It is a microscope image which shows the surface condition of the sample (hair) of Example 4 and Comparative Example 2 and the hair which has not been damaged.

Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments.

The hair quality improving composition according to one embodiment contains a distillate derived from sugar cane as an active ingredient. The sugarcane-derived distillate may be a distillation obtained by distilling at least one raw material selected from the group consisting of sugarcane juice and a solvent extract of sugarcane.

The term "improvement of hair quality" as used herein means, firstly, to improve the slipperiness of hair to give it a smooth feel. Improving the slippery feeling of the hair also improves the slippery feeling of the hair surface or reduces the roughness of the hair surface. "Improvement of hair quality" is secondly to give the hair a soft texture. Giving the hair a soft texture also means that the hair has less hardness when bent, and it is difficult for the hair to return to its original state after bending. The hair to be improved in hair quality may be hair before being damaged or hair after being damaged.

The sweet potato juice includes a pressed juice obtained by squeezing sugar cane, a leaching juice obtained by leaching the sugar cane with water, or a lime-treated clean juice and concentrated juice in a raw sugar manufacturing plant. The solvent extract of sugar cane means an extract obtained by extracting sugar cane with a general-purpose organic solvent.

The organic solvent for obtaining the sugarcane solvent extract may be alcohols such as methanol and ethanol, and two or more of these may be used in combination. Further, these organic solvents and water may be used in combination.

A sugarcane-derived distillate can be obtained in one embodiment by distilling at least one raw material selected from the group consisting of sugarcane juice and a solvent extract of sugarcane under the following conditions.

Distillation can be carried out, for example, at 50 ° C. to 120 ° C. at a pressure at which the liquid as a raw material boils. Distillation can preferably be carried out at 70 ° C. to 120 ° C. at a pressure at which the raw material liquid boils. The pressure may be appropriately adjusted depending on the solvent used for extraction, the apparatus used in the distillation step, and the like. For example, when water is used as the extraction solvent and distillation is performed using a centrifugal thin film vacuum evaporator, a flask connected to a cooling tube, or a distiller, the pressure is 240 mmHg to normal pressure at 70 ° C. to 105 ° C. May be. The distillation temperature may be, for example, 130 ° C. or lower. Distillation may be carried out at a temperature lower than the above range, but from the viewpoint of cost reduction, it is preferable to carry out distillation in the above temperature range. As the distillation apparatus, for example, a flask connected to a cooling pipe or the like may be used in a laboratory, and a concentrated can, a crystal can, a utility can or the like may be used in a factory.

For the purpose of further concentrating the active ingredient of the sugarcane-derived distillate obtained as described above, the distillate may be treated (passed through) by column chromatography using a fixed carrier. When processing by column chromatography, the distillate may be adjusted to an arbitrary concentration with water and then passed through the liquid. If the distillate contains alcohol, it may be diluted with water and then passed through column chromatography.

The fixed carrier is preferably a synthetic adsorbent. The synthetic adsorbent is preferably an organic resin, and may be, for example, an aromatic resin, an acrylic acid-based methacrylic resin, an acrylonitrile aliphatic resin, or the like. Commercially available products may be used as such synthetic adsorbents, for example, HP-10, HP-20, HP-21, HP-30, HP-40, HP-50 (or more, as Diaion ™ system). Non-replacement group type aromatic resin, all trade names, manufactured by Mitsubishi Chemical Corporation; SP-825, SP-800, SP-850, SP-875, SP-70, SP-700 (all of which are non-replacement). Aromatic resin with special treatment on the base, both trade name, manufactured by Mitsubishi Chemical Co., Ltd .; SP-900 (aromatic resin, trade name, manufactured by Mitsubishi Chemical Co., Ltd.); as Amberlite (trademark) , XAD-2, XAD-4, XAD-16, XAD-2000 (above, aromatic resins, all trade names are manufactured by Organo Co., Ltd.); , SP-207 (above, aromatic resin having a hydrophobic substituent, all trade names, manufactured by Mitsubishi Chemical Corporation); HP-2MG, EX-0021 (above, aromatic resin having a hydrophobic substituent). , All trade names, manufactured by Mitsubishi Chemical Co., Ltd.; HP1MG and HP2MG (above, acrylic acid-based methacrylic resin, both trade names, manufactured by Mitsubishi Chemical Corporation) as (trademark) systems; LH20, LH60 (above, derivatives of crosslinked dextran) as Sephadex (trademark) systems, both. A product name, Pharmacia Biotech Co., Ltd.) or the like may be used. The synthetic adsorbent can be appropriately selected depending on the concentration of the object to be passed through, the solvent, the extraction method, the coexistence, and the like.

The amount of the fixed carrier may be appropriately set depending on the size of the column, the type of the solvent, the type of the fixed carrier, and the like. For example, 1.5 to 20,000 times as much distillate as the fixed carrier can be passed through and the active ingredient can be adsorbed on the fixed carrier, that is, 1.5 to 20,000 of the distillate to be passed through. A one-third wet volume of fixed carrier can be used.

The amount and rate of liquid flow in the column chromatography treatment are appropriately adjusted depending on the method of distilling the distillation derived from sugar cane or the raw material selected from the sugar cane juice and the solvent extract of sugar cane. It's okay. After passing the distilled product through the column, the column may be washed with water to remove impurities to remove the components remaining in the column without being adsorbed by the resin.

By passing the distillate through the column, the components having a hair quality improving effect in the distillate are adsorbed on the fixed carrier. That is, the sugarcane-derived distillate according to the present embodiment is a column obtained by distilling at least one raw material selected from the group consisting of sugarcane juice and a solvent extract of sugarcane, using a fixed carrier. It may be a fraction obtained by processing by chromatography.

The fraction adsorbed on the fixed carrier can be eluted with a solvent. The solvent for elution may be at least one selected from water, methanol, ethanol and a mixture thereof, preferably a mixed solvent of water and alcohol, and more preferably a mixed solvent of ethanol and water. .. In order to efficiently elute the components having the desired effect at room temperature, the solvent is particularly preferably a 50/50 to 99.5 / 0.5 (volume / volume) ethanol-water mixed solvent. The elution rate is not particularly limited because it varies depending on the size of the column, the type of solvent, the type of fixed carrier, etc., but the eluate elutes at SV = 0.1 to 10 and elutes within 6 times the wet volume of the resin. It is preferable to recover. The SV (Space Velocity) is a unit of how many times the volume of the resin is passed per hour.

More specifically, the column chromatography treatment can be performed as follows, for example. That is, after passing a distillate through a column packed with an unsubstituted group type aromatic resin or acrylic acid ester resin at a column temperature of 60 to 97 ° C., the inside of the column is washed with water and then adsorbed on the column. The components are eluted with a 50/50 to 99.5 / 0.5 (volume / volume) ethanol-water mixed solvent at a column temperature of 20 to 40 ° C., and collected from the start of elution with the ethanol-water mixed solvent. Collect the eluate that elutes within 6 times the wet volume of the resin. This eluate can be used as a distillate derived from sugar cane in a hair quality improving composition.

The sugarcane-derived distillate can also be obtained by treating at least one raw material selected from sugarcane juice and a solvent extract of sugarcane by column chromatography and then distilling in another embodiment.

When at least one raw material selected from sweet potato juice and solvent extract of sweet potato is treated by column chromatography, the fixed carrier and liquid passing conditions are the same as those in the above-mentioned column chromatography treatment. It's okay. As the fixed carrier, it is preferable to use a fixed carrier having a wet volume of 0.01 to 5 times the solid content of the raw material.

Ingredients selected from sugar cane juice and sugar cane solvent extracts may be filtered prior to column treatment for foreign matter removal. The filtration method is not particularly limited, and means such as screen filtration, diatomaceous earth filtration, microfiltration, and ultrafiltration widely used in the food industry can be preferably used.

In still another embodiment, the sugarcane-derived distillate can also be obtained by distilling the raw material, treating it as a gas by column chromatography, and cooling it.

When the gas after distillation is subjected to column chromatography treatment, the fixed carrier is a porous adsorbent such as a zeolite-based adsorbent, activated charcoal, carbon black, alumina, or silica gel, a porous or fibrous adsorbent as a polymer adsorbent, and the like. It may be a ceramic-based porous adsorbent or the like.

As a method of column chromatography treatment in the present embodiment, for example, first, a column having a fixed carrier is connected to a steam outlet of a distillation apparatus, and steam is passed through the column. Then, the adsorbed component is recovered by applying a temperature higher than the temperature at the time of distillation to the column or by desorbing and recovering by reducing the internal pressure of the column. The temperature and pressure may be appropriately adjusted depending on the type of fixed carrier selected. The components obtained by the column chromatography treatment come out of the column as a gas, but can be cooled with a trap to make a liquid. The components adsorbed on the column can also be desorbed and recovered in the eluate by passing alcohols such as ethanol and methanol or other organic solvents through the column. The fraction or eluate thus obtained can be used as a distillate derived from sugar cane in a hair quality improving composition.

The composition for improving hair quality according to the present embodiment is suitably used as a hair cosmetic (hair cosmetic for improving hair quality). Hair cosmetics may be, for example, styling agents such as mousses, creams, gels, foams, sprays and mists, shampoos, conditioners, conditioners, treatments, hair dyes and the like.

The content of the sugarcane-derived distillation contained in the hair quality improving composition may be an effective amount for improving the hair quality, and may be appropriately set depending on the type of hair cosmetic.

From the viewpoint of improving the slipperiness of the hair, the content of the distillate derived from sweet potato in one embodiment may be preferably 0.003% by mass or more based on the total amount of the composition for improving the hair quality, and more. It may be preferably 0.005% by mass, more preferably 0.01% by mass or more, preferably 1% by mass or less, and more preferably 0.5% by mass or less. It may be more preferably 0.1% by mass or less.

From the viewpoint of giving the hair a soft texture, the content of the distillate derived from sweet potato in one embodiment may be preferably 0.0005% by mass or more based on the total amount of the composition for improving hair quality, which is more preferable. May be 0.0007% by mass or more, more preferably 0.001% by mass or more, preferably 0.7% by mass or less, and more preferably 0.5% by mass or less. It may be 0.1% by mass or less, more preferably 0.1% by mass or less.

The composition for improving hair quality may contain other components generally used in hair cosmetics in addition to the distillate derived from sugar cane. Other components include, for example, oily components, surfactants (synthetic and natural products), moisturizers, thickeners, preservatives / bactericides, powder components, ultraviolet absorbers, antioxidants, pigments, fragrances, etc. Can be mentioned.

The method of improving the hair quality by using the hair quality improving composition (hair cosmetic) according to the present embodiment may be a method of applying the above-mentioned hair quality improving composition to the hair. Specifically, the composition may be applied to the hair (or damaged hair) and adhered by spraying or the like, and in some cases, the composition may be adhered to the hair and then washed away. .. As a result, the slippery feeling of the hair can be improved to give a smooth feel and a soft texture to the hair.
