Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a second permanent agent for simultaneously shaping with a permanent and coloring with an acidic dye, and more particularly to a second permanent agent having high hair dyeability.

[0002]

2. Description of the Related Art Perm agents are used to semi-permanently shape hair such as curls and waves.
Used by people of all ages. On the other hand, as for hair dyes, not only can the elderly dye black to hide gray hair, but young people with black hair also enjoy a variety of hair colors, including brightening the hair color and adding colors such as red and orange. It is also being used for purposes. As a type of hair dye, a permanent hair dye based on an oxidation dye is widely used, but recently, a hair manicure based on an acidic dye having high safety and a wide variety of colors is also often used.

[0003] However, when performing both a permanent and a hair manicure, it generally takes a very long time to perform a perm first and then a hair manicure. There is a problem that the rate is lowered and the subject suffers.

Therefore, various attempts have been made to use an acidic dye in a perm system in order to shorten the treatment time by simultaneously performing a permanent and a hair manicure. For example, GB7218
No. 31 discloses the addition of a water-soluble acid dye to a first permanent agent containing a mercapto compound. However, since the acid dye has a property of dyeing well under acidic conditions, particularly, a pH of less than 4 due to its electric charge, the compounding with the first permanent agent which is usually used in alkaline was not sufficient in terms of hair dyeability. Attempts have also been made to add an acid dye to the second permanent agent containing an oxidizing agent. For example, JP-A-9-151121 discloses a straight permanent second agent containing an acidic dye and preferably having a pH of 4 to 8. Is disclosed. However, sufficient hair dyeing properties could not be obtained by the method disclosed in the publication.

[0005]

Accordingly, an object of the present invention is to provide a second permanent agent which exhibits high hair dyeing properties in a simple operation for simultaneously shaping the hair with a perm and coloring with a hair manicure. Aim.

EXAMPLES Test Example 1 Relationship between pH of Second Agent and Hair Dyeing Property First permanent agent (pH = 8.5) shown below and second hair of various pH
Agents (pH = 2.5, 3.0, 3.5, 4.0 and 4.5; Formulations A to E) were prepared, and their hair dyeability was evaluated.

(Test Method) Using 1 g of a natural white-colored hair bundle of a Westerner, a first ratio of perm was applied to a bath ratio (hair: liquid).
1: 2 was applied. After leaving at room temperature (about 25 ° C) for 15 minutes,
After rinsing with running water and drying with a towel, the second permanent agent was applied at a bath ratio of 1: 2. After standing at room temperature (about 25 ° C.) for 15 minutes, it was rinsed with running water, washed twice with a commercial shampoo, and treated with a commercial rinse. After the towel was dried, it was dried with a dryer. The hair bundle before and after this treatment was measured using a color difference meter CR-200 manufactured by Minolta Camera Co., Ltd., and the ΔE value was determined. In the case of Red No. 106 used in this test, if ΔE> 80, the dyeing is very strong. Even if ΔE> 70, it can be said that the dyeing is sufficient. However, if ΔE ≦ 70, the dyeing is insufficient.
