Description

  The present invention relates to a hair dye composition, and more particularly to a hair dye composition containing a direct dye and an aromatic alcohol and dyeing by repeated use a plurality of times.

Conventionally, temporary hair dyes that use a pigment, carbon black or the like to temporarily dye hair are known. Such a temporary hair dye has a convenience that it can be easily washed away with a shampoo or the like, compared with a permanent hair dye dyed with an oxidative dye, but has a problem of poor color retention. Therefore, a hair dye composition containing a direct dye, an aromatic alcohol and the like as a dye described in Patent Document 1 is known. Such a hair dye composition does not require shampooing immediately after use, and the hair is gradually dyed to a desired color through repeated use. In addition, it has a long color compared with the temporary hair dye, and is more convenient than a permanent hair dye that requires a mixing treatment of a plurality of agents. A hair dye composition in which such a direct dye is blended is blended with a silicon-based resin or the like in order to prevent secondary adhesion.
JP 2001-172141 A

  However, the hair dye composition using such a direct dye has a problem that secondary adhesion is not sufficiently prevented. Moreover, the problem that a feeling of stickiness arises with the resin mix | blended in order to prevent secondary adhesion also arose. On the other hand, when the amount of the direct dye is made small in order to suppress the secondary adhesion, there is a problem that the number of repetitions until the hair is dyed increases and the use becomes complicated.

  The present invention has been made paying attention to the problems existing in the prior art as described above. The purpose of the present invention is to provide a hair dye composition that is excellent in hair dyeing power and can prevent secondary adhesion and stiff feeling in a hair dye composition that is dyed by repeated use using a direct dye. is there.

  (C) Betaine-modified silicone is blended in order to improve dyeability, prevent secondary adhesion due to a direct dye, and stiff feeling. Specific examples include dimethicone propyl PG betaine. (C) Content of betaine modified silicone is 0.001-5 mass%, Preferably it is 0.01-2.5 mass%, More preferably, it is 0.05-1.0 mass%. (C) The effect which prevents secondary adhesion falls that content of betaine modified silicone is less than 0.001 mass%. On the other hand, even if it exceeds 5% by mass, it is difficult to obtain a further secondary adhesion preventing effect.

  (D) The alkyl acrylate copolymer is blended in order to improve dyeability and prevent secondary adhesion by a direct dye. (D) The alkyl acrylate copolymer is a polymer composed of a homopolymer or copolymer of an alkyl ester of acrylic acid and / or methacrylic acid. Further, an alkyl styrene acrylate copolymer obtained by copolymerizing styrene or vinyl acetate with these polymer polymers, an alkyl acrylate vinyl acetate copolymer, or the like may be used.

  Specifically, polyethyl acrylate, polybutyl acrylate, alkyl acrylate / alkyl methacrylate / polyoxyethylene (20) stearyl ether copolymer, alkyl acrylate / itaconic acid polyoxyethylene alkyl monoester copolymer Etc. These (D) acrylic acid copolymers may be blended singly or in combination of two or more.

  The blending amount of these (D) alkyl acrylate copolymers is 0.005 to 15% by mass, preferably 0.01 to 10% by mass, more preferably 0.05 to 5% by mass. (D) If the amount of the alkyl acrylate copolymer is less than 0.005% by mass, the effect of preventing secondary adhesion is lowered. On the other hand, even if it exceeds 15% by mass, it is difficult to obtain the effect of preventing further secondary adhesion, and it is easy to cause the stiffness.

  (E) Polyvinylcaprolactam is blended to improve dyeability, prevent secondary adhesion with a direct dye, and prevent stickiness. (E) The compounding quantity of polyvinyl caprolactam is 0.01-10 mass%, Preferably it is 0.05-5 mass%, More preferably, it is 0.1-3 mass%. (E) When the compounding quantity of polyvinyl caprolactam is less than 0.01 mass%, the effect which prevents secondary adhesion will fall. On the other hand, even if it exceeds 10% by mass, it is difficult to obtain a further secondary adhesion preventing effect.
