  That is, the present invention is a powdery artificial hair thickener containing (A) a pine bark extract and (B) a bark extract.

The powdery pseudo hair thickener of the present invention is excellent in gloss and gloss when applied to hair, and can prevent hair pain due to ultraviolet irradiation.
Moreover, since the pseudo hair thickener of the present invention has a high hair fixing property, it has a natural and uniform finish, and has a high effect of making the thinned portion of the hair inconspicuous.

  The present invention is a powdery pseudo hair thickener containing (A) a pine bark extract and (B) a bark extract. The pseudo hair thickener is also called a hair foundation or a hair powder. Details will be described below.

(Pine bark extract)
Examples of the pine bark that can be used in the pine bark extract (A) in the present invention include, for example, French coastal pine, larch, black pine, red pine, Japanese pine, Japanese pine, Korean pine, high pine, Ryukyu pine, Utsukushima, Japanese pine, and white pine. Bark of plants belonging to the order of Pinae, such as Aneda in Quebec, Canada.
Among these, the bark of French coastal pine (scientific name: Pinus maritima) is preferable, and the French coastal pine refers to marine pine grown on the Atlantic coast of southern France. When the French coastal pine bark extract is used, the gloss, glossiness and hair stickiness when used in combination with the (B) cream extract described later are enhanced. Moreover, the effect | action which accelerates | stimulates the proliferation effect and hair growth of a dermal papilla cell by the blood-flow improvement effect is also expectable.

  The pine bark extract is obtained by extracting the pine bark with a solvent. Examples of the solvent that can be used here include water, organic solvents, and hydrous organic solvents (hydrous alcohols such as hydrous ethanol). When water is used as a solvent, warm water or hot water may be used. As an organic solvent used for extraction, an organic solvent that is acceptable for the production of foods or drugs is used. For example, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, butane, acetone, hexane , Cyclohexane, propylene glycol, hydrous ethanol, hydrous propylene glycol, ethyl methyl ketone, glycerin, methyl acetate, ethyl acetate, diethyl ether, dichloromethane, edible fats and oils, 1,1,1,2-tetrafluoroethane, and 1,1, 2-trichloroethene is mentioned.

As the supercritical fluid, carbon dioxide, ethylene, propane, nitrous oxide (laughing gas) or the like is used, and carbon dioxide is preferably used.

  In the supercritical fluid extraction method, an extraction process for extracting a target component with a supercritical fluid and a separation process for separating the target component and the supercritical fluid are performed. In the separation step, any one of extraction separation by pressure change, extraction separation by temperature change, and extraction separation using an adsorbent / absorbent may be performed.

  Moreover, you may perform supercritical fluid extraction by the entrainer addition method. In this method, for example, ethanol, propanol, n-hexane, acetone, toluene, other aliphatic lower alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, and ketones are added to the extraction fluid in an amount of 2 to 20 W / V. %, And by performing supercritical fluid extraction using this fluid, the solubility of the target extract such as OPC (oligomeric proanthocyanidin) and catechins in the extraction solvent is dramatically increased. Or a method for enhancing the selectivity of separation, and obtaining an efficient pine bark extract.

  Since the supercritical fluid extraction method can be operated at a relatively low temperature, it can be applied to substances that are altered or decomposed at high temperatures, the advantage that the extraction fluid does not remain, and the recycling of the solvent is possible. There is an advantage that the process can be omitted and the process becomes simple.

  Extraction from pine bark may be performed by a liquid carbon dioxide batch method, a liquid carbon dioxide reflux method, a supercritical carbon dioxide reflux method, or the like, in addition to the extraction method described above.
