Description

  The present invention relates to a hair treatment agent. More specifically, the present invention relates to a hair treatment agent that can sufficiently prevent discoloration and discoloration of hair after hair dyeing when hair is dyed using a hair dye composition containing an oxidizing agent.

  In the present invention, the “fading” of hair after dyeing is mainly caused by the outflow (color loss) of the dye from the hair during hair washing and the like, and the decomposition of the dye itself (fading) due to the influence of sunlight or the like. This means the change or deterioration of the color of the hair after dyeing.

  Hair dyes containing an oxidizing agent and a dye are widely used. In order to maintain a good color tone of the hair after the hair dyeing treatment with such a hair dye, it is effective to take measures to prevent discoloration of the hair due to subsequent shampooing, etc., or to prevent the dye from fading due to sunlight. . Conventional proposals for preventing hair fading include, for example, Patent Document 1 and Patent Document 2 below.

Japanese Patent Application Laid-Open No. 4-338317 discloses a hair cosmetic containing an amino-modified silicone derivative and an ultraviolet absorber. This hair cosmetic prevents damage to the hair due to ultraviolet rays, and gives the hair gloss, smoothness and smoothness. It is said to give good passability.

Japanese Patent Application Laid-Open No. 2004-262609 discloses a cosmetic for preventing hair fading, which contains an ultraviolet absorber and a specific phenol derivative, and this cosmetic for preventing fading of hair is fading, especially by sunlight. The effect of preventing fading is high.

  However, according to the study of the present inventor, in hair that has been severely damaged by repeated oxidative hair dyeing treatment or other chemical treatment, fading occurs due to fading due to the outflow (color loss) of the dye from the hair, The hair cosmetics described in Patent Document 1 and Patent Document 2 do not exhibit an effective anti-fading effect. Furthermore, even when these hair cosmetics were used for severely damaged hair, the hair feel was not sufficient.

  Therefore, the present invention provides a hair treatment agent that exhibits a sufficient anti-fading effect even on hair that has been severely damaged by repeated chemical treatments, and that can give a good feel to the hair. It is a problem to be solved.

  In the process of pursuing the means for solving the above problems, the present inventor selectively blended a hair treatment agent with a specific type of silicone having a specific degree of polymerization together with an ultraviolet absorber, and further added acidic amino acids. The present invention was completed by obtaining the knowledge that the problem can be solved when blended.

(Configuration of the first invention)
The structure of this invention 1 for solving the said subject is a hair treatment agent containing the following (A) component-(C) component.

(A) One or more highly polymerized silicones selected from the following components (A1) to (A3) both having an average degree of polymerization in the range of 2,000 to 20,000.
(A1) Highly polymerized dimethylpolysiloxane.
(A2) Highly polymerized dimethiconol.
(A3) Highly polymerized amino-modified silicone.

  (B) One or more ultraviolet absorbers.

  (C) One or more acidic amino acids.

  In the first invention, the “degree of polymerization” in the case of the average degree of polymerization of amino-modified silicone means the total degree of polymerization of the dimethylsiloxane part and amino-modified siloxane part, which are monomer units of amino-modified silicone.

(Effect of the first invention)
Since the hair treatment agent of the first invention contains the above-mentioned components (A) to (C), the hair treatment agent is not damaged so much. It is possible to exert a sufficient fading prevention effect on the hair and give a good feel to the hair.

  The reason why such an effect is obtained by the hair treatment agent of the first invention is not necessarily fully clarified, but at least the following points can be pointed out.

  That is, one or more highly polymerized silicones selected from the components (A1) to (A3) having an average degree of polymerization in the range of 2,000 to 20,000 are blended as the component (A), and (C) Since acidic amino acids are blended together as a component, dye outflow (color loss) from hair is sufficiently prevented even in hair that has been severely damaged. In addition, when the average degree of polymerization of the highly polymerized silicone is out of the range of 2,000 to 20,000, the effect of preventing color fading is insufficient even when the component (C) is blended together. The above point and the anti-fading effect of the dye by the ultraviolet absorbent as the component (B) are combined, and it is considered that fading of hair is effectively prevented even in severely damaged hair.

  Further, the component (A) mainly gives a good feel to the hair such as the gloss of the hair after finishing and the goodness of fingers. Regarding this effect, if the average degree of polymerization of the highly polymerized silicone is less than 2,000, the feel-improving effect becomes insufficient, and if the average degree of polymerization of the highly polymerized silicone exceeds 20,000, the component (A) and / or (B ) The viscosity of the component is too high and is not practical from the viewpoint of solubility in the hair treatment agent base and difficulty in handling during production.

(Configuration of the second invention)
The structure of the second invention of the present application for solving the above problem is that the component (A) in the hair treatment agent according to the first invention is one or more selected from the components (A1) and (A2), and (A3 ) A hair treatment agent comprising at least one selected from the components.

(Effect of the second invention)
As 1 or more types of (A) component mix | blended with a hair treatment agent, the combination of 1 or more types chosen from (A1) component and (A2) component, and 1 or more types chosen from (A3) component, Particularly preferred.

(Configuration of the third invention)
The constitution of the third invention of the present application for solving the above problem is that the component (B) in the hair treatment agent according to the first invention or the second invention is a benzoic acid ultraviolet absorber, a salicylic acid ultraviolet absorber, cinnamon It is a hair treatment agent that is at least one selected from an acid ultraviolet absorber and a benzophenone ultraviolet absorber.

(Effect of the third invention)
Although the kind of ultraviolet absorber mix | blended as (B) component is not limited, Especially it is chosen from a benzoic acid type ultraviolet absorber, a salicylic acid type ultraviolet absorber, a cinnamic acid type ultraviolet absorber, and a benzophenone type ultraviolet absorber. It is preferable that it is a seed or more.

(Configuration of the fourth invention)
The constitution of the fourth invention of the present application for solving the above problems is that the component (C) in the hair treatment agent according to any of the first to third inventions is selected from taurine, glutamic acid, aspartic acid, glutamine, and asparagine. It is a hair treatment agent which is 1 or more types.

(Effect of the fourth invention)
(C) Although the kind of acidic amino acids mix | blended as a component is not limited, One or more types chosen from taurine, glutamic acid, aspartic acid, glutamine, asparagine can be illustrated preferably.

  The hair treatment agent of the present invention is not only for hair that is not damaged so much, but also exhibits sufficient fading prevention effect for hair that has been severely damaged by repeated chemical treatment, Moreover, a good feel can be given to the hair.

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

  The content of the component (C) in the hair treatment agent is not limited, but in the hair treatment agent mixed at the time of use, it is preferably 0.001 to 0.001 in the hair treatment agent on the premise that it is the content at the time of mixing. 5 mass%, particularly preferably 0.005 to 3 mass%. When the content of the component (C) is less than 0.001% by mass, there is a concern that the blending effect does not sufficiently appear, and when it exceeds 5% by mass, there is a concern that the hair tends to be sticky.
