Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments and can be variously modified and implemented within the scope of the gist of the invention.

[0012] The hair dye fading prevention composition of the present disclosure (sometimes simply referred to as "composition") contains at least one first compound selected from specific L - ascorbic acid derivatives and their salts, and a cationic second compound.

[0013] Although not limited by theory, it is considered that the mechanism by which such a composition can reduce or suppress the fading of hair after hair dyeing is as follows.

[0014] Generally, hair is hydrophobic because its surface is covered with a cuticle. However, for example, when hair is damaged and the surface cuticle structure collapses, the damaged part becomes hydrophilic and is also known to be negatively charged.

[0015] And it is considered that the fading of dyed hair is affected by the hair being damaged, and as a result, the dye falls off from the damaged part by shampooing or the like.

[0016] The first compound and the second compound contained in the composition of the present disclosure are each known to be used as a repair agent for damaged hair and have the effect of repairing hydrophilic damaged hair and returning it to hydrophobicity. However, applying each of the first compound or the second compound alone to dyed hair could not prevent fading after shampooing. However, unexpectedly, the present inventors have found that when the first compound and the second compound are used in combination, fading after shampooing of dyed hair can be preferably prevented. The reason why the combination system of the first compound and the second compound can preferably prevent fading after shampooing of dyed hair is considered as follows.

[0017] The first compound reacts with an amino group present on the surface of undamaged hair, and a hydrophobic group based on a group constituting the first compound, for example, a linear or branched saturated or unsaturated fatty acid residue having 8 to 36 carbon atoms, is arranged to cover the surface of the hair, and the performance of repairing the hair surface to be hydrophobic can be exhibited. In addition, the cationic second compound is positively charged and is arranged to directly repair the damaged part of the negatively charged hair surface by a charge attraction action.

[0018] When the dye has fallen out of the damaged part of the hair due to shampoo or the like, the falling out of the dye from the hair seems to be dealt with only by directly repairing the damaged part with the second compound. However, since shampoo generally exhibits anionic properties, it is considered that the cationic second compound arranged in the repaired part is also attracted to some extent from the damaged part to the shampoo side. As a result, a cavity is formed in the repaired part where the dye falls out, and it is considered that sufficient fade prevention property is not exhibited.

[0019] On the other hand, in the composition of the present disclosure, first, the damaged part of the hair is repaired with the cationic second compound, and further, the amino group existing around the damaged part reacts with the first compound, and the repaired part by the second compound is considered to be covered and protected by the hydrophobic group brought about by the reaction of the first compound and the amino group. As a result, the cationic second compound protected by the hydrophobic group is retained without falling out of the damaged part even when shampooed, so it is considered that sufficient fade prevention property can be exhibited.

[0020] 《Composition for preventing hair dye fading》 The composition for preventing hair dye fading of the present disclosure has the performance of reducing or suppressing the fading of dyed hair (this performance may be simply referred to as "fade prevention property"). Regarding the fade prevention property, for example, according to the conditions of the fade prevention test described later, for dyed hair, the color of the hair before and after shampooing with shampoo is measured using a spectrophotometer, and the color difference (ΔE * ab ) can be used for evaluation. The closer the color difference (ΔE * ab ) is to zero, the more excellent the fade prevention property. This color difference (ΔE * ab ) can be 7.0 or less, 6.7 or less, 6.5 or less, 6.3 or less, or 6.0 or less. There is no particular limitation on the lower limit value of the color difference (ΔE * ab ), but for example, it can be 1.0 or more, 1.5 or more, 2.0 or more, 2.5 or more, 3.0 or more, 3.5 or more, or 4.0 or more.

[0021] 〈First Compound〉 The hair dye fading prevention composition of the present disclosure contains at least one first compound selected from L-ascorbic acid derivatives represented by the following formula 1 and salts thereof.

[0036] In the case of the monoalkyl-type quaternary ammonium salt, in formula 2, R 4 is preferably a linear or branched alkyl group having 8 to 22 carbon atoms. Such a number of carbon atoms is more preferably 12 or more or 16 or more, and is more preferably 20 or less or 18 or less. Also, R 4 is preferably a linear alkyl group.

[0039] Specific examples of the monoalkyl type quaternary ammonium salt include, for example, alkyltrimethylammonium chlorides such as behenyltrimethylammonium chloride, stearyltrimethylammonium chloride, and cetyltrimethylammonium chloride. Among them, from the viewpoint of anti-fading property and the like, behenyltrimethylammonium chloride and stearyltrimethylammonium chloride are preferred, and stearyltrimethylammonium chloride is more preferred.

[0040] (Dialkyl type quaternary ammonium salt) In the case of the dialkyl type quaternary ammonium salt, in Formula 2, R 4 and R 5 may be the same or different, and are preferably alkyl groups having 8 to 24 carbon atoms which may be substituted with a hydroxy group.

[0044] 〈Optional Component〉 In the hair dyeing and fading prevention composition of the present disclosure, various components can be appropriately blended as long as the effects of the present invention are not affected. For example, dyes, alkali agents, oxidizing agents, oils and fats agents, sequestering agents (for example, EDTA), stabilizers such as antioxidants (for example, vitamin C, cystine, sulfite), bactericides, preservatives, ultraviolet absorbers, solvents (for example, ethanol), water, penetrants (for example, benzyl alcohol), surfactants (for example, anionic surfactants, cationic surfactants other than the above, amphoteric surfactants, nonionic surfactants), water-soluble polymer compounds, moisturizers, conditioning agents (for example, polyols, keratin proteins, silicones, amino acids, plant extracts), pH adjusters (for example, phosphoric acid, citric acid, glycolic acid, lactic acid), gloss imparting agents, touch improvers, emollients, thickeners (cellulose, xanthan gum), solubilizers (for example, polyoxyethylene sorbitan monolaurate), pigments, fragrances, and the like. These optional components can be used alone or in combination of two or more.

[0045] For example, a composition further containing a dye can be used, for example, as a one-component temporary hair dye or semi-permanent hair dye, or as the first component of a two-component permanent hair dye. Note that the composition for preventing hair dye fading of the present disclosure can exhibit fading prevention properties for hair dyed with any of temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes. However, it is advantageous to use it for semi-permanent hair dyes and permanent hair dyes in which the dye penetrates into the interior of the hair and easily migrates from the damaged part of the hair to the outside by shampooing, and among them, for hair dyed with a permanent hair dye.

[0046] For example, when the composition is used as the first component of a two-component permanent hair dye, an alkaline agent can be further blended.

[0047] In addition, for example, a composition further containing an oxidizing agent can be used as the second component of a two-component permanent hair dye, and a composition further containing a persulfate can be used, for example, as the third component (bleaching agent) of a three-component permanent hair dye. Such a third component is an agent for bleaching the hair before hair dyeing, and after using this third component, a hair dyeing treatment is performed.

[0048] In addition, a surfactant, an oily agent, water, etc. can be appropriately blended with the composition and used as a hair conditioner, hair rinse, or hair treatment. Even if the composition for preventing hair dye fading of the present disclosure is not directly used as an agent for hair dyeing, by continuously using it in the form of a hair conditioner or the like, the discoloration of dyed hair can be reduced or suppressed.

[0049] Some components with high usage frequency among the optional components are described in detail below.

Preferred alkaline agents include ammonia, ammonium salts, and alkanolamines. These alkaline agents can be used alone or in combination of two or more.

[0066] (Oxidizing agent) In some embodiments, the composition for preventing hair dye fading of the present disclosure may contain an oxidizing agent. The oxidizing agent has the function of promoting the decolorization of melanin pigments in the hair, and can also exert the effect of oxidatively polymerizing the oxidation dye intermediate and any coupler to determine the coloring effect.

[0067] There is no particular limitation on the compounding amount of the oxidizing agent. For example, it can be 0.1% by mass or more, 0.5% by mass or more, or 1.0% by mass or more based on the total amount of the composition, and it can also be 12% by mass or less, 9.0% by mass or less, or 6.0% by mass or less.

[0068] There are no particular restrictions on the oxidizing agent.

These can be used alone or in combination of two or more.

[0069] (Oil and fat agent) In some embodiments, the composition for preventing hair dye fading of the present disclosure may contain an oil and fat agent. The oil and fat agent can be formulated in the composition, for example, to improve the coating performance, to exhibit the feeling of use (e.g., moist feeling), to exhibit the emollient effect on the hair, and the like.

[0070] There are no particular restrictions on the blending amount of the oil and fat agent. For example, it can be 0.1% by mass or more, 0.5% by mass or more, 1.0% by mass or more, 3.0% by mass or more, or 5.0% by mass or more based on the total amount of the composition, and can also be 20% by mass or less, 18% by mass or less, 15% by mass or less, 13% by mass or less, or 10% by mass or less.

[0071] There are no particular restrictions on the oil and fat agent. For example, oily components such as higher alcohols, higher fatty acids, and hydrocarbon oils can be mentioned. These can be used alone or in combination of two or more.

[0072] Examples of the higher alcohol include linear alcohols such as lauryl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, myristyl alcohol, oleyl alcohol, and cetostearyl alcohol; branched-chain alcohols such as isostearyl alcohol, monostearyl glycerin ether (batyl alcohol), 2-decyltetradecynol, lanolin alcohol, cholesterol, phytosterol, hexyl dodecanol, isostearyl alcohol, and octyldodecanol.

[0074] Examples of the hydrocarbon oil include liquid paraffin, ozokerite, squalane, pristane, paraffin, ceresin, squalene, petrolatum, microcrystalline wax, and the like.

[0075] <Form of the composition> The form of the composition for preventing hair dye fading of the present disclosure is not particularly limited, and for example, forms such as liquid, gel, paste, cream, wax, etc. can be appropriately selected.

[0076] Among the above forms, a cream form is preferable. The cream composition is more likely to be retained on the hair than the liquid composition, and the first compound and the second compound in the composition of the present disclosure are more likely to be fixed to the surface or damaged part of the hair, so that the fading prevention property can be further improved.

[0077] As the viscosity (viscosity during application) of the cream composition, for example, in the state where the first agent and the second agent used in a two-component hair dyeing kit are mixed, from the viewpoint of ease of spreading on the hair, etc., it can be 10,000 mPa·s or more, 20,000 mPa·s or more, 30,000 mPa·s or more, 40,000 mPa·s or more, 45,000 mPa·s or more, or 50,000 mPa·s or more. There is no particular limitation on the upper limit value of the viscosity of the cream composition, and for example, from the viewpoint of ease of spreading on the hair, it can be 100,000 mPa·s or less, 80,000 mPa·s or less, 60,000 mPa·s or less, 55,000 mPa·s or less, or 50,000 mPa·s or less. Here, such viscosity is intended to be the viscosity measured at 2 rpm when using a B-type viscometer (RV type viscometer RVDVI+, manufactured by Brookfield, rotor number 6) in an atmosphere of 25°C.

[0078] The composition of the present disclosure may be in the form of an oil-in-water or water-in-oil emulsion prepared using water, a surfactant, an oil component, etc.

Here, for example, persulfate or the like may be further blended in the third agent.

[0086] In the above-described embodiments, the composition for preventing hair dyeing fading is configured as one agent, but such a composition may be configured as two or more agents.

[0087] <Dosage form> The above-described various agents can be appropriately formulated in a container such as a tube, and there is no particular limitation on the dosage form. For example, pump spray, aerosol spray, pump foam, aerosol foam, cream, gel, lotion, etc. can be mentioned. Among them, as described above, from the viewpoints of retention performance on hair, discoloration prevention performance, etc., at least, as the dosage form of the agent containing the composition of the present disclosure, a cream dosage form is preferable.

[0088] <Usage method> The various agents used in the above-described hair dyeing kit can be applied to the hair by known methods. For example, in the case of a two-agent type, the first agent and the second agent are mixed and applied to the hair, and after a predetermined time has elapsed, it can be carried out by rinsing. In the case of a three-agent type, for example, the first agent to the third agent can be mixed and carried out in the same manner.

Examples

[0089] Examples will be given below to explain the present invention in more detail, but the present invention is not limited thereto. In the following, unless otherwise specified, the blending amounts are shown in mass%.

[0090] 《Examples 1 to 7 and Comparative Examples 1 to 5》 The first agent (composition containing a dye) of the two-agent type hair dye of each formulation shown in Table 2 was prepared by a conventional method. Also, the second agent (composition containing an oxidizing agent) of the two-agent type hair dye of the formulation shown in the blending example of Table 1 below was prepared by a conventional method. Using these first agent and second agent, the following evaluations were carried out, and the results are shown in Table 2 and FIG. 1.

[0091] 〈Evaluation method〉 (Evaluation of decolorization prevention: color difference (ΔE * ab )) A decolorizing agent containing 60% by mass of ion-exchanged water, 8% by mass of anhydrous sodium metasilicate, 20% by mass of ammonium persulfate, and 12% by mass of 35% hydrogen peroxide solution was applied to 2 g of black hair strands, left at 31 ° C for 20 minutes, then washed with water and air-dried to prepare damaged hair.

[0092] A mixture prepared by uniformly mixing the first agent and the second agent was applied to the damaged hair, left at 31 ° C for 30 minutes, then washed with water and air-dried to prepare dyed hair, and the hue (a * 1, b * 1) and lightness (L * 1) of the dyed hair were measured using a spectrophotometer (CM-3600d, manufactured by Konica Minolta).

[0093] Next, the dyed hair was put into a container containing 5% shampoo solution, immersed at 40 °C for 30 minutes, then washed with water and air-dried to prepare shampoo-treated hair. Similarly, the hue (a * 2, b * 2) and lightness (L * 2) of the treated hair were measured.

[0094] Then, the obtained measurement results were introduced into Equation 3 below to calculate the color difference (ΔE * ab ). Note that when the color difference differs by about 1, it tends to be recognized that the color tone is clearly different visually:
