DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a second agent of a hair deforming agent such as a permanent wave agent and a hair straightening agent.

[0002]

2. Description of the Related Art In general, a hair deforming agent such as a permanent waving agent or a hair straightening agent reduces and opens the S--S bond in the hair using a reducing substance, and then oxidizes the hair. The hair is deformed by oxidative closure using a substance or by standing naturally (oxygen in the air). Usually, the composition (first agent) for reducing and opening the S—S bond in the hair contains an alkaline agent in addition to the reducing substance, and the pH of the composition is alkaline. Further, -S produced in the hair by the first agent treatment
Oxidizing substances to be added to the composition for oxidatively closing the H group (second agent) are mainly made of bromate in Japan, and are used to ensure the stability of the main agent. The pH of the product is kept neutral to weakly alkaline.

[0003] In the treatment, it is instructed to perform an intermediate washing before applying the second agent for the purpose of sufficiently exhibiting the oxidizing ability. Especially for permanent wave preparations, the subject will be washed with intermediate water in a shampoo bowl with the hair wound on the rod, and the rod sandwiched between the head and the shampoo bowl will be painful as it presses the scalp There is. If the practitioner has a large number of customers, the intermediate washing may be omitted in order to shorten the time. On the other hand, acid rinsing is sometimes used instead of intermediate washing, but acid rinsing has a high acidity, and when applied to hair, the hair shrinks due to a sudden pH change, and the hair surface is wrinkled, so-called wrinkle care Could be For the reasons described above, there are many cases in which intermediate water washing or intermediate acid rinsing has not been performed before the application of the second agent.

As described above, when the intermediate washing and the intermediate acid rinsing are not performed, the following problems may occur. In other words, since the pH of the composition is in a neutral to weakly alkaline range, the second agent alone is used for the hair of the permanent wave agent of the mainstream bromate and the second agent of the hair straightening agent in Japan. It is insufficient to neutralize the remaining alkali, and the hair damage and deterioration of the hair feel after the treatment caused by the remaining alkali are inevitable.

Therefore, there is a need for a method for sufficiently neutralizing and reducing the residual alkali in the hair with only the second agent without the troubles of intermediate washing and intermediate acid rinsing in the treatment of permanent waving and hair straightening. I was

[0006]

In this situation, the present inventors have conducted intensive studies, and as a result, by adding a specific anionic polymer to the second agent, the alkali remaining in the hair is gently and sufficiently neutralized. It was found that the feeling after the treatment was improved and the stability of the second agent bromate was improved surprisingly, and the present invention was completed.

[0007] That is, the present invention provides a second agent for permanent wave, which comprises a specific anionic polymer and a cationic polymer. Hereinafter, the present invention will be described in detail.

The component (A) oxidizing substance used in the present invention is not particularly limited, and known oxidizing substances can be widely used. Specifically, hydrogen peroxide, urea peroxide, sodium percarbonate, potassium percarbonate, ammonium percarbonate, sodium perborate, ammonium persulfate, sodium persulfate, potassium persulfate, sodium bromate, potassium bromate, etc. No. These oxidizing agents may be used alone or in combination of two or more. Of these, bromates such as sodium bromate and potassium bromate and hydrogen peroxide are preferred from the viewpoint of versatility in Japan.

In the present invention, the anionic high molecular polymer of the component (B) comprises (a) a half ester of itaconic acid and a polyoxyethylene alkyl ether or an ester of methacrylic acid and a polyoxyethylene alkyl ether; ) At least one selected from copolymers composed of at least one monomer selected from acrylic acid, methacrylic acid and their alkyl esters can be used. These materials are from Acrylates / St

mer, Acrylates / Ceteth-20 I
taconateCopolymer, Acrylat
es / Steareth-20 Methacryla
te Copolymer or Acrylates
/ Ceteth-20 Methacrylate Co
It is known by the name polymer.

Since the anionic high molecular polymer used in the present invention is an acidic substance, it plays a role of consuming and neutralizing alkali remaining in hair. This object can be achieved by using an acrylic acid-based or methacrylic acid-based anionic high molecular polymer conventionally used. For example, acrylic acid-based anionic high-molecular polymer represented by carboxyvinyl polymer, etc., is thickened by neutralization with an alkali agent,
It is often used as a gelling agent, but has the property of being suspended and thickened even in an unneutralized (acidic) state when it is put into water, and exhibits a gel state. Therefore, if it is the second agent for hair straightening agent, it is still unsuitable to mix it with a composition such as the second agent for permanent wave, which uniformly penetrates the hair wound on the rod. However, according to the composition of the present invention,
Since it is in a liquid state without gelling in the vicinity of acidic to neutral, it can be sufficiently used as a second agent for permanent wave.

When the bromate is used as an oxidizing agent, the pH of the composition of the present invention is adjusted to 4.5 to 7.0. Since bromate is usually stable in a neutral region, the second agent for permanent wave, which is a main agent of bromate, is conventionally p
H is adjusted to about 5.0 to 7.5, and the pH is substantially adjusted to 6.0 to 7.5 because the lower the concentration is toward the acidic side, the lower the stability is.
Most are adjusted to 7.5. In the case of the present invention,
If the pH of the composition is adjusted to a neutral range, the ability to theoretically neutralize the alkali remaining in the hair cannot be expected, and it is desirable that the composition be as acidic as possible. However, according to the anionic high molecular polymer used in the present invention, the bromate is changed to pH.
It has been found that in the range of 4.5 to 6.0, it is possible to stably hold the hair, and it is also possible to exert the neutralizing ability of the alkali remaining in the hair.

The compounding amount of the anionic high molecular polymer of the present invention is preferably 0.01 to 10% by weight. 0.01
When the amount is less than 10% by weight, sufficient residual alkali neutralizing action is not exhibited. More preferably, it is 0.1 to 5.0% by weight.

When the component (C) cationic polymer is further added to the composition of the present invention, the feel of the treated hair is improved. Examples of the cationic polymer include, for example, a water-soluble polymer containing an amino group or an ammonium group bonded to a polymer chain, or containing at least dimethyldiallylammonium halide as a constituent unit, and a cationized cellulose derivative or a cationized cellulose derivative. Guar gum derivatives,
And diallyl quaternary ammonium salt / acrylamide copolymers and quaternized polyvinylpyrrolidone derivatives.

Commercially available cationized cellulose derivatives include Leogard G from Lion Corporation and Polymers JR-125, JR-400 and JR-400 from Union Carbide.

00 and the like. Commercially available cationized guar gum derivatives include Jaguar C-13S, -14S, -17, 210, and RHONE-POULENC.
-162, HI-CARE1000 and the like.
As the cationic diallyl quaternary ammonium salt / acrylamide copolymer, commercially available products include Mercoat 100, 550 and the like. Commercially available quaternized polyvinylpyrrolidone derivatives include Guffcoat 732, 75 manufactured by ASP Japan Co., Ltd.
5,755N and the like.

Among these, a cationized cellulose derivative and a diallyl quaternary ammonium salt / acrylamide copolymer are preferred.

The cationic high polymer is considered to form an ionically complex with the anionic high polymer of the present invention. In order to ensure the residual alkali neutralization ability of the anionic high polymer, An appropriate amount of the cationic polymer is 5 to 95% by weight of the anionic polymer.

In addition, if necessary, higher alcohols, polyhydric alcohols, oils such as silicone and triglyceride, surfactants, polymer substances, pH adjusters, sequestering agents, amino acids, protein hydrolysates, fragrances, preservatives Agents, anti-inflammatory agents, coloring agents, sunscreen agents, vitamins, propellants and the like.

The dosage form of the second composition for permanent waving of the present invention is preferably liquid or foamy. When used as a second hair straightening agent, the composition is liquid, foamy, creamy or gel-like. It can also be in the form.

Further, in order to obtain the effects of the present invention, it is necessary to perform a treatment by combining the first agent for permanent wave containing a reducing substance and an alkali agent with the composition of the present invention. Furthermore, by combining with the first agent composition containing a cationic high molecular polymer, the feeling during plain rinse and finish can be further improved.

The reducing substance referred to here is a main agent for reducing and cutting the disulfide bond of cystine in keratin, which is a constituent protein of the hair, so that the hair is waved. Examples of the reducing substance include thioglycolic acid, ammonium thioglycolate, thioglycolate such as monoethanolamine thioglycolate, esters of thioglycolic acid such as glycerin thioglycolate, cysteine, cysteine hydrochloride, and acetyl. Cysteine salts such as cysteine,

Sulfites such as sodium sulfite, sodium hydrogen sulfite, potassium sulfite, and ammonium sulfite are used.

These reducing substances may be used alone or in combination of two or more.
And, the first for permanent wave of this reducing substance
The content in the composition is 1 to 10% by weight, particularly 2 to 8% by weight.
% Weight is preferred. That is, if the content in the first agent for permanent wave is less than the above range, it is not possible to apply sufficient waving to the hair, and if the content is more than the above range, disulfide bonds in the hair are excessively reduced, Elution of the protein from the hair becomes severe, and the hair may be greatly damaged.

As the alkaline agent, ammonia or monoethanolamine, triethanolamine,
Alkanolamines such as isopropanolamine and aminomethylpropanol, hydroxides of alkali metals such as sodium hydroxide and potassium hydroxide, ammonium carbonate and sodium carbonate, carbonates such as sodium hydrogencarbonate and basic amino acids such as arginine, Those generally used in cosmetics can be mentioned. These alkali agents may be used alone or in combination of two or more. The content of the alkali agent in the first agent for permanent wave is preferably 0.05 to 15% by weight, particularly preferably 0.1 to 10% by weight. That is, when the content in the first agent for permanent wave is less than the above range, the hair cannot be sufficiently swollen and a uniform wave cannot be formed. If the amount is more than the above range, the hair may be over-swelled, the protein may be eluted from the hair intensely, or the scalp may be stimulated. It is desirable to use a combination of the above reducing substances and alkali agents.

Further, as the cationic high molecular polymer,
For example, the same component (C) as described above is suitable. The desired effect can be obtained by using the combination of the first component of the permanent wave containing the above components and the second component of the present invention.

The feeling of plain rinse and finish,
The finished wave, the amount of residual alkali in hair and the residual ratio of bromate were evaluated according to the following criteria. <Evaluation criteria> 1. Feeling of plain rinse and finish ◎: very good ○: good △: slightly poor ×: poor Finished wave ○: Uniform wave △: Slight wave unevenness ×: Wave unevenness Hair residual alkali content 0.2 g of hair was collected from each panel, immersed in 100 ml of distilled water, and gently stirred. The pH after 5 minutes was measured and used as a measure of the amount of residual alkali. 4. Example 1 and Comparative Examples 1 to 3 were stored in a thermostat at 50 ° C. for one month, and the rate of residual bromate was measured. ◎: 100 to 98% ：: 98 to 95% Δ: 95 to 85% ×: Less than 85% These results are shown in Table 1.

As can be seen from the results, the evaluations of Examples 1 and 2 were all good. Comparative Example 2 is an example in which a carboxyvinyl polymer was used as the anionic polymer, but this second agent was in a gel state and did not penetrate into the rod even when applied to hair wound on the rod, It could not be applied uniformly. As a result, a uniform wave could not be obtained, and further, neutralization of the alkali remaining in the hair could not be uniformly performed, so that good results could not be obtained. Further, the bromate could not be stabilized.
