Description

[Technical field]

[0001] The present invention relates to a hair dye composition, and more particularly to a hair dye composition which has good dyeing properties, fastness and manageability of hair, and does not make hair sticky. [Background technology]

[0002] In recent years, hair coloring agents, which allow you to easily change your hair color, have been used by many people. There are various types of hair coloring agents, such as permanent hair dyes, semi-permanent hair dyes, bleaches, and temporary coloring agents, and they are used according to the needs of each person.

[0003] Although semi-permanent hair dyes do not last as long as permanent hair dyes, they cause less damage to the hair and are easy to use, so they are currently used by many people.

[0004] Semi-permanent hair dyes are classified into hair manicures using acid dyes and color treatments using basic dyes or HC dyes. Hair manicures have excellent dyeing properties, but they also tend to stain the skin. In addition, benzyl alcohol is used to penetrate the acid dye into the hair, which causes discomfort to the user due to the characteristic solvent smell, and causes stiffness in the hair after use.

[0005] On the other hand, color treatments have a lower dyeing ability than hair manicures, but they do not emit an unpleasant solvent odor. In addition, because they are treatments, they can give hair manageability and a moist feeling after use, so there is high demand from consumers and various color treatments have been proposed so far.

[0006] For example, Patent Document 1 discloses a hair dye composition containing glycerin, 1,3-butylene glycol, and a basic dye, which has good dyeability, suppresses skin staining, and has good stability of the basic dye over time. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2019-64947 A Summary of the Invention [Problem to be solved by the invention]

[0008] The hair dye composition of Patent Document 1 is disclosed to have good dyeing properties, but fastness has not been considered, leaving room for improvement.Furthermore, the finish as a treatment has not been considered, leaving the possibility of insufficient hair management.

[0009] The present invention is therefore intended to solve the above problems. That is, an object of the present invention is to provide a hair dye composition which is excellent in dyeability, fastness and hair manageability, and does not make hair sticky. [Means for solving the problem]

[0010] The present inventors discovered that the above problems could be solved by adding polypropylene glycol and a sugar alcohol to a hair dye composition containing one or more types selected from basic dyes or HC dyes, and thus completed the present invention.

[0011] That is, the present invention provides a hair dye composition containing one or more dyes selected from basic dyes and HC dyes, (A) Polypropylene glycol (B) Sugar alcohol The present invention provides a hair dye composition comprising: Effect of the Invention

[0031] In the evaluation tests shown in the present specification, the components contained in the hair dye composition and their contents were changed in various ways. The units showing the contents of each component are all mass %, and these were prepared by a conventional method.

[0032] In the evaluation test methods shown in this specification, "dyeability," "fastness," "hair manageability," and "non-stickiness of hair" were evaluated by the following methods.

[0033] "Stainability" Approximately 1 g of hair bundle (100% human gray hair, BM-WA, manufactured by Bealux Co., Ltd.) was washed with 0.3 g of shampoo (GREEN BOTTLE Botanical Rich Shampoo Luxury Bergamot Scent, manufactured by Dariya Co., Ltd.), lightly dried with a towel, and 0.5 g of the hair dye composition obtained in the Examples and Comparative Examples was evenly applied. After leaving it for 5 minutes, it was rinsed with water and dried with a hair dryer to prepare a hair bundle for evaluation. The "dyeability" was visually observed by 10 panelists and evaluated according to the following evaluation criteria, and the total score was used as the evaluation result.

[0034] <Evaluation criteria for dyeability> Very dark: 3 points Darkly dyed: 2 points Lightly stained: 1 point Almost no staining: 0 points

[0035] <Evaluation results of dyeability> 5:25 points~30 points 4:20 points~24 points 3:15 points to 19 points 2:10 points to 14 points 1: 0 points ~ 9 points

[0036] "Robustness" Two hair bundles for evaluation obtained in the hair dyeing process of the dyeability evaluation test above were prepared, one of which was wetted with water, washed with 0.3 g of shampoo (GREEN BOTTLE Botanical Rich Shampoo Luxury Bergamot Scent, manufactured by Dariya Co., Ltd.), lightly squeezed out the water with a towel, and dried with a hair dryer. This process was repeated five times, and the degree of color fading of the evaluation hair bundle before and after washing was visually observed by 10 panelists and evaluated according to the following evaluation criteria, and the total score was used as the evaluation result.

[0037] <Evaluation criteria for robustness> Almost no color loss compared to the evaluation hair bundle before washing: 3 points Slight color fading compared to the evaluation hair bundle before washing: 2 points Discoloration is noticeable compared to the hair bundle used for evaluation before washing: 1 point Severe color fading compared to the hair bundle used for evaluation before washing: 0 points

[0038] <Robustness evaluation results> 5:25 points~30 points 4:20 points~24 points 3:15 points to 19 points 2:10 points to 14 points 1: 0 points ~ 9 points

[0039] "Hair manageability" and "non-sticky hair" A wig (100% human black hair, Queen Cut No. 775N, Beaulux Co., Ltd.) was washed with shampoo (GREEN BOTTLE Botanical Rich Shampoo, Luxury Bergamot Scent, Dariya Co., Ltd.), lightly dried with a towel, and 25 g of the hair dye composition obtained in the Examples and Comparative Examples was applied, left to stand for 5 minutes, rinsed with water, and dried with a hair dryer to prepare a wig for evaluation. "Hair manageability" and "non-stickiness of hair" were evaluated sensorily by 10 panelists according to the following evaluation criteria, and the total score was used as the evaluation result.

[0040] <Criteria for evaluating hair manageability> Cohesive: 3 points Somewhat cohesive: 2 points Not very organized: 1 point Disorganized: 0 points <Hair manageability evaluation results> 5:25 points~30 points 4:20 points~24 points 3:15 points to 19 points 2:10 points to 14 points 1: 0 points ~ 9 points
