[0001] The present invention relates to a hair dyeing composition having viscosity characteristics suitable for use, being difficult to stain the skin and the bathtub, and stably coloring regardless of hair quality.

Background Art

[0002] Hair dyes are classified in the cosmetic category and can be classified as hair colors without a decolorizing effect.

[0003] Typical examples of hair dyes include semi-permanent hair dyes containing direct dyes such as acid dyes, basic dyes, HC dyes, and nitro dyes.

[0004] In cosmetics such as hair dyes or hair shampoos, when trying to dye gray hair or bleached hair to a dark color, there is a concern that the amount of dye formulation increases and the skin and bathtub become dirty. Therefore, gloves and combs are used to prevent staining, but the problem of the price of materials and the dirt on the bathtub is difficult to improve.

[0005] In addition, in a product called a color shampoo in which a dye is blended in a hair shampoo, there are problems such as a reduction in viscosity due to the dye and a decrease in dyeing properties due to the surfactant. In order to solve such problems, Patent Document 1 proposes a skin protectant such as a skin staining prevention method comprising a coating step of applying the skin protectant to the skin and a film forming step of volatilizing the volatile liquid medium to form the film on the skin. Patent Document 2 discloses a detergent composition containing a specific hydrophobic modified polyether urethane and an anionic surfactant and / or an amphoteric surfactant.

[0007] However, these inventions focus on pre-treatment agents to prevent hair color staining or studies on thickening shampoos, and do not include studies on preventing staining of the skin, bathtub, or sink at the same time as dyeing.

[0008] Hair dyes contain a high concentration of dye to achieve a deep color, raising concerns about staining the skin and soiling bathtubs and sinks. While brushes and gloves can mitigate skin staining, this introduces material costs. Furthermore, brushes and gloves cannot prevent staining of bathtubs and sinks. Furthermore, when dyes are added to a formulation, the viscosity of the formulation decreases, so there is a tendency to increase the amount of surfactant added to adjust the viscosity. In particular, shampoos contain a large amount of surfactant to maintain their cleansing power. In this case, if a large amount of surfactant is included, there is a problem that it will inhibit the dye from adhering properly.

[0009] This invention has been made in view of the problems of the prior art described above. Specifically, the objective is to provide a hair dye composition that significantly reduces staining on skin, bathtubs, and sinks by combining hydrophobic modified polyether urethane with dyes, and furthermore, stabilizes dye adhesion even when hair types differ due to the thickening effect of the hydrophobic modified polyether urethane. Furthermore, the objective is to provide a hair dye composition in which the hydrophobic modified polyether urethane encapsulates the dye, reducing direct contact with the skin and staining of bathtubs and other surfaces. [Means for solving the problem]

[0010] A hair dye composition according to a first aspect of the present invention contains one or more dyes selected from HC dyes, basic dyes, direct dyes, and acid dyes, and also contains hydrophobic modified polyether urethane.

[0011] Preferably, it contains 0.01 to 10% by mass of polyglycerin fatty acid ester.

[0012] Preferably, the mixture contains a cationized polymer and / or a water-soluble polymer having gelling properties.

[0013] <More suitable range> More preferably, the amount of the dye used is 1.0% by mass or less.

[0014] More preferably, the content of hydrophobic modified polyether urethane is 0.01 to 20% by mass relative to the total amount of the cosmetic composition.

[0015] More preferably, the polyglycerin fatty acid ester content is 10% by mass or less.

[0016] More preferably, while hydrophobic modified polyether urethane alone is acceptable, a water-soluble polymer is included as an auxiliary agent to adjust viscosity, which may be a natural polymer or its derivative, a cellulose derivative, or a synthetic polymer.

[0017] More preferably, citric acid, ammonium bicarbonate, and arginine may be included as agents to improve dyeing power and stabilize pH.

[0018] More preferably, the formulation contains the aforementioned dye and a hydrophobic modified polyether urethane, but the dosage form and storage container are not limited. [Effects of the Invention]

[0019] According to the hair dye composition of the present invention, by combining a hydrophobic modified polyether urethane and a dye and formulating the hydrophobic modified polyether urethane as an anti-fouling component and a viscosity adjuster, it can be made into a hair dye cosmetic that suppresses dirt on the skin, bathtub, and washbasin more than conventional hair colors. Since it can be used as a viscosity adjuster, the amount of surfactant added can also be suppressed.

[0020] Also, according to the hair dye composition of the present invention, compared with conventional color shampoos and color treatments containing direct dyes such as acid dyes, basic dyes, HC dyes, and nitro dyes, the film effect of the hydrophobic modified polyether urethane can reduce staining dirt on the skin, bathtub, and washbasin, and furthermore, it can exhibit stable dyeing properties that are not affected by hair quality.

[0021] Furthermore, according to the hair dye composition of the present invention, by using it as a viscosity adjuster, it is difficult to drip, and even one person can easily dye evenly without unevenness.

[0022] Furthermore, since the dye is incorporated during the association of the hydrophobicities of the hydrophobic modified polyether urethane and adsorbed onto the hair, it is considered that color transfer to towels and clothes can be suppressed.

Brief Description of the Drawings

[0023] [Figure 1] Table 1 showing the components and evaluation results of the specimens for the examples of the present invention. [Figure 2] Table 2 showing the components and evaluation results of the specimens for the comparative examples of the present invention. [Figure 3] Table 3 showing the components and evaluation results of the specimens for the comparative examples of the present invention. [Figure 4] Table 4 showing the components and evaluation results of the specimens for the comparative examples of the present invention.

[0024] Typical shampoos control viscosity using polyquaternium-10, anionic surfactants, amphoteric surfactants, and alkylolamide-type nonionic surfactants. However, when using alkylolamide-type nonionic surfactants, the viscosity is affected by the properties of the anionic and amphoteric surfactants, so a certain amount of surfactant must be added.

[0025] Furthermore, since polyquaternium-10 alone has concerns regarding thermal stability, the amount of surfactant added inevitably has to be increased in the design.

[0026] However, according to the hair dyeing composition of the present invention, by using hydrophobic modified polyether urethane, the viscosity is stabilized, and the dye adherence, which is affected by hair type, can be stabilized as the dye is incorporated into the hydrophobic modified polyether urethane. Furthermore, by incorporating hydrophobic modified polyether urethane, the agent does not stick to sinks or bathtubs and is not fixed to the contact surface, thus providing an effect that suppresses staining.

[0027] <Description of the components of the hair dye composition of the present invention 1> The cosmetic composition of the present invention may be appropriately formulated with other components, such as cationic surfactants, chelating agents, low molecular weight polyols, oily components, zinc compounds, thickeners (excluding hydrophobic modified polyether urethanes), powders, antibacterial preservatives, humectants, antioxidants, UV absorbers, metal ion sequestering agents, monosaccharides, oligosaccharides, polysaccharides, amino acids and their derivatives, organic amines, vitamins, cosmetic ingredients, fragrances, pH adjusters, and other blendable components, in order to improve and modify various properties (solubility, dispersibility, stability, feel, application, penetration, moisturizing properties, safety, aesthetic appeal, optical properties, fragrance, whitening properties, etc.) during storage, use, and after use, depending on the intended use, without impairing the objectives of the present invention.

[0028] <Description of the components of the hair dye composition of the present invention, Part 2> As a thickening agent other than hydrophobic modified polyether urethane, known thickening agents commonly used in cosmetics, excluding hydrophobic modified polyether urethane, can be used. For example, quaternary ammonium salt polymers such as polydimethylmethylenepiperidinium chloride, quaternary polyvinylpyrrolidone derivatives such as vinylpyrrolidone-N,N-dimethylaminoethyl methacrylate copolymer diethyl sulfate, cationic polymers such as polyquaternium-6,7,10, cationic starch, polyglycol polyamine condensates, adipic acid-dimethylaminohydroxypropylethylenetriamine copolymer, quaternary nitrogen-containing cellulose ether derivatives such as O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, and quaternary nitrogen-containing cellulose ether derivatives such as guar hydroxypropyltrimonium chloride. Examples include nitrogen-containing guar gum derivatives, cationized dextran, cellulose or its derivatives, keratin and collagen or their derivatives, calcium alginate, pullulan, agar, gelatin, tamarind seed polysaccharides, xanthan gum, carrageenan, high methoxyl pectin, low methoxyl pectin, guar gum, acacia gum, crystalline cellulose, arabinogalactan, karaya gum, tragacanth gum, alginic acid, albumin, casein, curdlan, β-glucan, gellan gum, dextran, acrylate crosspolymer, hydrophobic modified alkylcellulose, and the like. One or more of these may be used. When the cosmetic composition of the present invention contains a thickening agent other than hydrophobic modified polyether urethane, the content of the thickening agent other than hydrophobic modified polyether urethane is not particularly limited and can be adjusted according to the purpose.

[0029] <Description of the components of the hair dye composition of the present invention, part 3> As for polyglycerol fatty acid esters, component (a) polyglycerol fatty acid ester is a polyglycerol fatty acid ester in which the fatty acid is ester-bonded to (n) at a rate of 50-200% relative to the average degree of polymerization (n) of polyglycerol. More preferably, the polyglycerol fatty acid ester is formed in which the fatty acid is ester-bonded to 100-200% of the average degree of polymerization (n) of polyglycerol. For example, in the case of polyglyceryl-2 tetraisostearate, the average degree of polymerization (n) of polyglycerol is 2, and the ester-bonded fatty acid is 4, so the fatty acid relative to the average degree of polymerization (n) of polyglycerol is calculated as 4 / 2 = 200%. Furthermore, the fatty acid of the polyglycerol fatty acid ester is isostearic acid or oleic acid.

[0030] <Description of the components of the hair dye composition of the present invention, part 4> The (A) hydrophobic modified polyether urethane used in the present invention is a thickening agent such as a urethane copolymer having a hydrophilic base as its backbone and a hydrophobic portion at its ends. It is believed that these hydrophobic modified polyether urethanes exhibit a thickening effect when the hydrophobic portions of the copolymer associate with each other in a water-soluble medium, causing the hydrophilic portions to form loop-like or bridge-like structures. The hydrophobic modified polyether urethane that can be used in the present invention is not limited to known hydrophobic modified polyether urethanes, but for example, a hydrophobic modified polyether urethane obtained by reacting a polyoxyalkylene having 2 to 4 carbon atoms with a polyisocyanate having 2 or more isocyanate groups in the molecule and, if necessary, a polyoxyalkylene alkyl ether, alkylglyceryl ether, etc. can be used. In the present invention, commercially available hydrophobic modified polyether urethanes can be used, for example, Adekanol GT-700, Adekanol GT-930 (both manufactured by ADEKA Corporation), etc.

[0031] <Further explanation of examples of hair dye compositions> The hair dyeing composition according to the present invention will be described below. The hair dyeing composition according to the present invention is a hair dyeing composition comprising one or more dyes from among HC dyes, basic dyes, nitro dyes (direct dyes), and acid dyes. However, the amount of the dye (when using the hair dyeing composition) is greater than 0.0% by mass (0.0% by mass means that there is at least a small amount of something other than unavoidable impurities, for example, 0.0001% by mass or more, which is within the detection limit by a normal method; the same applies hereinafter and will be omitted) and 1.0% by mass or less, more preferably 0.01% by mass or more and 0.8% by mass or less (because if it exceeds 1.0% by mass, there is a risk of the dye precipitation).

[0032] When designing a color shampoo as described above, it is sufficient that the sample contains one or more of the following: cationic surfactants, anionic surfactants, amphoteric surfactants, or nonionic surfactants.

[0033] The hair dye composition according to the present invention preferably has a pH of 4.00 to 7.00, but if the hair dye composition is made by blending one or more of HC Blue 16, Basic Yellow 87, Basic Orange 31, and Basic Red 51, a pH of 7.00 or higher is also acceptable.

[0034] Furthermore, by including a penetration enhancer and a hair protectant in the hair dyeing composition according to the present invention, a more desirable additive effect tends to be exhibited, namely, the effect of being able to dye the hair while being gentle on it.

[0035] Examples of penetration enhancers include 1,3-butylene glycol, dilauroyl glutamate lysine sodium, cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol, and urea. These can be used individually or in combination of two or more as needed. However, other penetration enhancers may also be used.

[0036] Examples of hair protectants include keratin such as N-[2-hydroxy-3-(trimethylammonio)propyl]hydrolyzed keratin chloride solution and N-[2-hydroxy-3-(lauryldimethylammonio)propyl]hydrolyzed keratin chloride solution. However, other hair protectants may also be used.

[0037] Furthermore, the hair dyeing composition according to the present invention may contain, if necessary, one or more of ammonium bicarbonate, aqueous ammonia, and citric acid as pH adjusters for the purpose of improving dye adhesion and pH stability.

[0038] The hair dye composition according to the present invention preferably contains acid dyes, basic dyes, HC dyes, direct dyes, etc., as pigments or dyes, which can be used alone or in combination of two or more as needed. By including these pigments or dyes, it is possible to dye hair in a wide variety of colors.

[0039] Examples of acid dyes include those designated by Ministry of Health and Welfare Ordinance No. 30, "Ordinance Specifying Tar Dyes That Can Be Used in Pharmaceuticals, etc.," promulgated on August 31, 1966. The dyes used are not particularly limited to acidic dyes that are commonly used in hair dyes, such as 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. Examples include 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, Black No. 401, etc.

[0040] Basic dyes are not particularly limited to any basic dyes that can be commonly used in hair dyes, and examples include Basic Blue 124, Basic Blue 75, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Orange 31, Basic Red 51, Basic YELLOW 87, and Basic VIOLET 2.

[0041] HC dyes are not particularly limited as long as they are HC dyes that can be commonly used in hair dyes. Examples include HC Blue No. 2, HC Blue No. 5, HC Blue No. 6, HC Blue No. 9, HC Blue No. 10, HC Blue No. 11, HC Blue No. 12, HC Blue No. 16, HC Orange No. 1, HC Orange No. 2, HC Orange No. 31, HC Red No. 1, HC Red No. 3, HC Red No. 7, 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. 6, HC Yellow No. 9, HC Yellow No. 10, HC Yellow No. 11, etc.

[0043] The content of the aforementioned pigments and dyes is preferably 2% by weight or less, and more preferably 0.01 to 1% by weight. Exceeding 2% by weight tends to have a greater impact on viscosity.

[0044] Furthermore, the hair dye contained in the hair dye composition according to the present invention may contain various ingredients commonly used in cosmetics and hair dyes, to the extent that they do not impair the effects of the present invention.

[0045] For example, surfactants include, Stearyltrimethylammonium chloride, Tri(polyoxyethylene)stearylammonium chloride (5E.O.), Cationic surfactants such as cetyltrimethylammonium chloride, Sodium tetradecenesulfonate solution, Sodium lauroylmethyl-β-alanine solution, Anionic surfactants such as polyoxyethylene alkyl (12,13) ​​ether sodium sulfate (3E.O.), Alkyl polyglucoside, Polyoxyethylene castor oil, Nonionic surfactants such as polyoxyethylene hydrogenated castor oil, 2-Alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, Coconut oil fatty acid amidopropyl betaine solution, Examples of amphoteric surfactants include lauric acid amidopropyl betaine solution.

These can be combined in any way as needed (for example, as in the examples) by adding one or more of them as appropriate.

[0047] Needless to say, the storage container for the hair dye composition according to the present invention is not particularly limited.

[0048] <Specific Examples (Variations) and Comparative Examples)> The hair dyeing compositions according to the present invention will be described in detail below with reference to examples and comparative examples. The values ​​in the table represent mass percent. Furthermore, the mass percentages for each example are merely representative values. Based on the inventor's past experiments, we are empirically confident that any values ​​(mass%) within the range of 20% to 200% of the listed values ​​will exhibit at least the same properties. When taking a narrow margin, Based on the inventor's past experiments, he is empirically confident that materials exhibiting nearly identical properties will fall within a range of 50% to 150% of the listed values ​​(in terms of mass). Furthermore, the inventor is empirically confident from past experiments that materials within a range of 80% to 120% of each listed numerical value (in terms of mass) will exhibit virtually identical properties, making them indistinguishable.

[0049] Comparative Example 1, shown in Table 1, is a hair color treatment prepared with HC dyes and basic dyes, and Comparative Example 2 is an aqueous solution of Comparative Example 1. Example 1 is an example study in which hydrophobic modified polyether urethane is added to Comparative Example 2.

[0050] Furthermore, Comparative Example 3, shown in Table 2, is a weakly viscous comparative example sample prepared with HC dyes and basic dyes. Example 2 is an example sample in which hydrophobic modified polyether urethane is added to Comparative Example 3. Example 3 is an example sample in which polyglycerin fatty acid ester is added to Example 2.

[0051] Furthermore, Comparative Example 4, shown in Table 3, is an example sample 4 or 5 that differs from Comparative Example 1 in its dye combination, and is formulated with hydrophobic modified polyether urethane and polyglycin fatty acid ester, similar to Table 2. Here, Comparative Example 5 is an aqueous solution containing an acidic dye, and Example 7 is an example sample in which a hydrophobic modified polyether urethane is added to Comparative Example 5.

[0052] Comparative Example 6, shown in Table 4, is a hair color shampoo prepared with a basic dye, while Examples 8 and 9 are example samples containing hydrophobic modified polyether urethane and polyglycerin fatty acid ester, similar to those shown in Table 2.

[0053] The amount of dyes (HC dyes, basic dyes, direct dyes, and acid dyes) in each sample used for the examples is greater than 0.0% by mass and less than or equal to 1.0% by mass.

[0054] Here, we compare Samples 1-9 for the Examples and Samples 1-6 for the Comparative Examples, following the table provided. [Hair dyeing stability test method] Approximately 2g of each sample was applied to 1g of goat hair and yak hair (manufactured by Beaulux Co., Ltd.) bundles, each approximately 10cm long. After letting it stand for 10 minutes, it was rinsed with running water at approximately 40°C for 30 seconds and then air-dried. [Skin stain test method] Comparative sample and example sample were applied to the skin, left for 3 minutes, and then rinsed off with running water at approximately 40°C. [Method for testing for soiling] For stain tests on bathtubs and washbasins, comparative and example samples were applied, left for 10 minutes, and then rinsed off with running water at approximately 40°C.

[0055] [Evaluation Method] <Stability> Dyed goat hair and yak hair bundles were visually inspected to compare dye absorption and color unevenness due to hair quality, and the stability of dyeing based on hair quality was compared. Both strands of hair were dyed evenly and consistently. It is stained. I notice uneven coloring due to the hair texture. It was evaluated using [the method described]. <Skin stains> In the skin stain test, the sample is applied to the skin, and the stain (adhesion) after washing is compared. The stains are gone ◎ The stains were removed to an extent that they are no longer noticeable. There are still stains remaining. The determination was made using the method described above. <Stains> In the stain test, the degree of staining (adhesion) after washing off the sample attached to the object is compared. The stains are gone ◎ The stains were removed to an extent that they are no longer noticeable. There are still stains remaining. The determination was made using the method described above.

[0056] <Evaluation Results> As shown in the table, the examples combining hydrophobic modified polyether urethane and dyes exhibited stable dyeing properties regardless of the type of hair bundle, and it was found that staining of the skin and the degree of staining of samples attached to objects were significantly suppressed compared to the comparative examples. In comparisons with color treatments and color shampoos, it was found that staining of the skin and contamination of objects with the sample were significantly suppressed. This indicates that, regardless of the formulation, designing a combination of hydrophobic modified polyether urethane and dyes can produce a stain-suppressing effect on both skin and materials. Therefore, the present invention, as a hair dyeing composition, has a greater stain-inhibiting effect than conventional color treatments and color shampoos, and is able to suppress staining on the skin and on bathtubs and washbasins, which could not be solved with conventional products. [Industrial applicability]
