Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a novel hair cosmetic, and more particularly, to a hair dye excellent in lasting flexibility and lubricity, a shampoo, a hair rinse, a hair treatment, a hair foam, a hair gel and the like, particularly a hair dye. The present invention relates to a hair cosmetic which is excellent in hair dyeability and the like, without transferability.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics include mono- or di-linear long-chain alkyl quaternary ammonium salts and mono- or di-branched long-chain alkyl quaternary ammonium salts in order to improve the feel of hair. Of a cationic surfactant.

[0003] However, these conventional hair cosmetics are excellent in the feel of the hair, that is, the conditioning effect, such as moist feeling and smoothness, but have the disadvantage that the flexibility is not sufficient. That is, there is flexibility in a leaking state, but almost lost in a dry state. Therefore, for the purpose of solving such disadvantages, higher alcohol, glyceride,
Oils and fats such as liquid paraffin were used in combination. These leave hydrophobic molecules on the surface of the hair to lower the surface tension and impart a soft feel to the skin. Therefore, it is difficult to maintain flexibility continuously. Hard hair often has poor cohesion due to the high elasticity of the hair, but it has been difficult to satisfy the demands of consumers with conventional surface measures. As means for improving the flexibility of hair, hair conditioning compositions using a combination of a 2-hydroxy fatty acid having 6 or more carbon atoms and a conditioning component have been proposed (for example, JP-A-3-48607, JP-A-3-48607). 3-48609). However, they have not been enough to maintain the effect of flexibility. In other words, it has been difficult to maintain the effects of both flexibility and lubricity continuously.

[0004] On the other hand, hair dyes containing acid dyes and natural dyes are widely used at home and in beauty salons because they have less damage to hair than other hair dyes. However, when the acid dye hair dye is applied to the hair and then washed away with shampoo, the washing liquid has an unpleasantly unpleasant dye color, and the dye solution adheres to the towel or pillow cover after shampooing, or causes perspiration or perspiration. It has the disadvantage that when hair is wet due to rainfall, it is transferred to clothing and the like.

In order to improve such disadvantages as dyeing property and colorfastness, a specific acid dye is used, and glycolic acid and / or pyrrolidonecarboxylic acid and / or their alkali metal salts and alkaline earths are used. A hair dye composition using a combination of a metal salt and an amine salt has also been proposed (JP-A-6-2).
No. 98630), which is not yet satisfactory in terms of transferability.

[0006] A hair dye composition for making gray hair less noticeable by using it multiple times in a use method such as a hair rinse, which contains an acid dye and an organic solvent and has a pH of 2.0
To 4.5, a salt of an organic acid or the like is blended, and the buffer capacity is set to 0.1.
A hair dye composition having an amount of from 0.1 to 0.2 gram equivalent / l has been proposed (Japanese Patent Application Laid-Open No. 5-78228). The compound containing sodium citrate and sodium lactate is still unsatisfactory in terms of transferability and texture.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hair cosmetic composition which provides hair with excellent flexibility and lubricity to improve the unity of the hair.
Further, the present invention, when the hair cosmetic is a hair dye, the color of the shampoo washing solution at the time of hair dyeing is significantly suppressed,
To provide a hair coloring material which has no dye transferability to clothing, skin, etc., can dye hair in a vivid color tone, has excellent dyeing properties, and has excellent flexibility and combability after hair dyeing. With the goal.

[0008]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, by blending an aliphatic polycarboxylic acid or a salt thereof, the flexibility is continuously maintained. And can impart lubricity to the hair,
In addition, when a hair dye was used, it was found that discoloration to a washing solution at the time of hair dyeing could be suppressed and the dye transfer property could be improved, and the present invention was completed.

That is, according to the present invention, there is provided a hair cosmetic comprising 1 to 20% by weight of an aliphatic polycarboxylic acid or a salt thereof. Further, according to the present invention, there is provided the hair cosmetic, wherein the hair cosmetic is a hair dye, and according to the present invention, further, the following general formula (1):

Embedded image (In the formula, R ² represents a hydrogen atom, an alkyl group, or an alkoxyl group. X represents a linear or branched alkylene group or alkenyl group having 1 to 4 carbon atoms, and may contain an ether bond. .P represents 0 or 1.), wherein the hair cosmetic (hair dye) is provided.
