Abstract

PROBLEM TO BE SOLVED: To solve such a problem that when hair-protecting processing is made with a conventional pretreatment agent and a wave is formed with a perm 1 agent and a perm 2 agent, whether a weaker wave is formed depends on the concentration of an alkali agent or reducing agent or the excessive action of the agent makes the hair frizzy, as the damage of the hair becomes larger, to make adequate processing very difficult, and consequently a wave which a customer wants is nearly impossible to form in an on-the-spot hair salon.SOLUTION: There are provided an agent for permanent waves in which a desired, beautiful and elastic wave can be formed to the hair which receives very large damage, such as high-bleach hair and frizzy-cured hair, the wave being very difficult to form until now, and a method for permanent waving.

Description

  The present invention relates to a cross-linking permanent agent and a cross-linking permanent method.

  Hereinafter, a conventional example will be described while explaining the present invention.

  The first agent is mainly composed of a reducing agent. Any reducing agent may be used as long as it is normally used as a permanent reducing agent. For example, thioglycolates such as ammonium thioglycolate and monoethanolamine thioglycolate, cysteine derivatives such as cysteine and cysteine hydrochloride, and cysteamine derivatives can be used. The concentration of ammonium alkali thioglycolate is 2 to 14 parts by weight, and the other reducing agent is preferably 2 to 14 parts by weight in terms of ammonium thioglycolate. The presence or absence of alkali is not questioned.

  The second agent is not particularly limited as long as it is normally used as an oxidizing agent for permanents as an oxidizing agent. For example, hydrogen peroxide and bromate can be used.

  The third agent was made 100 parts by weight by adding 2 to 10 parts by weight of an acrylic resin alkanolamine, 0.05 parts by weight of methylparaben, and purified water. The acrylic resin alkanolamine penetrates into the hair together with the first agent, and becomes a raw material that crosslinks to the hollow portion of the porous hair. Furthermore, it adsorbs to the peeled part of the cuticle and gives gloss, smoothness, and flexibility.

  The fourth agent consists of 2-8 parts by weight of glyoxylaldehyde, 0.5 parts by weight of citric acid, 0.5 parts by weight of sodium citrate, and 0.2 parts by weight of amphoteric surfactant (cocamidopropyl Betaine) or nonionic activator (polyoxyethylene lauryl ether, polyoxypropylene lauryl ether), 0.05 parts by weight of dipotassium glycyrrhizinate, 0.05 parts by weight of methylparaben, and 100 parts by weight of purified water It was. Glyoxylaldehyde crosslinks the third acryl resin alkanolamine in the hair, strengthens the keratin protein, and recombines the open cystine by the oxidation reaction, thereby forming a strong wave.

In general, permanent treatment involves applying a pretreatment agent to protect large damaged parts such as the hair ends, cutting the cystine bond in the hair with a first agent containing a reducing agent, and then containing an oxidizing agent. This is performed by rebinding the cystine bond cleaved by the second agent (Patent Document 1).
Japanese Patent Laid-Open No. 5-97635

  When the hair protection treatment with the conventional pre-treatment agent and wave formation with one perm and two permanents, the wave formation is too weak or excessive depending on the concentration of alkaline agent and reducing agent as the hair damage increases. As a result, proper processing was very difficult, and the wave formation desired by the customer was almost impossible in the beauty salon at the site.

  The present invention has been solved on the basis of the above-described circumstances, and it has been desired that a desired beautiful and elastic wave can be applied to extremely damaged hair such as hybrid hair and straight hair which has been extremely difficult. An object of the present invention is to provide a permanent agent and a permanent method that can be formed.

Further, because of the crosslinking effect, the wave forming treatment time can be shortened compared with the case where only the reducing agent is used, so that the treatment can be performed without imposing physical burden on the subject.

  The permanent wave agent of the present invention is a first agent mainly composed of a reducing agent, regardless of the presence or absence of alkali. Furthermore, it includes a second agent mainly composed of an oxidizing agent, a third agent mainly composed of an acrylic resin alkanolamine, and a fourth agent mainly composed of glyoxylaldehyde.

  The first agent is mainly composed of a reducing agent. Any reducing agent may be used as long as it is normally used as a permanent reducing agent. For example, thioglycolates such as ammonium thioglycolate and monoethanolamine thioglycolate, cysteine derivatives such as cysteine and cysteine hydrochloride, and cysteamine derivatives can be used. The concentration of ammonium alkali thioglycolate is 2 to 14 parts by weight, and the other reducing agent is preferably 2 to 14 parts by weight in terms of ammonium thioglycolate.

Acrylic resin alkanolamine, and if necessary, methylparaben, together with the first agent, penetrates into the hair and becomes a raw material that crosslinks into the cavity of the porous hair. Furthermore, it adsorbs to the peeled part of the cuticle and gives gloss, smoothness, and flexibility.

  The fourth agent consists of 2-8 parts by weight of glyoxylaldehyde, 0.5 parts by weight of citric acid, 0.5 parts by weight of sodium citrate, and 0.2 parts by weight of amphoteric surfactant (cocamidopropyl Betaine) or nonionic activator (polyoxyethylene lauryl ether, polyoxypropylene lauryl ether), 0.05 parts by weight of dipotassium glycyrrhizinate, 0.05 parts by weight of methylparaben, and 100 parts by weight of purified water It was. Glyoxylaldehyde crosslinks the third acryl resin alkanolamine in the hair to bond main chains such as keratin and recombine side chains of cystine opened by oxidation reaction to form strong waves Is done.

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

  A liquid mixture of the first agent and the third agent (mixing ratio 1: 2 to 5: 1), preferably 1: 1, is preferably applied to the subject's hair, and the applied hair is wound around a rod. The remaining liquid is applied again and left for 5 to 15 minutes (first treatment step). In principle, the mixing ratio of the first agent and the third agent may be equal, but it is preferable to adjust the reducing power according to the hair quality and damage degree of the person to be treated. At this time, it is possible to shorten the treatment time by heating at 40 to 60 ° C. for 5 to 10 minutes using a heating device.

  Alternatively, the first agent is applied to the hair of the person to be treated, and the hair is softened by leaving or heating for 5 to 15 minutes without being wound on the rod, and then washed with water, and then the third agent is applied to the hair. Roll into the rod and leave for 10-20 minutes. Alternatively, the processing time can be shortened by heating at 40 to 60 ° C. for 5 to 10 minutes using a heating device (first processing step).

  At this time, compared with the case where the first agent, which is a reducing agent, is used alone, it does not act excessively on the hydrophilic part, and it acts gently on the hair and protects it so that it is embedded in the cavity part. Is greatly reduced.

  When the first treatment step is completed, a mixed solution of the second agent and the fourth agent (mixing ratio 1: 2 to 1: 1) is applied and left for 5 to 10 minutes (second treatment step). In principle, the mixing ratio of the second agent and the fourth agent may be equal, but when the second agent is bromate, it is better to mix with the fourth agent immediately before use. In this case, only the fourth agent may be used without mixing with the second agent. Under the present circumstances, it can also heat for 5 to 10 minutes at 40-60 degreeC using a heating apparatus, and can shorten processing time and can accelerate | stimulate a crosslinking action.

  At this time, compared with the case where the conventional second agent is used alone, the mixed use of the second agent and the fourth agent is the use of the acrylic resin alkanolamine and the fourth agent contained in the third agent in the first step. The glyoxylaldehyde contained causes a synergistic effect of the cross-linking reaction and exerts a great effect on hair elasticity and wave formation. In particular, it is effective for damaged hair with a lot of soft hair, fine hair and β-keratin. Furthermore, the acrylic resin alkanolamine attached to the surface of the hair protects instead of the peeled or rough hair epidermis and imparts gloss, suppleness and smoothness. And the protective effect is continued for a long time by the crosslinking effect.

  When the second treatment step is completed, the rod is removed from the hair and a mixed solution of the third agent and the fourth agent is applied (third treatment step). Thereby, the bad influence of the chemical | medical agent remaining on hair is prevented and the further crosslinking effect can be anticipated.

  Next, the hair is sufficiently washed with water and dried with a dryer or the like to complete the whole process.

  In the second step, the second agent and the fourth agent are mixed and used, but according to the present invention, only the fourth agent may be used. When the second agent is not used, the concentration of glyoxylaldehyde of the fourth agent is preferably about 4% by weight in the second treatment step.

  Hereinafter, an example is given and the details of the present invention are explained.

Treatment result 1

  From the treatment result 1, in the wet state of the example, the wave shape after the permanent treatment is clean and undisturbed, and the wave efficiency is 2.5 times the rod diameter. On the other hand, in the wet state of the comparative example using the first agent as the reducing agent and the second agent alone as the oxidizing agent, the wave shape after the permanent treatment is disturbed, and the wave efficiency is twice the rod diameter. And wrinkles were more likely to occur on the cuticle.

Treatment result 2

  From the treatment result 2, when the hair is dry, the shape of the wave after the permanent treatment is clean, and particularly, there is no flickering of the hair tip. On the other hand, in the dry state of the comparative example in which the first agent as the reducing agent and the second agent as the oxidizing agent were used alone, the wave shape after the permanent treatment was not settled, and particularly satisfied with the dustiness of the hair tips. It wasn't going.

  From the above, it has been found that the permanent agent of the present invention and the permanent method using the same can satisfactorily form a wave even in hair that is difficult by conventional methods and avoid damage.

  Each example described above shows a preferable example, and a permanent agent having the same effects and features and a permanent method using the same are within the scope of the present invention.
