Description

  The present invention relates to a hair cosmetic composition. More specifically, the present invention relates to a hair cosmetic composition that exerts an excellent hair dyeing effect and has less irritating odor and less irritation to the skin.

  A hair dye is composed of a first agent containing an oxidative dye and an alkaline agent and a second agent containing an oxidizer, and is prepared by mixing the first agent and the second agent at the time of use and applying to the hair. To be dyed.

  Conventionally, as a hair dye, a two-component type comprising a first agent containing an oxidizing dye such as paraphenylenediamine, an alkaline agent such as ammonia or monoethanolamine, and a second agent containing an oxidizing agent such as hydrogen peroxide. Oxidative hair dyes are widely used. In this hair dye, an oxidative dye penetrates into hair and oxidative polymerization is carried out in the hair to produce a dye, thereby dyeing the hair. Ammonia, which is widely used, is a component having a high hair dyeing effect, but has a very unpleasant pungent odor. Monoethanolamine, which is an alkaline agent with no irritating odor, is also widely used. However, when the hair coloring effect is obtained by increasing the content, the skin may be irritated when used. Therefore, in the prescription design of the other part, it has been a subject to produce a high hair dyeing effect.

  As a method for solving this problem, the hair treatment agent composition (Patent Document 1) using an alkaline agent and a reducing agent with less odor and a highly purified base, and the average particle size of emulsified particles should be 10 μm or less. Has disclosed an emulsified composition for hair dyes that suppresses the ammonia odor (Patent Document 2), but is still not sufficient in the hair dyeing effect. Moreover, although the hair coloring composition (patent document 3) containing peroxymonocarbonate ion is disclosed, although the hair dyeing effect improves, the subject remains in terms of the damage given to hair.

  The present invention has attracted attention as a problem existing in the prior art as described above, and its object is to have an unpleasant irritating odor and irritation on the skin while being excellent in hair dyeing effect. The object is to provide a hair cosmetic composition with less hair.

  Therefore, the present inventor has an excellent hair dyeing effect by including higher alcohol, higher fatty acid, alkali metal salt of aliphatic hydroxy acid, monoethanolamine, diethylenetriaminepentaacetic acid pentasodium as a chelating agent, The present inventors have found that a hair cosmetic composition with little unpleasant irritating odor during use and less irritation to the skin can be obtained, and the present invention has been completed.

  According to the present invention, it is possible to provide a hair cosmetic composition that has an excellent hair dyeing effect, can be used comfortably with little unpleasant irritating odor during use, and has little irritation to the skin.

  The hair cosmetic composition of the present invention is provided as a two-component type comprising a first agent containing an oxidative dye and a second agent containing an oxidizer, as is the case with hair dyes that are currently widely used. These dosage forms of the first agent and the second agent can be emulsion, cream, wax, foam or the like, and can also be aerosol.

  As higher alcohols in the present invention, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, aralkyl alcohol, behenyl alcohol, 2-hexyldecanol, isostearyl alcohol, 2-octyldodecanol, decyltetradecanol, oleyl alcohol, linoleyl Alcohol, linolenyl alcohol, lanolin alcohol, etc. are mentioned. Of these, myristyl alcohol, cetyl alcohol, stearyl alcohol, aralkyl alcohol, and behenyl alcohol are preferable, and cetyl alcohol and stearyl alcohol are more preferable. These may be contained alone or in combination of two or more.

  The content of the higher alcohol in the hair cosmetic composition of the present invention is not particularly limited, but is preferably 1 to 10% by mass, and more preferably 2 to 6% by mass. If it is less than 1% by mass, the hair dyeing effect is weak, and even if it is contained in excess of 10% by mass, no significant improvement in the hair dyeing effect is observed, which is uneconomical.

  Examples of the higher fatty acid in the present invention include lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, isostearic acid, hydroxystearic acid, oleic acid, undecylenic acid, linoleic acid, ricinoleic acid, and lanolin fatty acid. Of these, myristic acid, palmitic acid, stearic acid, and behenic acid are preferable, and palmitic acid and stearic acid are more preferable. These may be contained alone or in combination of two or more.

  Although the content of the higher fatty acid in the hair cosmetic composition of the present invention is not particularly limited, it is preferably 0.05 to 2.5% by mass, and more preferably 0.25 to 1.5% by mass. If the amount is less than 0.05% by mass, a sufficient irritating odor reducing effect cannot be expected. Even if the amount exceeds 2.5% by mass, no significant irritating odor reducing effect is observed, which is uneconomical.

  Examples of the alkali metal salt of the aliphatic hydroxy acid in the present invention include alkali metal salts such as glycolic acid, lactic acid, malic acid, citric acid, and tartaric acid. Of these, sodium malate and sodium citrate are preferable. These may be contained alone or in combination of two or more.

  The content of the alkali metal salt of the aliphatic hydroxy acid in the hair cosmetic composition of the present invention is 0.1 to 4% by mass, and preferably 0.5 to 2% by mass. If the amount is less than 0.1% by mass, a sufficient hair dyeing effect cannot be expected. If the amount exceeds 4% by mass, the skin may be irritated.

  The content of monoethanolamine in the hair cosmetic composition of the present invention is 1 to 5% by mass, preferably 1.5 to 4% by mass. If the amount is less than 1% by mass, a sufficient hair dyeing effect cannot be obtained.

  The content of diethylenetriaminepentaacetic acid pentasodium in the hair cosmetic composition of the present invention is 0.2 to 1.5 mass%, preferably 0.4 to 0.8 mass%. If the amount is less than 0.2% by mass, the hair dyeing effect cannot be expected. If the amount exceeds 1.5% by mass, the skin irritation increases.
