Description

  The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dye composition that improves the hair dyeing ability of a color treatment using a basic dye as a direct dye, while improving the background stain and also improving the hair feel after treatment.

  Compositions for hair dyeing are usually permanent hair dyes such as oxidative hair dyes using oxidative dyes, hair nail polish using direct dyes, semi-permanent hair dyes such as color treatments, color sprays for temporarily coloring hair, etc. It is roughly classified into hair temporary colorants (temporary hair dyes). Among these, semi-permanent hair dyes are inferior in hair dyeing power and hair sustainability compared with permanent hair dyes, but alkaline agents (first agents) and oxidizers (second agents) like oxidative hair dyes. It is known that there is little damage to the hair since no agent is used. A color treatment, which is a kind of semi-permanent hair dye, is a hair treatment that has a hair conditioning effect and at the same time exhibits a hair dyeing effect as a semi-permanent hair dye.

  As direct dyes used for semi-permanent hair dyes, in addition to traditional acid dyes, since April 2001, HC dyes that can be classified as basic dyes or nitro dyes can be used. For example, although the invention disclosed in Patent Document 1 below relates to a rinse-off hair coloring composition, a basic dye that is a cationic dye is exemplified as a coloring agent for hair (claims 8, 12, etc.). . Cationic surfactants are widely used as conditioning ingredients in hair treatments and other hair cosmetics.

  However, in the color treatment using the basic dye, the first problem is that the hair dyeing effect of the basic dye is slightly low. If the hair dyeing effect is increased by increasing the blending amount of the basic dye, there is a concern about background stains (staining of the basic dye on the skin). Furthermore, in the color treatment using a basic dye, there is a second problem of how to improve the hair dyeing power (hair dyeing effect) and an excellent conditioning effect at the same time. According to the research of the present inventor, if a large amount of a cationic surfactant is blended for the purpose of conditioning effect, there is a risk that hair dyeing with a basic dye may be inhibited.

  Therefore, the present invention solves the first and second problems in the color treatment using the basic dye and improves the hair dyeing ability of the basic dye, while suppressing the background stain, and after treatment. It is an object to be solved to provide a hair dye composition that also improves hair feel.

  In recent years, inorganic anionic fine particles called sea mud have attracted some attention as conditioning ingredients in hair cosmetics in relation to the means for solving such problems. For example, in the following Patent Document 2, a composition for hair dyeing (mainly oxidative hair dyeing) containing sea mud as component (A) and water-soluble collagen derived from vegetable protein hydrolyzate or fish as component (B), respectively. Agent), and the sea mud imparts an excellent conditioning effect to the hair (paragraph 0007). Patent Document 3 below discloses a hair cosmetic containing a seaweed extract as the component (A) and sea mud as the component (B). The hair cosmetic has an excellent moisturizing effect and flexibility on the hair. It has a conditioning effect such as an effect (paragraph 0001).

  The inventor of the present application formulated a basic dye that is a cationic as a direct dye used for color treatment, a cationic surfactant as a main conditioning component, and an anionic seawater as a conditioning component. When mud is blended, the above-mentioned first and second problems in the color treatment are solved, and a hair dye composition that can improve the hair dyeing power of basic dyes, suppress background stains, and improve hair feel. The present invention has been completed.

(Effect of the first invention)
In the hair dye composition of the first invention, since (C) component: a basic dye is contained as a direct dye, it is less likely to be dyed on the skin as compared with the case of containing other types of direct dyes, particularly minus. There is an advantage that the dye is easy to be dyed on damaged hair having a large amount of electrification.

  Also, for the problem that the hair dyeing effect of the basic dye is slightly low, the blending amount is increased to, for example, about 0.3 to 0.4% by mass to ensure sufficient hair dyeing power. Can do. Usually, when the blending amount of the basic dye is increased to such a level, the background stain based on the dyeing of the basic dye on the skin becomes conspicuous. However, since the hair dye composition of the first invention contains the component (A): sea mud, the background dirt is effectively prevented. The reason for this is not clearly understood, but it is presumed that sea mud, which is an anionic inorganic fine particle, adsorbs a cationic basic dye.

  Furthermore, since the hair dye composition of the first invention contains the component (B): a cationic surfactant, a certain improvement in hair feel can be realized based on the conditioning effect. In order to further enhance the effect of improving the hair feel, if the amount of the cationic surfactant is increased to, for example, about 4 to 5% by mass, hair dyeing with a basic dye may be usually inhibited. . However, in the hair dye composition of the first invention, since the conditioning effect by the component (A): sea mud is also obtained, the effect of improving the excellent hair feel can be obtained without particularly increasing the amount of the cationic surfactant. Is secured.

  From the above points, while the hair dye composition of the first invention improves the hair dyeing ability of the basic dye, it can suppress background stains and improve the hair feel after treatment.

(Effect of the second invention)
According to the hair dye composition of the second invention, the effect of improving the hair dyeing ability of the basic dye in the hair dye composition of the first invention is particularly prominent. This is because alkylamidoamine-based cationic surfactants, in addition to general conditioning effects as cationic surfactants, have been studied by the inventors of the present application, for example, other types of cationic surfactants such as quaternary amine-based surfactants. This is because it has been found that the effect of improving the hair dyeing power of the basic dye is particularly large compared to the agent.

(Effect of the third invention)
As defined in the third invention, the content of component (A) in the hair dye composition: sea mud is particularly preferably in the range of 0.05 to 1% by mass. By making content of (A) component into this range, the compounding effect of (A) component can be ensured more favorably, and dyeing of the basic dye to the hair can be favorably secured.

(Effect of the fourth invention)
(D) component prescribed | regulated to 4th invention: Since cationized hyaluronic acid shows conditioning effects, such as gloss of hair based on the outstanding moisturizing effect, the improvement effect of the hair touch in the hair dye composition of this invention is still stronger Become.

(Effect of the fifth invention)

(Hair dyeing power immediately after hair dyeing)
1 g of the hair dye composition according to each example and each comparative example was respectively applied to 1 g of a human hair bundle mixed with white hair, and allowed to stand for 10 minutes, followed by washing with water, whereby the hair dyeing treatment for the human hair bundle was completed.

  Immediately after the completion of the hair dyeing treatment, 10 panelists visually observed the degree of dyeing of human hair bundles, which was very good (5 points), excellent (4 points), and somewhat excellent (3 points). Evaluation was made on a five-point scale: bad (2 points) and bad (1 point). The average value of the scoring results of each paneler was rounded to the first decimal place, and the evaluation score for each example was calculated. The evaluation results are shown in the column of “dyeing power immediately after hair dyeing” in each table.

(Dyeing power after continuous dyeing)
After performing the hair dyeing treatment after shampooing on each human hair bundle according to each Example and each Comparative Example in which the hair dyeing treatment described in the above-mentioned "Dyeing power immediately after hair dyeing" was performed, the human hair bundle By repeating the cycle of drying with a hair dryer four times, continuous hair dyeing treatment for human hair bundles was completed.

  Immediately after the completion of the above-mentioned continuous hair dyeing treatment, 10 panelists visually observe the degree of dyeing of human hair bundles, which is very good (5 points), excellent (4 points), and somewhat excellent (3 points). Evaluation was made on a five-point scale, slightly bad (2 points) and bad (1 point). The average value of the scoring results of each paneler was rounded to the first decimal place, and the evaluation score for each example was calculated. The evaluation results are shown in the column of “dyeing power immediately after hair dyeing” in each table.

(Applying firmness and elasticity to hair when dry)
After drying the human hair bundle that has been subjected to the hair dyeing treatment described in the above section of “Dyeing power immediately after hair dyeing” with a hair dryer, 10 panelists gave the hair to the hair bundle. The degree was evaluated by touch, and was evaluated in four stages: very good (4 points), good (3 points), slightly bad (2 points), and bad (1 point). The average value of each paneler's scoring result is calculated to the first decimal place. If the average value is 3.6 points or more, “◎”, if the average value is 2.6 points or more and 3.5 points or less. If “◯”, the average value was 1.6 points or more and 2.5 points or less, “Δ” was evaluated, and if the average value was 1.5 points or less, “X” was evaluated. The evaluation results are shown in the column “Applying firmness and stiffness to the hair when dry” in each table.

(Give smoothness to dry hair)
After the human hair bundle that has been subjected to the hair dyeing treatment described in the section “Hair dyeing power immediately after hair dyeing” is dried with a hair dryer, 10 panelists added the smoothness to the human hair bundle. Was evaluated by touch, and was evaluated in four stages: very good (4 points), good (3 points), slightly bad (2 points), and bad (1 point). The average value of each paneler's scoring result is calculated to the first decimal place. If the average value is 3.6 points or more, “◎”, if the average value is 2.6 points or more and 3.5 points or less. If “◯”, the average value was 1.6 points or more and 2.5 points or less, “Δ” was evaluated, and if the average value was 1.5 points or less, “X” was evaluated. The evaluation results are shown in the column of “Granting smoothness to hair when dry” in each table.
