Description

  The present invention relates to a hair cosmetic composition used as, for example, a hair dye or a hair bleaching / decoloring agent. More specifically, the present invention relates to a hair cosmetic composition capable of improving viscosity stability with rapid onset of thickening. About.

  In general, as hair cosmetic compositions, for example, hair dyes and hair bleaching / destaining agents containing an alkaline agent and an oxidizing agent are known. The oxidizing agent decolorizes melanin in the hair. The alkaline agent improves the lightness of the hair after decolorization by promoting the action of the oxidizing agent. Further, when the alkaline agent contains a dye in the hair cosmetic composition, it improves the dyeability by swelling the hair and improving the permeability of the dye into the hair. For example, a thickener may be added to the hair dye and the hair bleaching / decoloring agent in order to prevent dripping by imparting a predetermined viscosity at the time of use and to improve the adhesion to the hair. Incidentally, a hair cosmetic composition composed of a powdery alkaline agent is also known. Such a powder hair cosmetic composition is mixed with water at the time of use, and then applied to hair and used for decolorization or hair dyeing treatment. The powdered hair cosmetic composition is characterized in that it is simpler to use than a creamy or liquid composition, and is excellent in handleability and portability.

  Conventionally, for example, hair dyes or hair bleaching / destaining agents disclosed in Patent Documents 1 and 2 are known. Patent Document 1 discloses a first agent of a powdery hair bleaching agent containing hydroxyethyl cellulose and tragacanth gum as a thickener, and a second agent containing hydrogen peroxide and the like. Patent Document 1 imparts viscosity to a mixture by mixing the first agent and the second agent at the time of use. Patent Document 2 discloses a powdery hair dye composition containing hydroxyethyl cellulose, guar gum and the like as thickeners. Patent Document 2 gives viscosity to the composition by mixing the powdered hair dye composition and water at the time of use.

First, the lid body 22 is removed from the container body 21, the package of the first agent 11 and the second agent 12 is taken out, and the packages are opened, and each agent is put into the container body 21 as shown in FIG. The mixture is brought into contact with each other to form a mixture 13. Subsequently, as shown in FIG. 1C, the lid body 22 is attached to the container main body 21, and the occluding container 20 is shaken up and down. At this time, in the closable container 20, each agent is mixed, and air is mixed into the mixture 13 by shaking the mixture 13 of each agent up and down. Thus, the foaming of the mixture 13 is started by the operation of shaking the air into the mixture 13. Then, the foaming operation is completed by shaking the closable container 20 a predetermined number of times. By this foaming operation, a foamy hair decoloring / destaining agent 14 is prepared. Next, as shown in FIG. 1D, the lid body 22 is removed, and the foamy hair decoloring / destaining agent 14 in the container body 21 is directly taken out by hand, for example, and applied to the hair. At this time, since the hair decoloring / destaining agent is foamy, it can be easily adapted to the hair without causing dripping. And hair is decolored or decolored by leaving the hair to which the hair decoloring / decoloring agent is applied for a predetermined time. Subsequently, the hair decoloring / destaining agent is washed away with water or warm water to complete the decoloring or destaining process.

(Second Embodiment)
Hereinafter, a second embodiment in which the hair cosmetic composition according to the present invention is embodied as a hair dye will be described. The hair dye according to this embodiment is a two-component hair cosmetic composition composed of a first agent and a second agent.

The first agent contains, for example, (A) an anionic surfactant, (C) a thickener, (D) starch, an alkaline agent, and an oxidation dye.
Oxidative dyes are compounds that can develop color due to oxidative polymerization by an oxidant contained in the second agent, and are classified as dye intermediates and couplers. The oxidation dye contains at least a dye intermediate.

  Examples of the dye intermediate include p-phenylenediamine, toluene-2,5-diamine (paratolylenediamine), N-phenyl-p-phenylenediamine, 4,4′-diaminodiphenylamine, p-aminophenol, o- Aminophenol, p-methylaminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2-hydroxyethyl-p-phenylenediamine, o-chloro-p-phenylenediamine, 4-amino-m -Cresol, 2-amino-4-hydroxyethylaminoanisole, 2,4-diaminophenol, and salts thereof. Among these specific examples, only 1 type may be contained independently and 2 or more types may be combined and contained.

  Couplers develop color by binding to dye intermediates. Examples of the coupler include resorcin, 5-amino-o-cresol, m-aminophenol, α-naphthol, 5- (2-hydroxyethylamino) -2-methylphenol, m-phenylenediamine, and 2,4-diaminophenoxyethanol. , Toluene-3,4-diamine, 2,6-diaminopyridine, diphenylamine, N, N-diethyl-m-aminophenol, phenylmethylpyrazolone, and salts thereof. Among these specific examples, only 1 type may be contained independently and 2 or more types may be combined and contained. Since the oxidative dye can change the color tone of the hair in various ways, it is preferable that at least one selected from the specific examples of the dye intermediate and at least one selected from the specific examples of the coupler. Composed. The first agent is suitably selected from dyes other than the above-mentioned oxidation dyes, for example, at least one selected from oxidation dyes and direct dyes listed in "Quasi-drug raw material standards" (issued in June 2006, Yakuji Nippo). You may contain.

The second agent in the hair dye is used for dyeing hair after being mixed with the first agent. The specific configuration of the second agent is the same as that of the second agent according to the first embodiment.
The dosage form of the first agent is configured in a solid form in order to preserve (D) starch in a solid form. Examples of the solid form include a powder form and a particulate form. The dosage form of the second agent is not particularly limited, and specific examples include solid (except when the oxidizing agent is liquid at normal temperature), liquid, gel, foam, and cream. Examples of the solid form include a powder form and a particulate form. In addition, when a 2nd agent is a solid state, it is necessary to add the solvent mentioned above at the time of use. Examples of the liquid include an emulsion. At the time of using the hair dye, a mixture is prepared by mixing the first agent and the second agent. The dosage form of the mixture is not particularly limited, and may be any of liquid, gel, foam, and cream. The required amount of the mixture is then applied to the hair, attached to a thin gloved hand, comb or brush.

The hair dye according to the present embodiment has the following advantages in addition to the effects of the first embodiment.
(5) The hair dye according to this embodiment includes, for example, (A) an anionic surfactant, (C) a thickener, and (D) a solid first agent containing starch, and (B), for example. It comprised from the 2nd agent containing a cationic surfactant. Thereby, (A) anionic surfactant and (B) cationic surfactant can be made to contact in presence of a solvent at the time of use. Therefore, when a 1st agent and a 2nd agent are mixed and a mixture is obtained, the thickening effect can be provided to a mixture in a short time. This is presumably because (A) the anionic surfactant and (B) the cationic surfactant are brought into contact and interact in an ionic state when dissolved in the solvent.

  (6) The hair dye which concerns on this embodiment contains solid (D) starch in a 1st agent. Accordingly, it is possible to increase the speed of the thickening effect and improve the viscosity stability with respect to the mixture obtained by mixing the first agent and the second agent at the time of use.

The embodiment may be modified as follows.
-About the hair dye of 2nd Embodiment, you may apply as a 1 agent type or 3 agent type hair dye similarly to the hair decoloring and decoloring agent of 1st Embodiment. Moreover, about the hair dye of 2nd Embodiment, you may comprise more than 3 agent type.
