Description

[Technical field]

[0001] The present invention relates to a hair dye composition, and more particularly to a hair dye composition having excellent high-temperature stability of a direct dye. [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 that contain direct dyes such as basic dyes, acid dyes, and HC dyes, and demand for them has been increasing in recent years as they cause less damage to hair and provide good color development.

[0004] Increased demand has led to long-distance transportation and long-term storage, which means that direct dyes are often exposed to high-temperature conditions during long-term storage. This can reduce the stability of direct dyes, making it a challenge to maintain the high-temperature stability of direct dyes.

[0005] Conventionally, as in Patent Document 1, it has been proposed that antioxidants such as ascorbic acid are effective in improving the stability of direct dyes, and among them, resorcin is particularly effective. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-132776 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, resorcin and ascorbic acid could not provide sufficient effect on the high temperature stability of direct dyes.

[0008] Therefore, an object of the present invention is to provide a hair dye composition which exhibits excellent high-temperature stability of a direct dye. [Means for solving the problem]

[0009] The present inventors have discovered that a hair dye composition containing a direct dye, which is characterized by containing (A) an oil-soluble antioxidant, can provide a hair dye composition having excellent high-temperature stability of the direct dye, and have thus completed the present invention. Effect of the Invention

[0010] The present invention provides a hair dye composition having excellent high-temperature stability of a direct dye. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

EXAMPLES

[0033] The present invention will be described in more detail below by way of examples, but these are not intended to limit the present invention in any way.

[0034] 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.

[0035] In the evaluation tests shown in this specification, the "high temperature stability of direct dyes" was evaluated.

[0036] "High temperature stability of direct dyes" 120 g of the hair dye composition according to each Example and Comparative Example was placed in a sample bottle (Food 140: manufactured by Daiichi Glass Co., Ltd.) and stored in a thermostatic chamber at 50° C. for 3 months. Each stored hair dye composition was returned to 20° C. and subjected to high performance liquid chromatography (HPLC) measurement. The residual percentage of the direct dye was calculated by comparing with the results of the standard substance, and the following evaluation was made according to the residual percentage. <Evaluation criteria> ◎: Residual rate of direct dye is 90% or more ○: Residual rate of direct dye is 85% or more but less than 90% △: Residual rate of direct dye is 80% or more but less than 85% ×: Residual rate of direct dye is less than 80%

[0037] The measurement conditions for the above HLPC are as follows. HPLC equipment: LC-20A (Shimadzu Corporation) Eluent: water / methanol = 7 / 3 (volume ratio), isocratic Flow rate: 1.0mL / min Measurement wavelength: HC blue 2:550nm 4-Hydroxypropylamino-3-nitrophenol: 480 nm Column: Mightysil RP-18GP (Kanto Chemical Co., Ltd., column diameter 4.6 mm x length 250 mm, particle diameter 5 μm, pore size 14 nm) Column temperature: 40℃ Preparation of sample solution for measurement: Each hair dye composition was dissolved in a mixed solvent of water / methanol (7 / 3 (volume ratio)) and filtered with a syringe filter. Standard substance: Each direct dye was dissolved in a mixed solvent of water / methanol (7 / 3 (volume ratio)) to the same concentration as the measurement sample solution, and then filtered through a syringe filter. Sample injection volume: 20.0 μL

[0039] It was confirmed that good results were obtained regarding the high-temperature stability of the direct dye from Examples 1 to 9 shown in Table 1. It was confirmed from Comparative Examples 1 to 3 that good results were not obtained regarding the high-temperature stability of the direct dye when no antioxidant was used or when water-soluble antioxidants such as resorcin or ascorbic acid were used.
