Abstract

PROBLEM TO BE SOLVED: To provide a hair dye with high hair-dyeing properties.SOLUTION: A hair dye according to the present invention comprises (a) dye, and (b) at least one selected from phenylethyl alcohol, eugenol, vanillin, camphor, caffeine, cinnamon oil and clove oil.SELECTED DRAWING: None

Description

  The present invention relates to a hair dye excellent in dyeability.

Hair dyes are roughly classified into temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes from the viewpoint of performance.
These hair dyes have a function of coloring hair, but are required to have higher hair dyeing properties. For example, Patent Document 1 describes the use of an organic solvent such as benzyl alcohol in order to improve the hair dyeing property in this way.

  However, such organic solvents are concerned about adverse effects on the human body, and there is a demand for hair dyes having high hair dyeing power using natural materials that are considered to have less influence on the human body.

JP-A-7-118130

  An object of this invention is to provide the hair dye with high hair dyeing property.

  The hair dye of the present invention comprises (a) a dye, and (b) at least one selected from phenylethyl alcohol, eugenol, vanillin, camphor, caffeine, cinnamon oil and clove oil.

  ADVANTAGE OF THE INVENTION According to this invention, a hair dye with high hair dyeing property can be provided.

  Hereinafter, embodiments of the present invention will be described.

The dosage form of the hair dye of the present invention is not particularly limited. For example, it can be a cream, liquid, gel, emulsion, spray, aerosol type or the like. Of these, the aerosol type is preferable. In addition, when it is set as a multi-component type hair dye, each dosage form of a multi-component type may be the same, or may differ. The hair dye of the present invention can further contain known components necessary for formulation, which can be selected according to the type of dosage form.
What is necessary is just to set suitably as a well-known component required for formulation for every kind of dosage form. For example, an aerosol type dosage form may be manufactured by filling a pressure-resistant container with a compressed gas, a surfactant, a thickener, and / or a liquefied gas in an anaerobic atmosphere. The compressed gas used here is preferably nitrogen, carbonic acid, argon or the like. Other dosage forms may be prepared according to known methods.

[Hair dyeing method]
In the hair dyeing method of the present invention, the hair dye of the present invention is applied to hair, left for a certain period of time, and then washed away. In the case of a single agent type, one agent is used as it is, and in the case of multiple agents, it may be applied to the hair simultaneously or separately. In the case of a multi-drug type, the order of application to hair may be appropriately changed.

Application of the hair dye to the hair can be performed according to a known method, and specific examples include a method of applying directly to the hair, a method of applying to the hair using a tool such as a hand or a brush, and the like.
The time for applying the hair dye to the hair and allowing it to stand can be set as appropriate. Moreover, what is necessary is just to use a well-known method for the method of washing away a hair dye.
What is necessary is just to set suitably as the provision amount to the hair of a hair dye composition according to the length etc. of hair.

Next, examples of the present invention will be described together with comparative examples, but the present invention is not limited to the following examples.
The hair dyes of Examples and Comparative Examples of the present invention were prepared with the compositions shown in Table 1. In addition, unless otherwise indicated, the quantity of each component in the following table | surfaces is represented by "weight%".

  Using the hair dyes of these Examples and Comparative Examples, Dyeing Test 1 was performed as follows. The measurement results are shown in Table 1. Here, the ΔL value indicates a brightness difference with respect to the reference in the table. As a result, in the hair dye added with phenylethyl alcohol, eugenol, vanillin, camphor, caffeine, cinnamon oil and clove oil, the lightness is low, and it can be seen that the dyeability is clearly improved.

[Dyeing test 1]
2.0 g of the prepared hair dyes of Examples and Comparative Examples were taken and evenly applied to an attached white cloth for dyeing fastness test (nominal number 1, 5 cm × 5 cm) according to JISL0803, and then allowed to stand at room temperature for 10 minutes. Thereafter, it was washed with a 3% sodium laureth sulfate solution and air-dried.
Lab of the dyeing | staining part of a white cloth was measured using color reader CR-13 type | mold (made by Konica Minolta), and the average value at the time of measuring 3 times as a measurement result was shown.

  Next, hair dyes of Examples and Comparative Examples of the present invention were prepared with the compositions shown in Table 2.

  Using the hair dyes of these Examples and Comparative Examples, the dyeing test 1 was performed. As a result, it can be seen that the color difference in the blue direction is enhanced and the dyeing property of the blue basic dye is improved in the hair dye of the example to which eugenol and camphor were added as compared with the standard.

  Next, hair dyes of inventive examples and comparative examples were prepared with the compositions shown in Table 3.

  Using the hair dyes of these Examples and Comparative Examples, the dyeing test 1 was performed. As a result, it can be seen that the brightness of the hair dye of the example to which eugenol was added was lower than the standard, and the dyeability was clearly improved.

  Subsequently, the hair dyes of Examples and Comparative Examples of the present invention were prepared with the compositions shown in Tables 4, 5, and 6.

  Using these one-component hair dyes in Examples and Comparative Examples, hair dye test 2 was performed as follows. As a result, in the hair dye added with eugenol and phenylethyl alcohol, the lightness is low, and it can be seen that the dyeability is clearly improved.

[Hair dyeing test 2]
After taking and mixing 5.0 g of the prepared one-component hair dye of Examples and Comparative Examples, and uniformly applying to 8 cm (0.4 g) of human white hair BM-WA (Burelux) The mixture was allowed to stand at room temperature for 30 minutes, washed with a 3% sodium laureth sulfate solution, and air-dried.
Lab of dyed white hair of human hair was measured using a color reader CR-13 type (manufactured by Konica Minolta), and the average value when measured three times was shown.

  Furthermore, the two-component hair dyes of Examples and Comparative Examples of the present invention were prepared with the compositions shown in Tables 7, 8, and 9.

A test similar to the above-mentioned hair dyeing test 2 was carried out by using 2.0 g of the first and second hair dyes of the prepared Examples and Comparative Examples.
As a result, in the hair dye added with eugenol, the lightness is low, and it can be seen that the dyeability is clearly improved even in the two-part dosage form.
