Description

TECHNICAL FIELD The present invention relates to a hair dye composition, and more particularly to a hair dye composition which is excellent in dyeing and has very little damage to hair. is there.

[Prior art and its drawbacks] As a hair dye, it has excellent dyeability on hair and
It is required that the hair is not damaged and the finish is good, but conventionally, a two-pack type oxidative hair dye has been widely used as a product having particularly excellent dyeing property to hair. The hair dye comprises, for example, a first agent containing an oxidizing dye intermediate such as paraphenylenediamine as a main agent and a second agent containing an oxidizing agent such as hydrogen peroxide as a main agent. In short, since this hair dye mixes and uses the first agent and the second agent immediately before hair dyeing, it has good storage stability, and since it uses an oxidative polymerization reaction, it is very dyeable to hair. Are better.

However, although this hair dye has excellent hair dyeing power, it generally causes large damage to the hair and poor finish. Therefore, the hair is not moisturized and the dyeing gives an unnatural color to a third party. There are drawbacks such as giving a feeling of strangeness and poor combability and less suppleness of hair.

Therefore, various compounding agents have been conventionally studied to improve such drawbacks, but in the case of a compounding agent capable of sufficiently preventing damage to hair, the compound strongly exhibits hair dyeing power as a hair dye. There are many things that hinder the effect of the hair dye itself,
Further improvement is desired. In addition, when blended with a two-pack type oxidative hair dye, unlike ordinary hair treatment agents, etc., it is necessary for it to exist stably during the oxidation reaction of the dye intermediate and exert its effect. The selection range will be greatly restricted.

[Problems and Solutions of the Invention] In view of the above-mentioned circumstances, the present invention, in particular, in a two-pack type oxidative hair dye, does not adversely affect the hair dyeing power, prevents hair damage, and prevents hair after dyeing. The purpose of the present invention is to provide a hair dye composition which gives a natural moisturizing finish, and the 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 described in detail.

The hair dye targeted by the present invention is a permanent hair dye such as an oxidative hair dye or a plant hair dye, or a semi-permanent hair dye such as a color lotion. The dosage form is liquid, cream, gel, paste,
Various forms such as powder, solid, aerosol, and aerosol foam form can be mentioned. Usually, the most widely used hair dye is an oxidative hair dye consisting of a first agent containing an oxidative dye intermediate as a main agent and a second agent containing an oxidant as a main agent. In the case of an oxidative hair dye, its improving effect is remarkable.

Examples of oxidative dye intermediates include phenylenediamines, aminophenols, toluylenediamines, aminonitrophenols, diphenylamines, diaminophenylamines, N-phenylphenylenediamines, diaminopyridines, and salts thereof. To 1 type, or 2 or more types. The amount of the oxidation dye intermediate compounded is usually about 0.01 to 10% by weight based on the total weight of the first agent. In addition, resorcin, pyrogallol, catechol, metaaminophenol, metaphenylenediamine and the like can be blended in the first agent as a coupler. And "Hair dye raw material standard" (revised third edition, issued in May 1985, issued by Japan Hair Color Industry Association, Hair Dye Conversation Society)
The compounding agents listed in 1. 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, oil components such as lanolin, squalane, liquid paraffin, sulfite, and ascorbic acid. Well-known ingredients such as stabilizers, carboxymethyl cellulose, xanthan gum, thickeners such as higher alcohols, aqueous ammonia, alkali agents such as alkanolamines, and perfumes can be appropriately added.

On the other hand, examples of the second agent oxidant include hydrogen peroxide,
Examples thereof include urea peroxide. An appropriate compounding agent such as a stabilizer such as phenacetin or EDTA, an oil or fat such as paraffin or higher alcohol, a surfactant, an acid, a pH adjusting agent or a fragrance may be added to the second agent.

When the above-mentioned two-pack type oxidative hair dye is used, the hair dyeing treatment can be performed by mixing the first agent and the second agent immediately before the hair dyeing treatment and applying the mixture to the hair. In the case of a semi-permanent hair dye, an acid dye or a basic dye is contained, and for example, a dyeing auxiliary such as lower alkylene carbonate, N-alkylpyrrolidone, benzyl alcohol, a thickener, a lower alcohol, an acid, etc. are required. It can be appropriately blended according to the above.

In the present invention, it is an essential requirement to mix the above-mentioned hair dye with abietic acid, rosin or a salt or derivative thereof. In short, by blending these compounds, hair dyeing treatment can be performed while preventing damage to hair, and a robust color tone can be obtained.

The abietic acid used in the present invention is widely distributed in natural resins such as rosin, dimer, balsam, cobal, acroid, and amber, and is obtained by extraction from these.
Further, preferred derivatives of abietic acid include esters of abietic acid such as methyl ester, ethyl ester, hydroxyethyl ester, glyceryl ester, hydroxyethyl sulfonic acid, hydroxyacetic acid, polyethylene glycol, etc .; ethanolamine, diethanolamine. , And amides with glycine and the like, and more preferable salts include alkali metal salts with sodium, potassium and the like; salts with organic bases such as ethanolamine and diethanolamine.

In the present invention, rosin or its salt or derivative can also be used. For rosin, turpentina collected from Pinus plants is steam distilled, turpentine oil is removed, and the residue is purified gum rosin and pine roots, wood rosin acidified by extracting the material with a solvent or an alkaline solution. However, any of these can be used. The main component of rosin is resin acid such as abithienoic acid and pimaric acid. Moreover, as a preferable derivative,
Esters such as methyl ester of resin acid, ethyl ester, hydroxyethyl ester, glyceryl ester, hydroxyethyl sulfonic acid, hydroxyacetic acid, polyethylene glycol, etc .; amides with ethanolamine, diethanolamine, glycine, etc., Further, preferable salts include alkali metal salts with sodium, potassium and the like; salts with organic bases such as ethanolamine and diethanolamine.

The compounding amount of these compounds is usually based on the total amount of hair dye,
The amount is 0.0001 to 20% by weight, preferably 0.001 to 10% by weight. If this blending amount is less than 0.0001% by weight, it is difficult to sufficiently prevent hair damage and to obtain moisturized hair. Conversely, if it is more than 20% by weight, the effect is not significantly different and it is economical. Not.
