Description

[0001] The present invention relates to a hair cosmetic composition containing natural dyeing ingredients,

The present invention relates to a cosmetic composition for hair containing natural dye components, and more particularly to a cosmetic composition for hair which has a mucuna extract and a low molecular phenol as a coloring agent and contains a water-soluble metal compound as a mordant agent and has excellent dyeing effect on hair .

The cause of irritation in the hair dye composition for oxidation dyeing is largely a reducing agent and an alkali agent, and ammonia which is an alkaline agent is the most important cause.

Examples of the alkaline agent to be contained in the formula 1, the formula 2 or the formula 3 of the hair dye include ammonia, ethanolamine, carbonate and the like. However, the ethanolamine is highly persistent and has defects such as hair damage and skin irritation. It has a drawback that it can not brighten the hue of the hair because the effect of strengthening the decolorizing power or salt strength by hydrogen peroxide is weak. On the other hand, since ammonia does not remain on hair or scalp, and does not cause hair damage or skin inflammation, it is excellent in safety. Further, since ammonia has a property of sufficiently strong decolorizing power and salt strength of hydrogen peroxide, .

However, since ammonia peculiarly irritating odor is produced at the time of the procedure, especially when the lightness of the hair is increased, it is necessary to mix a large amount of ammonia. Therefore, the ammonia has a strong irritating odor and has a great disadvantage of imparting discomfort. If the amount of ammonia is simply lowered in order to overcome such drawbacks, there is a problem that the decolorization or dyeing performance is significantly deteriorated.

Mucuna pruriens , on the other hand, is a tropical first-year soybean plant, also called velvet bean. Mukunapururiense is used as a feed and has a nitrogen fixation capability that can fertilize the soil. It can also be used as a coffee substitute called "Nescafe", and it has also been used for pharmacological purposes such as antidepressants and antidepressants. It is also a source of dopa that is converted to dopamine, a neurotransmitter in the brain. Dopaminergic depression is associated with Parkinson's disease. In people with Parkinson's disease, brain cells that produce dopamine are destroyed. Mucuna pruriente also contains bufotenine, a release of cholinesterase, and serotonine, a neurotransmitter involved in learning, sleeping, and controlling mood.

The seeds of Mukunapururiense are black or brown. To use Mukunapururiensu extract extracted from them, an alkaline agent and oxidizing agent should be used for hair dyeing. Alkali agents and oxidants may cause scalp stimulation and hair damage There is a problem in that the coloring power of the mukuna extract and the hair adhesion are weak and the dyeing effect and the color sustainability are inferior to the general hair dye.

Therefore, the present inventors intend to increase the dyeing power without using an ammonia, which is a specific irritant odorant, and to quickly and easily dye the hair, to reduce the stimulation to the scalp and minimize hair damage by using a natural dye component, The present inventors have found that the use of a water-soluble metal compound as a mordanting agent increases the dyeing effect and color persistence of hair with the use of a low molecular weight phenol compound together with a plant extract, mucuna pruriente extract and a mordanting agent.

Accordingly, it is an object of the present invention to provide a cosmetic composition for hair which uses Mucuna pruriente extract, which is a plant extract, as a coloring agent to enhance safety against hair and scalp, has excellent hair dyeing effect and color persistence, and is easy to use .

In order to achieve the above object, the present invention provides a hair cosmetic composition containing mucuna extract, low-molecular phenols and a water-soluble metal compound.

The present invention can increase the safety of hair and scalp by using natural dye components, can provide excellent dyeing effect and color sustainability, and can be provided as a form such as shampoo, which is convenient for use.

The present invention relates to a cosmetic composition for hair containing mucuna extract, low-molecular phenols and a water-soluble metal compound, wherein the mucuna extract and phenols are used as a coloring agent and the water-soluble metal compound is used as a mordant. In addition, the composition of the present invention is formulated into a two-part formulation, which is a two-component formulation containing a water-soluble metal compound and an agent containing a water-soluble metal compound, It consists of a two-component system containing a Kuna extract and a low-molecular-weight phenol.

Hereinafter, the present invention will be described in more detail. However, for convenience, the composition of the present invention will be described based on that the coloring agent is included in the first agent and the mordant agent is included in the second agent.

The mucuna extract used in the present invention is preferably extracted from the seeds of Mucuna pruriens .

The extraction method of Mukuna extract used in the present invention may be an extraction method used in the art, and an exemplary extraction method is as follows.

The seeds of Mukunapururians were thoroughly dried, and then water or an organic solvent was added thereto, followed by reflux extraction for deposition. Thereafter, the residue and the filtrate were separated by filtration and centrifugation through a filter cloth, and the separated filtrate was concentrated under reduced pressure to remove the solvent. The concentrate was lyophilized to obtain Mukuna extract. The organic solvent used in the present invention may be selected from the group consisting of ethanol, methanol, butanol, ether, ethyl acetate, chloroform, and a mixed solvent of these organic solvents and water, preferably 80% ethanol.

In the composition of the present invention, mucuna extract is contained in an amount of 0.1 to 5.0% by weight based on the total weight of the composition of one agent.

If it is used in an amount of less than 0.1% by weight, it is not effective in improving dyeability and color persistence. If it exceeds 5.0% by weight, the extract may be precipitated or precipitated in supernatant while being supersaturated.

In the composition of the present invention, low molecular weight phenols are used together with mucuna extract as a coloring agent. The low-molecular phenols include, but are not limited to, at least one selected from the group consisting of gallic acid, salicylic acid, catechin, catechol, vanillin, vanillic acid, ferulic acid, The low molecular weight phenols are contained in an amount of 0.1 to 10% by weight based on the total weight of the composition of one agent. If it is used in an amount of less than 0.1% by weight, it is not effective in improvement in dyeability and color persistence. If it is more than 10.0% by weight, the low molecular weight phenols may be precipitated or precipitated in the form of a supersaturated solution.

The molecular weight of the low molecular weight phenols used in the present invention is in the range of 90 to 500 g / mol. When the molecular weight exceeds 500 g / mol, the dye can not penetrate into the hair cuticle layer, It does not develop color. Therefore, the molecular weight of the low molecular weight phenol is preferably within the above range.

In the composition of the present invention, a water-soluble metal compound is used as a mordant. The water-soluble metal compound is not limited thereto, but is at least one selected from the group consisting of ferrous chloride, ferric chloride, ferrous sulfate and ferric sulfate. The water-soluble metal compound is contained in an amount of 0.1 to 10% by weight based on the total weight of the composition of the two agents. If it is used in an amount of less than 0.1% by weight, it is not effective in improving dyeability and color persistence. If it is more than 10.0% by weight, the water-soluble metal compound may be precipitated or precipitated in supernatant while supersaturated and dissolved. .

The composition for hair of the present invention may be composed of one or two agents and may be formulated into hair tonic, hair nutrition lotion, hair essence, hair serum scarf treatment, hair treatment, hair conditioner, hair shampoo, hair lotion, . It may also contain suitable ingredients depending on the formulation.

[Test Example 1] Dyeing force evaluation

To evaluate the dyeing powers of Examples 1 to 2 and Comparative Examples 1 to 3, hair tresses having a length of 12 cm and a weight of 1 g containing 30% of gray hair were thoroughly soaked in water, and then the amounts of the first and second samples were the same 5 g each was taken, mixed and shampooed. After 3 minutes, it was washed with running water for 1 minute and then dried using a hair dryer. After repeating the above procedure 10 times, the dried hair was measured for color using a color difference meter (model: Hunterlab Labscan XE). The results were compared using the change of L * value before and after the shampoo measured by the colorimeter. L * value is a value indicating the lightness, and the larger the L * value, the brighter the color. Therefore, the larger the ΔL * value, the difference in brightness before and after shampooing, means the darker the color is expressed and the better the dyeing power. The results are shown in Table 2 below.
