Description

Description: FIELD OF THE INVENTION The present invention relates to a bath agent that is added to hot water in a bath to enhance bathing effect.

BACKGROUND OF THE INVENTION Various forms of bath agents are known, one of which is to package one dose of bath agent with a water-soluble polymer material,
There is a bath agent that can be placed in a bath as it is and dissolved to eliminate the need for cleaning up after use. As a water-soluble polymer material used for packaging such a bath agent, there have hitherto been used polyvinyl alcohol membranes (JP-A-58-188813), polyvinyl acetate partial oxides, polyvinyl alcohol partial butyrate, vinylpyrrolidone-vinyl acetate copolymers. Polymer (Japanese Patent Laid-Open No. 50
-126008) is known.

However, these materials have drawbacks such as a low dissolution rate in hot water of about 40 ° C., incomplete melting, and residue sticking to the periphery of the bath, causing hot water stains.

The present inventors have earnestly studied in order to eliminate such a defect. As a result, it was found that pullulan is a water-soluble polymer material suitable for this purpose, and when the bath agent component is stored in a bag-shaped product formed from the sheet, a bath agent exhibiting extremely excellent performance is obtained. The present invention has been completed.

SUMMARY OF THE INVENTION The present invention is a bag of water-soluble sheet consisting of pullulan or pullulan and polyvinylpyrrolidone, a hot spring component,
The present invention provides a bath preparation containing at least one component selected from the group consisting of a moisturizing agent and a herbal extract. In the bath agent of the present invention, at least a part of the sheet constituting the bag-like material has at least one component selected from the group consisting of hot spring ingredients, moisturizers, bath oils, herbal extract, flavors and colorants. May be contained, and a similar sheet containing such components may be put in a bag.

Pullulan is Aureobasidium pullulans (Aureob
asidium pullulans) is a water-soluble high-molecular substance known as a polysaccharide consisting of neutral simple sugars produced outside the cells. It dissolves quickly and completely in warm water and does not cause hot water stains. , Has a skin moisturizing action, has a stabilizing action on the preservation of other components, and has a preventive action against fragrances, etc.
It is possible to obtain a bath agent exhibiting excellent performance by eliminating the drawbacks of conventional water-soluble polymer materials.

DETAILED DESCRIPTION OF THE INVENTION The bath agent of the present invention is basically a bag-like material formed of a pullulan sheet and containing various bath agents. In the present invention, polyvinyl pyrrolidone may be used in combination with pullulan in order to enhance the film forming ability. The amount of polyvinylpyrrolidone is up to 50 parts by weight with respect to 100 parts by weight of pullulan, and if the amount is too large, the solubility will decrease.

The sheet of pullulan or pullulan and polyvinylpyrrolidone can be produced, for example, by appropriately casting their water solubility and drying. Due to the ease of work and the properties of the resulting bath agent, the aqueous solution to be cast has a solid content of 40%.
Approximately 70% by weight is preferable, and drying can be performed by an ordinary method. The thickness of the obtained sheet is not particularly limited, but usually 5 to 150 from the viewpoint of easy handling.
A thickness of about μ is preferable.

The obtained sheet is cut into an appropriate size, and, for example, two square sheets are stacked and folded on three sides or folded in two, and if both side portions are adhered, one side is a non-adhesive bag-like shape. The thing is obtained. This bond can be moistened with water, starch glue,
This can be done by using an adhesive such as polyvinyl alcohol glue or by thermocompression bonding. In addition, you may obtain a bag-shaped article using the laminated sheet which laminated | stacked the said sheet | seat multiple sheets by the same bonding method.

Examples of hot spring components to be stored in the obtained bag-like material are sodium chloride, sodium hydrogen carbonate, sodium carbonate, hot water, borax, boric acid, sodium sulfate, potassium sulfide, sodium sulfide, sodium sesquicarbonate, calcium oxide, Potassium nitrate, sodium nitrate, calcium nitrate, iron phosphite, aluminum sulfate, metasilicic acid, silicic acid anhydride, neutral clay, magnesium carbonate, sodium thiosulfate, benzoic acid, sodium polyphosphate, potassium soap, potassium carbonate, calcium hydrogen phosphate , Sodium salicylate, potassium bromide, potassium chloride, ammonium chloride,
Examples thereof include iron sulfate, slaked lime, heavy magnesium carbonate, artificial Callus salt, potassium permanganate, sodium phosphate, sodium hypophosphite, calcium thiosulfate, sodium hydroxide, mica powder, and sulfur.
You may use together 1 or more types.

Obtained from common methods, such as, butterbur, juniper, juvenile, deer, rice bran, saffron, sardine, fennel, chimpi, citrus powder, rice bran, chamomile, peach leaf, yochinin, rosemary, Hypericum perforatum, Ebisugusa, honeysuckle, hops, etc. Examples of the extract include an extract, a combination of two or more kinds, and an egg yolk powder or the like.

Examples of flavors are dl-menthol, l-menthol,
Peppermint oil, d-camphor, dl-camphor, turpentine oil,
Hinoki oil, orange peel oil, cinnamon oil, bergamot oil, iris oil, pine oil, lavender oil, Borneolum, etc. may be mentioned, and they may be used alone or in combination of two or more kinds.

Examples of colorants include Blue No. 1, Blue No. 2, Yellow No. 4,
Yellow No. 202 (1), green No. 204, etc. may be mentioned alone or in combination of two or more kinds.

These components can be stored in a bag-like product in the form of powder, granules, tablets, crystals, plates, oil-containing capsules and the like obtained by a conventional method. The amount of the components to be stored in the bag-like material and the ratio of each component when two or more types are used together are not particularly limited.

Further, if desired, at least one of these components may be contained in at least a part of the sheet forming the bag. This can be performed, for example, by adding the component to an aqueous solution of a water-soluble polymer substance at the time of preparing a sheet for forming a bag-shaped material. The addition amount is also not particularly limited, but the solid content of the aqueous solution is set to about 40 to 70% by weight, as described above, from the viewpoint of workability and the like.

The components can be stored in the bag-like material according to a conventional method such as filling from the non-adhesive portion of the bag-like material. Obtain a bath agent.

The shape of the bag-like object is not limited to a quadrangle, and various shapes can be adopted. Further, after the above components are placed on one sheet without forming the sheet in the bag-like object in advance, another sheet is A method of covering, surrounding and adhering the periphery can also be adopted, and in the present specification, all of these are referred to as a state of being "stored in a bag". Further, as described above, since pullulan itself has the effect of a bath agent, the sheet forming a bag or the sheet itself containing each component is cut into small pieces and stored in the bag together with the above components. You may let me.

When the bath agent of the present invention is added to the hot water of the bath upon use, there is no problem that it quickly and completely melts to form red hot water. In addition, it can suppress the emission of perfume during storage, sufficiently release the scent when dissolved, and also give a nasty impression with conventional bath agents such as "too strong scent" before dissolution. Can be prevented.

Next, the present invention will be described in more detail with reference to examples.

Example 1 40 g of pullulan is mixed well with 60 g of water, dissolved, cast on a polyethylene terephthalate plate and dried at room temperature to obtain a sheet having a thickness of about 20μ. This is cut into a 7 cm × 20 cm square, folded in two at the center of the long side, and the two side parts are thermocompressed to obtain a bag-shaped product with one side not bonded.

To 100 g of dried peach leaves, 600 g of ethanol is added, and the mixture is extracted by heating at 80 ° C to obtain 400 g of an extract. Cool to room temperature and over. After cooling to 0-5 ° C overnight, repeat. This extract 50
