Embodiment 1～9 and comparative example 1～2

[0160] The oxidative hair decoloring agents shown in Table 2 were prepared according to a conventional method.

[0161]

[0162] After mixing 1.5 parts by weight of the second part with 1 part by weight of the first part, apply to Japanese black hair (a small amount of 1 gram) at 30°C, and wash it with a normal shampoo after 30 minutes of action time. Shampoo and dry. The color tone of the obtained decolorized hair was measured using a color difference meter manufactured by Minolta Corporation, and the color tone change from untreated hair was determined. As a result, the decolorization property of any hair in Examples 1-9 was favorable compared with the comparative example 1, and it was equivalent to the comparative example 2. On the other hand, in terms of hair touch, the decolorized hair of Comparative Example 2 felt relatively strong damage, while any of the hair in Examples 1 to 9 felt only weak damage to the extent of Comparative Example 1.

Embodiment 10～14 and comparative example 3～4

[0164] The oxidative hair decoloring agents shown in Table 3 were prepared according to a conventional method.

[0165]

[0166] In the same manner as in Examples 1 to 9, decolorization, washing and drying were carried out, and the color tone of the obtained decolorized hair was measured, and the change in color tone from untreated hair was determined. As a result, the decolorization property of any hair in Examples 10-14 was favorable compared with the comparative example 3, and it was equivalent to the comparative example 4. On the other hand, in terms of hair touch, the decolorized hair of Comparative Example 4 felt relatively strong damage, while any of the hair in Examples 10 to 14 felt only weak damage of the level of Comparative Example 3.

Embodiment 15～24

[0168] The oxidative hair decoloring agents shown in Table 4 and Table 5 were prepared according to a conventional method.

[0169] Table 4

[0170]

[0171] a): Amount to make the pH value reach 9.8 b): Amount to make the pH value reach 3.5

[0172] table 5

[0173]

[0174] a): Amount to make the pH value reach 9.8 b): Amount to make the pH value reach 3.5

[0175] Except for using 1 part by weight of the second component to 1 part by weight of the first component, the others are the same as in Examples 1 to 9, decolorized, washed and dried, and measure the hue of the decolorized hair obtained, and obtain the color tone of the obtained decolorized hair, and obtain the difference with that of the untreated hair. of color changes. As a result, the decolorization of any hair in Examples 20 to 24 was significantly higher than that of any of the compounds (1-2), (1-3), (1-4), and (2-1) without addition. it is good.

Abstract

A two-component hair bleach composition which comprises (a) a nitrogen-containing compound represented by the general formula (1) or (2) or a salt thereof or (A) a nitrogen-containing compound which exhibits an octanol / water partition coefficient (P) whose common logarithm (lop10P) is -1 to 4 and a residue of hydrogen peroxide of 5 to 90 %, or a salt thereof, (b) an oxidizing agent, and, if necessary, (c) an alkali agent and which exhibits a pH of 7.5 to 12 after mixing; a two-component hair dye composition which further contains (d) an oxidation dye or a direct dye in addition to the above components; and an additive for hair treatment, consisting of the component (a) or (A).

Description

technical field [0001] The present invention relates to a hair decolorizing agent composition and a hair dye composition having less hair damage during and after the operation, less irritation to the skin, and high hair decolorizing ability and dyeing power, and an additive for the use. Background technique [0002] In the decolorization and dyeing of hair, two-component decolorizers and long-lasting hair dyes formed of a first component containing an alkaline agent and a second component containing an oxidizing agent are widely used. The oxidizing agent of the second component is used to improve the hair dyeing effect brought by the coupling reaction of the oxidation dye intermediate, and at the same time, the melanin particles in the hair are oxidized and decomposed, so that the hair shows a bright color. The first component of the alkaline agent is used to make the oxidizing agent more active and improve the hair dyeing effect and decolorization effect. When decoloring t...
