Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention provides a method for dissolving water in running water (hot water, cold water) in a shower device when using a shower.
The present invention relates to a solid shower product that provides a cooling sensation, beauty effects, cleaning effects, etc. to the whole body. [Prior art] Conventionally, when using a bathtub for bathing, it is possible to obtain various efficacy effects, a refreshing feeling, etc. to the whole body by adding bath additives, bath oil, bath salts, etc. to the bath water. . However, with bath products that can be used when showering, the bather applies or sprays the product on his or her own body and then showers with running water (hot or cold water) from the shower, and the effect of the product is felt on the whole body. It is difficult to obtain such information because some parts are out of reach. Furthermore, since the product is washed away by running water, it is not sustainable over time. The product is dissolved in the shower device, and the color, scent, cleaning agent, etc. are removed by running water (warm water,
Various shower devices have been devised for the purpose of spraying water mixed with cold water.

39610, Utility Model Publication No. 54-148666). However, ordinary powder used by adding it to bath water,
When a solid or liquid product is put into a shower device, its color, fragrance, cleaning agent ingredients, etc. dissolve in a short period of time, eject, and return to the original flowing water, making it unsustainable. That is, if the dosage form of the product is liquid, it will flow instantly within the shower device. Furthermore, even in the case of powder, the dissolution time is short and there is no sustainability. Furthermore, in the case of tablets, they are generally made by adding a binder to powder and compressing it, and the dissolution time is short.
There is no sustainability. [Problems to be solved by the invention] As mentioned above, ordinary powder, solid, and liquid products that are added to bath water and used in shower equipment do not last long. It is therefore desirable to have a solid shower product that lasts for a long time, and the present invention solves this problem. [Means for Solving the Problem] In view of the above circumstances, the present inventors have completed the present invention as a result of various studies to obtain a long-lasting solid shower product free of the above-mentioned drawbacks. I came to the conclusion. That is, the present invention provides dyes, fragrances, bath agent raw ingredients,
This is a solid shower product characterized by containing about 30 to 95% by weight of polyethylene glycol along with one or more components selected from detergent raw materials, cosmetic raw materials, etc. The present invention will be explained in detail below. Polyethylene glycol used in the present invention can be produced according to conventional methods. For example, it can be produced by adding ethylene oxide to ethylene glycol, and in this case, a series of polyethylene glycols with different molecular weights can be produced depending on the amount of ethylene oxide added. Its synthetic route and chemical structure are represented by the following general formula. [In the formula, n is an integer] The polyethylene glycol used in the present invention preferably has an average molecular weight of 1000 to 6000. Alternatively, a mixture of materials with various molecular weights such that the average molecular weight value ranges from 1,000 to 6,000 may be used. In the present invention, the amount of polyethylene glycol contained in the solid shower product is approximately 30 to 95% by weight.
It is appropriate to mix them so that By various combinations of the average molecular weight and blending amount of polyethylene glycol, it is possible to freely adjust the dissolution temperature and dissolution time. Next, in the present invention, in addition to polyethylene glycol, one or more ingredients selected from pigments, fragrances, bath additive ingredients, cleaning agent ingredients, cosmetic ingredients, etc. are added depending on the intended solid shower product. Appropriately select and combine them. Specific examples of solid shower products containing such ingredients and intended are as follows. A bathpahyum-like product with added pigments and fragrances for the purpose of enjoying color and fragrance. Bath additive-like products that are added with raw ingredients such as inorganic salts, pigments, and fragrances to achieve color, fragrance, and efficacy. A bubble bath-like product that contains cleansing ingredients (such as anionic surfactants and nonionic surfactants) for the purpose of cleaning the hair and body. A rinse-like product that adds oil-based ingredients, moisturizers, etc. to restore acidity to the alkaline hair and skin after washing, with the aim of softening the hair and skin. A lotion-like product that contains alcohol and fragrance to provide a cooling sensation, fragrance, and astringent effect. Specific examples of inorganic salts, pigments, alcohols, polyhydric alcohols, anionic surfactants, and nonionic surfactants used in these are as follows. Inorganic salts Sodium chloride, sodium hydrogen carbonate, sodium carbonate, borax, sodium sulfate, potassium sulfide, sodium sulfide, sodium sesquicarbonate, calcium oxide, potassium nitrate, sodium nitrate, calcium nitrate, aluminum sulfate,
Magnesium carbonate, sodium thiosulfate, sodium polyphosphate, calcium carbonate, calcium hydrogen phosphate, potassium bromide, potassium chloride,
Ammonium chloride, iron sulfate, heavy magnesium carbonate, sodium phosphate, etc. Pigments Red No. 2, Yellow No. 4, Green No. 3, Blue No. 1,
Red No. 216, Orange No. 205, Yellow No. 202 (1), Green
Natural pigments that are approved as food additives, such as tar pigment table and pigments specified by Ministry of Health and Welfare ordinance such as No. 201 and Blue No. 201, chlorophyll, riboflavin, crocin, cochineal, safflower, anthraquinone, etc. Alcohols ethanol, stearyl alcohol, isopropyl alcohol, cetyl alcohol, hexadecyl alcohol, etc. Polyhydric alcohols glycerin, propylene glycol, sorbitol, etc. Anionic surfactants: sodium lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, etc. Nonionic surfactants such as lauric acid diethanolamide, polyethylene glycol monostearate, polyoxyethylene cetyl ether, etc. In addition to the above-mentioned ingredients, the solid shower product of the present invention may also contain bactericidal preservatives (e.g., benzoic acid, benzoate esters, sorbic acid, etc.), sequestrants (e.g., EDTA, NTA, citric acid, etc.) and sequestering agents (e.g., EDTA, NTA, citric acid). acids, etc.), and a wide range of other raw materials can be blended. Next, in order to manufacture the solid shower product of the present invention, any method can be used as long as it can uniformly mix and solidify the components and polyethylene glycol according to the purpose of use described above. For example, an appropriate amount of the above-mentioned components according to the purpose of use is added to an appropriate amount of polyethylene glycol that has been heated and dissolved in advance, and the mixture is stirred uniformly and then filled into a container (mold) and cooled to solidify, or after solidification, it is molded. It can be manufactured by The solid shower product of the present invention can be used by being inserted into any part of a shower device. For example, the solid shower product of the present invention can be inserted between the shower head and the shower hose of the shower device. Preferably, an attachment is provided which is removably mounted between the shower head and the shower hose, for example by screws or the like. [Effects of the Invention] The solid shower product of the present invention contains pigments, fragrances, bath additive raw ingredients, detergent raw ingredients, cosmetic raw ingredients, etc., depending on the purpose of use, and is compatible with conventional powder products and powder powders. Unlike tablet products, when used in the shower, it takes a long time to dissolve, and the dissolution of color, fragrance, bath agent ingredients, cleaning agent ingredients, and cosmetic ingredients continues uniformly, making it extremely useful as a shower product. Next, we will give an experimental example in which the slow solubility performance of the solid shower product of the present invention and the powder product mixed with a binder and compressed into tablets (bath additives) are compared. Explain that it has excellent slow solubility during use.
