Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to bath additives that can be added to bathtubs to enhance the effectiveness of bathing.

BACKGROUND OF THE INVENTION Various forms of bath additives are known.
There are bath additives that can be placed directly in the bathtub and dissolved, eliminating the need for cleaning up after use. Conventionally, water-soluble polymer materials used for packaging such bath additives include polyvinyl alcohol film (Japanese Patent Application Laid-Open No. 188813/1983), polyvinyl acetate partial oxide, polyvinyl alcohol partial butyrate, and vinylpyrrolidone-vinyl acetate film. Polymers (JP-A-50-126008) and the like are known.

However, these materials have drawbacks such as a slow dissolution rate in hot water of around 40° C., and the fact that they do not dissolve completely, resulting in residues adhering to the periphery of the bathtub and causing hot water stains.

The inventors of the present invention have made extensive studies to eliminate such drawbacks. As a result, they discovered that pullulan is a water-soluble polymer material suitable for this purpose, and that if the bath additive components were stored in a bag-like material made of pullulan, a bath additive with extremely excellent performance could be obtained. This led to the completion of the present invention.

Summary of the Invention The present invention provides a bag of pullulan or a water-soluble sheet made of pullulan, polyvinyl alcohol and/or polyvinylpyrrolidone, and a group consisting of a hot spring ingredient, a humectant, a bath oil, an extract of herbal medicine, a fragrance, and a coloring agent. The present invention provides a bath agent containing at least one component selected from the following. In the bath preparation of the present invention, at least a portion of the sheet constituting the bag-like article also contains at least one selected from the group consisting of hot spring ingredients, humectants, bath oils, herbal medicine extracts, fragrances, and colorants. Components may also be included.

Pullulan is Aureobasidium pullulans (, Au
Reobasidium pullulans) is a water-soluble polymer substance known as a polysaccharide consisting of neutral simple sugars produced outside the bacterial body, and dissolves quickly and completely in hot water.
It does not cause hot water stains, and has the effect of moisturizing the skin, stabilizing storage of other ingredients, and preventing fragrance from coming off.According to the present invention, the drawbacks of conventional water-soluble polymer materials can be overcome. A bath additive that exhibits excellent performance can be obtained.

The bath additives described in the detailed description of the invention are basically bags made of pullulan sheets containing various bath additives. In the present invention, in order to enhance the film-forming ability, one or both of polyvinyl alcohol and polyvinylpyrrolidone may be used together with pullulan. The amount of polyvinyl alcohol and polyvinylpyrrolidone is pullulan 1
The maximum amount is 50 parts by weight per 00 parts by weight, and if the amount is too large, the solubility may be decreased.

A sheet of pullulan or pullulan, polyvinyl alcohol and/or polyvinylpyrrolidone can be produced, for example, by appropriately casting an aqueous solution thereof and drying. The aqueous solution to be cast preferably has a solid content of about 40 to 70% by weight from the viewpoint of ease of operation and properties of the resulting bath additive, and drying can be carried out by a conventional method.

The thickness of the sheet obtained is not particularly limited, but
In terms of ease of handling, a thickness of about 5 to 150 μm is usually preferred.

Cut the obtained sheet to an appropriate size, for example, stack two rectangular sheets on three sides, or fold them in half and glue both sides to create a bag-like shape with one side not glued. You can get things. This adhesive can be moistened with water, starch glue,
This can be done using an adhesive such as polyvinyl alcohol glue or by thermocompression bonding. Note that a bag-like article may be obtained using a laminated sheet obtained by laminating a plurality of the above-mentioned sheets by a similar bonding method.

Examples of hot spring ingredients stored in the resulting bag-like material include sodium chloride, sodium hydrogen carbonate, sodium carbonate, saenohana, borax, boric acid, sodium sulfate, potassium sulfide, sodium sulfide, sodium sesquicarbonate, and oxidized Calcium, potassium nitrate, sodium nitrate, calcium nitrate, iron subsulfide, aluminum sulfate, metasilicic acid, silicic anhydride, neutral clay, magnesium carbonate, sodium thiosulfate, benzoic acid, sodium polyphosphate, potash soap, potassium carbonate, phosphoric acid Calcium hydrogen, sodium salicylate, potassium bromide, potassium chloride, ammonium chloride, iron sulfate, slaked lime, heavy magnesium carbonate, artificial Carlus salt, potassium permanganate, sodium phosphate, sodium hyposulfite, calcium thiosulfate, sodium hydroxide. ,
Examples include mica powder and sulfur, and these may be used alone or in combination of two or more.

Examples of humectants include glycerin, propylene glycol, sodium lactate, sodium pyrrolidone carboxylate, polyethylene glycol, carboxymethyl cellulose, dextrin, guar gum, quince seed gum, carrageenan, alginic acid, arabinogalactan gum, serine, chitosan, maltitol, Galactosamine, lactic acid bacteria culture, urea, Aqualyzer

Examples of bath oil components include lanolin, lanolin alcohol, stearyl alcohol, liquid halafine,
Examples include white petrolatum, casein, skim milk powder, ethanol, Nukaura, olive oil, soybean oil, etc., and they may be used alone or in combination of two or more.

Examples of herbal medicine extracts include sourdough, saffron, valerian, snail, staghorn, nebula, spruce, edulis, noyasmin, ginger powder, carrot, cinnamon bark, peony, heart leaf, scutellariae, saffron, valerian root, dokukatsu, calamus, and staghorn. , Japanese bean sprouts, Japanese bean sprouts, Japanese apricots, rice bran, saffron, sour oak, fennel, chimpi, candied leaves, bran bran, chamomile, peach leaf, Japanese radish, rosemary, Hypericum perforatum,
Examples include extracts obtained by conventional methods from Ebisu grass, honeysuckle, hops, etc., which may be used alone or in combination of two or more, and egg yolk powder and the like may also be used.

Examples of fragrances include dQ-menthol, Q-menthol, quince, d-camphor, d(1-camphor, turpentine oil, cypress oil, turpentine oil, cinnamon bark oil, bergamot oil,
Examples include iris pond, pineura, lavender oil, and cybernetic oil, which may be used alone or in combination of two or more.

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

These ingredients can be stored in a bag in the form of powder, granules, tablets, crystals, platelets, oil-containing capsules, etc., which can be obtained according to conventional methods. There are no particular limitations on the ingredients to be stored in the bag or the ratio of each ingredient when two or more are used together.

Furthermore, if desired, at least one of these components may be contained in at least a portion of the sheet forming the bag-like article. This can be done, for example, by adding the component to an aqueous solution of a water-soluble polymeric substance during the preparation of the sheet forming the bag-like material. Although the amount added is not particularly limited, the solid content of the aqueous solution is set to about 40 to 70% by weight, as described above, from the viewpoint of ease of operation.

The ingredients can be stored in the bag according to a conventional method such as filling from the non-adhesive part of the bag, and after filling, the non-adhesive part is glued using the same adhesive method as described above to form the desired shape. Obtain bath additives.

Note that the shape of the bag-like material is not limited to a rectangular shape, and various shapes can be adopted.Also, without forming the sheet into a bag-like material in advance, after placing the above-mentioned components on one sheet, other sheets can be placed. Methods such as covering the bag, gluing the surrounding area, and not cutting it can also be adopted, and in this specification, all of these methods are referred to as ``stored in a bag-like object''. Furthermore, as mentioned above, since pullulan itself has the effect of a bath agent, the sheet that forms the bag-like material and the sheet that contains each component are cut into small pieces and stored in the bag-like material along with the ingredients. You may let them.

When the bath preparation of the present invention is added to hot water in a bathtub during use, it dissolves quickly and completely without causing problems such as water stains. In addition, it is possible to suppress the release of fragrance during storage, and sufficiently release the fragrance when dissolved, and the dissolution ability does not give the unpleasant impression of ``too strong'' scent, which is different from that of conventional bath additives. It can also be prevented.

Next, the present invention will be explained in more detail with reference to Examples.
