発明の背景
従来から、必須成分として、第１剤に酸化染料
を含有し、第２剤に過酸化水素を含有する水系の
２剤形で、使用時に第１剤および第２剤を混合し

毛髪を膨潤させて染料分子の毛髪内部への浸透を
容易にし、かつ、過酸化水素からの発生期の酸素
の発生を促進させるために、アンモニアや、モノ
−、ジ−またはトリアルカノールアミンのよう
な、いわゆるアルカリ剤が配合されており、それ
により、染毛効果の発現向上が図られている。
しかしながら、かかる染毛剤には使用上、種々
の問題がある。例えば、該アルカリ剤の配合によ

により、使用時に不快感を伴い、香料による芳香
付与も困難であるという問題がある。さらに、ア
ルカリ剤の配合により毛髪が損傷しやすく、こと
に、モノ−、ジ−またはトリエタノールアミンは
不揮発性で毛髪に残留しやすく、使用後に毛髪の
光沢が失なわれたり、引張強度が低下したり、パ
サついたりする問題がある。また、過酸化水素の
脱色作用による毛髪の損傷の問題もあり、一方、
白髪の染色に用いる場合は黒髪までも脱色し、髪
全体を色あせた状態にする問題もある。加えて、
染毛時間が20〜40分と比較的長く、操作も面倒で
あるという問題もある。
また、かかる２剤形の染毛剤も含め、一般に、

れらの等量混合物はPH7.7であつた。 DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gray hair dye, and more particularly, to an aqueous two-dose product consisting of a first part containing an oxidative dye as an essential component and a second part containing hydrogen peroxide as an essential component. The present invention relates to a hair dye useful for gradually reducing the appearance of gray hair in humans without damaging the hair. BACKGROUND OF THE INVENTION Conventionally, the first part contains an oxidation dye and the second part contains hydrogen peroxide as essential ingredients, and the first part and the second part are mixed at the time of use. A dye that is applied to hair, penetrates the oxidative dye molecules into the hair, bleaches the hair with oxygen during the nascent stage where hydrogen peroxide is generated, and oxidatively polymerizes the oxidative dye to develop color, thereby dyeing the hair. It is known as a hair conditioner. The first agent of such a hair dye generally includes:
Ammonia and mono-, di-, or trialkanolamines are added to swell the hair to facilitate the penetration of dye molecules into the hair and to promote the evolution of nascent oxygen from hydrogen peroxide. It contains a so-called alkaline agent, which improves the hair dyeing effect. However, such hair dyes have various problems in use. For example, due to the combination of the alkaline agent, the pH of the first agent exceeds 9, usually very high, 10 to 11, and exhibits strong irritation. Further, when ammonia is used as an alkaline agent, its strong irritating odor causes discomfort during use, and there is a problem that it is difficult to impart fragrance with perfume. Furthermore, the combination of alkaline agents tends to damage the hair, and in particular, mono-, di-, and triethanolamines are non-volatile and tend to remain in the hair, causing the hair to lose its luster and reduce its tensile strength after use. There is a problem that it may become dry or dry. There is also the problem of hair damage due to the bleaching effect of hydrogen peroxide.
When used to dye gray hair, there is also the problem that even black hair is bleached, leaving the entire hair in a faded state. In addition,
Another problem is that the hair dyeing time is relatively long at 20 to 40 minutes, and the operation is troublesome. In addition, in general, including such two-dose hair dyes,
Conventional hair dyes strongly dye the hair all at once, resulting in a sudden change in the appearance of the hair, creating a sense of discomfort, which is particularly problematic when dyeing gray hair. The present inventors have solved the problems with conventional hair dyes, especially hair dyes that are composed of two aqueous formulations of oxidation dye and hydrogen peroxide, and have developed a hair dye that is highly effective in dyeing gray hair. We conducted extensive research to find a hair dye that works. As a result, they found that the objective could be achieved by adjusting the pH of the hair dye to a specific range without using the above-mentioned alkaline agents, and were able to complete the present invention. Summary of the Invention The present invention provides one or more selected from the group consisting of paraphenylene diamine, N-phenylparaphenylene diamine, and toluene-2,5-diamine sulfate, and ortho-aminophenol, meta-aminophenol. and para-aminophenol, the first agent having a pH of 6.6 to 9 and hydrogen peroxide, which contains an oxidation dye consisting of one or a combination of two or more selected from the group consisting of para-aminophenol as an essential component, and does not contain any alkaline agents other than the oxidation dye. PH1~ with essential ingredients
It is a water-based two-dose form consisting of a second agent of 7.
The present invention provides a novel gray hair dye characterized by having a pH of 6.6 to 8.3 when the agent and the second agent are mixed. With the hair dye of the present invention, there is no problem of strong irritation due to high pH or irritating odor of alkaline agents.
By adjusting the pH, hair damage and excessive bleaching can be prevented, and hair can be dyed well. In particular, the hair dye of the present invention has been found to be suitable for a novel hair dyeing method referred to herein as "cumulative hair dyeing". In other words, the cumulative hair dyeing method is
During the initial period of hair dyeing, for a short period of time with hair dye, e.g.
Dye hair for 1 to several minutes at appropriate intervals, e.g.
By repeating the procedure two to several times at intervals of ~3 days, the hair is dyed little by little, gradually and cumulatively, and after the hair has been dyed to the perfect color, the newly growing hair is dyed. Longer spacing, e.g. 1
- A method of repeating hair dyeing once every few weeks,
This makes it possible to easily dye the hair in a short period of time, and also eliminates the discomfort caused by dyeing the hair strongly all at once. Detailed Description of the Invention The first agent of the hair dye of the present invention is characterized in that it contains the above-mentioned specific oxidation dye as an essential component, contains no other alkaline agents, and has a pH in the range of 6.6 to 9. All of these oxidative dyes become black to brown through oxidative polymerization, and are generally 0.5 to 5.0% (wt%, same hereinafter) based on the total amount of the first agent, preferably,
It is blended in a proportion of 1.0 to 3.0%, more preferably 1.5 to 2.5%. Note that these oxidative dyes may be further combined with resorcin, catechol, para-amino orthocresol, and the like. Alkaline agents other than oxidation dyes include ammonia,
Commonly used organic alkaline agents such as mono-, di- or trialkanolamines, as well as inorganic alkaline agents such as sodium hydroxide, potassium hydroxide, ammonium citrate, sodium citrate, ammonium bicarbonate, potassium oxalate. Organic alkali salts such as sodium phosphate, inorganic alkali salts such as potassium phosphate are included, and these alkaline agents are used in the hair dye of the present invention to remove irritation and irritating odor and prevent hair damage. Excluded from the formulation ingredients. If the pH of the first agent is lower than 6.6, the hair dyeing effect due to the nascent oxygen from hydrogen peroxide in the second agent cannot be expected, and if it exceeds 9, the hair bleaching effect due to the nascent oxygen. is excessive, so it is set in the range of 6.6 to 9. Normally, due to the alkalinity of the oxidation dye, it is possible to maintain this pH range without adjusting the pH, but if necessary, acid addition such as organic acids such as citric acid and malic acid, or inorganic acids such as hydrochloric acid and phosphoric acid may be necessary. You can also adjust the PH. The second agent of the hair dye of the present invention is characterized in that it contains hydrogen peroxide as an essential component and has a pH in the range of 1 to 7. Hydrogen peroxide is generally 1% based on the total amount of the second agent.
It is blended in a proportion of ~10%, preferably 3-7%, more preferably 5-6%. If the pH of the second agent is too high, hydrogen peroxide will become unstable, so
The range shall be 7. Normally, no particular pH adjustment is required, but if necessary, the pH can be adjusted by adding an acid as described above.
can be adjusted. Furthermore, in the present invention, the pH when the first agent and the second agent are mixed is 6.6 to 8.3, preferably 7.
~8 is required. If the pH is lower than 6.6, the hair dyeing effect due to the polymerization reaction of the oxidative dye cannot be expected, and if it exceeds 8.3, bleaching of black hair will occur.
Not desirable as a gray hair dye. This PH is determined by mixing the first agent and the second agent within the above-mentioned PH range in the mixing ratio when using this type of dye, for example, the weight ratio of the first agent:second agent is 1:4 to 4. :1, preferably 1:2 to 2:1. Both the first agent and the second agent of the hair dye of the present invention can be made into dosage forms such as aqueous solutions, emulsions, creams, pastes, and gels according to conventional methods, such as shampoo type, treatment type, pre-treatment type, etc. It can be used as a treatment type hair dye.
Other ingredients are not particularly limited, and include various solubilizers, emulsifiers, solvents, wetting agents, sequestering agents, foaming agents, foaming aids, oils and fats, waxes, hydrocarbons, fatty acids, alcohols, A suitable combination of alcohols, ester oils, fragrances, etc. can be used. The hair dye of the present invention can be used in the same manner as conventional two-part hair dyes. For example, when used, the first part and the second part are mixed in the proportions described above, and the hair dye is applied to the hair. Apply evenly, leave for 20 to 40 minutes, then rinse and shampoo. Further, as mentioned above, it is particularly preferable to use the hair dye of the present invention in a cumulative hair dyeing method. For example, when taking a bath or before shampooing, the first part and the second part are similarly mixed, and the hair dye is uniformly applied to the hair. After application, leave for 1 to 5 minutes, then rinse lightly and shampoo as usual. Repeat this procedure 2 to 5 times every 2 to 4 days, and once the gray hair is no longer noticeable, dye your hair in the same way once every 1 week to 1 month to dye the newly growing gray hair. do. This makes it possible to easily dye gray hair without any discomfort. Experiments Next, we will show the results of tests on the relationship between pH and hair damage, irritation, hair bleaching effect of hydrogen peroxide, hair dyeability, and fastness. (1) Relationship between PH and hair damage The breaking strength of hair treated with hair dyes of various PH was measured. The formulation of the hair dye used is as follows. Part 1 (paste) Ingredients Weight % Liquid paraffin 15.0 Cetyl alcohol 3.0 Polyoxyethylene (6) cetyl ether 1.5 Polyoxyethylene (18) lauryl ether 0.4 Propylene glycol 5.0 Thioglycolic acid 0.1 Paraphenylene diamine 2.0 Orthoaminophenol 0.5 Meta Aminophenol 1.0 Fragrance 0.3 28% ammonia water or citric acid Adjust to specified pH Purified water Adjust to 100% Note) PH7.8 when ammonia water or citric acid is not added 2nd agent (aqueous solution, PH3.2) Ingredients Weight % 35% hydrogen peroxide solution 16.0 Citric acid 0.2 Purified water 83.8 0.2 g of a mixture of equal amounts of the first and second agents was applied to 2 g of untreated blonde hair, left at 25°C for 20 minutes, and then rinsed with water. . This hair dyeing process was repeated three times, using 30 treated hairs for each hair dye, and the breaking strength (strength per average cross-sectional area) measured with a Tensilon meter (manufactured by Toyo Baldwin) while immersed in a water bath. was measured. The results are shown in the attached Figure 1. Figure 1 shows the change in breaking strength due to changes in PH, with the vertical axis showing the breaking strength (average of 30 pieces) (Kg/cm 2 ), and the horizontal axis showing the pH at the time of mixing the first and second agents. It is a graph. As is clear from FIG. 1, when the pH exceeds 8.5, the breaking strength rapidly decreases, indicating that hair damage progresses rapidly. (2) Relationship between PH and irritation Using 0.1 ml of a mixture of equal amounts of the first and second agents of the same formulation as in the test in (1) above, rabbit ocular mucosa was stimulated. After 48, 72, 96 and 168 hours, judgment was made using the Draize method reaction evaluation table (Draize, JH, Woodard, G. and
Calvery, H.O., J.Pharmacol.Exp.Therap.
82, 377-390 (1944)), and the total score was graded using the method of Kay et al. The results are shown in Table 1. [Table] As shown in Table 1, irritation increases rapidly when the pH exceeds 8.5. (3) Relationship between PH and the hair bleaching effect of hydrogen peroxide After treating untreated Japanese hair with the following treatment solution at a bath ratio (hair/treatment solution) of 4 g/40 ml at 25°C for 20 minutes, Rinse with water. This process was repeated three times, and the degree of decolorization was evaluated by measuring the reflected light using a reflection type spectrophotometric colorimeter (manufactured by Murakami Color Research Institute). Treatment liquid Ingredients Weight % 35% hydrogen peroxide solution 8.5 28% ammonia water or citric acid Adjusted to specified pH Purified water Adjusted to 100% Note) PH4.6 without adding ammonia water or citric acid Results are shown in the attached page. Shown in Figure 2. Figure 2 is a graph showing changes in reflectance due to changes in pH, with reflectance (%) on the vertical axis and wavelength (nm) on the horizontal axis, with curves 1 to 1.
