Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition containing a calcified extract of seaweed of the genus Akkeshishimo and / or Ishimo or a pulverized product thereof. More specifically, by adding an extract extracted from the seaweed of the genus Akkeshishimo and / or Isimo, or a crushed product of the seaweed of the genus Akkeshishimo and / or Isimo, to skin cosmetics and hair cosmetics, high safety is obtained. While maintaining, it moisturizes the skin, smoothes the skin and protects the hair. For example, cosmetics (various preparations used for humans and other animals), pharmaceuticals,
It can be used for quasi drugs, bath agents, etc.

[0002]

2. Description of the Related Art Seaweeds of the genus Akkashiishimo and / or the genus Isimo are seaweeds that grow all over the world and belong to the order Rhodophyta Coralles. The seaweed of the genus Ackishi and / or the genus Isimo is a kind of so-called lime algae and is characterized by depositing a large amount of calcareous in the body. Until now, the utilization of seaweeds of the genus Akkeshii and / or Isimo has been used, for example, in Phymatolit of the genus Akkeshii found in the suburbs of Ireland.
hon calcareum (also known as Lithothamnion calcareum) is calcified and accumulated on the seabed as fertilizer as a calcium source.
It is used for feed and food, but it is hard to say that it is still being fully used.

[0003]

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a novel cosmetic compounded with an extract and / or a pulverized product thereof obtained from a mineral-rich calcified seaweed of the genus Akkeshishimo and / or Ishimo. To provide a fee.

[0004]

[Means for Solving the Problems] As a result of intensive studies conducted by the present inventors to achieve the above object, an extract obtained from calcified seaweeds of the genus Ackishi and / or Isimo (hereinafter referred to as seaweed extract) And seaweed powder (hereinafter abbreviated as seaweed powder) contain a large amount of minerals effective for the skin and at the same time have high safety, and also have the action of smoothing the skin and protecting the hair. The present invention has been completed and the present invention has been completed.

[0005] That is, the present invention is a cosmetic composition containing a seaweed extract obtained by extracting calcified seaweeds of the genus Schinopsis and / or Isimo with water, alcohols, or a mixed solvent thereof. The present invention is also a seaweed powder-containing cosmetic composition obtained by crushing calcified seaweed of the genus Squecipsis and / or Isimo.

[0006] Hereinafter, the present invention will be described in detail. The seaweed extract or seaweed powder, which is the active ingredient of the cosmetic of the present invention, is not particularly limited as long as it is a red alga belonging to the calcified genus Akkeshishimo and / or Ishimo. Phymatolithon calcar
Eum is preferably used. The seaweeds of the genus Ackishi and / or the genus Issimo are characterized in that calcium carbonate is deposited on the cell membrane, and have the property of depositing on the sea floor without decay even after the seaweed withers. The calcification in the present invention refers to a state in which it is hardened by the deposition of calcium carbonate as described above.

[0007] The seaweed extract can be prepared by extracting the calcified seaweed of the genus Akkeshishimo and / or Ishimo with a dilute acid, an acidic buffer, or a mixed solvent of them and an alcohol. It is desirable to extract the seaweed extract after drying the calcified seaweed of the genus Akkeshishimo and / or the genus Ishimo and thoroughly washing the seawater and impurities with water. The seaweed of the genus Akkeshishimo and / or the genus Ishimo, from which seawater and impurities have been removed, can be extracted as it is from the original alga, but may be sterilized, dried, and pulverized before being subjected to extraction. As the extraction solvent, dilute acid, acidic buffer,
Alternatively, a mixed solvent of them and alcohols is used. Examples of the dilute acid include dilute hydrochloric acid, dilute citric acid, dilute acetic acid, and dilute lactic acid. Examples of the acidic buffer solution include citrate buffer solution, lactate buffer solution, acetate buffer solution and the like. The concentration of the dilute acid is sufficient so that the seaweed is almost dissolved, and 0.001 to 0.5 mol of acid per 1 g of the seaweed may be used, but more preferably 0.005 to 0.1 per 1 g of the seaweed.
Preference is given to using molar acids.

[0008] As the alcohols, both monohydric alcohols and polyhydric alcohols can be used. Specifically, as the monohydric alcohol, methanol, ethanol, propyl alcohol, butyl alcohol, isobutyl alcohol,
Examples of the polyhydric alcohol include benzyl alcohol, and ethylene glycol, propylene glycol, glycerin, 1,3-butylene glycol and the like.

[0009] When a mixed solvent of water and alcohols is used as the extraction solvent, the alcohol concentration is preferably 10 to 90%. Specifically, hydrous ethanol with an ethanol concentration of 20-70% and 1,3-butylene glycol concentration of 20-70%
Solvents such as 1% water-containing 1,3-butylene glycol are preferably used. The extraction operation is not particularly limited, but for example, a crushed product 1 of dried seaweed genus and / or seaweed 1
It is preferable to use 5 to 200 times by weight of the extraction solvent with respect to parts by weight. Further, more preferably, the extraction solvent is 20 to
It is preferable to use 100 times the weight. Although the extraction temperature and the extraction time vary depending on the extraction solvent, for example, when dilute citric acid is used, it is desirable to perform extraction at 20 to 100 ° C for 0.5 to 6 hours, and for hydrous ethanol (ethanol concentration 20 to 70%). 20-60 ℃, 1 hour-2 weeks, water content 1,3-
Butylene glycol (1,3-butylene glycol concentration 20 ~
70%), it is desirable to extract at 20-100 ℃ for 1 hour-2 weeks.

[0010] The extracted seaweed extract can be used as it is, but when the solution is strongly acidic, it is desirable to adjust the pH. That is, it is preferable to adjust the pH to 3 to 8 with hydroxides such as sodium hydroxide and potassium hydroxide, ammonia and organic amines such as triethanolamine. The obtained seaweed extract is preferably further subjected to a purification step such as removal of insoluble matter by a step such as filtration and centrifugation. At that time, a chelating agent such as EDTA can be added as a stabilizer. The purified extract may be used as a solution as it is, or may be dried and used as a powder. Drying is performed by a heat drying method such as a freeze drying method and a spray drying method.

[0011] On the other hand, the seaweed powder is crushed after washing the calcified seaweed of the genus Akkeshishimo and / or Isimo. As the pulverization method, a generally used pulverization method may be used, and any pulverizer such as a rotary pulverizer and a ball mill can be used. The cosmetic containing the seaweed extract and / or seaweed powder prepared as described above is a lotion,
Milky lotion, beauty essence, face wash such as general cream, cleansing cream, pack, shaving cream, suntan cream, sunscreen cream, sunscreen lotion, suntan lotion, toilet soap, foundation, white powder, lipstick, lip balm, eyeliner,
Eye cream, eye shadow, mascara, bath cosmetics,
Examples include shampoos, conditioners, hair dyes, and hair cosmetics. The amount of the seaweed extract and seaweed powder added to the cosmetic is, for example, 0.001-100% in the cosmetic composition.
