Description

Technical Field

[0001] The present invention relates to a composition for a cleaning agent and a cleaning agent. In particular, the present invention can reduce the number of times of washing the hair with a cleaning agent for washing the hair after a hair dyeing treatment (hair coloring), maintain the dyed state of the dyed hair (suppress fading), and further, a cleaning agent composition and a cleaning agent having a performance of removing skin-damaging components contained in a hair colorant.

Background Art

[0002] Conventionally, for example, in a hair dyeing treatment of hair with a hair colorant, it has been reported that skin diseases (skin damage) occur due to components contained in the hair colorant. As such skin diseases, for example, irritant contact dermatitis, allergic contact dermatitis, etc. are known.

[0003] And irritant contact dermatitis occurs when the chemical irritation strength of an irritant as a causative substance exceeds the tolerance of the skin, and the main symptoms include pain and itching.

[0004] Here, as causative substances of irritant contact dermatitis contained in a hair colorant, for example, hydrogen peroxide, etc. can be mentioned.

[0005] Also, allergic contact dermatitis appears as an allergy when contacting an allergen which is a causative substance. The main symptoms are the same as those of irritant contact dermatitis, such as pain and itching.

[0006] And as causative substances of allergic contact dermatitis contained in a hair colorant, for example, diamines, ammonia, ethanolamine, etc. are there. As diamines, there are phenylenediamine (p-phenylenediamine, o-phenylenediamine, etc.), para-aminophenol, toluene-2,5-diamine sulfate, etc., which are known as oxidation dye intermediates. Also, ammonia, ethanolamine, etc. are used as alkaline agents.

[0007] Hair colorants (oxidative hair dyes) are oxidative hair dyes consisting of a first solution containing an oxidative dye intermediate containing diamines such as phenylenediamine (p-phenylenediamine, o-phenylenediamine, etc.), para-aminophenol, and toluene-2,5-diamine sulfate, as well as an alkaline agent such as ammonia and ethanolamine, and a second solution containing an oxidizing agent such as hydrogen peroxide. Hair dyes using oxidative hair dyes have the advantage of high dyeing power because the oxidative dye intermediate penetrates deep into the hair cuticle, where it undergoes oxidative coupling to form pigments and dye the hair.

[0008] As described above, since skin diseases (skin disorders) have been reported to occur due to ingredients contained in hair dyes, shampooing with a cleansing agent is performed after hair treatment with hair dye.

[0009] Shampoos using this type of cleansing agent can damage the cuticle on the surface of the hair, leading to dryness, stiffness, breakage, and split ends after drying. Therefore, cleansing agents that cause less damage to the cuticle or that have conditioning effects are known.

[0010] As mentioned above, after hair coloring, the colored hair is washed (shampooed) after treatment with hair dye. However, multiple shampoos are often performed to thoroughly wash away the hair dye. Specifically, the first shampoo doesn't lather well, and lathering is only seen on the second shampoo, giving the impression that one shampoo is insufficient, hence the practice of multiple shampoos. Recently, some hair salons only shampoo once after hair coloring treatment, but as mentioned above, the hair still doesn't lather well with just one shampoo, so multiple shampoos (two or more) are still common.

[0011] As described above, shampooing after hair coloring is often done multiple times, but this can easily damage the hair and lead to problems such as scalp dryness due to over-washing. Furthermore, it can cause the dyed hair color to fade.

[0012] Therefore, it is desirable to reduce the number of times shampooing is done after hair coloring.

[0013] Furthermore, since color fading (which can also be described as the release of dye from the colored hair) occurs over time after hair coloring, hair cleansing products (hair cleansing products for hair coloring) that reduce this color fading have also been reported (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent Documents]

[0014] [Patent Document 1] Japanese Patent Publication No. 2017-19740 [Patent Document 2] Japanese Patent Publication No. 2020-164474 [Overview of the Initiative] [Problems that the invention aims to solve]

[0015] However, the hair cleansing agents described in Patent Documents 1 and 2 did not have sufficient cleansing power, and it was still necessary to shampoo multiple times to clean the hair to the desired degree after coloring.

[0016] Furthermore, since colored hair fades (discolors) due to daily shampooing, the hair washing products described in Patent Documents 1 and 2 are used to reduce color fading (suppress discoloration), but the effect tends to be insufficient. In other words, the dyed state is difficult to maintain sufficiently, and hair discoloration tends to progress.

[0017] Furthermore, hair cleansing products used to shampoo hair after hair coloring should ideally have high removal capabilities for skin-damaging components contained in hair colorants. However, the hair cleansing products described in Patent Documents 1 and 2 did not have sufficient performance in removing skin-damaging components.

[0018] Therefore, there was a need to develop a cleansing composition that could reduce the number of times the hair was washed with a cleansing product after hair dyeing, maintain the colored state of the dyed hair (suppressing fading) (in particular, suppressing fading even when using commercially available cleansing products (cleansing products that do not have a fading-suppressing effect) for daily shampooing after coloring), and furthermore, have the ability to remove skin-damaging components contained in hair colorants.

[0019] The present invention has been made in view of the problems of the prior art, and its objective is to provide a cleansing composition and cleanser that can reduce the number of times the hair is washed with a cleanser after hair dyeing, maintain the colored state of the dyed hair (suppress fading), and further have the ability to remove skin-damaging components contained in hair colorants.

[0030]

[0032]

[12] A cleansing agent containing the cleansing agent composition described in [1] or [2] above. [Effects of the Invention]

[0033] The cleansing composition of the present invention reduces the number of times the hair needs to be washed with a cleansing agent after hair dyeing, maintains the colored state of the dyed hair (suppresses fading), and further has the effect of removing skin-damaging components contained in hair colorants.

[0034] The cleansing agent of the present invention reduces the number of washes required when washing hair after hair dyeing, suppresses color fading in dyed hair, and further has the effect of removing skin-damaging components contained in hair colorants. [Brief explanation of the drawing]

[0035] [Figure 1] This is an explanatory diagram showing the hue "purple (P)" in the Munsell color system. [Figure 2] This is an explanatory diagram showing the hue "10PB" in the Munsell color system. [Modes for carrying out the invention]

[0036] The embodiments of the present invention will be described below, but the present invention is not limited to the embodiments described below. It should be understood that the scope of the present invention also includes modifications, improvements, etc., to the embodiments described below, made in accordance with the ordinary knowledge of those skilled in the art, without departing from the spirit of the invention.

[0037] (1) Cleansing composition: One embodiment of the detergent composition of the present invention contains a polyphenol, an organic compound having a carboxyl group, and a surfactant component selected from the group consisting of nonionic surfactants and cationic surfactants, wherein the polyphenol content is 0.00001 to 10.0% by mass, the organic compound content is 0.00001 to 5.0% by mass, and the surfactant component content is 0.01 to 50% by mass.

[0038] Such a cleansing composition can reduce the number of times the hair needs to be washed with a cleanser after hair dyeing. Furthermore, this cleansing composition maintains the colored state of dyed hair (inhibits fading). In addition, this cleansing composition has the ability to remove skin-damaging components contained in hair colorants.

[0039] In hair dyeing, the hair is washed with a cleansing agent after the dyeing process. However, with conventional cleansing agents, a single wash is often insufficient to thoroughly cleanse the hair. In other words, the wastewater is often heavily colored, indicating that the dye has not been completely removed. Therefore, two or more washes are frequently performed; that is, two or more sets of washing with the cleansing agent followed by rinsing are considered one set. While two or more washes are preferable in terms of thoroughly removing the dye from the hair, fewer washes are preferable from the viewpoint of maintaining the condition of the hair surface and the oil balance of the scalp. Furthermore, fewer washes reduce the workload for the stylist and the cost of the cleansing agent. With the cleansing agent containing the composition of the present invention, the dye can be thoroughly removed even with fewer washes, and the post-dyeing hair washing process can be completed.

[0040] Furthermore, since hair that has been dyed fades due to daily shampooing and sunlight, cleansing agents with a fade-inhibiting effect are often used. Cleansing agents containing the cleansing composition of the present invention can also suppress this hair fade. In addition, for example, even if the cleansing composition of the present invention is added to a cleansing agent that does not have a fade-inhibiting effect (such as a commercially available general shampoo) and shampooing is performed, hair fade can be suppressed. Moreover, it is recommended not to shampoo (wash hair at home, etc.) for several days after coloring in order to prevent fading, but if the cleansing composition of the present invention is used, fading due to shampooing is sufficiently suppressed, so shampooing can be done from the day of coloring.

[0041] Next, in this specification, "skin-damaging ingredient" means a substance that causes skin diseases such as irritant contact dermatitis and allergic contact dermatitis (such as those contained in hair dyes).

[0042] Irritant contact dermatitis occurs when the chemical irritation from an irritant exceeds the skin's tolerance level, and its main symptoms include pain and itching. Examples of irritants that can cause irritant contact dermatitis include hydrogen peroxide.

[0043] Allergic contact dermatitis is a condition that manifests as an allergic reaction upon contact with an allergen, which is the causative substance. The main symptoms are similar to those of irritant contact dermatitis, including pain and itching.

[0044] Furthermore, substances in hair dyes that cause allergic contact dermatitis include, for example, diamines, ammonia, and ethanolamine, which are compounds containing a positively ionized nitrogen atom. Examples of diamines include phenylenediamine (p-phenylenediamine, o-phenylenediamine, etc.), para-aminophenol, toluene-2,5-diamine sulfate, etc., and are known as intermediates for oxidation dyes. In addition, ammonia and ethanolamine are used as alkaline agents.

[0045] Here, the primary opportunity for skin-damaging components such as diamines to cause skin damage is during hair treatment with chemicals. For example, diamines, among the skin-damaging components, react with alkaline agents during hair treatment. However, after reacting with the alkaline agent, diamines that remain in the hair without becoming fixed (residual diamines) come into contact with the scalp and cause skin damage. Similarly, other skin-damaging components besides diamines can also cause skin damage if they remain in the hair and come into contact with the scalp. Therefore, it is desirable to wash away skin-damaging components such as diamines as soon as possible by washing the hair. Secondly, diamines that have become fixed to the hair due to chemical treatments such as hair dyeing can detach from the hair over time due to sweat and washing, and come into contact with the scalp, causing skin damage. This detachment of diamines from the hair due to sweat and washing after hair treatment can be seen, for example, when washing hair at home after hair treatment. Furthermore, if hair is not washed thoroughly (or if the washing technique is poor), skin-damaging components such as diamines may remain in the hair.

[0046] As described above, there are two main ways in which skin-damaging components such as diamines can come into contact with the scalp and cause skin damage. In either of these cases, reducing the residue and contact of skin-damaging components such as diamines with the scalp can suppress the occurrence of skin damage.

[0047] Therefore, according to the cleansing composition of the present invention, it is possible to reduce skin damage in hair coloring (hair dyeing treatment) using hair dyes, for example. Specifically, it is possible to capture skin-damaging components such as residual diamines and prevent these components from coming into contact with the skin (scalp). Furthermore, the cleansing composition of the present invention can reduce the amount of diamines that separate from the hair over time (securely fix the diamines to the hair during hair treatment), and by appropriately removing skin-damaging components remaining on the scalp, it is possible to suppress the occurrence of skin damage caused by diamines separating from the hair over time. In addition, by securely fixing the diamines to the hair, for example in the case of hair dyeing treatment, the color of the dyed hair is less likely to fade and the dyed state can be maintained (dye maintenance).

[0048] (1-1) Polyphenols: Polyphenols are a general term for compounds that have two or more phenolic hydroxyl groups. Most polyphenols are derived from plants.

[0049] The polyphenol is not particularly limited as long as it is the low-molecular-weight compound described above, but it can be a polyphenol having a 3,4-dihydroxyphenyl group or a polyphenol having a 3,4,5-trihydroxyphenyl group. With such a polyphenol, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, it exhibits even greater performance in removing skin-damaging components contained in hair colorants.

[0050] Polyphenols include monomeric polyphenols and polymeric polyphenols. Specifically, monomeric polyphenols include flavonoids and non-flavonoids. Polymeric polyphenols include condensation-type and hydrolysis-type polyphenols.

[0051] Examples of flavonoids include epicatechin (including cyanidin and procyanidin), epigallocatechin, epicatechin gallate, and epigallocatechin gallate. Examples of non-flavonoids include those having a carboxyl group, such as tannic acid, gallic acid, ellagic acid, flavogalonic acid, chlorogenic acid, caffeic acid, rosmarinic acid, and chicoriic acid.

[0052] Furthermore, polyphenols can be used as plant extracts containing these polyphenols. In other words, at least a portion of the polyphenols in this invention may be polyphenols contained in plant extracts.

[0053] Examples of such plant extracts include: green tea leaf extract, rooibos extract, Geranium thunbergii flower / leaf / stem extract, witch hazel leaf extract, lemon balm leaf extract, Melia azadirachta leaf extract, lavender flower / leaf / stem extract, perilla leaf extract, sage leaf extract, Swertia japonica extract, myrtle fruit extract, butterfly pea flower extract, comfrey leaf extract, hawthorn extract, sansho pepper peel extract, olive leaf extract, jujube fruit extract, arnica flower extract, ivy leaf / stem extract, watercress extract, and mallow. Flower extracts, grape leaf extract, rosemary leaf extract, turmeric extract, bilberry leaf extract, peony extract, strawberry fruit extract, chrysanthemum flower extract, onion root extract, lobster coffee tree seed extract, sausage flower extract, chamomile flower extract, butterbur leaf / stem extract, linden flower extract, purple coneflower extract, cistanche tubulosa root extract, evening primrose flower extract, evening primrose seed extract, mate leaf extract, burnet extract, Aristotelia chilensis fruit extract, etc. are examples, but are not limited to these.

[0054] The polyphenol (total polyphenol) content in this plant extract can be calculated using the Forinthiokart method, based on the equivalent amount of (+)-catechins.

[0055] Furthermore, in this invention, two or more types of polyphenols can be used in combination.

[0056] While there are no particular restrictions on the average molecular weight of polyphenols, they can be, for example, between 100 and 50,000, preferably between 200 and 30,000, and even better between 250 and 10,000. By incorporating one or more polyphenols that meet the above ranges, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced. The average molecular weight of polyphenols can be measured using methods such as size exclusion chromatography.

[0057] The polyphenol content is between 0.00001 and 10.0% by mass, can be between 0.00001 and 5.0% by mass, and can be between 0.00001 and 3.0% by mass, with a particularly good range being 0.0001 to 1.0% by mass. By setting the content within the above range, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0058] (1-2) Organic compounds: The organic compound is one that has a carboxyl group, and one having two or more carboxyl groups is particularly preferable. By including such an organic compound, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, it exhibits even greater performance in removing skin-damaging components contained in hair colorants. The upper limit for the number of carboxyl groups can be three.

[0059] Examples of organic compounds include tartaric acid, lactic acid, citric acid, succinic acid, maleic acid, dimaleic acid, fumaric acid, glycolic acid, glyoxylic acid, malic acid, gluconic acid, glyceric acid, arginine acid, sebacic acid, itaconic acid, citraconic acid, adipic acid, and azelaic acid.

[0060] The content of organic compounds is 0.00001 to 5.0% by mass, can be 0.00001 to 3.0% by mass, and preferably 0.00001 to 1.0% by mass. By setting the content within the above range, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0061] (1-3) Surfactant components: The surfactant component is selected from the group consisting of nonionic surfactants and cationic surfactants. By including such a surfactant component, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, it exhibits even greater performance in removing skin-damaging components contained in hair colorants.

[0062] (1-4a) Nonionic surfactants: Nonionic surfactants can be defined as having the following basic structures: polyoxyethylene alkyl ethers, polyoxyethylene stearyl ethers, polyoxyethylene fatty acid esters, polyoxyethylene polyhydric alcohol fatty acid esters, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbitan fatty acid esters, glycol fatty acid esters, glycerin fatty acid esters, sorbitan fatty acid esters, sucrose fatty acid esters, polyglycerin fatty acid esters, and polyoxyethylene dimethicone copolymers. Furthermore, nonionic surfactants can also be defined as compounds having glyceride and glycerin polymer skeletons, as exemplified later, and may include at least one selected from these groups.

[0063] Nonionic surfactants can have units with 24 or fewer carbon atoms in the lipophilic group, preferably units with 22 or fewer carbon atoms, and even better units with 20 or fewer carbon atoms. The lower limit of this carbon number can be around 1. Such nonionic surfactants can reduce the number of times the hair needs to be washed with a cleansing agent after hair dyeing, and furthermore, the colored state of the dyed hair is maintained (fading is suppressed). In addition, they further demonstrate the ability to remove skin-damaging components contained in hair colorants.

[0064] (1-3b) Cationic surfactants: Cationic surfactants are polymers composed of cationic monomer units having, for example, aliphatic primary amino groups, secondary amino groups, tertiary amino groups, quaternary ammonium groups, amidine groups, guanidine groups, and quaternary nitrogen-containing heterocyclic residues.

[0065] The surfactant content is 0.01 to 50% by mass, can be 0.01 to 40% by mass, and is even better set to 0.01 to 30% by mass. By setting it within the above range, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0066] The ratio of polyphenols to the total amount of surfactants containing nonionic surfactants (polyphenol / surfactant containing nonionic surfactant) can be 1.0 or less. Furthermore, it is preferable to set it to 0.5 or less, even better to set it to 0.00001 to 0.2, and particularly better to set it to 0.0001 to 0.15. By setting it within the above range, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced. Note that "surfactant" includes nonionic surfactants, and other than nonionic surfactants, it can refer to those similar to those conventionally known to be included in cleansing agents (shampoos).

[0067] (1-4) Terpenoid compounds: The cleansing composition of the present invention may further contain a terpenoid compound, the content of which may be 0.0000001 to 1.0% by mass. By including such a terpenoid compound, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, it exhibits even greater performance in removing skin-damaging components contained in hair colorants.

[0068] Examples of terpenoid compounds include monoterpenoids, sesquiterpenoids, diterpenoids, triterpenoids, and tetraterpenoids.

[0069] Monoterpenoids consist of 2 isoprene units, sesquiterpenoids of 3 isoprene units, diterpenoids of 4 isoprene units, and triterpenoids of 6 isoprene units. Tetraterpenoids, on the other hand, consist of 8 isoprene units.

[0070] Furthermore, the terpenoid compound may have a carboxyl group. In other words, a terpenoid compound having a carboxyl group in its molecule can be used. Such a terpenoid compound can reduce the number of times the hair needs to be washed with a cleansing agent after hair dyeing, and furthermore, the colored state of the dyed hair is maintained (fading is suppressed). It also further enhances the ability to remove skin-damaging components contained in hair colorants.

[0071] Examples of terpenoid compounds having a carboxyl group include camphoric acid, abietic acid, fusidic acid, helvonic acid, betulinic acid, glycyrrhizic acid, glycyrrhetinic acid, oleanolic acid, oleanonic acid, and ursolic acid.

[0072] The content of terpenoid compounds can be 0.0000001 to 1.0% by mass, and more preferably 0.0000001 to 0.5% by mass, and more preferably 0.0000001 to 0.25% by mass. By setting the content within the above range, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0073] Furthermore, the terpenoid compound may be one contained in a plant extract. In other words, a plant extract containing a predetermined amount of the above-mentioned terpenoid compound may be used instead of the terpenoid compound. Examples of such plant extracts include ginkgo leaf extract, plum fruit extract, ginseng root extract, olive leaf extract, orange juice, licorice root extract, sansho pepper peel extract, soapwort leaf extract, hawthorn extract, perilla leaf extract, sage leaf extract, swertia japonica extract, myrtle fruit extract, jujube fruit extract, bitter orange peel extract, loquat leaf extract, grape leaf extract, prune extract, lemon fruit extract, soapberry peel extract, lemon balm leaf extract, Melia azadirachta leaf extract, lavender flower / leaf / stem extract, apple peel extract, rosemary leaf extract, and Sanguisorba officinalis extract.

[0074] (1-5) Metals: The cleansing composition of the present invention may further contain metals, and "metals" refers to compounds that fall under any of the following categories: inorganic metals, organometallic compounds, and organic substances that form complexes with organometallic compounds (organometallic complexes). By including these metals, the number of times the hair needs to be washed with a cleansing agent after hair dyeing can be reduced, and the coloring state of the dyed hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0076] The metals used may include metals belonging to the fourth period of the periodic table, and furthermore, may not contain at least one of inorganic iron, inorganic silver, and inorganic copper. Using these metals reduces the number of times the hair needs to be washed with a cleansing agent after dyeing, and also maintains the colored state of the dyed hair (suppresses fading). Furthermore, it further enhances the ability to remove skin-damaging components contained in hair colorants.

[0077] The metal content can be between 0.000001 and 5.0% by mass, preferably between 0.000001 and 1.0% by mass, and even better between 0.000001 and 0.5% by mass. By setting the content within this range, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0082] There are no particular restrictions on the average molecular weight of compounds such as polyethylene glycol; its lower limit may be 100 or 300. For example, the upper limit for the average molecular weight of polyethylene glycol can be 10,000,000.

[0083] The content of polyethylene glycol and other compounds can be 0.00001 to 10% by mass, preferably 0.00001 to 5% by mass, and even more preferably 0.0001 to 5% by mass. By setting the content within the above range, the number of times the hair needs to be washed with a cleansing agent after dyeing can be reduced, and the dyed state of the hair is maintained (fading is suppressed). Furthermore, the ability to remove skin-damaging components contained in hair colorants is further enhanced.

[0084] (1-7) Other ingredients: The detergent composition of the present invention may further contain other components in addition to the above-mentioned components.

[0085] Other ingredients can be appropriately selected and added from those conventionally known for use in cleansing compositions. Examples include humectants, alcohols, film-forming agents, penetration enhancers, thickeners, pH buffers, preservatives, antioxidants, anionic surfactants, and chelating agents.

[0086] The content of other components can be 0.00001 to 50% by mass, preferably 0.0001 to 40% by mass, and even better 0.00001 to 30% by mass.

[0087] The cleansing composition of the present invention has no particular restrictions on its pH, but it can be a liquid with a pH of 8 or lower, and is preferably an acidic liquid. Specifically, it can be a liquid with a pH of 3 or higher and less than 7. A liquid with a pH of 8 or lower can reduce the number of times the hair needs to be washed with the cleansing agent after hair dyeing, and furthermore, the dyed state of the hair is maintained (fading is suppressed). It also further exhibits the ability to remove skin-damaging components contained in hair colorants. The term "liquid" above refers to a liquid fluid, and includes viscous substances, as well as gel-like and gel-like substances.

[0088] (2) Method for producing a composition for washing: The detergent composition of the present invention can be prepared by employing conventionally known methods as appropriate. Specifically, each component (polyphenol, terpenoid compound, and organic compound having a carboxyl group) was added to a mixing container under an atmosphere of 25°C to obtain a mixture. Then, a surfactant component dissolved in water at 50°C was added little by little to the surfactant solution, which had been allowed to cool to room temperature, to obtain a mixture. In this way, the detergent composition can be obtained.

[0089] (3) Use of cleansing compositions: The cleansing composition of the present invention can be used in cleansing products for washing hair after hair coloring, and can be used as an additive to be added to the cleansing product itself, or it may be included in the cleansing product beforehand. When used as an additive, it may be mixed with the cleansing product before shampooing, or it may be added to the hair during shampooing.

[0090] (4) Cleansing agent: The cleansing agent of the present invention contains the cleansing composition of the present invention described above. This cleansing agent can reduce the number of washes required when washing hair after hair dyeing. Furthermore, it can suppress color fading in dyed hair. In addition, this cleansing agent has the ability to remove skin-damaging components contained in hair colorants.

[0091] Furthermore, while the cleansing agent of the present invention can suppress color fading in dyed hair even when used only as a shampoo after hair dyeing, it can also be used as a daily shampoo after hair dyeing. Doing so can further suppress color fading in dyed hair.

[0092] The detergent of the present invention can appropriately use the same components as those used in conventionally known detergents.

[0093] The detergent of the present invention can be manufactured by producing a detergent main component in the same manner as conventionally known detergents, and then adding the detergent composition of the present invention to this detergent main component. Alternatively, the detergent of the present invention may be manufactured by mixing the components of the detergent composition of the present invention together with the components of conventionally known detergents, without producing a detergent main component. [Examples]

[0094] The present invention will be described in detail below based on examples, but the present invention is not limited to these examples.

[0095] (Examples 1-82, Comparative Examples 1-16) Detergent compositions were prepared by blending each component and its proportion (mass%) as shown in Tables 1 to 10. Subsequently, the prepared detergent compositions were added to commercially available detergents to create test detergents (shampoos containing treatment solutions). These test detergents were used as appropriate to perform the following evaluations (ease of washing, color fading suppression, and firmness / body).

[0096] (Precipitation of skin-damaging components) An alkaline diamine oxide solution (paraphenylenediamine 0.5%, monoethanolamine 10ml, ammonia 5ml, hydrogen peroxide 3.5%, ethanol 30%, residue water, pH 10), which is a model solution for hair colorants, was added to 5ml of each treatment solution to prepare the test solution. After standing for 5 hours, the presence or absence of precipitate in the test solution was visually checked. If precipitate was observed, it was marked as "OK," and if no precipitate was observed, it was marked as "NG."

[0097] The confirmation of precipitation in this evaluation means that the treatment solution has captured skin-damaging components, including diamines, in the diamine oxide solution (hair colorant model solution). Therefore, if the product is in the hair, it can prevent skin-damaging components such as diamines from coming into contact with the scalp. Furthermore, this precipitate containing the captured skin-damaging components will be washed away by shampooing. As a result, skin damage (such as scalp inflammation and allergies) caused by skin-damaging components such as diamines can be reduced when using hair colorants.

[0098] (Reaction rate (precipitation formation time)) The time it took for precipitates (containing skin-damaging components such as diamines) to form (reaction rate) was evaluated by visual inspection. The evaluation criteria were as follows:

[0099] If precipitate is observed within 1 minute of the start of the reaction, it is classified as "SS"; if precipitate is observed more than 1 minute but within 5 minutes of the start of the reaction, it is classified as "S"; if precipitate is observed more than 5 minutes but within 1 hour of the start of the reaction, it is classified as "A"; if precipitate is observed more than 1 hour but within 3 hours of the start of the reaction, it is classified as "B"; and if precipitate is observed more than 3 hours after the start of the reaction, it is classified as "C". "Precipitation" is defined as the formation of a layer at the bottom of the test tube (10 ml) with a thickness of 1 mm or more.

[0100] This evaluation further assesses the removal rate of components contained in the diamine solution. In other words, for hair coloring performed in salons or at home, it is desirable to capture a large amount of skin-damaging components, including diamines, in a short amount of time. The observation of precipitation in a short time in this evaluation means that a large amount of skin-damaging components can be captured in a short amount of time.

[0101] (Ease of washing hair) One gram of gray hair was prepared as test hair. A mixture of level 1 hair color agent 1 and 6% hydrogen peroxide agent 2 was applied to this hair, left for 20 minutes to dye it, and then rinsed with running water for 1 minute.

[0102] Subsequently, the dyed gray hair (test hair) was washed for 1 minute with the prepared treatment solution-containing shampoo, and then rinsed with running water for 1 minute. In other words, one shampooing cycle was performed.

[0103] Furthermore, in all cases of hair washing with the shampoo containing the treatment solution, sufficient lathering was achieved on the test hair.

[0104] Next, 200 ml of water was placed in a 500 ml container, and the test hair was rinsed in the container for 1 minute. The color of the water (washing wastewater) in the container after 1 minute was checked. The process from shampooing to rinsing in the container was repeated until the washing wastewater became colorless, and the number of times this process (hair washing) was performed was counted. The washing wastewater was discarded each time the color after rinsing in the container was checked, and fresh water was placed in the container for rinsing. The less color fading after shampooing (i.e., fewer washing sessions) indicated that hair washing was less troublesome, and therefore the ease of washing was judged to be high (i.e., hair washing was easy).

[0105] The criteria for evaluating ease of washing hair were as follows: If no colored water was produced after the first color fading check (i.e., the wastewater from the first wash was colorless), the ease of washing hair was rated "S"; if no colored water was produced after the second color fading check, the ease of washing hair was rated "A"; if no colored water was produced after the third color fading check, the ease of washing hair was rated "B"; if no colored water was produced after the fourth color fading check, the ease of washing hair was rated "C"; and if colored water was still produced after the fourth color fading check, the ease of washing hair was rated "D". Using the Munsell system purple shown in Figure 1, a value of 9 and a saturation of 2 or less (i.e., the wastewater from the wash was lighter than 9 and 2) was considered "no colored water was produced". A rating of B or higher suggests that the hair color can be sufficiently washed out with about one shampoo after actual hair coloring.

[0106] In actual hair salons, shampooing is usually done twice, and it is rare to shampoo three or more times. This is not because two shampoos eliminate the colored water, but because three or more shampoos can cause greater problems for the scalp and hair, and also because it takes into consideration the increased treatment time and costs associated with shampooing.

[0107] (Suppressing fading) One gram of gray hair was prepared as test hair. A mixture of level 1 hair color agent 1 and 6% hydrogen peroxide agent 2 was applied to this hair and left for 20 minutes to dye it. After that, the hair was washed with a commercially available shampoo, and the rinsing and drying process was repeated 10 times (10 sets), after which the hair color was judged.

[0108] The evaluation criteria for determining hair color (fading suppression) were as follows: Using the Munsell 10PB system shown in Figure 1, a lightness of 3 or less and a saturation of 1 were designated as "S", a lightness of 3 or less and a saturation of 2 as "A", a lightness of 3 or less and a saturation of 3 as "B", a lightness of 4 and a saturation of 4 as "C", and a lightness of 6 and a saturation of 6 or less as "D".

[0109] (firmness and resilience) The hair was washed in the same manner as the evaluation of ease of washing, and then thoroughly dried with a hairdryer. After that, while holding the ends of the hair, the entire hair was positioned at a 45-degree angle to the horizontal plane (horizontal table surface) (reference state). Then, while fixing the roots of the hair, the ends were released. In this state, the ends of the hair hang down, so a straight line L connecting the roots and ends of the hair was imagined, and the angle between this line L and the horizontal plane (horizontal table surface) (angle after release) was measured. The angle difference θ, which is the difference between the angle of the hair in the reference state (45°) and the angle after release (45° - angle after release (°)), was then measured.

[0110] The evaluation criteria for firmness and resilience were as follows: An angle difference θ of 5 degrees or less was designated as "S", an angle difference θ of more than 5 degrees but 10 degrees or less was designated as "A", an angle difference θ of more than 10 degrees but 15 degrees or less was designated as "B", and an angle difference θ of more than 15 degrees was designated as "C".

[0111] (stability) The treatment solution used for evaluating "precipitation of skin-damaging components" was allowed to stand for one hour, and its condition was visually inspected. The stability of the treatment solution (liquid storage capability) was evaluated according to the following criteria: "S" if it remained in a clear, solubilized state, "A" if it was slightly cloudy, "B" if some precipitate was present, and "C" if large precipitates were formed.
