Description

Technical Field

[0001] The present invention relates to a hair dye composition used in hair dyeing treatment.

Background Art

[0002] Conventionally, as a hair dye for dyeing hair, a hair dye using a basic dye has been used. This hair dye using a basic dye can solve safety problems such as allergies caused by oxidative hair dyes, avoid damage to hair and scalp caused by strong alkaline agents and hydrogen peroxide, and can also impart stiffness and firmness to hair. Therefore, it is widely used for hair care and gray hair dyeing.

[0003] As such a hair dye composition, for example, a hair dye composition containing at least one selected from the group consisting of thioglycolic acid, 3-mercapto-1,2-propanediol, cysteamine, and salts thereof, sodium hydroxymethanesulfinate, a basic dye, HC dye, etc., and having a pH of 6.8 to 10 has been proposed. And it is described that damage to the scalp can be reduced by such a configuration (for example, see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above-described conventional hair dye composition, direct dyes such as basic dyes and HC dyes adhere to the skin (scalp and fingertips), making it difficult to remove the direct dyes from the skin. Therefore, in order to suppress the adhesion to the skin, it is necessary to lower the concentration of the dye in the hair dye composition. As a result, there has been a problem that the dyeability with respect to the hair decreases, and it becomes difficult to obtain a visually recognizable vivid color development.

[0006] Also, generally, from the viewpoints of reducing environmental impact and low cost, etc., an aluminum container (for example, an aluminum tube) is used as a container for filling the hair dye composition. However, from the viewpoint of improving the dyeability in a low-concentration dye, alcohol (for example, ethanol) is used as a penetrant. However, when using a penetrant, there has been a problem that the penetration (that is, adhesion) of the dye to the skin is also promoted, and deformation such as corrosion and expansion occurs in the aluminum container.

[0007] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a hair dye composition that can obtain a visually recognizable vivid color development, can suppress adhesion to the skin, and can suppress deformation such as corrosion and expansion of an aluminum container filled with the hair dye composition.

Means for Solving the Problems

[0008] In order to achieve the above object, the hair dye composition of the present invention contains, as component (A), at least one basic dye selected from the group consisting of Basic Red 51, Basic Red 76, Basic Orange 31, Basic Yellow 57, Basic Yellow 87, Basic Blue 99, Basic Blue 124, Basic Violet 2, Basic Brown 16, Basic Brown 17, and Red 213, contains, as component (B), at least one HC dye selected from the group consisting of HC Yellow 4, HC Blue 2, HC Blue 12, and HC Blue 16, contains, as component (C), at least one of a sugar alcohol having 6 to 12 carbon atoms and a polyhydric alcohol having 3 to 5 carbon atoms, contains, as component (D), at least one of a monohydric alcohol having 2 to 8 carbon atoms and an aromatic alcohol having 6 to 8 carbon atoms, the content of component (D) is less than 10% by mass, and the pH is 3 to 7.

Effect of the Invention

[0009] According to the present invention, a visually recognizable vivid color development can be obtained, and the dyeing on the fabric can be suppressed. In addition, deformation such as corrosion and expansion of the aluminum container filled with the hair dye composition can be suppressed.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, preferred embodiments of the present invention will be described. It should be noted that the present invention is not limited to the following embodiments, and can be appropriately modified and applied without changing the gist of the present invention.

[0011] The hair dye composition of the present invention contains a basic dye and an HC dye, and is used in hair dyeing treatments such as white hair dyeing and hair manicure.

[0012] (Basic Dye) The hair dye composition of the present invention contains, as a basic dye (hereinafter sometimes referred to as component (A)), at least one selected from the group consisting of Basic Red 51, Basic Red 76, Basic Orange 31, Basic Yellow 57, Basic Yellow 87, Basic Blue 99, Basic Blue 124, Basic Violet 2, Basic Brown 16, Basic Brown 17, and Red 213.

[0013] In addition, the content of component (A) in the whole dyeing material composition of the present invention is preferably 0.001% by mass or more and 0.02% by mass or less out of 100% by mass of the dyeing material composition. This is because when it is less than 0.001% by mass, the color development may be weak and the color saturation may be low, and when it is more than 0.02% by mass, it may be difficult to effectively suppress the dyeing on the fabric.

[0014] (HC dye) The dyeing material composition of the present invention contains at least one selected from the group consisting of HC Yellow 4, HC Blue 2, HC Blue 12, and HC Blue 16 as an HC dye (hereinafter sometimes referred to as component (B)).

[0015] In addition, the content of component (B) in the whole dyeing material composition of the present invention is preferably 0.005% by mass or more and 0.5% by mass or less out of 100% by mass of the dyeing material composition. This is because when it is less than 0.005% by mass, the color development may be weak and the color saturation may be low, and when it is more than 0.5% by mass, it may be difficult to effectively suppress the dyeing on the fabric.

[0016] (Sugar alcohol, polyhydric alcohol) The dyeing material composition of the present invention contains at least one of a sugar alcohol having 6 to 12 carbon atoms and a polyhydric alcohol having 3 to 5 carbon atoms as component (C) as a penetrant.

[0017] Examples of the sugar alcohol include sorbitol (6 carbon atoms), mannitol (6 carbon atoms), and maltitol (12 carbon atoms). These can be used alone or in combination of two or more.

[0018] Examples of the polyhydric alcohol include propylene glycol (3 carbon atoms), 1,3-butylene glycol (4 carbon atoms), 3-methyl-1,3-butanediol (4 carbon atoms), and 1,2-pentanediol (5 carbon atoms). These can be used alone or in combination of two or more.

[0019] By using the component (C), the affinity between the hair dye composition and the hair is improved and the dyeing power is enhanced, so that a visually recognizable vivid color development can be obtained.

[0020] From the viewpoint of improving the permeability of the dye into the hair and surely obtaining a visually recognizable vivid color development, the content of the component (C) in the whole hair dye composition is preferably 5% by mass or more and 15% by mass or less.

[0021] (Monohydric alcohol, aromatic alcohol) The hair dye composition of the present invention contains, as another penetrant, at least one of a monohydric alcohol having 2 to 8 carbon atoms and an aromatic alcohol having 6 to 8 carbon atoms as the component (D). This component (D) has a role of complementing the penetration action of the above-mentioned component (C).

[0022] Examples of the monohydric alcohol having 2 to 8 carbon atoms include ethanol (2 carbon atoms), 1-propanol (3 carbon atoms), 2-propanol (3 carbon atoms), and 1-butanol (4 carbon atoms). These can be used alone or in combination of two or more.

[0023] Examples of the aromatic alcohol having 6 to 8 carbon atoms include benzyl alcohol (7 carbon atoms), phenethyl alcohol (8 carbon atoms), and phenoxyethanol (8 carbon atoms). These can be used alone or in combination of two or more.

[0024] Further, when the content of component (D) is high, the penetration (i.e., dyeing) of the dye into the base fabric is promoted, and deformation such as corrosion and swelling of the aluminum container filled with the dyestuff composition occurs. Therefore, from the viewpoint of reliably suppressing the dyeing onto the base fabric and reliably suppressing deformation such as corrosion and swelling of the aluminum container, the content of component (D) in the whole dyestuff composition is less than 10% by mass out of 100% by mass of the dyestuff composition.

[0025] In addition, the content of component (D) in the whole dyestuff composition is preferably 8% by mass or less, more preferably 5% by mass or less, out of 100% by mass of the dyestuff composition.

[0026] (Other dyes) The dye material composition of the present invention may contain, as other dyes, dyes other than the above-described components (A) to (B). Examples of other dyes include basic dyes such as Basic Blue 9, Basic Blue 75, Basic Blue 77, Basic Orange 31, Basic Violet 16; HC dyes such as HC Blue 17, HC Blue 11, HC Blue 13, HC Blue 14, HC Yellow 2, HC Yellow 7, HC Yellow 9, HC Yellow 10, HC Yellow 11, HC Yellow 12, HC Yellow 13, HC Yellow 14, HC Yellow 15, HC Orange 1, HC Orange 2, HC Violet 1, HC Violet 2, HC Red 1, HC Red 3, HC Red 7, HC Red 10, HC Red 11, HC Red 13; acid dyes such as Red No. 2, Red No. 3, Red No. 102, (1) of Red No. 104, (1) of Red No. 105, Red No. 106, Red No. 201, Red No. 227, (1) of Red No. 230, (2) of Red No. 230, Red No. 231, Red No. 232, Red No. 401, Red No. 502, Red No. 503, Red No. 504, Red No. 506, Yellow No. 4, Yellow No. 5, (1) of Yellow No. 202, (2) of Yellow No. 202, Yellow No. 203, Yellow No. 402, (1) of Yellow No. 403, Yellow No. 406, Yellow No. 407, Orange No. 205, Orange No. 207, Orange No. 402, Green No. 3, Green No. 204, Green No. 205, Green No. 401, Green No. 402, Violet No. 401, Blue No. 1, Blue No. 2, Blue No. 202, Blue No. 203, Blue No. 205, Brown No. 201, Black No. 401, Acid Blue 1, Acid Blue 3, Acid Blue 62, Acid Black 52, Acid Brown 13, Acid Green 50, Acid Orange 6, Acid Red 14, Acid Red 35, Acid Red 73, Acid Red 184, Brilliant Black 1, and the like. These can be used alone or in combination of two or more.

[0027] Further, from the viewpoint of effectively suppressing the dyeing on the fabric, the content of other dyes in the dye material composition of the present invention is preferably 0% by mass or more and 1% by mass or less based on the total amount of dyes in the dye material composition (i.e., 100% by mass of dyes).

[0028] (pH adjuster) In addition, the hair dye composition of the present invention contains a pH adjuster. This pH adjuster is not particularly limited, and any one that is usually used in a hair dye composition may be used. For example, phosphoric acid, lactic acid, citric acid, pyrrolidonecarboxylic acid, glycolic acid, levulinic acid, tartaric acid, malic acid, succinic acid, maleic acid, fumaric acid, malonic acid, and their salts (e.g., sodium phosphate and disodium phosphate), arginine, etc. may be mentioned. These can be used alone or in combination of two or more.

[0029] The content of the pH adjuster in the hair dye composition of the present invention with respect to the whole is not particularly limited, but among 100% by mass of the hair dye composition, 0.01% by mass or more and 1% by mass or less is preferable.

[0030] And the pH of the hair dye composition of the present invention is set to an optimal range (3 to 7) in order to obtain a visually recognizable vivid color development by using these pH adjusters.

[0031] In addition, when the pH is less than 3, the hair becomes positively charged during application, making it difficult for the dye to adsorb, and thus it becomes difficult to obtain a visually recognizable vivid color development. Similarly, when the pH is greater than 7, the dye is decomposed, and thus it becomes difficult to obtain a visually recognizable vivid color development.

[0032] (Solvent) In addition, the solvent (dispersion medium) used in the hair dye composition of the present invention is not particularly limited, and water (purified water) is used. If necessary, organic solvents such as methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, ethylene glycol, diethylene glycol, triethylene glycol, benzyl alcohol, 2-phenylethyl alcohol, and phenoxyethanol may be contained in water at a concentration harmless to human body contact.

[0033] (Other components) In the hair dye composition of the present invention, within a range not impairing the effects of the present invention, as other components, for example, oily components (such as almond oil, shea butter, hydrogenated castor oil, hydrogenated polyisobutene, microcrystalline wax, macadamia oil, beeswax, jojoba oil, polyglycerin fatty acid ester, lanolin, liquid paraffin, etc.), higher alcohols (such as isostearyl alcohol, oleyl alcohol, stearyl alcohol, cetanol, cetearyl alcohol, behenyl alcohol, myristyl alcohol, etc.), silicones (such as amodimethicone, cyclopentasiloxane, dimethiconol, dimethicone, etc.), cationic surfactants (such as distearyldimonium chloride, steartrimonium chloride, cetrimonium chloride, behentrimonium chloride, behentrimonium methosulfate, etc.), nonionic surfactants (such as polyoxyethylene alkyl ethers such as polyoxyethylene cetyl ether and polyoxyethylene lauryl ether, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene hydrogenated castor oil, alkyl glucoside, new oil type glyceryl monostearate, etc.), preservatives (such as sodium benzoate, phenoxyethanol, propylparaben, methylparaben, etc.), thickeners (hydroxyethyl cellulose, gum arabic, guar gum, xanthan gum, rice starch, hydroxypropyl starch phosphate, carbomer, sodium polyacrylate, polyvinylpyrrolidone, (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer, and (acrylic acid / acrylamide methylpropanesulfonic acid) copolymer, etc.), and fragrances, etc. can be blended.

[0034] (Form of the hair dye composition) The hair dye composition of the present invention can be made into forms such as liquid, milk-like, cream-like (gel-like), foam-like (shape at the time of use), mist-like (shape at the time of use), etc. by known methods, and can also be made into an aerosol form.

[0043] <Preparation of Hair for Samples> A hair bundle (5 g) consisting of straight hair with a length of 30 cm was used. As a chemical treatment, a commercially available bleaching agent was used for two decolorization treatments, and then a permanent wave treatment was performed with a commercially available perm solution. Thereafter, the treated hair was immersed overnight in an aqueous solution of sodium lauryl polyoxyethylene sulfate (5% by mass) maintained at 50°C and thoroughly washed with water to obtain hair for samples ("hair with a high brightness of yellowish-brown color").

[0044] <Hair dyeing treatment> Next, the following treatments (A) to (C) were performed on the prepared hair for samples. (A) First, 10 g of each hair dye composition of the examples, comparative examples, and reference examples was prepared for 5 g of the hair for samples (after being wetted with water and then towel-dried). (B) Next, each prepared hair dye composition was uniformly applied to the entire hair, and after the hair dyeing treatment, it was left at room temperature for 10 minutes. (C) Then, the hair after being left at room temperature was rinsed with water and shampooed, and thereafter, the hair was dried using a dryer.

[0045] <Skin dyeing treatment> Next, the following skin dyeing treatments (D) to (H) were performed on the forearms of professional panelists. (D) First, 0.5 g of each hair dye composition of the examples, comparative examples, and reference examples was prepared. (E) Next, each prepared hair dye composition was applied to the forearms of professional panelists and left at room temperature for 10 minutes. (F) Then, after the 10-minute skin dyeing treatment, the forearms were rinsed with water and shampooed, and thereafter, the forearms were dried using a towel.

[0046] <Evaluation criteria> Next, regarding the effect of each hair dye composition used in the treatment (B) on the finish feeling of the hair dyeing treatment, a sensory evaluation was performed on the hair subjected to the hair dyeing treatments (A) to (C) above. Specifically, (1) the color development of the dyeing was evaluated by 10 professional panelists.

[0047] In addition, for the upper arm part subjected to the skin dyeing treatments (D) to (F) above, a sensory evaluation was conducted on the effect of each dye material composition used in the treatment (E) on the skin dyeing treatment. Specifically, (2) the inhibitory effect on dyeing on the base fabric was evaluated by 10 professional panelists.

[0048] (1) Color development property of dyeing The color development when using each dye material composition of the examples and comparative examples was compared with the color development when using the dye material compositions of the reference examples corresponding to each dye material composition of these examples and comparative examples (excluding the penetrants of components (C) to (D) from each dye material composition of the examples and comparative examples, and having the same other formulations), and the color development property of each dye material composition of the examples and comparative examples was evaluated.

[0049] For example, the color development of the dye material composition of Example 1 was compared with the color development of the dye material composition of Reference Example 1 obtained by removing the penetrants of components (C) to (D) from the dye material composition of Example 1, and the color development property of the dye material composition of Example 1 was evaluated.

[0050] Note that each dye material composition of the examples and comparative examples compared with each dye material composition of Reference Examples 1 to 13 is as follows.

[0051] Compared with Reference Example 1: Examples 1 to 14, Examples 27 to 48, Comparative Examples 1 to 10 Compared with Reference Example 2: Example 15 Compared with Reference Example 3: Example 16 Compared with Reference Example 4: Example 17 Compared with Reference Example 5: Example 18 Compared with Reference Example 6: Example 19 Compared with Reference Example 7: Example 20 Compared with Reference Example 8: Example 21 Compared with Reference Example 9: Example 22 Compared with Reference Example 10: Example 23 Compared with Reference Example 11: Example 24 Compared with Reference Example 12: Example 25 Compared with Reference Example 13: Example 26

[0052] Then, the color development properties of each hair dye composition of the examples and comparative examples were evaluated according to the following evaluation criteria.

[0053] Compared with the case of using the hair dye composition of the reference example, the color development is very vivid: ◎ Compared with the case of using the hair dye composition of the reference example, the color development is sufficiently vivid: 〇 The color development is the same as that in the case of using the hair dye composition of the reference example, and the color development is insufficient: ×

[0054] Here, "the color development is vivid" means that the color development in the hair can be recognized as vivid visually. Also, "the color development is insufficient" means that the color development in the hair is poor, the color of the hair before dyeing (yellow with a brownish tint) is prominent, and it is difficult to recognize the color development.

[0055] (2) Suppression of dyeing on the skin The dyeing on the upper arm when using each hair dye composition of the examples and comparative examples was compared with the dyeing on the upper arm when using the hair dye composition of the reference example corresponding to each hair dye composition of these examples and comparative examples (excluding the penetrants of components (C) to (D) from each hair dye composition of the examples and comparative examples, and having the same other formulations), and the suppression of dyeing on the skin of each hair dye composition of the examples and comparative examples was evaluated.

[0056] For example, the dyeing on the upper arm when using the hair dye composition of Example 1 was compared with the dyeing on the upper arm when using the hair dye composition of Reference Example 1 obtained by removing the penetrants of components (C) to (D) from the hair dye composition of Example 1, and the suppression of dyeing on the skin of the hair dye composition of Example 1 was evaluated.

[0057] In addition, each hair dye composition of the examples and comparative examples compared with the hair dye compositions of Reference Examples 1 to 13 is the same as in the case of the above-mentioned "evaluation of color development of dyeing".

[0058] Then, the inhibitory effect on dyeing of the background fabric in each of the dyed wool material compositions of the examples and comparative examples was evaluated according to the following evaluation criteria.

[0059] Similar to the case of using the dyed wool material composition of the reference example, there is no dyeing on the background fabric and no color residue: ◎ Compared with the case of using the dyed wool material composition of the reference example, there is slightly visible dyeing on the background fabric, but the color residue is not prominent: 〇 Compared with the case of using the dyed wool material composition of the reference example, there is visible dyeing on the background fabric and the color residue is prominent: ×

[0060] (3) The temporal stability of the aluminum container filled with the dyed wool material composition Next, after filling each of the dyed wool material compositions of the examples and comparative examples into an aluminum container (diameter: 30 mm, weight: 120 g), the aluminum container was stored for 3 months at room temperature and in a constant temperature bath at 40 °C and 50 °C. Then, the state of the aluminum container after 3 months was observed and evaluated according to the following evaluation criteria.

[0061] In any temperature condition, there is no corrosion or deformation of the aluminum container: ◎ In any of the temperature conditions of room temperature, 40 °C, and 50 °C, there is slightly visible expansion of the aluminum container, but there is no rupture or perforation of the aluminum container and no corrosion: 〇 In any of the temperature conditions of room temperature, 40 °C, and 50 °C, there is visible expansion of the aluminum container, and there is rupture or perforation of the aluminum container: ×

[0062] In each of the above evaluations (1) to (3), "◎" was evaluated as particularly excellent, and "〇" was evaluated as excellent. Also, "×" was evaluated as insufficient. The above results are shown in Tables 1 to 5.

[0063] As shown in Tables 1 to 4, as component (A), it contains at least one basic dye selected from the group consisting of Basic Red 51, Basic Red 76, Basic Orange 31, Basic Yellow 57, Basic Yellow 87, Basic Blue 99, Basic Blue 124, Basic Violet 2, Basic Brown 16, Basic Brown 17, and Red 213; as component (B), it contains at least one HC dye selected from the group consisting of HC Yellow 4, HC Blue 2, HC Blue 12, and HC Blue 16; as component (C), it contains at least one of a sugar alcohol having 6 to 12 carbon atoms and a polyhydric alcohol having 3 to 5 carbon atoms; as component (D), it contains at least one of a monohydric alcohol having 2 to 8 carbon atoms and an aromatic alcohol having 6 to 8 carbon atoms, the content of component (D) is less than 10% by mass, and the pH is 3 to 7. In Examples 1 to 48 using the hair dye composition, it can be seen that a visually recognizable vivid color development can be obtained, the dyeing on the fabric can be suppressed, and the corrosion and deformation of the aluminum container filled with the hair dye composition can be suppressed.
