Description

  The present invention relates to a wave forming agent for human damaged hair or synthetic protein fiber, and a wave forming method for applying a permanent wave to damaged hair or synthetic protein fiber of human hair.

  In detail, the present invention is related to the conventional chemical reaction of reduction / oxidation, and damage to the hair becomes serious. The present invention relates to a wave agent and a wave forming method for applying a permanent wave to hair and a synthetic protein fiber which is not easily affected by a chemical reaction of reduction and oxidation.

Permanent wave is a treatment that gives a permanent wave or curl of a desired shape to human hair or wool. Human hair and wool are composed of a special fiber called keratin protein containing about 15% cystine, so there are side chain bonds such as disulfide bonds, salt bonds, and hydrogen bonds. It has a special α-helix structure.

  In the conventional permanent method using the reduction / oxidation reaction, the reducing agent in the component of the wave agent of the reduction / oxidation reaction acts on the disulfide bond of the side chain bond to break the disulfide bond, and the component of the wave agent The alkaline agent in the side agent acts on the salt bond of the side chain bond to break the salt bond, and the water in the component of the wave agent acts on the hydrogen bond of the side chain bond to break the hydrogen bond, Swell and soften hair and wool. However, in reality, even though the disulfide bond, salt bond, and hydrogen bond are cut, only a part of each bond is cut, but depending on the degree of damage to the hair, all side chain bonds are broken. In some cases, the hair is cut (the hair melts).

  Specifically, wave formation that applies a permanent wave to human hair and wool is a combination of disulfide bonds (RS-SR) in the side chains of keratin protein fibers of hair and wool, thioglycolate, cysteine, sulfite, cysteamine hydrochloride Cut with a reducing agent such as salt, 2-mercapto-4-butanolide (RSH HSR), wrap around the hair and wool with an instrument (rod), and give the hair and wool a rod shape By using an oxidizing agent such as bromate or hydrogen peroxide, the wave shape is fixed by recombining disulfide bonds (RS-SR), and a permanent wave is applied.

However, this conventional technique has a problem of softening the hair protein and damaging the hair because it uses a reducing agent and an alkaline agent for cleaving the side chain cystine bond. In addition, with the recent hair dyeing / bleaching treatment and hair straightening treatment due to the trend of white hair dyeing and fashion dyeing, human hair becomes extremely damaged and the hair cuticle covering the surface of the hair (Cuticle) is extremely deficient, and the side chain bonds of the keratin protein fibers forming the hair are severely cleaved and lost, especially the disulfide bond cleaved and lost, and the hair that does not have a permanent wave in the reduction / oxidation chemical reaction Or, the hair that is difficult to wear is increasing, and the hair that is extremely damaged by the conventional permanent agent is increasing.

  Further, the conventional permanent wave treatment method has a drawback that it takes time to perform the treatment, and the physical and mental burden of the person to be treated is large.

  Therefore, a two-bath shape memory wave forming agent containing silicon, a nonionic surfactant, and keratin having an average molecular weight of 20,000 or less has been proposed (see Patent Document 1).

  In recent years, synthetic protein fibers have been used as substitutes for human hair in wigs, hair pieces, doll hairs, and the like. And it is required to apply a permanent wave to a wig, a hair piece, a doll hair or the like using these synthetic protein fibers.

  However, the synthetic protein fiber has a structure that is different from the fiber structure of human hair and wool, regardless of whether the protein constituting the fiber is keratin, collagen, silk, etc. or with or without cystine. In the same chemical reaction of reduction and oxidation as that of human hair and wool, it was difficult to apply a permanent wave with sufficient curl formation and retention.

  Therefore, as a method for setting such a synthetic protein fiber (permanent wave is applied), a setting method is proposed in which the regenerated collagen fiber is heat-set by wet heat treatment at 50 ° C. to 160 ° C. and drying treatment at 20 ° C. to 220 ° C. (See Patent Document 2).

JP 2005-179271 A International Publication No. 2002/052099 Pamphlet

  However, the prior art described in Patent Document 1 is a two-bath type wave forming agent and a wave forming method. This method takes time to perform the treatment, and the physical and mental burden of the patient is reduced. The disadvantage of being large was not solved sufficiently. In addition to keratin, it is essential to contain a plurality of compounds such as silicon, and the composition and preparation thereof are complicated.

  In the prior art described in Patent Document 2, a desired wave can be formed once, but the formed wave can be easily removed by shampoo or the like, and the wave can be fixed over a long period of time. There wasn't. That is, I couldn't apply a permanent wave.

  According to the present invention as described above, without breaking the disulfide bond, without damaging the hair, a wave is formed on the damaged hair, or a wave is formed on the synthetic protein fiber. It became possible to fix over. In addition, the agent used to form such a wave can be easily prepared with a simple composition. Furthermore, it has become possible to perform a wave forming treatment on hair in a short time.

  Hereinafter, embodiments of the present invention will be described in detail. The wave forming agent for human damaged hair and the wave forming agent for synthetic protein fiber of the present invention contain a compound having an α-amino acid in the molecule, and as one embodiment thereof, a compound having an α-amino acid in the molecule and It consists of water and is composed of an aqueous solution of a compound having an α-amino acid in the molecule. In addition, the wave forming agent for human damaged hair and the wave forming agent for synthetic protein fiber of the present invention are not intended for healthy hair of human hair. This is because the effect is not recognized on healthy hair as described later.

  The damaged hair includes normal damaged hair and super-damaged hair. The strength of keratin protein fibers (furous fibers) in human hair and hair is maintained by a matrix that is filled with paracortex and orthocortex. This matrix is easily eluted from between paracortex and orthocortex by bleaching, hair dye, and strong shampooing agent to reduce the cell membrane complex between the hair and skin. Become thin.

  The healthy hair of human hair means hair having a close contact with the cuticle, a cell membrane complex between the cuticles, and normal fur fibers. Since such healthy hair has normal disulfide bonds, permanent waves can be applied by a conventional method using a reducing agent and an oxidizing agent. When about 10 healthy hairs of straight hair are bundled and folded strongly in half by human power, the hand returns to the original straight hair.

  On the other hand, normal damaged hair refers to hair with a part of the hair skin peeled off, the cell membrane complex that adheres to the hair skin is lost, and the fur fibers are also in a thin state. To do. Since such normal damaged hair has a reduced matrix and disulfide bonds, the hair tends to swell due to the reducing agent and alkali, and the permeation of the reducing agent is fast, so the perm reaction is fast and strong. It tends to be too much. When this damaged hair is permed with a conventional permanent agent using a reducing agent and an oxidizing agent, damage to the hair becomes more serious than before the perm is applied. And if you take a hand after bundling about 10 normal damaged hairs in a bunch and fold it in half by hand, the cuticle is lost and the fur is slightly rough. It does not return to straight hair and remains slightly broken.

  The super-damaged hair means hair that has almost all of the cuticle peeled off, the fur is exposed, and the fur fibers are very thin. Such super-damaged hair will not be cut if it has a pulling force of about 20 g when it is dry, but will be cut with a very slight force when it contains moisture. When permanent wave is applied using a chemical reaction of reduction / oxidation, cystine is almost lost, so there is no permanent on the hair, or hair is easily cut by applying shampoo. Or melt. When about 10 super-damaged hairs of straight hair are bundled and folded strongly by human power and then released, they are hardly returned and remain broken.

  From the above, the perm of healthy hair is weak, and the extent of perm gradually increases from mildly damaged hair to some degree of damaged hair. Perm is strongly applied depending on the degree of damage, such as about 20 mm for damaged hair and about 15 mm for normal damaged hair. However, when disulfide bonds in keratin protein decrease, it becomes difficult to apply perm and most cystine. When lost, that is, in the case of super-damaged hair, the hair dissolves.

  The compound having an α-amino acid in the molecule used in the present invention is not particularly limited. For example, a protein comprising an α-amino acid, a compound in which an α-amino acid and a hydrocarbon are bonded, and an α-amino acid in the molecule And semi-synthetic polymer compounds having a peptide bond and a silicon atom.

  And one embodiment of the wave forming agent for damaged hair and the wave forming agent for synthetic protein fiber of the present invention contains a protein comprising an α-amino acid, for example, comprising a protein comprising an α-amino acid and water, It consists of an aqueous solution of protein consisting of α-amino acids.

  The α-amino acid protein used in the present invention is not particularly limited as long as it has a number average molecular weight in the range of 400 to 40,000, but in the case of a wave forming agent for damaged hair of human hair, the number average molecular weight is 400 to 1, 000 is desirable. This is because although a permanent wave is applied at a molecular weight of 1,000 or more, it is inferior to a wave forming force and a holding force which are desirable from a subject who desires a permanent wave. In the case of a wave forming agent for synthetic protein fibers, a number average molecular weight of 400 to 30,000 is preferred. Within this range, the desired permanent wave is applied and the difference in wave holding power is very small.

  In addition, it is preferable that the protein consisting of α-amino acid is completely dissolved in water. If the amount of protein consisting of α-amino acid is more than 20% by weight, it is not completely dissolved. Since no effect is observed, the amount of α-amino acid protein is preferably in the range of 1 to 20% by weight. More preferably, it is in the range of 6 to 20% by weight.

  In addition, it is preferable that the compound in which α-amino acid and hydrocarbon are bonded is completely dissolved in water. If the compound in which α-amino acid and hydrocarbon are bonded is more than 20% by weight, the compound is not completely dissolved. When the amount is less than% by weight, almost no effect is observed, so the compound in which the α-amino acid and the hydrocarbon are bonded is preferably in the range of 1 to 20% by weight. More preferably, it is the range of 7-20 weight%.

  In addition, the wave forming agent for damaged human hair and the wave forming agent for synthetic protein fiber of the present invention contain a semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom in the molecule. For example, a semi-synthetic polymer having a peptide bond between α-amino acids in the molecule and a silicon atom and water, and a semi-synthetic polymer having a peptide bond between α-amino acids and a silicon atom in the molecule It consists of an aqueous solution of the compound.

  Examples of the semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom in the molecule include hydrolyzed sesame protein PGpropylmethylsilanediol, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed keratin , (Dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed silk, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed wheat protein, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed collagen, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed soybean protein , Silanetriol arginine, (hydrolyzed silk / PG-propylmethylsilanediol) crosspolymer, hydrolyzed vegetable protein PGpro Rumethylsilane diol, glutamic acid silane triol, PCA-Na methyl silanol, aspartic acid methyl silanol hydroxyproline, lysine silane triol, etc. may be included, or one or more kinds selected from these may be mixed and contained.

  Further, it is preferable that a semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom is completely dissolved in water, and a semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom is preferable. If it exceeds 20% by weight, it does not completely dissolve, and if it is less than 1% by weight, almost no effect is observed. Therefore, a semi-synthetic polymer having a peptide bond between α-amino acids and a silicon atom. The compound is preferably in the range of 1 to 20% by weight. More preferably, it is the range of 7-20 weight%.

  In the above-mentioned wave forming agent for damaged hair of humans and the wave forming agent for synthetic protein fibers of the present invention, components that are usually used as additives other than those described above are within a range that does not impair the purpose, action, and effect of the present invention. It can be appropriately selected and used. Examples of these additives include base materials, excipients, emulsifiers, dispersants, solubilizers, solvents, alkali agents, pH adjusters, viscosity adjusters, antifoaming agents, flavoring agents, bactericides, and colorants. Antioxidants, stabilizers, sequestering agents, preservatives, wetting agents, hair protecting agents, antistatic agents, perfumes, antifungal agents, suspending agents, thickeners can be used.

  Next, the wave forming method for human damaged hair or synthetic protein fiber of the present invention will be described. These wave forming methods include a wave forming agent for human damaged hair containing a compound having an α-amino acid in the molecule, and as one embodiment, a compound having an α-amino acid in the molecule and water. It is a method comprising a step of applying the prepared aqueous solution to human damaged hair or synthetic protein fiber. The term “coating” is not limited to the meaning of applying with a brush or the like, but includes the action of attaching the aqueous solution to human damaged hair or synthetic protein fiber widely, and the damaged hair or synthetic protein fiber in the aqueous solution of the present invention. It also includes the act of soaking the hair or applying it to damaged hair or synthetic protein fiber with a spray or the like.

  Specifically, as a one-bath type, a damaged hair or synthetic protein fiber is moistened with water, and any of the above wave forming agents is applied, preferably gently combed with a comb, and the wave forming agent of the present invention is applied. Infiltrate, wrap around a rod of desired diameter, let stand, and after 30 minutes, remove the rod and plain rinse. After plain rinse, dry with a dryer or the like.

  Alternatively, a two-bath type may be employed for the hair. In this case, the damaged hair is moistened with water, and any of the above-mentioned wave forming agents is applied, preferably gently combed with a comb to infiltrate the wave forming agent of the present invention, wound around a rod of a desired diameter, and 10 minutes. Leave it naturally, wash it with water as you like, apply an oxidizing agent such as hydrogen peroxide, sodium perborate, potassium bromate or sodium bromate to the damaged hair, let it stand for about 10 minutes, and remove the rod. Plain rinse. After plain rinse, dry with a dryer or the like.

  In the above-described method, the wave forming agent may be applied after the damaged hair or synthetic protein fiber is wound around the rod, instead of applying the wave forming agent before winding around the rod. The step of moistening the synthetic protein fiber with water may be omitted. Further, the time for winding around the rod can be appropriately set to an appropriate time depending on the degree of damage of damaged hair, the hair quality, the type of synthetic protein fiber, and the like.

  Wave forming agent consisting of α-amino acid protein and water, α-amino acid and hydrocarbon bonded compound, and water forming agent for normal hair of human hair, super-damaged hair and synthetic protein fiber, respectively Alternatively, a wave forming agent comprising a peptide bond between α-amino acids in the molecule and a semi-synthetic polymer compound having a silicon atom and water was used for the test. Each aqueous solution contains 20% by weight of a protein composed of α-amino acid, a compound in which α-amino acid and hydrocarbon are bonded, and a semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom in the molecule, An aqueous solution (purity 20% aqueous solution) prepared with purified water was used for the remainder.

  Further, as a comparative example, a wave forming agent composed of a protein consisting of α-amino acid and water, a wave forming agent composed of a compound of α-amino acid and hydrocarbon bonded to water, or a water forming agent composed of water, or α in the molecule. -A wave forming agent consisting of a semi-synthetic polymer compound having a peptide bond between amino acids and a silicon atom and water was used for the test.

  Furthermore, as a comparative example, a test was conducted using water instead of the above-mentioned wave forming agent, and for comparison with a general permanent wave agent, a thioglycolic acid-based permanent agent (Liveness DX Sowan Co., Ltd.), cysteine-based The perm preparation (Liveness SDX Sowan Co., Ltd.) was used for the test.

For human hair, an untreated hair bundle having a length of 20 cm was used as human hair, and the untreated hair bundle was subjected to a bleach treatment twice as normal damaged hair. A hair bundle that has been artificially damaged is used as normal damaged hair, and as undamaged hair, the untreated hair bundle is subjected to bleaching treatment six times to obtain a hair bundle that has artificially damaged healthy hair. Used as super-damaged hair. As the synthetic protein fiber, a regenerated collagen fiber (“ULTIMA” manufactured by Kaneka Corporation) was used to form a bundle having a length of 20 cm.

As a test method, moisturize normal damaged hair, super-damaged hair, synthetic protein fiber and human hair of human hair with water, apply each wave forming agent, carefully with a comb Then, the wave forming agent was infiltrated, wound around a rod having a diameter of 10 mm, and after 30 minutes, the rod was removed and plain rinse was performed. After plain rinsing for 24 hours, the curl diameter was measured. This diameter is referred to as the diameter after cold water treatment. Thereafter, the dried hair bundle was shampooed 10 times, naturally dried for 24 hours, and then the curl diameter was measured again. This diameter is referred to as the diameter after cleaning. The unit of the measurement result is cm. Then, the diameter of the curl after the cold water treatment and the diameter of the curl after the washing treatment were compared to determine whether the perm was applied or whether it was a temporary set. Even if the diameter after the cold water treatment is small, those having a large diameter after the washing treatment are judged to have a temporary set and wave forming power but no holding power. That is, it can be said that the smaller the curl diameter after the cleaning treatment, the more the set, wave forming force and holding force, that is, the permanent wave is applied.

  In the beauty world, there is no particular criterion for determining the degree of permanent wave. Therefore, it is judged that a strong perm is applied when the diameter of the rod becomes 1 to 2 times the diameter of the rod after the cleaning process, and it is normal when the diameter is 2.1 to 3 times the diameter of the rod. It is judged that a permanent is applied to the rod, and if it is 3.1 to 4 times the diameter of the rod, it is judged that a weak permanent is applied. It was judged that a weak perm was applied, and when it was more than 5 times the diameter of the rod, it was judged that it was hardly applied.

  In a comparative example using a thioglycolic acid-based permanent agent and a cysteine-based permanent agent, the hair bundle is moistened with water, wound around a rod having a diameter of 10 mm, applied with one permanent wave agent, and applied for 5 minutes. After heating at about 45 degrees with a warmer, it was left to stand at room temperature for 10 minutes. Thereafter, two permanent wave agents were applied and allowed to stand for 10 minutes, after which the rod was removed and plain rinsed. After leaving for 24 hours after plain rinse, the curl diameter was measured (diameter after cold water treatment). Thereafter, the dried hair bundle was shampooed 10 times, naturally dried for 24 hours, and then the diameter of the curl was measured again (diameter after washing treatment).

Although not clear from the above table or the results shown in the following table, among disulfide bonds, salt bonds, and hydrogen bonds, hydrogen bonds are cleaved by wetting with water (absorbing moisture) and dried. Are recombined. The reaction of applying a permanent wave to human hair and wool through a chemical reaction of reduction and oxidation acts on the disulfide bond of the side chain bond, does not act on the hydrogen bond, and does not act on the salt bond.

Therefore, there is a difference in the diameter of the wave when wet with the water of the hair of a person who has applied a permanent wave, the diameter of the wave after drying, and the extent to the healthy hair and damaged hair.

In other words, the hair of a person with a permanent wave appears to have a strong perm because the hydrogen bond is broken when wet. However, the curl gradually increases as it dries, and when it completely dries, it becomes a larger percentage. The reason for this is that when a permanent wave is applied, the hydrogen bond is broken by moisture in the permanent wave agent, but the hydrogen bond broken at that time is only a temporary break, and the subsequent drying causes the original bond to be restored. Because it returns to the hair.

Depending on the treatment conditions etc., for example, if it is about 25 mm for healthy hair when applied with a 10 mm diameter rod, about 20 mm for mildly damaged hair, about 15 mm for normal damaged hair, etc. Even if the same wave agent and the same rod are used, the degree of application varies. Also, compared to the diameter when wet, generally any hair has a curl of about 30% when dry.

  However, since the synthetic protein fiber is a polymer of amino acids and has no side chain bond, there is no difference in the diameter of the curl when it is wet or dry.

Table 1 shows test results for normal damaged hair, Table 2 shows test results for super damaged hair, Table 3 shows test results for synthetic protein fibers, and Table 4 shows test results for healthy hair as a comparative example. Examples 1 to 14, 32 to 45 and 63 to 76 and Comparative Examples 10 to 23 shown in Tables 1 to 4 are wave forming agents consisting only of α-amino acid protein and water, Examples 15 to 28, 46. ~ 59, 77-90 and Comparative Examples 24-37 are wave forming agents consisting only of a compound in which an α-amino acid and a hydrocarbon are combined and water, Examples 29-31, 60-62, 91-93 and Comparative Examples 38- 40 is a wave forming agent composed of only a semi-synthetic polymer compound having a peptide bond between α-amino acids and a silicon atom in the molecule and water. In Tables 1 to 15 below, damaged hair means normal damaged hair.

From the above results, as is clear from Table 4, for the healthy hair of the comparative example, a protein comprising an α-amino acid having an amino group and a carboxyl group in the molecule, a compound in which an α-amino acid and a hydrocarbon are bonded. In a semi-synthetic polymer compound having a peptide bond between α-amino acids in the molecule and a silicon atom, both the diameter after cold water treatment and the diameter after washing treatment are all at least 5 times the diameter of the rod based on the above criteria. Therefore, it can be seen that the wave forming power and holding power are extremely weak. Moreover, in the water of Comparative Example 41, the hair returned to straight hair after the cleaning treatment, and no wave formation was seen, so measurement was impossible.

Since the permanent agent of thioglycolic acid and the cysteine-based permanent agent of Comparative Examples 42 and 43 are permanent agents applied by reduction / oxidation reaction, normal or weak perms were applied to healthy hair.

Further, as is apparent from Table 1, it can be seen that perm is applied to the normal damaged hair as a result of 2.32 times to 4.18 times the rod diameter. In the water of Comparative Example 1, it can be seen that the wave forming force is weak and the holding force is extremely weak. In the thioglycolic acid permanent agent and the cysteine-based permanent agent of Comparative Examples 2 and 3, as described above, the permanent hair is weak in healthy hair, and the degree of perm is gradually increased from mildly damaged hair to some damaged hair. Because it becomes stronger, it has a strong perm. However, the use of a reducing agent and an oxidizing agent damages the hair and makes the damage more severe.

Further, as is apparent from Table 2, it can be seen that the super-damaged hair is permed as a result of 2.02 to 2.96 times the rod diameter. In the water of Comparative Example 4, it can be seen that the wave forming force is weak and the holding force is extremely weak. As described above, the permanent agent of thioglycolic acid and the cysteine-based permanent agent of Comparative Examples 2 and 3 do not have perm at all in the case of super-damaged hair. Was damaged, and the hair melted, making it impossible to measure.

Further, as is clear from Table 3, it can be seen that the synthetic protein fiber is permed as a result of 2.3 to 3.56 times the rod diameter. In the water of Comparative Example 7, it can be seen that the wave forming force is weak and the holding force is extremely weak. In the thioglycolic acid permanent agent and the cysteine-based permanent agent of Comparative Examples 8 and 9, a loose permanent was applied as a result of 3.63 times and 3.69 times the rod diameter. It turns out that it is permanent and has high holding power.

  From the above results, the curl diameter in the hydrolyzed keratin aqueous solution is remarkably small for all normal damaged hair, super-damaged hair, and synthetic protein fiber, and the wave forming ability and holding power are more excellent. all right.

  In the tests in Tables 1 to 4, an aqueous solution of hydrolyzed keratin having a number average molecular weight of 400 was used, but hydrolyzed keratin commercially available as a cosmetic raw material has a number average molecular weight of 400, 1,000, 4,000, There are various molecular weights such as 10,000 and 30,000, and there are also powdered hydrolyzed keratin powders. Therefore, in order to investigate the number average molecular weight with excellent wave forming ability, the number average molecular weight of 400, 1,000, 4,000, 10,000, and 30,000 hydrolyzed keratin was tested by the difference in number average molecular weight. did. The results are shown in Tables 5 to 7.

  Based on the above results, it is considered that the normal damaged hair and super-damaged hair exist because the hair dermis is present even though it is peeled off, but it is extremely small in the hydrolyzed keratin aqueous solution having a number average molecular weight of 400. The curl diameter was obtained, and it was found that the lower the number average molecular weight, the better the wave forming ability and holding power. Further, unlike the damaged hair of human hair, synthetic protein fiber seems to be because the cuticles (cuticles) present in human hair and wool are not structurally present, but easily penetrates regardless of the molecular weight. It was found that all the number average molecular weights were excellent in forming power and holding power almost uniformly.

In the above examples, the test was carried out using an aqueous solution containing 20% by weight of a compound having an α-amino acid in the molecule and a 20% purity aqueous solution prepared with purified water as the balance. In order to confirm the preferred blending amount, the difference in wave forming power due to the difference in blending amount was examined. As a comparative example, a 0% pure aqueous solution containing only purified water containing no compound having an α-amino acid in the molecule was also tested.

  First, the blending amount of hydrolyzed keratin having a number average molecular weight of 400 is changed, and the remainder uses each wave forming agent prepared with purified water. Each of hair and synthetic protein fiber was tested. The results are shown in Table 8.

  The results of the same test conducted with hydrolyzed collagen having a number average molecular weight of 4,000 are shown in Table 9, the results conducted with hydrolyzed rice protein in Table 10, the results conducted with isostearoyl hydrolyzed silk in Table 11, The results obtained with cocoyl glutamic acid TEA are shown in Table 12, the results obtained with cationized hydrolyzed soy protein in Table 13, the results obtained with hydroxypropyltrimonium hydrolyzed keratin in Table 14, and (dihydroxymethylsilylpropoxy) Results obtained with hydroxypropyl hydrolyzed keratin are shown in Table 15.

  From the above results, compounds having an α-amino acid in the molecule, specifically, a protein comprising an α-amino acid, a compound in which an α-amino acid and a hydrocarbon are bonded, or a peptide bond between α-amino acids in the molecule It turns out that a permanent wave is applied by containing 1 weight% or more of the semisynthetic polymer compound which has a silicon atom, without being limited to content.
