Description

The present invention provides a liquid agent for immersion, which is a xyloglucan-containing gel composition molded into a desired shape, capable of suppressing its shape loss and disintegration due to dissolution, and maintaining the desired shape until just before opening. Regarding.

Xyloglucan has the characteristics of forming a gel-like composition with konjac-like elasticity and self-shape retention when combined with a specific component. Taking advantage of this feature, self-shape-retaining gel cleansers and gel cosmetics are known, for example, as shown in Patent Document 1 and Patent Document 2, and furthermore, in Patent Document 3, It is known for use as a cooling sheet for cooling during fever and inflammation as indicated.

However, it is known that a self-retaining xyloglucan-containing gel composition tends to lose its shape even after being molded into a desired shape using an arbitrary mold. For example, when the xyloglucan-containing gel composition is placed on a flat surface or an arbitrary uneven surface and stored after being removed from the mold, there is a problem that the xyloglucan-containing gel composition deforms along the contact surface.

Therefore, as a method of distributing the xyloglucan-containing gel composition to the market, a method of distributing it in a state where it is poured into a jelly cup container, or a method of encapsulating it in a mold such as a rubber balloon as shown in Patent Document 4. A method of distributing it while maintaining its shape is adopted by molding it, distributing it as it is, and taking it out at the user's hand.

However, the xyloglucan-containing gel composition molded into the desired shape is removed from the mold without the need for a support (or support material) for retaining the shape of the gel, such as a gel-forming vessel. A method for preventing deformation and stably maintaining the shape was not known.

In order to evaluate the stability of the xyloglucan gel composition, a xyloglucan-containing gel composition was prepared according to the composition shown in "Table 01". The preparation method is as follows. Components 1 to 3 are dispersed at 40 to 60° C., added to component 4 heated to 50 to 60° C., and dissolved with stirring (dissolved solution 1). After components 5 to 7 are uniformly mixed in the same container, the mixture is heated to 55° C. to 60° C., added to solution 1 with stirring, and mixed until uniform (preparation solution 1). The prepared liquid 1 thus obtained is poured into a mold before it cools down, and left to cool. After leaving it for 24 hours, it is removed from the mold to obtain a xyloglucan-containing gel detergent molded into a desired shape.

The xyloglucan-containing gel cleanser obtained in "Table 01" was removed from the mold, placed in a mold having a different shape, and allowed to stand still for 24 hours. The xyloglucan-containing gel-like composition did not maintain the shape of the initial mold and was out of shape (Comparative Example 1).

For the evaluation of the liquid agent in which the xyloglucan-containing gel composition is immersed, each liquid agent (hereinafter referred to as a storage solution) was mixed and prepared according to the compositions shown in "Table 02", "Table 03" and "Table 04". The xyloglucan-containing gel detergent prepared according to the composition described in "Table 01" was immersed in each storage solution, and the state after immersion for 24 hours was confirmed. The results are shown in the following table.

A xyloglucan-containing gel detergent having the composition shown in "Table 05" was prepared and immersed in the storage solution of Example 11 shown in "Table 03" (Example 18). As shown in "Table 05", xyloglucan-containing gel compositions of three different colors using water-insoluble coloring components were formulated so as to have different specific gravities. Appropriate amounts were poured into a mold in descending order of specific gravity, left at rest for 24 hours, removed from the mold, immersed in the storage solution of Example 11, and stored at room temperature. The state after more than one year is shown in "Fig. 1". Even if the storage period after immersion was 1 year or more, the storage solution was transparent, and the xyloglucan-containing gel composition was stably maintained without any disintegration or elution of the coloring component used.
