Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment agent containing a nettle powder or a nettle extract.

[0002]

2. Description of the Related Art Conventionally, as a hair dye, a two-pack type oxidative hair dye comprising a first agent containing an oxidative dye intermediate and a second agent containing an oxidant has been widely used. This hair dye is one in which a colorless low molecular weight oxidative dye intermediate is permeated into the hair and oxidative polymerization is carried out in the hair to produce a dye, thereby dyeing the hair. In addition, as a permanent wave agent, the first liquid containing mercapto compounds such as thioglycolic acid, cysteine or salts thereof as a main component and an oxidizing agent such as potassium bromate, sodium bromate or hydrogen peroxide as a main component The second liquid is used.

[0003]

However, the above-mentioned hair dye and permanent wave preparation have a strong stimulative effect on the scalp, and therefore cause irritation, pain or inflammation of the scalp. This stimulant is said to be due to an alkaline agent, a surfactant and an oxidizing agent in the case of a hair dye, and a reducing agent, an alkaline agent and a surfactant in the case of a permanent wave agent. In addition, hair treatment agents such as shampoo, hair rinse, and hair treatment may cause inflammation of the scalp due to the surfactant contained therein.

Therefore, various proposals have been made in order to improve the above-mentioned drawbacks of these hair treatment agents, but none have been found yet.

[0005]

In view of the above situation, the present inventor has made diligent studies for the purpose of preventing scalp irritation, pain, inflammation, etc., and as a result, the present invention has been accomplished by incorporating nettle powder or nettle extract. The inventors have found that the above object is achieved, and have completed the present invention.

The structure of the present invention will be described in detail below.

The nettle extract used in the present invention is U
rtica dioica or Urtica hu
nbergiana above-ground part or roots were extracted with water, ethanol, 1,3-butylene glycol or a mixture thereof, or a water-soluble nettle extract, or U. di
oica or U. It is an oil-soluble nettle extract obtained by extracting the aerial part or roots of Thunbergiana with ether, safflower oil, sunflower oil, hexane, persic oil, liquid paraffin, soybean oil, wheat germ oil or a mixture thereof. In addition, the nettle powder is U.S. dioi
ca or U. It is obtained by crushing the above-ground part or roots of Thunbergiana into powder. The blending amount is
It is 0.005 to 10% by weight, preferably 0.01 to 5% by weight. If it is less than 0.005% by weight, sufficient irritation reduction and anti-inflammatory effects cannot be obtained, which is not preferable.

By adding the following ingredients to the hair treatment composition of the present invention, the effect of further preventing irritation, pain or inflammation of the scalp can be obtained. That is,

Second agent Hydrogen peroxide 6.0 Make up to 100% with purified water. The hair dye of the present invention having the above composition was prepared, and the first agent and the second agent were mixed in a ratio of 1: 1 and the mixture was applied to half the hair of the panel at room temperature. As a comparative example 1, the same hair dye except nettle extract was applied to the other half of the hair of the panel under the same conditions. Then, after applying both hair dyes, the hair was left for 20 minutes, and then the hair of each panelist was thoroughly rinsed with warm water of 40 ° C. and then dried.
