Description

Hair dye composition

The present invention relates to an oxidative hair dye composition, and more particularly, by mixing a specific nonionic surfactant and anionic surfactant to facilitate the penetration of the dye into the hair, thereby improving the dyeing property and the appropriate level of viscosity to the hair. By adding a quaternary ammonium-substituted ginseng saponin quaternary (hereinafter referred to as HGSQ) together with a cationically water-soluble high molecular compound having excellent affinity to hair, and improving color fastness. The invention relates to a hair dye composition which minimizes damage to hair.

Generally, hair dyes are classified into permanent hair dyes, semipermanent hair dyes, and temporary hair dyes according to the durability of the colored color. The composition of the present invention is composed of a first agent containing an oxidizing dye and a second agent containing an oxidizing agent. To a permanent two-part hair dye.

In the case of such a hair dye, colorless low molecular oxidizing dye penetrates the hair and causes oxidative polymerization in the hair, thereby forming a pigment. As a result, dyeing occurs, various colors can be obtained, and the hair dye has excellent characteristics. This has become a general purpose.

Such permanent hair dyes are typically used by mixing an alkali dye with an oxidizing dye, a direct dye, etc. in a first agent, and hydrogen peroxide in a second agent, and mixing the first agent and the second agent with a predetermined ratio just before use. I use it. The alkaline component of the first agent swells the hair so that the dye can easily diffuse and penetrate into the hair, and when mixed with the second agent, aids in the generation of the oxygen necessary to decompose hydrogen peroxide to oxidize the dye, which is desirable for hair dyeing. Let this be done. These oxidative hair dyes are relatively excellent in hair dyeing power, but the dyeing power is slow depending on the hair, and the color fastness of the hair is degraded due to gradual fading or discoloration due to sunlight, shampoo, and sweat. In addition, since dyeing is performed by oxidation polymerization inside the hair, the gloss and gloss may be lost, and the hair may be severely damaged, resulting in an unnatural color and poor texture.

In this regard, Japanese Patent Laid-Open No. 1-275519 discloses a hair dye composition containing a cationic denatured protein in order to improve dyeing and fastness. However, since the cationic denatured protein does not have a high molecular weight, the adsorption power to the hair is not satisfactory, and thus a considerable amount is removed by washing after hair dyeing, so that it is difficult to provide a continuous conditioning effect and improvement of dyeing and fastness.

The present inventors have studied diligently to solve the above problems, to improve the dyeing and fastness, to provide a hair dye composition that can protect the hair from the violent action of the alkali and oxidizing agent and impart a more continuous conditioning effect, When a specific nonionic surfactant and anionic surfactant are used in combination, the dye can be easily penetrated into the hair to improve dyeing property, and the hair color can be improved by giving an appropriate level of viscosity. It can provide natural color to hair more continuously, and contain quaternary ammonium-substituted ginseng saponin ether derivative (HGSQ) together with a cationic water-soluble high molecular compound having excellent affinity for hair, thereby minimizing hair damage and More conditioning effects such as overall gloss and flexibility The present invention has been made in view of the fact that the present invention can be given in an appropriate manner.

Accordingly, it is an object of the present invention to provide a hair dye composition which is excellent in dyeing property, excellent in color fastness and minimizes hair damage.

In order to achieve the above object, the hair dye composition according to the present invention is a compound of the following general formula (I), (II) or (III) based on the dyeable amount of the oxidizing dye and the oxidizing agent, the total amount of the composition 0.5-50% by weight of at least one selected nonionic surfactant, 0.1-10% by weight of anionic surfactant, 0.02-5% by weight of cationic water soluble high molecular compound and 0.01-5% by weight of quaternary ammonium substituted ginseng saponin ether derivative Characterized in that.

(Wherein n is an integer of 2 to 50)

(R is an alkyl group derived from palm oil,

x + y is an integer from 2 to 20)

(Wherein n is an integer of 1 to 40)

Hereinafter, the hair dye composition according to the present invention will be described in more detail.

Although the hair dye which is the subject of the present invention is not particularly limited, the two-component hair dye comprising the oxidizing dye and the oxidizing agent is the main subject, and the formulation of the hair dye is that the first agent and the second agent are creams, and the first agent Is a cream and the second agent is a liquid type of transparent or opaque, the first agent and the second agent is a liquid shampoo type can be applied.

Certain nonionic and anionic surfactants used in the present invention facilitate the penetration of dyes into the hair to enhance dyeing and enhance the color fastness of the expressed color by imparting proper viscosity to the hair. This can give your hair a more consistent natural look. The nonionic surfactant used for this purpose is used in an amount of 0.5 to 50% by weight, preferably 1 to 35% by weight, based on the total amount of the composition. In addition, as the anionic surfactant, one or two or more selected from sodium lauryl sulfate, ammonium lauryl sulfate, sodium laured sulfate, ammonium laured sulfate, triethanolamine lauryl sulfate, and sodium xylene sulfonate may be mixed and used. It is used in an amount of 0.1 to 10% by weight, preferably 0.3 to 5% by weight based on the total amount of the composition. More preferably, it is good to mix | blend a nonionic surfactant and an anionic surfactant in the range of 1-20: 1 by weight ratio.

In addition, the present invention uses a quaternary ammonium-substituted ginseng saponin ether derivative together with a cationized water-soluble high molecular compound for the purpose of protecting the hair from the violent action of the alkali and oxidizing agents and providing the conditioning effect more continuously. When the cationic water-soluble high molecular compound is excellent in the adsorption force to the damaged end of the cuticle layer, which is the outermost layer of the hair, the adsorption power to the hair root portion of the hair where the polypeptide chain is strongly bound in the hair is slightly decreased. It is not possible to provide the hair's protective and conditioning effects to the hair as a whole. Therefore, in the present invention, by mixing a quaternary ammonium-substituted ginseng saponin ether derivative (Domestic Patent No. 448432), which is a patented material showing excellent adsorption power to the hair root side of the hair, the entire hair conditioner such as glossiness, flexibility, etc. It can be provided uniformly.

The cationic water-soluble high molecular compound used in the present invention is polyquaternium-4, polyquaternium-7, polyquaternium-10, polyquaternium-16, polyquaternium-22, polyquaternium-24 and polyquater One or two or more selected from nium-28 may be mixed and used in an amount of 0.002 to 5% by weight, preferably 0.05 to 2% by weight, based on the total amount of the composition. In addition, the quaternary ammonium substituted ginseng saponin ether derivative is used in an amount of 0.01 to 5% by weight, preferably 0.02 to 2% by weight.
