Description

Composition for oxidative dyeing of hair

The present invention relates to an oxidative hair dye composition capable of changing the color of hair, and more particularly, by containing an extract extracted from a plant food containing a large amount of anthocyanin pigment in a hair dye using an oxidative dye. The polymer of the oxidative dye, which penetrates into the cortex of the hair and is colored by the condensation reaction with the oxidizing agent, can escape the hair and block the cause of the faded color so that the color of the dyed hair is maintained for a long time. The present invention relates to an oxidative hair dye composition which maintains a smooth state of hair even after dyeing by maintaining a moisturizing effect of the hair and preventing hair from becoming rough.

In general, hair dyeing is performed to restore aging gray hair to its original color, to change the original hair color to a more attractive color tone or contrast, or to restore the original natural color after dyeing. do.

The history of human hair dye is known from ancient Egypt a long time ago. At that time, oil extracted from animal blood, horns and body was used as a dye, followed by dyeing with natural products such as henna, antimony, and lead.

The beginning of modern dyeing was the discovery of paraphenylene diamine in 1863 and the use of it as a hair dye in 1883.

Hair dyeing can be broadly classified into three types: temporary dyeing, semi-permanent dyeing, and permanent dyeing. This classification is primarily based on the degree of fastness of the dye to the hair.

Permanent hair dyes that allow permanent dyeing in the above classification, also called oxidative hair dyes, are designed to allow pigments to penetrate the cuticle and precipitate pigment molecules in the cortex. Due to the infiltration and the addition of oxidants, these hair dyes also cause coloration and coloration.

The dyes used for permanent dyeing are divided into vegetable dyes, metallic dyes, mixed dyes, and oxidative dyes (organic dyes).

The most commonly used oxidizing dye is the present invention also uses an oxidizing dye.

These dyes are known to be basic in nature, soluble in water and alcohol, readily oxidized, and resistant to air when in keratin in hair. In 1888, Germany's E. Ertmann released an aminophenol-based hair dye and has made remarkable progress.

These oxidative dyes have been continuously developed since their inception and can now produce more than 60,000 shades. These oxidation tints are also known as dyes derived from aniline, synthetic organic dyes, and aminotints.

Generally, oxidative hair dyes are composed of one agent and two agents. The first agent contains a dye and an alkali agent, and the alkali agent is an ingredient that inflates the hair shaft and helps small dyes settle in the cortex through the cuticle of the hair shaft portion, and ammonia and monoethanolamine are mainly used. The two agents are called oxidizing agents and mainly contain hydrogen peroxide.

When the first agent and the second agent are mixed, the dye starts to react with the oxygen molecules produced by hydrogen peroxide, and the color appears on the hair by the condensation reaction of the dyes. In addition, dye polymers having a high molecular weight due to a bonding reaction with each other are changed into insoluble solids over time, so that they cannot escape between narrow cuticles, and thus remain inside the cortex, which is a property of hair dyes using oxidative dyes. This is why it is called permanent hair dye.

In the case of dyeing the hair using such an oxidative hair dye, in theory, the dyed color should be kept as long as it does not cut the hair, but this is not the case. The main reason why the color of this dyed hair is not permanently maintained is the ultraviolet rays of sunlight.

Ultraviolet light penetrates into the hair and oxidizes the dye polymer, which turns into an insoluble solid, breaking the bond, returning it to its initial small molecular weight state, and the smaller polymer is discharged out of the hair through the cuticle and eventually dyed to the hair. The faded color will cause fading.

On the other hand, alkalis are used to induce dye swelling to facilitate the penetration of dyes, and if such hair swelling occurs repeatedly, damage to the cuticle and cortex occurs. In addition, since the surfactant component contained in the hair dye composition removes a lipid layer of the cuticle, hair after hair dye has a problem inevitably losing its glossiness and becoming rough.

In order to solve this problem,

oxidizing dyes containing any one of m-Aminophenol, Resorcine, p-Phenylenediamine and p-Aminophenol, chelating agent, antioxidant, emulsifier, thickener, solubilizer, preservative, solvent, flavoring agent, Any of the following: In a hair dye composition comprising a hair protectant and an oxidizing agent, there has been provided a hair dye composition comprising a cephalopod ink extract. (Patent application 2006-77500)

However, the conventional hair dye composition as described above has some effects on hair damage and skin sensitization to the scalp due to dyeing, but does not prevent the dye polymer from being oxidized by ultraviolet rays.

The present invention contains an extract extracted from a vegetable food containing a large amount of anthocyanin pigments in a hair dye using an oxidizing dye, thereby penetrating into the cortex of the hair and coloring by condensation with an oxidizing agent. The polymer of the dye is released from the hair to block the cause of the faded color to maintain the color of the dyed hair for a long time, to maintain the moisturizing effect of the hair to suppress the roughness of the hair, even after dyeing the hair It is an object of the present invention to provide an oxidative hair dye composition which enables to maintain a smooth state of.

In the present invention, the cephalopod ink extract is included in an oxidative hair dye using an oxidative dye (Oxidation tints),

Fatty acid or fatty alcohol 2.0-25.0 wt%; 0.5-20.0 wt% surfactant; 0.01 ~ 10.0% by weight of a mixed extract extracted from black beans and black sesame, which are vegetable grains containing anthocyanin pigments; 0.1-10.0 wt% of an oxidative dye; 1 agent comprising 0.1 to 20.0 wt% of alkaline agent and 15.0 to 97.29 wt% of purified water;

It is characterized by including a two agent containing an oxidizing agent for hair dye.

The present invention as described above penetrates into the cortex of the hair, and the polymer of the oxidative dye, which is colored by the condensation reaction with the oxidizing agent, is blocked from the hair and causes the dyed color to fade. The color is maintained for a long time, the moisturizing effect of the hair lasts to prevent the roughness of the hair, there is an effect that can maintain the smooth state of the hair even after dyeing.

The present invention provides an oxidative hair dye composition containing a mixed extract of black beans and black sesame as an active ingredient.

The inventors of the present invention performed a screening process for selecting natural substances that are safe when hair dyes are prepared because of excellent persistence of dyeing and little skin irritation. One has found the best fit for the purpose of the present invention.

The black bean and black sesame mixed extract of the present invention may be prepared according to conventional methods known in the art, that is, using a conventional solvent under conditions of conventional temperature and pressure.

As an extraction solvent for preparing the black soybean and black sesame complex extracts, the active ingredients of the oxidizing hair dye of the present invention, a solvent generally used in cosmetics may be used. It is preferably extracted using a solvent selected from the group consisting of alcohol, acetone, ethyl acetate, butyl acetate and 1,3-butylene glycol, more preferably ethyl alcohol, even more preferably 5% to 20 % Ethyl alcohol.
