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 in 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, when performing a stripping treatment with a stripping agent (bleaching agent), it is difficult to remove the basic dye from the hair. Therefore, in order to suppress the residue of the basic dye in the hair, it is necessary to lower the concentration of the basic dye in the hair dye composition. As a result, there has been a problem that the dyeability with respect to the hair is reduced, it becomes difficult to obtain a visually recognizable vivid color development, and it becomes difficult to suppress the color tone change due to fading.

[0006] In addition, the hair dye composition may be used simultaneously (for example, mixed) with a two-component oxidative hair dye (an oxidative hair dye composed of a first component containing an oxidative dye and an alkaline agent such as ammonia, and a second component containing an oxidizing agent). In this case, there has been a problem that since decomposition or denaturation of the basic dye in the hair dye composition occurs, it becomes difficult to obtain the same color development as when the hair dye composition is used alone.

[0007] Therefore, the present invention has been made in view of the above problems, and can obtain a visually recognizable vivid color development, can suppress the color tone change due to fading, and is easy to perform a stripping treatment. Even when used simultaneously with a two-component oxidative hair dye, an object of the present invention is to provide a hair dye composition capable of obtaining the same color development as when used alone.

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 of component (A1) which is at least one selected from the group consisting of Basic Blue 124 and Basic Violet 2, and component (A2) which is HC Blue 16, and as component (B), contains at least one selected from the group consisting of Basic Red 51 and Basic Yellow 87, and the total content of component (A) and component (B) is 0.5% by mass or less, and the content of component (A1) is 0% by mass or more and 0.02% by mass or less.

Effects of the Invention

[0009] According to the present invention, a visible and vivid color development can be obtained, a change in color tone due to fading can be suppressed, the stripping treatment is easy, and even when used simultaneously with a two-component type oxidative hair dye, the same color development as when used alone can be obtained.

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 changed 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, HC dye) The hair dye composition of the present invention contains, as a purple-based dye (hereinafter sometimes referred to as component (A)), at least one selected from the group consisting of basic blue 124 and basic violet 2 (hereinafter sometimes referred to as component (A1)), and at least one of HC blue 16 (hereinafter sometimes referred to as component (A2)).

[0013] And, in the hair dye composition of the present invention, the content of component (A1) with respect to the whole hair dye composition (that is, 100% by mass of the hair dye composition) is characterized in that it is 0% by mass or more and 0.02% by mass or less.

[0014] This is because when the content of component (A1) is more than 0.02% by mass, the concentration of component (A1) becomes too high, making it difficult to obtain a vivid color development. Further, when the hair dye composition of the present invention is used simultaneously with a two-component type oxidative hair dye, the decomposition and denaturation of the basic dye in the hair dye composition are promoted, making it difficult to obtain the same color development as when the hair dye composition of the present invention is used alone (that is, to obtain a color tone equivalent to the color tone when the hair dye composition is used alone).

[0015] That is, when the content of component (A1) with respect to the whole hair dye composition is 0% by mass or more and 0.02% by mass or less, even when the brightness of the hair to be dyed is high, it becomes possible to obtain a visually recognizable vivid color development (purple color), and even when the hair dye composition of the present invention is used simultaneously with a two-component oxidative hair dye, it becomes possible to obtain the same color development as when the hair dye composition of the present invention is used alone.

[0016] In addition, the content of component (A) with respect to the whole hair dye composition of the present invention is preferably 0.01% by mass or more and 0.215% by mass or less out of 100% by mass of the hair dye composition.

[0017] In addition, from the viewpoint of suppressing the decomposition of basic dyes when used simultaneously with an oxidative hair dye, the hair dye composition of the present invention contains, as a basic dye, at least one selected from the group consisting of basic red 51 and basic yellow 87 (hereinafter sometimes referred to as component (B)).

[0018] And, the hair dye composition of the present invention is characterized in that the total of the content of component (A) and the content of component (B) with respect to the whole hair dye composition is 0.5% by mass or less.

[0019] This is because when the total of the content of component (A) and the content of component (B) is more than 0.5% by mass, the content of component (B) which is likely to cause a color tone change due to fading increases, making it difficult to suppress the color tone change due to fading, and in some cases, the decolorization treatment with a decolorizing agent (bleaching agent) becomes difficult after fading.

[0020] That is, when the total of the content of component (A) and the content of component (B) with respect to the whole hair dye composition is 0.5% by mass or less, even when faded, the color tone does not change from the color (purple) before fading, and it becomes possible to suppress the color tone change due to fading (for example, the color tone change to blue after fading caused by component (B)), and after fading, it becomes possible to easily perform the decolorization treatment with a decolorizing agent (bleaching agent).

[0021] Also, in the hair dye composition of the present invention, when the content of component (A1) with respect to the whole hair dye composition is X [% by mass], the content of component (A2) with respect to the whole hair dye composition is Y [% by mass], and the content of component (B) with respect to the whole hair dye composition is Z [% by mass], it is preferable that the relationship 1 ≦ Y / (X + Z) ≦ 10 holds (that is, (total content of component (A1) and component (B)): content of component (A2) = 1:1 to 1:10).

[0022] This is because when Y / (X + Z) is less than 1 (that is, when Y / (X + Z) < 1), the content of the dye that is likely to cause a color tone change due to fading increases, so it may be difficult to suppress the color tone change due to fading. When Y / (X + Z) is greater than 10 (that is, when 10 < Y / (X + Z)), when used simultaneously with the oxidative hair dye, the content of the dye that is likely to cause discoloration increases. Therefore, when the hair dye composition of the present invention is used simultaneously with a two-component oxidative hair dye, it may be difficult to obtain the same color development as when the hair dye composition of the present invention is used alone.

[0023] Also, in the hair dye composition of the present invention, when both component (A1) and component (A2) are contained, the ratio of the content of component (A1) [% by mass] with respect to the whole hair dye composition to the content of component (A2) [% by mass] with respect to the whole hair dye composition is preferably component (A1): component (A2) = 1:2 to 1:18 (that is, the content of component (A2) / the content of component (A1) is 2 or more and 18 or less).

[0024] When the content of component (A2) / the content of component (A1) is less than 2, when used simultaneously with an oxidative hair dye, the content of the dye that is likely to cause discoloration increases. Therefore, when the hair dye composition of the present invention is used simultaneously with a two-component oxidative hair dye, it may be difficult to obtain the same color development as when the hair dye composition of the present invention is used alone. This is because when the content of component (A2) / the content of component (A1) is greater than 18, the content of the dye that is likely to cause a change in color tone due to fading increases, and thus it may be difficult to suppress the change in color tone due to fading.

[0025] (Other dyes) The hair dye composition of the present invention may contain, as other dyes, dyes other than the above-mentioned components (A) to (B). Examples of other dyes include Basic Red 76, Basic Orange 31, Basic Yellow 57, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Blue 75, Red 213, HC Yellow 4, HC Blue 2, HC Blue 12, and the like. These can be used alone or in combination of two or more.

[0026] Also, from the viewpoints of suppressing the change in color tone after fading, the decrease in the decolorization treatment property, and the change in color tone when used in combination with an oxidative hair dye, the content of other dyes in the hair dye composition of the present invention is preferably 0% by mass or more and 1% by mass or less with respect to the total dyes in the hair dye composition (that is, 100% by mass of the dyes).

[0027] (pH adjuster) Moreover, the hair dye composition of the present invention contains a pH adjuster. This pH adjuster is not particularly limited and may be any one usually used in hair dye compositions. 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 (for example, sodium phosphate and disodium phosphate), arginine, and the like can be mentioned. These can be used alone or in combination of two or more.

[0028] In addition, the content of the pH adjuster relative to the whole of the wool dyeing material composition of the present invention is not particularly limited, but among 100% by mass of the wool dyeing material composition, 0.01% by mass or more and 1% by mass or less is preferable.

[0029] And, by using these pH adjusters, the pH of the wool dyeing material composition of the present invention can be set to 3 to 7.

[0030] (Solvent) Moreover, the solvent (dispersion medium) used in the wool dyeing material composition of the present invention is not particularly limited, and water (purified water) is used. However, 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 that is harmless even when in contact with the human body.

[0031] (Other components) In the hair dye composition of the present invention, within a range that does not impair 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 glucosides, 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.

Table 6

[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 lightness 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 and comparative examples was prepared for 5 g of the hair for samples (after wetting with water and then towel-drying). (B) Next, each prepared hair dye composition was uniformly applied to the entire hair, and after performing a purple hair dyeing treatment, it was left standing at room temperature for 10 minutes. (C) Then, the hair after standing at room temperature was rinsed with water and shampooed, and thereafter, the hair was dried using a dryer.

[0045] <Fading Treatment> Next, the following treatments (D) to (F) were performed on the hair subjected to the hair dyeing treatment. (D) First, a sufficient amount (200 ml for 5 g of the hair for samples) of an aqueous solution of sodium lauryl polyoxyethylene sulfate (5% by mass) was prepared as a fading solution and stored in a constant temperature bath at 40°C. (E) Next, the hair subjected to the hair dyeing treatment was immersed in the fading solution (40°C) prepared in (D) above for 60 minutes to perform a fading treatment. (F) Then, after the fading treatment in (E) above, the hair was rinsed with water, and thereafter, the hair was dried using a dryer.

[0046] <Decoloring treatment> Next, the following decoloring treatments (G) to (I) were performed on the hair that had been subjected to the fading treatment. (G) First, for 5 g of the hair for the sample that had been subjected to the fading treatment, 2.5 g of a commercially available decoloring agent (bleaching agent) and 7.5 g of the second agent (Reference Example 2) were prepared, and a mixture (10 g) of these decoloring agent and the second agent immediately before use was prepared. (H) Next, the decoloring agent (the one mixed with the second agent) prepared in (G) above was uniformly applied from the tip of the hair to half of the total hair length, and left for 10 minutes. (I) Then, after the decoloring treatment in (H) above, the hair was rinsed with water and shampooed, and then the hair was dried using a dryer.

[0047] <Evaluation criteria> Next, with respect to the hair on which the treatments (A) to (I) above were performed, a sensory evaluation was conducted on the effect of each hair dye composition used in the treatment (B) above on the finish feeling of the hair dyeing treatment. Specifically, evaluations were made by 10 professional panelists on four items: (1) color development of the dyeing, (2) color tone change after fading, (3) decoloring processability, and (4) color development when used in mixture with an oxidative hair dye. The evaluation criteria for each evaluation item are shown below.

[0048] (1) Color development of the dyeing Regarding the color development of the dyeing (purple) in the hair on which the above hair dyeing treatment was performed, evaluation was made according to the following evaluation criteria.

[0049] The purple color development is very vivid throughout the hair: ◎ The purple color development is sufficiently vivid throughout the hair: 〇 The purple color development is insufficient throughout the hair: △ The purple color development is poor throughout the hair: ×

[0050] Note that the phrase "vivid purple coloring" as used herein refers to a state where the purple coloring in the hair can be visually recognized as vivid. Also, the phrase "poor purple coloring" refers to a state where the hair has a brown or black tint, or where the purple coloring in the hair is poor, the color of the hair before dyeing (yellow with a brownish tint) is prominent, other colors (e.g., brown or orange) are mixed in, and it is difficult to recognize the purple color.

[0051] (2) Color change after fading Regarding the color change after fading in the hair that has undergone the above hair dyeing treatment and fading treatment, evaluation was conducted according to the following evaluation criteria.

[0052] The visibility of purple in the hair after fading (the hair that has undergone the above hair dyeing treatment and fading treatment) is the same as the visibility of purple in the hair before fading (the hair that has only undergone the above hair dyeing treatment and before the fading treatment), and there is no change: ◎ The visibility of purple in the hair after fading is equivalent to the visibility of purple in the hair before fading, and there is no significant change: 〇 The color tone of the hair after fading is slightly different from purple, and the visibility of purple in the hair after fading is different from the visibility of purple in the hair before fading: △ The color tone of the hair after fading is completely different from purple, and the visibility of purple in the hair after fading is significantly different from the visibility of purple in the hair before fading: ×

[0053] Note that the phrase "the color tone of the hair after fading is different from purple" as used herein refers to a state where the color tone of the hair after fading has changed to the color tone of another color (e.g., blue).

[0054] (3) Ease of stripping Regarding the ease of stripping (ease of decolorization) in the hair that has undergone the above hair dyeing treatment, fading treatment, and further the above stripping treatment, evaluation was conducted according to the following evaluation criteria.

[0055] In the hair after stripping, none of the color after fading remains, and the ease of stripping is extremely high: ◎ In the hair after stripping, almost no color remains after fading, and the stripping processability is high: 〇 In the hair after stripping, a little color remains after fading, and the stripping processability is poor: △ In the hair after stripping, a considerable amount of color remains after fading, and the stripping processability is extremely poor: ×

[0056] (4) Color development property when used in mixture with an oxidative hair dye The color development property of the dyeing was evaluated when hair dyeing treatment was carried out using a mixture of each hair dye composition of the examples and comparative examples and an oxidative hair dye composed of the above-mentioned first agent (Reference Example 1) and second agent (Reference Example 2).

[0057] More specifically, the following treatments (a) to (f) were carried out on the prepared hair. (a) First, for 5 g of hair for samples (after wetting with water and then towel-dried), 1 g of each hair dye composition of the examples and comparative examples, 5 g of the first agent (Reference Example 1), and 5 g of the second agent (Reference Example 2) were prepared. According to the mass ratio of the first agent: the second agent: each hair dye composition = 5:5:1 (5 g:5 g:1 g), the first agent, the second agent, and each hair dye composition were mixed to prepare a hair treatment agent for samples (a mixture of an oxidative hair dye and a hair dye composition in which the oxidative hair dye: hair dye composition = 10:1). (b) Next, the hair treatment agent for samples was uniformly applied to the entire hair, and after performing purple hair dyeing treatment, it was left at room temperature for 10 minutes. (c) Then, the hair after standing at room temperature was rinsed with water and shampooed, and then the hair was dried using a dryer. (d) Next, for 5 g of the hair for the sample (which was towel-dried after being wet with water), 1 g of each hair dye composition of the examples and comparative examples and 10 g of each diluent corresponding to each hair dye composition of the examples and comparative examples (the composition obtained by removing the dyes of components (A) to (B) and the dyes other than components (A) and (B) from each hair dye composition of the examples and comparative examples) were prepared. The hair dye compositions of the examples and comparative examples and the diluents were mixed at a ratio of each hair dye composition of the examples and comparative examples: each diluent corresponding to each hair dye composition of the examples and comparative examples = 1:10 (1 g:10 g) by mass ratio to prepare a hair treatment agent for comparison (a mixture of the hair dye composition and the diluent).

[0058] For example, in the hair dye composition of Example 1, a composition obtained by removing the dyes of components (A) to (B) from the hair dye composition of Example 1 was prepared as the diluent corresponding to Example 1, and the hair dye composition of Example 1 and the diluent were mixed at a ratio of 1:10 (1 g:10 g) to prepare a hair treatment agent for comparison (a mixture of the hair dye composition and the diluent). (e) Next, the hair treatment agent for comparison was uniformly applied to the entire hair, and after performing a purple hair dyeing treatment, it was left at room temperature for 10 minutes. (f) Then, the hair after being left at room temperature was rinsed with water and shampooed, and then the hair was dried using a dryer.

[0059] Then, the color development when using the hair treatment agent for the sample (a mixture of the oxidative hair dye and the hair dye composition) was compared with the color development when using the hair treatment agent for comparison (a mixture of the hair dye composition and the diluent), and the color development properties when each hair dye composition of the examples and comparative examples was mixed with the oxidative hair dye and used were evaluated according to the following evaluation criteria.

[0060] The color development when using the hair treatment agent for the sample is the same as the color development when using the hair treatment agent for comparison and does not change: ◎ The color development when using the hair treatment agent for the sample is equivalent to the color development when using the hair treatment agent for comparison and does not change significantly: 〇 When using the hair treatment agent for samples, the hair color is slightly lighter than when using the comparative hair treatment agent, or slight discoloration is observed: △ When using the hair treatment agent for samples, the hair color is significantly lighter than when using the comparative hair treatment agent, or significant discoloration is observed: ×

[0061] In each of the above evaluations (1) to (4), "◎" was evaluated as particularly excellent, and "○" was evaluated as excellent. Also, "△" and "×" were evaluated as insufficient. The above results are shown in Tables 1 to 4.

[0062] As shown in Tables 1 to 2, as component (A), at least one component (A1) selected from the group consisting of basic blue 124 and basic violet 2, and at least one of component (A2) consisting of HC blue 16 are contained. As component (B), at least one selected from the group consisting of basic red 51 and basic yellow 87 is contained. In Examples 1 to 20 using a hair dye composition in which the total content of component (A) and component (B) is 0.5% by mass or less and the content of component (A1) is 0% by mass or more and 0.02% by mass or less, it can be seen that a visually recognizable vivid purple hair color can be obtained, and the color tone change due to fading can be suppressed. Also, it can be seen that the decolorization treatment is easy. Further, it can be seen that even when used by mixing with a two-agent type oxidative hair dye, the same hair color as when used alone can be obtained.
