Abstract

PURPOSE:To obtain a hair dye composition capable of preventing injuring of hair without impairing dyeing effects as a hair dye agent and providing moistened hair having natural color by blending abietic acid, rosin or salt thereof or derivative thereof with the hair dye agent. CONSTITUTION:The objective hair dye composition obtained by blending a hair dye agent with abietic acid, rosin or salt thereof or derivative thereof widely distributed in natural resin such as rosin, dimmer or balsam. The hair dye agent composition can prevent injuring of hair without impairing moistened hair having natural color and as a result, moistened hair having natural color can be obtained. Moreover, the composition exhibits excellent effect also in combing smoothness. When these additives are blended with a hair dye agent, these additives stably exist in oxidation and polymerization of oxidation dye intermediate and provide good dyeing performance and finish of hair.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair dye composition, and more specifically, to a hair dye composition that has excellent coloring properties and causes extremely little damage to the hair. be.

[Prior art and its drawbacks] Hair dyes are required to have excellent hair dyeing properties, do not damage the hair, and give a good finish. As something that
Two-component oxidative hair dyes are widely used. This hair dye consists of, for example, a first part containing an oxidation dye intermediate such as paraphenylenediamine as a main ingredient, and a second part containing an oxidizing agent such as hydrogen peroxide as a main ingredient. In short, this hair dye has good storage stability because the first and second agents are mixed together just before hair dyeing, and because it uses an oxidative polymerization reaction, it has very good dyeability on hair. Are better.

However, although this hair dye has excellent hair dyeing power, it generally causes a lot of damage to the hair and gives a poor finish. It has the disadvantage that it gives a strange feeling to the hair, and also that it is difficult to comb and the hair loses its suppleness.

Therefore, various compounding agents have been researched in order to improve these drawbacks, but in the case of compounding agents that can sufficiently prevent hair damage, it is possible to demonstrate robust hair dyeing power as a hair dye. There are many things that inhibit the effect of the hair dye itself, and further improvements are desired. In addition, when blending into a two-component oxidative hair dye, unlike ordinary hair treatment agents, it must exist stably during the oxidation reaction of the dye intermediate and exhibit its effect. The selection range will be greatly restricted.

[Problems to be solved by the invention and means for solving the problem] In view of the above-mentioned circumstances, the present invention provides a two-component oxidative hair dye that does not adversely affect the hair dyeing power, prevents damage to the hair, and improves the quality of the hair after dyeing. The object of the present invention is to provide a hair dye composition that gives a moist and natural finish, and this object of the present invention is achieved by incorporating abietic acid, rosin, or a salt or derivative thereof.

Hereinafter, the configuration of the present invention will be explained in detail.

Hair dyes targeted by the present invention include permanent hair dyes such as oxidative hair dyes and vegetable hair dyes, and semi-permanent hair dyes such as color lotions. The dosage form includes various forms such as liquid, cream, gel, paste, powder, solid, aerosol, and aerosol foam.

Normally, the most widely used hair dye is an oxidative hair dye consisting of a first part containing an oxidation dye intermediate as the main ingredient and a second part containing an oxidizing agent as the main ingredient. In the case of oxidative hair dyes, the improvement effect is remarkable.

Examples of oxidation dye intermediates include phenylenediamines, aminephenols, tolylenediamines, aminonitrophenols, diphenylamines, diaminophenylamines, N-phenylphenylenediamines, diaminopyridines, and salts thereof. One or more types can be mentioned. The amount of this oxidation dye intermediate is usually 0.01 to 10% by weight based on the total weight of the first agent.
That's about it. Moreover, resorcinol, pyrogallol, catechol, meta-aminophenol, meta-phenylenediamine, etc. can be blended into the first agent as a coupler. Also, compounding agents listed in the "Standards for Hair Dye Raw Materials" (revised box; edition, published May 1985, published by the Japan Hair Color Industry Association and the Hair Dye Association) can also be used. Furthermore, for example, surfactants such as polyoxyethylene alkyl ether and polyoxyethylene alkylamine fatty acid amide, humectants such as glycerin and propylene glycol, oily components such as lanolin, squalane, and liquid paraffin, sulfites, ascorbic acid, etc. Known ingredients such as stabilizers, thickeners such as carboxymethyl cellulose, xanthan gum, and higher alcohols, alkali agents such as aqueous ammonia and alkanolamines, and fragrances may also be appropriately incorporated.

On the other hand, examples of the second agent oxidizing agent include hydrogen peroxide and urea peroxide. Appropriate compounding agents such as stabilizers such as zenacetin and EDTA, oils and fats such as paraffin and higher alcohols, surfactants, acids, pH adjusters, and perfumes can also be blended into the second agent.

When using the above-mentioned two-component oxidative hair dye, the hair dyeing process can be carried out by mixing the first part and the second part and applying the mixture to the hair immediately before the hair dyeing process.

In addition, in the case of semi-permanent hair dyes, they contain acidic dyes or basic dyes, such as lower alkylene carbonate, N
- Dyeing aids such as alkylpyrrolidone and benzyl alcohol, thickeners, lower alcohols, acids, etc. may be appropriately blended as required.

In the present invention, abietic acid,
It is an essential requirement to blend rosin or a salt or derivative thereof. In short, by incorporating these compounds, hair can be dyed while preventing damage to the hair, and moreover, it is possible to obtain a strong color tone.

Abietic acid used in the present invention is widely distributed in natural resins such as rosin, dimer, balsam, copal, acroyd, and amber, and can be extracted from these. Preferred derivatives of abietic acid include esters of abietic acid such as esters with methyl ester, ethyl ester, hydroxyethyl ester, glyceryl ester, hydroxyethylsulfonic acid, hydroxyacetic acid, polyethylene glycol, etc.; Examples include amides with tanolamine, glycine, etc., and further preferable salts include alkali metal salts with sodium, potassium, etc.; salts with organic bases such as ethanolamine, jetanolamine, etc.

Further, in the present invention, rosin or a salt or derivative thereof can also be used. The rosin is made by steam-steaming turpentine collected from plants of the genus Matus and removing the turpentine oil.
Gum rosin, which is the purified residue, and the root stock of a Pinus genus plant,
Wood rosin is made by extracting wood with a solvent or alkaline solution and making it acidic, but any of these can be used. The main components of rosin are resin acids such as abietic acid and pimaric acid. Preferred derivatives include esters such as esters of resin acids with methyl ester, ethyl ester, hydroxyethyl ester, glyceryl ester, hydroxyethylsulfonic acid, hydroxyacetic acid, polyethylene glycol, etc.: ethanolamine, jetanolamine, Preferred salts include alkali metal salts with sodium, potassium, etc.; and salts with organic bases such as ethanolamine and jetanolamine.

The amount of these compounds added is usually 0 to the total amount of hair dye.
．． 0001-20% by weight, preferably 0°001-10
It is the weight percent. If the blending amount is 0.0001% by weight without swirling, it is difficult to sufficiently prevent hair damage and make 1q of moisturized hair.
There is no big difference in effectiveness and it is not economical.

(Effects of the Invention) According to the hair dye composition of the present invention, hair damage can be prevented without impairing the dyeing effect as a hair dye, and as a result, hair with a moisturized natural color can be obtained. It has an excellent effect of being able to be easily combed. It is well known that abietic acid, rosin, etc. are added to permanent waving agents, but when added to hair dyes, they stably exist during the oxidation and polymerization of the oxidation dye intermediate, resulting in poor coloring and coloring of the hair. The fact that the finish is improved is an unexpected effect.
