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 towels, 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 solid shower product is characterized by containing about 30 to 95% by weight of alkoxypolyethylene 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. The alkoxypolyethylene glycol used in the present invention can be produced according to conventional methods.
For example, it can be produced by reacting sodium alkoxide and ethanol to synthesize alkoxyethylene glycol and adding ethylene oxide to it. can be manufactured. Its synthetic route and chemical structure are represented by the following general formula. [In the formula, R is an alkyl group, and n is an integer] Examples of the alkoxypolyethylene glycol used in the present invention include those whose alkoxy group is a methoxy group, an ethoxy group, a propoxy group, a butoxy group,
Those having a pentoxy group etc. are suitable, and those having an average molecular weight of 1000 to 6000 are preferably used. 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 alkoxypolyethylene glycol contained in the solid shower product is approximately 30
It is appropriate to mix it so that it is 95% by weight. The melting temperature and melting time can be freely adjusted by various combinations of the carbon number, average molecular weight, and blending amount of the alkoxy group of the alkoxypolyethylene glycol. Next, in the present invention, in addition to the alkoxypolyethylene glycol, one selected from pigments, fragrances, bath additive raw ingredients, detergent raw ingredients, cosmetic raw ingredients, etc., depending on the intended solid shower product, is used.
A suitable combination of one or more components is contained. 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.
