Description

[Detailed description of the invention] Industrial applications The present invention relates to a hair dye and a pretreatment agent for the hair dye.

Prior Art and its Problems Due to the recent trend of heavy use of hair dryers on a daily basis, hair is becoming more susceptible to damage. Damaged hair can become uneven in color, and the color of the roots and ends of the hair may be significantly different. Hair dyes are often used not only to dye gray hair, but also to reduce uneven coloring. However, conventional hair dyes tend to cause uneven dyeing in damaged areas, further damage the hair, are difficult to adjust the dyed condition, and do not dye the hair too darkly, drastically changing the user's appearance. There is a drawback. Therefore, it is preferable to dye damaged hair little by little using a vegetable hair dye that does not affect the hair much and has a mild action. As such vegetable hair dyes, those containing extracts of plants such as henna and chamomile, and the active ingredient of logwood (hematin) have been conventionally used.

However, since the above hair dye materials are dissolved in hot water and used, it takes 20 to 40 minutes to dye the hair, the effect is weak, and the pH is adjusted to high in order to ensure product stability and express the effect. , it has disadvantages such as easy damage to hair.

Means for Solving the Invention As a result of research on hair dyes that are safe for the human body, can be easily and effectively dyed using vegetable ingredients with mild action, the present inventor has developed a dye with a specific composition. It has been found that the hair material can reduce or eliminate the drawbacks of conventional hair dyeing materials, and that even better hair dyeing effects can be obtained by using the following composition as a pretreatment agent for this hair dyeing material.

That is, an object of the present invention is to provide the following hair dye material.

[Plant extracts containing 0.05 to 1% by weight of copper chlorophyllin sodium and/or copper chlorophyllin potassium; and/or 0.1 to 10% by weight of tannins 1 to 1]
A hair dye containing 10% by weight and adjusted to pH 2.5 to 7.5. The copper chlorophyllin sodium and copper chlorophyllin potassium used in the hair dye of the present invention are stabilized by replacing magnesium in plant chlorophyll molecules with copper, and further incorporate sodium and potassium into the molecule to produce a water-soluble green color. It is a pigment.

Copper chlorophyllin sodium and/or copper chlorophyllin potassium are blended in the hair dye in an amount of 0.05 to 1% by weight. If the amount is less than 0.05% by weight, the hair dyeing effect will be weak, and if it exceeds 1% by weight, it will easily stain the skin, which is not preferable.

As the plant extract, one or more plant extracts that can be used for plant dyeing can be used. For example, tannins such as shu (Japanese root), Eijitsu (Japanese rose root), Gennoshoko, Gaiyou (Artemisia annua), Hamamelis, Chamomile, Rosumari, Arnica, Hypericum, tea, sage (Salvia), Cornflower, Calendula, Malva, and Eucalyptus. Mention may be made of extracts of plants containing These plant extracts,
To adjust the color tone, extracts such as henna, sardines, kujin, shikon, onion peel, indigo, madder, etc. can be added. Plant extracts can be obtained by conventional extraction methods, such as extraction using a solvent at room temperature or gentle heating, or concentration by heating or vacuum concentration after solvent extraction and adjusting the concentration with an appropriate solvent. Obtained by manipulation. Plant extracts contain tannins, flaphononides, saponins, and amino acids. In the present invention, the plant extract containing 0.1 to 10% by weight of tannin is used, and is incorporated in the hair dye 1 in an amount of 1.0 to 10% by weight. If the blending amount is less than 1.0% by weight, the hair dyeing effect will be weak and 10
Even if the amount exceeds % by weight, the hair dyeing effect will not be improved.

The hair dye of the present invention desirably contains a cationic surfactant in order to improve the feel and texture.

As the cationic surfactant, known ones may be used, such as alkyltrimethylammonium salts such as cetyltrimethylammonium chloride and stearyltrimethylammonium chloride, alkyldimethylammonium salts such as distearylmethylammonium chloride, and stearyl chloride. Examples include alkyldimethylbenzylammonium salts such as dimethylpensylammonium, alkylpyridium salts such as cetylpyridium chloride, and polyoxyethylenealkylamines such as polyoxyethylene laurylamine.

One or more of these surfactants can be blended in an amount of 1.5% by weight of the hair dye.

If more than 1.5% by weight is added, the hair dyeing effect may deteriorate.

Furthermore, in the hair dye of the present invention, preservatives and the like can be used in amounts normally incorporated in hair cosmetics such as conditioners and shampoos. As a preservative, resorcinol,
Phenols such as methyl p-oxybenzoate and propyl p-oxybenzoate; acids and salts thereof such as benzoic acid, salicylic acid, dehydroacetic acid, and sorbic acid; 3.4.4
Examples thereof include amides such as '-trichlorocarbanilide, quaternary ammonium compounds such as benzalkonium chloride, chlorhexidine gluconate, and photosensitive elements.

The hair dye of the present invention preferably contains 0.01 to 0.5% by weight of mononitroguaiacol or a salt thereof in order to improve the hair dyeing effect.

If the blending amount is less than 0.01% by weight, the effect will be weak;
If it exceeds 0.5% by weight, it tends to stain the skin.

The hair dye of the present invention is prepared by emulsifying the above-mentioned components in purified water using a known method, and then producing pigments such as citric acid, tartaric acid, ascorbic acid, triethanolamine, and isopropanolamine.
It is manufactured by adjusting the pH to 2.5 to 7.5 with a H-thinning agent. If the pH is outside this range, the hair dyeing effect will be weakened.

Yet another object of the invention is to provide 1 to 20% by weight of anionic and/or amphoteric surfactants, hydrochlorides, sulfates of iron, copper, aluminium, zinc, lead, tin, chromium, manganese and cobalt. , 0.02 to 1% by weight of at least one metal compound selected from carbonates, citrates, tartrates, and acetates, and 0.05 to 1% by weight of a sodium compound and/or a potassium compound, Another object of the present invention is to provide a pretreatment agent for hair dye according to claim 1, which has a pH adjusted to 4.5 to 8.5.

In the pretreatment agent of the present invention, known anionic surfactants and amphoteric surfactants can be used. Examples of anionic surfactants include alkylbenzene benzene sulfonates such as laurylbenzenesulfonic acid, and α-olefinsulfonate such as sodium α-olefin sulfonate.
- Olefin sulfonates (Coo~16), alkanesulfonates such as sodium pentadecane sulfonate, alkyl sulfates such as triethanolamine lauryl sulfate, polyoxyethylene alkyl ether sulfates such as ammonium polyoxyethylene lauryl ether sulfate, olein Examples include soaps such as potassium acid and alkylolamides such as coconut oil fatty acid jetanolamide. Examples of amphoteric surfactants include betaine-type amphoteric surfactants such as lauryldimethylaminoacetic acid betaine and 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, and amino acid-type amphoteric surfactants such as N-stearyl β-alanine. Examples include surfactants and sulfonic acid type amphoteric surfactants such as N-pal-michiru-N and N-dimethylaminopropylsulfonic acid. One type of the above-mentioned surfactants may be used alone or two or more types may be used in combination. The amount of anionic and/or amphoteric surfactant is usually 1 to 20% by weight of the pretreatment agent. If the blending amount is less than 1% by weight, it will not be possible to sufficiently remove oil and the like that impair the hair dyeing effect of the hair dye. Also, 20
If it is more than % by weight, your hands may get rough with normal use.

Metal compounds act as mordants and are used to ensure they do not have a negative effect on the human body, and are usually iron, copper, aluminum,
Hydrochlorides, sulfates, carbonates, citrates, tartrates and acetates of zinc, lead, tin, chromium, manganese and cobalt can be used. Such compounds may be used alone or in combination of two or more. The blending amount of the metal compound is 0.02 to 1% by weight of the pretreatment agent. If the amount is less than 0.02% by weight, the mordant effect will not be sufficient, and if it exceeds 1% by weight, the pretreatment agent will not foam well, making it difficult to spread it evenly over the hair. .

Sodium and/or potassium compounds act as mordant aids, sodium and potassium carbonates,
Examples include inorganic compounds such as hydrogen carbonates, nitrates, hydrochlorides, sulfates, phosphates, and oxides, and organic compounds such as citrates and salicylates. These compounds may be used alone or in combination. Sodium and/or
Alternatively, the amount of the potassium compound added is usually 0.05 to 1% by weight. If the amount is less than 0.05% by weight,
The mordant auxiliary effect is not sufficient, and if it exceeds 1% by weight, the texture of the finished product may be impaired.

The pretreatment agent of the present invention can contain a known preservative, similar to the hair dye described in Section 2.

Further, the pretreatment agent of the present invention can be combined with a known metal sequestering agent in an amount used in hair cosmetics such as shampoo. Examples of the sequestering agent include disodium edetate, sodium citrate, sodium polyphosphate, sodium metaphosphate, and gluconic acid.

The pretreatment agent of the present invention is prepared by dissolving or emulsifying/solubilizing the above-mentioned components in purified water using a known method and mixing them uniformly. pH adjusters such as p)I
It is manufactured by adjusting it to 4.5 to 8.5. Although it does not affect the hair dyeing effect even if it is outside the pH range of 2.
If it is less than H4.5, the foaming and cleaning power will decrease,
When the pH exceeds 8.5, alkaline stress is applied to the hair.

According to the present invention, hair can be dyed by using the above-mentioned hair dye alone as a conditioner, but when the above-mentioned hair dye is used as a conditioner and the above-mentioned pretreatment agent is used as a shampoo, it is particularly effective and short. You can easily dye your hair in just a few minutes. This is due to the metal compounds and sodium and/or potassium compounds contained in the pretreatment agent,
This is because it provides a pre-mordanting effect on the pigment component contained in the hair dye. Further, the pre-treatment agent for the second and subsequent treatments has a post-mordanting effect on the hair dye used for the first treatment, and the hair dyeing effect is further improved by overcoating the hair dye thereon.

A method for dyeing hair using the hair dye and pretreatment agent of the present invention can be carried out, for example, by the following method.

First, depending on the length and amount of hair, use a pre-treatment agent of 101%.
Apply ~30ml to hair, lather to distribute evenly, leave for 2-3 minutes, then rinse with water. Apply approximately the same amount of hair dye on top of this and spread it evenly, 2 to 3 times.
Rinse with water after incubating for a minute.

Effects of the Invention The hair dye of the present invention provides excellent hair dyeing effects without adversely affecting scalp hair. The hair dye of the present invention dyes hair with simple operations and under mild conditions, so hair can be naturally dyed little by little and hair can be dyed frequently and repeatedly. According to the present invention, even better hair dyeing effects can be obtained in a simple manner by using the pretreatment agent of the present invention prior to using the hair dye.
