Description

OXIDATIVE HAIR DYE COMPOSITION [0002]

The present invention relates to an oxidation dye composition comprising a carbonate as an alkaline agent.

BACKGROUND ART [0002] In general, a hair dye composition which exhibits an effect by mixing a plurality of medicines is known. As such a hair dye composition, there is known a hair dye composition comprising a first agent containing, for example, an alkali agent and an oxidation dye, and a second agent containing an oxidizing agent such as hydrogen peroxide. The alkaline agent promotes the action of the oxidizing agent contained in the second agent and at the same time swells the hair to improve the permeability of the dye into the hair, thereby improving the salt strength. BACKGROUND ART [0002] Ammonia and the like are conventionally known as an alkali used in an oxidation dyeing composition. However, there is a problem that ammonia accompanies an irritating odor if the amount of ammonia is increased.

BACKGROUND ART [0002] Conventionally, for example, the oxide hair dye composition disclosed in the following patent documents 1 to 3 is known. Patent Documents 1 to 3 use ammonia and carbonate as alkaline agents in combination to lower the compounding amount of ammonia and to improve the salt strength.

Color saturation was evaluated in terms of saturation and color intensity. (5 points), good (4 points), feasible (3 points), somewhat defective (2 points), and poor (5 points) were observed by visually observing the color of the human hair after 10 groups of the panel treated with the oxidative dye composition, (1 point). The average value of the evaluation results of each panel was calculated as follows: 'Excellent: 5' for the average score of 4.6 or more, 'Good' for less than 4.6 points, 'Possible: 3' for less than 2.6 points, 1.6 points or more and less than 2.6 points were evaluated as "somewhat defective: 2" and less than 1.6 points were defined as "defective: 1". The results are shown in Tables 1A to 1D.

[Table 2]

As shown in Tables 1A to 1D, it was found that the evaluation of irritation, lightness and color for each of the Comparative Examples in the oxidation hair dye composition according to each Example was high. In addition, from the results of Examples 1 to 4, there was no difference in the effect due to the difference in the carbon number of the sugar alcohol and the difference in isomers. Mannitol is an isomer of sorbitol.

As shown in Table 1, in Comparative Example 1 in which (C) sugar alcohol was not contained, it was found that the evaluation of color feeling was low in each example. It was found that the evaluation of irritancy and lightness for each Example was low in Comparative Example 2 in which (A) carbonate was not contained. In Comparative Example 3 containing 1,2-butanediol as a polyhydric alcohol instead of (C) sugar alcohol of Example 1, Comparative Example 4 containing glucose as a monosaccharide and Comparative Example 5 containing glycerin having 3 carbon atoms, It was found that the evaluation of the color of the Example was low.

When the first agent of Comparative Example 1 and the second agent of Example 1 were combined and applied in combination with 1 mass% of xylitol as a sugar alcohol, Results were obtained.

Further, it is possible to prepare an oxidation dyeing composition containing ammonia as an alkali agent in an amount of 5 to 60 mass% with respect to the total alkali agent. In this case, the brightness after the hair treatment can be further improved.
