Description

Description Hair dye Technical field

The present invention relates to a hair dye. In particular, it is excellent in stability, feeling in use (smoothness), and dyeability, and it also relates to a hair acid hair dye that does not require much time and effort after washing. Background art

Hair dyes for dyeing hair are widely used, for example, as “white hair dye” and “fashionable dye”. This hair dye naturally contains a coloring agent for coloring the hair to a desired color, and as such a coloring agent, an “acid dye” which exhibits the best hair dyeing effect in the acidic region is used. It is mentioned as one of the most suitable because of its excellent safety. In particular, azo-based acid dyes are mainly used as coloring agents of “semi-permanent hair dyes” intended to sustain the hair coloring effect semi-permanently, and the need for acid dyes in hair dyes is great.

The "acid hair dye", which is a hair dye using such an acid dye as a coloring agent, needs to adjust the pH range to a strongly acidic range of 1.5 to 4.5 at the time of use. In addition to the above-mentioned acid dyes, natural dyes are also used in terms of dyeability and color, but when natural dyes are blended, their use in the acidic region is desirable in terms of mildness to hair and the like. Those which can exhibit a dyeing effect in such an acidic region are preferably used. In such an acidic region, it is generally practiced to add a thickener so that the strongly acidic hair dye does not sag during use and does not come in contact with the hair dye. But force ^s et al, thickeners usable in p H of the strong acid region is rather limited, yet even thickeners are said to be used in a strongly acidic region, thickeners you formulated hair dye Are not always completely satisfactory. That is, xanthan gum can be mentioned as the main slimming agent currently used for acid-based hair dye (Japanese Patent Publication No. 2-32253), and in addition to xanthan gum, Ben as a improver. A system in which tonite and z or a crosslinkable sodium polyacrylate are used in combination has been used (Japanese Patent Application Laid-Open No. 5-51099).

The hair dye containing xanthan gum, which has been known to date, is stable at pH 4.5 or higher, but exerts a dyeing effect, but its viscosity is strong in the strongly acidic region of pH 1.5 to 4.5. Changed significantly and there was a problem with stability. In addition, it can not be denied that it has poor fluidity, and when applied from the hand to the head, it tends to be clumped down and difficult to stretch in the hair. Furthermore, it was accompanied by a sticky feeling of use, and it was not satisfactory for the feeling of use.

Therefore, as described above, a system in which bentonite and Z or crosslinkable polyacrylic acid was used in combination with xanthan gum was found, and the above-mentioned fluidity was improved, but problems still remain in terms of stability. Furthermore, there are problems such as time-consuming washing after use.

However, for products that are applied to the hair and washed away, it is prepared with a combination of a cationic surfactant such as an alkyltrimethyl ammonium salt and a long chain alkyl alcohol in order to impart smoothness to the hair and to reduce shortness. are Rinsugeru force ^s formulations conventionally being. However, in the case of an acid hair dye, since the dye is anionic, the presence of the cationic component forms an ionic complex, resulting in an insoluble precipitate in the formulation. Therefore, it is not possible to add cationic rinse gel to the acid hair dye, and as a result, the feeling of use of the conventional acid hair dye has problems with squeezing at the time of rinsing and hair dry after drying.

The present invention has been made in view of the above circumstances, and is stable even in a strongly acidic region (p H 1 .5 to 4.5) that exerts the coloring effect of an acid dye, and has an appropriate viscosity, Furthermore, it aims to provide a hair dye that is excellent in feel on use and does not require time-consuming washing after use.
