Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides an excellent moisturizing effect by using sake lees or sake lees extract as it is or by containing it.
It relates to excellent cosmetics that also have the effect of making the skin smooth.

(Conventional technology) Cosmetics have traditionally used oils, amino acids, and polysaccharides to provide moisturizing properties. However, recently, the safety of cosmetics has become an issue, and some products are now containing natural moisturizers such as natural oils, hyaluronic acid, and placenta extract, but they have drawbacks such as stickiness. In addition, the effect of making the skin smooth is currently unknown, and there is currently no natural product that has an excellent moisturizing effect (moisturizing effect) without leaving a greasy feeling, and that also has the effect of making the skin smooth. unknown.

On the other hand, sake lees can only be used to make shochu, shochu, and sweet sake, and it is no exaggeration to say that its main purpose is to make pickles.

As a result, prices have plummeted due to the unavailability of gourds, which not only puts pressure on the business of sake brewing manufacturers, but also leads to the problem of disposing of gourds because there are no takers, which is also a major environmental problem.

In addition, some beer lees and shochu lees are used as medicines due to the yeast they contain, but they are mostly used as feed.

(Problems to be Solved by the Invention) In recent years, there has been a trend toward natural products in all fields, and cosmetics are no exception. This is attracting attention not only from the side effects (but also from the safety point of view.Safety refers to the effects on the skin or the effects of applying it to the skin over a long period of time). absorption, and oral absorption into the body by applying it to the skin, especially on the hands.In other words, it is a problem when you touch your hands with cosmetics when washing food, handling tableware, etc. has been done.

On the other hand, as for the effect on the skin, increasing the moisturizing property makes it sticky, and it hardly ever appears because it is contradictory to the smooth moisturizing property, and on the other hand, if you want to make the skin smooth, the current situation is that it does not become moist. be. In other words, it is a natural product that has been proven to be safe and is non-sticky, and has a moisturizing effect due to the high moisture content of the stratum corneum and the freshness of the dermis (moisture evaporation rate). There is a desire in the cosmetics industry for cosmetics that have both the effects of being moisturizing and making the skin smooth.

(Means for Solving the Problems) The present inventor has been conducting research on various plant ingredients, mainly rice, which is a staple food, from the perspective of preserving animals and plants, and has found that disposal is currently an issue. We have been conducting research and development on the use of sake lees. In the process, rub sake lees into your hands,
When I thoroughly washed my hands with the condensed water and dried them, I found that my hands were moisturized and had a smoothing effect. When we mixed sake lees or sake lees extract into various cosmetics, we found that they were not only more moisturizing than the base, but also less sticky and smoother.

Even with products that involve cleaning, such as facial cleansers, moisturizing and smoothing effects were observed even after washing and rinsing with water. Also, depending on the application, if the product is a liquid such as a lotion, the appearance of the product may deteriorate significantly if it is simply mixed in. Therefore, the filtrate after solvent extraction such as alcohol and water extraction may be used as a lotion base or face wash. When we mixed it into the food base, the effect was more pronounced than if it were just mixed in. Of these, water extraction was far more effective than alcohol extraction. It has also been found that water extraction is more desirable because if a large amount of alcohol-extracted products is added in order to achieve the desired effect, the degreasing power of alcohol is too strong and the product value is reduced.

In any case, by using sake lees or sake lees extract, an extremely excellent cosmetic material with moisturizing effect and smoothness can be obtained, and its effect does not change at all even after washing, so it can be used in all kinds of cosmetics. can do.

Furthermore, when the water extract of sake lees is subjected to alcohol fermentation, the effect of moisturizing the hands becomes even better.

The present invention is based on the above findings, that is, it is a cosmetic product characterized by containing sake lees or sake lees extract as is or containing the same.

In the present invention, the sake lees or the sake lees extract is used as a cosmetic product as it is, or it is mixed into a cosmetic product. Sake lees can be either beer lees or shochu lees, but sake lees has the most noticeable effect. Moreover, the sake lees may be new or old. The degree of dryness may be determined by taking water absorption into consideration depending on the type and form of the cosmetics to be mixed.

If you prefer a liquid version, such as a lotion, add water to the sake lees and extract. The amount of water added to the sake lees is preferably twice that of the sake lees in terms of yield and workability, but it may be more or less. The temperature and time at which it is left at 50°
It is desirable to leave it at C for about 6 hours, but the temperature is 5 to 6.
Adjustment may be made by adjusting the standing time at 0''C. That is, if the temperature is low, the standing time is lengthened, and if the temperature is high, it is adjusted by shortening.

If the temperature is low, there is a risk of spoilage, so
It is necessary to perform preservative measures such as adding preservatives.

Further, the purpose of extraction can be achieved even if the temperature is 60°C or higher, so there is no problem.

Note that in order to facilitate extraction, it is effective to use methods such as enzymatic reaction and hydrochloric acid decomposition. Regarding enzymes, all enzymes that react with sake lees components are more effective than water extraction alone. In other words, the more extraction is done, the more effective it is. Extraction with a solvent such as alcohol may be performed by a conventional method.

The water extract thus obtained may be further subjected to alcoholic fermentation.

The sake lees or sake lees extract obtained as described above can be used as a cosmetic product or mixed into a cosmetic product, but when mixing it, for example, in the case of a facial cleanser, the sake lees can be used as a face wash product. You can mix it into the ingredients or mix it with the extract. A sufficient effect can be obtained with a mixing amount of about 10%, but it will be more effective if the mixing amount is increased. Depending on the application, it may be better to use a powder, but in this case, it can be powdered by spray drying and mixed together.

Next, the effects will be described based on experimental data.

First, in order to demonstrate the moisturizing effect, a 10% aqueous solution of the product of the present invention was applied directly to three women, and then the water evaporation rate was measured. The above-mentioned product of the present invention is the product of the present invention that was squeezed using a squeezing machine in Example 1.

The results are shown in Figure 1. Note that in FIG. 1, the numerical values on the vertical axis are coefficients when water is set to 1.0.

From FIG. 1, it was found that the product of the present invention exhibits a very significant moisturizing effect compared to water. Moreover, the moisturizing effect measured by this measurement method indicates that the moisture supply from the dermis is active, and it indicates not only the moistness but also the freshness of the skin, and can be said to be an excellent effect.

Next, to demonstrate the smoothness, we used artificial leather,
FIG. 2 shows the results measured by a dynamic tribometer after applying a 10% aqueous solution of the product of the present invention. In FIG. 2, the product of the present invention is the product of the present invention that was squeezed using the squeezing machine in Example 1, and the facial cleansing foam base is soap made by saponifying myristic acid and stearic acid (30% as surfactant). is the main component. The measurement method is (1) and (2) after application.
It was dried at 5°C for 25 minutes and measured with a dynamic tribometer.
4) Add artificial leather to each solution (in the case of facial cleanser, add 0.7 g to 10
After soaking in (dissolved in 0cc of distilled water) for 5 minutes,
After thoroughly washing with water and drying at 25°C for 25 minutes, measurement was performed using a dynamic tribometer. The ratio of average coefficient of friction is a comparison percentage when water is taken as 100%.

From FIG. 2, it was found that the product of the present invention was not only moist but also smooth.

Furthermore, recently, there has been a boom in wash-off cosmetics such as facial cleansing foam, so if these effects can be maintained even after washing, it can be used in all cosmetic fields, so we mixed it into facial cleansing foam to demonstrate its effectiveness. That is, the second
As shown in the figure, even after washing, the product mixed with the present invention (2) was much more effective than the base alone.
It was observed that frictional resistance was low, and smoothness and smoothness appeared.

As mentioned above, it was clear that the product was smooth whether applied as is or washed, so we also investigated its moisturizing properties after washing. That is, using artificial leather, it was washed with three items: water, a facial cleansing foam base, and a facial cleansing foam base mixed with the product (2) of the present invention.
Thereafter, it was thoroughly washed with water, dried for a certain period of time, and then the water content was measured over time. The results are shown in FIG. In FIG. 3, the product of the present invention and the facial cleansing foam base are the same as described above. The measurement method is to soak the artificial leather in each facial cleansing solution (for facial cleansers, dissolve 1 g in 100 cc of distilled water), leave it for 10 minutes, rinse thoroughly with water, and store at 25°C.
After drying for 25 minutes, the water content was examined over time. The water content was expressed as %, with the artificial leather before washing having a water content of 0.

As shown in Figure 3, the water content of the face wash with water and facial cleansing foam base decreased rapidly over time, but the product of the present invention (
In the case where 2) was mixed, the water content increased at - and then gradually decreased. This indicates that the product of the present invention greatly improves skin freshness (water retention). After washing, it is said that the water becomes less moist for boat fishing, but by adding the product (2) of the present invention, it becomes moist and fresh, which can be said to be an excellent phenomenon.

As described above, it has been demonstrated that the product of the present invention is both moist and smooth even when applied as is or after washing.

Therefore, in order to confirm this in actual use, we used a panel of two people with different skin types to create facial cleansing foam base,
15% of the product (2) of the present invention was added to a neutral facial cleansing foam base, and the moisture content of the epidermis and stratum corneum before addition was compared over time using a moisture meter. The results are shown in FIG. In FIG. 4, a 23-year-old woman with a normal skin type tested the neutral facial cleansing foam base.

The facial cleansing foam base was monitored by a 22-year-old woman with dry skin with low moisture content. The neutral facial cleansing foam base contains monoalkyl phosphate as a main component, and the product of the present invention and the facial cleansing foam base are the same as those described above.

In addition, to these bases, glycerin and collagen were added in amounts approximately equivalent to those prescribed in general facial cleansing foams in order to more closely approximate the actual conditions in actual use.

From FIG. 4, it can be seen that the moisture content of the skin immediately after face washing gradually recovers, peaks around 60 minutes, and then decreases again. At this time, the moisture content of the product mixed with the present invention (2) after 60 minutes is very high compared to the base without the mixture, regardless of whether it is a neutral facial cleansing foam base or a facial cleansing foam base. I understand. Also, even after 120 minutes,
It can be seen that it contains much more water than the base.

In this way, it was confirmed that the cosmetic product had a remarkable moisturizing effect even after washing, and it was found to be an extremely excellent cosmetic product in practical use. The product of the present invention not only has both a moisturizing effect and smoothness, but also a cleaning effect as demonstrated by the Rienatsu test method and a dishwashing test, as well as foaming power in the Ross Miles method. It has remarkable effects in many fields.

2 (Effects of the invention) As is clear from the above analytical data, by using sake lees or sake lees extract as is or by incorporating it into cosmetics, it is possible to make the skin moist and fresh, and also to make it smooth and smooth. It has been found that both effects can be achieved in a well-balanced manner. This is something that has been thought to be difficult to achieve until now.
Both effects were achieved using sake lees, a natural, safe and inexpensive product. Moreover, since both of these effects are maintained even after washing, it can be used in all kinds of cosmetics, making it extremely versatile. Furthermore, this invention increases the added value of sake lees, which is currently being disposed of, and opens up a market in a completely different field than before, making this invention extremely meaningful for both sake brewers and cosmetics manufacturers. be.

(Example) Next, examples of the present invention will be described.

Example 1 15 kg of sake lees was added to 60°C warm water 301, stirred thoroughly and adjusted to 45°C, and left at that temperature for 10 hours. Then, in order to improve the extraction, it was boiled to 90°C, cooled to about 30°C, and then squeezed using a squeezer. , and a residue of 16 glazes was obtained.

On the other hand, (1) add 6 parts of potassium hydroxide to 25 parts of purified water and heat; (2) heat and melt 30 parts of myristic acid, 7 parts of stearic acid, and 7 parts of lipophilic glyceryl monostearate; First, 10 parts of glycerin was added to ■ and the temperature was immediately adjusted to 70°C, and then ■ was gradually added to this while stirring well to make soap. This was cooled to 40 to 50°C while stirring thoroughly, and the above-mentioned invention product 15
1 part and further cooled to 35°C to obtain 95 parts of a product of the present invention different from the above.

Example 2 Add 15kg of sake lees to 30ffi of 60°C warm water,
After adjusting the temperature to 50°C, 10 g of lipase was added, stirred thoroughly, and left to stand for 6 hours while maintaining the temperature at 50°C.

Then, in order to improve the extraction, the product was boiled to 90°C, cooled to about 30°C, and then squeezed using a squeezer. , and 16 kg of residue was obtained.

Further, 10 parts of the above-mentioned invention product, 10 parts of ethanol, 0.04 part of paraben, and 0.3 parts of sodium benzoate were diluted with purified water to make 100 parts to obtain another invention product.
