bath obtained in Example 1 and 25 g of a commercially available powder bath were mixed and sealed in an aluminum pouch. After storage for 6 months at 40 ° C. and 75% humidity, the product was opened and the mixture was placed in 40 ° C. hot water in a 200 L bath. The powdered bathing agent dissolved instantly and uniformly, and the sheet bathing agent floated while maintaining the shape on the surface of the hot water, and slowly dissolved over a period of about 5 to 15 minutes.
