Description

Composition for the anti-irritation effect on the scalp containing natural ingredients for hair colorants}

The present invention relates to a composition for relieving scalp irritation used in combination with a conventional hair dye, and more particularly, scalp stimulation using one or two or more mixtures selected from green tea polysaccharide, polysaccharide polysaccharide, peony, lotus root and nasturtium as an active ingredient. It relates to a composition for relaxation.

Hair dyes are classified into permanent hair dyes, semi-permanent hair dyes, temporary hair dyes and other hair dyes depending on how long the dyed color lasts.

Permanent hair dye is generally referred to as "oxidative hair dye". Oxidative hair dye is a principle that shows the color by the oxidation reaction of the dye using an oxidizing dye. Oxidized permanent hair dyes consist of one type, but generally consist of one type of hair dye and a second type of oxidant. It contains an oxidizing dye precursor and a coupler as a dye for coloring, and an alkaline agent such as ammonia and monoethanolamine that swells the hair and promotes the decomposition of hydrogen peroxide to cause an oxidation reaction. In addition, a chelating agent is used for the purpose of controlling the oxidation reaction of the dye using a reducing agent or an antioxidant and blocking the metal ions. In addition, hair conditioning agents and fragrances such as patty alcohols, surfactants or cationic polymers are included. Hydrogen peroxide contained in the oxidant, the second agent, decomposes the melanin in the hair to brighten the color of the hair and promotes the oxidation reaction of the dye.

Semi-permanent hair dye is a principle of dyeing hair using acid dyes or basic dyes which are non-oxidizing dyes. These dyes do not undergo an oxidative polymerization reaction and are colored as themselves and are attached to the hair by ionic bonds with amino acids of the hair to dye the hair. It is relatively large in size compared to oxidized dyes and does not penetrate deep into the hair.

Temporary hair dye is a pigment or pearl is attached to the surface of the hair using a film forming agent to temporarily impart a coloring effect to the hair.

Other hair dyes include hair dyes using vegetable natural dyes such as henna, indigo and chamomile, metallic hair dyes which dye the hair by oxidation of silver nitrate and lead acetate.

Oxidative hair dyes generally exhibit a color by causing an oxidation polymerization reaction between dyes contained in the first agent by mixing the first agent and the second agent. In addition, the melanin pigment in the hair is decomposed by the hydrogen peroxide contained in the second agent, thereby decolorizing the hair, thereby brightening the background color of the hair, thereby providing a more vivid color.

These oxidative permanent hair dyes have an advantage of excellent color persistence because the dye penetrates into the hair and exhibits color by oxidative polymerization. However, dyes used in hair dyes may cause allergies and should only be used after a patch test before use. In addition, alkaline agents and hydrogen peroxide can cause scalp and skin irritation and damage hair proteins. Increasing the amount of alkali agent to make the color brighter will make the color brighter but also increase irritation and hair damage. In addition, if the ammonia content is increased, there is a problem that a lot of smell.

In modern society, many people, regardless of age or gender, use hair dyes to satisfy their cravings or individual expression needs. In some people, allergic reactions are caused by oxidative dyes used in oxidative hair dyes. In some cases, the whole body is swollen or the scalp is sore that it can not be dyed. In the case of sensitive scalp, the use of hair dyes can cause irritation or inflammation, such as itching and itching of the scalp.

In order to reduce such irritation, acid dyes and temporary dyes may be used instead of oxidizing dyes, but in this case, the quality of hair dyes such as dyeing power is inferior to that of permanent hair dyes. In addition, the stimulus is not completely eliminated by these dyes. Therefore, in order to reduce the scalp irritation and inflammation caused by the use of hair dyes and to reduce the side effects caused by the use of hair dyes, it is urgent to develop a composition that can reduce the irritation of hair dyes by using ingredients having anti-inflammatory and skin irritation efficacy.

In general, the stimulation that occurs in hair dyes can be divided into allergic reactions caused by dyes and stimuli caused by other raw materials such as alkali agents or hydrogen peroxide, and are generally referred to as stimuli.

Oxidative dyes widely used in oxidative permanent hair dyes include diamines such as paraphenylenediamine, paratoluenediamine, and metaphenylenediamine based on aromatic ring compounds; Aminophenols such as paraaminophenol, metaaminophenol and orthoaminophenol; Phenols such as resorcinol and other aromatic compounds and derivatives thereof. Many of these oxidative dyes are known to cause allergies, and particularly, paraphenylenediamine is known to have a severe allergy.

In addition, there may be irritation caused by scalp, skin irritation, hydrogen peroxide and other raw materials such as monoethanolamine and ammonia, which are alkali agents used to control pH, and in this case, reactions occur in the form of burning, erythema and itching. .
