Description

[Detailed description of the invention]

■Unokai Fishing [Industrial Application Field] The present invention relates to a hair dye composition, and more particularly to a metal hair dye composition. [Prior Art] As metal hair dyes, those containing metal compounds such as iron, copper, silver, and bismuth are known. For example, the first agent contains sulfite, etc., and the second agent contains iron salt and hydroxy compound.
There is a metal hair dye consisting of a dye. With this type of hair dye, first apply the first agent to the hair, and then apply the second agent.In this way, the metal ions in the second agent combine with hydroxy compounds in the hair to form color. Hair dyes that cause a reaction and dye the hair (people who have an allergic reaction to hair dyes containing organic oxidative dyes because they do not cause irritation or sensitization to the body) [Problems to be Solved by the Invention] However, the above-mentioned metal hair dyes (compared to hair dyes containing organic oxidation dyes) have inferior hair dyeing power, and also lack luster and mellowness. The present invention aims to solve the above problems and provide a metal hair dye composition that has excellent hair dyeing power and can dye hair to a natural color. The structure of the present invention that achieves the above purpose will be explained below. [Means and effects for solving the problem] Summary of the present invention (

Further, when the first agent contains the above salts and the above dye as the same composition, a quinoline dye is used from the viewpoint of storage stability of the hair dye. In addition to quinoline dyes, azo dyes, xanthene dyes and nitro dyes can be used since storage stability problems due to single dyes are eliminated when they are made into separate compositions. The first agent (usually based on a solution such as water, in this case,
The amount of the above-mentioned salts, which are essential ingredients, in the first part (the total amount of the first part, whether or not it is divided into separate compositions, is usually 0.1 to 20% by weight, preferably 0.5 to 20% by weight)
It is 10% by weight. In addition, the amount of the above-mentioned essential coloring matter is usually 0.0 as the entire first agent, whether or not it is divided into separate compositions.
It is 5 to 2.00% by weight. If the blending amount is less than 0.05% by weight, no significant improvement in hair dyeing power or dyeing properties can be expected, and even if it is greater than 2.00% by weight, the improvement in the effect will be small compared to the amount, making it economical. Not on point. In addition, when the first agent is divided into a composition containing salts and a composition containing dye (the mixing ratio of both groups is 1:0,001 to 1:0,001).
2 is preferred. Moreover, the first agent usually contains an alkaline agent. By containing this, when the first agent is applied to the hair, the hair swells, and the second agent is then applied to the hair (f).The second agent can easily penetrate into the hair. , ammonia, alkanolamines such as monoethanolamine, and alkali hydroxides such as sodium hydroxide.The amount of the alkaline agent in the entire first agent (usually 0.5 to 10% by weight). Depending on the agent, the pH of the first agent is usually 8 to 1.
It is said to be around 3. When the first agent is divided into separate compositions (i.e., the alkaline agent may be incorporated into both or either one of them). The agent contains iron salts and hydroxy compounds as essential components. Specific examples of iron salts include ferrous sulfate, ferrous chloride, ferrous acetate, ferrous phosphate, and ferrous oxalate. Examples include ferrous salts such as ferrous nitrate, ferrous citrate, ferrous carbonate, and ferrous birophosphate. In addition, if necessary, along with iron salts, for example, lead, silver,
Metal salts such as bismuth and aluminum can also be added. Examples of the hydroxy compound include gallic acid, gallic acid esters such as propyl gallate, tannin esters such as tannic acid and ethyl tannate, pyrogallol, catechol, and hydroquinone. The second agent also usually uses a solution such as water as a medium, and in this case, the amount of iron salt in the second agent is usually 0.1 to 20% by weight, preferably 1.0 to 10% by weight, and the hydroxy compound The blending amount in the second agent is usually 0.1 to 10% by weight, preferably 0.5 to 6% by weight. In addition, the second agent contains a water-soluble surfactant that improves hair penetration, and the second agent contains a water-soluble surfactant that improves hair penetration, and the first agent contains a water-soluble surfactant that improves hair penetration.
A reducing agent may be included before mixing with the agent. Examples of the surfactant include higher alkylbenzene sulfonates, sulfonated esters of alcohols and polybasic acids, taurate fatty alcohol sulfates, polyoxyethylene alkyl ethers, alkylphenoxypolyoxyethylene ethanols, and the like. The blending amount of these components is usually 0 to 10% by weight in the second agent. In addition, the reducing agents listed in Table 1 include glucose, sorbic acid, citric acid, lactic acid, salicylaldehyde, thiosalicylic acid, sodium hypophosphite, sodium sulfite, sodium bisulfite, ascorbic acid, ascorbic acid derivatives, cysteine, thioglycolic acid, etc. It will be done. The blending amount of these components is usually 0.01 to 1.0% by weight in the second agent. Note that the second agent is usually acidic (pH 1 to 6) due to iron salts, hydroxy compounds, and the like. For the hair dye composition of the present invention, for example, the following components can be appropriately blended into the first agent, the second NL, or both agents. Furthermore, when the first agent is divided into separate compositions, the following components may be blended into both of them, or may be blended with either one of them. ■Higher alcohol (gives shine and texture to hair after dyeing): Examples include cetyl alcohol, stearyl alcohol, and behenyl alcohol. ■Cationic polymers (those that make hair easier to comb after dyeing): Examples include quaternary nitrogen-containing cellulose ethers. ■ Thickeners (things that give hair dye a suitable level of viscosity and increase its adhesion to hair): Examples include carboxyvinyl polymer carboxymethyl cellulose, hydroxyl ethyl cellulose, xanthan gum, carrageenan,
Sodium alginate, pectin, pullulan, farcelan, gum arabic, gum gatchi, gum tragacanth,
One example is the end of agar. ■Oils (things that give the hair a soft feel after dyeing): Examples include liquid paraffin, silicone oil, squalane, lanolin, and petrolatum. (2) Humectants: Examples include glycerin, propylene glycol, polyethylene glycol, 1,3-butylene glycol, dipropylene glycol, and sorbitol. ■Hair protectants: Examples include polypeptides, lecithin, and mucopolysaccharides. To dye hair using the hair dye composition of the present invention, apply the first agent to the hair, leave it for 20 to 30 minutes, then apply the second agent and leave it for another 20 to 30 minutes. Then, it is recommended to wash with water. In addition, if the first agent is divided into separate compositions, mix them in a predetermined ratio in advance, and then add the first agent.
Used as an agent. In this treatment, the first agent adheres to the hair, and the second agent
When the agent is applied, ferrous ions are liberated in the hair,
This is oxidized to ferric ions, which then react with hydroxy compounds to form insoluble dyes. The pigment and the essential pigment are mixed and fixed on the hair to dye the hair.
