Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a straight perm second
It is related to agents. More specifically, the present invention relates to a second straight perm agent capable of simultaneously performing straight perm and hair manicure in a short time, and having no coloration on the skin such as scalp due to the hair manicure.

[0002]

2. Description of the Related Art Conventionally, the purpose of a straight perm agent has been to straighten curly hair or curly hair, or to straighten the waves obtained by a permanent wave agent. recent years,
Straight hair is especially popular among young people, many of whom use straight perm agents. Similarly, among young people, a hair nail polish, that is, a semi-permanent hair coloring agent using an acid dye is also frequently used. In the straight perm, a reducing agent such as thioglycolate is the main agent, and a first straight perm agent containing an alkaline agent such as ammonia and monoethanolamine is applied. At this time, the reducing agent in the first agent acts to break the disulfide bond of cystine in the hair, and the action of the alkaline agent causes the hair to swell. After that, the first agent is washed off, and a straight perm second agent treatment containing an oxidizing agent such as bromate as a main agent is performed. Hair manicure is made of acid dye, solvent such as benzyl alcohol, and acid such as lactic acid for adjusting pH to about 3 to 4 to obtain sufficient hair dyeing power. After leaving it for a certain period of time, it is rinsed off and dyed.

[0003]

However, there are some problems in performing both the straight perm and the hair manicure. That is, in general, first, a straight perm was applied, and then a hair manicure was applied.
It took a long time of 4 hours, which reduced the turnover ratio of customers at the beauty salon. In addition, long-term treatment was also a great pain for the subject. Further, the hair manicure also colored the skin such as the scalp, which was very nervous for the practitioner. On the other hand, in order to perform the straight perm and the hair manicure at the same time, a simultaneous treatment agent prepared by mixing a sulfite-based straight perm first agent with an acid dye-based hair dye is commercially available. However, such a product had a very weak straightening effect, which was no different from simply applying a hair manicure. That is,
In the conventional technology, it is impossible to perform straight perm and hair manicure at the same time, and the same straight effect and hair dyeing effect can be obtained as the same effect as when the ordinary straight perm agent and hair manicure are individually applied. there were.

[0004]

[Means and Actions for Solving the Problems] In such a situation, as a result of earnest research by the present inventor, the present inventors have conducted straight perm and hair manicure at the same time by adding an acid dye to the second agent for straight perm. It has been found that the straightening effect and the hair dyeing power are the same as those obtained when the ordinary straight perm agent and the hair manicure are individually treated. Furthermore,
The present invention has been completed by finding an unexpected effect that there is no coloring of the skin such as the scalp by hair manicure. That is, the present invention is a straight perm second agent characterized by containing 0.1 to 5.0% by weight of an acid dye.

Hereinafter, the configuration of the present invention will be described in detail. Examples of the acidic dye used in the product of the present invention include nitro dye, azo dye, nitroso dye, triphenylmethane dye, xanthene dye, quinoline dye, anthraquinone dye and indigo dye.

No. 230, Red No. 231, Red No. 232, Orange No. 205, Orange No. 207, Yellow No. 202, Yellow No. 203
No. 201, Green No. 201, Green No. 204, Green No. 205, Blue No. 202, Blue No. 203, Blue No. 205, Brown 201
No., Red No. 401, Red No. 502, Red No. 503, Red No. 504, Red No. 506, Orange No. 402, Yellow No. 402
No. 403, Yellow 403, Yellow 406, Yellow 407, Green 401, Green 402, Purple 401 and Black 401
No. 401 and the like, and preferably black No. 401 and purple 40
No. 1, orange 205, yellow 403 and red 401. The blending amount is 0.1 to 5% by weight. If it is less than 0.1% by weight, a sufficient hair dyeing effect cannot be obtained, and if it is more than 5% by weight, there is a risk of dyeing on the background. The lower limit of the blending amount is preferably 0.2% by weight, and by blending 0.2% by weight or more, a sufficient hair dyeing effect can be obtained. The upper limit is preferably 1% by weight, and when it exceeds 1% by weight, the hair dyeing effect is less increased.

As the oxidizing agent, bromate, perborate,
Hydrogen peroxide and the like can be mentioned. The blending amount is 5 to 10% by weight. If it is less than 5% by weight, a sufficient straightening effect cannot be obtained, and if it exceeds 10% by weight, the improvement of the straightening effect is small. The lower limit of the blending amount is preferably 6% by weight, and by blending 6% by weight or more, a sufficient straightening effect can be obtained. The upper limit is 8% by weight
Is preferable, and when it exceeds 8% by weight, the increase of the straight effect becomes small.

Hair dyeing power can be improved by adding a solvent such as ethanol, isopropyl alcohol, 1,3-butylene glycol, glycerin, polyethylene glycol or diglycerin. The blending amount is 0.1 to 10% by weight. If it is less than 0.1% by weight, sufficient hair dyeing power cannot be obtained, and if it exceeds 10% by weight, improvement in hair dyeing power is small.

Further, a pH adjusting agent such as citric acid, sodium citrate and phosphoric acid can be added.
It is preferable to add a regulator to adjust the pH to 4-8. Furthermore, oils and fats, higher alcohols, silicones, cationic surfactants, anionic surfactants, nonionic surfactants, amphoteric surfactants, fragrances, hair protectants, polypeptides, ultraviolet absorbers, Preservatives, humectants, cationic polymers, anionic polymers, nonionic polymers and the like, which are generally used for the straight perm second agent, can be blended within a range that does not impair the effects of the present invention.

It is preferable to use a cationic surfactant in combination with an anionic polymer because natural dyeing and excellent finish can be obtained. Examples of the cationic surfactant include alkyl trimethyl ammonium chloride, lauryl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, cetyl trimethyl ammonium bromide, stearyl trimethyl ammonium chloride, stearyl trimethyl ammonium bromide, lauryl trimethyl ammonium bromide and dialkyl dimethyl chloride. Examples thereof include ammonium, dicetyldimethylammonium chloride, distearyldimethylammonium chloride, dicocoyldimethylammonium chloride, myristyldimethylbenzylammonium chloride and stearyldimethylbenzylammonium chloride. The blending amount is 0.1 to 10% by weight, and if it is less than 0.1% by weight, a sufficient effect cannot be obtained, and if it exceeds 10% by weight, the effect does not change and it is not economical. Examples of the anionic polymer include sodium carboxymethyl cellulose, xanthan gum, carrageenan, sodium alginate, pectin, farseran, gum arabic, gatch gum, tragacanth gum and agar powder, but sodium carboxymethyl cellulose and xanthan gum give natural dyeing and excellent finish. From the point of, it is preferable. The blending amount is 0.1 to 10% by weight, and if it is less than 0.1% by weight, a sufficient effect cannot be obtained, and if it exceeds 10% by weight, the effect does not change and it is not economical. The weight ratio of cationic surfactant to anionic polymer is 1:10.
The range of 10 to 10 is preferable from the viewpoint of natural dyeing and excellent finish.

The first straight perm agent used with the product of the present invention is generally used. That is, thioglycolic acid, thioglycolate, cysteine, cysteine derivatives, reducing agents such as sulfites and hydrogen sulfites, and alkaline agents such as ammonia, monoethanolamine, ammonium carbonate, sodium carbonate, sodium bicarbonate and sodium hydroxide. , Reaction modifiers such as dithiodiglycolic acid and dithiodiglycolic acid salts,
In addition, oils and fats, higher alcohols, silicones, cationic surfactants, anionic surfactants, nonionic surfactants, amphoteric surfactants, fragrances, coloring agents, hair protecting agents, chelating agents, poly Peptides, ultraviolet absorbers, preservatives, moisturizers, cationic polymers, anionic polymers, nonionic polymers and the like can be appropriately added.

The present invention is not limited to the dosage form but is applicable to the second type of straight perm agent of any dosage form such as cream, gel, emulsion, transparent liquid and powder. is there.

According to the present invention, the action of the first agent causes the hair to swell and makes it easier for the substance to be taken into the inside of the hair. Even if the pH is set, a sufficient hair dyeing effect can be obtained, and coloring of the skin such as the scalp can be prevented. Moreover, straight perm and hair manicure can be performed at the same time, which can greatly reduce the time.

[Table 2]

[Table 3]

Next, as shown in FIG. 1, a straight perm and a hair manicure are simultaneously applied by using the product of the present invention, and as shown in FIG. A comparison was made with the case of manicure. Straight perm No. 1 shown in Figs.
The agents used in Table 1 were both. After that, a straight perm second agent treatment was performed by using Example 1 of Table 2 in the method of FIG. 1 and Comparative Example 1 in the method of FIG. FIG.
In the conventional treatment method shown in (1), hair manicure treatment was then performed using Formulation Example 1 in Table 3. as a result,
When the straight perm and the hair manicure treatment were performed as shown in FIG. 2, it took 185 to 235 minutes in the conventional treatment method. On the other hand, as shown in FIG. 1, when the second straight perm agent according to the present invention was used, the straight perm and hair manicure treatment could be performed only in the time (125 to 155 minutes) required for the conventional straight perm treatment. Therefore, by using the second straightening agent of the present invention, the treatment time was shortened by 1 hour or more as compared with the conventional technique. No significant difference was found in the finished straight effect and hair dyeing power. Even when Example 2 was used instead of Example 1, the same effect as that of Example 1 was obtained.

Next, in order to evaluate the coloring of the skin of scalp and the like of the straight perm second agent of the present invention and ordinary hair nail polish, a coloring test was performed on the inner side of the upper arm. Apply each test solution to the inner part of the upper arm so that the diameter is approximately 1 cm.
It was left at room temperature for 0 minutes and then washed with slightly warm water. When Example 1 was used, the color was completely removed by washing with water.
When Example 2 was used instead of, the color was almost completely washed off with water, and then lightly rubbed with soap to completely remove the color. On the other hand, in the case where the hair nail polish formulations 1 and 2 shown in Table 3 were used in the conventional treatment method, all were washed with water,
After that, the color did not fade even after scrubbing with soap. Therefore, it is clear that the skin such as the scalp is not colored by using the second straight perm agent of the present invention.

[0018]

EFFECT OF THE INVENTION Since the straight perm and the hair manicure can be performed at the same time, the operation time can be shortened and the scalp and other skins are not colored.
