Description

TECHNICAL FIELD The present invention relates to cosmetics. More specifically, the present invention relates to a powdered cosmetic containing a processed lees of sake lees excellent in long-term storage stability, which is a mixture of rice lees, which is a rice-derived ingredient excellent in skin protection, and rice flour.

[Prior Art] Sake lees have been conventionally used as a raw material for edible products such as amazake, sake buns, and kasu soup, and as seasoning materials such as Nara pickles, wasabi pickles, and fish pickles. In recent years, in the field of cosmetics as well, attention has been paid to proteins, amino acids, starches, yeasts, vitamins and dietary fiber contained in sake lees, and putty-like packs based on sake lees (Japanese Patent Application Laid-Open No. Sho
59-164711) and bath agents (JP-A-62-106008).

However, when the sake lees are left to stand for a long period of time, their components and the like change and soften, and browning occurs, and at the same time, the odor also changes, which is not preferable as a cosmetic raw material. Although various modifications have been carried out for the purpose of preventing these, sake lees-containing cosmetics having satisfactory long-term storage stability have not yet been obtained so far.

[Problems to be Solved by the Invention] Therefore, as a result of intensive studies in view of the present situation, the present inventors have found that it is possible to prevent discoloration and odor of sake lees, and moreover, it is safe with a protective effect on the skin. The present invention has led to the discovery of a highly processed sake lees treated product and the development of new powder cosmetics containing such treated products.

[Means for Solving the Problem] That is, according to the present invention, a mixture of sake lees and rice flour from which the red rice bran portion of brown rice has been removed is added with water and dispersed, and the mixture is heated, and then a treated product that is dried is blended. The present invention relates to a powdered cosmetic containing a processed sake lees, which is characterized in that

[Operation and Examples] As described above, the powder cosmetic of the present invention is a mixture of the raw material which is obtained by adding water to a mixture of sake lees and rice flour and dispersing the mixture and subjecting the mixture to heat sterilization and drying.

As described above, the sake lees include proteins, amino acids, starch, yeast, vitamins, dietary fiber, etc.,
Such sake lees are useful ingredients for imparting a skin protective effect to the obtained powder cosmetics.

Specific examples of such sake lees include ginjo sake lees, first grade sake lees, and second grade sake lees, and in the present invention, these are used alone or in combination of two or more.

The rice flour is about 8% (wt%,
The same applies to the following), preferably 10% or more of rice flour obtained after removing the red rice bran portion, but rice flour with 50% or more of the rice polishing portion of the brown rice (rice by-product of brewing sake rice Shiranuka) is more preferable. When the residual rate of the red rice bran part exceeds 92% with respect to the brown rice, the unpleasant odor of the rice bran tends to be strong, and the color and odor tend to change with time. Further, in the case of rice flour having a residual rate of the rice-polishing part of less than 50% with respect to brown rice, the skin tends to be easily degreased.

The mixing ratio of the sake lees and rice flour (sake lees / rice flour: weight ratio) is 20
/ 80 to 80/20, preferably 30/70 to 60/40. If the mixing ratio exceeds 80/20, the resulting powder cosmetic tends to be discolored or odor during storage.
When the amount is less than the above, the skin-protecting effect of sake lees tends to be small, and when water is added, it tends to become mama-like.

The mixture of sake lees and rice flour is heated after adding water. As such water, purified water is usually used, and the water is usually added in an amount of 150 to 500 parts, particularly 300 to 350 parts, relative to 100 parts of the mixture (parts by weight, hereinafter the same). When the amount of water added is less than 150 parts, the mixture and water tend to be difficult to knead, and when more than 500 parts, work efficiency such as freeze-drying tends to be poor. There is.

Further, the heat treatment is performed for sterilization,
The heating temperature is preferably 55 to 90 ° C, especially 80 to 85 ° C. If the heating temperature is lower than 55 ° C, the sterilization treatment tends to be insufficient or takes too long, and if it is higher than 90 ° C, quality deterioration such as discoloration or odor is likely to occur. Tends to become.

Next, the mixture is allowed to cool to room temperature and then dried. Examples of such a drying treatment method include a vacuum freeze drying method and a spray drying method. Among these methods, the spray-drying method requires high-temperature operation, and therefore the quality of the raw material to be treated is likely to deteriorate. Therefore, it is preferable to perform drying by the vacuum freeze-drying method.

Such a vacuum freeze-drying method, the mixture of heat-sterilized sake lees and rice flour and water are transferred to a freeze-dryer, cooled to about -40 to -20 ° C and frozen, and the temperature is set to 20 in a reduced pressure atmosphere.
It is a method of obtaining a dried product by gradually increasing the temperature to 0 ° C, for example, with a temperature gradient of 0.04 to 0.06 ° C / min.

The degree of pressure reduction in the freeze dryer is 0.1 to 0.2 mm.
It is preferably Hg.

The dried product obtained next is further pulverized by, for example, a sample mill or a Henschel pulverizer to obtain a particle size of 80.
It is adjusted so that the processed sake lees are less than the mesh pass. When the particle size is larger than 80 mesh pass, the resulting processed lees of sake lees tend to have a poor feel and also have poor solubility in water.

The sake lees treated product-containing powder cosmetics of the present invention can be obtained by appropriately blending the thus treated sake lees treated product with cosmetic ingredients such as an excipient, a fragrance and an active ingredient.

The content of the treated sake lees in the powdered cosmetic containing a treated lees of the present invention is usually 1 to 90%, preferably 5 to 80%, more preferably 40 to 70%. When the content is less than the above range, the skin protecting effect of the obtained powder cosmetic tends to be small, and when it exceeds the above range, sake lees which are not preferable as cosmetics when the obtained powder cosmetic is used. The odor tends to be too strong.

As described above, the cosmetic ingredients are appropriately blended according to the application such as powder cleansers, powder packs, powder hair wash.

Examples of such cosmetic ingredients include excipients, fragrances, surfactants, preservatives, pigments, active ingredients and the like.

Examples of the excipient include white rice bran powder, lactose, glucose, maltitol, polyhydric alcohols such as 1,3-butylene glycol and polyethylene glycol, starch,
Examples include water-soluble polymers such as dextrin, methyl cellulose, crystalline cellulose, carboxymethyl cellulose and bentonite, and oil agents such as olive oil, squalane, cetanol, stearic acid and methyl polysiloxane. These components may be used alone or in combination of two or more. Used as a mixture.

Examples of the surfactant include sorbitan sesquioleate, trioleyl phosphate and the like.

Examples of the preservative include paraoxybenzoic acid ester, dehydroacetic acid and salts thereof, and the like.

Examples of the pigment include extender pigments such as talc and kaolin, inorganic pigments such as zinc white, titanium oxide, red iron oxide, and yellow iron oxide, organic pigments such as Blue No. 1, pearl pigments such as mica, fish scale foil, and bismuth oxychloride. And so on.

The active ingredient is appropriately selected according to the use of the powder cosmetic of the present invention. Specific examples of the active ingredient include vitamins such as vitamin A, vitamin C, vitamin D and nicotanic acid. β-glycyrrhetinic acid, anti-inflammatory agents such as lysozyme chloride, allantoin, humectants such as urea, hyaluronic acid, elastin, collagen, aloe, and shikon, amino acids such as serine, proline, and glycine, oxybenzone, urocanic acid, paraaminobenzoic acid UV absorbers such as ethyl, N-stearoyl-
Acyl amino acid salts such as sodium L-glutamate, sodium lauroylsarcosine, potassium coconut oil fatty acid methyl taurine, alkali salts of fatty acids, monoalkyl phosphates such as sodium monolauryl phosphate, alkylsulfosuccinic acid such as sodium α-olefinsulfonate. Examples include mild detergents such as salt.

Since the blending amount of each of these cosmetic ingredients differs depending on the intended use of the cosmetic, it cannot be unconditionally determined. Therefore, it is preferably adjusted appropriately according to such use.

Thus, the powdered cosmetic containing the processed sake lees of the present invention is excellent in long-term storage stability and is a mixture of processed sake lees which is safe for the human body. It has the excellent property that no significant discoloration or odor is generated.

Next, the powdered cosmetics containing the processed sake lees according to the present invention will be described more specifically based on Examples and Comparative Examples, but the present invention is not limited to these Examples.
