Description

The present invention relates to a hair coloring agent composition, and more particularly to a hair coloring agent composition capable of reducing skin disorders.

Hair coloring mainly includes hair coloring, which is a permanent hair dye for quasi-drugs, and hair manicure and hair color treatment, which are semi-permanent hair dyes for cosmetics. In particular, the hair color of permanent hair dyes mainly contains a substance called para-phenylenediamine (oxidation dye), but in the case of dark black colors, the amount of diamine compounds is large, so further Attention is needed.

For example, as a hair coloring composition containing para-phenylenediamine (oxidative dye), it was selected from (a) water-soluble peroxygen bleach; (b) organic peroxyic acid bleach precursor and / or preformed organic peroxy acid. A hair coloring composition characterized by containing a bleaching aid; and (c) one or more hair coloring agents is known (Patent Document 1).

Special table 11-501947

However, in the prior art including the above Patent Document 1, those containing para-phenylenediamine (oxidation dye) are further noted because the amount of the diamine-based compound is large in the case of a dark black color as described above. In recent years, skin disorders have been reported due to a substance called para-phenylenediamine (oxidative dye).

In addition, hair manicure, which is a semi-permanent hair dye, is characterized by the fact that the pigment (acid dye) penetrates into the inside of the hair and retains color for 2 to 3 weeks with a single use, but it will be longer if it adheres to the scalp and is left for a long time. It is difficult to remove the dyed pigment, it is difficult for the practitioner to apply it to the very limit of the hairline, and the dyeing is worse than the hair color for the practitioner's skill, so hair dyes that are often avoided in salons and beauty salons. It has become.

Also, in recent years, for healthy hair, there has been a demand for "design color" and "fashionable dyeing" for hair with increased color tone, and the brightness is partially changed to give a three-dimensional effect, or a part is dyed. It is desired to make points.

Therefore, an object of the present invention is to provide a hair coloring agent that is para-phenylenediamine-free, can reduce skin disorders, and can be designed.

Further, in a preferred embodiment of the post-bleaching hair coloring agent composition of the present invention, the tertiary amine is characterized by being dimethylaminopropyl amide stearate, diethyl aminoethyl amide stearate, or behenamide propyl dimethylamine. And.

Further, the post-bleaching hair coloring agent of the present invention is characterized by containing the post-bleaching hair coloring agent composition of the present invention.

According to the post-bleaching hair coloring composition of the present invention, it does not contain para-phenylenediamine and is suitable for those who are suffering from scalp or who are worried about contact dermatitis, and the use of hair coloring due to aging. Since it has the potential to extend the period, it is possible to provide a hair color product that can be used with confidence and has a long-lasting color, and that the practitioner can apply it to the new part without worrying about adhesion to the scalp. It has an advantageous effect.

Further, according to the post-bleaching hair coloring agent composition of the present invention, the use of a specific component has good permeability, and it is possible to realize a design color or the like even with a small amount of a dyeing agent or the like. It has the advantageous effect of being.

FIG. 1 is a diagram showing the observation results of a hair cross-section sample treated in a 0%, 1%, and 3% solution of 3-mercapto-1,2-propanediol when various dyes were used with an optical microscope. ..

The post-bleaching hair coloring composition of the present invention comprises at least one selected from the group consisting of thioglycolic acid, cysteine, 3-mercapto-1,2-propanediol, cysteamine, and derivatives and salts thereof, and hydroxy. A hair coloring composition containing sodium methanesulfinate, a basic dye, an HC dye, an amino acid, a cationic surfactant, a thickener, an oil agent, a pH adjuster, and a wetting agent. The hair coloring agent composition has a pH of 3.5 or more. This can be done by blending thioglycerin (scientific name: 3-mercapto-1,2-propanediol) and / or sodium hydroxymethanesulfinate, etc. without raising the pH or heating. This is because the present inventors have found that the hair dyeing is better than the hair dyeing by raising the pH and heating the hair without blending the above. Further, in the post-bleaching hair coloring composition of the present invention, it was found that the cuticle can be easily opened by setting the pH to 6.8 or higher, and at the same time, L-arginine, L-lysine, L-histidine, and the like thereof. It was found that it is a product that can perform color treatment while sending basic amino acids such as salts into the hair to supplement and repair the basic amino acids that have flowed out due to pain. That is, in hair color treatments and the like, cuticles (hair follicles) and cortex near the surface of the hair are dyed, and in some cases it is not possible to achieve a hair color having a sufficiently long-lasting color. By applying the colorant composition, it is possible to open the cuticle, which in turn has the advantageous effect of achieving a hair color with good color retention.

Here, it is clearly stated that what is used after decolorization is the treatment after the so-called decolorization step. That is, hair color is directly applied to healthy hair by using thioglycolic acid, cysteine, 3-mercapto-1,2-propanediol, cysteamine, etc., which have the above-mentioned hair penetrating effect, unless the hair has been decolorized once. This is because even if the agent composition is applied, almost no change is observed in the black hair, and as a result, the design color may not be enjoyed. Therefore, the present invention can be more effectively exerted on the hair that has been once decolorized.

In the present invention, the decolorization treatment is not particularly limited by a conventional method.

Further, in a preferred embodiment of the present invention, from the viewpoint of design color, the blending amount of the basic dye or the HC dye is 0.5% by mass or less with respect to the total amount of the composition. Further, from the viewpoint of design color, the total amount of the composition is preferably 0.005 to 0.5% by mass, more preferably 0.01 to 0.45% by mass, and further preferably 0. It can be 05 to 0.4% by mass. If the blending amount of the basic dye or the HC dye is more than 0.5% by mass, the brightness may decrease, and it may be difficult to achieve the desired effect. In gray hair dyeing, gray hair was dyed deeply and settled to a brightness of about 4 to 5 on a scale level. In addition, the brightness of 6 to 7 levels looks like black hair on the ground hair of healthy hair or under lighting, but the hair color looks a little brown when exposed to the sun, and the atmosphere is softer than the black hair color. It is said that it can be seen, and it is said that the judgment criteria are bright in the workplaces of banks, hotels, Japanese airlines, etc. The level called fashionable dyeing of the present invention aims at 8 to 10 levels in which the brightness is further increased, and the brightness of 11 levels or more is in the oxidative hair dye range as a permanent hair dye. Therefore, in the examples described later, a hair coloring level scale sold by the Japan Hair Color Association (JHCA) is purchased, and hair is used with a spectrocolorimeter (manufactured by Nippon Denshoku Kogyo Co., Ltd., model number: SD 6000). The brightness of the bundle was measured and quantified. In addition, when two colors of blue and red scarlet were dyed on each decolorized hair bundle and measured using a spectrocolorimeter, the scarlet dye content was 0.8% and the measured value of brightness (L *) was 0.8%. At 19.79, the amount of blue dye was 0.8% and the measured brightness (L *) was 19.12, which was found to correspond to 9 levels. From this point of view, the desired amount can be finally determined for the desired brightness.

Conventionally, gray hair dyeing has been carried out exclusively by thickening the dye with a composition containing 1 to 3% by mass of a basic dye. That is, there is no black color in the basic dye, and the brown color is darkened or the blue color is darkened to make it blackish. As a result of investigating whether basic dyes can be applied to healthy hair this time, by adding sodium hydroxymethanesulfinate and thioglycerin (3-mercapto 1,2-propanediol), more pigment is added to the inside of the hair. Allows for a deeper blackish finish, surprisingly even less than 0.5% by weight of the existing dye amount reduced by 30-50 times. The present inventors have found that the design color and the like can be enjoyed by undergoing the decolorization step.

For example, since the amount of compounded pigment is reduced, only the gray hair part is dyed for those who have 10% or more of gray hair, resulting in uneven dyeing. The present invention can be preferably used for healthy hair, and a decontamination agent (lightener or powder bleaching agent) is used for healthy hair, for example, a hair coloring level scale sold by the Japan Hair Color Association. It can have the effect of enjoying "design color" and "fashionable dyeing", which makes the hair with the color tone raised to 9 to 11 levels.

Further, in the present invention, at least one selected from the group consisting of thioglycolic acid, cystine, 3-mercapto-1,2-propanediol, cysteamine, and derivatives and salts thereof, and / or sodium hydroxymethanesulfinate. By including these components, it is possible to allow components such as dyes to penetrate deeply into the hair, and even a small amount of dye can sufficiently realize hair color, and it can be contained for a long period of time. This is because it is possible to maintain the effect of the dye throughout.

Examples of the antibody production inhibitor include pomegranate seed extract, mushrooms belonging to the genus Agaricus, and extracts such as Yanagihakka and Edelweiss from the viewpoint of prevention and improvement of allergic diseases.

For example, the case where a pomegranate seed extract is used as an antibody production inhibitor will be described as an example. Pomegranate seed extract is an extract derived from pomegranate seeds. The pomegranate seed extract applied to the present invention covers all pomegranate seed extracts as long as they are derived from pomegranate seeds.

Further, in a preferred embodiment, the pomegranate seed extract is characterized by containing punic acid or ellagic acid. The pomegranate seed extract can be obtained, for example, by the following method. First, the pulverized product obtained by crushing pomegranate seeds is immersed in at least one solvent selected from the group consisting of ethanol, methanol, water and hexane, and the supernatant is separated to obtain the pomegranate seed extract. It is characterized by the fact that it was obtained. For example, it can be shaken and extracted. In the shaking extraction, for example, it can be extracted while being set in a rotator and rotated in a low temperature chamber such as about 4 ° C.

More specifically, first, pomegranate seeds are prepared. Pomegranate seeds are washed and dried as needed. It is preferable that the drying is sufficiently performed. This is to perform the subsequent pulverization uniformly.

Next, the pomegranate seeds are ground. The crushing method is not particularly limited, and a known crusher such as a ball mill, a hammer mill, a roller mill, a rod mill, a sample mill, a stamp mill, a disintegrator, a mortar, and a blender with a cooling device can be used. Since it is conceivable that the pomegranate seed composition may be decomposed due to heat generated during crushing, the crushing time may be set to several seconds and may be repeated a dozen times.

Next, the pomegranate seeds are crushed to obtain a pulverized product, and then the pulverized product is immersed in various solvents. The solvent in this case is not particularly limited, and the solvent can be appropriately set according to the desired effect. Further, in a preferred embodiment of the method for producing a pomegranate seed extract of the present invention, the solvent is at least one selected from the group consisting of ethanol, methanol, hexane and water. Examples of the solvent include polar and non-polar solvents such as ethanol, methanol, water, hexane, ethyl acetate, chloroform and acetone. Preferably, methanol, ethanol, water and the like can be mentioned.

The immersion can be carried out under gentle stirring. The pulverized product is immersed in various solvents to obtain various solutions. The various solutions may be stirred according to the state of the solution, and the solution may be left as it is in some cases. In the case of stirring, the stirring can be continued for 10 hours to 48 hours, preferably about 1 day (24 hours) without particular limitation.

Then, the pomegranate seed extract can be obtained by separating the supernatant. If necessary, the supernatant is evaporated to dryness. Evaporation to dryness can be carried out using an evaporator on a warm bath at 20 ° C. to 60 ° C., preferably 37 ° C. to 40 ° C. By evaporating to dryness, the pomegranate seed extract can be stored for a long period of time.

The components contained in the pomegranate seeds are sorted according to their physical characteristics by extracting the pomegranate seeds with solvents having different polarities. Therefore, the type and content of the components of the pomegranate seed extract differ depending on the solvent used.

An example of the hair coloring method in the present invention will be described below.

1) Pre-shampoo as appropriate to remove hair styling products and stains.
2) Decolorize by a conventional method. This bleaching step then facilitates the application of the post-bleaching hair coloring agent and makes it possible to realize a design color.
3) A mixture of a post-bleaching hair coloring agent (containing a hair dye component) and a hair cosmetic (containing a basic cuticle swelling agent) applicable to the present invention is applied to the hair by a brush.
4) Cover the applied hair with plastic wrap, heat it with a hair dryer or heat cap, and leave it for about 30 minutes.
5) After 4), if necessary, apply the cuticle care agent sufficiently to the hair and leave it for about 6 minutes.
6) After 5), wash your hair with hot water and shampoo.
7) After towel drying, dry the hair with a hair dryer.

As described above, conventionally, a hair cosmetic containing a somewhat large amount of a hair coloring agent composition + an alkaline agent or the like is mixed with a subject with gray hair, applied, and left to be heated or left unheated. After that, if necessary, a cuticle care agent was applied to wash and finish the hair (leaving time of about 10 to 30 minutes).

On the other hand, in the present invention, for a subject with healthy black hair, after brightening the hair by a bleaching process, a hair cosmetic containing about 1/30 of the conventional amount of composition + alkaline agent is applied. After mixing, applying and leaving with heating or without heating, if necessary, apply a cuticle care agent, wash and finish the hair (leaving time of about 10 to 30 minutes) to change the design color. It has become possible to enjoy with a small amount of dye.

Hereinafter, an embodiment of the present invention will be described, but the present invention is not construed as being limited to the following examples.

Example 1
Regarding the alkaline agent (pH adjuster), from the viewpoint of being weakly alkaline and less likely to cause skin irritation, in this example, the test was conducted using ammonium hydrogen carbonate as an example.

In addition, about 80% of human hair is composed of keratin protein derived from amino acids, L-cysteine is an amino acid that is also abundant in the hair, and L-cysteine and its salts keep the hair moisturized and soft. I tried to mix it for the purpose. Typical basic amino acids are L-arginine, L-lysine, and L-histidine, but these are known to flow out when damaged, and 0.01 to 0.5 mass of basic amino acids and salts thereof. % Was found to be preferable.

Table 1 shows component examples of the hair coloring agent composition according to one embodiment of the present invention.

The adjustment method is as follows.

Adjustment method:
1. 1. The aqueous phase in Table 1 is heated to 75-77 ° C. with stirring.
2. 2. The oil phase in Table 1 is stirred while heating to 75 to 79 ° C. to make it uniform.
A dye is added to the aqueous phase heated to 3.75 to 77 ° C. to make it uniform, the oil phase is added to emulsify, and the mixture is stirred until uniform.
4. The contents are slowly cooled, and when the temperature drops below 43 ° C, preservatives, a cooling component, an anti-inflammatory component, and an amino acid group are added and stirred until uniform, and cooled to 32 ° C or lower.

The following models and electrodes were used for pH measurement.
Model of pH meter: F-71 (HORIBA, Ltd.)
Electrode of pH meter: Type 9615 (HORIBA, Ltd.)

Further, in Table 1, the same test was conducted when "thioglycerin" was changed to "Na oxymethylene sulfoxylate" (manufacturer: Tokyo Chemical Industry Co., Ltd., 0.5% of the blending amount).

In this way, when the post-bleaching hair coloring agent of the present invention was adjusted and a color fading test was performed on the hair bundle, it was found to be extremely excellent in color fading.

Conventionally, when a hair coloring agent containing no para-phenylenediamine is applied and left to stand, the base color is a basic dye and an HC dye, which are considered to be safer than an oxidation dye, but because they are dyed on the hair. There was a drawback that the color retention after dyeing was poor and the color was easily discolored by repeated shampooing. Compared to conventional hair coloring agents, the post-bleaching hair coloring agent of the present invention not only makes it easier for the base color to penetrate, but also does not contain acid dyes, so it does not care about adhesion to the scalp and hair from the new part. It turned out that it can be applied up to the point.

As described above, the hair coloring agent and the like of the present invention are compared with conventional hair coloring and hair manicure in performing hair dyeing, and 1) the hair strength is lowered in those who have damaged hair due to repeated dyeing. , Loss of elasticity and thinning of hair (conventional hair color), 2) If scalp rash occurs, the rash part is dyed and it is quite difficult to remove (conventional hair manicure), and more color It has been found to provide hair cosmetics with good longevity and penetrating dyeing power. That is, it was also found that the present invention has safety as well as color retention.

Example 2
The penetration of major basic dyes applicable to the present invention was compared. Hair Commercially available 100% untreated gray hair (product number: BS-C, manufactured by Burax Co., Ltd.) A hair sample having a length of 30 cm was divided into three equal parts to be dyed. For Basic Red 51, Basic Brown 16 and 17, the pigment was dissolved in purified water by 0.2%, and the pH was adjusted to alkaline using 25% ammonia water (manufactured by Wako Pure Chemical Industries, Ltd.), and 3-mercapto as thioglycerin. A 0%, 1% and 3% solution of -1,2-propanediol (manufactured by Wako Pure Chemical Industries, Ltd.) was prepared. The optimum value of alkalinity is around pH 7.5 to 10.0, but there are differences depending on the dye, and some dyes cause precipitation in the solution if the pH is raised too much. Basic Blue 75, 77, 99, Basic Violet 2, and Basic Yellow 57 are amidobetaine-type amphoteric tenside coconut oil fatty acid amide propyl betaine solution (product number: softazoline CPB-R, Kawaken Fine Chemicals) to improve dye solubility. (Manufactured by Wako Co., Ltd.) Dissolve 0.7% of dye in 5.0%, add purified water, and use 25% ammonia water (manufactured by Wako Pure Chemical Industries, Ltd.) to adjust the pH to alkaline, and 3-mercapto-1. , 2-Propanediol 0%, 1%, 3% solutions were prepared. A hair sample obtained by dividing one gray hair into three equal parts is immersed in a 0%, 1%, or 3% solution of 3-mercapto-1,2-propanediol of each dye, and left for 30 minutes in a constant temperature bath at 40 ° C. Stained. The hair sample was freeze-embedded with PVA resin, and then a hair cross-section sample (section thickness: 10 μm) was prepared using a microtome. Then, they were placed on a slide glass as a sample for microscopic observation and compared with a microscope (Fig. 1).

As shown in FIG. 1, the degree of penetration of the dye into the hair sample is deepest in all the dyes when 3-mercapto-1,2-propanediol is 3% (the range where the color is dark from the outer periphery of the cross section). Is the largest). In particular, it was more clear that the dyes of Basic Brown 16 and Basic Blue 77 had good penetration.

Example 3
Hair using the dyes of Basic Brown 16 and Basic Blue 77, which had good penetration, 100% untreated hair on the market (product number: BS-C, manufactured by Burax) was kept at a constant temperature of 40 ° C in the following formulation example (Table 2). The hair was dyed dark brown by leaving it in a tank for 30 minutes. Table 2 shows examples of ingredients and formulations.

The hair sample was freeze-embedded with PVA resin, and then a hair cross-section sample (section thickness: 10 μm) was prepared using a microtome. Then, as a result of placing it on a slide glass as a sample for microscopic observation and comparing it with a microscope, 0% and 0.5% of sodium hydroxymethanesulfinate when Basic Brown 16 0.2% and Basic Blue 77 0.2% were mixed to make a dark brown color. Good observation results were obtained with an optical microscope of hair cross-section samples treated in 1%, 3%, 5%, 7% and 10% solutions. That is, it was found that when sodium hydroxymethanesulfinate was used, the effect of increasing the dyeing power was low like that of thioglycerin, but the color fading due to the number of washings could be prevented by adding it than when not adding it.

Then, remove the chemical solution with lukewarm water and dry with shampoo and dryer. Created bleached hair. The hair coloring level scale sold by the Japan Hair Color Association showed 9 levels.

2) Cream type commercial decolorizing agent
"Fiyore BL Color Lightener (manufacturer and distributor: Shisei Chemical Co., Ltd.)" as agent I and 6% commercially available hydrogen peroxide as agent II are mixed at a ratio of 1: 1 to make 100% untreated human black hair on the market. It was applied to the bundle and left at 25 ° C. for 30 minutes, after which the chemical solution was removed with lukewarm water and dried with shampoo and a dryer. This process was repeated 5 times to create decolorized hair. The hair coloring level scale sold by the Japan Hair Color Association showed 11 levels.

3) Powder type commercially available decolorizing agent
"Number Three BP (manufacturer and distributor: Number Three Co., Ltd.) as Agent I and 6% of commercially available hydrogen peroxide as Agent II are mixed at a ratio of 1: 3 to make 100% commercially available human black hair and untreated hair bundles. The hair was applied, left at 25 ° C for 30 minutes, then the chemical solution was removed with lukewarm water, and dried with shampoo and a dryer to create decolorized hair. The hair coloring level scale sold by the Japan Hair Color Association showed 10 levels.

The hair coloring agent composition of the present invention for the fashionable dyeing formulation prepared in Example 1 for these three types of hair bundles, and "Illumina Color TWI-6 (manufacturer and distributor: Proctor & Co., Ltd.)" which is an oxidative hair dyeing agent for fashionable dyeing.・ Gambling Japan Co., Ltd. ”,“ Non-diamine Helper DF / P-08 Manufacturer: Estate Chemical Co., Ltd. ”is used to dye the hair, and the dyed hair bundle is a friction tester that gives the finished texture. (Manufactured by Kato Tech Co., Ltd.), the brilliance of the hair is measured by a gloss meter (manufactured by Nippon Denshoku Kogyo Co., Ltd.), and the degree of damage to the hair is used as the retained water content. ) Was used for measurement.

A sensory evaluation such as "stroking" the texture of hair was measured (average value) using "KES-SE friction tester (manufactured by Kato Tech Co., Ltd.)" with "smoothness" as the coefficient of friction. The measurement was performed in a constant temperature and humidity chamber, and the measurement environment temperature and humidity was 20 ° C / 61% RH. Table 3 shows the evaluation results regarding the coefficient of friction.

Therefore, it was found that the post-decolorization hair color composition and hair coloring agent of the present invention have a low value and excellent smoothness even after any of the decolorization steps 1) to 3). did.

Example 5
Next, the same hair bundles as in Example 4 were measured using a glossiness measuring device (VG7000) manufactured by Nippon Denshoku Kogyo Co., Ltd., and the measured values (mean values) at an incident angle of 85 ° are shown below. The results are shown in Table 4.

Therefore, even after any of the bleaching steps 1) to 3), the post-bleaching hair color composition and hair coloring agent of the present invention have a high numerical value and, by extension, good gloss. found.

Example 6
It is said that the same hair bundle as in Example 4 is heated at 65 ° C. for 40 minutes using a constant temperature dryer (SDN27P) manufactured by Sanshosha, and the weight loss is used as the primary evaporation water, and the total water contained in the hair is further evaporated. The values (mean values) obtained by heating at 180 ° C for 30 minutes are shown below. Specifically, the water content of the hair was measured using an electronic moisture meter (EB-340MOC; manufactured by Shimadzu Corporation) according to the water evaporation amount measurement method. The results are shown in Table 5.

As a result of Table 9, since the primary evaporation water assumes the temperature of the hair dryer, the water content of the product of the present invention is superior to that of the other two products, and the water content of the product of the present invention is higher than that of the other two products. From the high price, it can be seen that the use of the product of the present invention increases the moisture content of the hair as compared with the other two products.

Generally, the fashionable color is based on an oxidative hair dye that develops a color with an oxidant dye and an oxidant such as hydrogen peroxide, but the present invention uses a basic dye that does not need to react with the oxidant or the like to form a composition. When you dye your hair in a two-step process of adjusting the amount of dye, bleaching, and dyeing your hair, you can "design" your hair color using multiple shades and light and darkness called "design color". It has become possible to partially change the brightness to give a three-dimensional effect, or to dye a part to create points.

Further, from the above results, it was found that when thioglycerin or the like is blended, it is possible to dye hair having good toughness characteristics without raising the pH or heating. It was also found that it is more effective to add thioglycerin or the like and to increase the heating and pH. In the case of the dyes Basic Blue 99 and Basic Tea 16, it is possible to dye hair with better robustness as the pH is raised to around pH 10, while in the case of Basic Blue 77, the pH is 8 or higher. It was found that when raised, the pigment broke and the color changed, resulting in weak hair dyeing.

As described above, it has been found that the addition of thioglycerin or the like in the coloring of hair or the like makes it easier for the dye to enter the hair.

According to the present invention, a coloring method that does not easily damage hair, can reduce skin disorders, and allows dyes to easily enter hair is easy to spread and has high industrial utility value.
