Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a first permanent wave agent for iron perms.

[0002]

2. Description of the Related Art A conventional iron perm treatment method generally used in barber shops is as follows. First, the disulfide contained in the hair keratin is swelled with a first agent containing a reducing agent such as ammonium thioglycolate or monoethanolamine thioglycolate and an alkaline agent such as ammonia or monoethanolamine, and then swelling the hair. Break the bond. Next, the first agent is rinsed with water or slightly warm water, and then a hair protecting agent containing mineral oil or vegetable oil as a main component is applied to the hair in order to prevent the hair from being damaged by the heat of the iron. After that, about 100 to 18
The desired curl is formed by heat denaturing the hair keratin with an iron for ironing perm heated to 0 ° C. Finally, in order to oxidatively fix the curl, a second layer mainly composed of an oxidizing agent such as sodium bromate is used.
The agent is applied to obtain a permanent curl.

[0003]

Conventionally, in order to prevent damage to the hair due to the heat of the iron and to conduct the heat of the iron uniformly to the hair before ironing the hair in this way, liquid paraffin is used. A liquid, paste or solid hair protective agent containing oils and fats such as castor oil or olive oil as a main component is applied to hair. However, it is troublesome to apply a hair protectant, and it is very difficult to apply an appropriate amount to the entire hair uniformly and easily for ironing, and it has been a barber's experience in many cases. Furthermore, this operation is also uncomfortable for the subject. Further, during ironing, if an excessive amount of a hair protecting agent is applied on the hair, the iron slips too much and the tension is not applied well, which inevitably increases the time required for the ironing operation. On the other hand, when the amount of the hair protecting agent is too small, there is a problem that the iron slips badly and is difficult to operate, and also the hair is considerably damaged.

[0004]

Therefore, the present inventor can omit the process of applying a hair protecting agent by blending a hydrocarbon in the first agent for iron perm, and the above-mentioned problems are basically solved. I was able to solve it.

Examples of hydrocarbons used in the present invention include liquid paraffin, petrolatum, paraffin, ceresin, squalane, squalene, liquid polyisobutylene, isoparaffin, liquid isoparaffin, microcrystalline wax, pristane and the like. The first agent for iron perm, which is a mixture of one or more of these, is applied to the hair, then washed with water, and the moisture is wiped off with a towel or the like, after which the hair is in a dry state. Therefore, it is easy to apply tension when ironing, and the amount of smoke generated is small. In this way, since an even amount of hydrocarbons remain evenly on the hair before the ironing operation,
There is no need to apply a hair protectant again. Among these, liquid paraffin, liquid polyisobutylene and squalane are preferable. Of these, squalane is particularly preferable. The blending amount is 5 to 30% (Wt / V)
Is optimal, and if less than 5% (Wt / V),
The amount of hydrocarbons remaining on the hair after washing off the agent is reduced and the iron slips poorly, which makes it difficult to operate the iron, and the hair is greatly damaged by the heat of the iron. Dust and dryness occur. Further, when it exceeds 30% (Wt / V),
Since the hydrocarbons excessively remain on the hair after the first agent is washed off, the iron slips too much, tension is not applied properly, and the ironing operation takes a long time. Further, the finish is not preferable because the hair has a sticky feel.

The first agent for iron perms of the present invention usually contains a reducing agent and an alkaline agent. As a reducing agent,
Mercapto compounds, thioglycolic acid, ammonium thioglycolate, sodium thioglycolate,
Thioglycolate salts such as monoethanolamine thioglycolate, cysteine and its hydrochloride, N-acetyl-L-cysteine and the like can be mentioned. Among these, thioglycolic acid and thioglycolic acid salts are preferable.

The second agent used after the first agent for iron perm of the present invention is the same as the second agent for ordinary permanent waves, and as the oxidizer, sodium bromate, potassium bromate and the like are used. Bromate, hydrogen peroxide,
1 to 20% by weight of perborate or the like is blended.

The method of applying an iron perm using the first agent for iron perm of the present invention is as follows. First,
The first agent for iron perm of the present invention is applied to hair, combed through to be evenly applied to hair, and allowed to stand for 5 to 20 minutes, and then rinsed with water or slightly warm water. After that, the curl is formed by using an iron for an iron perm heated to about 100 ° C to 180 ° C. Then, apply a second agent composed of an oxidizing agent such as sodium bromate to
After leaving it for 20 minutes, rinse with water or lukewarm water. Conventionally, before performing an ironing operation, in order to prevent damage to the hair due to heat of the iron, an operation of applying a hair protective agent containing a mineral oil or a vegetable oil as a main component to the hair has been performed. The operation can be made unnecessary.
Therefore, the ironing operation can be performed more easily than in the conventional method, and the treatment time can be shortened by about 15 to 20 minutes. Also, no smoke is generated during the ironing operation. Then, a uniform curl can be obtained without damaging the hair.
