DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waving lotion and a method of using the same, and more particularly to a novel waving lotion based on elucidation of the relationship between a thickening and spreading agent which is an important additive of the waving lotion and the waving lotion for each application. The present invention relates to a waving lotion and a treatment method using the same.

[0002]

2. Description of the Related Art Although the theory of permanent waves has not been sufficiently elucidated, cystine bonds (-SS-) in hair play an important role. Usually, the first liquid (so-called waving lotion) and the second liquid are used for the permanent wave, and the first liquid contains thioglycolic acid or a salt thereof or cysteine as a reducing agent as an alkaline solution. The moisture, alkali and reducing agent in the first liquid break hydrogen bonds, salt bonds and cystine bonds in the hair, respectively, and soften the hair. As the oxidizing agent, potassium bromate, sodium bromate, sodium perborate, and four kinds of hydrogen peroxide are recognized as the oxidizing agent, and sodium bromate is usually used. After the first solution is applied, it is rinsed off with an acidic rinse, and when the second solution is applied, the alkali is neutralized and the salt bond is recombined. The cystine bond is recombined by the action of the oxidizing agent, and as the hair dries, A new hydrogen bond is also completed, creating a wave on the hair.

[0003] The function and quality required of the first liquid are primarily reducing power, but there are a lot of other incidentally necessary conditions, in which a thickening and spreading agent is given. The impact is very large. The main purpose of the addition of the thickener is to give the first liquid an appropriate viscosity and spreadability.

[0004] Conventionally used thickening agents include cellulose derivatives, sodium polyacrylate, polyisobutylene, polyethylene glycol, polyvinyl alcohol, natural pastes and the like. Also,
JP-A-61-286312 discloses that a carboxymethylcellulose salt having a degree of etherification (hereinafter abbreviated as DS) of 2.0 or more is used as a thickening and spreading agent. However, waving lotion has a wide variety of uses, and the viscosity, function,
The physical properties are different, and ingenuity is required for the usage of the thickener according to each usage or application. JP-A-61-2863
No. 12 merely discloses that a carboxymethylcellulose salt having a degree of etherification (hereinafter abbreviated as DS) of 2.0 or more is used as a thickening and spreading agent.

[0005]

Various functions, properties and qualities are required for the thickening and spreading agent of waving lotion. Although the degree of use varies depending on the method of use and application, problems that often occur include, when evaluated as a waving lotion solution, long-term function / quality stability, reducing power, appropriate viscosity and favorable fluidity and uniformity. It has spreadability, hair affinity, high transparency, dispersion stability promoting effect, low temperature curlability, rinsing effect, etc., and easy dissolving work of the thickening spreader during production of waving lotion is also important.
However, a waving lotion that solves all of the above-mentioned problems has not been obtained by conventional techniques.

When viewed by application of waving lotion, a waving lotion for cold wave is subjected to a reducing step and an oxidizing step in a state in which hair is wound around a rod. Easy rinsing of intermediate water and acidic rinse is particularly required. Waving lotion for iron perm is required to reduce curl at low temperature, fluidity with moderate viscosity, curability at low temperature, especially curling with iron after reducing hair evenly and uniformly with lotion solution Is done.
Also, since the waving lotion for curly hair straightening needs to be reduced to keep the curly hair in a straight hair state, a high viscosity such that a hair bundle is formed at the time of applying the first liquid, curling is prevented and a straight hair state is obtained, It is required to have high tackiness and to be able to spread more than the other two types, and to spread uniformly.

[0007]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that by using an alkali metal salt or ammonium salt of carboxymethylcellulose having a DS of 2.0 or more and adjusting the viscosity during use to a specific range, Finding that a waving lotion for cold wave, iron perm, and hair straightening that satisfies all of the above issues can be obtained,
The present invention has been completed.

[0008] The present invention, DS is an alkali metal salt or ammonium salt of 2.0 or more carboxymethylcellulose as increasing Nebaten Chakuzai, viscosity is 3~1000cps in liquid temperature 25 ° C., the liquid temperature 50 ° C. 2.5 cold waving waving lotion, characterized in that the range of ～350Cps, DS is an alkali metal salt or ammonium salt of 2.0 or more carboxymethylcellulose as increasing Nebaten Chakuzai, viscosity is in the liquid temperature 25 ° C. 700 ~ 30000cps ,
Containing iron perm waving lotion, characterized in that the liquid temperature 50 ° C. in the range of 220～12000Cps, and DS the alkali metal salt or ammonium salt of 2.0 or more carboxymethylcellulose as increasing Nebaten Chakuzai, viscosity Is in the range of 7,000 to 60,000 cps at a liquid temperature of 25 ° C., and a curving straightening waving lotion, and various treatment methods using these waving lotions.

In the case of a waving lotion for a cold wave, the hair is wound around a rod and subjected to a reducing step and an oxidizing step, so that it has smooth fluidity and affinity for hair, and is easy to wash with intermediate water and acid rinse. Is particularly required. In the present invention, the viscosity of the waving lotion is 3 to 1000 cps when the liquid temperature is 25 ° C, and when the liquid temperature is 50 ° C.
If an alkali metal salt or ammonium salt of carboxymethyl cellulose having a DS of 2.0 or more is added so as to be 2.5 to 350 cps, a waving lotion for a cold wave satisfying all the above requirements can be obtained. As a method of performing a cold wave using this cold wave waving lotion, in a so-called lot winding method in which the hair is wound using a lot, in a so-called lot winding method, the waving lotion is applied to the hair that has been subjected to winding by a water roll in advance. There is a method of applying the process and keeping the process time for 10 to 15 minutes. In addition, the waving lotion for cold wave of the present invention,
It is also possible to use for so-called iron winding method in which hair is wound by an ironing operation. In this case, the process is performed by a method in which the process time is set to 10 to 15 minutes. Conventionally, treatment of cold wave by iron winding method is not performed,
The treatment can be performed only by using the waving lotion according to the present invention.

[0010] In the case of a waving lotion for an iron perm, it is particularly required that the waving lotion has an appropriate viscosity, has an affinity for hair, and can be curled at a low temperature. In the present invention, the viscosity of the waving lotion is 25
700 ~ 30000 cps at ℃, 220 ~ 1 at 50 ℃
If an alkali metal salt or ammonium salt of carboxymethylcellulose having a DS of 2.0 or more is added so as to be 2000 cps, a suitable waving lotion for an iron perm can be obtained. In the case of using the conventional product, the temperature is from 180 to 240 ° C., but according to the waving lotion for an iron perm of the present invention, it is 80 to 170 ° C., so that the hair is not damaged by heat. As a treatment method of the iron perm using the waving lotion for the iron perm, the surface temperature of the iron is set to 80 to 170 ° C, preferably 100 to 140 ° C using the waving lotion.
In addition, there is a method in which the ironing operation is performed by setting the ironing operation time to 8 to 25 minutes. Also, the waving lotion is originally for iron perm, but after applying the waving lotion to the hair and leaving the process time for 8 to 15 minutes, straightening the curly hair using an iron As a result, an excellent curly hair straightening effect is exhibited, so that it can be suitably used for hair straightening treatment.

[0011] In the case of a waving lotion for curly hair straightening, it is important that the spreading amount can be increased and the spread is uniform, and further, a hair bundle is formed when the first liquid is applied.
A lotion solution that prevents curling and forms a straight hair state is ideal. If an alkali metal salt or an ammonium salt of carboxymethyl cellulose having a DS of 2.0 or more is used as a thickening spreader and the viscosity of the lotion solution is adjusted as follows, a waving lotion for curly hair that satisfies the above requirements can be obtained. . The viscosity here is 7000 to 60,000 cps at a liquid temperature of 25 ° C. and 3200 to 39000 cps at a liquid temperature of 50 ° C. As a treatment method for hair straightening using this waving lotion for hair straightening, without applying a pretreatment related to hair straightening, the waving lotion application time is 8 to 15 minutes, and the process time is 10 to 15 minutes. Method. After applying the waving lotion to the hair and leaving the process time for 8 to 15 minutes,
It can also be used in a hair straightening treatment method that straightens hair using an iron at -170 ° C.

The alkali metal salt of carboxymethylcellulose used in the waving lotion of the present invention includes lithium salt, potassium salt, sodium salt and the like. Among them, sodium salt which is industrially widely produced is most commonly used. Is done.

In the present invention, as components other than the thickening and spreading agent of the waving lotion, components usually used in the waving lotion for each application can be appropriately used.

[0014]

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

Examples 1 to 6 A commercially available cold wave waving lotion was used as a stock solution, and Ernest Gum FDM was used as a thickening and spreading agent.

Undiluted solution: Cadas Beauty Wave N / F 2-bath cold solution ... for hard hair Manufacturer: Wella Japan Co., Ltd. Distributor: Cadas Cosmetics Co., Ltd.

[0016]

[Table 1]

The amount added is the amount of Ernest Gum FDM per 100 g of the stock solution. The viscosity was measured at 25 ° C. using a Brookfield B-type viscometer.

The waving lotions shown in Table 1 were evaluated for practical use according to the following methods in accordance with the respective applications. 1) Evaluation of cold wave A barber A (male 40 years old) and a barber B (female 35 years old) were given a model of 10 persons each, and cold wave treatment was performed using the waving lotion solutions of Examples 1 and 2. . The evaluation results were as follows. (1) Since it has a suitable adhesiveness and affinity for hair, there was no dripping on the background and no damage to the background. (2) Since the hair was evenly applied to the hair, the reduction time was reduced by about 20% compared to the conventional method. (3) The combing after the completion was very good, and a rinsing effect was observed. (4) The waving lotion according to the present invention remained unchanged in pH, viscosity, transparency, color tone, dispersion state, hair reducing power, etc. for two years under normal storage conditions (room temperature standing in a closed container not exposed to sunlight). . 2) Evaluation of iron perm A barber A (male 40 years old) and a barber B (female 35 years old) were given models of 10 persons each, and were subjected to iron perm using the waving lotion solutions of Examples 3 and 4. . The evaluation results were as follows. (1) The same effect as the above cold wave was observed. (2) Low-temperature curl becomes possible, and curl temperature is
The temperature could be lowered by 70-100 ° C, and the heat damage to the hair was completely eliminated. 3) Hair straightening evaluation Barber A (male 40 years old) and barber B (female 35 years old) are given a model of 10 persons each, and hair straightening is performed using the waving lotion solutions of Examples 5 and 6. I let it. The evaluation results were as follows. (1) Despite being a high-viscosity liquid, it has an appropriate fluidity and has an affinity for hair, so it does not lump like conventional products, it spreads evenly, and it was possible to increase the spread amount . (2) The condition of the subsequent process became milder to form a hair bundle at the time of applying the first liquid and to promote a straight hair state. (3) Observation over time after the treatment showed that there was almost no re-curly hair. (4) Good storage stability similar to the above was observed. On the other hand, when the undiluted solution is used, in any case, the viscosity is too rough without any viscosity, so that the absolute amount of spreading is too small and the reduction is insufficient or poor, and the object is not achieved.

Application of oxidizing agent (second agent) Apply the cream of the second agent with the hair reduced and leave the process time for 10 to 20 minutes in the straight hair state. V. Rinsing Acid Rinse (Treatment) Follow the usual method VI. Aftercut According to the wishes of the model, cut the hair by setting the length and amount of hair, taking into account the volume, hair flow, etc. Next, in order to compose the entire style, the volume, the hair flow and the curl state of the hair are set and cut. [Evaluation Results] A model in which re-curling was observed was considerably observed. The hair was dusty. The operation time was 2 to 3.5 hours, the productivity did not increase, and the model was tired.

Example 12 <Evaluation of hair straightening: iron straight method> A barber A (male 40 years old) and a barber B (female 35 years old) were given 10 models each, and the waving of Examples 5 and 6 was performed. Using a lotion solution, hair straightening by the iron straight method was performed by the following method and evaluated. [Treatment method (conditions)] I. Pre-care Hair diagnosis Follow the usual method Pre-shampoo Follow the usual method II. Set the hair style Follow the usual method III. Drying Stop the treatment with a little damp enough to apply the first agent. IV. Applying the reducing agent (first agent) Apply the first agent to the hair (the amount of the first agent is about 50 ~
100 ml / person). First agent process time 8-15 minutes At the end of the process time, rinse with slightly warm water,
Drop the first agent. Towel dry Wipe off the moisture from the root to the tip of the hair. Apply treatment oil Apply evenly so that the iron slides well and is easy to operate. V. Ironing operation At the lowest possible temperature (130-160 ° C), apply heat so that the hair can be straightened quickly. Based on the setting of the hairstyle, the hair straightening iron is operated in 10-30 minutes. Avoid prolonged heating and use at high temperatures. VI. Apply oxidizing agent (second agent) Follow the usual method of straightening hair VII. Follow the usual method of rinsing and acid rinsing (treatment) VIII. Aftercut length according to the model's request, taking into account volume, hair flow, etc. , Set the amount and cut. Next, in order to compose the whole style, the hair is cut while observing the curl state. IX. Hair Restoring Agent Follow the usual method [Evaluation Results] There was no dripping on the scalp and no damage to the scalp due to appropriate adhesiveness and affinity for hair.
Despite being a high-viscosity liquid, it has an appropriate fluidity, and has an affinity for hair, so that it does not lump as in the conventional product, uniform spreading was achieved, and the spreading amount could be increased.
In order to form a hair bundle at the time of application of the first agent and promote a straight hair state, the conditions in the post-process became milder. After the operation,
When observed over time, there was almost no re-curly hair. Since it was applied to the hair with a uniform viscosity and straightened with an iron, the treatment time was reduced by 20 to 90 minutes compared to the conventional curly hair straightening method, and the reduction time was reduced by about 20% compared to the conventional method. After the reducing agent was washed away, the hair was straightened with an iron. However, the hair was set straight according to the hair design settings, and the straight perm was beautifully finished. The hair was not damaged because the iron straightening was performed at a low temperature of 80 to 170 ° C. The combing after completion was very good, and a rinsing effect was observed.

Comparative Example 10 A barber A (male 40 years old) and a barber B (female 35 years old) were given a model of 10 persons each, and were contracted by a straightening iron method using a commercially available waving lotion solution for straightening hair. Hair straightening was performed by the following method and evaluated. [Treatment method (conditions)] Same as in Example 10. [Evaluation Results] Hair was sometimes cut. The hair was wet and began to evaporate during the ironing procedure.
Even if the hair is straightened with an iron while drying, the hair of the oxidizing agent returns the curly hair. Damage and dustiness are seen in the finish of the hair. The model did not have the desired straight state, volume and hair style.

The following effects have been observed with the waving lotion of the present invention. (1) The quality of the waving lotion solution can be maintained over a long period of time. (2) The effective use rate of the first liquid has improved. (3) The time required for the operation can be shortened, the productivity can be improved, and the engineers can be effectively used. (4) The treatment temperature was lowered, and the hair was not damaged by heat. (5) Rinse effect was obtained and combing became smooth.

Further, the waving lotion of the present invention comprises
Satisfying various properties required for each application of cold wave, iron perm and hair straightening, the treatment method using the waving lotion of the present invention is much better than the conventional treatment method, The effects of each application are briefly summarized as follows. In the case of cold wave, the practitioner can correctly calculate the treatment method in advance according to the target hair curl, and is hardly affected even when the hair quality and environment are different, and the result of cold perm according to the practitioner's intention Is obtained. Further, by using the waving lotion according to the present invention, cold wave treatment by iron winding method can be performed for the first time.

In the case of an iron perm Since the iron can be treated at a low temperature of 80 to 170 ° C., curls can be formed while keeping the moisture of the hair. Therefore, since the curl is kept at a low temperature and keeping the moisture, the curl is hardly reduced by the moisture of the second liquid. In other words, the practitioner only has to apply the curl according to the intended hairstyle. Further, since the operation is simplified in this way, even an unskilled person can obtain the same result as an expert. In addition, although the ironing operation time required 25 to 50 minutes in the conventional case, the treatment method of the present invention can greatly reduce the time to 8 to 25 minutes, which leads to improvement in productivity and improvement in service to customers. In the case of hair straightening It is possible to simplify long and complicated process times and perform operations faithful to the principle of cold perm, making it possible to achieve the purpose of hair straightening in a simple and short time.
