Description

[Technical Field]

[0001] The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dye composition containing a basic dye or an HC dye, or both. [Background technology]

[0002] Hair coloring products are broadly classified into permanent hair dyes such as oxidative hair dyes that use oxidative dyes, bleaching agents that lighten hair, semi-permanent hair dyes that use direct dyes, and temporary hair dyes that temporarily color hair. Of these, permanent hair dyes such as oxidative hair dyes that contain oxidative dyes are widely used because they exhibit excellent hair coloring effects, but they generally contain oxidizing agents and alkaline agents, which has the disadvantage of being harsh on the hair and scalp.

[0003] In contrast, semi-permanent hair dyes are hair dye compositions containing direct dyes such as basic dyes, acid dyes, and HC dyes. One type of semi-permanent hair dye is a color treatment that simultaneously provides both hair dyeing and conditioning effects. Because cationic surfactants are commonly used in these color treatments to provide conditioning effects, when used in combination with acid dyes, the cationic surfactant and acid dye may aggregate, reducing the dyeing power. For this reason, basic dyes and HC dyes, which do not significantly reduce dyeing power when used in combination, are mainly used as direct dyes in color treatments.

[0004] By combining these multiple direct dyes, the range of colors becomes more diverse, and in recent fashion color trends, not only bright primary colors but also muted colors such as dark tones and grays are gaining popularity. Furthermore, hair dye compositions such as color treatments do not contain oxidizing agents or alkaline agents compared to oxidative hair dyes, so they can reduce damage to the hair and scalp and can be used frequently, which has led to an increase in demand in recent years. On the other hand, hair dyes produced with these direct dyes have the disadvantage of fading quickly with washing (poor color fastness), unlike those produced with oxidative dyes.

[0005] Patent Document 1 proposes a hair dye composition containing basic dyes and HC dyes as such a color treatment, which provides a moist, smooth, and manageable finish, as well as good smoothness when rinsing and long-lasting feel. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2020-132606 [Overview of the project] [Problems that the invention aims to solve]

[0007] However, the hair dye composition described in Patent Document 1 had a problem with the colorfastness after dyeing, as it faded quickly after washing. Furthermore, there was still room for improvement in its user experience.

[0008] Therefore, the object of the present invention is to provide a hair dye composition that is excellent in durability, smoothness when rinsing, a smooth finish, and a manageable finish. [Means for solving the problem]

[0009] As a result of intensive studies, the inventor has found that a hair dye composition containing a direct dye, an oily component (excluding silicone oil) that is liquid at 25°C, a cationic surfactant, a higher alcohol, and a polyhydric alcohol, (A) Dimethyldiallylammonium chloride·acrylamide copolymer (B) Methyl polysiloxane having a kinematic viscosity at 25°C of 10 mm ,
