Description

  The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dye composition that has excellent dyeing properties for hair, is stable over time, and does not cause dripping and has excellent usability.

  Hair dyes include temporary hair dyes, semi-permanent hair dyes, permanent hair dyes, and the like, all of which are widely used. Permanent hair dyes are widely used because of their excellent hair dyeing power, oxidized hair dyes comprising a first agent containing an oxidative dye and a second agent containing an oxidant such as hydrogen peroxide. Yes. However, oxidative hair dyes are irritating because of the alkaline agent they contain, and are prone to hair damage, and the oxidation dye precursors may cause allergies to the human body and cannot be used depending on the constitution. There is.

  Temporary hair dyes can be washed off with a single shampoo, so they are used in situations where you only want to enjoy fashion for a day. . Therefore, as an alternative hair dye composition, acidic hair dyes of semi-permanent hair dyes that can withstand 15 to 30 hair washings are widely used. Acid hair dyes do not contain alkaline agents, so hair damage is unlikely to occur, but they only impregnate dyes on the surface of the hair, so there is a problem that color durability is inferior to that of oxidized hair dyes. there were. In addition, in order to obtain a strong hair dyeing power, the hair dye composition needs to be strongly acidic, so that there is a drawback that stability is difficult.

  For this reason, attempts have been made to maintain stability by combining multiple thickeners, but depending on the choice of thickener, there is a problem that the hair coloring power is reduced or the hair is poorly stretched and difficult to use. was there.

So far, means for obtaining an acidic hair dye having good usability by selecting a thickener has been disclosed, but means using gum arabic (Japanese Patent Laid-Open No. 6-80540), methyl cellulose, hydroxypropyl methyl cellulose, hydroxy A thickener was used in either one or two or more of ethylmethylcellulose and a means using xanthan gum (Japanese Patent Laid-Open No. 8-225435) and a means using oxyalkylenated xanthan gum (Japanese Patent Laid-Open No. 2001-240521). At present, no acid hair dye has been invented that sufficiently satisfies both elongation to hair and long-term stability.
