Description

TECHNICAL FIELD The present invention relates to a composition for a hair dye for hair dyes, which contains a natural component as an active ingredient,

The present invention relates to a composition for alleviating scalp irritation which is used in combination with a conventional hair dye, and more particularly to a composition for alleviating scalp irritation which comprises a mixture of one or more selected from green tea polysaccharide, The present invention relates to a composition for relieving pain.

The hair dye is classified into permanent hair dye, permanent hair dye, temporary hair dye and other hair dye depending on how long the stained color lasts.

Permanent hair dye is generally called an "oxidative dye". The oxidative dyeing agent is a principle which shows color by oxidation reaction of dyes using oxidative dye. Oxidative permanent hair dye is made up of 1 formulation, but usually consists of a hair dye 1 agent and an oxidizer 2. 1 is a dye for coloring and contains an oxidizing dye precursor and a coupler and contains an alkaline agent such as ammonia and monoethanolamine which causes the oxidation reaction by promoting the decomposition of hydrogen peroxide by swelling the hair. A chelating agent is also used for the purpose of controlling the oxidation reaction of dyes using a reducing agent or an antioxidant and blocking metal ions. In addition, hair conditioning agents and fragrances such as patty alcohols, surfactants or cationic polymers are included. 2 Hydrogen peroxide in the oxidizing agent oxidizes the melanin of the hair, brightens the background color of the hair, and promotes the oxidation reaction of the dye.

The semi-permanent hair dye is a principle of dyeing hair using non-oxidative dyes such as acid dyes or basic dyes. These dyes do not oxidize and polymerize, but are themselves colored dyes that attach to the hair by ionic bonding with the amino acid of the hair and dye the hair. It is relatively large in size compared to oxidative dyes and can not penetrate deeper into the hair (to the layer of the hair).

The hair dyeing agent temporarily attaches pigment or pearl to the surface of the hair using a film forming agent, thereby temporarily imparting a coloring effect to the hair.

Other hair dyeing agents include hair dyeing agents using vegetable natural dyes such as henna, indigo and chamomile, and metallic hair dyeing agents for dyeing hair by oxidation of silver nitrate and acetic acid.

Oxidation type dyeing agents are generally colored by causing oxidation polymerization reaction between the dyes contained in one agent by mixing one agent and two agents. In addition, the hydrogen peroxide in the 2nd agent breaks down the melanin pigment in the hair to discolor the hair, so that the hue of the hair is brightened, and a brighter color can be expressed.

The oxidative permanent hair dye has the advantage of excellent color sustainability because the dye penetrates into hair and exhibits color by oxidation polymerization reaction. However, allergies may be caused by the dye used in the hair dye, so it should be used only when there is no abnormality after performing patch test before use. Alkaline and hydrogen peroxide can also cause scalp or skin irritation and damage hair proteins. Increasing the content of alkaline agent to brighten the color brightens the color but increases the irritation and hair damage. Also, when the ammonia content is increased, there is a problem that the smell is increased.

In modern society, many people, regardless of age and sex, use hair dye to satisfy the need for cover (white moth) cover or expression of individuality. In some people, oxidative dye used in oxidative dye makes an allergic reaction Or swelling of the whole body, or scalp, is often the case, there is a case that can not dye. In the case of the sensitive scalp, the use of hair dye may also cause irritation or inflammation such as itching or stinging of the scalp.

To reduce such irritation, acid dyes and temporary dyes other than oxidative dyes may be used. However, in this case, there is a drawback in that the quality of the hair dye is deteriorated compared to the permanent hair dye. Also, irritation can not be completely eliminated by these dyes. Therefore, in order to reduce the irritation and inflammation of the scalp due to the use of the hair dye, and to reduce the side effects due to the use of the hair dye, it is necessary to develop a composition capable of reducing the irritation of the hair dye using the anti-inflammatory and skin irritation-

In general, the stimuli generated in the hair dye can be divided into allergic reaction by the dye and stimulation by other raw materials such as an alkali agent or hydrogen peroxide, and are generally called stimuli in general.

Oxidative dyes that are widely used for oxidative permanent hair dyeing agents include diamines such as paraphenylenediamine, paratoluenediamine and metaphenylene diamine having an aromatic ring compound as a basic structure; Aminophenols such as paraaminophenol, metaaminophenol and orthoaminophenol; Phenols such as resorcinol and other aromatic compounds and their derivatives. Many of these oxidative dyes are known to induce allergies, and paraphenylenediamine is known to be highly allergenic.

In addition, there may be stimulation by the scalp, skin irritation, hydrogen peroxide and other raw materials caused by monoethanolamine and ammonia which are used for adjusting the pH, and in this case, reactions occur in the form of burning, erythema and itching .

As a technique attempted to reduce such skin irritation, Korean Unexamined Patent Application Publication No. 2003-15654 discloses a composition for external application for skin containing raspberry leaves or fruit extract having skin irritation and inflammation alleviating effect, 2006-70847 discloses a composition for external application for relieving scalp irritation containing raspberry leaves or fruit extract.

 [Examples 1 to 12 and Comparative Example 1]

[Test Example 1] Confirmation of stimulation relaxation effect through panel test

In order to confirm the irritation mitigation effect of the present invention, the test was conducted on a panel which had difficulty in dyeing due to irritation to the usual hair dye.

Four subjects were divided into four groups of 48 subjects in each of the groups A, B, C, D, E, F, G, H, I, J, K, and L. Dividing the above- .

Group A: The mixture of Example 1 and oxidant was mixed with Example 3

Group B: When Example 1 and oxidizer were mixed, Example 4 was mixed
