Abstract

<P>PROBLEM TO BE SOLVED: To provide a permanent wave agent decreasing damage of hair and easily usable, and to provide a permanent-waving method. <P>SOLUTION: The permanent wave agent is used with a second agent containing hydrogen peroxide and a third agent containing a bromate salt as oxidizers. Thereby, as the irritation on the hair due to the oxidizer is moderated than that of hydrogen peroxide single use so the damage caused on the hair is decreased. And, as the treating time can be shortened than that of bromate salt single use, so treatment can be performed without forcing long time endurance to a subject and occurrence of damage caused by hair exposure to chemicals is suppressed. A forth agent composed mainly of a treatment oil agent is preferably used therewith. And, after treatment using the first agent/second agent and the third agent, a fifth agent composed mainly of glyoxylaldehyde and for removing remaining oxidizers and reductants is preferably used. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a permanent agent and a permanent method.

In general, the permanent treatment is performed by first cutting the cystine bond in the hair with the first agent containing the reducing agent and then re-forming the cystine bond with the second agent containing the oxidizing agent (Patent Document 1). . Here, there are two types of oxidizing agents: those containing bromate as a main component and those containing hydrogen peroxide as a main component.
Japanese Patent Laid-Open No. 5-97635

  However, since hydrogen peroxide has a strong oxidizing action and has an immediate effect, the treatment time can be shortened, but the stimulation to the hair is strong, and the hair after treatment is squeaked, and the treatment is uneven. There are drawbacks such as being easy to be.

  On the other hand, bromate has a mild oxidative effect compared to hydrogen peroxide, so it is less irritating to hair, but has the disadvantage of forcing patient to endure for a long time while tending to take longer treatment time. . In addition, since the treatment time is long, the hair is exposed to the drug for a long time, and eventually the advantage that the irritation is small is not fully utilized and the hair tends to be damaged.

  The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a permanent agent and a permanent method that can reduce hair damage and are easy to use.

  The inventors of the present invention have intensively studied to develop a permanent agent and a permanent method capable of reducing hair damage, and surprisingly use a mixture of hydrogen peroxide and bromate as an oxidizing agent. As a result, it was found that each other's drawbacks were compensated, and that hair damage could be minimized, and the present invention was completed.

  That is, the permanent agent of the present invention includes a first agent mainly composed of a reducing agent and an alkali agent, a second agent mainly composed of hydrogen peroxide, a third agent mainly composed of bromate, Is included. Further, the permanent method of the present invention includes a first treatment step of treating hair with a first agent mainly comprising a reducing agent and an alkali agent, and a first treatment step comprising hydrogen peroxide as a main component after the first treatment step. And a second treatment step of treating the hair with a mixed liquid obtained by mixing two agents and a third agent containing bromate as a main component.

  In this invention, it is more preferable to mix the 4th agent which has a treatment oil agent as a main component with the 2nd agent and the 3rd agent. By infiltrating the treatment oil into the hair, damaged hair is repaired, and softness and flexibility are imparted to the hair.

  In the present invention, after the treatment with the second agent and the third agent, it is preferable to treat the hair with the fifth agent containing glyoxylaldehyde as a main component. Thereby, since chemical | medical agents, such as a reducing agent and an oxidizing agent adhering to hair, are removed completely, the damage to the hair by these chemical | medical agents remaining in hair can be reduced. In addition, since the cystine bond reformed by the oxidizing agent is further strengthened, the wave can be prolonged.

  According to the present invention, the second agent containing hydrogen peroxide as the oxidizing agent and the third agent containing bromate are mixed and used. In this way, the hair is irritated by the oxidizing agent more slowly than when hydrogen peroxide is used alone, so that damage to the hair is reduced. In addition, since the treatment time can be shortened compared to when bromate is used alone, the treatment can be performed without forcing the patient to be patient for a long time, and the hair can be used for a long time. Generation of damage due to exposure can be suppressed. In this way, hydrogen peroxide and bromate make use of each other's advantages and make up for the drawbacks, so that hair damage can be minimized, and an easy-to-use permanent agent and method can be provided. .

  The permanent agent of the present invention includes a first agent mainly composed of a reducing agent and an alkali agent, a second agent mainly composed of hydrogen peroxide, and a third agent mainly composed of bromate. It is a waste.

  The first agent is mainly composed of a reducing agent and an alkali agent. Here, the reducing agent is not particularly limited as long as it is normally used as a permanent reducing agent. For example, thioglycolates such as ammonium thioglycolate and monoethanolamine thioglycolate, cysteine, cysteine hydrochloride Cysteine derivatives such as salt / N-acetylcysteine and cysteamine derivatives can be used. The alkali agent is not particularly limited as long as it is usually used as an alkaline agent for permanents. For example, aqueous ammonia, monoethanolamine, or triethanolamine can be used. Moreover, the 1st agent may contain the various subcomponents normally used for permanent agents, such as a stabilizer, a cream base, an emulsifier, antioxidant, a fragrance | flavor, as needed.

  The second agent is mainly composed of hydrogen peroxide as an oxidizing agent. The concentration of hydrogen peroxide is preferably about 2 to 3% by weight. The second agent may contain various auxiliary components that are usually used as permanent agents, such as stabilizers and pH adjusters, as necessary.

  The third agent is mainly composed of bromate as an oxidizing agent. Any bromate may be used as long as it is a normal oxidizing agent. For example, sodium bromate, potassium bromate and the like can be used. The bromate concentration is preferably about 2.5-3.5 wt%. The third agent may contain various auxiliary components that are usually used as permanent agents, such as stabilizers and pH adjusters, as necessary.

  The permanent agent of the present invention may further contain a fourth agent and a fifth agent described below.

  The fourth agent is mainly composed of a treatment oil agent. The treatment agent is used together with an oxidant, and penetrates into the hair to repair damage and impart softness and flexibility. The treatment agent is not particularly limited as long as it does not impair the combined effect of the oxidizing agent hydrogen peroxide solution and bromate and has a treatment effect. For example, mink oil, meadow foam oil, collagen , Cetanol, lanolin, mineral oil, oleic acid, sorbitan oleate, sorbitan sesquioleate, hydroxystearic acid, stearic acid, rosin acid, dipentaerythrityl, sorbic acid, glyceryl dimaleate TEA, sodium phosphate, steartrimonium chloride, spine Trimonium chloride, lauryltrimonium chloride, dicocodimonium chloride, oleth-4, oleth-5, oleth-7, oleth-15, oleth-20, amodimethicone, oleyl alcohol, phosphoric acid, methylparaben, propyl The Raven and the like can be used. The fifth agent may contain various auxiliary components that are usually used as permanent agents, such as emulsifiers, stabilizers, pH adjusters, and the like as necessary.

  The fifth agent is a rinse agent mainly composed of glyoxylaldehyde. Glyoxylaldehyde has actions such as removal of a reducing agent remaining on the hair and strengthening of cystine bond. The fifth agent may contain various auxiliary components that are usually used as permanent agents, such as stabilizers, preservatives, pH adjusters, and surfactants, as necessary.

  Hereinafter, a method for performing permanent treatment using the permanent agent of the present invention will be described.

  First, a part of 1st agent is apply | coated to the hair of the to-be-treated person. Next, after the applied hair is wound around the rod, the remaining first agent is applied and left for 15 to 20 minutes (first treatment step). At this time, if necessary, the treatment time can be shortened by covering the head of the patient with a cap and performing heating.

  When the first treatment step is completed, the hair is rinsed off with hot water while being wound around the rod, and then moisture is wiped off. Next, the second agent, the third agent, and the fourth agent are mixed to prepare a mixed solution. There are no particular restrictions on the order of mixing these three drugs. In addition, the mixing amount of the three kinds of drugs may be equal in principle, but is more preferably adjusted according to the hair quality of the person to be treated, the target hair style, and the like. Next, an appropriate amount of the mixed solution is applied to the hair of the subject while the rod is wound. Then, it is left for 5 to 10 minutes (second processing step). In addition, it is necessary to mix the 2nd agent, the 3rd agent, and the 4th agent immediately before use.

  At this time, since the stimulation to the hair by the oxidizing agent is moderate as compared with the case where hydrogen peroxide is used alone, damage to the hair is reduced. In addition, since the treatment time is shorter than when bromate is used alone, the treatment can be performed without forcing the patient to endure for a long time, and the hair is exposed to the drug for a long time. Occurrence of damage caused by this can be suppressed. Furthermore, since the mixture contains a fourth agent containing a treatment oil agent, this treatment oil agent penetrates into the hair during treatment, repairs damaged hair, and gives the hair a softness and flexibility. The

  When the first treatment step is completed, the fifth agent is thoroughly sprinkled on the hair while being wound around the rod (third treatment step). Thereby, the drug remaining on the hair is washed away. Thereby, adverse effects such as hair damage caused by the remaining drug can be prevented. In particular, many thio compounds used as a reducing agent have an unpleasant odor for the person to be treated. Therefore, it is very effective to remove the odor from the hair by thoroughly washing with the fifth agent.

  Next, the hair is rinsed with water while gently rubbing it. Finally, the rod is removed from the hair and dried with a dryer or the like to complete the entire process.

In this embodiment, the fourth agent containing the treatment oil agent and the fifth agent containing glyoxylaldehyde are used. However, according to the present invention, one or both of the fourth agent and the fifth agent are not used. May be. When the 4th agent is not used, the mixing amount of the 2nd agent and the 3rd agent may be equal in principle in the second treatment process, but the hair quality of the person to be treated, the desired hair style, etc. are considered. It is preferable to adjust. Moreover, it is necessary to mix the second agent and the third agent immediately before use.
Further, when the fifth agent is not used, after the second treatment step, the medicine may be washed away by a method that is normally performed in the permanent treatment.

  Hereinafter, the present invention will be described in more detail with reference to examples.

[Results and discussion]
The formulations of the first agent, the second agent, the third agent, the fourth agent, and the fifth agent in each example are shown in Table 1, Table 2, Table 3, Table 4, and Table 5, respectively. Tables 6 and 7 show the composition of the first agent and the second agent in each comparative example.

Table 8 shows the evaluation of hair damage, elasticity, gloss, touch, and residual odor after treatment in each of Examples and Comparative Examples. “Hari Koshi”, “Glossy”, and “Tactile sensation” were evaluated according to the following four levels.
Very good ○: Moderately good △: Not very good ×: Not good

  From Table 8, in Examples 1, 2, and 3, no damage was visually recognized on the hair after permanent treatment, and there was no residual odor. In addition, “Hari Koshi”, “Glossy” and “Tactile” were all good. On the other hand, in the comparative example using bromate alone as the oxidizing agent and not using the fourth agent using the treatment oil agent and the fifth agent for washing away the agent after treatment, Damage to the hair was observed and a residual odor was observed. Also, “Hari Koshi”, “Tsuya” and “Tactile sensation” were not satisfactory.

  Table 9 shows the measurement results of the breaking strength, hair moisture content, and coefficient of friction in each Example and Comparative Example.

  From Table 9, regarding break strength, it was 145g-155g in the thing of Example 1-Example 3, and it was in the range which can be said to be almost healthy hair. On the other hand, it is 105g and 98g in the thing of the comparative example 1 and the comparative example 2, and it can be said that intensity | strength fell as a result of the hair being damaged by the permanent treatment.

  Regarding the moisture content of the hair, it was 13% to 14% in Examples 1 to 3, and was within a range that could be said to be almost healthy hair. On the other hand, those of Comparative Example 1 and Comparative Example 2 are 9% and 7%, and it can be said that moisture was lost as a result of the hair being damaged by the permanent treatment.

  Regarding the coefficient of friction, those of Examples 1 to 3 were 0.19 to 0.28, and the slipperiness was good. On the other hand, in Comparative Example 1 and Comparative Example 2, they are 0.34 and 0.37, and it can be said that the slipperiness is reduced as a result of the cuticle on the surface being damaged by the permanent treatment.

  From the above, it was found that hair damage can be avoided by the permanent agent of the present invention and the permanent method using the same.
