Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cosmetic composition capable of significantly increasing moisturizing feeling and beautiful skin feeling such as moist feeling, shiny feeling and smooth feeling after use.

Rice bran is a mixture of pericarp, seed coat, germ, aleurone powder, etc., which is removed when brown rice is attached to remove white rice. And it contains about 15% protein and about 15% fat,
It is a nutrient source that contains a large amount of carbohydrates, various vitamins such as vitamins B ₁ and E, and minerals. In Japan, it has long been used as a cosmetic for bran bags, etc. for the beauty of the skin and hair. It has long been thought that the cosmetic effect is brought about by oil-soluble components such as bran oil (flurulic acid esters of triterpene alcohol) contained in bran, vitamin E, fatty acids, and higher alcohols.

However, as a result of earnest research, the present inventor has paid attention to the fact that the bran bag is always used for beauty after being melted in water or hot water. As a result of the research, the water-soluble polysaccharide present in rice bran has a cosmetic effect. It was found that the cosmetic effect can be synergistically enhanced by finding out that it is a substance and further extracting and adding the pigment component in the brown sugar to the present invention.

The rice bran extract of the present invention is one or more kinds of polysaccharides (Oryzabran), and is obtained, for example, by the following method. Three times weight of water is added to rice bran and cold soaked for 3 days. This operation is repeated 3 times, the extract is filtered, and water is distilled off. The obtained evaporated extract is dissolved in the same amount of water, and lower alcohol (ethanol) is added thereto in an amount of 4 times the weight of the extract. The deposited precipitate is collected by filtration, washed well with a lower alcohol, and dried at a low temperature to manufacture. The water extraction may be heat extraction. Instead of adding a lower alcohol, an aqueous solution of water-soluble copper salts such as copper sulfate and copper acetate is added to form a polysaccharide-copper conjugate, and the precipitate is collected by filtration. It may be produced by suspending in a mineral acid aqueous solution, washing well to elute copper, removing copper from the bound substance, thoroughly washing free components with a lower alcohol, and drying.

The obtained rice bran extract is light brown to white and easily dissolved in water, and alcohol, ether, benzene, chloroform,
Hard to dissolve in ethyl acetate. In addition, when this product is analyzed by liquid chromatography, four kinds of polysaccharides Oryzabran A, B, C, D composed of CHNO having different molecular weights are used.
Of at least one of

In addition, cosmetics in which crude sugar, so-called brown sugar, is added as it is, for example, brown sugar soap is said to whiten the skin, and has been used for a long time. The present inventors have found that the pigment component in this brown sugar (phenyl glucoses containing specific oligos, etc.) has a moisturizing effect on the skin and a skin-beautifying effect, and the action effect is combined with the rice bran extract. It was found that by doing so, it was further enhanced. The brown sugar extract according to the present invention is a phenyl glucose containing substantially pure brown sugar pigment component, that is, a specific oligosaccharide.

 This pigment component is extracted by the following method, for example.

The crude sugar is dissolved in water and treated with an adsorbent. As the adsorbent, a porous cross-linked polystyrene resin adsorbent having a huge network structure, such as Amberlite XAD-2 (ROHM
And Haas), Selvachrome XAD-Type 2
The use of (Selva) or the like is preferable.

The adsorbent is washed with water to remove sugar and make only the pigment component adsorbed.

Desorption of the dye component from the adsorbent is performed at an alcohol concentration of 20
It is desirable to use a hydrous alcohol content of at least%.
Specifically, for example, most of the dye components are eluted with about 20% to 30% ethanol, and then completely eluted with about 95% ethanol.

 The eluent is evaporated to dryness under bottom pressure.

The pigment component can be extracted by the above operations 1 to. The extracted pigment component is substantially pure and sugar-free. Therefore, when forming a cosmetic, it can be added to the base in an arbitrary amount, independently of the sugar. That is, the cosmetic of the present invention is capable of imparting a high level of cosmetic effect due to the pigment component to the skin without being affected by sugar.

The dosage form of this cosmetic may be any of lotion, lotion, cream, skin cosmetics such as packs, shampoo, conditioner, hair tonic, treatment, hair cosmetics such as hair cream, and other bath agents and soaps. .

As the cosmetic base used in the cosmetic of the present invention, those known in the art may be used.

In addition, the cosmetics of the present invention include fragrances, antioxidants, preservatives,
Various additives such as a surfactant may be appropriately added as needed.

The amount of the rice bran extract and brown sugar extract according to the present invention is 0.0001 to 10.0% by weight, preferably 0.01 to 10% by weight, and the brown sugar extract 0.001 to 3% by weight, preferably 0.01 to 1% by weight, in cosmetics. %, The combination amount of both is preferably 0.01 to 10% by weight of rice bran extract and 0.01 to 0.5% by weight of brown sugar extract.

 Examples of the present invention will be described below.

The effects of the present invention will be made more apparent by showing Comparative Examples together with Examples.
