Embodiment 1～9 and comparative example 1～2

[0162] According to a conventional method, the oxidized hair bleaching agents shown in Table 2 were prepared.

[0163] Example

[0164] After mixing 1.5 parts by weight of the second component to 1 part by weight of the first component, it is suitable for Japanese black hair (1g trace amount) at 30℃, after 30 minutes of action time, wash it with a normal shampoo Hair is cleaned and dried. 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 that of untreated hair was determined. As a result, the bleaching property of any hair in Examples 1-9 was very good compared with Comparative Example 1, and was comparable to Comparative Example 2. In terms of hair touch, the decolorized hair of Comparative Example 2 felt strong damage, while any of the hairs of Examples 1 to 9 only felt weak damage to the extent of Comparative Example 1.

Embodiment 10～14 and comparative example 3～4

[0166] Example

[0167] In the same manner as in Examples 1-9, bleaching, washing and drying were carried out, the hue of the resulting bleached hair was measured, and the hue change from untreated hair was determined. As a result, the bleaching property of any hair in Examples 10-14 was very good compared with Comparative Example 3, and was equivalent to Comparative Example 4. In terms of hair touch, the depigmented hair of Comparative Example 4 felt strong damage, while the hair of any of Examples 10 to 14 only felt weak damage to the extent of Comparative Example 3.

Embodiment 15～24

[0169] The oxidized hair bleaching agents shown in Table 4 and Table 5 were prepared according to a conventional method.

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 bleaching agent composition and a hair dye composition that have less hair damage during and after surgery, less irritation to the skin, hair bleaching ability, and strong dyeing power, and additives for the use. Background technique [0002] In the bleaching and dyeing of hair, two-component bleaching agents and long-lasting hair dyes formed by the first component containing an alkaline agent and the second component containing an oxidizing agent are widely used. The added oxidant of the second component is used to improve the hair dyeing effect brought about by the coupling reaction of the oxidative dye intermediate, and at the same time to oxidize and decompose the melanin particles in the hair to make the hair show bright color. The mixed alkaline agent of the first component is used to make the oxidant more active, and improve the hair dyeing effect and decolorizing effect. When the hair is decolorized to form a ...
