Abstract
Description
Technical Field
[0001] The present invention relates to a permanent wave pretreatment agent, a permanent wave first agent, and a permanent wave method.
Background Art
[0002] In a perming process for changing the shape of hair, a perming agent containing a reducing agent is used to cut the disulfide bonds of the keratin protein in the hair, thereby changing the shape of the hair. Thereafter, disulfide groups are formed by air oxidation or a second perming agent containing an oxidizing agent.
[0003] As such a perming process, for example, as described in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2018-162226), by using a perming agent having a reducing agent content of 3% by mass or more and 10% by mass or less and a pH of 7.0 or more and 9.0 or less, it has been proposed to improve the balance between hair deformation and suppression of a fluffy feeling.

The blending amount of the cationic surfactant in the pretreatment agent of the first embodiment is, for example, 0.1% by mass or more and 4% by mass or less.
[0023] As the higher alcohol, a monohydric alcohol having 14 to 22 carbon atoms (for example, linear saturated alcohol, linear unsaturated alcohol, branched saturated alcohol) can be used. The blending amount of the higher alcohol in the treatment agent of the first embodiment is, for example, 1% by mass or more and 8% by mass or less.
[0024] Examples of polyhydric alcohols include ethylene glycol, propylene glycol (1,2-propanediol), 1,3-propanediol, glycerin, 1,3-butylene glycol, diethylene glycol, pentylene glycol, diglycerin, hexanediol, octanediol, tripropylene glycol, polyglycerin-3, polyethylene glycol 300, polyethylene glycol 400, and polyethylene glycol 600. The amount of polyhydric alcohol in the pretreatment agent of the first embodiment is, for example, 0.01% by mass or more and 10% by mass or less.
[0025] The acid may be either an organic acid or an inorganic acid. Examples of organic acids include malic acid, lactic acid, tartaric acid, citric acid, succinic acid, and glycolic acid.

[0027] The dosage form of the pretreatment agent in the first embodiment is not particularly limited and can be liquid, cream, gel, foam, mist, etc. From the viewpoint of easy uniform application to the hair, a liquid dosage form is preferred for the pretreatment agent in the first embodiment.
[0028] The viscosity of the pretreatment agent in the first embodiment is not particularly limited and may be set appropriately depending on the dosage form used. When the dosage form of the pretreatment agent in the first embodiment is liquid, it may be, for example, 1000 mPa·s or less. When the dosage form of the pretreatment agent in the first embodiment is cream, a viscosity of 6000 mPa·s to 30000 mPa·s is preferable, 8000 mPa·s to 20000 mPa·s is preferable, and 9000 mPa·s to 12000 mPa·s is more preferable in order to prevent it from running off the hair. A viscosity of 6000 mPa·s or more can suppress it from running off the hair, and a viscosity of 30000 mPa·s or less makes it easy to apply to the hair surface. The viscosity is determined by using a B-type viscometer (such as the TOKIMEC B-type viscometer "VISCOMETER TV-20") and the value after 60 seconds at 25°C using a rotor selected according to the viscosity.
[0029] The pretreatment agent of the first embodiment has a pH of 2.5 to 8.5 at 25°C, preferably 3.0 to 6.5. A pH of 2.5 or higher minimizes the impact on the skin, and a pH of 8.5 or lower reduces the risk of hair damage. The above pH values can be obtained by measuring the pretreatment agent of the first embodiment at 25°C using a known pH meter.
[0030] The pretreatment agent of the first embodiment can be manufactured by a known method for manufacturing a permanent wave pretreatment agent, depending on the dosage form used.
[0031] (Permanent wave solution 1) The pretreatment agent of the first embodiment can be used by applying it to the hair before treatment with Permanent Wave Solution 1.
[0032] This permanent wave solution contains a reducing agent. Examples of reducing agents include known reducing agents having a thiol group, such as thioglycolic acid, thioglycolate salts (ammonium thioglycolate, monoethanolamine thioglycolate, etc.), cysteamine, cysteamine salts (cysteamine hydrochloride, etc.), cysteine (L-cysteine, DL-cysteine, etc.), cysteine salts (L-cysteine hydrochloride, DL-cysteine hydrochloride, etc.), acetylcysteine (N-acetyl-L-cysteine, etc.), glyceryl thioglycolate, thiolactic acid, thiolactic acid salt, and butyrolactone thiol. The amount of reducing agent in the permanent wave solution is, for example, 2% by mass or more and 15% by mass or less.
[0033] Permanent wave solution 1 may contain one or more alkaline agents to adjust the pH to the alkaline side. Examples of these alkaline agents include ammonia, amino alcohols (monoethanolamine, triethanolamine, isopropanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, etc.), basic amino acids (arginine, etc.), morpholine, carbonates (ammonium carbonate, ammonium bicarbonate, sodium carbonate, sodium bicarbonate, etc.), phosphates (ammonium monohydrogen phosphate, sodium monohydrogen phosphate, etc.), and caustic alkalis (potassium hydroxide, sodium hydroxide).
[0034] In addition to the above, Permanent Wave Solution 1 may also contain nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, polymer compounds, silicones, hydrocarbons, waxes, higher alcohols, polyhydric alcohols, fatty acids, oils and fats, ester oils, proteins, amino acids, anti-inflammatory agents, preservatives, chelating agents, fragrances, and more.
[0035] When water is included in the Permanent Wave Solution 1, the amount of water included is, for example, 60% by mass or more.
[0036] As the nonionic surfactant, the same type as that described for the pretreatment agent in the first embodiment can be incorporated in the same proportion.
[0037] As for the polyhydric alcohol, the same type as that described for the pretreatment agent in the first embodiment can be blended in a similar proportion.
[0038] Examples of chelating agents include EDTA, EDTA salts (disodium EDTA, trisodium EDTA, tetrasodium EDTA, dipotassium EDTA, etc.), diethylenetriaminepentaacetic acid, diethylenetriaminepentaacetic acid salt (pentasodium diethylenetriaminepentaacetic acid, etc.), ethylenediaminehydroxyethyl triacetic acid, ethylenediaminehydroxyethyl triacetate salt (trisodium ethylenediaminehydroxyethyl triacetate, etc.), hydroxyethanediphosphonic acid, hydroxyethanediphosphonic acid salt (tetrasodium hydroxyethanediphosphonic acid, etc.). The amount of chelating agent may be, for example, 0.01% by mass or more and 2% by mass or less, 0.05% by mass or more and 1% by mass or less, or 0.1% by mass or more and 0.5% by mass or less.
[0039] The form of the Permanent Wave Solution 1 used is not particularly limited and can be liquid, cream, or gel. However, a liquid form is preferred for Permanent Wave Solution 1 because it is easier to apply evenly to the hair.
[0040] The viscosity of the Permanent Wave Solution 1 is not particularly limited and should be set appropriately according to the formulation used. When the Permanent Wave Solution 1 is used in liquid form, for example, it may be 1000 mPa·s or less. When the Permanent Wave Solution 1 is used in cream form, to prevent it from running off the hair, a viscosity of 2000 mPa·s or more is good, 4000 mPa·s or more is preferable, 8000 mPa·s or more is more preferable, and 10000 mPa·s or more is even more preferable. Furthermore, to improve the penetration of the Solution 1 into the hair, a viscosity of 30000 mPa·s or less is good, 25000 mPa·s or less is preferable, and 20000 mPa·s or less is more preferable. The viscosity is measured at 25°C for 60 seconds using a B-type viscometer (such as the TOKIMEC VISCOMETER TV-20) with a rotor selected according to the viscosity, and the value adopted is taken.
[0041] The pH of the Permanent Wave 1 solution at 25°C is preferably between 4.0 and 10.0, and more preferably between 6.0 and 9.0. A pH of 4.0 or higher is excellent for wave formation in the permanent wave, while a pH of 10.0 or lower reduces the risk of hair damage. The above pH values can be obtained by measuring the pH of the Permanent Wave 1 solution at 25°C using a known pH meter.
[0042] Furthermore, from the viewpoint of improving the persistence of the waves in the permanent wave, it is preferable that the pH of at least one of the pretreatment agent and the permanent wave agent 1 of the first embodiment is 7.0 or higher. In particular, it is more preferable that the pH of the permanent wave agent 1 is higher than the pH of the pretreatment agent of the first embodiment, and among these, it is even more preferable that the pH of the permanent wave agent 1 is 8.0 or higher, and among these, it is even more preferable that the pH of the pretreatment agent of the first embodiment is 7.5 or higher.
[0043] Permanent wave solution 1 can be manufactured by a known method for manufacturing permanent wave solution 1, depending on the dosage form used.
[0044] After treatment with Permanent Wave Solution 1, it is preferable to either perform treatment with Permanent Wave Solution 2 or oxidize the hair with air, from the viewpoint of achieving excellent wave formation while reducing the risk of hair damage, and it is more preferable to perform treatment with Permanent Wave Solution 2.
[0045] (Permanent wave solution 2) The second component of a permanent wave treatment, for example, contains an oxidizing agent.
[0046] The oxidizing agent included in the Permanent Wave 2 solution is preferably a bromate salt (such as sodium bromate or potassium bromate) or hydrogen peroxide, similar to known Permanent Wave 2 solutions.
[0047] Furthermore, the Permanent Wave 2nd Agent may contain additional ingredients that are commonly found in known Permanent Wave 2nd Agents, such as nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, polymer compounds, silicones, hydrocarbons, waxes, higher alcohols, polyhydric alcohols, fatty acids, oils and fats, ester oils, proteins, amino acids, chelating agents, anti-inflammatory agents, preservatives, and fragrances.
[0048] When water is included in the Permanent Wave 2nd Solution, the amount of water included is, for example, 70% by mass or more.
[0049] The type of formulation used when applying the second solution for permanent waves is not particularly limited and may include, for example, liquid, cream, or foam.
[0050] The pH of the Permanent Wave Developer 2, when containing bromate, is, for example, between 5.0 and 9.0 at 25°C. Furthermore, the pH of the Permanent Wave Developer 2, when containing hydrogen peroxide, is, for example, between 2.5 and 3.5 at 25°C.
[0051] Permanent wave developer 2 can be manufactured using a known method for manufacturing permanent wave developer 2, depending on the dosage form used.
[0052] After the treatment using the Permanent Wave Agent 1 described above, and before the treatment using the Permanent Wave Agent 2 described above, an intermediate treatment agent may be used. The intermediate treatment agent is not particularly limited, and for example, the same as the pretreatment agent of the first embodiment may be used, or a pretreatment agent that does not contain chicoriic acid, gallic acid, tannic acid, tyriloside, or echinacoside as in the pretreatment agent of the first embodiment may be used.
[0053] After the treatment using the Permanent Wave 2 agent, a post-treatment agent may be used. The post-treatment agent is not particularly limited; for example, the same agent as the pre-treatment agent in the first embodiment may be used, or an agent that does not contain chicoriic acid, gallic acid, tannic acid, tyriloside, or echinacoside may be used.
[0054] (Permanent wave method) In the permanent wave method using the pretreatment agent of the first embodiment, the pretreatment agent of the first embodiment is applied to the hair.
[0055] In this permanent wave method, for example, the pretreatment agent of the first embodiment may be applied to hair wrapped around a predetermined rod, and then left in that state at a predetermined temperature such as room temperature for a predetermined time of about 5 to 15 minutes.
[0056] After the pretreatment agent of the first embodiment has been applied to the hair and left to stand, it is preferable to apply the Permanent Wave 1 agent to the hair without rinsing off the pretreatment agent of the first embodiment, in order to allow sufficient polyphenols such as chicoric acid contained in the pretreatment agent to remain in the hair. With the Permanent Wave 1 agent applied to the hair, it is preferable to leave it at a predetermined temperature such as room temperature for a predetermined time of about 5 to 30 minutes, in order to achieve excellent wave formation of the permanent wave while reducing the risk of hair damage.
[0057] After the Permanent Wave Solution 1 has been applied to the hair and left to stand, it is preferable to rinse the hair with water, towel dry it, and then apply the Permanent Wave Solution 2 to the hair, in order to reduce the risk of hair damage. With the Permanent Wave Solution 2 applied to the hair, it is preferable to leave it at a predetermined temperature such as room temperature for a predetermined time of about 5 to 30 minutes, in order to allow for good oxidation of the hair while reducing the risk of hair damage.
[0058] Furthermore, after the treatment using the Permanent Wave 1 agent has been performed, but before the treatment using the Permanent Wave 2 agent has been performed, the intermediate treatment agent may be used in addition. Also, after the treatment using the Permanent Wave 2 agent has been performed, the post-treatment agent may be used in addition.

[0073] (Permanent wave method) In the permanent wave method using the first agent of the second embodiment, the first agent of the second embodiment is applied to the hair.
[0074] In this permanent wave method, a permanent wave solution is applied to the hair wrapped around a predetermined rod, and it is preferable to leave it in that state for a predetermined time of about 5 to 30 minutes at a predetermined temperature such as room temperature, from the viewpoint of achieving excellent wave formation while reducing the risk of hair damage.
[0075] In this permanent wave method, before the treatment using Agent 1 of the second embodiment, the permanent wave pretreatment agent is applied to the hair, and from the viewpoint of ensuring that polyphenols such as chicoric acid contained in the pretreatment agent remain sufficiently in the hair, it is preferable to leave the permanent wave pretreatment agent at a predetermined temperature such as room temperature for a predetermined time of about 5 to 30 minutes without rinsing it off.
[0076] After the first agent of the second embodiment has been applied to the hair and left to stand, from the viewpoint of reducing the risk of hair damage, it is preferable to wash the hair with water, towel dry it, and then apply the second permanent wave agent to the hair. With the second permanent wave agent applied to the hair, from the viewpoint of reducing the risk of hair damage while ensuring good oxidation of the hair, it is preferable to leave it at a predetermined temperature such as room temperature for a predetermined time of about 5 to 30 minutes.
[0077] Furthermore, after the treatment using the first agent of the second embodiment has been performed, but before the treatment using the second permanent wave agent has been performed, the treatment using the intermediate treatment agent may be performed. Also, after the treatment using the second permanent wave agent has been performed, the treatment using the post-treatment agent may be performed. [Examples]
[0078] The present invention will be described in detail below with reference to examples, but the present invention should not be interpreted as being limited based on the description of these examples.
[0079] Formulations A1-A21, B1-B20, and C1-C2, described below, were manufactured, and permanent wave treatments for each experiment were performed using the examples and comparative examples, which are combinations of each formulation, and the results were evaluated.
[0080] In Tables 1 to 9, the units of the values in the ingredient column are w / v%, and the amount that results in pH ○.○ of phosphoric acid or ammonia water is the amount that results in the pH (25°C) value indicated in each formulation. In the purified water column, "amount that totals 100" means that the total amount of water is added to the total amount of the other components that make up each formulation to make 100 w / v%. Also, in "Polyoxyethylene cetyl ether (30 E.O.)" listed in Tables 1 to 9, "30 E.O." means that the average number of moles of ethylene oxide added is 30.

[0090] (Examples 1a-1e, Comparative Example 1a) Experiment 1-1 was conducted for Examples 1a-1e and Comparative Example 1a, using formulations A1-A6 as pre-treatment agents for permanent waves, respectively.
[0091] <Experiment 1-1> Hair bundles used: Multiple bundles of 30cm long, 10g heavy black human hair (product number: BS-B3A) manufactured by Beaulux Co., Ltd. were used, cut to a length of 23cm and with 50 strands each. Permanent wave treatment: The following treatment was performed on the hair strands used above. 2 mL of any of the formulations A1 to A6 (permanent wave pre-treatment agents) was applied to a single strand of hair wrapped around a 1.12 mm diameter rod, and left at room temperature for 10 minutes. 2. Apply 2 mL of Formula B6 (Permanent Wave Solution 1) to one strand of hair wrapped around a rod, and leave at room temperature for 20 minutes. 3. Afterwards, the hair bundle was rinsed with tap water for 60 seconds. 4. Next, after lightly towel-drying the hair, 2 mL of Formula C2 (Permanent Wave Solution 2) was applied to each strand of hair and left at room temperature for 20 minutes. 5. Remove the hair bundles from the rods, rinse them with water, and while still wet, hang them vertically on the board with the ends of the hair facing downwards, and air dry them. 6. The air-dried hair strands were washed with Milbon Grand Linkage Willow Luxe Shampoo and rinsed with water (this procedure was repeated 14 times to simulate the persistence of the waves after two weeks). 7. With the hair bundles still wet, the bundles were suspended vertically and attached to the board with the ends of the hair facing downwards. 8. Using wet hair strands, the total length (mm) was measured and the setting rate was calculated as shown below, followed by the calculation of the setting rate divided by the total length.
[0092] Method of measuring total length (mm): A bundle of hair was attached to a board with markings, and the markings were measured visually. Calculation Method for Set Rate (Method for Measuring Rotation Speed): To evaluate the wave-forming force on permanent wave-treated hair under each processing condition, the set rate in bending and setting was calculated according to Wortmann's report. The set rate was calculated by taking permanent wave-treated hair, floating it in purified water, measuring the diameter d (mm) of the circle formed by the hair, and calculating the set rate S (%) using the following formula. Here, d0 is the diameter of the rod (mm). S(%) = d0 / d × 100
[0093] Experiment 1-1 was performed twice, and the average value (N=2) was calculated from the total length and set rate values obtained in each experiment. Next, the set rate / total length (set rate (N=2) ÷ total length (N=2)) value was calculated. A higher set rate / total length value indicates better wave retention in permanent waves.

[0096] (Examples 1f-1g, Comparative Examples 1a-1e) Experiments 1-2 were conducted for Examples 1f-1e and Comparative Examples 1a-1e, where formulations A6-A12 were used as pre-treatment agents for permanent waves, respectively.
[0097] <Experiment 1-2> Using hair bundles from a different lot, the procedure was the same as in Experiment 1-1, except that step 1 was modified as follows. 2 mL of one of the formulations A6 to A12 (permanent wave pre-treatment agent) was applied to a single strand of hair wrapped around a 1.12 mm diameter rod, and left at room temperature for 10 minutes.

Furthermore, even when polyphenols were incorporated into the permanent wave pretreatment agent, in the case of polyphenols such as caffeoyl glucose, quercetin, fukinolic acid, and rosmarinic acid, the set rate / total length worsened compared to Comparative Example 1a, which did not contain polyphenols (see Table 11, Comparative Examples 1a-1e).
