Description

[Technical field]

[0001] The present invention relates to a cosmetic product for bleaching or dyeing hair. [Background technology]

[0002] In recent years, hair bleaching agents and hair dyeing agents have been proposed that can be discharged in the form of foam to simplify the bleaching or dyeing operation, and for example, one-component or two-component aerosol or non-aerosol types are known. However, when a typical foam preparation is applied to hair that has sebum, leave-in-bath hair treatments, hair conditioners, etc. attached thereto, the foam tends to disappear when the discharged foam is applied to the hair or held on the hair, and dripping may occur, which causes a problem that the hair cannot be dyed evenly and neatly.

[0003] To solve this problem, a non-aerosol type hair bleaching or dyeing cosmetic product is known that contains a specific anionic surfactant and a specific cationic polymer in a mixture of the first and second agents, which results in good foaming and foam retention, and enables bleaching or dyeing without uneven color, even when applied to hair that has been coated with the hair cosmetic (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-107962 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, even with the technology described in Patent Document 1, there was a problem that the agent did not easily penetrate to the inside of the hair (near the roots) depending on the foam application method used by the practitioner. That is, practitioners who are not very skilled in bleaching or coloring, for example, ordinary people who have just started using hair color at home, tend to "smooth" the discharged foam onto the hair, and in such cases, the foam does not penetrate sufficiently to the inside of the hair, which is likely to result in undyed or uneven dyeing. In addition, for people who are not satisfied with the finish and want a better finish, excellent penetration to the inside of the hair is a desirable characteristic of a foam hair bleach or hair dye.

[0006] Therefore, the present invention relates to a foam-type cosmetic product for bleaching or dyeing hair that makes use of the technical advantages described in Patent Document 1 and allows the agent to fully penetrate to the inside of the hair (up to the roots), resulting in a finish with no uneven color on the surface or inside of the hair. [Means for solving the problem]

[0007] The present inventors have found that in a multi-component hair bleaching or dyeing cosmetic product in which a mixed solution containing a first agent containing an alkaline agent and a second agent containing hydrogen peroxide is discharged in the form of foam from a container, an ionic surfactant having an anionic group, a nonionic surfactant, and a specific cationic polymer are used in combination, and the relative amount of the nonionic surfactant to the ionic surfactant in the mixed solution is reduced, thereby significantly improving the permeability of the discharged foam to the inside of the hair (up to the vicinity of the root) and the migration of the mixed solution components into the inside of the hair fibers, and further improving the stability of the foam against oily components such as sebum. As a result, the present invention exhibits high bleaching or dyeing properties without color unevenness between the inside and surface of the hair. This is presumably because the coacervate complex formed by the ionic surfactant and the cationic polymer has a low water content and a small size, and the coacervate complex is distributed near the gas-liquid interface in the liquid film of the discharged foam.

[0008] The present invention provides a cosmetic product for hair bleaching or hair dyeing, comprising a first agent containing an alkaline agent, a second agent containing hydrogen peroxide, and a container for discharging a mixed liquid containing the first agent and the second agent in the form of foam, The mixture contains the following components (A) to (C), and the mass ratio (B) / (A) of component (B) to component (A) in the mixture is greater than 0 and not greater than 0.44. The present invention provides a cosmetic product for bleaching or dyeing hair. (A) Ionic surfactant having an anionic group (B) Nonionic surfactants (C) Polymer containing diallyl quaternary ammonium salt as a structural unit

[0009] The present invention further provides a hair bleaching or dyeing method using the above-mentioned hair bleaching or dyeing cosmetic product, ejecting a mixed liquid containing the first and second agents from a container in the form of foam, and applying the foam to the hair by hand.

[0077] [Oil] The cosmetic product for hair bleaching or hair dyeing of the present invention may further contain an oil in the mixed liquid from the viewpoint of stabilizing the foam of the mixed liquid to be discharged. Examples of such oils include hydrocarbons such as squalene, squalane, liquid paraffin, liquid isoparaffin, and cycloparaffin; glycerides such as castor oil, cocoa oil, mink oil, avocado oil, and olive oil; waxes such as beeswax, spermaceti, lanolin, and carnauba wax; esters such as isopropyl palmitate, isopropyl myristate, octyldodecyl myristate, hexyl laurate, cetyl lactate, propylene glycol monostearate, oleyl oleate, hexadecyl 2-ethylhexanoate, isononyl isononanoate, and tridecyl isononanoate; higher fatty acids such as capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, coconut oil fatty acid, isostearyl acid, and isopalmitic acid; and others such as isostearyl glyceryl ether and polyoxypropylene butyl ether.

[0079] [Silicones] In the cosmetic product for hair bleaching or dyeing of the present invention, it is preferable that the mixed solution does not contain silicone from the viewpoint of maintaining the discharged foam for a long time, but in order to make the foam blend smoothly with the hair and to impart a high conditioning effect to the hair, silicones can also be contained within a certain range. Examples of silicones include dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified silicone, amino-modified silicone, oxazoline-modified silicone elastomer, etc., and emulsions of these dispersed in water with a surfactant. Among these, polyether-modified silicone, amino-modified silicone, and emulsions thereof are preferred from the viewpoint of being stably dispersible in water without using a thickener.

[0080] Polyether-modified silicones include those that are terminally modified and side-chain modified, such as pendant type (comb type), both terminally modified type, and one terminal modified type. Examples of such modified silicones include dimethylsiloxane-methyl(polyoxyethylene)siloxane copolymer, dimethylsiloxane-methyl(polyoxypropylene)siloxane copolymer, and dimethylsiloxane-methyl(polyoxyethylene-polyoxypropylene)siloxane copolymer. As polyether-modified silicones, those with HLB of 10 or more, and further HLB of 10 to 18 are preferred from the viewpoint of compatibility with water. Here, HLB is a value calculated from the cloud number (cloud number: an index correlated with HLB and applied to ether-type nonionic surfactants).

[0081] The amino-modified silicone may be any silicone having an amino group or an ammonium group, with amodimethicone being preferred.

[0082] When silicones are added to the mixed liquid, the content of the silicones is preferably 0.005% by mass or more, and more preferably 0.01% by mass or more, from the viewpoint of allowing the foam to blend smoothly with the hair and imparting a high conditioning effect to the hair, and is preferably 2% by mass or less, further preferably 1.5% by mass or less, and even 1% by mass or less, from the viewpoint of not interfering with the foaming of the discharged mixed liquid.

[0083] [Non-volatile hydrophilic solvent] Furthermore, it is preferable that the mixed solution contains a non-volatile hydrophilic solvent. This can reduce irritation to the scalp caused by the evaporation of water from the mixed solution and the concentration of irritating components such as hydrogen peroxide while the foam of the mixed solution is applied to the hair and left to stand. As the non-volatile hydrophilic solvent, polyols and their lower (1 to 4 carbon atoms) alkyl ethers are preferable. As the polyols, those having 2 to 6 carbon atoms are preferable, and examples thereof include glycerin, diglycerin, propylene glycol, dipropylene glycol, 1,3-butanediol, ethylene glycol, diethylene glycol, isoprene glycol, and sorbitol. As the lower alkyl ethers of polyols, mono-lower alkyl ethers and poly-lower alkyl ethers (e.g., di-lower alkyl ethers) of polyols are preferable. Among them, monomethyl ethers or monoethyl ethers of polyols are preferable, and specifically, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, and the like can be mentioned. These can be used in combination of two or more kinds.

[0084] The content of the non-volatile hydrophilic solvent in the mixed solution is preferably 0.1% by mass or more, more preferably 0.3% by mass or more, even more preferably 0.5% by mass or more, and even more preferably 1% by mass or more, from the viewpoint of the effect of reducing scalp irritation and the effect of improving foam quality, and is preferably 10% by mass or less, more preferably 5% by mass or less, even more preferably 4% by mass or less, and even more preferably 3% by mass or less.

[0085] [Other optional ingredients] In addition to the above-mentioned components, other components usually used as cosmetic raw materials can be added to the hair bleaching or dyeing cosmetic of the present invention. Such optional components include animal and vegetable oils and fats, natural or synthetic polymers, ethers, protein derivatives, hydrolyzed proteins, amino acids, preservatives, chelating agents, stabilizers, antioxidants, plant extracts, herbal extracts, vitamins, fragrances, ultraviolet absorbers, etc.

[0086] [pH] The pH (25° C.) of the mixed solution of the hair bleaching or hair dyeing cosmetic product of the present invention is, from the viewpoints of bleaching or dyeing effect and skin irritation, preferably 8 or more, more preferably 9 or more, and is preferably 12 or less, more preferably 11 or less, and even more preferably 10.5 or less. Examples of pH adjusters include, in addition to the above-mentioned alkaline agents, inorganic acids such as hydrochloric acid and phosphoric acid; organic acids such as citric acid, glycolic acid, and lactic acid; and phosphates such as monopotassium dihydrogen phosphate and disodium monohydrogen phosphate.

[0087] 〔viscosity〕 The preferred viscosity range of the mixture is preferably 1 mPa·s or more, more preferably 5 mPa·s or more, and also preferably 600 mPa·s or less, more preferably 300 mPa·s or less, even more preferably 200 mPa·s or less, and even more preferably 100 mPa·s or less. The viscosity here is measured at 25°C using a B-type rotational viscometer (model: digital viscometer TV-10, Toki Sangyo Co., Ltd.) with rotor No. 1, with a rotation speed of 60 rpm when the measurement target is 100 mPa·s or less, 30 rpm when it is 100 to 200 mPa·s, and 12 rpm when it is 200 mPa·s or more. Measurements are performed in order from the highest rotation speed, and the measurement is completed when the measurement can be completed without the display going off the scale, and measurements with lower rotation speeds thereafter are not performed. The viscosity of the mixture is measured 3 minutes after the start of mixing each agent.

[0088] By adjusting the viscosity of the mixture to the above range, it is possible to realize a foam volume that is easy to apply, and to suppress dripping of the mixture after application to hair. In addition, it becomes easier to squeeze the foam when it is discharged by a squeeze foamer, and easier to pump the foam when it is discharged by a pump foamer. In order to adjust the viscosity of the mixture to the above range, a water-soluble solvent may be added, or the content or type of surfactant, polyol, higher alcohol, etc. may be appropriately adjusted.

[0089] 〔container〕 In the present invention, the container for discharging the mixture containing the first and second agents in the form of foam is preferably a non-aerosol type foamer container, which is used to mix the mixture containing the first and second agents with air and discharge it in the form of foam without using a propellant. The use of a foamer container has the effect of preventing the agent from scattering when discharged, and also has the effect of discharging a foam in which the first and second agents are uniformly mixed. In particular, non-aerosol type containers allow the product to be manufactured more cheaply than aerosol type containers, and since a high-pressure gas propellant is not required, the product can be handled more safely during distribution.

[0090] As the foamer container, a known pump foamer container, a squeeze foamer container, an electric whisk, a pressure-accumulating pump foamer container, etc. having a foam discharge means can be used. More specifically, for example, pump foamer type E3 and type F2 (both manufactured by Yamato Can Co., Ltd.) described in Food and Containers (vol. 35, No. 10, p. 588-593 (1994); vol. 35, No. 11, p. 624-627 (1994); vol. 36, No. 3, p. 154-158 (1995)) can be mentioned, as well as a squeeze foamer (manufactured by Yamato Can Co., Ltd.), an electric whisk (manufactured by Panasonic Corporation), and an air spray foamer (manufactured by Air Spray International Co., Ltd.). As the foamer container used for the hair bleaching or dyeing cosmetic product of the present invention, a pump foamer container and a squeeze foamer container are preferred because they are inexpensive and easy to use.

[0091] The pump foamer container or squeeze foamer container has a foam generating part such as a net, and preferably has a thin net because when the mixture of the first and second agents dries and solidifies, clogging occurs, the solidified matter can be dissolved immediately by the flow of foam at the next discharge to eliminate clogging. In this case, the mesh of the net is preferably 50 to 350 mesh, more preferably 70 to 280 mesh, more preferably 90 to 250 mesh, and even more preferably 130 to 220 mesh. Here, mesh refers to the number of holes per inch. By using a net with a mesh in this range, creamy foam can be generated. In addition, nylon, polyester, etc. can be preferably exemplified as the material of such a mesh.

[0092] The foamer container used in the hair bleaching or hair dyeing cosmetic product of the present invention is provided with at least one such net, and preferably multiple nets, and it is particularly preferable to provide two nets from the standpoints of economy, foam stability, etc.

[0093] In the foamer container, the parts that come into contact with the contents (the inner wall of the container, the inner wall of the foam discharging means, etc.) are preferably made of a material that is not corroded by alkali and hydrogen peroxide and that is permeable to oxygen generated by decomposition of hydrogen peroxide.

[0094] As for the product form of the hair bleaching or hair dyeing cosmetic product of the present invention having the first agent, the second agent, and the former container, the first agent and the second agent may be filled in a container separate from the former container, and both agents may be transferred to the former container and mixed when used, or one agent may be filled in the former container and the other agent may be filled in a separate container, and the other agent may be transferred into the former container when used. In this case, the second agent is preferably filled in a gas-permeable container, particularly a former container made of an oxygen-permeable material (e.g., polyethylene), in order to prevent the pressure inside the container from increasing due to oxygen generated by the decomposition of hydrogen peroxide. On the other hand, it is necessary to use a container that is difficult for oxygen to pass through for the first agent in order to prevent the oxidation of the oxidation dye.

[0095] The mixing ratio of the first agent to the second agent in the hair bleaching or dyeing cosmetic product of the present invention is preferably 1:4 to 4:1 by mass, and more preferably 1:3 to 1:1.

[0096] [Gas-liquid mixture ratio] The gas-liquid mixture ratio of air and the mixed liquid by the foam discharge means of the foamer container is preferably 5 to 40 mL / g, more preferably 6 to 30 mL / g, from the viewpoint of the agent's compatibility with hair and ease of application. The gas-liquid mixture ratio here is a value measured as follows.

[0097] First, the gas-liquid mixture ratio is determined by measuring the mass and volume of the foam discharged at 25°C. 100g of the mixture is placed in a squeeze foamer container (Yamato Can Co., Ltd., volume 210mL, mesh coarseness (openings) 150 mesh in the mixing chamber (150 squares per inch (25.4mm)), 200 mesh at the tip), and when 80g remains, 20g of foam is discharged into a 1000mL measuring cylinder, and the foam volume is measured 1 minute after the start of discharge. The gas-liquid mixture ratio (mL / g) is obtained by dividing the volume (mL) of the discharged foam by the mass of 20g.

[0098] [How to use] In bleaching or dyeing hair using the hair bleaching or dyeing cosmetic of the present invention, it is preferable to comb the hair in advance. This makes it difficult for the hair to become tangled during the re-foaming process described below, so there is no risk of the mixed liquid scattering. In addition, after combing the hair, it is not necessary to perform a blocking operation that is commonly used in the application of a bleaching or dyeing composition, and it is even preferable not to perform a blocking operation. This makes it easier to apply the bleaching or dyeing composition to hair and to re-foam the composition described below. In addition, this re-foaming operation makes it possible to obtain a finish with even color unevenness even when the hair bleaching or dyeing cosmetic of the present invention is applied to hair that still has a hair styling product on it. Next, the first and second agents of the hair bleaching or dyeing cosmetic of the present invention are mixed in a foamer container. The foam agent discharged from the container may be applied directly to the hair, or may be applied to the hair using a tool such as a hand or a brush. In order to prevent the agent from splashing or dripping, it is more preferable to apply the agent to the hair after first taking the agent in the hands (wearing gloves).

[0099] After application, the mixture is left for about 3 to 60 minutes, preferably about 5 to 45 minutes. In this case, it is preferable to lather the mixture again on the hair in order to further prevent dripping during the time of leaving the mixture and to ensure that the mixture reaches the roots of the hair. To lather the mixture again, gas may be injected, a tool such as a vibrator or a brush may be used, or fingers may be used, but it is more preferable to rub the mixture with fingers.

[0100] The timing of re-whisking may be after the foam has completely disappeared, while the foam is disappearing, or before the applied foam changes. Alternatively, the foam may be applied to the entire area to be applied, or during application. Re-whisking may be performed continuously once, or may be repeated intermittently multiple times.

[0101] After these procedures, the mixture is washed off, and then the hair is appropriately shampooed and rinsed, washed with water, and dried.

[0102] With respect to the above-described embodiment, preferred aspects of the present invention will be further disclosed below.

EXAMPLES

[0134] Example 1, Comparative Example 1 The first agent (solubilization solution) and the second agent (emulsion solution) were prepared according to the formulation shown in Table 1, and mixed at a mass ratio of 1:1.5 to prepare a mixed solution. This mixed solution was then passed through a squeeze former (Yamato Can Co., Ltd., volume 210 mL, mesh coarseness: mixing chamber 150 mesh, tip 200 mesh, total opening area of ​​the narrowest part of the air introduction passage was 0.35 mm 2 The solution was discharged in foam form using a dip tube with an inner diameter of φ1.75 mm, and the following evaluations were carried out.

[0135] 1. Foam permeability evaluation (Evaluation method) A specialist panelist dispensed one push (approximately 3 g) of foam from the squeeze foamer container onto the palm of the hand, and applied the foam three times over a distance of approximately 20 cm from the top of the head of a mannequin with medium-length hair, applying a force of approximately 600 g. This action was repeated twice. The inside of the head, approximately 5 cm from the top, was sliced ​​(the hair was split and the inside was opened) with the pointed handle of a general ring comb (tail comb), and the penetration of the foam was visually confirmed and evaluated according to the following criteria. The results are shown in Table 2.

[0136] (Evaluation Criteria) A: The coating is evenly applied to the inside. B: Although it is not uniform, the foam is partially applied to about half of the surface. C: The foam is applied unevenly in places. D: No foam has penetrated at all

[0137] 2. Evaluation of sebum resistance (Evaluation method) Approximately 0.8 g of glyceryl tricaprylate as simulated sebum and 0.6 g of Kao Corporation's "Liese Playful Care Oil" as a general hair oil were applied to the entire scalp of a mannequin with medium-length hair. A specialist panelist dispensed foam from the squeeze foamer container and applied the foam to a mannequin while creating a parting, applying a total of 80g (a mixture of 32g of the first agent and 48g of the second agent) and then kneading for 2-4 seconds. The mannequin was then left to stand at room temperature for 20 minutes, sliced, and the remaining foam was checked and evaluated according to the following criteria. The results are shown in Table 2.

[0138] (Evaluation Criteria) A: There is a uniform amount of foam inside. B: The foam disappears, but the foam remains unevenly. C: Almost all of the bubbles have disappeared and no bubbles remain. D: No bubbles remain / Drips occur
