The present invention relates to a novel bath agent composition that also allows the enjoyment of different fragrances.

[Conventional technology]

BACKGROUND ART - Various types of bath agent compositions are known that can be added to bathwater once a month.

Of the materials used as raw materials for these bath compositions, many of the volatile and delicious ingredients, such as perfumes, oils and fats, are volatilized during the preparation and filling process of the two-bath composition. Also,
These highly volatile components.

After filling the bath agent composition, as well as during its storage and use.

It only causes a decrease in ff1Elj due to volatilization (-
There are problems in that they attack the material of the container and, in addition, these components permeate outside the container. For this reason, the materials used as containers for packaging bath agent compositions are:

Due to special restrictions, we had no choice but to use materials that were also expensive.

Furthermore, with conventional bath salt compositions, the scent that can be enjoyed by using the bath salt composition twice is limited to one type of scent, either single or combined, and two or more different scents can be enjoyed in one use. There was nothing to enjoy in the bath.

[Problem that the invention seeks to solve]

The present invention suppresses the volatilization of highly volatile components during the manufacturing process and storage, and prevents the highly volatile components from corroding the material of the container.

Furthermore, as the raw materials for the bath agent composition of the present invention, in addition to those mentioned above, a wide range of other raw materials such as bactericidal preservatives, metal sequestrants, and others can be used as required.

Next, a method for manufacturing the bath agent composition of the present invention will be explained.

First, easily volatile bath agent ingredients such as the above-mentioned oils and fats and fragrances are coated with the above-mentioned film-form material 1, such as a natural or base water-soluble polymer substance, and a capsule is formed. As a means for this, general methods of encapsulation such as the spray lining method, the medium curing coating method, the coacervation process, and the submerged drying method can be used. The following is an example of obtaining a capsule by covering the cover.

As the film-form expropriated substance, 1 substance of 7 or 2 or more selected from natural or base water-soluble polymer substances!
~3j parts, preferably 22 to 32 parts, and 4t7~≦ of purified water
Add 2 parts to this and 10~) of glycerin! Part and sorbitol 2~! Add part.

Otsu! After stirring to dissolve and mix at ~25°C for 4t~♂ hours, preferably 5~2 hours, the mixture was degassed under reduced pressure at a pressure of 20-j OmrnH for j~♂ hours, and then the mixture was passed through a seamless capsule machine. Pour into coating agent supply tank.

Then-separately, seven or more readily volatile bath agent components are introduced into the fill supply tank as fill materials.

A seamless capsule machine (manufactured by Sankyo Kikai Seisakusho Co., Ltd.) uses equal amounts of these film-forming substances and easily volatile bath agent components.
From the nozzle of 8ANKYOCAP-CO TYPE), it is dripped into a coagulation liquid tank in which a coagulation liquid such as liquid paraffin is stored in advance. After separating the capsules thus formed in the coagulation liquid using filter paper, they are washed with ethanol and dried at room temperature, each particle having a diameter of about 3mm, a coating rate of about 30%, and a weight of about 2mm. ■Capsules were obtained.

Nao, the capsule coating obtained by the above-mentioned coating method is
Even if a natural or basic water-soluble polymer substance is used as a film-forming substance, depending on the coating method, it may not always be water-soluble (or it may be insoluble). When these capsules are placed in bath water and agitation or other physical means are applied, the coating is broken and the filling substance is dissolved in the bath water.

In the present invention, a readily volatile bath? What is the particle size of capsules in which the 'r'l component is coated with a film-form expropriation substance? θμ〜j
Approximately mm is appropriate.

The bath agent composition of the present invention is obtained by uniformly stirring and mixing the ivy capsules as described above with the above-mentioned solid bath agent raw materials.

In this case, the mixing ratio of capsules is 0.
．． Approximately 1 to 0% is appropriate.

In addition, the capsules are not limited to /fEi types (or, more than one type of capsules filled with different filling materials may be mixed together (or two or more types of capsules with different film thicknesses of coated expropriated substances may be mixed).

〔Effect of the invention〕

The bath agent composition of the present invention is made into capsules by coating easily volatile bath agent components with a film-forming substance, and the capsules are mixed with other bath agent raw materials, so it is different from the conventional powder form. Also, unlike solid bath agent compositions, easily volatile components do not volatilize during the manufacturing process or even when the product is stored.It has excellent stability over time. It eliminates various handling problems caused by volatilization of easily volatile ingredients during the preparation and filling process, and eliminates easily volatile ingredients such as fragrances even after filling the bath agent composition, during storage, and during use. (2) Also, there is no problem of easily volatile fractions such as fragrances permeating through the material of the container.

In addition, in the present invention, by using capsules with two or more different film thicknesses in the film forming process of the film-forming substance, it is possible to control the odor release, and furthermore, by using capsules with two or more different film thicknesses, By using capsules with different thickness and each containing a different fragrance,
- It is possible to enjoy two or more scents with one infusion of the bath agent composition, which is an effect that could not be obtained in conventional amounts.
