Description

Pharmaceutics and methods of perm

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

In general, the perm treatment is performed by first cutting a cystine bond in the hair with a first agent containing a reducing agent, and then reforming the second zero cystine bond containing an oxidizing agent (Patent Document 1). . Here, as the oxidizing agent, there are two types, one containing bromate (cancellate) as a main component and one containing hydrogen peroxide as a main component. (Patent Document 1) Japanese Patent Application Laid-Open No. 5-97635

By the way, hydrogen peroxide has a strong oxidation effect and can be shortened the treatment time because of its immediate effect, while the stimulation to the hair is strong, causing cracks in the hair after treatment, and the treatment tends to be uneven. Have a drawback.

On the other hand, since bromate has a slower oxidation compared to hydrogen peroxide, the hair has a small irritation while the treatment time tends to be long, thereby impairing the patient long-term patience. In addition, since the treatment time is long, the hair is exposed to the drug for a long time, and thus, the advantage of less irritation cannot be fully utilized, and the hair tends to be damaged.

The present invention has been completed based on the above-described matters, and an object thereof is to provide a perm agent and a perm method which can reduce damage to hair and are easy to use.

The present inventors have studied diligently to develop a perm and a method of perm that can reduce hair damage, and surprisingly, by using a mixture of hydrogen peroxide and bromate as an oxidant, the defects of each other are compensated for. It has been found that the damage of the hair can be suppressed to a minimum thereby, and the present invention has been completed.

That is, the perm agent of this invention contains the 1st agent which has a reducing agent and an alkali agent as a main component, the 2nd agent which has hydrogen peroxide as a main component, and the 3rd agent which has bromate as a main component.

In addition, the perm 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 second agent mainly containing hydrogen peroxide and bromate after the first treatment step. The second treatment step of treating the hair is performed by a mixed solution of a third agent.

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

Moreover, in this invention, it is preferable to process a hair by the 5th agent which has glyoxylate aldehyde as a main component after the process by a 2nd agent and a 3rd agent. Accordingly, since agents such as a reducing agent and an oxidant adhered to the hair are completely removed, the damage to the hair caused by these agents remaining in the hair can be reduced. In addition, the cystine bonds reformed by the oxidizing agent are further strengthened, so that the wave can be kept long.

In addition, the perm agent of this invention contains the 1st agent which has a reducing agent and an alkali agent as a main component, the 2nd agent which has hydrogen peroxide as a main component, and the 3rd agent which has bromate as a main component.

The first agent contains a reducing agent and an alkali agent as main components. Here, the reducing agent is not particularly limited as long as it is commonly used as a reducing agent for perm, and for example, cysteines such as thioglycolate salts such as ammonium thioglycolic acid and thioglycolic acid monoethanolamine, cysteine, cysteine hydrochloride, and N-acetyl cysteine Derivatives and cysteamine derivatives can be used. The alkali agent is not particularly limited as long as it is usually used as an alkali agent for a perm, and for example, ammonia water, monoethanolamine and triethanolamine can be used. Moreover, the 1st agent may contain various subcomponents normally used as a perm agent, such as a stabilizer, a cream base, an emulsifier, antioxidant, a fragrance | flavor, as needed.

The second agent mainly contains 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 subcomponents commonly used as perm agents, such as stabilizers and pH adjusters, as necessary.

The third agent contains bromate as an oxidizing agent as a main component. As bromate, what is normally used as an oxidant for a perm may be used, for example, sodium bromide, potassium bromide, etc. can be used. The concentration of bromate is preferably about 2.5 to 3.5% by weight. If necessary, the third agent may contain various subcomponents commonly used as perm agents such as stabilizers and pH adjusters.

In addition, the perm agent of this invention may contain the 4th agent and 5th agent described below.

The fourth agent contains a treatment oil agent as a main component. Treatment agents are used in combination with oxidizing agents to penetrate the hair to restore damage, to impart softness and elasticity. There is no restriction | limiting in particular as this treatment agent, if it has a treatment effect without breaking the combined effect of hydrogen peroxide and bromate which are oxidizing agents. For example, mink oil, meadowfoam oil, collagen, cetanol, lanolin, mineral oil, oleic acid, oleic acid sorbitan, sesquioleic acid sorbitan, hydroxy stearic acid, stearic acid, rosin acid, dipentaerythritol, sorbic acid Glyceryl tee (TEA), sodium phosphate, stear trimonium chloride, cetrimonium chloride, lauryl trimonium chloride, dicodimonium chloride, oleth-4, oleth-5, oleth-7, oleth-15 , oleth-20, amodimethicone, oleyl alcohol, phosphoric acid, methyl paraben, propyl paraben and the like can be used. If necessary, the fifth agent may contain various subcomponents used in ordinary perm agents such as emulsifiers, stabilizers and pH adjusters.

The fifth agent is a rinse agent mainly containing glyoxyl aldehyde. Glyoxyl aldehyde has the effect of removing the reducing agent remaining in the hair, strengthening the cystine bond, and the like. The 5th agent may contain various subcomponents used for normal perm, such as a stabilizer, a preservative, a pH adjuster, and surfactant as needed.

Hereinafter, the method of performing a perm using the perm agent of this invention is demonstrated.

First, a part of the first agent is applied to the hair of the shampooed subject. Next, after winding the hair after application | coating to a rod, the remaining 1st agent is apply | coated and it is left to stand for 15 to 20 minutes (1st process process). At this time, the treatment time can be shortened by capping the head of the subject as needed and applying a temperature.

When the first treatment step is finished, the hair is washed with warm water while being wound on the rod, and then the moisture is wiped off. Next, the second agent, the third agent, and the fourth agent are mixed to adjust the mixed liquid. There is no restriction | limiting in particular in the mixing order of these 3 types of drugs. In addition, although three kinds of chemical mixing amounts are made into the same quantity by principle, it is more preferable to adjust according to the hair condition of a subject and the desired hairstyle. Next, the appropriate amount of the mixed solution is applied to the hair of the subject as it is while the rod is wound. Thereafter, it is left to stand for 5 to 10 minutes (second treatment step). In addition, the second, third, and fourth agents require mixing immediately before use.

At this time, since the stimulation to the hair by the oxidant becomes milder than when using hydrogen peroxide alone, damage to the hair is reduced. In addition, since the treatment time is shorter than when bromate is used alone, the procedure can be performed without requiring the patient for a long time, and at the same time, it is possible to suppress the occurrence of damage caused by exposure of the hair to irritation for a long time. In addition, since the mixed solution contains a fourth agent including a treatment oil, the treatment oil penetrates into the hair during the treatment, and damaged hair is recovered to impart softness and elasticity to the hair.

When the first treatment step is completed, the fifth agent is sprayed on the hair as it is wound on the rod (third treatment step). Accordingly, the agent remaining in the hair is washed. Thereby, the bad influence, such as damage to the hair by a residual chemical | medical agent, can be prevented. In addition, since a thio compound, especially used as a reducing agent, often has an unpleasant odor for a subject, washing well with a fifth agent is very effective for removing the odor from the hair.

Next, rinse with water while lightly massaging the entire hair. Finally, the rod is removed from the hair and dried with a dryer to complete the whole process.

In addition, in the present Example, although the 4th agent containing a treatment oil agent and the 5th agent containing glyoxyl aldehyde were used, according to this invention, one or both of 4th agent, 5th agent is not used. You don't have to. In the case where the fourth agent is not used, the mixing amount of the second agent and the third agent in the second treatment step may be the same amount in principle, but it is preferable to adjust in consideration of the hair condition of the subject, the desired hairstyle, and the like. In addition, the second agent and the third agent are required to be mixed immediately before use.

(In addition, if the fifth agent is not used, after the end of the second treatment step, the agent may be washed by a method usually performed by a perm treatment.)

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

Table 8 shows the evaluation of hair damage, elasticity, gloss, touch, and perm odor after treatment in each example and comparative example. In addition, elasticity, glossiness, and touch were evaluated in the following four steps.

◎: Very good ○: Good △: Not very good X: Not good

Hair damage elasticity burnish touch After-treatment Example 1 none ◎ ◎ ◎ None at all Example 2 none ○ ◎ ○ None at all Example 3 none ◎ ◎ ◎ None at all Comparative Example 1 has exist △ X X Many Comparative Example 2 has exist X X X has exist

"Elasticity", "gloss" and "feel" were evaluated in the following four steps.

◎: Very good ○: Good △: Not very good X: Not good

In Table 1, in Examples 1, 2, and 3, no damage was observed to the hair after the perm treatment, and there was no odor that was a perm smell. Moreover, elasticity, gloss, and a touch were all favorable. In addition, in the comparative example in which bromate is used alone as an oxidant and at the same time a combination of the fifth agent for washing the agent after treatment with the fourth agent using the treatment oil agent is observed, hair is damaged after perm treatment. Was confirmed. In addition, elasticity, gloss, and touch were not all satisfactory.

Table 9 shows the measurement results of the breaking strength, the hair content, and the coefficient of friction in the examples and the comparative examples.

Breaking strength (g) Hair function amount (% by weight) Coefficient of friction Example 1 155 13 0.28 Example 2 160 14 0.19 Example 3 145 13 0.2 Comparative Example 1 105 9 0.34 Comparative Example 2 98 7 0.37

In Table 9, with respect to the breaking strength, in Examples 1 to 3, it is 145g to 155g, and is within a range that can be said to be almost healthy hair. On the other hand, in Comparative Example 1 and Comparative Example 2, it is 105g and 98g, and it can be said that intensity | strength fell as a result of hair damage by a perm treatment.

Regarding the hair moisture content, it is 13%-14% in Examples 1-3 and it exists in the range which can be called almost healthy hair. On the other hand, in Comparative Example 1 and Comparative Example 2, it is 9% and 7%, and it can be said that moisture is lost as a result of damaging the hair by the perm treatment.

Regarding the friction coefficient, in Examples 1 to 3, it was 0.19 to 0.28, and the slip performance was good. On the other hand, in Comparative Example 1 and Comparative Example 2, it is 0.34 and 0.37. As a result, the cuticle on the surface is damaged by the perm treatment, and the slip property is deteriorated.

Therefore, according to the perm of the present invention and the method of perm using the same, it can be seen that hair damage can be avoided.

According to this invention, the 2nd agent containing hydrogen peroxide and the 3rd agent containing bromate are mixed and used as an oxidizing agent. In this way, since the stimulation to the hair by the oxidant becomes milder than when using hydrogen peroxide alone, damage to the hair is reduced. In addition, since the treatment time can be shorter than when bromate is used alone, the procedure can be performed without forcing the patient to be patient for a long time, and the occurrence of damage due to exposure of the hair to the drug for a long time can be suppressed. As such, hydrogen peroxide and bromate supplement the defects while taking advantage of each other, thereby minimizing damage to the hair, and providing a perm and perm method that can be easily used.
