Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a capsule bath preparation, and more specifically, to a capsule bath preparation that does not allow mold to grow or grow on its surface even in a hot and humid environment such as a bathroom. This invention relates to a capsule-shaped bath preparation with extremely excellent anti-mildew properties.

[Prior art] Bath preparations are often placed in bathrooms, where conditions such as high temperature and humidity are suitable for mold growth. This is likely to occur. Therefore, it is necessary to store it in a highly airtight container or in a low humidity place other than the bathroom to prevent moisture absorption, which is often inconvenient for actual use.

[Problem to be solved by the invention] For this reason, a method of preventing the growth of mold by incorporating antibacterial substances into the capsule coating is considered, but the commonly used methylparaben, propylparaben, geranyl acetate, and linalyl propionate When using antibacterial substances such as, when blended in an amount that provides a sufficient antifungal effect, there is a problem that the capsule coating becomes cloudy or colored due to crystal precipitation.

[Means for Solving the Problems] Under these circumstances, the present inventors conducted intensive research and found that the above problems were solved by incorporating a volatile antibacterial substance having an antifungal effect into the capsule contents. The present invention was completed based on this discovery.

That is, the present invention provides a capsule-shaped bath preparation containing a volatile antibacterial substance having an antifungal effect in the contents of a water-soluble capsule.

The capsule-shaped bath preparation in the present invention refers to one consisting of a capsule coating containing a water-soluble polymer as a main component and a content containing bath-side components. Here, the water-soluble polymer used in the present invention is not particularly limited, but for example, natural polymers include locust bean gum, xanthan gum, gelatin, etc., and semi-synthetic polymers include methylcellulose, carboxymethyl starch, alginate, etc. Examples of synthetic polymers include polyvinyl alcohol and polyethylene glycol.

Examples of volatile antibacterial substances having an antifungal effect that are incorporated into the contents of the capsule bath preparation of the present invention include 3.7-dimethyl-1,6-octarenin-3-ol, 3.7-dimethyl-1,6-octarenin-3-ol, and
Cymethyl-6-octen-3-ol, 3,7-cystyloctanol-3,2-trans-3,7-cystylate-2゜6-octadien-1-ol, 3,7-cymethyl-6-octen-1-ol, dimethyl Octatool, cis-3-hexenol, 2-isopropenyl-5-

-Lactones such as -decalactone, δ-undecalactone, δ-dodecalactone, and ε-dodecalactone can be mentioned. These can be used alone or in combination of two or more. In addition, its blending amount is 0 in the contents.
．． A range of 05 to 20% by weight, especially 05 to 5% by weight is preferred.

If it is less than 0.05% by weight, a sufficient antifungal effect cannot be obtained;
If it exceeds 0% by weight, the oil content will be too high, which is not preferable for practical use.

The contents of the capsule-shaped bath preparation of the present invention may be appropriately blended with ingredients commonly used in general bath preparations to the extent that their effects are not impaired. Such components include, for example, oil components such as triglycerides, hydrocarbon oils, ester oils, waxes, and higher alcohols; powder components such as coloring pigments, extender pigments, and pearl luster imparting agents; and various other salts, pigments, and vitamins. , hot spring active ingredients, seaweed extract, herbal medicine extract, pH
Conditioners, preservatives, antioxidants, chelating agents, humectants, beauty ingredients, etc. can be mentioned.

The method for producing the capsule bath preparation of the present invention is not particularly limited, but it can be produced according to the method for producing ordinary soft capsules. That is, for example, the capsule coating composition heated and melted is fed into a soft capsule manufacturing machine while being stretched into a sheet shape, deformed to fit a mold, and at the same time, the contents of the capsule are injected, and the capsule coating is cooled and solidified.

[Function] Since the capsule-shaped bath preparation of the present invention contains a volatile antibacterial substance having an antifungal effect in its contents, the antibacterial substance in its contents gradually penetrates into the capsule coating. death,
It is volatilized from the coating surface and exerts an anti-mildew effect on the capsule coating.

[Examples] Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited thereto.

(Manufacture of capsule bath preparation) Various capsule-shaped bath preparations were manufactured by the methods shown below.

Note that the amount of antibacterial substance is expressed in weight % based on the total composition of the capsule bath preparation.

Portions 1 to 4 and ratios o5 to 7: 10% by weight of polyoxyethylene (6) sorbitate tetraoleate, 15% by weight of polyoxyethylene (30) sorbitan trioleate, 30% by weight of propylene glycol dibucanate, shown in Table 1. An amount of antibacterial substance and an amount of liquid paraffin to make the total 100% were uniformly mixed and stirred to obtain capsule contents.

Separately, 30% by weight of glycerin and 70% by weight of gelatin were dissolved by heating to obtain a capsule coating composition. Next, this is fed into a soft capsule manufacturing machine while being stretched into a sheet shape, and at the same time it is deformed to fit the mold, the above capsule contents are injected, cooled and solidified, and an antibacterial substance is added to the contents.Contents 7.5g .

A capsule bath preparation having a coating of 1 g was obtained.

Ratios 1 to 4 and 8 to 10: The above except that no antibacterial substance is added in the production of the capsule contents, and the amount of antibacterial substance shown in Table 1 is added to the capsule coating component in place of the same amount of gelatin. In the same manner as above, a capsule bath preparation containing an antibacterial substance in the capsule coating was produced.

(Mold-proofing test) Aspergillus niger spores were inoculated onto the surface of the above capsule-shaped bath agent and left to stand at 25°C under high humidity. After 2 weeks, the presence or absence of mold growth on the capsule surface and the capsule coating. The appearance of the sample was visually observed and evaluated according to the following criteria, and the results are shown in Table 1.

Anti-mold effect: No mold growth was observed. ○No mold growth was observed. Capsule coating appearance: Transparent. ○Opaque due to coloring or cloudiness. As shown above, the capsule-shaped bath preparation of the present invention effectively prevents the generation and proliferation of mold on the surface of the capsule, and also has excellent aesthetic appearance because the capsule coating does not become colored or cloudy.

that's all
