Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to bath agent compositions, and in particular to easily volatile bath f! F
In addition to increasing the storage stability for IJg, you can enjoy the change in the dissolution color of the bath water, and as the film-forming substance dissolves, the fragrance, etc. coated with the film-forming shed dissolves in the bath water. The present invention relates to a novel bath agent composition that allows the user to enjoy the change in the scent of bath water.

[Conventional technology]

Conventionally, various bath agent compositions have been proposed to be added to bath water. And these bath salts Mi fi
Many of the same highly volatile components used as raw materials for bath preparations, such as perfumes, oils and fats, volatilize during the preparation and filling process of bath compositions.

In addition, these highly volatile components do not only cause a decrease in concentration due to volatilization after filling the bath agent composition, but also during its storage and use. There are problems such as a portion of the liquid permeating outside the container.For this reason, there are special restrictions on the material used for packaging containers for bath agent compositions, and it is necessary to use materials that are cost-effective. In addition, with conventional bath agent compositions, the fragrance that can be enjoyed by using the bath agent composition twice is limited to one type of fragrance, either single or combined, and two or more types of fragrance can be enjoyed. There is nothing that allows you to enjoy different scents in one bath.

Furthermore, in Ichijomai's bath agent compositions, the pigments used are generally stirred and mixed uniformly into the composition during one bath, and the color of the dissolved pigment in the bath water changes during bathing. ,
There was nothing that could make bathing more enjoyable.

[Problem that the invention seeks to solve]

The present invention solves the problems of suppressing the volatilization of highly volatile components during manufacturing processes and storage, and preventing highly volatile fractions from corroding the material of the container and permeating outside the container. You can enjoy the change in color tone of your bath water by using the bath salt composition twice.

In addition, it was an attempt to provide a bath additive composition that did not exist in Jubeichen, which also allowed the user to enjoy the change in the scent of the bath water.

It is also possible to mix two or more types of capsules with different dissolution times, such as mixing with soft capsules using gelatin.
Furthermore, two or more kinds of capsules having different thicknesses of film-forming substances may be mixed.

〔Effect of the invention〕

The bath agent composition of the present invention is prepared by coating easily volatile bath agent components with a water-soluble film-forming substance to which a dye has been added to form capsules, and then mixing the capsules with other bath agent raw materials. Therefore, unlike conventional powder or solid bath agent compositions, easily volatile components do not volatilize during the manufacturing process or when the product is stored ((), and it has excellent stability over time. For this reason, various handling problems due to volatilization of easily volatile fractions during the preparation and filling process of bath agent m acids are eliminated, and even after filling the bath agent composition, during storage and use. The concentration of easily volatile ingredients such as fragrances does not decrease (and there is no problem such as easily volatile ingredients such as fragrances permeating through the material of the container).

Furthermore, when the bath agent composition of the present invention is used by dissolving it in bath water, the pigment added in advance to the water-soluble film-forming substance dissolves in the bath water. This invention allows you to enjoy the changing color of the bath water while taking a sea urchin bath.

Furthermore, in the bath agent composition of the present invention, the formation of a water-soluble film to which one dye is added is made possible by the addition of one or more substances with different film thicknesses in the process of forming a film of one substance. Furthermore, in the bath agent composition of the present invention, the capsule itself is colored by adding a pigment to the substance for forming a water bath i-film. , It is also possible to strongly impress (impress) the efficacy of the bath on the bathers.

Here, we will compare the dissolved color tone and fragrance residual rate of the bath agent composition of the present invention and a conventional bath agent composition (uniformly mixed with easily volatile raw materials such as pigments and fragrances). As shown, it is of first order.
