Description

  The present invention relates to a hair dye composition using a dyeable plant powder such as henna or indigo, and a hair dyeing method using the same.

  In recent years, p-phenylenediamine type or aminophenol type oxidation dyes, which are synthetic dyes, have been widely used as dye components of hair dye compositions. This is because such an oxidative dye has excellent hair dyeing power and can express various color tones, thereby meeting various requirements.

  However, oxidative dyes are known to cause skin damage. In addition, there are indications that it is an environmental hormone that adversely affects the ecosystem, and that there are suspicions such as carcinogenicity and allergenicity. For this reason, hair dyeing using oxidative dyes is partially regulated in Europe and the like.

  From such a viewpoint, direct dyes such as HC dyes and basic dyes, which are considered to be safer than oxidative dyes, are also used as the dye component of the hair dye composition. Hair dyes using direct dyes, unlike ordinary oxidative hair dyes, can be dyed in the neutral range, so there is no damage to the hair due to alkali, and oxidants such as hydrogen peroxide. Is unnecessary, there is no risk of accidents caused by skin irritation and eye contact, and it is a relatively safe hair dye. For example, since HC dye is a dye having a small molecular diameter, it is dyed by hydrogen bonding or intermolecular attractive force at a relatively inner layer inside hair. Further, since the basic dye has a large molecular diameter and a positive charge in the molecular structure, it is dyed by ionic bonding with the minus part of the keratin protein on the hair surface. These direct dyes are not damaged even if they are repeatedly dyed in order to dye the hair without chemical reaction. However, there is a drawback that the dyeing effect is not long-lasting and the color fading easily due to repeated shampooing.

  On the other hand, in recent years, dyeable plant powders containing vegetable dyes such as henna dyes have attracted attention. Henna dye is an orange to brown natural dye obtained by drying and pulverizing the leaves of Lawsoniainermis, which is a shrub of the family Lamiaceae from India, Iran and other tropical regions. Henna dye contains 2-hydroxy-1,4-naphthoquinone (also called Lawsone) as an active ingredient, and Lawson is mainly concentrated in leaves.

For example, Patent Document 1 listed below discloses a hair dye thickener comprising powdered henna, and also discloses a hair dye composition in which a dye is directly blended with powdered henna.
JP 2002-284654 A

  Since the dyeable plant powder is a natural dye as described above, it is considered to be safer than the synthetic dye, and it is said to have a relatively long color compared to the direct dye. However, hair dyeing using dyeable plant powder has a problem that it takes time to sufficiently develop color. For example, in the case of hair dyeing using a hair dye composition containing henna powder as a main component, a paste in which henna powder is dissolved is usually applied to the hair, and then the human body is not burdened by a heating device. After leaving at a temperature of about ~ 35 ° C for about 10 to 30 minutes, shampooing and finishing are performed to finish the treatment. When a conventional hair dye composition containing henna powder as a main component is used, sufficient color development cannot be obtained immediately after this treatment. Therefore, usually, it can be confirmed that a finished color is obtained several days after the treatment. Therefore, for example, when hair is dyed in a beauty salon, the finished color cannot be confirmed immediately after the treatment, and the person to be treated can leave the hair salon without sufficiently coloring the hair. I couldn't get enough satisfaction from the treatment to do later.

  The present invention relates to a hair dyeing composition that enables coloration of a sufficiently finished color immediately after treatment in hair dyeing using a henna dye, and a hair dyeing method using the composition.

  The hair dye composition of the present invention contains 0.5 to 10 parts by mass of thermally conductive inorganic particles having a thermal conductivity of 5 W / mK or more with respect to 100 parts by mass of the dyeable plant powder. According to this configuration, since the heat conductive inorganic particles have an action of storing heat, the hair to which the paste of the hair dye composition is applied can be effectively warmed in the heating stage in the treatment. Thereby, color development proceeds in a short time and a color close to the finished color is obtained. This mechanism is not clear at this time. However, the inventor thinks as follows from the accumulated experimental results. That is, when hair is dyed using a dyeable plant powder, after the dyeable plant powder has penetrated into the hair, the polyphenols, which are pigment components contained in the dyeable plant powder, bind to the hair and leave the hair. It seems that it becomes difficult to come off and the color is sufficiently developed by the progress of the chemical reaction. Here, it is considered that, by blending thermally conductive inorganic particles with the dyeable plant powder, heat does not diffuse in the heating stage, and the chemical reaction proceeds in a short time by efficiently warming the hair.

  Examples of the thermally conductive inorganic particles include aluminum oxide, titanium oxide, magnesium oxide, zinc oxide, iron oxide, zirconium oxide, silicon oxide, boron nitride, aluminum nitride, silicon nitride, magnesium oxide, beryllium oxide, apatites, In addition, the particles are preferably particles of at least one compound selected from the group consisting of silicon carbide. Since these inorganic particles have high thermal conductivity, the effect of promoting color development is high.

  Moreover, it is preferable to contain further 0.1-10 mass parts of direct dyes with respect to 100 mass parts of said dyeable plant powders. Since the direct dye is adsorbed to the hair without passing through a covalent bond, it has a defect that it is poor in fixing property and easily loses its color due to shampoo or the like. However, according to the present invention, the direct dye is difficult to lose its color. This is considered that the polyphenol in the dyeable plant powder has some action for directly immobilizing the dye.

  In addition, the hair dyeing method of the present invention comprises a step of adding water to the hair dye composition described above to prepare a paste, a step of applying the paste to the hair, and a hair surface temperature of 30 to 40 ° C. It is characterized by comprising a step of leaving for 10 to 30 minutes while maintaining heating, a step of washing away excess paste attached to the hair by washing, and a step of drying the hair. According to this configuration, since the hair is efficiently warmed by the heat conductive inorganic particles during the heat treatment, a color close to the finished color can be obtained in a relatively short time.

  Moreover, it is preferable to further include a step of pressing the dried hair with an iron press controlled at a surface temperature of 150 to 200 ° C. According to such a process, the chemical reaction of the dye component in the dyeable plant powder can be almost terminated by the iron press for processing at high temperature and high pressure. Therefore, for example, the finished color can be confirmed immediately after the treatment. Further, since the chemical reaction can be almost terminated immediately after the treatment, even when shampooing is performed several hours after the treatment, the loss of the dye is reduced.

  ADVANTAGE OF THE INVENTION According to this invention, in the hair dyeing using dyeable plant powder, the composition for hair dyeing and the hair dyeing method in which color development of sufficient finished color is possible immediately after hair dyeing treatment can be provided.

  The composition for hair dyeing of the present invention contains 0.5 to 100 parts by mass of thermally conductive inorganic particles having a thermal conductivity of 5 W / mK or more with respect to 100 parts by mass of the dyeable plant powder. The present invention will be described in detail below.

  Examples of the dyeable plant powder used in the present invention include henna powder, natural indigo, turmeric, walnut shell, tea leaf, rose, persimmon leaf, coffee seed, lemon peel and the like. These may be used alone or in combination of two or more.

  In addition, for example, henna powder is obtained by drying henna leaves and stems, which are shrubs of the family Lamiaceae known by scientific names such as Lawsonia inermis, Lawsonia alba Lam. . Henna powder contains 2-hydroxy-1, 4-naphthoquinone (Lawson) and polyphenols. Natural indigo is preferable from the viewpoint of excellent color balance.

  The hair dye composition of the present invention contains thermally conductive inorganic particles. For this reason, the hair to which the paste of the composition for hair dyeing was apply | coated can be heated effectively at the time of the heat processing in a hair dyeing process. Thereby, the finished color of dyeing can be obtained in a relatively short time. This is because when hair is dyed with a dyeable plant powder, the chemical reaction of the polyphenol component, which is a pigment component contained in the vegetable dye, proceeds in a short time due to heat storage of the heat conductive inorganic particles. thinking.

As such heat conductive inorganic particles, any inorganic particles having a heat conductivity of 5 W / mK or more and excellent in heat conductivity can be used without particular limitation. Specific examples thereof include, for example, aluminum oxide, titanium oxide, magnesium oxide, zinc oxide, iron oxide, zirconium oxide, silicon oxide, boron nitride, aluminum nitride, silicon nitride, magnesium oxide, beryllium oxide, apatites, and carbonization. Silicon etc. are mentioned. As the particle diameter of the thermally conductive inorganic particles, those having an average particle diameter (D50) of 0.5 to ₅₀ [mu] m, 1 to 30 [mu] m, particularly 1 to 10 [mu] m are preferably used.

  As a compounding quantity of a heat conductive inorganic particle, it is 0.5-100 mass parts with respect to 100 mass parts of dyeable plant powder, Preferably it is 1-10 mass parts. When the blending ratio of the heat conductive inorganic particles is less than 0.5 parts by mass with respect to 100 parts by mass of the dyeable plant powder, a sufficient color-promoting effect cannot be obtained, and when it exceeds 100 parts by mass , Hair dyeing workability deteriorates.

  In the present invention, as a dye component, other dyes such as a direct dye, a basic dye, and an HC dye may be blended so as to adjust the color tone without impairing the effects of the present invention. In addition, according to this invention, the color fading of the other dye used together with a henna dye can also be suppressed. This is thought to be because the polyphenol in the henna dye polymerizes and crosslinks at a relatively fast stage, so that other dyes are fixed and are not easily removed by the shampoo after the treatment.

  Specific examples of other dyes include, for example, 2,2′-bis (2,3-dihydro-3-oxoindolilidene), indigotine, nitro-p-phenylenediamine, p-nitro-o-phenylenediamine, p-nitro-m-phenylenediamine, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol, picramic acid, N1, N4, N4-tris (2-hydroxyethyl) -2-nitro-p- Phenylenediamine, 4-[(2-nitrophenyl) amino] phenol, N1- (2-hydroxyethyl) -2-nitro-p-phenylenediamine, 2,2 ′-[(4-amino-3-nitrophenyl) Imino] bisethanol, N- (2-hydroxyethyl) -2-nitroaniline, 2-[[2- (2-hydroxyethoxy) -4-nitrophenyl] Mino] ethanol, N1- (2-hydroxyethyl) -4-nitro-o-phenylenediamine and salts thereof, 1,4-diaminoanthraquinone, “Ministerial ordinance for determining tar dyes that can be used in pharmaceuticals” (Showa) 41 (hereinafter referred to as Ministry of Health and Welfare) dyes (hereinafter abbreviated as legal pigments), that is, legal pigments Red No. 2, Red No. 3, Red No. 102, Red No. 104 (1), Red No. 105 (1) Red 106, Red 201, Red 218, Red 225, Red 227, Red 230 (1), Red 230 (2), Red 231, Red 232, Red 401, Red 501, red 502, red 503, red 504, red 505, red 506, orange 201, orange 205, orange 207, orange 4 No. 02, orange No. 403, yellow No. 4, yellow No. 5, yellow No. 201, yellow No. 202 (1), yellow No. 202 (2), yellow No. 203, yellow No. 204, yellow No. 402, yellow 403 No. (1), yellow 404, yellow 405, yellow 406, yellow 407, blue 1, blue 2, blue 201, blue 202, blue 203, blue 205, blue 403, Green No. 3, Green No. 201, Green No. 202, Green No. 205, Green No. 401, Green No. 402 A Brown 201, Purple 201, Purple No. 401 and Black No. 401, and International Cosmetic Ingredient Dictionary and Handbook Basic Blue 3, Basic Blue 7, BasicBlue 9, Basic Blue 26, Basic Blue 47, Basic Blue 99, Basic Brown 4, Basic Brown 16, Basic Brown 17, Basic Green listed in Eighth Edition (issued by US CTFA) 1, Basic Green 4, Basic Orange 1, Basic Orange 2, Basic Red 1, Basic Red 2, Basic Red 22, Basic Red 46, Basic Red 76, Basic Red 118, Basic Violet 1, Basic Violet 3, Basic Violet 4, Basic Violet 10, Basic Violet 11: 1, Basic Violet 14, Basic Violet 16, Basic Yellow 28, Basic Yellow 57, Direct Black 51, Direct Red 23, Direct Red 80, Direct Red 81, Direct Violet 48, Direct Yellow 12, DisperseBlack 9, Disperse Blue 1, Disperse Blue 3, Disperse Blue 7, Disperse Brown 1, Disperse Orange 3, Disperse Red 11, Disperse Red 15, Disperse Red 17, Disperse Violet 1, Disperse Violet 4, Disperse Violet 15, HC Blue No.2, HC Blue No.4 , HC Blue No.5, HC Blue No.6, HC Blue No.7, HC Blue No.8, HC Blue No.9, HC Blue No.10, HC Blue No.11, HC Blue No.12, HC Blue No.13, HC Blue No.14, HC Brown No.1, HC Brown No.2, HC Green No.1, HC Orange No.1, HC Orange No.2, HC Orange No.3, HC Orange No .5, HC Red No.1, HCRed No.3, HC Red No.7, HC Red No.8, HC Red No.9, HC Red No.10, HC Red No.11, HC Red No.13, HC Red No.14, HC Violet No.1, HC Violet No.2, HC Yellow No.2, HC Yellow No.4, HC Yellow No.5, HC Yellow No .6, HC Yellow No. 7, HC Yellow No. 8, HC Yellow No. 9, HC Yellow No. 10, HC Yellow No. 11, HC Yellow No. 12, HC Yellow No. 13, HC Yellow No. 14 HC Yellow No. 15, Solvent Black 3, Solvent Black 5, Solvent Blue 35, Solvent Yellow 172, and the like. Among these, HC dyes, which are specific examples as dyes having “HC” as a prefix, are particularly preferable because they penetrate into the hair and give a deeper color. A basic dye is preferred from the viewpoint of excellent dyeability stability. Furthermore, a combination of a basic dye and an HC dye is particularly preferable from the viewpoint of performing oxidation type dye polymerization.

  When mix | blending HC dye and a basic dye, it is preferable to mix | blend 0.5-5 mass parts with respect to 100 mass parts of dyeable plant powder, respectively, Furthermore, 1-2 mass parts is blended. By blending at such a ratio, color fading can be sufficiently suppressed.

  Next, the method for dyeing hair using the above-described hair dye composition will be described in detail.

  In dyeing hair, first, a paste is prepared by adding water to the hair dyeing composition. The amount of water to be blended in the hair dyeing composition is not particularly limited as long as it is an amount capable of obtaining a paste having a viscosity that does not sag excessively when applied to hair. Specifically, for example, the amount is preferably 0.8 to 5 times, more preferably about 1 to 3 times the total amount of the hair dye composition. Then, the prepared paste is applied to the hair, and the hair is wrapped with a resin film or the like. And it heats so that hair surface temperature may become about 30-40 degreeC with a far-infrared heater etc., and it maintains for 10 to 30 minutes as it is. After the color check, the excess paste attached to the hair is washed away. By such a process, the chemical reaction of the dye in the dyeable plant powder can be advanced in a short time. Therefore, for example, immediately after the treatment, color development closer to the finished color can be obtained in a shorter time than in the past. Further, since the thermally conductive inorganic particles promote the progress of the chemical reaction, the color fading due to shampoo after the treatment is reduced.

The hair dyeing method of the present invention further comprises a step of pressing the hair after dyeing and drying with a hair iron press having a surface temperature in the range of 150 to 200 ° C, preferably 160 to 180 ° C. Is preferred. According to such a process, the chemical reaction of the henna powder can be almost terminated for processing at the high temperature and high pressure of the iron press. Therefore, for example, the finished color can be confirmed immediately after the treatment. Further, since the chemical reaction can be almost terminated immediately after the treatment, even when shampooing is performed several hours after the treatment, the loss of the dye is reduced.

  In addition, it is known that the polyphenols contained in the dyeable plant powder are easily denatured under light irradiation conditions and the reaction activity is reduced. Therefore, for example, immediately after receiving a hair dyeing treatment by a beauty salon, the reaction does not proceed sufficiently, and thus the reaction activity of unreacted polyphenols is reduced by light from the external environment. And there exists a possibility that unreacted modified polyphenols may be washed away by the hair wash of a to-be-treated person. According to the present invention, since it is possible to almost completely terminate the chemical reaction immediately after the treatment, the polyphenols which are the active ingredients of the dye in the dyeable plant powder even if the subject himself hashes his hair several hours after the treatment Is also prevented from being washed away.

  Hereinafter, the present invention will be described in more detail with reference to examples. It should be noted that the scope of the present invention is not limited in any way by this example.

  Dyeing plant powder (henna powder and natural indigo powder manufactured by Kirpal Co., Ltd.), basic dye (Basic Brown No.17), HC dye (HC Yellow No.2, HC Red No.1), heat A conductive inorganic filler (aluminum oxide or titanium oxide) was mixed in the amounts shown in Table 1 to prepare a hair dye composition, and water was further added to prepare a paste.

  Next, each prepared paste was applied to a hair bundle made of human hair having a total weight of 10 g bound at one end. In addition, all the human hair which comprises a hair bundle was white hair.

  Then, after wrapping the hair bundle to which the paste was applied, the far-infrared warmer was set at 40 ° C. and maintained for about 30 minutes. At this time, the temperature of the human hair surface was about 40 ° C. And the paste adhering to the hair bundle was washed away with water and further washed with a commercially available shampoo agent. And after wiping off moisture with a towel well, it dried with the dryer to such an extent that there was no moisture. The color tone immediately after drying was visually evaluated.

  Further, the hair bundle after drying was hot-pressed for about 5 seconds using a hair iron press set at 180 ° C. And the color tone after hot press was evaluated visually.

  In addition, the said color tone evaluation was determined based on the JIS conventional color name based on the following criteria.

  The results are shown in Table 1.

  The hair bundles dyed with the dyes of Examples 1 to 4, which contain henna powder, natural indigo powder, basic dye, and thermally conductive inorganic particles, show a dark yellow-brown color immediately after drying with a dryer. It was. And after drying with a dryer, when further ironing, it showed dark black-brown color immediately after the ironing. The color development after the iron press was equivalent to the color development when the same sample was dried and left for one week without iron pressing. On the other hand, the dyed hair bundles obtained in Comparative Examples 1 and 2 dyed with a paste containing no inorganic filler showed a light yellow color tone immediately after drying with a dryer. Then, the density gradually increased over time, and the color became stable when one week passed. However, the color developed at that time was brown, and did not reach the dark brown color of Examples 1 to 4.

  In addition, the hair bundle dyed with the dyes of Examples 5 to 7, in which only the henna powder and natural indigo powder are used as dyes and the heat conductive inorganic particles are blended without using the basic dye, is yellow immediately after drying with a dryer. Showed the color tone. And after drying with a drier, when further ironing, it showed dark brown color immediately after the ironing. The color development after the iron press was equivalent to the color development when the same sample was dried and left for one week without iron pressing. On the other hand, the dyed hair bundles obtained in Comparative Examples 3 and 4 dyed with a paste containing no inorganic filler in the same dyeing system showed a yellow color immediately after drying with a dryer. Then, the density gradually increased over time, and the color became stable when one week passed. However, the color development at that time was reddish brown, and did not reach the darkness of Examples 5-6.

  When hair is dyed using the hair dye composition according to the present invention, the desired finish color can be obtained in a short time. Therefore, for example, when a hair dyeing operation is performed in a beauty salon, satisfaction can be given to the person to be treated.
