Description

[Technical field]

[0001] The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dye composition that can control the yellowing of hair and thereby realize a desired color. [Background technology]

[0002] Hair dyes and hair colorants can be classified according to the dye used or whether they have a bleaching effect on melanin.

[0003] Representative examples of hair dyes include semi-permanent hair dyes containing basic dyes such as acid dyes, basic blue 99, basic brown 16, basic blue 75, basic blue 124, and basic red 76, HC dyes such as HC blue 2, HC yellow 2, and HC yellow 4, and direct dyes such as nitro dyes.

[0004] Representative examples of dyeing methods are classified into permanent hair dyes, semi-permanent hair dyes, and temporary hair dyes, with color shampoos and color treatments being classified as semi-permanent hair dyes.

[0005] Prior art patents that have been submitted include Patent Document 1, which describes a hair cosmetic that contains a legally required dye to make yellowing of hair after bleaching and yellowing of gray hair less noticeable, and Patent Document 2, which describes a hair whitening agent. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent application 2018-098100 [Patent Document 2] Patent application 2019-239502 Summary of the Invention [Problem to be solved by the invention]

[0007] Unlike hair dyes, hair dyes do not have the power to lighten black hair, so when dyeing black hair, existing hair, or gray hair, the yellowing of the hair after bleaching or the yellowing of gray hair may affect the result, and you may not be able to achieve the original color you were aiming for. If we can control and suppress the yellowing of hair after bleaching, gray hair, and residual yellowing from previous hair coloring, we believe that it will be easier to imagine the final color and the range of colors that can be expressed will increase dramatically.

[0008] Conventional prior art technologies aim to suppress yellowing after bleaching or yellowing of gray hair, but legal dyes have a limited ability to suppress yellowing because there is a lack of diversity in the agents, resulting in weak dyeing power, and they are easily affected by pH.

[0009] The present invention has been made in consideration of the problems associated with the above-mentioned conventional techniques, and dyes suitable for controlling and inhibiting the yellowing of hair after bleaching and the yellowing of gray hair have been investigated. The purpose of this invention is to dramatically improve the expression of the color of the finished hair after dyeing by controlling the yellowing of the hair and making the hair closer to white.

[0010] The present invention relates to a dye that controls and suppresses yellowing, and by applying the technology of conventional hair dye compositions to the dye, it has been possible to control and suppress yellowing, thereby dramatically improving hair dyeability. In other words, it was possible to achieve a better effect than the legal dyes reported in the prior art. [Means for solving the problem]

[0030] Furthermore, the hair dye composition of the present invention can control and suppress the yellowing of hair after bleaching and the yellowing of gray hair during dyeing, thereby allowing the expression of the original image of the hair dye color. [Brief description of the drawings]

[0031] [Figure 1] Table 1 shows the components and evaluation results of samples for examples and comparative examples of the present invention. [Diagram 2] Table 2 shows the components and evaluation results of the specimens for examples and comparative examples of the present invention. [Diagram 3] Table 3 shows the components and evaluation results of the specimens for examples and comparative examples of the present invention. [Figure 4] Table 4 shows the components and evaluation results of the specimens for examples and comparative examples of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] <Technical background> First, the technical background will be explained. Conventional color shampoos and color treatments are based on the three primary colors, and it is common to design a variety of colors by combining Basic Blue 99, HC Blue 16, Basic Blue 124, HC Yellow 4, HC Yellow 87, Basic Red 51, Basic Red 76, etc. To combat the yellowing of grey or bleached hair, hair salons sell products specifically designed to remove yellowing, such as purple shampoo and white collars that contain dyes such as Purple No. 401 and HC Blue 2 to make hair appear whiter.

[0033] Conventional hair dyes are not designed to remove yellowing and color hair at the same time. In addition, there are hair dyes that use the complementary color of HC Blue 2 in conventional formulas, but HC Blue 2 has problems with poor dye stability and is prone to deterioration, and there are concerns that it is prone to crystallization when used in excess. Also, due to the characteristics of the dye, if you rely too much on HC Blue 2, the color will become cloudy and it will be difficult to achieve a beautiful color. There is also a concern that it is difficult to accommodate a variety of formulations due to compatibility issues with legal pigments.

[0034] However, with the hair dye composition of the present invention, by blending HC Blue 12, it is possible to control and suppress the yellowing of hair after bleaching and the yellowing of gray hair while coloring the hair, so the finished color is not influenced by yellow, and it is possible to dye in a variety of colors, and it is also possible to improve the color retention and achieve the color you imagine. In addition, we have developed a method to make gray hair look beautiful by dyeing while approximating the contrast between gray hair and black hair.

[0035] The hair dye composition according to the present invention will now be described. The hair dye composition of the present invention is a hair dye composition that contains HC Blue 12 and one or more of HC dyes, basic dyes, nitro dyes (direct dyes), and acid dyes. However, the blending amount of the dye (HC Blue 12) (when using the hair dye composition) is more than 0.0 mass % and 1.0 mass % or less, more preferably 0.01 mass % or more and 1.0 mass % or less. By adjusting the content to this mass %, yellowing can be controlled and inhibited. If this amount is not included, yellowing cannot be controlled, so it is necessary to include more than 0.0 mass%. On the other hand, if there is too much, the blue component becomes too strong. From the above, the above ingredients are suitable.

[0036] In other words, HC Blue 12 is effective even in small amounts, but when used in combination with other dyes, it is more effective when used at 0.01% or more.

[0037] The amount of the additional dye is suitably greater than 0.005% by weight and not more than 0.7% by weight. The reason for this amount is that if there is no effect if there is no color at all, but if there is too much, the color added will have too much of an effect.

[0038] The hair dye composition of the present invention can be effective as a temporary hair dye, a color shampoo, or a color treatment.

[0039] The hair dye composition according to the present invention preferably has a pH of 5.00 to 8.00, but when one or more of HC Blue 16, Basic Yellow 87, Basic Orange 31, and Basic Red 51 are blended to prepare the hair dye composition, a pH of 8.00 or higher is acceptable. Furthermore, although not mentioned in the tables of Figures 1 to 4, it has been found that HC Yellow 4 has the same role as Basic Yellow 87 and produces similar results.

[0040] In addition, by adding a penetration enhancer and a hair protecting agent to the hair dye composition of the present invention, a more preferable additive effect, that is, the effect of being able to dye hair while caring for the hair, tends to be exhibited.

[0041] Examples of the penetration enhancer include 1,3-butylene glycol, sodium dilauroyl glutamate lysine, cyclohexane-1,4-dicarboxylate bisethoxydiglycol, urea, etc. These may be used alone or in combination of two or more kinds as necessary. However, other penetration enhancers may also be used.

[0042] Examples of hair protection agents include keratin such as N-[2-hydroxy-3-(trimethylammonio)propyl] chloride hydrolyzed keratin solution and N-[2-hydroxy-3-(lauryldimethylammonio)propyl] chloride hydrolyzed keratin solution, etc. However, other hair protection agents may also be used.

[0043] In addition, the hair dye composition of the present invention may contain, as necessary, one or more pH adjusters selected from the group consisting of ammonium bicarbonate, aqueous ammonia, monoethanolamine, and aluminum chloride, in order to improve dye adhesion and pH stability.

[0044] The hair dye composition according to the present invention preferably contains, as a pigment or dye, an acid dye, a basic dye, a HC dye, a direct dye, etc., which may be used alone or in combination of two or more kinds, if necessary. By containing these pigments or dyes, it is possible to dye hair in a variety of colors.

[0045] Acid dyes include those designated by the Ministry of Health and Welfare Ordinance No. 30, promulgated on August 31, 1966, "Ministry Ordinance Specifying the Tar Dyes That Can Be Used in Pharmaceuticals, etc." There are no particular limitations on the acid dyes as long as they are acid dyes that can be commonly used in hair dyes, and examples of such acid dyes include Red No. 2, Red No. 3, Red No. 102, Red No. 104, Red No. 105, Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Blue No. 2, Red No. 201, Red No. 227, Red No. 220, Red No. 230, Red No. 231, Red No. 232, Orange No. 205, Orange No. 207, and Yellow No. 202. , Yellow No. 203, Green No. 201, Green No. 204, Green No. 206, Blue No. 202, Blue No. 203, Blue No. 205, Red No. 401, Red No. 502, Red No. 503, Red No. 504, Red No. 506, Orange No. 402, Yellow No. 402, Yellow No. 403, Yellow No. 406, Yellow No. 407, Brown No. 201, Green No. 401, Green No. 402, Purple No. 401, and Black No. 401.

[0048] Examples of direct dyes include nitro dyes such as 2-amino-6-chloro-4-nitrophenol, 2-amino-3-nitrophenol, 4-amino-3-nitrophenol, hydroxyanthraquinone aminopropylmethylmorphonium methosulfate, 3-methylamino-4-nitrophenoxyethanol, 2-nitro-5-glycerylmethylaniline, and N,N-Bis(2-hydroxyethyl)-2-nitro-p-phenylenediamine.

[0049] The content of the above-mentioned pigments and dyes is preferably 2% by weight or less, and more preferably 0.01 to 1% by weight. If it exceeds 2% by weight, the pigments and dyes tend to stain the skin more easily.

[0050] Furthermore, the hair dye contained in the hair dye composition according to the present invention can contain various ingredients that are commonly used in cosmetics and hair dyes, provided that the effects of the present invention are not impaired.

[0051] Examples of surfactants include cationic surfactants such as stearyltrimethylammonium chloride, tri(polyoxyethylene)stearylammonium chloride (5E.O.), and cetyltrimethylammonium chloride; anionic surfactants such as sodium tetradecene sulfonate solution, sodium lauroylmethyl-β-alanine solution, and sodium polyoxyethylene alkyl(12,13) ​​ether sulfate (3E.O.); nonionic surfactants such as alkyl polyglucosides, polyoxyethylene castor oil, and polyoxyethylene hydrogenated castor oil; and amphoteric surfactants such as 2-alkyl-N-carboxymethyl-N-hydroxyethyl imidazolinium betaine, coconut oil fatty acid amidopropyl betaine solution, and lauric acid amidopropyl betaine solution.

[0052] The hair dye composition according to the present invention may be in the form of a liquid, gel, cream or foam, and the form of the storage container is not particularly limited.

[0053] In addition, the hair dye composition according to the present invention can be used alone or by mixing a plurality of components at the time of use to obtain a desired color, thereby enabling a wide variety of shades to be expressed.

[0054] The hair dye composition according to the present invention can be used immediately after a hair dye, making it possible to correct color after hair coloring.

[0055] The hair dye composition according to the present invention will be specifically described below with reference to examples and comparative examples. The values ​​in the tables indicate mass %.

[0056] <Example> A-1 shown in Table 1 of FIG. 1 is an example specimen related to claim 1. It should be noted that Tables 1 to 3 in Figures 1 to 3 assume ingredients for color treatments.

[0057] Moreover, B-1 and B-2 shown in Table 1 are comparative samples of A-1.

[0058] The blending amount of dyes (HC dyes, basic dyes, direct dyes, acid dyes) in each example sample was more than 0.0% by mass and 1.0% by mass or less.

[0059] [Hair dyeing method] Approximately 2g of each sample was applied to 1g of goat hair, white hair, or bleached hair (manufactured by Beaulax) bundles of approximately 10cm in length. After leaving it for 10 minutes, it was washed with running water at approximately 40°C for 30 seconds and air-dried.

[0060] [Evaluation method] Measurements were taken using a color difference meter (MINOLTA SPECTROPHOTOMETER CM-26dG, manufactured by Minolta Co., Ltd.), and the wavelength after dyeing was calculated using goat hair, white hair, and bleached hair before dyeing as blanks.

[0061] Electromagnetic waves in the wavelength range that the human eye perceives as light. The lower limit of the wavelength range is 360-400 nm, and the upper limit is 760-830 nm. The wavelength of visible light is often expressed in units of nm (nanometers). 1 nm = 1 x 10 -9 m. Different wavelengths give different color sensations, and are perceived as purple (380-430 nm), blue (430-490 nm), green (490-550 nm), yellow (550-590 nm), orange (590-640 nm), and red (640-770 nm). That is, the change in 550 to 590 nm (yellow wavelength) was measured from untreated goat hair, white hair, and bleached hair, and the smaller the value, the more the yellowing of the hair was inhibited.

[0062] Then, taking into consideration that the higher the rate of change in the wavelength of yellow, the greater the inhibition of yellowing, the hair dyeing power was evaluated according to the following criteria. ◎: Yellowing of goat hair, white hair or bleached hair is significantly suppressed. ○: It is clear that the yellowing of goat hair, white hair, or bleached hair is suppressed. △: It is clear that the yellowing of goat hair, white hair or bleached hair is not significantly suppressed. ×: It is clear that the yellowing of goat hair, white hair or bleached hair is not suppressed.

[0063] As a result, the results were as shown in the bottom three rows of Table 1 in Figure 1. As can be seen from Table 1 in FIG. 1, HC Blue 12 shows superior results compared to when it contains HC Blue 2 and Purple No. 401. It can be seen that such results are obtained when the mass percentage of HC Blue 12 is 0.05 mass%.

[0064] Here, the mass percentage of HC Blue 12 does not have to be 0.05 mass%, as mentioned above, but rather needs to be greater than 0.00 mass%, and similar results were obtained if the mass percentage was 1.0 mass% or less (measured value omitted). The results showed that the content is preferably 0.01% by mass or more and 1.0% by mass or less.

[0065] A-2 shown in Table 2 of Figure 2 is an experimental sample in which HC Blue 12 is combined with other dyes. Also, B-3, B-4, and B-5 shown in Table 2 of FIG. 2 are comparative samples for A-2. [Hair dyeing method] Approximately 2g of each sample was applied to 1g of goat hair, white hair, or bleached hair (manufactured by Beaulax) bundles of approximately 10cm in length. After leaving it for 10 minutes, it was washed with running water at approximately 40°C for 30 seconds and air-dried. [Evaluation method] Each dyed hair bundle was visually inspected and evaluated for the degree of dyeing. ◎: Goat hair, white hair or bleached hair, white hair mixed 70% is clearly dyed ○: Goat hair, white hair or bleached hair, white hair mixed with 70% dyed hair △: Goat hair, white hair or bleached hair, white hair mixed 70% is not dyed very much ×: Goat hair, white hair or bleached hair, white hair mixed 70% is not dyed at all

[0066] As a result, the results were as shown in the bottom three rows of Table 2 in Figure 2. As can be seen from Table 2 in FIG. 2, HC Blue 12 shows superior results to the case where it contains HC Blue 2 and Purple No. 401.

[0067] Furthermore, when comparing these results with those in Table 1 of FIG. 1, it can be seen that there is no problem even if the ink contains Basic Brown 16, HC Blue 16, and Basic Blue 99.

[0068] Here, Basic Brown 16 was 0.15% by mass, HC Blue 16 was 0.01% by mass, and Basic Blue 99 was 0.30% by mass. As described above, it was found that similar results were obtained for this value as long as it was greater than 0.005 mass % and equal to or less than 0.7 mass %.

[0069] A-3 shown in Table 3 of Figure 3 is an example sample in which HC Blue 12 is combined with other dyes. Also, B-6 shown in Table 3 of FIG. 3 is a comparative sample for A-3.

[0070] The staining method and evaluation criteria were the same as those in Table 2 of Figure 2. From this, it can be seen that there is no problem even if Basic Red 51, Basic 87, and Basic Blue 124 are contained. On the other hand, if HC Blue 12 is not added, problems with dyeing will occur if only Basic Red 51, Basic 87, and Basic Blue 124 are used. Here, Basic Red 51 was 0.01% by mass, Basic 87 was 0.001% by mass, and Basic Blue 124 was 0.01% by mass. As described above, it was found that similar results were obtained for this value as long as it was greater than 0.005 mass % and equal to or less than 0.7 mass %.

[0071] Table 4 in FIG. 4 shows examples for A-4, A-5 and A-6. Here, B-7, B-8 and B-9 are comparative samples for A-4, A-5 and A-6. It should be noted that while Tables 1 to 3 in Figs. 1 to 3 show the components of a color treatment, Table 4 in Fig. 4 shows the measurement results when the product was used as a color shampoo. Because this is a color shampoo, the ingredients are different from those in Tables 1 to 3.

[0072] [Hair dyeing method] Approximately 2g of each sample was applied to 1g of goat hair, white hair, or bleached hair (manufactured by Beaulax) bundles of approximately 10cm in length. After leaving it for 10 minutes, it was washed with running water at approximately 40°C for 30 seconds and air-dried.

[0073] [Evaluation method] Measurements were taken using a color difference meter (MINOLTA SPECTROPHOTOMETER CM-26dG, manufactured by Minolta Co., Ltd.) in the CIE color system (L*a*b*), and the color difference ΔE*ab was calculated using the following formula, with the goat hair before dyeing as the blank.

[0074] Color difference ΔE*=[(ΔL*)^2+(Δa*)^2+(Δb*)^2]^(1 / 2) Saturation C*=[(Δa*)^2+(Δb*)^2]^(1 / 2) ΔL*: Difference in L* value before and after hair dyeing Δa*: Difference in a* value before and after hair dyeing Δb*: Difference in b* value before and after hair dyeing

[0075] In other words, when the color difference (ΔE*ab) for untreated goat hair is taken as 0, the larger the value, the higher the dyeing ability.

[0076] Then, based on the fact that the larger the color difference ΔE*ab, the higher the dyeing ability, this value was used as a reference and the dyeing power was evaluated based on which of the following conditions could be predicted from this value. ◎: The goat hair is very well colored. ○: The goat hair is visually stained. △: It is visible that the goat hair is not very colored. ×: It is visible to the naked eye that the goat hair is almost not colored.

[0077] [Evaluation Results] Therefore, A-4, A-5 and A-6 had better dyeing ability than the conventional hair dye compositions.

[0078] Here, in Table 4, when Basic Red 51 is included, it is 0.01 mass percent, when Basic Brown 16 is included, it is 0.1 to 0.3 mass percent, when Basic Blue 99 is included, it is 0.2 to 0.3 mass percent, and when Basic Yellow 87 is included, it is 0.03 mass percent. In this case, as described above, it was found that, when these elements are contained, the same results were obtained so long as the content was more than 0.005 mass % and 0.7 mass % or less. [Industrial Applicability]

[0079] The present invention is suitable as a hair dye composition.
