DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair coloring composition having excellent skin safety, dyeing properties, hair damage preventing properties, storage stability and the like.

[0002]

2. Description of the Related Art So-called acidic hair dyes (semi-permanent hair dyes) have been known which have improved the disadvantages of oxidative hair dyes (permanent hair dyes). Conventional oxidative hair dyes have an action of selectively dyeing hair by distinguishing between hair and skin, and have excellent dyeing characteristics such as high dyeing fastness, but are intense at the time of hair dyeing. With chemical reaction, skin safety is inferior, even if hair protection agent is added, it causes damage to hair,
There are drawbacks in that the hair after dyeing is stiff, the strength of the hair is reduced, the hair is liable to be cut or split, and the property for preventing hair damage is also unsatisfactory.

[0003] In order to solve these drawbacks, acid hair dyes have been developed in which various organic solvents, hair dyeing assistants, hair protecting agents and the like are blended. Did not. That is, these acidic hair dyes usually contain an acid dye such as a tar dye and an organic solvent such as ethanol, benzyl alcohol, N-methylpyrrolidone or a hair dyeing aid for the purpose of enhancing the dyeing property. % By weight, and further, an organic acid such as tartaric acid, citric acid, lactic acid, and glycolic acid is added to adjust the pH value of the composition to an acidic side of 1.5 to 4.5.

[0004] In the case of such a composition for dyeing hair, the skin safety and the property for preventing hair damage are somewhat improved, but they are not sufficient, and the hair and skin are dyed without distinction, and the hair is dyed. It was poor in dyeability and poor in dyeing properties. In addition, some measures have been taken to improve the dyeing properties, for example, by blending ammonium thioglycolic acid salt and sodium sulfite, etc. The stability was poor.

[0005] Next, there is known a composition called color rinse, which suppresses the hair dyeing effect and increases the frequency of use to maintain the dyeing of hair. The purpose of this composition is to substantially reduce the amount of the tar dye to combine the effects of other hair treatment agents and the hair dyeing effect, and the hair dyeing effect is low. Therefore, by increasing the frequency of use,
There were drawbacks in skin safety and hair damage prevention properties, and hair and skin were not distinctly dyed, and the dyeing properties were not satisfactory. That is, there is a need for a hair coloring composition having excellent properties such as skin safety, dyeing properties, hair damage preventing properties, and storage stability.

[0006]
