Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(1) Next, modes for carrying out the invention will be described, including the best mode. The technical scope of the invention is not limited by the following embodiments.

(2) [Powder Hair Dye Composition]

(3) The powder hair dye composition of the invention is a composition in powder form for subjecting the hair to a hair-dyeing treatment, and examples thereof include oxidation hair dye compositions in powder form. The powder hair dye composition contains: as an oxidizing agent, sodium percarbonate (component (A)) incorporated in such an amount that the content thereof is 1.8 to 3.7 mass % at the time of use; p-phenylenediamine sulfate (component (B)) as a key intermediate of an oxidation dye; and m-aminophenol sulfate (component (C)) as a coupler of an oxidation dye. Usually, an alkaline agent is also contained, and a direct dye is also occasionally incorporated.

(4) When the powder hair dye composition of the invention is used, similarly to ordinary powder hair dyes, the powder hair dye composition is dissolved in a suitable dissolving liquid such as water to prepare a chemical liquid in paste form, then applied to the hair using a comb, a brush, or the like, and left on for 30 minutes to 40 minutes, thereby dyeing the hair.

(5) A certain mixing ratio between powder hair dye and dissolving liquid at the time of using the powder hair dye is previously set, and the amount of each component to be incorporated in the powder hair dye composition is determined considering such a mixing ratio. For example, the amount of component (A) incorporated described above also has to be determined by calculation considering this mixing ratio. The mixing ratio between powder hair dye and dissolving liquid in the powder hair dye composition of the invention can be set, for example, as a mass ratio within a range of about 1:1 to 1:20, more preferably about 1:2 to 1:10.

(6) [Initial 1% pH]

(7) As described above, sodium percarbonate in powder form mixed with water produces sodium carbonate, which is a weak alkali. In this relation, it has been found that under the condition where alkaline agents other than sodium percarbonate are not contained, initial 1% pH at the time of using the hair dye can be effectively used as a novel, practical, simple index to predict/determine whether the hair dye of the invention will exceed pH 9 during a leave-on time of 30 minutes to 40 minutes. Initial 1% pH refers to the pH of a diluent prepared by dissolving the powder hair dye composition in a dissolving liquid such as water in a ratio to be employed at the time of use, immediately followed by 100-fold dilution with water.

(8) Therefore, in the case where a powder hair dye composition that is designed to dye the hair to a sharp black hue and meets the above conditions is prepared, without actually using it on the hair for trial, or performing a hair-dyeing test using a hair tuft sample, when the initial 1% pH at the time of using the hair dye is 8.0 or less, particularly preferably 7.5 or less, it can be preparatorily confirmed that the hair dye is a hair dye that does not exceed pH 9 during a leave-on time of 30 minutes to 40 minutes at the time of use and does not give a reddish hue to the dyed hair.

(9) [Main Components in Powder Hair Dye Composition]

(10) (Component (A))

(11) Component (A) is sodium percarbonate. From the reasons described in Advantageous Effects of Invention above, the amount of component (A) incorporated in the powder hair dye composition is (considering the mixing ratio between powder hair dye and dissolving liquid) such that the content thereof is 1.8 to 3.7 mass % at the time of use, more preferably such that the content thereof is 1.8 to 3.2 mass % at the time of use.

(12) (Component (B) and Component (C))

(13) Component (B) is p-phenylenediamine sulfate which is a key intermediate of an oxidation dye, while component (C) is m-aminophenol sulfate which is a coupler of an oxidation dye. The amounts of component (B) and component (C) incorporated in the powder hair dye composition are not limited, but it is preferable that the amount of component (B) is at least 7.5 times, more preferably at least 10 times, the amount of component (C) on mass basis. In addition, the amount of p-phenylenediamine sulfate incorporated in the powder hair dye composition is preferably such that the content thereof is 0.4 to 3.7 mass %, more preferably 0.9 to 2.8 mass %, at the time of use, and the amount of m-aminophenol sulfate incorporated in the powder hair dye composition is preferably such that the content thereof is 0.009 to 1.0 mass %, more preferably 0.09 to 0.5 mass %, at the time of use.

(14) (Alkaline Agent)

(15) In the powder hair dye composition of the invention, an alkaline agent is usually incorporated for the purpose of improving the dyeability. The powder hair dye composition of the invention contains sodium percarbonate as an essential component. When mixed with a liquid media such as water, powder sodium percarbonate is decomposed to produce sodium carbonate, which is an alkaline agent.

(57) [Preparation of Powder Hair Dye Composition]

(58) Powder hair dye compositions of Example 1 to Example 8 and Comparative Example 1 to Comparative Example 3 shown in Table 1 and Table 2, respectively, at the end were prepared. The components of the powder hair dye composition of each case are all in powder form. In addition, 3 g of the powder hair dye composition of each case is to be dissolved in 30 ml of water before use. That is, in all the examples and comparative examples, the mixing ratio between powder hair dye and dissolving liquid (water) at the time of use is substantially 1:10.

(59) In Table 1 and Table 2, of the components, those corresponding to the components (A) to (C) of the invention are indicated with symbols A to C, respectively, in the left-hand margin of each table.

(60) In each case shown in Table 1 and Table 2, the value showing the content of each component is mass % in the powder hair dye composition. Therefore, the content of each component at the time of use can be calculated including the above mixing ratio. The content of component (A) specified in the first invention, that is, 1.8 to 3.7 mass % at the time of use, is equivalent to 19.8 to 40.7 mass % in the powder hair dye composition.

(61) Further, after the preparation of the powder hair dye composition of each case, the composition was partially dissolved in water in accordance with the above mixing ratio and then immediately diluted 100-fold with water, and the pH of the diluent was measured. The initial 1% pH at the time of use of the powder hair dye composition of each of the examples and comparative examples thus measured is shown in the corresponding column of each table. In addition, the mass ratio of the content of component (B) to the content of component (C) in the powder hair dye composition of each case is shown in the B/C column of each table.

(62) [Evaluation of Powder Hair Dye Composition]

(63) With respect to the powder hair dye composition of each of the examples and comparative examples, a 10-g sample immediately after preparation was mixed with 100 ml of water and dissolved, then uniformly applied to a test white hair tuft, and left on for 30 minutes to perform a hair-dyeing treatment. After the completion of the hair-dyeing treatment, ten panelists visually observed the hair tuft to evaluate the hair-dyeing power of each hair dye and the redness of the hue of the dyed hair.

(64) (Evaluation of Hair-Dyeing Power of Hair Dye)

(65) The hair-dyeing power was evaluated based on whether the hair-dyeing power was good or not good. In the case where eight or more out of ten panelists chose good, rank 5 was given. In the case where six or seven chose good, rank 4 was given. In the case where four or five chose good, rank 3 was given. In the case where two or three chose good, rank 2 was given. In the case where one or zero chose good, rank 1 was given. The evaluation results are shown in the Hair-dyeing power column of each table.

(66) (Evaluation of Redness of Hue of Dyed Hair)

(67) The redness of the hue of the dyed hair was evaluated based on whether the hair had clear black hue without redness (positive evaluation) or black hue with perceptible redness (negative evaluation). In the case where eight or more out of ten panelists chose the positive evaluation, rank 5 was given. In the case where six or seven chose the positive evaluation, rank 4 was given. In the case where four or five chose the positive evaluation, rank 3 was given. In the case where two or three chose the positive evaluation, rank 2 was given. In the case where one or zero chose the positive evaluation, rank 1 was given. The evaluation results are shown in the Redness column of each table.
