Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a novel bathing agent which, when added to a bath, instantly gives an emulsion-like bath with a rich color tone.

[Conventional technology]

In order to further enhance the bathing effect of relieving the fatigue of the day and relaxing the mind and body, a bathing agent containing a fragrance or pigment has been developed (see, for example, Japanese Examined Patent Publication No. 52-21574). Regarding this color, by trying out various colors that Sara-yu does not have, it is intended to have the same psychological effect as the on-ground effect of hot springs, but in reality there are limits to the pigments that can be used, and more It was desired to improve so that many colors could be enjoyed.

In particular, when an inorganic pigment that is insoluble in water is used, it settles within a few minutes after being poured into the bath water, and it accumulates at the bottom of the bath, which in turn causes discomfort to the bather. There was a point.

Therefore, as a result of research by the present inventors in order to improve this, as a result of coating an inorganic pigment with a water-soluble polymer substance and using this as a bathing agent, good dispersibility and stable bath water We have succeeded in obtaining a bathing agent that is pleasing to the public and have previously filed an application (JP-A-63-57516).

[Problems to be Solved by the Invention] However, when further improving this cloudy type bath agent and blending various water-soluble dyes in an attempt to make it more rich in color, a water-soluble dye is simply added. Just by blending it in the bath additive, when the bath additive is dissolved in the bath water, the water-soluble dye will dissolve in a stringy state, and depending on the particle size and other conditions, it will not dissolve smoothly,
It has been found that there is a problem that it floats on the surface of the water or floats in the water as particles, which rather gives the bather an unpleasant feeling.

The present invention solves this problem, and when added to a bath water, the bath water instantly changes into an emulsion-like bath water with a rich color tone, and that state is maintained stably. Is intended to be developed.

[Means for solving the problem]

As a result of intensive studies, the present inventors have found that the above object can be achieved by coating a water-insoluble inorganic substance with a water-soluble polymer substance mixed with a water-soluble dye, and arrived at the present invention.

That is, the present invention, after adding 50-200 parts by weight of water-soluble polymer substance and 0.001-20 parts by weight of a water-soluble dye to 50-300 parts by weight of water and dissolving them, add 50-150 parts by weight of a water-insoluble inorganic substance. A colored bath agent containing a water-insoluble inorganic substance coated with a water-soluble polymeric substance mixed with a water-soluble dye obtained by drying and then pulverizing the dispersion obtained as a necessary component is provided. is there.

 Hereinafter, the present invention will be described in detail.

Examples of the water-insoluble inorganic substance used in the present invention include titanium oxide, zinc oxide, magnesium oxide, calcium carbonate, magnesium carbonate, talc and the like.

The water-soluble polymer substance used in the present invention is a natural polymer substance,
Both semi-synthetic polymeric substances and synthetic polymeric substances can be used.

Examples of water-soluble natural polymer substances are dextrin,
Examples thereof include microbial polysaccharides such as xanthene gum, plant polysaccharides such as starch, guar gum, carrageenan, agar and mannan, and animal proteins such as gelatin, casein, albumin and collagen.

Examples of water-soluble semi-synthetic polymeric substances include cellulosics such as methylcellulose, ethylcellulose, carboxymethylcellulose and hydroxyethylcellulose, starches such as soluble starch and methylstarch, alginates such as alginate and propylene glycol alginate. You can

Examples of water-soluble synthetic polymer substances include polyvinyl alcohol, carboxyvinyl polymer, sodium polyacrylate, polyvinyl methyl ether, polyethylene oxide and the like.

As the water-soluble dye used in the present invention, either a tar dye or a natural dye can be used.

Examples of water-soluble tar dyes are Blue No. 1 and Blue No. 2
No. 2, Red No. 2, Yellow No. 4, Green No. 3, Red No. 213, Orange 2
The dyes listed in Appendices I and II of the Ministry of Health and Welfare Ordinances such as No. 05, Yellow No. 202-1, and Green No. 204 can be mentioned.

On the other hand, examples of water-soluble natural pigments include chlorophyll, riboflavin, annatto, canthaxanthin, crocin, cochineal, safflower anthraquinone, and the like.

 Next, a method for producing the bath salt of the present invention will be described.

To 50 to 300 parts by weight of purified water, 50 to 200 parts by weight of the above water-soluble polymer and 0.001 to 20 parts by weight of the water-soluble dye are added, and dissolved by stirring at 20 to 80 ° C for 0.5 to 3.0 hours.

50 to 150 parts by weight of a water-insoluble inorganic substance is added to this, and the mixture is stirred at room temperature for 10 to 15 minutes and dispersed.

Place this dispersion in a constant temperature blow dryer at 100-150 ° C for 10-
Dry for 30 hours.

Next, this is crushed to 60 to 200 mesh with a crusher such as a micro bantam mill and a universal ball.

As described above, it is possible to obtain the water-insoluble inorganic substance powder coated with the water-soluble polymer substance in which the desired water-soluble dye is mixed.

In order to stably maintain the emulsion with a rich color tone of the bath water, which is a feature of the present invention, it is important to use each raw material in the above-mentioned quantitative ratio together with the above method. That is, water 50-30
0 parts by weight, water-soluble polymer substance 50 to 200 parts by weight, inorganic substance 50
To 150 parts by weight, and particularly preferably, the three are used in substantially the same amount.

If the amount of water is less than the above range, the dispersibility of the coated inorganic substance in water will decrease, and if it is too much, the function of the water-soluble polymer substance will be weakened.

Further, if the amount of the water-soluble polymer substance is less than half that of the inorganic substance, the coating becomes incomplete, and if it is too much, the water-soluble polymer substance may float on the surface of the molten metal or adhere to the bath.

The particle size of the inorganic substance coated with water-soluble polymer is 60 ~
200 mesh range is good. If the particle size is out of this range and the particle size is too small, the particles coagulate with each other and precipitate, and the emulsion value of the bath water deteriorates to lower the commercial value, which is not preferable. Also, if it is too large, dispersion becomes unstable, which is not preferable.

The proportion of the water-insoluble inorganic substance of the present invention in the bath additive is preferably 0.1 to 20.0% by weight of the total bath additive.
