Description

  The present invention relates to a hair deformation treatment composition, and more particularly, the present invention relates to a hair deformation treatment composition having high wave forming efficiency and good hair feel after the deformation treatment.

  Hair deformation treatments such as applying waves to hair or correcting curly hair are performed using a hair deformation treatment agent such as a permanent wave agent or a hair straightener containing a reducing agent. Since the hair deformation treatment includes a process of cleaving the disulfide bond of cystine in the hair keratin with a reducing agent, damage to the hair and accompanying deterioration of the hair feel (hand touch) after treatment are inevitable. In order to improve this problem, for example, it has been proposed to use a copolymer of cystine and silicone.

Fragrance Journal, “Fragrance Journal”, April 15, 2001, Vol. 29, No. 4, p. 117-118.

Japanese Patent Application Laid-Open No. 2004-149478. In Non-Patent Document 1 described above, a hair conditioning copolymer, which is a copolymer of cystine and silicone, is introduced. By penetrating the copolymer into the hair, the hair is replenished with disulfide bonds. It is going to improve sustainability. Furthermore, the polymer is polymerized on the surface of the hair to form a film, thereby improving the durability of the wave and improving the feel of the hair. The hair deformation treatment agent disclosed in the above-mentioned Patent Document 1 is a combination of a reducing agent and a polymer that is a copolymer of cystine and silicone similar to the case of the above-mentioned Non-Patent Document 1. In addition to forming a wave, a polymer film is formed on the hair surface to improve the feel of the hair and the sustainability of the wave. Further, this hair deformation treatment agent can further improve the sustainability of the wave by dehydrating the hair in combination with a protein astringent.

  By the way, in hair deformation treatment, there is a case where the amount of reducing agent or oxidizing agent in the hair deformation treatment agent is increased in order to improve the wave forming efficiency, which is an index of strength of deformation (wave). , May cause stronger hair damage and worse feeling.

  According to the research of the present inventor, the hair conditioning copolymer of Non-Patent Document 1 and the hair deformation treatment agent of Patent Document 1 are effective in improving the sustainability and feeling of the wave. It is not effective for strong hair damage and deterioration of touch as a price for improving formation efficiency. That is, in hair deformation treatment, it has not always been easy to achieve both high wave forming efficiency and good hair feel after treatment.

  Then, this invention makes it the technical subject which should be solved to provide the hair deformation processing agent which can obtain high wave formation efficiency, without impairing the touch of hair.

  In the process of pursuing the means for solving the above problems, the inventor of the present application uses a specific cationic polymer and a metal salt of paraphenol sulfonic acid in combination with the second agent of the hair deformation treatment agent, so that the hair feel after the treatment. The present invention was completed by finding that a hair deformation treatment capable of obtaining a high wave forming efficiency is possible without impairing the hair.

(Configuration of the first invention)
The configuration of the first invention of the present application for solving the above problems comprises a first agent containing a reducing agent and a second agent containing an oxidizing agent, and the second agent is further 0.1 to 2.0% by mass. It is a hair deformation treatment composition containing the following (A) component and the following (B) component of 0.03-0.65 mass%.

  (A) Metal salt of paraphenolsulfonic acid.

  (B) Dimethyldiallylammonium chloride / acrylic acid copolymer.

  In said 1st invention, content of (A) component and (B) component is represented with the mass% number in a 2nd agent.

(Configuration of the second invention)
The structure of the 2nd invention of this application for solving the said subject is the hair deformation treating agent composition which concerns on the said 1st invention, (A) component is zinc paraphenol sulfonate.

(Configuration of the third invention)
The composition of the third invention of the present application for solving the above-mentioned problem is the hair deformation treatment composition according to the first invention or the second invention, wherein the mass of the content of the component (A) with respect to the content of the component (B) The ratio (A) / (B) is in the range of 0.25-22.

  In this third invention, the mass ratio (A) / (B) is a mass ratio of the component (A) and the component (B) blended in the second agent of the hair deformation treating agent composition, ) Component and (B) component are not related even if they are blended in the first agent.

  According to the first invention, since the second agent of the hair deformation treatment composition contains the component (A) and the component (B), in the hair deformation treatment, high wave formation without impairing the feel of the hair after the treatment. Efficiency is obtained. And even if it increases the compounding quantity of the reducing agent or oxidizing agent in a hair deformation treatment agent to a certain extent rather than usual, this effect is acquired. In order to acquire this effect, it is necessary for a 2nd agent to contain 0.1-2.0 mass% (A) component and 0.03-0.65 mass% (B) component.

  Since the metal salt of paraphenolsulfonic acid as component (A) has a strong protein astringent action, it permeates into the hair and dehydrates the hair, thereby converging the hair. As a result, the hair is tightened to improve the wave forming efficiency.

  The component (B), dimethyldiallylammonium chloride / acrylic acid copolymer, is a copolymer in which acrylic acid monomers constituting an anionic portion are mixed with dimethyldiallylammonium chloride monomers constituting a cationic portion. It is a coalescence. For this reason, it has been found that the anionic portion has a function of improving the feel of hair based on the cationic portion and at the same time canceling the decrease in wave forming efficiency, which is a disadvantage of the hair. In order to exhibit this effect satisfactorily, the molar ratio of the cationic monomer to the anionic monomer constituting the copolymer is within the range of about 6.5: 3.5 to 9.5: 0.5. Preferably there is.

  In addition, even if it is a polymer of the category close | similar to (B) component, said effect will not be acquired if it does not have the balance of the structural ratio of the above cationic monomers and anionic monomers. In the case where the cationic monomer is in excess of the above balance range, for example, “Marcote 100” manufactured by Nalco Japan, which is polydimethylmethylenepiperidinium chloride, becomes a substantially total cationic polymer, The above effect is not ensured. On the contrary, the anionic monomer is excessive in excess of the above-mentioned balance range, for example, “Marquat Plus 3330” manufactured by Nalco Japan, which is an acrylamide / acrylic acid / dimethyldiallylammonium chloride copolymer, This effect is not ensured because it is an amphoteric polymer, not a cationic one.

  If the content of the component (A) in the second agent is less than 0.1% by mass, sufficient effect of improving the wave forming efficiency cannot be obtained, and if the content exceeds 2.0% by mass, the hair after the treatment The feeling will be worse. On the other hand, if the content of the component (B) in the second agent is less than 0.03% by mass, the effect of improving hair feel after treatment cannot be obtained, and if the content exceeds 0.65% by mass, it is sufficient. The effect of improving the wave forming efficiency cannot be obtained. That is, when the contents of the component (A) and the component (B) in the second agent are within the above ranges, a sufficient wave forming efficiency improvement effect and a hair feel improvement effect after the treatment are well balanced. compatible.

  According to the second invention, since the component (A) is zinc paraphenol sulfonate, the wave forming efficiency of the hair deformation treatment composition is further improved.

  According to the third invention, since the mass ratio (A) / (B) of the content of the component (A) to the content of the component (B) in the second agent is within the range of 0.25 to 22, The effect that high wave formation efficiency can be obtained without impairing the feel of the later hair is further improved. If this mass ratio (A) / (B) is less than 0.25, it may be difficult to obtain sufficient wave forming efficiency. On the other hand, if the mass ratio (A) / (B) exceeds 22, it may be difficult to obtain satisfactory results for the feel of the hair after the description.

  Next, modes for carrying out the present invention will be described including the best mode.
