Description

Description: FIELD OF THE INVENTION The present invention relates to a capsule-type bath preparation, and more specifically, does not generate or proliferate mold on its surface even in a high-temperature and high-humidity environment such as a bathroom. The present invention relates to a capsule-like bath agent having extremely excellent antifungal properties.

[Prior art] Bath agents are often placed in a bathroom with conditions suitable for the growth of mold, which is hot and humid. In particular, in the case of a capsule-like bath agent, the gelatin of the capsule coating is rich in hygroscopicity, so that mold is particularly resistant to mold. It is easy to occur. For this reason, it is necessary to store in a highly airtight container or store in a low humidity place other than the bathroom to prevent moisture absorption, which is often inconvenient for actual use.

[Problems to be Solved by the Invention] For this reason, a method for preventing the occurrence of mold by mixing an antibacterial substance into the capsule coating is considered. However, methylparaben, propylparaben, geranyl acetate, and linalylpropionate which are usually used are considered. When an antibacterial substance such as the above is used, there is a problem that if the amount is sufficient to obtain a sufficient antifungal effect, the capsule coating becomes cloudy or colored due to crystallization.

[Means for Solving the Problems] Under such circumstances, the present inventors have conducted intensive studies and as a result, the above problems were solved by incorporating a volatile antibacterial substance having a fungicidal action into the contents of the capsule. The present invention has been completed.

That is, the present invention provides a capsule-like bath agent comprising a volatile antibacterial substance having a fungicidal action in the contents of a water-soluble capsule.

The capsule-like bath agent in the present invention refers to a product comprising a capsule coating mainly composed of a water-soluble polymer and a content containing a bath agent component. Here, the water-soluble polymer used in the present invention is not particularly limited,
For example, natural polymers include locust bean gum, xanthan gum, gelatin and the like, semi-synthetic polymers include methyl cellulose, carboxymethyl starch, alginate and the like, and synthetic polymers include polyvinyl alcohol and polyethylene glycol.

Examples of the volatile antibacterial substance having a fungicidal effect incorporated in the contents of the capsule bath composition of the present invention include 3,7-dimethyl-1,6-octadien-3-ol and 3,7-dimethyl-6. -Octen-3-ol, 3,7-dimethyloctanol-3, 2-trans-3,7-dimethyl-2,6-octadien-1-ol, 3,7-dimethyl-6-octen-1-ol, Dimethyloctanol, cis-3-hexenol, 2-isopropenyl-5-methylhexene-

Lactones such as dodecalactone are exemplified. These can be used alone or in combination of two or more. Further, the compounding amount is preferably in the range of 0.05 to 20% by weight, particularly 0.5 to 5% by weight in the content. 0.05% by weight
When the amount is less than 20%, a sufficient antifungal effect cannot be obtained.

To the contents of the capsule-shaped bath preparation of the present invention, components usually used in general bath preparations are appropriately blended as long as the effects are not impaired. Examples of such components include oil components such as triglycerides, hydrocarbon oils, ester oils, waxes, and higher alcohols; powder components such as coloring pigments, extender pigments, and pearlescent agents; and other various salts, pigments, and vitamins. , Hot spring active ingredients, seaweed extract, herbal extract, pH
Modifiers, preservatives, antioxidants, chelating agents, humectants, cosmetic ingredients and the like.

Although the method for producing the capsule-like bath agent of the present invention is not particularly limited, it can be produced according to the usual method for producing soft capsules. That is, for example, the composition for capsule coating which is heated and melted is fed into a soft capsule manufacturing machine while being stretched into a sheet shape, deformed according to a mold, and at the same time, the capsule content is injected, followed by cooling and solidification.

[Action] Since the capsule-shaped bath preparation of the present invention contains a volatile antibacterial substance having a fungicidal action in the contents,
The antibacterial substance in the contents gradually penetrates into the capsule coating, volatilizes from the coating surface, and exhibits an antifungal effect in the capsule coating.

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

(Production of Capsule Bath Agent) Various capsule bath agents were produced by the following methods. The amount of the antibacterial substance is% by weight based on the total composition of the capsule-shaped bath preparation.

Inventive products 1-4 and comparative products 5-7: 10% by weight of polyoxyethylene (6) sorbite tetraoleate, 15% by weight of polyoxyethylene (30) sorbitan trioleate, propylene glycol didecanoate
30% by weight, the amount of antibacterial substance shown in Table 1 and 100%
Of liquid paraffin was 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 composition for capsule coating. Next, this is fed into a soft capsule manufacturing machine while being stretched in a sheet shape, deformed according to a mold and simultaneously injected with the contents of the capsule, cooled and solidified and mixed with an antibacterial substance 7.5 g of the content, 1 g of a capsule-like bath agent was obtained.

Comparative products 1 to 4 and 8 to 10: The same as above except that an antibacterial substance was added in the production of the capsule contents, and the amount of the antibacterial substance shown in Table 1 was added to the capsule coating component instead of the same amount of gelatin. Similarly, a capsule-like bath agent in which an antibacterial substance was blended in a capsule coating was produced.

(Antifungal test) Aspergillus niger spores were inoculated on the surface of the above-mentioned capsule bath, allowed to stand at 25 ° C under high humidity, and after 2 weeks, the presence or absence of mold on the capsule surface and the presence of a capsule coating were observed. The appearance was visually observed and evaluated according to the following criteria.

Antifungal effect: No mold was observed. ○ Mold was observed. × Capsule coating appearance: Transparent. ○ Transparency due to coloring or cloudiness. × [Effects of the Invention] As described above, the capsule-form bath agent of the present invention effectively prevents the generation and growth of mold on the capsule surface, and is excellent in appearance because the capsule coating is not colored or clouded. is there.
