Oxidative Hair Dye Composition [0002]

The present invention relates to an oxidative dye hair composition. Specifically, the present invention relates to an oxidative dyeing composition which is easy to apply to hair, has a high dyeing speed, is excellent in color persistence, and can effectively remove a dye solution.

Recently, as the level of living has improved, interest in beauty has been increasing, among which beauty of hair is also an important part. In particular, hair dyeing is popularized in both modern and young people regardless of sex.

Among the hair dyeing agents for dyeing hair, the oxidative dyeing composition usually contains at least one oxidative dye precursor and at least one coupler, and is mixed with an oxidizing agent such as a hydrogen peroxide solution or the like immediately before application to the hair to perform dyeing. The purpose of using these hair dye agents is to completely dye the hair as long as possible and to maintain the hair hair effect as long as possible.

However, since conventional hair dyeing agents must be applied while brushing hair using a comb or other hairdressing tools, it is not only difficult to dye by itself, but also because uneven dyeing may occur due to a mistake of the operator during application, There are many problems.

Further, there is a problem in that it is not easy to use since the time for applying the mixed dyeing solution and the time for leaving for dyeing are long.

In addition, conventional hair dyeing agents are irritating to the scalp, so repeated use of hair dyeing agents can cause great problems for the user. In addition, since the dyeing solution remaining on the scalp and the skin is not easily removed during dyeing, the use of the dyeing solution is very inconvenient.

Accordingly, a problem to be solved by the present invention is to provide a dyestuff solution which is easily applied to hair, has a fast dyeing speed and excellent color sustainability as well as hair and scalp damage, and remains on hair, scalp and skin It is an object of the present invention to provide an oxidative hair dye composition which can effectively remove contaminants.

In order to solve the above problems, an oxidative dyeing composition of the present invention is characterized by comprising an oxidative dye precursor and an oxidative dyeing composition containing a coupler, wherein the oxidizing dyeing composition comprises a nonionic surfactant having an HLB value of 12.0 or less and an alkanolamide.

The nonionic surfactant according to the present invention is selected from the group consisting of monoglycerides, diglycerides, propylene glycol fatty acid esters, sorbitan mono fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyalkylene and alkyl glyceryl ethers Or a mixture of two or more of them. However, the present invention is not limited thereto.

The alkanolamide according to the present invention can be represented by the following formula (1)

Wherein R ₁ is a C ₈ to C ₅₀ linear or branched fatty acid group or fatty alcohol group, R ₂ is hydrogen or a C ₁ to C ₁₀ linear or branched alkyl group, R ₃ is C ₁ ~ C ₁₀ alkyl group or the alkane can come due.

The oxidative hair dye composition of the present invention is a water-soluble gel type which is easy to apply to hair like a shampoo solution, has a high dyeing speed and excellent color sustainability, minimizes scalp damage, and is resistant to contamination such as hair dye, The material can be effectively removed.

Hereinafter, the present invention will be described in detail. The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms and the inventor may appropriately define the concept of the term in order to best describe its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.

Generally, the number and kinds of nonionic surfactants used in hair dyes vary widely. Among them, the nonionic surfactant contained in the oxidative dyeing composition of the present invention is a nonionic surfactant having a low HLB of about 12.0 or less as a non-ionic surfactant. When the HLB is 12.0 or less, there is no particular limitation, and it is possible to select an appropriate one in consideration of the smell and irritation of the hair dye and the balance in the total composition ratio during use. For example, the HLB may preferably be 2.0.

As described above, the nonionic surfactant having an HLB of 12.0 or less can be combined with the alkanolamide of the present invention at a high pH (pH 8.0 or higher) to form a moisture gel having a transparent or translucent opacity. Further, when mixed with a binder having a water content of 50% or more, the mixing viscosity can be easily controlled and the wet feeling can be maintained, which makes it possible to maintain the gel phase in a form that is easy to be applied in the hair.

Examples of the nonionic surfactant having an HLB of 12.0 or less include monoglyceride, diglyceride, propylene glycol fatty acid ester, sorbitan mono fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyalkylene, alkyl glyceryl ether And mixtures of two or more thereof, but are not limited thereto.

Among the above nonionic surfactants, polyoxyalkylene is preferably included. Examples of the polyoxyalkylene include lauryl alcohol or decyl alcohol to which EO (ethylene oxide) is added, polyoxyethylene, polyoxyethylene cetyl ether, polyoxyethylene (3) decyl ether, polyoxyethylene (2) Polyoxyethylene (3) lauryl ether, and polyoxyethylene (4) lauryl ether, or a mixture thereof.

 Such a polyoxyalkylene surfactant may be more suitable for the present invention because the polyoxyalkylene surfactant is heated up to 65 ° C or higher and then cooled to enhance the gelation property. These moisture gels are lightweight, softly applied, and strong in moisture. Thus, when a suitable polyoxyalkylene surfactant is employed, a medicinal agent having various viscosities can be produced.

The content of the nonionic surfactant according to the present invention may be 1.0 to 30.0% by weight, preferably 5.0 to 20.0% by weight based on the total weight of the composition. If the amount is less than 1.0% by weight, the effect of increasing the dyeing solution is very low, so that the usability is very poor and a significant dyeing effect can not be expected. If the amount is more than 30.0% by weight, The dyeability may be lowered.

The alkanolamide compound contained in the oxidative dyeing composition of the present invention can be stabilized when mixed with the lipophilic nonionic surfactant according to the present invention and can be easily adjusted Can have a characteristic that can be achieved. Therefore, it is possible to give a moisturizing effect and a conditioning feeling to the hair at a high pH, and to minimize the scalp irritation, thereby reducing the scalp damage.

As the alkanolamide which can be used in the present invention, the fatty acid amide compound represented by the above-mentioned formula (1) can be typically used. Examples of the compound represented by the above formula (1) include acetamide, cocamide, almondamide, behenamide, tallowamide, lauamide, (DEA), monoethanolamine (MEA), monoisopropanolamine (MIPA), 2- (2-hydroxyethyl) aminomethane, and the like, such as isostearamide, lactamide, lauramide and stearamide, But are not limited to, condensed forms of alkylaminoethanolamines.

The content of the alkanolamide compound according to the present invention may be 1.0 to 30.0 wt%, preferably 5.0 to 20.0 wt%, based on the total weight of the composition. If the content is less than 1.0% by weight, the effect of increasing the dyeing solution is very low, so that the usability is very poor and not a definite dyeing effect can be expected. If it exceeds 30.0% by weight, penetration of the dye into the hair can be inhibited.

In the present invention, the weight ratio of the nonionic surfactant and the alkanolamide is preferably 0.5: 1.0 to 1: 1.5, more preferably 0.8: 1.0 to 1.0: 1.2. This is because the gel having the moisture sensitivity within the above range is most easily formed and the feeling of use is very excellent.

The oxidative dyeing composition of the present invention may further contain an anionic surfactant in addition to the nonionic surfactant and the alkanolamide. The anionic surfactant included in the present invention, when used together with the nonionic surfactant and the alkanolamide, can rapidly apply the dyeing solution to the hair and exhibits properties similar to those of the shampoo immediately after dyeing, It is possible to impart the property of removing the hair dye and the scalp and the dye solution remaining on the skin more effectively without using the soap.

If the amount is less than 0.1% by weight, the dyeing solution remaining on the scalp or skin can not be easily removed. If the amount is more than 20.0% by weight, the hair dyeing agent is prevented from penetrating into the hair.

The oxidative hair dye composition of the present invention may further comprise an alkyl polyglycoside (Alkyl (C ₈ -C ₂₂ ) poly glycoside) in addition to the nonionic surfactant and the alkanolamide. The alkylpolyglycoside according to the present invention can be used in combination with the nonionic surfactants and alkanolamides described above to improve the stability of formulations by making the properties more transparent and to minimize the scalp and skin pollution.

The content of the alkyl polyglycoside may be 0.01 to 20.0 wt%, preferably 0.1 to 10 wt%, based on the total weight of the composition. If the content is less than 0.1% by weight, the effect on the stability of the formulation and the transparency of the formulation is very small.
