Description

[Detailed description of the invention]

[Technical Field] This invention relates to a rinse agent for cold permanent waves. [Background Art] Permanent wave treatment is performed using a first agent that is a solution of a reducing agent and a second agent that is a solution of an oxidizing agent. As the reducing agent of the first agent, thioglycolic acid or its salt, or cysteine is used,
Furthermore, in order to make the reducing power effective, the pH is adjusted to 8.0 to 10.0 using an organic alkaline agent such as ammonia or ethanolamine as a hair swelling agent. As the second agent, sodium bromate is mainly used. The second agent requires not only oxidizing power but also the ability to neutralize as much as possible the residual alkali used in the first agent. This is because, if such ability is lacking, the residual alkali will cause secondary damage to the hair after the perm treatment. In addition, it is preferable to add an organic acid to the second agent in order to remove bad odors such as mercaptan, ammonia, hydrogen sulfide, etc. generated by hair swelling and reduction, and to increase the durability of the wave.
For this reason, an organic acid is added to the second agent, an aqueous solution of sodium bromate, to adjust the pH to 5.0, which is said to be the isoelectric point of hair.
It is desirable to adjust to ~6.0. however,
Setting the pH of the sodium bromate aqueous solution to an acidic range as described above impairs the long-term stability of the solution, and may cause off-odor generation and discoloration. Furthermore, water-soluble polypeptides and amino acids, which prevent hair damage and improve hair curl and texture, are also undesirable in the second agent because they tend to change during long-term storage. Furthermore, during treatment with the second agent, the second agent hangs down from the head, causing problems such as getting into the eyes of the patient, staining his clothes, and causing discomfort. [Object of the invention] In view of the above, this invention eliminates dripping of the second agent during treatment with the second agent, removes bad odors,
The purpose of the present invention is to provide a powder rinse agent for permanent waves that improves the durability of the waves, and improves the length and feel of the waves. [Disclosure of the Invention] In order to achieve the above object, the present invention comprises sodium bicarbonate and/or potassium bicarbonate, an organic acid, and a powdered water-soluble polypeptide, and a first agent and a second agent for permanent waving. Its gist is a powdered foaming rinse agent for perms that is used for treatment between agents (between the first agent and second agent) and/or for addition to the second agent immediately before using the second agent. . This invention will be explained in detail below. From now on, wt% will be simply written as %. Sodium hydrogen carbonate and potassium hydrogen carbonate are added to generate carbon dioxide gas and cause foaming. Carbon dioxide gas generated from sodium bicarbonate and potassium bicarbonate forms bubbles and covers the hair. This can prevent the second agent from dripping. moreover,
The carbon dioxide gas allows the second agent to penetrate well into the hair, increasing the effect (oxidizing power) of the second agent, and the carbon dioxide bubbles envelop foreign odors, making the deodorizing effect remarkable. Note that both of these may be used alone or in combination. The organic acid is used to neutralize the alkaline agent in the first agent, remove bad odors (such as ammonia odor), and improve the durability and texture of the waves. Various organic acids can be used, including tartaric acid, malic acid, citric acid, and succinic acid. Powdered water-soluble polypeptide is added to improve hair texture and texture, and to maintain foam. The powdered water-soluble polypeptide used in the rinse agent of this invention is a collagen hydrolyzate, and has a molecular weight of 1,000 to 30,000 using a proprietary technology.
(preferably 1,000 to 15,000) obtained by spray drying several types of aqueous solutions. The blending amounts of sodium bicarbonate and/or potassium bicarbonate, organic acid, and powdered water-soluble polypeptide are not particularly limited, but the weight ratio of sodium bicarbonate and/or potassium bicarbonate to powdered water-soluble polypeptide is 1.50 or more. and the weight ratio of organic acid to powdered water-soluble polypeptide is preferably 2.00 or more. Other amino acids, sucrose, sucrose ester,
Alternatively, powdered fragrances, wetting agents, penetrants, emulsifiers,
A dye or the like may be added in an amount that does not impair the purpose of the invention. Amino acids are added to improve the strength and texture of the hair. Examples of amino acids include aspartic acid, glutamic acid, threonine, methionine, serine, and arginine among acidic, neutral, and basic amino acids. Or there is a complex. It is preferable that 2 g to 10 g of the powder rinse agent of the present invention be dissolved in 100 ml of water or a second agent, and in this case, the pH of the solution is 4.0 to 6.0. However, the amount added is not limited to this. The powder rinse agent of the present invention is dissolved alone in water in an appropriate proportion and used as an intermediate rinse agent between the first and second permanent wave treatments. Alternatively, it can be added directly to the second agent at an appropriate ratio immediately before use, and the pH is 4.0.
It may be used adjusted to ~6.0. in this case,
This is preferable because it does not change the sodium bromate of the second agent in any way, and rather saves time and effort.
Another method is to use it as an after-rinse. That is, the powder rinse agent is used after applying the first agent, washing with water, and the second agent in this order. In this case, the swelling and reduction with the first agent restores and protects damaged hair and more effectively neutralizes it. The powder rinse agent of the present invention is usually obtained by powdering the above-mentioned ingredients and then mixing them, but this is not always necessary, and sodium bicarbonate and/or potassium bicarbonate, organic acid , and powdered water-soluble polypeptide are prepared separately in powder form and mixed for the first time in water or a second agent at the time of use, and their forms vary. In order to examine the effects of the rinse agent of this invention, the following experiments were conducted using the following formulations. (Prescription) As the first permanent wave agent, it was formulated as follows and the pH was adjusted to 9.3. Ammonium thioglycolate (50%)...12.0% Strong ammonia water...2.5% Emulsified oil agent...1.0% Purified water...84.5% (Formulation) As a permanent wave second agent, mix as follows and adjust the pH with sodium citrate. Adjusted to 6.5. Sodium bromate...6.0% Emulsified oil agent...1.0% Purified water...93.0% (Formulation) As an example of the powder rinse agent of the present invention, the following compounding ratio was used. Sodium hydrogen carbonate...33.0 parts Tartaric acid...47.0 parts Powdered water-soluble polypeptide...20.0 parts (A) PH test 3 g of prescription mixed with 100 ml of water and prescription (second agent)
Table 1 shows the change in pH over time when each was added to 100 ml.

[Table] Next, an alkali residual test and a wave efficiency test were conducted according to the following treatment examples. (Treatment example 1) After applying the first prescribed agent, perform an intermediate wash with a 3% aqueous solution of the prescribed rinse agent, and then apply the prescribed second agent. (Treatment example 2) After applying the first part of the prescription, apply the second part of the prescription to which 3% of the prescribed powder rinse agent has been added. (Comparative treatment example 1) As a conventional treatment example, the prescribed first agent is treated, and then the prescribed second agent is treated. This will be referred to as Comparative Treatment Example 1. (B) Alkali Residuality Test According to the operations and treatments of Treatment Examples 1 and 2 and Comparative Treatment Example 1, specifically, the alkali residual property of hair after perming was examined as shown below. -Specific example 1 based on treatment example 1- 1 g of the same person's hair, approximately 15 cm long, was tied into a bundle and immersed in 10 ml of the first agent (at 25°C) for 15 minutes.
Next, wash off the first agent with 40ml of distilled water,
Add 100ml of a 3% aqueous solution of the prescribed rinse agent (at 25°C)
Soaked for 15 minutes. After that, 10ml of the second dose of the prescription
(25°C) for 10 minutes, then thoroughly rinsed with 40 ml of distilled water, and the hair tresses were centrifuged for 10 minutes. -Specific example 2 based on treatment example 2- Similarly to specific example 1, the same person's hair strands were treated with the first agent and washed with water, then 10ml of the prescribed second agent added with 3% of the prescribed rinse agent. (25℃) to 10
Soaked for minutes. Then, the hair was thoroughly rinsed with 40 ml of distilled water, and the hair bundle was centrifuged for 10 minutes. -Specific Example Based on Comparative Treatment Example 1- In the same manner as in Specific Example 1, hair strands of the same person were treated with the first agent and washed with water. Thereafter, the sample was treated with the second agent in the same manner as in Example 1 without being treated with a rinsing agent, washed with water, and then centrifuged. Add 40ml of distilled water to each hair strand treated above.
ml (30°C) for 1 hour, and then filtered with suction.
The same operation was repeated a total of 5 times for each hair bundle to obtain about 200 ml of filtrate. These filtrates
The alkaline residual properties were determined by titration with 0.1N HCl using the following formula and are shown in Table 2. Alkali residual property = T/F x H However, T: Number of ml of 0.1N-HCl F: Number of ml of filtrate (extracted water) H: Number of grams of hair

[Table] (C) Wave efficiency (wave forming ability and wave persistence) test Using the waving agent and rinse agent of the formulation,
The following treatment examples 1 and 2 and comparative treatment example 1 were performed and the wave forming ability was examined. The wave forming ability was evaluated by the diameter of the curl of naturally dried hair after the perm treatment. - Specific example 1 based on treatment example 1 - Approximately 1 g of hair from the same person with a length of approximately 15 cm was bundled, and the diameter
The tube was wound around a 10 mm plastic rod, the first agent was sufficiently applied thereto, the tube was left at room temperature for 15 minutes, and then washed with water. Then wash with water with a 3% aqueous solution of the prescribed rinse agent. Next, the second agent was applied sufficiently, and after being left at room temperature for 10 minutes, the hair bundle was removed from the rod, washed with water, and air-dried. I measured the diameter of the curl of this hair bundle. This was repeated three times and the values obtained are shown in Table 3. -Specific Example 2 based on Treatment Example 2- Similarly to Specific Example 1, a bundle of hair from the same person was rolled into a rod, treated with the first agent, and washed with water. Next, 3% of the prescribed rinse agent was added to the second agent, and the solution was applied to the hair bundle wound into a rod and left at room temperature for 10 minutes. Thereafter, the hair bundle was removed from the rod, treated in the same manner as in Example 1, and the diameter of the curl was measured. This was done three times and the results are shown in Table 3. -Specific example based on comparative treatment example 1- Similarly to specific example 1, a bundle of hair from the same person was rolled into a rod, treated with the first agent, and washed with water. Next, without treating with a rinse agent, the second agent was treated in the same manner as in Example 1, and the diameter of the curl was measured. This was done three times and the results are shown in Table 3.

[Table] After measuring the above-mentioned wave forming power, each hair was examined for wave durability. Each of these hair bundles was immersed in 5% sodium lauryl sulfate (50°C) and stirred for 30 minutes. Next, the hair bundle was taken out, thoroughly washed with running water, and air-dried.
The diameter of each curl was measured for the hair bundles of each of these examples. This was done three times each, and the results are shown in Table 4.

[Table] As shown in Tables 3 and 4, when the rinse agent of the present invention is used, the wave forming ability and wave sustainability are improved. This is because the second agent penetrates the hair well due to the carbon dioxide gas generated from the rinse agent, increasing its effect (oxidizing power).
Therefore, in terms of this effect, it is more preferable to use the rinse agent of the present invention dissolved in a second agent than to dissolve it in water and use it alone. (D) Odor removal effect test Thirty beauticians detected the presence or absence of odor while applying the second agent in Treatment Examples 1 and 2 and Comparative Treatment Example 1 of the wave efficiency test in (C). did. The results are shown in Table 5.

[Table] As shown in Table 5, the use of the rinse agent of the present invention greatly increases the deodorizing effect. This is because carbon dioxide bubbles generated from the rinse agent cover the hair, and carbon dioxide gas and organic acids combine with ammonia and the like. Whether the rinse agent is dissolved in water and used alone or dissolved in a second agent, there is no major difference in the effect, but the latter is preferred because it is slightly better. (E) Texture Test Thirty hairdressers judged the texture and feel of each hair after wave sustainability was measured in Test (C). The results are shown in Table 6.

[Table] As shown in Table 6, using the rinse agent of the present invention improves the texture of the hair. this is,
This is the effect of polypeptides in rinse agents. This effect can be seen whether the rinse agent is dissolved in water and used alone or dissolved in a second agent, but the latter case is preferable because it is slightly better. As is clear from the above experimental results, the use of the rinse agent of the present invention did not reduce the performance of the second perm agent, but rather enhanced its effectiveness. Next, we will show an experiment to see the effect of powdered water-soluble polypeptide. (F) Foaming Test For the rinse agent of this invention, a solution of 0.45 g of powdered water-soluble polypeptide added in advance to 100 ml of water was mixed with sodium bicarbonate and an organic acid (tartaric acid). The formulations were varied as shown in Table 7, and the foaming properties were evaluated as follows and are shown in Table 8. ◎…Good ○…Fair △…Slightly bad

〔Effect of the invention〕

The powder rinse agent of this invention contains sodium bicarbonate and/or potassium bicarbonate, an organic acid, and a powdered water-soluble polypeptide, so this rinse agent can be dissolved alone in water after the first permanent wave treatment. If it is used by directly dissolving in a second agent, carbon dioxide bubbles are generated, and the bubbles are retained by the polypeptide. Therefore, dripping of the second agent can be prevented. Also,
Bad odors can be removed by carbon dioxide bubbles and organic acids. Furthermore, it improves the frizz and texture of the hair, and also helps to enhance the effect of the second agent.
