Description

  The present invention relates to a hair treatment agent comprising a permanent wave first agent containing an alkaline agent and a permanent wave second agent containing an oxidizing agent.

  Permanent wave treatment of hair skillfully utilizes disulfide bond (-SS-bond) cleavage (reduction step; first agent) and recombination (oxidation step; second agent) present in hair, 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. These reducing agents penetrate and diffuse into the hair, and function (curling performance, set Performance) (Non-Patent Document 1). For example, as a treatment agent, the first hair shape control agent having a high curl shape imparting effect and a high curly hair suppressing effect is known without causing excessive shrinkage even when hair damaged by chemical treatment is treated. (Patent Document 1). Further, it contains an alkali agent and a reducing agent, and the alkalinity defined by the consumption amount of 0.1N acid standard solution is 0.5 to 2.0 mL / pH within the range of pH 7.5 to 8.5. The 1st agent composition which exists in the range of g. A hair dyeing method for a two-bath type permanent wave agent containing the first agent composition is known (Patent Document 2).

  In recent years, along with the deregulation of the permanent wave standard, cosmetic curling materials containing reducing agents such as cysteamine hydrochloride, butyrolactone thiol, thiolactic acid, and sodium sulfite are commercially available.

  As an alkaline agent in such a permanent wave, amino alcohols such as monoethanolamine and triethanolamine are used. Among them, monoethanolamine is non-volatile and has a low odor, and therefore mainly has little odor. It is widely used as an alkaline agent in the type of permanent wave agent.

Kuzuhara, A .; Hori, T. Sen-i Gakkaishi 2003, 59 (4), 128-132.

  However, in the treatment agent having monoethanolamine as a main component, the monoethanolamine has an amino group in the molecule, and therefore has a strong affinity for hair, high hair persistence, and causes hair damage. In addition, it was also a cause of rough hands for the practitioner. For this reason, a method of applying one agent after water rod rolling has been proposed, but this method also has a problem that the reducing agent concentration decreases and the wave forming power decreases. Further, since hair damage occurs as the treatment time for the first agent is increased, a treatment agent having a short treatment time has been desired. Further, under high alkali, there is a problem in that the permanent wave and hair color cannot be simultaneously applied because the color of the dye dyed in advance with an oxidative hair dye or the like is lost.

  Then, this invention aims at providing the hair treatment agent which suppresses hair damage and rough hand of a practitioner, is excellent in wave formation power, glossiness, and touch, and can perform simultaneous treatment with a hair color. .

  In order to achieve the above object, the present inventors have intensively studied processing agents comprising various combinations, and as a result, have found the present invention.

That is, the hair treatment agent of the present invention is a hair treatment agent comprising a permanent wave first agent containing at least a reducing agent and a permanent wave second agent containing at least an oxidizing agent, wherein the permanent wave first agent is and a 0.01 to 10 wt% of thioglycerol, and ammonia, and N- acetylcysteine, and thioglycolic acid and its salts, cysteine and salts thereof, characterized by containing arginine.

  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.

In a preferred embodiment of the hair treatment agent of the present invention, the hair treatment agent further contains one or more selected from the group consisting of cysteamine and salts thereof, thiolactic acid and salts thereof, butyrolactone thiol, and sodium sulfite. It is characterized by that.

Moreover, in a preferred embodiment of the hair treatment agent of the present invention, the hair treatment agent further contains one or more selected from the group consisting of hydrolyzed keratin, hydroxypropyl chitosan, dilauroylglutamate sodium lysine. And

  Moreover, in a preferred embodiment of the hair treatment agent of the present invention, the pH of the hair treatment agent is in the range of 9.2 to 7.5.

  The hair treatment method of the present invention is characterized by using the hair treatment agent of the present invention.

  In a preferred embodiment of the hair treatment method of the present invention, the hair treatment is a permanent wave treatment or a hair straightening treatment.

  According to the present invention, it is possible to provide a permanent wave treatment agent that is capable of simultaneous treatment with a hair color and is excellent in curling performance (wave forming ability), and that hair damage and rough treatment of a practitioner can be prevented. There is an advantageous effect. Further, according to the hair treatment method of the present invention, the pretreatment agent containing alkaline reduced water is used to wind the rod without damaging the curling performance and without causing the operator to be rough by winding the rod. There is an advantageous effect that it can be formed.

First, the hair treatment agent of the present invention will be described. The hair treatment agent of the present invention is a hair treatment agent comprising a permanent wave first agent containing at least an alkaline agent and a permanent wave second agent containing at least an oxidizing agent, wherein the permanent wave first agent is 0. .1～10% by weight of thioglycerol, characterized by containing the ammonia. 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. First, the treatment agent will be described. Thioglycerin is a reducing agent with high moisturizing power, and can also be used as a reducing agent for coloring materials. The content of thioglycerin is from 0.01 to 10% by weight, preferably from 0.05 to 7% by weight, more preferably from the viewpoint of improving the safety to the scalp and hair and the wave forming ability. It can be made into 4 weight%.

While in the present invention contains ammonia, ammonia acts salt bond order to the hair swelling as an alkaline agent can assist the work of the active ingredient. In addition, since ammonia has high volatility, it has the advantage that hair persistence is extremely low, volatilizes during the standing time, and the pH of the drug is lowered, so that overtime hardly occurs. Therefore, it can be formulated as a treatment for soft hair and damaged hair, which are relatively susceptible to permanent waves. Furthermore, since the residual property to skin is low, it has the characteristic that there is little worry of a practitioner's rough hand. In the present invention, the ammonia content is not particularly limited as long as it contains ammonia, but from the viewpoint of improving safety to the skin and hair, and the ability to form waves, the ammonia content is 0.01-4. % By weight, more preferably 0.05 to 1% by weight.

  In the present invention, an unprecedented combination of thioglycerin and ammonia has an advantageous effect that the wave forming power (one of curling performance) is remarkably improved. This is apparent in the examples described later, and an effect exceeding the expectation that the treatment time is 5 minutes can be improved by 2.9 times compared with the wave force of thioglycolic acid.

  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 contained 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 wave bath type permanent wave agent containing thioglycolic acid or its salt as an active ingredient is the permanent wave second by cleaving the -SS- bond of hair with thioglycolic acid and alkali blended 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% of 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? 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 a thio-type permanent wave first agent, and a 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 to generate heat and the liquid temperature rises 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 straightener containing thioglycolic acid or its salts as the active ingredient is the same as the standard value of Permanent Wave 1st Agent and Permanent Wave 2nd Agent, and the reaction mechanism is the same as 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 1st agent or permanent wave 2nd agent, and the reaction mechanism is the above-mentioned thioglycolic acid or its salt. 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 for permanent wave 1st agent and permanent wave 2nd agent. 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 a preferred embodiment, the hair treatment agent further comprises at least one selected from the group consisting of thioglycolic acid and salts thereof, cysteine and salts thereof, cysteamine and salts thereof, thiolactic acid and salts thereof, and lactone thiols. Can be contained.

  Thioglycolic acid alone has an acidic pH, becomes a neutralized salt when combined with an alkali agent, has an effect as a strong reducing agent, and can also increase the swelling power. Thioglycolic acid quickly penetrates into the hair (cortex) while breaking the -SS- bond present in the hair. A permanent wave agent containing cysteine as an active ingredient can also be added as a cysteine stabilizer. The content of thioglycolic acid and its salts is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and wave forming ability. is there.

  Cysteine is moisturizing and can be formulated as a moisturizing agent in a permanent wave agent containing thioglycolic acid or a salt thereof that cleaves -SS- bonds in hair as an active ingredient. Since free amino groups in the molecule interact with negative ions on the hair surface, cysteine hardly penetrates into hair in healthy hair. Furthermore, since the -SS- bond in cortex is hardly cleaved, cysteine-treated hair has less hair damage than thioglycolic acid-treated hair. The content of cysteine and its salts is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and improving the wave forming ability. As cysteine salts, L-cysteine, L-cysteine hydrochloride, DL-cysteine, DL-cysteine hydrochloride and the like can be added.

  Cysteamine was originally used as a professional product in the overseas market under low pH (pH 8.3) conditions, but sensitization became a problem, and it has not been used in the United States since around 2001. Since cysteamine has a low molecular weight, it has high penetration into hair, and a strong wave effect equivalent to a permanent wave agent containing thioglycolic acid or a salt thereof as an active ingredient can be obtained at pH 8 and an equimolar concentration. However, due to the presence of amino groups in the molecule, it has been pointed out that it has a high persistence on hair and skin, and has a negative effect on sensitization, reaction odor, residual odor, and subsequent permanent treatment. . The content of cysteamine and its salts is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and improving the wave forming ability.

  Thiolactic acid has an intermediate reducing ability between thioglycolic acid and cysteine, and can be blended as an active ingredient of a permanent wave agent that cleaves -SS- bonds in hair. The content of thiolactic acid is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and improving the wave forming ability.

  Butyrolactone thiol (Brand name; Spira, raw material name: 2-mercapto-4-butanolide) is capable of waving even in the acidic region (pH = 7 or less) and has excellent characteristics such as very little hair damage. . On the other hand, it has a drawback that the raw material odor, reaction odor and residual odor are strong, and a masking method using a fragrance has been proposed. The content of butyrolactone thiol can be 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair, and wave forming ability. . As a commercially available product of butyrolactone thiol, for example, Spiera [Showa Denko Co., Ltd.] can be mentioned.

  Sodium sulfite (sulfite) has a characteristic that the reducing action is mild, but as a reaction product for hair, Bunte salt is formed, and there is a case where the hair is adversely affected. The content of sodium sulfite is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and improving the wave forming ability.

  In addition, the treating agent of the present invention can be exemplified by thiomalic acid, mercaptoethanol, dithiothreitol, sulfurous acid, hydrogen sulfite, thiosulfuric acid and salts thereof from the viewpoint of improving the wave forming ability. It can be used alone or in combination of two or more.

  Moreover, in a preferred embodiment of the hair treatment agent of the present invention, the hair treatment agent further contains N-acetylcysteine. N-acetylcysteine is also moisturizing and can be blended as a moisturizing agent in a waving agent containing thioglycolic acid or a salt thereof that cleaves -SS- bonds in hair as an active ingredient. In addition, when N-acetylcysteine is added to the combination of thioglycene, which is the main component of the present invention, and ammonia, it has not been clarified so far, but the gloss of hair after permanent wave treatment is remarkably improved. It was found. The content of N-acetylcysteine is 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, from the viewpoint of improving safety to the skin and hair and improving the wave forming ability.

  In a preferred embodiment, the hair treatment agent further contains one or more selected from the group consisting of arginine, hydrolyzed keratin, hydroxypropyl chitosan, dilauroyl glutamic acid sodium lysine.

  Arginine, as an alkaline agent, swells the hair and thus acts on the salt bond to help the active ingredient. Arginine is one of basic amino acids such as lysine. Compared with ammonia and aminoalcohols, arginine is weak in action as an alkaline agent, has a low odor, and hardly causes skin irritation. Arginine is one of the components contained in the cell membrane complex (CMC) of hair, and can be used not only as a CMC component but also as an alkaline agent. The content of arginine is 0.01 to 5% by weight, more preferably 0.05 to 2% by weight, not only as an alkaline agent but also from the viewpoint that a hair repair effect can be expected.

  The content of hydrolyzed keratin is from 0.01 to 5% by weight, more preferably from 0.05 to 2%, from the viewpoint of suppressing the drop in the tensile strength of hair after permanent wave treatment and improving the wave forming ability. % By weight. Examples of commercial products of hydrolyzed keratin include Promois WK, Promois WK-L, Promois WK-H, Promois WK-GB [above, Seiwa Kasei Co., Ltd.], and these may be used alone or in two types. It can be used in combination of the above.

  The content of hydroxypropyl chitosan is 0.005 to 4% by weight, more preferably 0.01 to 1% by weight, from the viewpoint of improving the firmness of the hair and the tensile cutting strength. Examples of commercially available products of hydroxypropyl chitosan include chitofilmer, chitofilmer HV, chitofilmer 10 [or more, Ichimaru Falcos Co., Ltd.], and these may be used alone or in combination of two or more. it can.

  The content of dilauroyl glutamate ricin sodium is 0.01 to 5% by weight, more preferably 0.05 to 2% by weight from the viewpoint that dilauroyl glutamate lysine sodium easily penetrates into the hair and can be expected to have a hair repair effect. It is. As a commercial item of sodium dilauroyl glutamate, Perisea L-30 [Asahi Kasei Chemicals Corporation] is mentioned, for example.

  From the viewpoint that alkaline agents such as monoethanolamine and triethanolamine are non-volatile, have high persistence, do not change PH even when oxidized, and are said to be suitable for healthy hair, which is relatively hard to get permanent. It is preferable to use an alkaline agent other than the above.

  The permanent wave first agent has a pH range of 6 to 10 in general, and is not particularly limited, but is preferably from the viewpoint of suppressing hair damage and improving wave forming ability. Is 7.0 to 9.5, more preferably, the pH of the hair treatment agent is in the range of 7.5 to 9.2.

  The main components of the permanent wave agent according to the present invention are as described above, but the following additives may be added as necessary.

  In addition, as an alkaline agent, aminoethanols such as triethanolamine, isopropanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, L-arginine, etc. These basic amino acids, carbonates such as ammonium carbonate, ammonium hydrogen carbonate, sodium carbonate and sodium hydrogen carbonate, caustic alkalis such as potassium hydroxide and sodium hydroxide, morpholine and the like can be added.

About the addition method, it is a conventional method.

  The permanent wave agent according to the present invention can be provided in a liquid form, a milk form, a cream form, a mousse form, an aerosol form or the like according to a normal method for both the first and second agents.

  The hair treatment method of the present invention is characterized by using the hair treatment agent of the present invention. In a preferred embodiment of the hair treatment method of the present invention, the hair treatment is a permanent wave treatment or a hair straightening treatment.

  In a preferred embodiment of the hair treatment method of the present invention, the pretreatment is performed by applying the pretreatment agent containing alkali-reduced water and then applying the above-described hair treatment agent of the present invention.

  The hair treatment method of the present invention will be described as follows. That is, the permanent wave (hair treatment agent) first agent containing the above components is applied to the hair in the same manner as the normal permanent wave first agent, and left for about 5 to 30 minutes to soften the hair. The permanent wave first agent can be applied before the hair is wound around the rod or after the hair is wound around the rod, or may be applied twice before and after the hair is wound around the rod. The standing time after the application of the permanent wave first agent is appropriately adjusted in the same manner as the standing time of the conventional permanent wave first agent treatment depending on the degree of damage to the hair, the hair quality, the strength of the action of the agent used, and the like. At this time, in a preferred embodiment, as a pretreatment, after applying a pretreatment agent containing alkali-reduced water, the above-described hair treatment agent of the present invention may be applied.

  Next, the hair after the first treatment is washed with water, and the hair is dried by air drying. Washing with water can be performed by general washing with water as before. For air drying, air is sucked from the inside of the rod around which the hair is wound, and air is passed through the rod and the hair wound around it to dry it, or air is supplied from the outer periphery of the rod around which the hair is wound. Conventionally known methods such as a method of drying and a method of drying by diffusing wind from the inside of a rod around which hair is wound to the outside can be used. The temperature of the wind supplied to the hair in air drying is 60 ° C. or less, more preferably around 45 ° C.

  By washing with water and air drying, the hydrogen bonds are opened in the hair. When the treatment is performed with the permanent wave second agent after this state is reached, the wave state wound around the rod when dried by air drying is stored in the hair. A permanent wave second agent containing an oxidizing agent is applied to the hair after washing and drying, and after leaving it to stand out, it is rodd out and then washed with water. Examples of the oxidizing agent used in such a permanent wave second agent include hydrogen peroxide, sodium bromate, and potassium bromate. The blending amount of the oxidizing agent is 0.5 to 3.0% by weight for hydrogen peroxide and 2 to 10% by weight for sodium bromate. The standing time is 3 to 8 minutes when hydrogen peroxide is added, and 8 to 15 minutes with sodium bromate. If the standing time is short, the oxidation treatment is insufficient and wave formation tends to be insufficient, and if the standing time is too long, the hair may be damaged. After finishing the permanent wave second agent treatment, rod out and wash with water to sufficiently remove the remaining permanent wave second agent treatment. At this time, a treatment agent may be used in combination. In addition, after washing with water, general treatments associated with permanent wave treatment such as drying and setting of hair with a hair styling agent are performed.

  As mentioned above, although the hair processing method using the hair processing agent of this invention was mainly demonstrated to the case of the case of the permanent wave processing agent, you may use a hair processing agent as a curly hair correction processing agent. The hair treatment method in the case of using as a hair straightening treatment agent can perform a hair treatment according to a conventional method except using the hair treatment agent of this invention.

  Examples of the present invention will now be described, but the present invention is not construed as being limited to the following examples. Moreover, it cannot be overemphasized that it can change suitably, without deviating from the summary of this invention.

(Preparation of hair sample)
According to the composition described in Table 1 below, the first permanent wave agent of Examples 1 to 5 and Comparative Examples 1 to 2 was prepared. As the second agent, 8 wt% sodium bromate aqueous solution was used. While applying 1 g of the first agent to 1 g of flat hair bundle (20 cm), it was wound around a rod, left at room temperature for 15 minutes, washed with water, and towel-dried. Next, 1 g of the second agent was applied and allowed to stand at room temperature for 15 minutes, and then the rod was removed and washed with water. Towel was dried and dried at room temperature. The following sensory evaluation was carried out using these hair samples.

  First, the effect by this invention was evaluated by the sensory test. Specifically, various samples were prepared, an ingredient table was prepared, and sensory evaluation on the gloss, softness, moisture retention, and hair damage suppression after permanent wave treatment was examined. The sensory test was conducted by 10 people. Table 1 shows the component composition of the permanent wave first agent.

  Table 2 shows the sensory evaluation results for glossiness (sensory evaluation with 10 people).

  Table 3 shows the sensory evaluation results for softness and moisture retention (sensory evaluation with 10 people).

  Table 4 shows the sensory test results for the suppression of damage (sensory evaluation with 10 people).

Permanent wave (hair treatment agent) 1st agent uses the ingredients of Samples 1-5 and Comparative products 1 and 2 respectively, and Permanent Wave 2nd agent uses the same ones, wave feel and moisture retention Comparison of damage suppression.
As a result, the sample 3 according to the present invention may be any of glossiness, softness, moisture retention, and suppression of damage, and then samples 1, 2, 4, and 5 according to the present invention are good. The comparative products 1 and 2 containing ethanolamine have difficulty in any respect.

Table 5 shows the wave efficiencies (25 ° C., 5 to 15 minutes, bath ratio 250 times) of various reducing agents depending on the difference in alkaline agent. Here, as the first agent, an equimolar concentration (65 mM) of a reducing agent (thioglycolic acid, thioglycerin) was blended, and the pH was adjusted to 9.0 beforehand with an alkaline agent (ammonia, monoethanolamine). I used something.

The wave efficiency was measured according to the Kirby method (Kirby, DH Drug & Cosmetic Industry, 1957, 80 (3), 314.). A bundle of 20 human healthy hairs with a cuticle orientation (length 20 cm) 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, the device on which the hair was fixed was immersed in the first agent at 25 ° C. for 5 to 15 minutes (bath ratio 250 times) and washed with water. Finally, it was immersed in a 6% aqueous solution of sodium bromate 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) . 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)

  For thioglycolic acid, there was no difference in wave efficiency due to the difference between ammonia and monoethanolamine, but for thioglycerin, the addition of ammonia significantly improved the wave efficiency. I found it. Therefore, it has been found that when a permanent wave agent in which ammonia is mixed with thioglycerin is used, it can be waved in a short time, so that an extremely excellent effect of suppressing hair damage can be achieved.
