Description

  The present invention relates to a hair treatment agent and a hair treatment method using the hair treatment agent, and more particularly to a hair treatment agent using an egg white hydrolyzate and a hair treatment method using the hair treatment agent.

  In recent years, an increasing number of people have damaged hair due to repeated use such as coloring (bleaching), permanent wave, and straight (hair straightening) treatment. Hair damage is caused by a combination of physical damage including brushing and dryer heat, chemical damage due to coloring, bleach, permanent wave, straight treatment, etc., and environmental damage due to sunlight, seawater, etc. Occur. Among them, the bleaching treatment of hair is a method of decomposing melanin pigment existing in hair with an oxidizing agent such as hydrogen peroxide water, and at this time, cleavage of -SS- bond existing in hair occurs, Damage will occur. It is known that hair that has been subjected to bleach treatment several times has a significantly reduced -SS- content compared to untreated hair (Non-patent Document 1).

  The -SS- bond in hair forms a three-dimensional cross-link in hair and not only greatly contributes to physicochemical characteristics or its structural stability, but also to permanent wave and shrinkage of hair. It also plays an important role in hair straightening treatment. In other words, the permanent wave treatment of hair skillfully utilizes -SS- bond cleavage (reduction process) and recombination (oxidation process) present in hair, and is widely used in the beauty industry. For many years, thioglycolic acid (TG), L-cysteine (CYS), etc. have been used as reducing agents in the reduction process, and these reducing agents have a function (set performance) by penetrating and diffusing into the hair. It is expressed (Non-patent Document 2). Functionality in such permanent wave and curly hair straightening treatment (such as the wave forming ability of hair, particularly the wave retention rate) greatly affects the -SS- content in the hair. When permanent wave treatment is performed on hair (high-damaged hair) having a significantly reduced -SS- content due to the bleaching treatment described above, there is a problem that desired wave formation cannot be obtained. In addition, when such a highly damaged hair is subjected to a straight treatment, not only the desired straight formation cannot be obtained, but also the hair shape is changed due to protein denaturation, causing damage.

  Furthermore, when the —SS— bond present in the hair is cleaved by the reducing agent, the interaction of proteins in the hair is significantly reduced. That is, depending on the type of reducing agent used, there is a problem that the hair tensile cutting strength after the reduction / oxidation treatment is remarkably lowered.

  In addition, for the purpose of improving the effect of repairing hair damage, a hair cosmetic characterized in that the hair cosmetic contains a protein hydrolyzate derived from keratin, collagen, silk, elastin and egg white has been proposed. Yes. For example, in Patent Document 1, egg white is hydrolyzed using papain, egg white is hydrolyzed using papain, and the resulting reaction solution is heated to 65 to 75 ° C., followed by trypsin and Bacillus bacteria An egg white hydrolyzate obtained by hydrolyzing with at least one protein hydrolase selected from the group consisting of protease, Aspergillus filamentous fungus-derived protease and bromelain, and further with peptidase Has been proposed. In Patent Document 1, a hair cosmetic containing the above egg white hydrolyzate is applied, left at 27 ° C. for 10 minutes (twice the bath ratio), then dried using a hair dryer, and this operation is repeated. It is described that the effect of improving the elasticity, texture, and gloss of hair and the effect of repairing hair damage can be obtained.

  However, in any non-patent literature and patent literature, the wave forming power and straight formation can be obtained by using the hair as a permanent wave and hair straightening treatment before and after hair straightening and applying to hair. There is no description that the force and the tensile cutting strength of the hair are improved. Further, there is no description that desired wave formation or straight formation can be obtained even with damaged hair (high damage hair) having a low -SS- content.

  In a preferred embodiment of the hair treatment method of the present invention, the egg white is a dried egg white of chicken eggs.

  According to the hair treatment agent and hair treatment method of the present invention, it is advantageous that desired wave formation and straight formation can be obtained without causing damage to even damaged hair (high damage hair) having a low -SS- content. There is an effect.

  According to the hair treatment method of the present invention, in the permanent wave treatment and the straight (hair straightening) treatment step, at least one cosmetic in the pretreatment agent, the permanent wave first agent, the intermediate treatment agent, and the permanent wave second agent. In which the wave forming power, straight forming power, and tensile cutting strength of hair are improved by adding egg white hydrolyzate to a chemically acceptable medium and treating the hair with the composition. There is an advantageous effect that a processing method can be provided.

  The hair treatment agent of the present invention contains egg white hydrolyzate and alkaline ionized water.

  In a preferred embodiment of the hair treatment agent of the present invention, the hair treatment agent is a permanent wave treatment agent or a hair straightening treatment agent. By using these treatment agents, it is possible to improve the wave forming force and straight forming force, and on the other hand, strengthen the hair.

  In a preferred embodiment of the hair treatment agent of the present invention, alkaline ionized water has a pH of 9 or more from the viewpoint of cleaving ionic bonds existing in the hair and promoting the permeability of active ingredients such as egg white hydrolysates. Preferably, it consists of pH 10 or more. The alkali ion water is not particularly limited as long as it is water showing alkalinity. For example, alkali ion water can be made from an alkali ion water conditioner (also called an alkali ion generator), and can be said to be one of electrolyzed water. Alkaline ion water shows its effect due to the nature of alkalinity, and pH is an index of all, and all is controlled by pH. As a result, hydroxides contained in tap water, such as hydroxides of alkali metals such as calcium hydroxide, are considered to be the essence. There are also scholars who classify alkaline ionized water with a negative reduction potential of −200 mV or more as active hydrogen water. For example, reduced water is based on an electrolysis method that considers the effect of reducing nature, and a case where three properties of “pH + redox + electron” are managed by a method of giving a property that gives electrons. Is also included. The reducibility is exactly the amount of electrons, and the reductivity of water with a large amount of electrons is high.

Furthermore, pH 11 or higher is called strong electrolytic alkaline water, and pH 13.1 is currently the strongest. Strong alkaline ionized water is physically electron-excess water obtained by treating natural water by electrolysis and energizing / pressurizing a special diaphragm device. Examples of the reduced water include S-100 (trade name, manufactured by AI System Product Co., Ltd.). In addition, as an MSDS sheet of S-100 (trade name, manufactured by AI System Product Co., Ltd.), for example, a mixture (electrolytically reduced ion water), components (H ₂ O, SiO ₂ , Na ₂ O, Cl) , CaO, K, P, Mg), content 0.3% (H ₂ O: 99.7%), raw material name electrolytic reducing ionized water S-100, specific gravity 1.001 (20 ° C.), hydrogen ion concentration Some components have a pH of 12 ± 0.5 and a redox potential of 0 to −100 mV.

  Examples of the method for producing alkaline ionized water include electrolysis using an ion exchange membrane as a salt bridge and separating electrodes. When a voltage is applied to the aqueous solution using an electrode, the anion is oxidized at the anode and the cation is reduced at the cathode. Various ions are dissolved in the tap water, and which ions are oxidized and reduced depends on the redox potential (reduction potential) of the dissolved ions and the concentration of the ions. Therefore, the composition of the final product depends on the components of the original tap water. Generally, hydrogen is generated at the anode and the solution becomes alkaline. The alkaline ionized water that can be used in the present invention includes those described above.

  Strong alkaline ionized water is physically electron-excess water obtained by treating natural water by electrolysis and energizing / pressurizing a special diaphragm device. For example, strong alkaline ionized water may be super-reducing water, from the viewpoint of more effectively promoting the permeability of active ingredients such as egg white hydrolyzate by cleaving ionic bonds present in hair. Examples of the strong alkaline ionized water include electrolytic water having a hydrogen ion concentration of pH 11 or more, an oxidation-reduction potential of 0 mV or less, and an osmotic pressure of 100 (mOsM) or less. Examples of the super-reduced water include S-100 (trade name, manufactured by AI System Product Co., Ltd.).

  Next, the hair treatment method of the present invention will be described. The hair treatment method of the present invention is the hair treatment method of the present invention in which at least one of a pretreatment agent, a first agent containing at least a reducing agent, an intermediate treatment agent, a second agent containing at least an oxidizing agent, and a posttreatment agent. It is characterized by treating hair with a composition in which the above-mentioned hair treatment agent of the present invention is added in one cosmetically acceptable treatment medium. From the viewpoint of extracting the effect, the patient may be treated with the pretreatment agent or the like to which the hair treatment agent of the present invention has been added and dried, and then subjected to the next treatment.

  In the present invention, a composition in which the above-described hair treatment agent of the present invention is added to at least one cosmetically acceptable treatment medium of a pretreatment agent, a first agent, an intermediate treatment agent, a second agent, and a posttreatment agent. The reason for using the product is as follows.

  In other words, when permanent wave treatment is applied to hair (high-damaged hair) with a significantly reduced -SS- content, there is a problem that the desired wave formation cannot be obtained, and good permanent wave treatment and curly hair straightening treatment. Because there was a background that some kind of treatment is necessary to perform, pre-, intermediate and post-treatment agents in permanent wave treatment and hair straightening treatment are very important, such as keratin and collagen before and after treatment This is because we developed a product that can achieve the function of a permanent wave agent, such as using a protein hydrolyzate to suppress the progression of hair structure deterioration during treatment and reinforcing the damaged part. is there.

  The role of the pre-, intermediate-, and post-treatment agents is to make the permanent wave agent selected according to the condition and purpose of the hair (creating the desired hair style) act on the hair as uniformly and efficiently as possible, while maintaining the elasticity of the hair. It is to promote oxidation fixation by treatment with the second agent and to protect the hair from further damage.

  First, the pre-treatment agent is used before permanent wave treatment and hair straightening treatment, and it acts on particularly damaged parts to reinforce and protect the inside of the hair and the surface of the hair, and suppress the penetration of the permanent wave first agent. It is a treatment agent intended to prevent uniform wave formation and hair damage. On the other hand, it is intended to promote the penetration of the reducing agent, which is an active ingredient of the permanent wave first agent, for hair that is difficult to act on the permanent wave agent such as water repellent hair and hard hair. Typical components include PPT (protein hydrolyzate), humectant, oil agent, polymer compound, surfactant and the like.

  The first agent is a permanent wave (hair straightening) first agent containing at least a reducing agent, and the second agent is a permanent wave (hair straightening) containing at least an oxidizing agent. It is the second agent.

  The permanent wave (hair straightening) treatment agent is generally composed of a permanent wave first agent and a permanent wave second agent. In addition to the reducing agent, the active ingredient blended with the permanent wave first agent swells the hair by adjusting the pH to alkali and contributes to the penetration of the active ingredient into the hair and reduces the reducing agent's reducing power. Alkaline agent for enhancing, conditioning agent for protecting from permanent wave damage and maintaining the state after permanent wave, hair protectant, fragrance for masking odor of alkaline agent, etc., reducing agent It can contain a reaction modifier that suppresses overreaction, an anti-inflammatory agent that relieves irritation to the scalp, a metal sequestering agent, a surfactant, and the like.

  On the other hand, the active ingredient blended in the permanent wave second agent is an oxidizing agent for recombining the cleaved -SS-bond, and in addition, a pH adjusting agent, a conditioning agent, a metal sequestering agent, , A surfactant and the like can be contained.

  And the following can be mentioned as a processing agent applicable to the hair processing agent of this invention. For example, the permanent wave preparation as a quasi-drug has the following nine types depending on the active ingredient, efficacy, effect, and usage, that is, a cold bath type permanent wave preparation containing thioglycolic acid or a salt thereof as an active ingredient, cysteine Cold-bath permanent wave agent containing galactose salts or acetylcysteine as an active ingredient, Warm-bath-type permanent wave agent containing thioglycolic acid or its salt as an active ingredient, Warming containing cysteine salts or acetylcysteine as an active ingredient Two-bath permanent wave agent, cold one-bath permanent wave agent containing thioglycolic acid or its salt as an active ingredient, and permanent wave first agent containing thioglycolic acid or its salt as an active ingredient Wave agent, thioglyco Cold-bath-type hair straightener containing phosphoric acid or its salts as an active ingredient, heated two-bath hair straightener containing thioglycolic acid or its salts as an active ingredient, thioglycolic acid or its salts as an active ingredient at high temperature Examples thereof include a heated two-bath type hair straightener using a hairstyling iron.

  Cold-bath permanent wave agent containing thioglycolic acid or its salts as the active ingredient is the permanent wave second, which cleaves the -SS- bond of hair with thioglycolic acid and alkali contained in permanent wave first agent. The -SS- bond is recombined with bromate or hydrogen peroxide added to the agent. The permanent wave first agent may contain up to 4% of a dithiodiglycolic acid, which is a reaction regulator that suppresses excessive reaction of thioglycolic acid.

  A cold bath-based permanent wave agent containing cysteine salts or acetyl cysteine as an active ingredient is the permanent wave first, which breaks the -SS- bond of hair with cysteine or acetyl cysteine and alkali contained in the first permanent wave agent. The -SS- bond is recombined with bromate or hydrogen peroxide blended in the two agents. The permanent wave first agent can contain up to 1% thioglycolic acid as a stabilizer (antioxidant).

  What is a heated two-bath type permanent wave agent containing thioglycolic acid or a salt thereof as an active ingredient? An active ingredient blended in the drug is the above-mentioned cold two-bath type permanent wave agent containing thioglycolic acid or a salt thereof as an active ingredient However, heating at 60 ° C. or lower is recognized during processing. Since the reaction is promoted by heating, the upper limits of the thioglycolic acid concentration, alkali, and pH of the permanent wave first agent are set lower than the above 1.

  What is a heated two-bath type permanent wave agent containing cysteine salts or acetylcysteine as an active ingredient? The active ingredient added to the agent is the above-mentioned cold-bath type permanent wave agent containing cysteine salts or acetylcysteine as an active ingredient However, heating at 60 ° C. or lower is recognized during processing. Since the reaction is promoted by heating, the upper limit of the cysteine concentration and alkali of the permanent wave first agent is set lower than that of the cold bath type permanent wave agent containing thioglycolic acid or a salt thereof as an active ingredient.

  A cold one-bath type permanent wave agent containing thioglycolic acid or its salt as an active ingredient is a permanent solution containing only the first thio-type permanent wave agent, and the permanent wave second agent treatment is performed by air oxidation. is there. Therefore, the range of thio concentration, pH, and alkali of the permanent wave first agent is narrow and the upper limit is set low. Since there is no need for the permanent wave second agent treatment, the treatment time is short, but the burden on the hair is not small.

  Prepared at the time of the first permanent wave agent containing thioglycolic acid or its salt as an active ingredient The exothermic two-bath type permanent wave agent is a mixture of two types of permanent wave first agent immediately before use and applied to the hair. It is the type to do. The thioglycolic acid contained in one of them and the hydrogen peroxide contained in the other undergo an oxidation-reduction reaction, generating heat and raising the liquid temperature to about 40 ° C. Since excess thioglycolic acid is added to hydrogen peroxide, thioglycolic acid and heat will remain after mixing, and this heat will increase the reactivity of thioglycolic acid and have a strong effect on hair . The second permanent wave agent is the same as the cold bath type permanent wave agent containing thioglycolic acid or a salt thereof as an active ingredient.

  Coldni bath hair straighteners containing thioglycolic acid or its salts as the active ingredient are the same as the standard values for Permanent Wave 1st Agent and Permanent Wave 2nd Agent, and the reaction mechanism is the same as in 1 above. This type is used for the opposite purpose in terms of extending hair. For the purpose of extending eyelashes, many are creamy.

  The heated two-bath hair straightener containing thioglycolic acid or its salt as an active ingredient is the standard value of permanent wave first agent and permanent wave second agent, and the reaction mechanism is the above-mentioned thioglycolic acid or salt thereof. It is the same as the heated two-bath type permanent wave agent as an active ingredient, but is used for the opposite purpose in terms of extending waves and curly hair. For the purpose of extending eyelashes, many are creamy.

  The warming two-bath hair straightener that uses thioglycolic acid or its salts as an active ingredient and a high-temperature hair-styling iron is the standard value of the permanent wave first agent and the permanent wave second agent, and the reaction mechanism of the chemical is thio It is the same as the heated two-bath type permanent wave agent containing glycolic acid or its salt as an active ingredient, but further uses the above-mentioned thioglycolic acid or its salt as an active ingredient in terms of using cold iron bath type curly hair straightening. It is of a different type from a hair straightening agent such as a heated two-bath type hair straightening agent comprising an agent, thioglycolic acid or a salt thereof as an active ingredient. The present invention can also be applied to such known treatment agents.

  In addition, the hair treatment agent of this invention is a treatment agent applicable also to cosmetic curling charges. That is, in recent years, curling charges containing cysteamine hydrochloride, butyrolactone thiol, thioglycerin, thiouric acid, sodium sulfite, and glyceryl monothioglycolate reducing agents have been marketed as washable set charges due to the deregulation of permanent wave standards. However, the hair treatment agent of the present invention can be applied as a treatment agent for these cosmetic curling materials.

  The intermediate treatment agent is used after the intermediate water treatment after the permanent wave first agent treatment. The treatment agent mainly neutralizes one agent alkali and returns the hair pH to the isoelectric point. It is. In addition, after the permanent wave first agent treatment, the hair is in the most swollen state and the object is to replenish PPT and the like. By these, the oxidative fixation of the permanent wave second agent can be promoted, the hair can be reinforced, and the original elasticity can be given. Typical components include PPT (protein hydrolyzate), pH adjuster, humectant, surfactant and the like.

  The post-treatment agent is used after washing with water after the permanent wave second agent treatment, and the hair condition associated with the permanent wave treatment is adjusted, and residual alkali is neutralized and removed to enhance the oxidation treatment. Or a treatment agent for the purpose of protecting the hair so as not to damage the hair. Typical components include PPT (protein hydrolyzate), humectant, oil agent, polymer compound, pH adjuster, surfactant and the like.

  In a preferred embodiment of the hair treatment method of the present invention, the hair treatment is a permanent wave treatment or a straight (hair straightening) treatment. In addition, as a feature of the processing method of the egg white hydrolyzate in the present invention, it is considered that the effect is higher when the curly hair straightening process using a high-temperature hairstyling iron is performed in the intermediate processing step of the egg white hydrolyzate. ing.

  EXAMPLES Next, although this invention is demonstrated in detail based on an Example, this invention is not intended to be limited only to this Example.

Example 1 and Comparative Examples 1-3
The protein shown in Table 1 is diluted with alkaline ionized water [Released from: Sunny Place Co., Ltd., trade name: Platinum Amino Ionized Water] so as to have the concentration shown in Table 1. Intermediate treatment (hair treatment according to the present invention) Agent) was prepared.

  Using the hair treated with various intermediate treatment agents during the permanent wave treatment, the wave efficiency by the Kilby method and the hair tensile cutting strength test were conducted. The evaluation method is shown below.

Evaluation Test A [Wave Efficiency Test by Kilby Method]
The wave efficiency was measured according to the Kilby method (Non-Patent Document 2). A bundle of 20 healthy human hairs (length: 20 cm) having the same cuticle orientation was immersed in a 0.5 wt% sodium lauryl sulfate solution at 50 ° C. for 10 minutes. The hair sample was then prepared by washing with running water and drying. The hair bundled on one side with a wave efficiency measuring instrument was fixed with a rubber band, and the other end was alternately passed through the shaft without being loosened and pulled strongly, and fixed with the rubber band to the instrument. The hair-fixed device was pretreated in platinum amino ion water (pH 11.5) at 25 ° C. for 15 minutes (250 times the bath ratio), and then the permanent wave first agent [release source: (stock) ) Sunny Place, trade name: Ion cis (super hard type)] at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Next, after immersing in each of the intermediate treatment agents obtained above at 25 ° C. for 15 minutes (bath ratio 250 times), permanent wave second agent [Sunny Place Co., Ltd., trade name: Ion cis (super hard type) ] Was immersed for 15 minutes at 25 ° C (bath ratio 250 times) and washed with water. Remove the sample from the instrument and place it gently on the glass plate. Measure the length (b) of the first to fifth curls and calculate the wave efficiency using the following formula (1). did. For comparison, the wave efficiency was also calculated when intermediate processing was excluded.

Here, a: length from the first to the fifth of the stopper rod (mm), b: length of the curl vertex from the first to the fifth (mm), c: length when b is a straight line (Mm).

Wave efficiency (%) = 100 [1-{(ba) / (ca)}] (1)

Evaluation test B [Hair tensile cutting strength test]
After performing a wave efficiency test by the Kilby method, the hair per hair was dried at room temperature using a high-sensitivity hair tension tester (KES-G1-SH, manufactured by Kato Tech Co., Ltd.). The cutting strength was measured at a tensile speed of 1.2 cm / min (n = 10).

  Table 1 shows the wave efficiency, tensile cutting strength, etc. when various proteins are used.

  In Table 1, the comparative keratin hydrolyzate refers to the trade name: Promois WK-H (manufactured by Seiwa Kasei Co., Ltd.), and the pea protein hydrolyzate refers to the trade name: Promois WJ (manufactured by Seiwa Kasei Co., Ltd.). .

  From Table 1, using the egg white hydrolyzate-containing composition, the wave efficiency is remarkably improved as compared with the case where the intermediate treatment was carried out (Example 1) and the case where the intermediate treatment was not carried out (Comparative Example 1). It can be seen that the tensile cut strength (significant difference test between Example 1 and Comparative Example 1: P <0.05) is improved with a significant difference. On the other hand, when an intermediate treatment is performed using a keratin hydrolyzate (Comparative Example 2), the wave efficiency is slightly improved, but the tensile strength is not improved at all. Moreover, when an intermediate process is implemented using a pea protein hydrolyzate (comparative example 3), although wave efficiency improves, on the other hand, it turns out that tensile cutting strength falls a little.

Examples 2 to 4 and Comparative Example 2
The pretreatment agent was prepared by diluting the proteins shown in Table 2 with alkaline ionized water [sales source: Sunny Place, Inc., trade name: platinum amino ion water] so as to have the concentration shown in Table 2.

Using the hair that was treated with the pretreatment agent during the permanent wave treatment, the wave efficiency by the Kilby method and the hair tensile cutting strength test were conducted. The evaluation method is shown below.

Evaluation test C [Wave efficiency test by Kilby method]
The wave efficiency was measured according to the Kilby method (Non-Patent Document 2). A bundle of 20 healthy human hairs (length: 20 cm) having the same cuticle orientation was immersed in a 0.5 wt% sodium lauryl sulfate solution at 50 ° C. for 10 minutes. The hair sample was then prepared by washing with running water and drying. The hair bundled on one side with a wave efficiency measuring instrument was fixed with a rubber band, and the other end was alternately passed through the shaft without being loosened and pulled strongly, and fixed with the rubber band to the instrument. Next, in the pretreatment agent (Example 2) and the pretreatment agent containing only alkaline ionized water (Comparative Example 4) in which the egg white hydrolyzate was blended so that the concentration of the device fixing the hair was as shown in Table 2, respectively. It was immersed at 25 ° C. for 15 minutes (bath ratio 250 times). Then, it was immersed in a permanent wave first agent (release source: Sunny Place, Inc., trade name: Ion cis (super hard type)) at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Subsequently, it was immersed in a permanent wave second agent [Sunny Place Co., Ltd., trade name: Ion cis (super hard type)] at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Remove the sample from the instrument, place it gently on the glass plate, measure the length (b) of the first to fifth curl vertices, and calculate the wave efficiency using equation (1) .

  In Example 3, after immersing in a pretreatment agent containing egg white hydrolyzate so as to have the concentration shown in Table 2 at 25 ° C. for 15 minutes (bath ratio 250 times), towel drying, Dry at room temperature. The hair bundle that has been pre-treated in this way is attached to the wave efficiency measuring instrument on one side with a rubber band, and the other end is passed through the shaft alternately without loosening and pulling strongly. Fixed to the instrument. Then, it was immersed in a permanent wave first agent (release source: Sunny Place, Inc., trade name: Ion cis (super hard type)) at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Subsequently, it was immersed in a permanent wave second agent [Sunny Place Co., Ltd., trade name: Ion cis (super hard type)] at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Remove the sample from the instrument, place it gently on the glass plate, measure the length (b) of the first to fifth curl vertices, and calculate the wave efficiency using equation (1) .

  Furthermore, in Example 4, the device on which the hair was fixed was subjected to pretreatment in platinum amino ion water (pH 11.5) at 25 ° C. for 15 minutes (bath ratio 250 times). Then, permanent wave first agent (sales source: Sunny Place, Inc., trade name: AEON CIS (superhard type)) containing egg white hydrolyzate so as to have the concentrations shown in Table 2 at 25 ° C., 15 It was immersed for a minute (bath ratio 250 times) and washed with water. Subsequently, it was immersed in a permanent wave second agent [Sunny Place Co., Ltd., trade name: Ion cis (super hard type)] at 25 ° C. for 15 minutes (bath ratio 250 times) and washed with water. Remove the sample from the instrument, place it gently on the glass plate, measure the length (b) of the first to fifth curl vertices, and calculate the wave efficiency using equation (1) .

  Also, from Table 2, the wave efficiency is remarkably higher when the pretreatment is performed using the egg white hydrolyzate-containing composition (Examples 2 and 3) and when it is not performed (Comparative Example 4). It can be seen that not only the improvement but also the tensile cutting strength is improved. In addition, when the egg white hydrolyzate is added to the permanent wave first agent (Example 4), not only the wave efficiency is significantly improved, but also the tensile cutting strength is improved as compared with the case where it is not added. You can see that

Example 5 and Comparative Examples 5 and 6
By applying a bleaching agent [mandom Co., Ltd., trade name: Gatsby EX Hybrid] twice the weight to a commercially available black hair bundle of human hair (17.5 cm), leaving it at room temperature for 30 minutes, Damage treatment (high damage hair) was made by performing bleaching treatment and then performing 5 cycles, with the operation of drying the hair bundle with a hair dryer as one cycle. One hair is arbitrarily selected from the damaged hair produced as described above, and one third of the hair is selected as an untreated sample (Comparative Example 5), and the remaining two-thirds of the sample is adjusted to pH 9.0 with aqueous ammonia. For 10 minutes in a 4.0 wt% L-cysteine aqueous solution (bath ratio 1: 250) and washed with water for 1 minute (permanent wave first agent treatment). And half of this sample was immersed in a pretreatment agent containing 5.0 wt% egg white hydrolyzate at 25 ° C. for 15 minutes (bath ratio 250 times) (intermediate treatment). Next, the sample was immersed in a 6.0 wt% sodium bromate aqueous solution at 25 ° C. for 15 minutes (bath ratio 250 times), washed with water, and then air-dried at room temperature (permanent wave second agent treatment). A hair sample was prepared. Furthermore, the other half (permanent wave first agent-treated sample) was immersed in a 6.0 wt% sodium bromate aqueous solution at 25 ° C. for 15 minutes (bath ratio 250 times), washed with water, and then at room temperature. The hair sample of Comparative Example 6 was prepared by air drying.

Evaluation test D [analysis of amount of disulfide (-SS-) bond in hair by Raman spectroscopy]
The amount of disulfide (-SS-) bonds present inside damaged hair (high damage hair) was evaluated by the following method. Next, the hair sample obtained above or untreated damaged hair is frozen, a hair cross-section sample is prepared using a microtome (manufactured by Leica, product number: CM1800 type), and a micro Raman device (manufactured by Jobin Yvon, Using a product name: Ramanor T-6400, a Raman spectrum was measured in the direction of the inside of the hair (depth from the hair surface: 3 to 30 μm).

  For each hair sample, the area intensity of the SS band (SS) observed at 510 cm-1 is divided by the area intensity of the CH band (CH) observed at 1450 cm-1. The amount of disulfide (-SS-) bond inside the hair was calculated. And the average value and standard deviation of 7 points | pieces (distance of 3, 5, 7, 10, 15, 20, or 30 micrometers from the hair surface) cortex area | regions were calculated, and the significant difference test was performed. The results are shown in Table 3.

Evaluation test E [Evaluation of damage by observing hair cross section]
The hair cross-sectional sample obtained above was observed with an optical microscope (deformation of hair cross-sectional shape, peeling / cracking of cuticle region, cracking of cortex region).

  From the results shown in Table 3, when the risk wave is 5% or less and the permanent wave treatment is performed using L-cysteine (Comparative Example 6), the amount of disulfide bonds also decreases in the hair (cortex region). I understand that On the other hand, when the intermediate treatment is performed using the egg white hydrolyzate during the permanent wave treatment (Example 5), it can be seen that the amount of —SS— bonds in the hair is not decreased. This is presumably because the egg white hydrolyzate penetrates into the hair, and the -SS- bond is newly introduced into the hair, so that the wave efficiency and the tensile cutting strength are improved. In the case of the hair sample of Comparative Example 6, damage to the hair cross section (deformation of the hair shape, cracking of the cortex area, peeling of the cuticle and cracking) was confirmed, whereas in the case of the hair sample of Example 5 Hair damage was not confirmed. This suggests that the damage during permanent wave can be prevented when intermediate treatment is performed using egg white hydrolyzate.

  According to the present invention, it is possible to expect the effect of obtaining desired wave formation and straight formation without causing damage even with damaged hair (high damage hair) having a low -SS- content, and the use is wide and practical. There is a high utility value in a wide range of beauty industry fields.
