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, shampoo, hair rinse, hair treatment, and hair foam which is excellent in lasting, moisturizing, soft and lubricating properties. The present invention relates to a hair cosmetic which is excellent in hair dyeing properties and the like, without transferability in the case of hair dyes, especially hair dyes.

[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. However, these conventional hair cosmetics are excellent in the feel of hair, that is, moist feeling and smoothness, which are conditioning effects, but have a drawback that flexibility is not sufficient. That is, there is flexibility in a leaking state, but almost lost in a dry state.

[0003] Therefore, for the purpose of solving such a drawback, oils and fats such as higher alcohols, glycerides and liquid paraffin have been 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. In addition, hard hair often has poor cohesion due to the high elasticity of the hair.
Meeting consumer demands has been difficult. Further, for the purpose of continuously imparting moisturizing and imparting flexibility to the inside, there has been proposed a compound containing α-hydroxycarboxylic acid (Japanese Patent Application Laid-Open Nos. 6-172130 and 6-17231). Further, a composition in which a silicone compound is blended for imparting lubricity has been proposed (JP-A-4-230616 and JP-A-5-4907). However, none of the components alone simultaneously satisfies the internal sustained moisture retention and lubricity.

Further, as a means for improving the flexibility of hair, a hair conditioning composition using a combination of a 2-hydroxy fatty acid having 6 or more carbon atoms and a conditioning component has been proposed (for example, JP-A-3-4860).
No. 7, JP-A-3-48609). However, they have not been enough to maintain the effect of flexibility. Moreover, in order to sufficiently achieve the two purposes, two or more components having different functions must be used in combination, and when two or more components are combined, two components having different polarities are used. The addition of the above-mentioned components causes a problem in the stability of the obtained hair cosmetic. In other words, it was difficult to maintain the effects of moisturizing, flexibility and lubricity continuously and simultaneously.

[0005] 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, in many cases, a satisfactory hair dyeing effect cannot be obtained by a single treatment unless the treatment time is lengthened or humidified. In addition, when the acid dye hair dye is applied to the hair and washed off with shampoo, the washing liquid has such a dark color that the washing liquid is unpleasant,
After the shampoo, the dye solution adheres to the towel or pillow cover,
It has a drawback that when hair is wet due to sweating or rainfall, it is transferred to clothing or the like.

In order to improve such disadvantages as dyeing property and colorfastness, specific acid dyes are used, and glycolic acid and / or pyrrolidone carboxylic 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.

[0007] A hair dye composition for making gray hair less noticeable by using it multiple times in a usage method such as a hair rinse 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.

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a hair cosmetic composition which gives the hair a long lasting lubrication property with excellent moisturizing properties and flexibility, and improves the unity of the hair. Aim. Further, when the hair cosmetic is used as a hair dye, the present invention significantly suppresses the color of the shampoo washing solution at the time of hair dyeing, and has no transferability to clothing, skin, etc., and has a vivid color tone.
