[0001] HAIR REDUCING AGENT USED FOR PERMANENT WAVE AND METHOD FOR PERMING HAIR USING THE SAME [0002]

The present invention relates to a hair perming agent used in hair permer treatment and a method of perming hair using the same.

As the quality of life of modern people has increased, people have become increasingly interested in cosmetology, and procedures for shaping the shape of hair into straight or wave shapes have become routinely popular among the public.

Thus, in recent years, many people have undergone permanent surgery, but this has been observed to severely damage keratin fibers in the hair.

In general, hair perming treatment is performed by applying a first preparation combined with a reducing agent that reduces the cystine bond in the hair to a desired shape, and then forming an oxidizing agent for oxidizing the cystine bond to maintain the shape of the formed hair And then applying the second material blended to the hair.

At this time, salts and esters of thioglycolic acid are mainly used as the reducing agent included in the first preparation, and cysteine, cysteamine, thiolactic acid and derivatives thereof are also frequently used. However, thioglycolic acid is excellent in the action of forming hair, but it has a high degree of damage to the hair due to strong action on the hair, and the degree of molding of the hair ends and hair roots is different. A phenomenon appears.

In addition, the oxidizing agent contained in the second preparation is generally composed of bromate as a main component and hydrogen peroxide as a main component. The bromate has less stimulation to the hair than the hydrogen peroxide, but the treatment time is prolonged and the hair is exposed to the drug for a long time And eventually the hair tends to be damaged. On the other hand, hydrogen peroxide has a strong oxidizing action and can shorten the treatment time, but has a disadvantage that the irritation to the hair is strong and the degree of damage is large and the treatment is likely to be uneven.

Conventional hair treatment agents used for shaping hair as described above have various side effects such as damage to scalp and hair due to various chemical components, hair loss, atopy, respiratory or skin contact allergies due to odor, and the like.

The monoglycerol esters of thioglycolic acid proposed in Japanese Patent Application Laid-Open No. H08-291031 are excellent in handleability and have a specific odor, and since there is a report on the sensitization which is presumed to be caused by the hydroxyl group in the structure, There is no.

It is already known that the mercaptocarboxylic acid amide proposed in Japanese Patent Laid-Open No. 2000-507272 causes skin irritation. In addition, the mercaptocarboxylic acid amide derivative proposed in Japanese Patent Application Laid-Open No. 2003-528901 may have a similar feeling of sensitivity, and may cause insufficient purification or sensitization caused by amines, which are liberated during preservation, There is concern about irritability.

The cysteamine proposed in Japanese Patent Application Laid-Open No. Hei 03-271214 has many problems such as insufficient permerability under a slightly acidic to acidic condition and a peculiar odor from a hair subjected to permanent surgery.

As described above, the keratin reducing materials proposed so far can not provide a desired hair treatment agent.

When such conventional hair treatment agents are used at a pH in the neutral to slightly acidic range, they do not always exhibit satisfactory permanent performance in this range. Excessive use to ensure permanent performance can lead to other problems such as persistent smell and damage to the scalp by the reducing material.

In addition, since the mercapto compound, which is a reducing agent of hair treating agents, has chemically reactivity with water, when it is left for a long time or stored, there is a problem that the reducing power of the reducing agent is reduced and the wave efficiency is lowered and the reproducibility of permanent performance is remarkably deteriorated. Thus, there was no hair treating agent having the desired permanent performance.

In order to solve the above problems, the present applicant provides a hair permer reducing agent containing a cyclic mercapto compound as a keratin reducing substance according to the present invention. However, when the hair treating agent contains water, the cyclic mercapto compound is hydrolyzed, and the concentration of the cyclic mercapto compound in the treating agent decreases with time and decomposes, thereby causing discoloration and precipitation, thereby damaging the appearance.

Therefore, it is an object of the present invention to provide a hair remover which can have a safe performance and a good appearance for a long time by preventing the reduction of the concentration of the cyclic mercapto compound and the coloring and sedimentation of the hair treatment agent over time, when the cyclic mercapto compound is present in water, It is an object of the present invention to provide a reducing agent.

When the permanent waving hair is subjected to the conventional permanent waving treatment, a first preparation containing a reducing agent (hereinafter also referred to as a permanent waving first preparation) and a second preparation containing an oxidizing agent (hereinafter also referred to as a permanent waving second preparation) Use a formulation. As described in the above Patent Documents, the reducing agent in the first preparation contains a mercapto compound as a main component, so that the permanent waving treatment involves an unpleasant smell.

Accordingly, another object of the present invention is to provide a hair permer reducing agent capable of perming permanent wave hair and blocking unpleasant odors even in the range of neutral to slightly acidic pH causing less skin irritation.

The present inventors have intensively studied and found that the use of a specific cyclic mercapto compound as a keratin reducing substance in the permanent waving first preparation can have a higher perming performance in the range of neutral to slightly acidic pH than known compounds.

Further, it has been found that the cyclic mercapto compound has a higher perming performance in the range of neutral to slightly acidic pH than the known compound. As a result of further studies, it has been found that when a cyclic mercapto compound is used in combination with other keratin reducing materials, Lt; RTI ID = 0.0 > perms. ≪ / RTI >

In addition, it has been found that a hair treatment agent containing a surfactant in place of a specific cyclic mercapto compound, water, exhibits improved stability of the cyclic mercapto compound in the treatment agent.

Further, when a cyclic mercapto compound is used in combination with a specific perfume as the keratin reducing material, a hair treatment agent having a higher perming performance in a pH range of neutral to weakly acidic than a known compound and having an unpleasant odor caused by a mercapto group is blocked .

The present invention is based on this finding.

It is an object of the present invention to solve the above-mentioned problems and to provide a hair conditioner which effectively removes and decomposes all substances capable of causing basic pH to minimize the dissolution and denaturation of proteins in hair, Provides a hair permer reducing agent that can provide excellent curl in the environment and permits perming for damaged hair.

When the content of 2-mercapto-4-butylolactone is less than 23% by weight, the reducing power may decrease and the wave efficiency of the hair may be lowered. On the other hand, when the content of (b) May damage hair.

In addition, the hair-perming reducing agent does not contain water, thereby preventing hydrolysis of 2-mercapto-4-butyrolactone due to chemical reaction to water, and does not cause layer separation during storage for a long period of time. Accordingly, it is possible to prevent the loss of reducing power of the hair permer reducing agent of the present invention and to have an effect of being able to be stored for a long period of time.

In addition, since the hair perisher reducing agent includes (a) in place of water, the soft hair texture and elasticity of the hair can be obtained after the permanent hair treatment, and a permanent having the same curl shape can be realized .

Thus, It is possible to protect the hair, to have wetting and moisturizing effect, as well as to reduce the degree of damage which may be caused by the perming procedure.

In addition, since the pH of the hair perisher reducing agent is weakly acidic, the pH of the hair permer reducing agent is 5.8 to 6.2, so that when the hair permer is applied using the hair permer reducing agent, hair damage can be remarkably reduced compared to the conventional alkaline hair permanent reducing agent.

In addition, the hair permer reducing agent may further add fragrance as necessary to further prevent unpleasant odors and to provide various fragrances.

The hair permer reducing agent provided by the present invention does not cause an unpleasant smell by including all the ingredients in a specific ratio and content as described above, and maintains the reducing power of the hair permanent reducing agent even when stored for a long period of time, It is possible to secure an effect that enables the user.

According to another embodiment of the present invention, there is provided a method of perming hair using a hair permer reducing agent provided in the present invention, comprising the steps of: (A-1) determining the degree of hair damage by checking the degree of damage of the hair of the subject; (A-2) preparing a mixed solution using at least one of a solvent and a perming reagent; (A-3) applying a mixed solution to a part of the hair; (A-4) heating the hair after molding; (A-5) applying an oxidizing agent to the hair; And (A-6) washing the hair and drying the hair.

The hair perming reducing agent used in the perming method of the present invention is the same as that described above as provided in the present invention as described above.

However, in the permanent method of the present invention, it is not necessary to use the hair remover of the present invention as it is, but it is also possible to determine the degree of damage of the hair of the client before the permanent operation and to treat at least one of the solvent, And then applied to at least a portion of the hair desired for permanent operation.

Further, in the permanent method of the present invention, the solvent in the step (A-2) is preferably selected from the group consisting of water, a water-soluble treatment agent and a combination thereof, but is not particularly limited as long as it does not damage hair .

Here, in the step (A-2), the blending ratio of the hair perisher reducing agent and at least one of the solvent and the perming reagent is 1:10 to 1:40, which may vary depending on the hair condition of the existing physician.

In step (A-1) of the perming method of the present invention, the degree of damage of the existing patient's hair can be divided into 1 to 3 stages. The second stage is the middle to upper thigh; And the third step can be classified into the pole damage.

In the step (A-2), the hair perisher reducing agent provided by the present invention may be prepared and used differently according to the degree of damage of each existing facial hair in step (A-3).

If the pH of the mixed solution prepared in step (A-2) may be 4 to 9.2, and if it is the first step in step (A-1) according to the degree of damage of the existing patient's hair, The pH of the mixed solution prepared in step (A-2) may be from 4 to 5.4, and the pH of the mixed solution prepared in step (A-2) may be from 8.5 to 9.2. , And in the case of the third step in the step (A-1), the pH of the mixed solution prepared in the step (A-2) may be 4 to 5.4.

As described above, the mixed solution prepared in the step (A-2) is manufactured in consideration of the health condition of the hair of the existing physician, so that a superior permanent can be realized without damaging the hair

In addition, since the mixed solution prepared in the step (A-3) for forming a wave on the damaged or severely damaged hair is weakly acidic, the pH of which is 4 to 5.4, when the hair is pumped using the hair, the conventional alkaline hair permer reducing agent The damage of the contrast hair is remarkably reduced, and a wave can be formed on damaged hair which can not be conventionally attempted.

Next, a part of the mixed solution prepared in the step (A-2) is applied to the hair desired to perform the permanent operation in the step (A-3), the hair is formed in the step (A-4) .

At this time, the shape and method of shaping the hair can be performed by the person skilled in the art in a desired shape or shape, and is not particularly limited as long as it can be molded into various shapes by a method generally used in the art. For example, a rod may be used to wind all or a portion of a hair to form a wave, or a hair or a hair iron may be used to perform a straightening by pressing all or a part of the hair.

In step (A-4), all or part of the hair is heated at 50 to 55 ° C for 8 to 10 minutes, and then left to stand for 8 to 10 minutes at room temperature (A-4a) Step < / RTI >

Next, the shape and shape of the hair formed by applying the oxidizing agent to the hair heated after the molding in the step (A-5) can be maintained. In the step (A-6), the hair is washed and dried The hair perisher reducing agent and the oxidizing agent applied to the hair can be removed from the hair.

In the step (A-5), the oxidizing agent may be used without limitation as long as it is an oxidizing agent generally used in the art, and the amount thereof may be appropriately used depending on the amount of the hair permer reducing agent and the degree of damage of the hair of the subject. .

In addition, it is possible to carry out the step of applying the oxidizing agent to the hair in the step (A-5), and then allowing the hair to stand at room temperature for 5 to 10 minutes.

Here, the oxidizing agent preferably includes hydrogen peroxide or bromate, and is not particularly limited as long as it is an oxidizing agent that can be easily used in the art.

The type and amount of the shampoo which can be used for washing the hair in the step (A-6) can be used without limitation as long as it is a shampoo commonly used in the related art, and the amount thereof can be appropriately selected depending on the thickness and amount of the hair Can be used.

After the completion of the hair washing, the hair may be dried. At this time, the hair may be dried by using a towel to remove moisture or drying the hair. In one embodiment, a step of drying the hair using a dryer for 5 to 10 minutes may be performed.

Therefore, the perming method of the present invention makes it possible to make excellent permanent without damaging the hair by preparing the mixed solution considering the condition of the hair of the subject before the perming procedure, and to form an excellent wave regardless of the condition of the existing patient's hair But it can exhibit the effect of having excellent performance together with the texture of the soft hair and the texture of the hair.
