DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved composition of a transparent or translucent solid soap, and more particularly to a composition obtained by uniformly dispersing a flaky substance in a soap solid. .

[0002]

2. Description of the Related Art Conventionally, the appearance of a transparent solid soap has been improved in order to increase its commercial value, and various additives have been blended. Regarding the improvement of the appearance of solid soap, for example, in order to give a pearl-like appearance, a metal foil piece or a thin flake colored on one side of an inorganic substance such as mica was dispersed and blended in a soap solid. Things can be mentioned.

[0003] JP-A-63-225699 discloses a method in which gold foil pieces are dispersed and mixed in soap solids. In addition, there is also a product in which powder granules are dispersed and blended in soap solid (Japanese Patent Application Laid-Open No. 61-195200). There is also a resin film obtained by crushing or cutting a metal-deposited material on a resin film and dispersing and blending this fragment in a soap solid (Japanese Patent Publication No. 2-24320, Japanese Patent Publication No. 4-25999). .

[0004] The above-mentioned technique is also related to the improvement of the composition of various additives. In other words, gold leaf-containing soap focuses on the medicinal properties of the gold foil itself, and powder-granulated material-containing soap combines perfatty acids such as hydrocarbon oils and other additives with the powder granules. By blending these additives, defects such as a reduction in foaming in the additive composition and a change in odor and discoloration due to the reaction with the soap base were eliminated.

[0005]

However, the above-mentioned conventional composition has the following disadvantages. First, as for the gold-foil-containing soap, the specific gravity is excessive with respect to the soap base material, so that it is difficult to uniformly mix the same, which makes the production operation difficult, and the gold leaf itself is not easily soluble in water. For,
There are drawbacks such as a feeling of foreign matter during use and adhesion to the skin surface, and high cost of the product due to its high cost.

[0006] In addition, regarding the powder granulated compound compound soap,
Although it is effective to contain various additive components without any adverse effect, it is difficult to obtain sufficient solubility or disintegration in water due to its granulated form. It is also difficult to act on it, and in some cases, it may cause a foreign-body sensation during use. In addition, a pal-like form cannot be obtained in appearance.

[0007] In addition, in the case of soap containing metal film-deposited resin film pieces, a pal-like form can be obtained in a uniform state by mixing the thin pieces. Not intended
Therefore, a foreign substance sensation may be caused in use, and the additive component cannot be contained in relation to the resin film. Therefore, it is difficult to mix the above-mentioned perfatty acid and the like without any adverse effect.

Accordingly, the present invention can provide various appearance forms such as pearls and the like, can be used without detrimental effects upon use, and effectively contain various powdery or liquid additive components. An object of the present invention is to provide a transparent or translucent solid soap in which flake-like substance pieces that can be mixed are uniformly mixed.

[0009]

In order to achieve the above object, the present invention provides a transparent solid soap having the following composition. That is, by coating a colorant on the surface of the easily decayable flake-like substance, a treated flake having a specific gravity of 1.0 to 2.0 is formed, and the treated flake is made of a transparent or translucent soap base material. It is characterized by being compounded in a uniformly dispersed state therein.

In the composition of the present invention described above, the flake-like substance refers to a flake obtained by the following production method. That is, it is obtained by dissolving a readily decayable substance, solidifying it on a cooling drum surface while developing it in a sheet shape of, for example, 0.5 mm thickness, and crushing it to scrape it. Therefore, the shape is not particularly limited, and the thickness is not limited, but the thickness is preferably 0.1 to 1.5 mm. If the thickness is less than 0.1 mm, it is difficult to adjust the specific gravity. If the thickness is more than 1.5 mm, the time for erosion becomes longer, which may cause a feeling of foreign matter during use.

The size is preferably 0.3 mm on each side.
It is within the range of ~ 16mm. If this is less than 0.3 mm, the effect on the appearance will not be obtained, and 16 mm
This is because, in the above case, uniform blending becomes difficult, and a foreign-body sensation is caused during use. The size can be selected within a certain range through a sieving process. The flake-like substance in the present invention is not limited to the above-mentioned production method.

The base material of the flake-like substance itself is readily soluble in water and preferably has a melting point in the range of 40 to 80 ° C. and a specific gravity of 0.7.
It is preferably from 1.4 to 1.4, and for example, polyethylene glycol, behenyl alcohol, monosteering cellulose, polyoxyethylene oxide polypropylene oxide block polymer and the like can be used.

In the above-mentioned base material, various organic powders or inorganic powders are incorporated with a disintegration improver, a specific gravity adjuster,
In addition, moisturizers, whitening agents or fungicides, for example, 1
It can be appropriately mixed at a ratio of up to 10% by weight. In addition,
The size of these powder particles does not cause a foreign object feeling when used as soap, and is preferably 500 μm or less.

The above-mentioned powder is specifically as follows. As a disintegration improver, polyethylene powder,
Talc, titanium oxide, kaolin, silicic anhydride, nylon powder, crystalline cellulose powder, zinc white, etc., and their powders can be used as a specific gravity adjuster. In other words, when the specific gravity of the base material is 1.1 or more, by mixing polyethylene powder, nylon powder, etc., and when the specific gravity is 1.1 or less, titanium oxide, silicic anhydride, kaolin, crystal The specific gravity of the flake-like substance can be adjusted by mixing the natural cellulose powder, zinc white and the like.

As a humectant, an animal extract powder such as hyaluronic acid, sodium hyaluronate, chondroitin sulfate, sodium chondroitin sulfate, collagen powder, etc.
Examples include vegetable extract powders such as alge colloid, saponin, silk fibroin, and wheat protein hydrolyzate.

As a whitening agent having a tyrosinase inhibitory effect, powders of oil-soluble licorice extract powder, arbutin, vitamin C, etc., and as fungicides, hinokitiol,
Powders such as photosensitive element 301 and photosensitive element 201 can be used.

As the coloring agent, in addition to pigments such as a so-called pearling agent as a brightening agent, various substances such as paints can be used together with or without a binder. In addition, when coating the pearling agent,
As a binder, gum arabic, methylcellulose, carboxymethylcellulose, polyvinyl alcohol, ethylcellulose, polyvinyl acetate, acetylcellulose,
Polyacrylic acid derivative, hydroxypropyl cellulose
Water, carrageenan, gelatin, sodium alginate and the like can be used by dissolving them in a solvent such as water or ethanol.

As a method for coating the colorant, for example, a fluidized-bed granulator is used to apply the above-mentioned brightener solution to the flake-like substance in a state of being sowed in accordance with the blowing action of the air flow. It can be by means of spraying.

The coating amount of the colorant is preferably about 3 to 20% by weight based on the obtained treated flakes. If the amount is less than 3% by weight, good coloration, especially good parlness is not obtained when the agent is a pearling agent, and if the amount is more than 20% by weight, the disintegration property of the flake-like substance decreases. This is because the specific gravity adjustment becomes difficult.

The above-mentioned flake-like substance can be compounded by previously kneading various liquid additives. Examples of this liquid additive include isopropyl myristate, isopropyl palmitate, diester malate, myristyl lactate, glycerine trimyristate, 12 hydroxystearate, hexyl lanolinate, propylene glycol monostearate,
Examples include esters such as jojoba oil, hydrocarbon-based substances such as liquid paraffin, silicone oil, and olefin oligomers, vitamins, animal extracts, plant extracts, flavors, drugs, and sugars.

Examples of the transparent or translucent soap base on which the above-mentioned flake-like treated flakes are to be uniformly dispersed include common materials such as saponified products of fats and oils and fatty acids. -A long-chain acyl acidic amino acid salt as a main raw material can be used.

In this case, in order to mix the treated flakes in a uniformly dispersed state, a fixed amount of the treated flakes are mixed and mixed in soap gel in a dissolved state, and the mixed material is cooled and solidified in a frame. It can be obtained by stamping the dried product.

[0023]

When a readily decayable material is blended in a flake form in a soap base material in a dispersed state, the decay performance of the material in running water is reduced when used as soap. In a further improved state, a collapsed state is quickly exhibited. Therefore, the liquid additive contained in the flake-like substance is quickly dispersed in the above-mentioned running water.

The powdery or liquid additive contained in the flake-like substance is blended in the soap base without any adverse effect, and is contained in the above-mentioned running water. In combination with the easy disintegration property of the compound, it is quickly dispersed and its effect is exhibited.

In this flake-like substance, the colorant is coated on a wide surface of the flake-like substance. A variety of appearance forms in which the colored form of the wax-like substance can be effectively confirmed.

The coating composition of the coloring agent is as follows:
It acts to adjust the specific gravity of the flake-like substance. That is, depending on the coating amount of the colorant having a specific gravity larger than the specific gravity of the flake material, the specific gravity is 1.0 to 2.0,
Preferably, it can be adjusted to have a specific gravity of 1.1 to 1.4. The specific gravity value in this range is almost the same as the specific gravity value of the soap base material, whereby the treated flakes of the flake-like substance can be uniformly compounded in the soap base material only by simple mixing. Becomes

The coating composition of the coloring agent is as follows:
At the time of mixing into the soap glue, the flake-like substance also acts as a protective film so that it does not collapse.
