Description

[Technical field]

[0001] The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dye composition which contains a direct dye and is used by being discharged in the form of a foam from a non-aerosol foamer container. [Background technology]

[0002] Hair coloring agents are broadly classified into permanent hair dyes such as oxidation hair dyes that use oxidation dyes, bleaches 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 oxidation hair dyes that contain oxidation dyes are widely used because they can provide excellent hair dyeing effects, but they have the disadvantage of placing a heavy burden on the hair and scalp because they generally contain oxidizing agents and alkaline agents.

[0003] In contrast, semi-permanent hair dyes are hair dye compositions containing direct dyes such as basic dyes, acid dyes, and HC dyes, and examples of such products include color treatments that simultaneously exhibit hair dyeing and treatment properties, and color shampoos that simultaneously exhibit hair dyeing and cleansing properties, and have the advantage of being less stressful on the hair and scalp. Among these, color shampoos not only function as cleansing agents to simply remove dirt from the hair and scalp, but also have the convenience of gradually adsorbing direct dyes such as basic dyes and HC dyes onto the hair while washing the hair on a daily basis, thereby dyeing the hair.

[0004] In recent fashion color trends, a wide range of hair colors, from bright hair colors such as primary colors to dull hair colors such as dark tones and gray tones, are becoming increasingly popular. At the same time, interest is also growing in complementary colors for hair color fading caused by repeated daily hair washing, and hair dye compositions such as color shampoos are often used as a means of complementary colors. Compared to oxidative hair dyes, they do not contain oxidizing agents or alkaline agents, 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. In particular, bright hair colors such as primary colors, dull hair colors such as gray tones, and blue tones tend to be disturbed by the yellowish color derived from the melanin pigment of the hair itself that has been lightened by bleaching, etc., during the fading process, so hair dye compositions such as color shampoos tend to be used for complementary colors.

[0005] In addition, there are various types of shampoo, such as a type in which the liquid preparation is directly taken by hand and lathered on the hair and applied, and a type in which the liquid preparation is discharged from a non-aerosol foamer container and applied to the hair, and the same is true for color shampoo. When the liquid preparation is directly taken by hand and lathered on the hair and applied, friction occurs on the hair due to the act of lathering, and a certain amount of physical stress is applied. On the other hand, when the liquid preparation is discharged from a non-aerosol foamer container and applied to the hair, there is no need to lather, so there is no friction, and there is an advantage in that the physical stress on the hair during application can be reduced while dyeing (complementing the color), and demand has been increasing in recent years.

[0006] As such a color shampoo, Patent Document 1 proposes a hair dye composition that contains a basic dye, an HC dye, or an acid dye, and that is foamed when used to dye the hair. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2023-6942 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, the hair dye composition in Patent Document 1 only mentions dyeability, and does not consider the necessary functions of a shampoo, such as foam quality, foaming ability, cleansing ability, and feeling of use when rinsed off, such as squeaking. In addition, there remains a problem with dye uniformity, which is important for hair dye compositions such as color shampoos.

[0009] Therefore, an object of the present invention is to provide a hair dye composition which has good foam quality and foaming properties, excellent detergency, no squeaking when rinsed off, and excellent dye leveling properties. [Means for solving the problem]

[0010] As a result of extensive investigation, the present inventors have A hair dye composition containing a direct dye and discharged in the form of a foam from a non-aerosol foamer container, (A) Fatty acid alkanolamide (B) one or more selected from polyoxyethylene hydrogenated castor oil and polyoxyethylene alkyl ether (C) Amphoteric surfactant (D) Anionic surfactants (E) One or more selected from cationic polymers and amphoteric polymers a hair dye composition comprising the above-mentioned components (A) and (B), the content of the above-mentioned components (B) and (C), the content of the above-mentioned components (C) and (D), the content of the above-mentioned components (D) and (E) being 0.1 to 3% by mass, 0.1 to 2.5% by mass, 1 to 15% by mass, 0.1 to 3% by mass, and 0.1 to 2.5% by mass, respectively, and having a pH in the range of 4 to 6.8.
