Description

  The present invention relates to a shaping tool for straight permanents and a straight permanent processing method using the same.

  Conventionally, a hair iron for straight perm is known as a shaping jig for applying straight perm to hair (Patent Document 1 and Patent Document 2). This hair iron incorporates an electric heater and is provided with uneven surfaces that mesh with each other. The curly hair is sandwiched between the concave and convex surfaces that engage with each other, and the heat of the electric heater makes the hair easy to perm and become soft. Further, the pressing force when sandwiched between the concave and convex surfaces exerts a correction force so that the curled hair becomes straight hair. For this reason, straight perm can be applied by pinching curly hair several times with this curling iron, and finally lightly squeezing from the root of the curly hair toward the hair tip.

  On the other hand, similarly to the permanent wave, there is also known a straight permanent processing method in which processing is performed with two types of liquids (so-called first liquid and second liquid) (for example, Patent Document 3). The first solution contains a reducing agent and an alkaline agent. The alkaline agent binds to an acidic amino acid in a polypeptide that constitutes hair, and bonds between an acidic amino acid that crosslinks polyamides and a basic amino acid. (Hereinafter referred to as “salt bond”). Further, the reducing agent contained in the first liquid reduces and cleaves “disulfide bonds” that crosslink the polyamides constituting the hair. In this way, the hair in which the two bonds of “salt bond” and “disulfide bond” are cut by the first liquid is held in a state of being stretched straight on a thin plate-shaped shaping jig. Thus, curly hair is corrected to straight hair. Thereafter, a second liquid further containing an oxidizing agent is applied to the hair, the disulfide bonds cut by the first liquid are regenerated, and the shape of the hair that has been brought into a straight hair state is fixed. Then, the hair is washed to wash away the second liquid, and the salt bonds are regenerated by the acid rinse agent. Thus, the hair straightened with the first liquid is constantly maintained in shape by the second liquid.

However, when straight perm is performed with the above-described hair iron, the pressing force against the hair is partially different, so that the hair is easily damaged by heat in the strongly pressed portion. In addition, in order to uniformly treat the hair, it is necessary to separate the hair little by little and repeat the pressing. Therefore, the treatment takes time and the amount of labor of the practitioner is very large. Both the practitioner and practitioner It was painful.
On the other hand, the straight permanent treatment method in which treatment is performed with the first liquid and the second liquid is inferior in work efficiency because the treatment with the first liquid takes time.

  The present invention has been made in view of the above-described conventional circumstances, and is a straight permanent shaping jig and a straight tool that have a short processing time, a small amount of labor for the practitioner, and less pain for the practitioner and practitioner. Providing a permanent processing method is an issue to be solved.

The shaping tool for straight permanents of the present invention is characterized by comprising a thin plate-shaped shaping jig main body and an electric heater provided in the shaping jig main body.
In the shaping tool for straight permanents of the present invention, since the electric heater is provided inside the shaping jig main body, the hair set in the shaping jig main body can be heated. For this reason, when the hair is attached to a shaping tool for straight permanents and the first liquid performs a salt bond cleavage reaction or disulfide bond cleavage reaction, the cleavage reaction is promoted, and the treatment with the first liquid is accelerated. Can be done. Moreover, since it is not necessary to perform the operation | work which repeats the press to hair like the hair iron for straight permanents, there is little work amount of a practitioner and work efficiency becomes favorable.
Since the shaping jig of the present invention is thin, it can be reduced in weight, and can be used with a pin or the like attached to the hair.

  The shaping tool for straight permanents of the present invention preferably has flexibility. If it is like this, even if a practitioner touches the shaping tool for straight permanents during work, it does not interfere with the work by bending. Moreover, even if the shaping tool for straight permanent hits the patient during the treatment, it is not so painful. Furthermore, if the hair is attached to a shaping tool for straight permanents, the head part is wound on the outside or inside, and the hair is curled into the inside or outside by winding it with a hairpin or the like. It becomes possible.

  In the shaping tool for straight permanents of this invention, it is preferable to provide the opening for penetrating hair to the upper end of a shaping jig main body. If this is the case, when attaching the hair to a shaping tool for straight permanents, the head hair can be inserted from the inside of the opening to the outside and the hair can be easily fastened with a hair clip or the like from the periphery of the opening. . For this reason, it becomes difficult for the shaping tool for straight permanents to slip off from the hair. The straight perm shaping jig of the present invention is also provided with an electric heater, and the weight increases accordingly. Therefore, it is particularly effective to fasten the hair from the periphery of the opening with a hair clip or the like. The opening may have a notch. In this case, the hair can be easily inserted into the opening by inserting the hair from the notch.

Moreover, it is preferable that the said opening has the opening upper edge contact | abutted from the front side to the hair to penetrate, and the opening lower edge contact | abutted from the back side to the hair to penetrate. If this is the case, the hair inserted through the opening is brought into contact with the upper edge and the lower edge of the opening from different sides, making it easier for the hair to get caught in the opening. When this is done, it is possible to reliably prevent the shaping jig from falling off the hair.
Moreover, it is also preferable that the terminal of the electric heater is attached to the upper edge of the shaping jig main body. If it is like this, when connecting the lead wire from a power supply to a terminal, it is hard to get in the way of treatment.

The shaping tool for straight permanents of the present invention can be used as follows.
That is, the straight perm treatment method according to the present invention includes a mounting step in which a part of the hair is separated and aligned and mounted on one side of the straight perm jig according to claim 1, and the straight perm jig A first permanent solution for hair containing a reducing agent, an alkaline agent composed of arginine and / or lysine and water is attached to the hair on which the hair is worn, and heated with an electric heater provided inside the shaping jig body. A first liquid treatment step, and a second liquid treatment step in which the hair permeation agent second liquid containing an oxidant is attached to the hair after finishing the first liquid treatment step;
And a washing step for washing the hair after the second liquid adhesion step.

In the straight perm treatment method of the present invention, as a mounting step, a part of the hair is first separated and mounted on one side of the straight permanent jig according to any one of claims 1 to 5.
Next, as a first liquid treatment step, a hair permanent first liquid containing a reducing agent, an alkaline agent composed of arginine and / or lysine and water is attached and heated with an electric heater. The reducing agent contained in the first liquid for hair permeation agent reduces and cleaves disulfide bonds that crosslink the polyamides constituting the hair. In addition, arginine and lysine contained in the first solution for hair perm is highly basic among the amino acids that constitute proteins (arginine isoelectric point = 10.76, lysine isoelectric point = 9.75), and as an alkaline agent Demonstrate the effect. For this reason, the salt bond which couple | bonds with the acidic amino acid in the polypeptide which comprises hair, and bridge | crosslinks polyamide can be cut | disconnected. Furthermore, even if the polypeptide constituting the hair is hydrolyzed by alkali and damaged, these amino acids regenerate the peptide bond to exert a repair function. In the straight perm treatment method of the present invention, since a highly safe alkaline agent is used as described above, even if the hair is heated with an electric heater to speed up the cleavage of disulfide bonds and the breakage of salt bonds, the alkaline permanent agent can be used. The agent rarely affects hair and skin.

  The reason why the heat treatment with an electric heater or the like is not employed in the treatment of the hair with the conventional first liquid for hair permeation is as follows. That is, when hair is treated with chemicals such as monoethanolamine and isopropanolamine, which have been conventionally used as alkaline agents, the cuticle is easily peeled off and troubles such as rough skin are likely to occur. For this reason, when such a chemical is used as the first liquid for hair perm and heat treatment is performed, there is a risk of serious damage to the hair and skin.

After the heat treatment, as a second liquid treatment step, a hair permanent solution second liquid containing an oxidizing agent such as hydrogen peroxide as a component is attached to the hair that has finished the first liquid treatment step. As a result, the disulfide bond is regenerated and immobilized with the hair straightened. Finally, the hair is washed to wash away the drug, and the straight perm treatment is completed.
Therefore, according to the straight perm treatment method of the present invention, the treatment time is short, the labor amount of the practitioner is small, and the pain given to the practitioner and the practitioner is also reduced.

  The material of the shaping jig body constituting the shaping tool for straight permanents of the present invention is (1) a material having heat resistance that can withstand heating, and (2) a first containing an alkali agent and a reducing agent. It is required that the material has chemical resistance enough to withstand the second agent containing a liquid and an oxidizing agent. As such a material, for example, a thermoplastic resin such as silicon resin, fluorine resin, phenol resin or urea resin, or heat resistant resin such as polycarbonate, polyphenylene ether, polybutylene terephthalate, polyimide, polysulfone, or polyether ketone may be used. it can. In addition, it is also preferable to use a heat insulating material on the side in contact with the hair to protect the scalp and hair from heat. For this reason, it is also preferable to employ a laminate structure in which the hair side is made of a heat insulating material and the side in contact with the permanent liquid is a chemical resistant material. Examples of the heat insulating material include cloth made of glass fiber and corroded cloth.

Hereinafter, embodiments embodying the present invention will be described.
As shown in FIG. 1, the shaping tool for straight permanents of the embodiment includes a shaping tool main body 1 in the form of a long rectangular thin plate made of flexible silicon resin. A rectangular opening 10 is provided at the upper end of the shaping jig main body 1. When the hair is inserted from the back side to the front side, the opening 10 is inserted into the opening upper edge 10 a that comes into contact with the hair from the front side. It has an opening lower edge 10b that comes into contact with the hair from the back side. As shown in FIG. 2, a thin sheet-like resistor 2 made of carbon powder and a binder is sandwiched between the shaping jig main body 1 and the width of one surface side of the resistor 2. Electrodes 3a and 3b made of copper foil are attached to both ends in the direction so as to face each other in parallel and are in electrical contact with the resistor 2. Terminals 4a and 4b connected to the electrodes 3a and 3b are attached to the upper edge of the shaping jig main body 1, and are connected to a power source (not shown) via lead wires 5a and 5b.

Next, a straight perm processing method using the straight perm shaping jig will be described.
<Preparation of Hair Perm Agent First Liquid and Hair Perm Agent Second Liquid>
First, a hair permanent first liquid and a hair permanent second liquid are prepared.
The first liquid for hair permanent contains a reducing agent and an alkaline agent, the alkaline agent is composed of arginine and / or lysine, and other alkalis (for example, aqueous ammonia, monoethanolamine, isopropanolamine, etc.) are substantially. Not included. More preferably, only arginine is used as the alkaline agent. Arginine has a higher isoelectric point than lysine (arginine isoelectric point = 10.76, lysine isoelectric point = 9.75), and can improve alkalinity, so it has excellent ability to break salt bonds and has a wave effect on hair. Can be increased. Moreover, since arginine is superior in chemical stability to lysine, it is possible to store the first liquid for hair permeation for a long period of time. The blending ratio of arginine to water is preferably 0.1 to 15% by mass, more preferably 0.5 to 7% by mass, and most preferably 1 to 3% by mass. When the blending ratio of arginine is less than 0.5% by mass, the pH is lowered and the wave effect is weakened. On the other hand, when the blending ratio of arginine exceeds 15% by mass, not only the production cost increases, but also arginine that cannot be completely dissolved in the winter season is precipitated. Moreover, it is also preferable to manage the blending ratio of arginine by the pH value of the first solution for permanent hair. This is because the pH value is deeply related to the ability of hair to break salt bonds. A preferred pH value is 8 to 10.5, more preferably 8.2 to 10, and most preferably 8.5 to 9.5.

  As a reducing agent, the reducing agent conventionally used for the hair permanent agent 1st liquid can be used. Examples of such a reducing agent include alkali salts of thioglycolic acid such as ammonium thioglycolate and thioglycolic acid monoethanolamine salt, cysteine, cysteine hydrochloride, N-acetylcysteine and the like. As for the density | concentration of a reducing agent, 0.5-15 mass% is preferable with respect to the whole permanent solution 1st hair. More preferably, it is 2 to 10% by weight, and most preferably 3 to 7% by weight. When the concentration of the reducing agent is less than 0.5% by mass, cleavage by reduction of the disulfide bond of hair becomes insufficient, and perm is hardly applied. On the other hand, if the reducing agent exceeds 15% by mass, the reducing power is too strong and the permanent is excessively applied, which may affect the hair and scalp.

  The first liquid for hair permeation includes antioxidants such as sorbic acid and edetate, preservatives such as benzoate and parapenes, viscosity modifiers composed of polymer compounds such as cetanol and propylene glycol, orange oil And other fragrances, emulsifiers, and other auxiliaries can be optionally added.

Hereinafter, a typical method for preparing the first hair permanent solution 1 will be described.
Purified water (100g), polyquaternium-7 (0.085g) methylparapene (0.001g), propylparapene (0.0002g) are put into the stirring vessel of the vacuum emulsifier, heated to 80 ° C, and stirred and mixed under reduced pressure. An aqueous mixture A is obtained.
On the other hand, cetanol (6g), ceteth-40 (1.56g), steartrimonium chloride (1.09g), octyl palmitate (0.96g), paraffin (0.48g), coconut oil fatty acid glyceryl ( 0.48 g), hydrogenated polyisobutene (0.48 g), propylene glycol (0.48 g) and ethanol (0.374 g) are added, heated to 80 ° C., and stirred and mixed under reduced pressure to obtain oil-based mixture B.
Furthermore, the aqueous mixture A and the oil mixture B prepared as described above are put into a stirring vessel of a vacuum emulsifying apparatus, stirred and mixed under reduced pressure, emulsified, and then air-cooled to 40 ° C. to obtain an emulsion. Get. In the emulsion thus obtained, an aqueous solution in which ammonium thioglycolate (5 g) as a reducing agent was dissolved in purified water, an aqueous solution in which an L-arginine aqueous solution (1.5 g) as an alkaline agent was dissolved in purified water, and EDTA- An aqueous solution prepared by dissolving 4Na (0.08 g) in purified water was added in order, and a fragrance (0.2 g) such as orange oil was further added, followed by stirring and mixing. )
In other hair permeation first liquid, it is obtained by appropriately adjusting the mixing ratio of ammonium thioglycolate and L-arginine or L-lysine (other than ammonium thioglycolate, L-arginine and L-lysine). Ingredients are the same as in the above-mentioned hair permanent first liquid).

Table 1 shows the degree of application when the perm of the first liquid for hair permeation prepared by changing the blending ratio of ammonium thioglycolate and L-arginine or L-lysine is performed.

<Preparation of the second permanent solution for hair>
Purified water (100g), polyquaternium-7 (0.085g) methylparapene (0.001g), propylparapene (0.0002g) are put into a stirring vessel of a vacuum emulsifier, heated to 80 ° C, and stirred and mixed under reduced pressure. An aqueous mixture C is obtained.
On the other hand, cetanol (2.25g), ceteth-40 (0.585g), steartrimonium chloride (0.41g), octyl palmitate (0.36g), paraffin (0.18g), coconut oil fatty acid glyceryl in the stirring vessel of the vacuum emulsifier (0.18 g), hydrogenated polyisobutene (0.18 g), propylene glycol (0.18 g), and ethanol (0.14 g) are added, heated to 80 ° C., and stirred and mixed under reduced pressure to obtain an oil-based mixture D.
Further, the water-based mixture C and the oil-based mixture D prepared as described above are put into a stirring vessel of a vacuum emulsifying apparatus, and the mixture emulsified by stirring and mixing under reduced pressure is heated to 80 ° C., and then polyethylene glycol. (1.5 g) and phenacetin (0.05 g) are added and mixed with stirring. Thereafter, the temperature is lowered to 40 ° C. by air cooling, an aqueous solution in which etidronic acid (0.3 g) is dissolved in purified water, an aqueous solution in which disodium phosphate (0.45 g) is dissolved in purified water, and about 30% hydrogen peroxide solution An aqueous solution obtained by dissolving (0.15 g) in purified water is added in order, and a fragrance (0.05 g) such as orange oil is further added, followed by stirring and mixing to obtain a second liquid for permanent hair.

<Installation process>
Cut and wash the subject's hair as necessary and dry. Thereafter, as a pretreatment, a liquid containing treatment components such as keratin and hyaluronic acid is applied to the hair and left for several minutes to 10 minutes. And
A part of the hair is separated, and as shown in FIGS. 3 and 4, the separated hair is inserted from the inside to the outside of the opening 10 of the shaping tool for straight permanents, and the hair is fastened from the periphery of the opening 10. The hair is fastened with 6a, 6b, 6c and 6d. Since the hair inserted through the opening 10 is brought into contact with and caught by the upper edge 10a and the lower edge 10b of the opening, it is combined with the locking effect of the hair clasps 6a, 6b, 6c, and 6d. The shaping jig is reliably prevented from falling off. In addition, when curling a hair tip, as shown in FIG. 5, the lower end of the shaping jig main body 1 may be rounded in the direction of curling with the hair and fastened with a hairpin 7 or the like.

<First liquid treatment process>
Next, the first liquid for the permanent agent for hair is evenly attached to the hair attached to the shaping tool for straight permanent using the dropper as described above. Then, the power switch is turned on, the resistor 2 (FIGS. 1 and 2) is heated, and the hair is warmed for about 5 minutes. This heating step promotes the breakage of the salt bond by the alkaline agent contained in the first liquid of the hair permanent agent and the breakage of the disulfide bond by the reducing agent, so that the hair is straightened. Since the silicon resin constituting the shaping jig body 1 is excellent in heat resistance and alkali resistance, it is not altered by heating.

<Second liquid treatment process>
After completion of the first liquid treatment step, the first liquid for the hair permanent is uniformly attached to the hair using a dropper. As a result, the disulfide bond is regenerated and immobilized with the hair straightened.
<Washing process>
Finally, the hair is washed to wash away the drug, and the straight perm treatment is completed.

In the shaping tool for straight permanents of the embodiment, the shaping jig body 1 is provided with the resistor 2, so that the salt bond cleavage reaction and the disulfide bond cleavage reaction by the hair permanent agent first liquid are heated. Since it can be carried out, the reaction is accelerated and the treatment can be carried out very quickly. In addition, since there is no particular work for the practitioner during the heating process, the labor load of the practitioner is small. Moreover, since the alkaline agent contained in the first liquid for hair perm uses arginine and lysine, which are amino acids that constitute the human body, chemical substances such as ammonia and hydroxy organic amines are used as alkaline agents. Compared with the conventional 1st liquid perm agent for hair, the influence on hair and skin is extremely small.
Therefore, according to this straight perm treatment method, the treatment time is short, the labor amount of the practitioner is small, and the pain given to the practitioner and the practitioner is reduced.

In the above embodiment, the opening does not have a notch, but instead of this, an opening having a notch may be used as shown in FIGS. In this case, the hair can be easily inserted into the opening by inserting the hair from the notch. In the example shown in FIG. 6a, the notch is provided in the approximate center of the upper edge of the shaping jig body. Thereby, the electric heater power supply line can be embedded in a straight line from the terminal on both sides of the opening. In the example shown in FIG. 6b, the notch has a large diameter. This facilitates the insertion of the hair. In the example shown in FIG. 6c, the notch is provided on the side edge of the shaping jig body. Thereby, the upper edge of the opening part which contacts hair becomes long, and the attachment of the shaping jig with respect to hair is stabilized. In the example shown in FIG. 6d, the diameter of the notch is increased compared to the example of FIG. 6c, so that the hair can be easily inserted.
In addition, a control IC circuit having a voltage adjustment function, a timer function, a temperature adjustment function, etc. is embedded in the shaping jig body of the straight permanent shaping tool of the embodiment, thereby performing temperature control, time control, etc. You can also.

  The present invention is not limited to the description of the embodiments and examples of the invention described above. Various modifications are also included in the present invention as long as those skilled in the art can easily conceive without departing from the scope of the claims.
