Description

[0101]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet soap, and more particularly to a mineral-containing toilet soap that is gentle on human skin and is useful for bathing and facial cleansing, and is useful for skin health.
[0092]
2. Description of the Related Art Conventionally, soaps containing a mineral component in soap and having not only a cleansing effect but also a skin health effect, that is, a so-called cosmetic effect, in a cosmetic soap have been marketed. These soaps have a mineral component. It is made by adding rocks containing inorganic salts and active ingredients such as sodium chloride to powder.
Further, when taking a bath, bath water containing mineral components is also used, for example, a hot spring is a typical example.
In addition, as a bath additive, a medicinal rock is put in a bathtub to elute mineral components and to purify bath water.
An example of such a rock is barley stone, which is known as a medicinal stone of Chinese medicine, and it is said that bathing in a bath water containing barley stone for a long period of time and habitually contributes to skin health. I have.
Therefore, if barley rice stone is powdered and contained in toilet soap, it can be used not only for bathing, but also for washing the face and hands and feet, using this toilet soap to improve skin health and contribute to beauty. As much as possible, toilet soap with barley stone is also commercially available.

Although these soaps containing barley stone are useful for the health of the skin as such, they have a further effect on the health of the skin and a feeling of use in use (for example, a feeling of roughness). It is also required to be excellent in cosmetics, etc., and even though soap, it is often required to have the same requirements and medicinal properties as cosmetics.
An object of the present invention is to provide a mineral-containing toilet soap which has no side effects even when used for a long period of time, promotes skin health, and gives a moist feeling when used to satisfy these requirements.
[0099]
[Means for Solving the Problems] The present inventors have conducted intensive studies and as a result, by adding olive oil and turmeric to soap in addition to barley rice stone, skin roughness has been eliminated and the skin has been smoothed. The present invention has been found to be effective in whitening effect, itching and improvement of symptoms of dry skin, and to provide a toilet soap which gives a refreshing feeling such as a moist feeling and a moist feeling upon use.
That is, the cosmetic soap of the present invention comprises 1.5 to 10% by weight, preferably 2 to 7% by weight, olive oil 0.5 to 5% by weight, preferably 1 to 3% by weight, turmeric 0.1% by weight. -3% by weight, preferably 0.3-1.5% by weight.
The cosmetic soap of the present invention may further contain a fragrance, a coloring agent, and the like, if necessary. For the purpose of promoting the health of the skin, the cosmetic soap contains no such additive or a synthetic product. It is preferable to use natural fragrances and coloring agents while avoiding the above.
The barite used in the present invention is a kind of rock mainly composed of alkali feldspar and quartz belonging to granite porphyry, and has been used as a medicinal stone since ancient times, and is mined and imported in China. It is mined and produced in Japan.
In the present invention, commercially available barley rice can be used.
In order to incorporate barley rice into soap, the raw stone is crushed and further added as a powder of 100 to 500 mesh to the soap dough at 1.5 to 10% by weight.
In the case of barley rice powder having a particle size coarser than 100 mesh, there is a feeling of roughness when using soap, and in some cases, the skin may be damaged.
Powder having a particle size finer than 500 mesh not only requires time and effort to process from raw stones, but also increases the melt viscosity of the soap material when added to soap, and also takes time to process soap. It is not preferable.
When the amount of barley stone added is less than 1.5% by weight, the effect cannot be expected much, and when the amount exceeds 10% by weight, the effect does not increase, causing a sense of incongruity in the use of inorganic substances during use. Refreshing feeling is reduced, which is not preferable.
Olive oil added to soap dough in an amount of 0.5 to 5% by weight can be used even if it is virgin oil that has been pressed and purified, and any of them can be used. Absent.
When the amount of the added olive oil is less than 0.5% by weight, the moisturizing effect giving a moist feeling and a moist feeling does not appear, and when the amount exceeds 5% by weight, the finished soap becomes soft and becomes a solid soap. It is not preferable because it is difficult to use.
The turmeric added to the soap dough in an amount of 0.1 to 3% by weight may be any of autumn turmeric, spring turmeric (kyoou) and purple turmeric (gajutsu), and may use two or more kinds of each. You can also.
In order to use turmeric in the present invention, the turmeric is a dry powder, and the content is% by weight as the dry powder.
When the amount of turmeric added is less than 0.1% by weight, there is no effect. On the other hand, when the amount exceeds 3% by weight, the medicinal effect does not increase, and on the contrary, the odor increases, which is not preferable as toilet soap.
[0230]
BEST MODE FOR CARRYING OUT THE INVENTION The cosmetic soap of the present invention is prepared by subjecting a fat or oil to saponification or decomposition and neutralization by a boiling method, a neutralization method, an ester saponification method or the like, followed by purification, in the same manner as a conventional soap production method. Separately, a neat soap as a soap dough is prepared, and the above neat soap is mixed with the above-mentioned barley stone, olive oil, and turmeric, and then dried and stamped to produce a neat soap.
In the boiling method, a 10 to 20% aqueous sodium hydroxide solution is added to a vegetable oil such as palm oil, olive oil, soybean oil, cottonseed oil, or coconut oil, or a vegetable oil such as tallow or hardened whale oil, followed by boiling. After saponification, glycerol is fractionated, then separated into neat soap and niger by salting out, a neat soap as a soap material is produced, and the niger is reused in the saponification process.
In the neutralization method, fats and oils are heated to decompose them into glycerol and fatty acids, and the fatty acids recovered and purified by distillation are neutralized with sodium hydroxide to produce neat soap.
In the ester saponification method, fats and oils are transesterified with methanol to produce fatty acid methyl esters, which are then saponified to produce neat soap, and methanol is simultaneously recovered.
A neat soap containing a fatty acid alkali salt as a main component obtained by the above-mentioned boiling method, neutralization method, ester saponification method or the like contains about 30% of water. % Or less, add barley stone, olive oil, and turmeric, and knead and stamp to form a product.
In this case, the neat soap may be prepared by adding barley stone, olive oil, turmeric and the like prior to drying the neat soap, followed by drying, kneading and stamping.
[0292]
The present invention will be described more specifically below.
Using palm oil as a fat or oil, a neat soap produced by a boiling method was dried, and 1.5 kg of commercially available maltstone powder (325 mesh, particle size 40 microns) was added to 38 kg of soap dough having a water content of 10%. Add turmeric (spring turmeric / autumn turmeric 1/1 mixed powder) 0.3 kg, olive oil 0.92 kg (1 liter), mix with a mixer, cut using a kneading extruder while extruding the mixed soap composition・ I made a toilet soap by stamping.
The soap was used as a bath soap and a face-wash soap. The soap provided an exhilarating feeling when used, and it was easy to use without dissolving only the required amount from the surface and losing its shape.
Further, when this soap was used as a bath soap for about a week, the skin became smooth and it was confirmed that it was effective for skin health.
There was also a report that this soap was used by 10 monitors continuously for one month, but no particular side effect appeared, the skin was moisturized, and the skin was moist and moist. .
In addition, it has been reported that sensitive skin and dry skin have been improved, itching of hives has stopped, atopic symptoms have been improved, and skin has become white.
