Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair and, more particularly, to a cosmetic for hair which has no irritation and is excellent in imparting gloss and smoothness to hair.

[0002]

2. Description of the Related Art Olive fruits are about 15 to 30% by mass (hereinafter simply referred to as%).
Contains about 70% of water together with the lipid components. The olive oil obtained by pressing the olives (Olea europaea Linne) contains about 25% solid glycerides composed of stearic acid and palmitic acid, and about 75% liquid glycerides such as linoleic acid and oleic acid. It has been widely used for edible oils, cosmetics, soap ingredients, medicinal products, etc. since ancient times. A large amount of water called vegetation water is produced in the process of producing olive oil.
In other words, it is an aqueous part obtained by pressing olive berries, and it is known that about 1% of polyphenols are contained together with about 3% of sugars, about 1% of organic acids, and about 1% of lipids. Have been. However, this vegetation water is an unnecessary substance and a waste in the olive oil production process, and its application has hardly been studied.

The present inventors have conducted intensive studies on the application of vegetation water. As a result, the addition of vegetation water has no irritation and is excellent in imparting gloss and smoothness to hair. It was confirmed that a hair cosmetic was obtained, and the present invention was completed.

[0004] That is, an object of the present invention is to provide a hair cosmetic composition which has no irritation and is excellent in imparting gloss and smoothness to hair.

[0005]

The above object is achieved by containing vegetation water produced in the process of producing olive oil. That is, the present invention resides in a hair cosmetic comprising vegitation water produced in the process of producing olive oil.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As the vegetation water used in the present invention, it is possible to directly use an aqueous solution produced in the process of obtaining ordinary olive oil. It is preferable that the shells and the like are removed and purified by filtration or centrifugation before use. Further, for the purpose of suppressing the generation of offensive odor or the like due to the contamination of various bacteria, it is also possible to add alcohols to the aqueous solution and then separate and purify by adding filtration or centrifugation. Further, the obtained vegetation water can be used after being concentrated or dried by an ordinary method.

The method for producing an organic solvent extract of vegetation water in the present invention will be described. As the extraction method,
First, the vegetation water is washed several times at room temperature with a non-polar solvent such as n-hexane, benzene, and chloroform to remove fat-soluble substances and the like in the raw material. next,
From the vegetation water obtained in the above step, a target solvent extract is extracted at room temperature with diethyl ether, ethyl acetate, acetone, methanol, ethanol or the like. The solvent used in the above extraction step may be used as a mixture of two or more kinds. The obtained solvent extract is dried over magnesium sulfate (anhydrous), sodium sulfate, or the like, and filtered, and then the solvent is completely distilled off at 30 ° C. or lower before use. The obtained extract can be used by dissolving and dispersing it in ethanol or the like. The extract thus obtained has an excellent antioxidant activity and the like, and can be used for skin external preparations, hair cosmetics, foods, and the like.

[0008] The cosmetic for hair characterized by containing the vegetation water or an organic solvent extract thereof according to the present invention is generally used in hair cosmetics, if necessary, as long as its effect is not impaired. Various components such as oils, silicones, surfactants, humectants, thickeners, preservatives, antioxidants, ultraviolet absorbers, fragrances, pigments, sugars, salts, polyhydric alcohols, vitamins, amino acids, etc. They can be combined and combined. Further, the cosmetic for hair according to the present invention includes a pre-shampoo, a shampoo, a hair rinse,
Hair conditioner, hair treatment, set lotion, blow styling lotion, hair spray, foam styling agent, hair liquid, hair cream, hair colon, permanent wave agent, pre-permanent agent, permanent hair dye, one hair dye, Hair restorer,
Can be used as an anti-dandruff agent, etc., aqueous solution, ethanol solution, emulsion, suspension, gel, liquid crystal,
An arbitrary mold such as a solid or an aerosol can be used.

The amount of the above-mentioned vegetation water or its organic solvent extract to be incorporated into the cosmetic for hair of the present invention varies widely depending on the purpose and the dosage form of the cosmetic for hair and cannot be specified unconditionally. But generally 0.001 in terms of dry matter
Is preferably from 10 to 10%, particularly preferably from 0.01 to 5%. If it is less than 0.001%, the effect of imparting gloss and smoothness to the hair may be insufficient, and even if it exceeds 10%, the effect corresponding to the amount may not be obtained.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

Example 1 Production example of vegetation water 2 liters of undenatured ethanol was added to 8 liters of an aqueous solution produced in a usual olive oil production process. The obtained aqueous ethanol solution was heated at 4 ° C. at a rotation speed of 10,000 rpm.
For about 15 minutes to separate into about 1.5 kg of solid matter and about 8.5 liters of aqueous layer. The obtained vegetation water was filtered through celite according to a conventional method to obtain about 8.5 liters of pale yellow vegetation water.

Example 2: Production example of dried vegetation water 5 g of vegetation water obtained in Example 1 was freeze-dried to obtain about 220 g of dried vegetation water.
Obtained.

Example 9 (Antioxidant power test) The antioxidant power of the organic solvent extract of the vegetation water of Example 8 was tested. The lipid peroxidation was performed using a medical ultraviolet irradiator M-DMR manufactured by Toshiba, and after irradiating UVB waves, the degree of lipid peroxidation of each sample was measured. As a method for measuring the degree of lipid peroxidation, the fluorescence intensity of DPPP (diphenyl-1-pyrenylphosphine) was measured with a fluorometer (λex 352 nm, λem 380 nm). For the test, 0.001 m of the test sample was added to methyl linoleate.
The comparison was carried out with the addition of mol / g, and the peroxidation rate of the unadded methyl linoleate was 100%. As a comparative object, BHT (butylhydroxytoluene) which is a known antioxidant was used. As a result, as shown in FIG. 1, it was confirmed that the organic solvent extract of the vegetation water used in the present invention had excellent antioxidant power.
