Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic emulsion comprising an aqueous phase (AP) that forms a continuous phase of the hair cosmetic emulsion and an oil phase (OP) that forms a dispersed phase of the hair cosmetic emulsion, wherein the hair cosmetic emulsion comprises a plant mixture (BM) containing nine plant components: bamboo extract, cactus extract, jojoba oil, safflower oil, olive oil, babassu oil, sesame seed oil, rice bran oil, and evening primrose oil. The present invention further relates to a method of treating human hair using the hair cosmetic emulsion, and to the use of the hair cosmetic emulsion for the treatment of human hair, particularly for hair nourishment and / or strengthening of human hair, or for the protection of human hair from contamination. [Background technology]

[0002] Human hair becomes dirty due to contact with the surrounding environment and sebum secreted from the scalp. When hair becomes dirty, it looks unclean and loses its attractiveness. When hair becomes dirty, it needs to be shampooed frequently and regularly.

[0003] Shampooing cleanses hair by removing excess dirt and sebum. However, shampooing can leave hair wet, tangled, and generally unmanageable. Once hair dries, its natural oils, other natural conditioning and moisturizing components are removed, often leaving it dry, rough, dull, or frizzy. Furthermore, increased static electricity levels may remain after drying, hindering combing and resulting in what is commonly referred to as "fly-away" hair or contributing to the undesirable phenomenon of "split ends."

[0004] Furthermore, chemical treatments such as hair perms, bleaching, or coloring can also damage the hair and may leave it dry, frizzy, dull, and damaged. Additionally, hair can be damaged by ultraviolet rays and heat.

[0005] To condition hair, various approaches have been developed. A common way to impart conditioning benefits to hair is by using conditioning agents such as cationic surfactants and high melting point fatty compounds, silicone compounds, and mixtures thereof.

[0006] In particular, silicone compounds have been overly used over the past few decades to provide conditioners with enhanced benefits such as hair shine, softness, smoothness of dry hair, alignment of hair bundles (e.g., minimizing frizz), and ease of combing.

[0007] However, consumers are becoming more aware of the safety of the ingredients used in their cosmetics, particularly the use of synthetic compounds that raise questions about toxicity and environmental impact.

[0008] Therefore, there is a need for keratin fiber treatments that do not contain ingredients with questionable toxicity and environmental impact.

[0009] Furthermore, there is a need for hair cosmetics that can protect keratin fibers, especially human hair, from heat up to 230°C, ultraviolet rays, and the accumulation of contaminants on the hair. SUMMARY OF THE INVENTION

[0010] An object of the present invention is to provide a composition that can condition and protect human hair. The composition for conditioning and protection preferably can protect keratin fibers, especially human hair, from heat up to 230°C, ultraviolet rays, and / or the accumulation of contaminants on the hair.

[0011] This object is solved by a hair cosmetic emulsion comprising a plant mixture (BM) containing nine plant components.

[0012] Thus, in one aspect, the present invention relates to a hair cosmetic emulsion comprising an aqueous phase (AP) forming the continuous phase of the hair cosmetic emulsion, and an oil phase (OP) forming the dispersed phase of the hair cosmetic emulsion, wherein the hair cosmetic emulsion b1) bamboo extract, b2) cactus extract, b3) jojoba oil, b4) safflower oil, b5) olive oil, b6) babassu oil, b7) sesame seed oil, b8) rice bran oil, and b9) evening primrose oil and targets a hair cosmetic emulsion containing a plant mixture (BM) comprising nine plant components.

[0013] Surprisingly, it has been found that the hair cosmetic emulsion containing the plant mixture (BM) can protect and condition human hair. Furthermore, the hair cosmetic emulsion containing the plant mixture (BM) has been surprisingly found to provide one, two or all of the advantages of heat protection up to 230 °C, protection from ultraviolet rays, prevention of split ends, prevention of frizzy hair, prevention of accumulation of contaminants on the hair, and prevention of curly hair.

[0014] Furthermore, the hair cosmetic emulsion containing the plant mixture (BM) can supply nutrients to human hair, give moisture, and serve as a moisture shield.

[0015] The present invention is effective in providing the advantages of hair protection and conditioning to hair damaged by natural environmental factors such as shampooing, and chemical treatments to the hair such as bleaching, coloring or perming. Detailed Description of the Invention

[0016] Plant mixture (BM) The plant mixture (BM) contained in the emulsion for hair cosmetics is b1) Bamboo extract b2) Cactus extract b3) Jojoba oil b4) Safflower oil b5) Olive oil b6) Babassu oil b7) Sesame seed oil b8) Rice bran oil b9) Evening primrose oil It contains nine types of plant-derived ingredients.

[0017] In one embodiment, the plant mixture (BM) contained in the hair cosmetic emulsion contains nine types of plant components: b1), b2), b3), b4), b5), b6), b7), b8), and b9).

[0018] The following provides a more detailed explanation of the nine plant components: b1), b2), b3), b4), b5), b6), b7), b8), and b9).

[0019] In preferred embodiments, the plant mixture (BM) is suitable for a wide range of users by providing diverse benefits tailored to various hair types. For dry and damaged hair, the oils and extracts deeply moisturize, repair split ends, and restore lost elasticity, making the hair softer and more manageable. For oily hair, it provides a light, non-greasy moisturizing effect and balances the scalp, helping to regulate sebum production without clogging pores. For curly or frizzy hair, the formula enhances moisture retention, reduces frizz, and accentuates curls, providing smoothness and manageability. For fine hair, its light ingredients provide necessary nourishment while preventing hair from drooping, resulting in a volumizing effect. Furthermore, for chemically treated or color-treated hair, antioxidants and repair compounds protect the hair from further damage, prevent color fading, and increase hair strength. This multifunctional approach ensures that the mixture meets diverse hair needs and improves overall health and appearance.

[0020] b1) Bamboo extract: Bamboo extract (component b1) is an extract derived from any part of the bamboo of the genus Bambusa. Component b1 is preferably extracted from the leaves, stems, and / or buds of the genus Bambusa, such as Bambusa vulgaris, to ensure a high concentration of physiologically active compounds. In addition to Bambusa vulgaris, other suitable species of the genus Bambusa include Bambusa oldhamii, Bambusa balcooa, Bambusa bambos, Bambusa tulda, Bambusa textilis, Bambusa multiplex, Bambusa arundinacea, Bambusa nutans, Bambusa blumeana, Bambusa tuldoides, Bambusa pervariabilis, and Bambusa emeiensis. These include Bambusa emeiensis, Bambusa lako, Bambusa dissimulator, Bambusa ventricose, and Bambusa beecheyana.

Amino acids (e.g., serine, glycine, proline) help repair and strengthen hair structure while promoting hydration and nourishment of the scalp. Phenolic acids and polyphenols exhibit anti-inflammatory and soothing effects, thereby supporting overall scalp health and reducing dandruff, making the extract suitable for sensitive or inflamed scalps.

[0023] b2) Cactus extract: Cactus extract (component b2) is an extract derived from any part of the cactus plant, such as the leaves, stems, flowers, and / or fruits, belonging to the Cactaceae family, a plant classification known for its moisturizing and protective properties. Suitable genera of the Cactaceae family include Opuntia, Cereus, Carnegia, Pachycereus, Stenocereus, Neobuxbaumia, Pilosocereus, Cephalocereus, Stephanocereus, Almatocereus, Remayleocereus, Ferocactus, Echinocactus, Thelocactus, Parodia, Echinopsis, Gymnocalycium, Mammillaria, Rebutia, Astrophytum, Lophophora, Cylindropuntia, Tephrocactus, Austrocylindropuntia, Maiphenia, Epiphyllum, Schlumbergera, Hatiora, Ariocarpus, Turbinicarpus, and Brosfeldia.

[0024] Suitable extractants include water, alcohol, and water-alcohol mixtures. The alcohol is preferably C 1-6Alcohol or a mixture of two or more of them, more preferably a linear C 1-6 alcohol, still more preferably C 1-4 alcohol, even more preferably a linear C 1-4 alcohol, even more preferably methanol, ethanol, n-propanol or isopropanol, and most preferably ethanol.

[0025] Component b2) is preferably extracted from the leaves, stems, flowers and / or fruits of Opuntia ficuin indica (Prickly Pair Cactus) or Cereus Grandiflorius, which are particularly rich in bioactive compounds. Component b2) is produced by an advanced water extraction, ethanol extraction or mixed solvent extraction process designed to maximize the preservation of its beneficial components. These beneficial components include the following. Polysaccharides (e.g., mucilage) achieve excellent moisture replenishment by forming a moisture-retaining barrier on both hair and scalp, and are particularly effective in dry or dehydrated conditions. Vitamins (e.g., vitamin E, vitamin C and vitamin B group) exert a strong antioxidant protective effect against free radicals and help prevent environmental damage and oxidative stress to hair and scalp. Minerals (e.g., calcium, magnesium, potassium) support the overall health of the scalp and contribute to strengthening hair roots, thereby reducing hair loss. Amino acids (e.g., proline, taurine) minimize brittleness by improving the moisturizing power of the scalp, repairing damage and enhancing the elasticity of hair bundles.

[0026] b3) Jojoba oil: Jojoba oil (component b3)) is obtained from the seeds of Simmondsia chinensis and is preferably in the form of a liquid wax ester.

[0027] Component b3) preferably mainly contains long-chain monounsaturated fatty acids (e.g., eicosenoic acid) and long-chain alcohols (e.g., docosanol, tetracosanol). Furthermore, it is preferable that it contains plant sterols that are rich in antioxidant tocopherol (vitamin E) and contribute to skin soothing and protection.

[0028] The production of component b3) (jojoba oil) preferably involves cold-pressing jojoba seeds and then filtering them to ensure purity.

[0031] The production of component b4) (safflower oil) preferably involves a cold-press or solvent extraction method.

[0032] Jojoba oil and safflower oil ideally work synergistically to ensure optimal hydration in hair and scalp care. Jojoba oil is a liquid wax ester derived from jojoba, very similar to the scalp's natural sebum, forming a light, non-greasy barrier layer that locks in moisture and prevents dryness. Its rich monounsaturated fatty acids and tocopherols smooth the hair cuticle while improving scalp health. Complementarily, safflower oil, derived from safflower, is high in linoleic acid, an omega-6 fatty acid, which penetrates the hair shaft to restore lipid balance and strengthen the structural integrity of the hair. Together, these oils form a dual-action system, in which jojoba oil seals and protects the outer layer of the hair, while safflower oil deeply nourishes and moisturizes the hair from within, resulting in soft, elastic, and well-hydrated hair. Jojoba oil and safflower oil, due to their combined effects, not only prevent moisture loss but also improve the overall health of the scalp, making them an ideal combination for maintaining moisture levels in various hair types.

[0050] Emulsion for hair cosmetics The emulsion for hair cosmetics according to the present invention is The aqueous phase (AP) that forms the continuous phase of the emulsion for hair cosmetics, It comprises an oil phase (OP) that forms the dispersed phase of a hair cosmetic emulsion.

[0051] In a preferred embodiment of the present invention, the emulsion for hair cosmetics contains 0.5 to 5% by weight, more preferably 0.5 to 2.0% by weight, and particularly preferably 0.5 to 1.6% by weight of a plant mixture (BM) based on the total weight of the emulsion for hair cosmetics.

[0052] In a preferred embodiment of the present invention, plant components b1) and b2) are contained in the aqueous phase (AP) of the hair cosmetic emulsion, and plant components b3), b4), b5), b6), b7), b8), and b9) are contained in the oil phase (OP) of the hair cosmetic emulsion.

[0053] Aqueous phase (AP) In a preferred embodiment of the present invention, the aqueous phase (AP) of the hair cosmetic emulsion comprises water and at least one cosmetically acceptable organic medium.

[0054] The term "at least one cosmetically acceptable organic medium" means exactly one cosmetically acceptable organic medium, and also means a mixture of two or more different cosmetically acceptable organic mediums.

[0055] In a preferred embodiment of the present invention, the aqueous phase (AP) of the hair cosmetic emulsion contains water in an amount of 70 to 90% by weight, based on the total weight of the aqueous phase (AP) contained in the hair cosmetic emulsion.

[0056] In another embodiment, the aqueous phase (AP) of the hair cosmetic emulsion contains 10 to 20% by weight of a cosmetically acceptable organic medium, based on the total weight of the aqueous phase (AP) contained in the hair cosmetic emulsion.

[0057] A cosmetically acceptable organic medium is preferably a water-miscible organic solvent, and preferably at least one alcohol.

[0058] In another embodiment, the cosmetically acceptable organic medium is at least one selected from the group consisting of monoalcohols such as ethanol and isopropanol, and polyalcohols such as propylene glycol, pentylene glycol, hexylene glycol, and glycerin.

[0059] In a preferred embodiment, the aqueous phase (AP) of the hair cosmetic emulsion contains, based on the total weight of the aqueous phase (AP) contained in the hair cosmetic emulsion, water in the range of 70 to 90% by weight and a mixture of pentylene glycol, propanediol, and glycerin in the range of 10 to 20% by weight.

[0060] The viscosity of the aqueous phase (AP) can be controlled by adjusting the amount of anionic polymer (especially carbomer) and the pH of the aqueous phase (AP). Generally, the pH of the aqueous phase (AP) is in the range of 5.5 to 6.5.

[0061] In a preferred embodiment, the pH value of the aqueous phase (AP) in the hair cosmetic emulsion of the present invention is in the range of 5.5 to 6.5.

[0062] In one embodiment, the aqueous phase (AP) has a viscosity of 400 mPas to 100,000 mPas, preferably 800 mPas to 30,000 mPas, measured at 25°C. This viscosity is measured by a method described later.

[0063] For the remainder of this specification, unless otherwise specified, temperature is assumed to be ambient temperature (e.g., T = 25°C ± 2°C) and pressure is assumed to be atmospheric pressure.

[0064] Viscosity is measured at room temperature (e.g., T=25°) under atmospheric pressure by the method described later.

[0065] A Brookfield-type viscometer, typically a Brookfield RVDV-E digital viscometer (with a spring torsional torque of 7187.0 dyn / cm), i.e., a rotational speed viscometer with a spindle, is used. By applying a rotational speed to the spindle and measuring the torque acting on it, the viscosity could be determined by understanding the geometric / shape parameters of the spindle being used. For example, a size No. 04 spindle (Brookfield, model number: RV4) is used. The shear rate corresponding to the viscosity measurement is defined by the spindle used and its rotational speed.

[0066] Viscosity measurement is performed at room temperature (T=25°C±2°C) for 1 minute. Approximately 150 g of the solution is placed in a beaker with a diameter of approximately 7 cm and a capacity of 250 ml, so that the height of its occupied volume reaches the level labeled on the spindle. The viscometer is then started at a speed of 10 rpm and waited until the value displayed on the screen stabilizes. As described in the context of this invention, this measurement provides the viscosity of the fluid under test.

[0067] As described above, the aqueous phase (AP) of the hair cosmetic emulsion of the present invention is preferably gel-like. Advantageously, the aqueous phase (AP) is not solid at room temperature (25°C) and atmospheric pressure, i.e., it is fluid due to its own gravity. In one embodiment, the aqueous phase (AP) has a viscosity of 400 mPa·s to 100,000 mPa·s, preferably 800 mPa·s to 30,000 mPa·s, measured at, for example, 25°C. This viscosity is measured by the method described above.

[0068] The aqueous phase (AP) of the hair cosmetic emulsion of the present invention may contain at least one base. The aqueous phase (AP) may contain a single base or a mixture of several different bases. The presence of at least one base in the aqueous phase (AP) particularly contributes to improving the viscosity of the aqueous phase (AP). In one embodiment, the base contained in the aqueous phase (AP) is an inorganic base. In one embodiment, the inorganic base is selected from the group formed by alkali metal hydroxides and alkaline earth metal hydroxides.

[0072] In a preferred embodiment, the aqueous phase (AP) of the hair cosmetic emulsion contains at least one anionic polymer.

[0073] The term "at least one anionic polymer" means exactly one anionic polymer, but it can also mean a mixture of two or more different anionic polymers.

[0074] Anionic polymers function as thickeners that increase the viscosity of the aqueous phase (AP).

[0075] In the present invention, "anionic polymer" means a polymer containing an anionic type chemical functional group. "Anionic type chemical functional group" means a functional group A that has lost a proton. - This refers to a chemically functional group AH capable of forming an AH. Therefore, depending on the state of the medium it contains, an anionic polymer can have an AH-type chemically functional group or a deprotonated base A. - It contains chemical functional groups of the type [type].

[0076] An example of anionic chemical functional groups is the carboxylate anion -COO - We can refer to the carboxylic acid functional group -COOH that may exist as such.

[0077] Examples of anionic polymers include any polymer formed by the polymerization of monomers having at least a portion of anionic chemical functional groups, such as carboxylic acid functional groups. For example, such monomers are acrylic acid, maleic acid, or any ethylenically unsaturated monomer containing at least one carboxylic acid functional group.

[0080] In a preferred embodiment of the present invention, the anionic polymer is at least one carbomer as described below. The carbomer is a crosslinked acrylate / C 10-30 Alkyl acrylate copolymer (INCI name: acrylate / C) 10-30 It may also be an alkyl acrylate crosspolymer.

[0081] In the present invention, unless otherwise specified, "carbomer" means an optionally crosslinked homopolymer obtained by polymerization of acrylic acid. Therefore, it is optionally crosslinked poly(acrylic acid). Among the carbomers of the present invention, we may refer to those commercially available under the trade names Tego® Carbomer 340FD manufactured by Evonik, Carbopol® 981 manufactured by Lubrizol, Carbopol ETD 2050 manufactured by Lubrizol, or Carbopol Ultrez 10 manufactured by Lubrizol.

[0082] In one embodiment, "carbomer" or "Carbopol®" means a high molecular weight acrylic acid polymer crosslinked with allyl ether of allyl sucrose or pentaerythritol (Handbook of Pharmaceutical Additives, 5th Edition, Tablets). For example, it is Carbopol® 910, Carbopol® 934, Carbopol® 934P, Carbopol® 940, Carbopol® 941, Carbopol® 71 G, Carbopol® 980, Carbopol® 971P, or Carbopol® 974P. In one embodiment, the viscosity of the above carbomer is 4,000 to 60,000 cP at 0.5% w / w.

[0083] Carbomer is also known by other names such as polyacrylic acid, carboxyvinyl polymer, or carboxypolyethylene.

[0084] The aqueous phase (AP) according to the present invention may contain 0.01 to 5% by weight, preferably 0.05 to 2% by weight, and more preferably 0.1 to 0.5% by weight of an anionic polymer, particularly a carbomer, relative to the total aqueous phase (AP).

[0085] The aqueous phase (AP) according to the present invention comprises carbomer and acrylate / C 10-30 It may also contain alkyl acrylate crosspolymer.

[0086] The aqueous phase (AP) of the present invention may contain at least one crosslinked polymer or at least one crosslinked copolymer, wherein the crosslinked polymer or crosslinked copolymer contains at least one unit obtained by polymerization of one monomer from among acrylic acid or methacrylic acid, alkyl acrylate or methacrylate having 1 to 30 carbon atoms, or salts thereof.

[0087] In a preferred embodiment, the aqueous phase (AP) of the hair cosmetic emulsion contains at least one polyvinylpyrrolidone thickener in an amount ranging from 0.1 to 1.5% by weight, based on the total weight of the aqueous phase (AP) contained in the hair cosmetic emulsion. K-90 type polyvinylpyrrolidone is preferred.

[0088] Oil phase (OP) In a preferred embodiment of the present invention, the oil phase (OP) contained in the emulsion for hair cosmetics is in droplet form.

[0089] The droplets of the emulsion for hair cosmetics of the present invention are preferably macroscopic droplets, that is, droplets that are visible to the naked eye, in contrast to microscopic droplets that are invisible to the naked eye.

[0090] Therefore, in one embodiment, at least 60%, more preferably at least 70%, more preferably at least 80%, more preferably at least 90% of the droplets have an average diameter D of 100 μm or more, more preferably 200 μm or more, more preferably 300 μm or more, and particularly 400 μm or more.

[0091] In a preferred embodiment, the average diameter D of the droplet is in the range of 100 μm to 3000 μm, more preferably in the range of 200 μm to 2000 μm, particularly in the range of 300 μm to 1700 μm, even more preferably in the range of 400 μm to 1600 μm, most preferably in the range of 450 μm to 1550 μm, and most preferably in the range of 500 μm to 1500 μm.

[0092] Advantageously, in the emulsion for hair cosmetics according to the present invention, droplets having a diameter in the range of 100 μm to 3000 μm, more preferably 200 μm to 2000 μm, particularly 300 μm to 1700 μm, even more preferably 400 μm to 1650 μm, most preferably 450 μm to 1550 μm, and most preferably 500 μm to 1500 μm, account for 60% or more, more preferably 70% or more, more preferably 80% or more, and more preferably 90% or more of the total volume of the oil phase (OP).

[0093] Determining the volume of droplets with the aforementioned specific diameter relative to the total volume of the oil phase (OP) depends on the general knowledge of those skilled in the art.

These examples are not intended to include all aspects of the subject matter disclosed herein, but rather to show representative compositions and results. These examples are not intended to exclude equivalents and variations of the present invention that would be obvious to those skilled in the art.

[0167] The following hair cosmetic emulsions were tested.

[0168] HT1 is an emulsion for hair cosmetics according to the present invention. The components contained in this hair cosmetic emulsion HT1 are shown in Table 1 below.

[0169] Table 1 TIFF2026113416000002.tif252170TIFF2026113416000003.tif56170

[0170] All tests will be conducted using natural white blonde hair strands provided by International Hair Importers & Products (Glendale, New York). Each strand weighs approximately 3 grams and measures 8 inches in length and 1 inch in width. Ten strands will be used for each treatment group.

[0171] All processes are performed using an Intellifaucet set to 40°C and controlled at a flow rate of 1 GPM. Before the experiment, all hair bundles are standardized with a 15% sodium laureth sulfate (SLES) solution.

[0172] Processing group (TG0): TG0 is the water control group and does not use hair cosmetic emulsion. Perform one cycle.

[0173] Processing group (TG1): In TG1, the hair cosmetic emulsion HT1 (according to the present invention) is used. Apply 10% of the hair bundle weight (0.1g per gram of hair) of the hair cosmetic emulsion to dry hair, massage for 30 seconds (to ensure that the droplets dissolve), and leave the hair cosmetic emulsion on without rinsing it off. Repeat one cycle.

[0174] application: 1. Perform baseline measurements on clean, untreated hair. 2. Treat the hair bundles with the test product as described above, and dry them to reach equilibrium. 3. Expose the hair strands to contamination as shown below. 4. Conduct measurements after contamination. 5. Treat the hair again with 15% SLES solution and dry it to reach equilibrium. 6. Perform measurements after washing.

[0175] Exposure to particulate contamination The test chamber (see attached Figure 1) is fundamental to this protocol. Four hair strands are exposed at a time. 1. Turn on the power using the power control unit. Remove the glass tube connecting the premixing chamber and the main chamber. Open the lid of the main chamber. Brush the four bundles of hair clean and hang them on the rack inside the main chamber (every other clip). Close the lid. Position the glass tube to connect the premixing chamber and the main chamber. Open the compressed air valve and use the flow of compressed air to dry the chamber for 5 minutes. Reduce the gas flow to a minimum and close the compressed air valve. 2. Weigh 25 mg of graphite particles (particle size approximately 1 μm) and place them in the premixing chamber. Crush any large particle clumps using a magnetic stirrer. 3. Start rotating the hair bundle using the hair bundle rotation control panel. The rotation direction (clockwise / counterclockwise) can be controlled by the knob. Reverse the rotation direction every 2 minutes throughout the exposure period to ensure that the particles are more evenly dispersed on the surface of the hair. 4. Open the compressed air valve and slowly allow the gas to flow so that particles are gradually introduced into the main chamber (no particles should remain in the premixed chamber during the first 10 minutes). The compressed air should maintain the relative humidity in the main chamber below 10%. After 18 minutes, reduce the compressed air flow to a minimum and turn off the valve and magnetic stirrer. Operate the humidifier at maximum capacity to raise the humidity in the chamber to approximately 50%. After 2 minutes (20 minutes total), stop the rotation of the bristle bundle and allow it to stand in the chamber for 5 minutes to reduce environmental contamination after opening the lid. 5. Before measuring, take a strand of hair and brush it 10 times to detangle it (use a different brush depending on the treatment).

[0176] An evaluation will be conducted after one cycle.

[0177] Label each hair strand. Characterize the hair color by measuring baseline L, a, and b using a WF30 portable colorimeter.

[0178] Technical hair color is quantified using the CIELAB L, a, and b systems. The color is represented in a three-dimensional matrix, where "L" represents lightness in the range of 0 to 100, "a" represents the red-green color gamut (positive values ​​indicate a stronger red tint), and "b" represents the yellow-blue color gamut (positive values ​​indicate a stronger yellow tint).

[0179] After one contamination cycle, a statistical difference in brightness (ΔL) was observed between treatment group TG0 (water control) and treatment group TG1. The values ​​of brightness (ΔL) are shown in Table 2 below.

[0180] Table 2 (ΔL after contamination): TIFF2026113416000004.tif21170

[0181] After washing, a statistical difference in brightness (ΔL) was observed between treatment group TG0 (water control) and treatment group TG1. The values ​​of brightness (ΔL) are shown in Table 3 below.

[0182] Table 3 (ΔL after washing): TIFF2026113416000005.tif21170

[0183] The results after washing shown in Table 3 demonstrate a statistically small change in brightness, indicating that the emulsion for hair cosmetics of the present invention can more easily remove particulate contamination from the surface of the hair through washing.
