Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is easy to apply to hair, has an excellent conditioning effect, greatly improves the luster, finger touch and smoothness of the hair, and gives the hair a calm and good texture and naturally. The present invention relates to a hair rinse composition having an effect of coloring hair.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
Since the gloss and fingers of the hair after washing the hair are poor,
A hair treatment agent called a hair conditioner or a hair conditioner is applied to give a conditioning effect to the hair after washing. These treating agents are generally those containing quaternary ammonium salts such as stearyltrimethylammonium chloride and higher alcohols as main components, and various additives are added to further enhance the effect. ..

On the other hand, among those who use these hair treatment compositions, the hair becomes gray due to aging, or the hair is damaged by brushing, perming, etc.
The natural hair color may have changed. In order for these people to return their hair to the original color, it is most effective to dye the hair with a hair dye such as an acid dye or an oxidation dye.
However, it is easy to see that they are complicated to operate and that they are dyed by a third party because the hair color changes abruptly. Further, there is a problem that a boundary is formed between the treated portion and new hair as the hair grows, resulting in an unfavorable appearance. As such, they wanted a gradual natural change in hair color without abrupt color change. Furthermore, if the hair treatment composition such as the above-mentioned hair rinse, which has become a daily lifestyle, imparts a high conditioning effect such as gloss or finger contact to the hair, and if these things can be performed, the complexity is eliminated. And are considered more useful. As means for achieving these things, Japanese Patent Laid-Open Publication No.
7-23543 and JP-A-59-231009.
Although the publications have been proposed, they use an oxidative dye as a dye and have a problem that they cannot be used by a person having a sensitizing property. Further, JP-A-1-132512 proposes a dye using a basic dye and a neutral dye, but a sufficient dyeing power cannot be obtained. Further, Japanese Patent Laid-Open No. 1-308215 has been proposed as a method using an acid dye, but it contains a quaternary ammonium salt having a branched chain as an essential component and is effective for improving the texture as a hair rinse. However, an acidic dye which is anionic and a quaternary ammonium which is cationic form an insoluble salt, so that sufficient dyeing power cannot be obtained and there is a problem in stability.
Therefore, it is the actual situation that a product having the above-mentioned effect is not obtained until now.

[0004] That is, the present invention is a hair conditioner which is easy to apply to hair and has a high conditioning effect, which greatly improves the luster, finger touch and smoothness of the hair and gives the hair a calm and good texture. An object of the present invention is to provide a hair rinse composition capable of naturally coloring hair, such as making a gray hair black and making the gray hair inconspicuous for a person with white hair.

[0005]

The hair rinse composition of the present invention which achieves the above object has the following constitution. That is, (A) the following general formula (1)

[Chemical 3] [Wherein R ₁ is a hydrogen atom, a methyl group or a methoxy group,

(CH _{3) 2} OH _{group, -CH 2 CH (CH 3)} OH group,
It represents a -CH (CH ₃₎ CH ₂ OH group, -CH = CHCH ₂ group or -OCH ₂ CH ₂ OH group. ] One or more aromatic alcohols selected from the group of
A group of aliphatic hydrocarbons having a straight chain or a branched chain or an aliphatic alcohol represented by the general formula (2) R-OH (R is an aliphatic hydrocarbon having a straight chain or a branched chain having 12 to 24 carbon atoms). One or more components selected from (C)
The following general formula (3)

[Chemical 4] [In the formula, all of R ₃ are methyl groups or a part thereof is a phenyl group, all of R ₄ are methyl groups or one of them is a hydroxyl group, and n is 200 to 2000. ] One or more types of silicone represented by: and (D) xanthan gum and / or hydroxyethyl cellulose,
(E) A hair rinse comprising polyethylene glycol having an average molecular weight of 20,000 to 800,000, (F) an acid dye, and (G) an acid, and having a pH of 2.0 to 5.5. It is a composition.

Examples of the aromatic alcohol represented by the general formula (1) in the present invention include benzyl alcohol, phenethyl alcohol, γ-phenylpropyl alcohol, cinnamic alcohol, anis alcohol, P-methylbenzyl alcohol and α-α. -Dimethylphenethyl alcohol, α-phenylethanol, phenoxyethanol and the like.

In the hair rinse composition of the present invention, one or more of these aromatic alcohols is preferably 0.5 to 15.0% by weight (hereinafter abbreviated as wt%) based on the total amount of the composition. Is blended. 0.5 wt%
If it is less than 0.1%, it is difficult to obtain a sufficient effect for coloring hair, and if it exceeds 15% by weight, stickiness and a strong aromatic alcohol odor occur, which tends to be sensory unfavorable.

Examples of the aliphatic hydrocarbon or the aliphatic alcohol of the general formula (2) in the present invention include petrolatum, liquid paraffin, liquid isoparaffin, squalane, squalene, lauryl alcohol, 2-hexyldecanol, oleyl alcohol and 2-octyldotheca. There are nols and isostearyl alcohol.

In the hair rinse composition of the present invention, one or more of these components are preferably contained in the total amount of the composition,
0.1 to 5.0 wt% is blended. If it is less than 0.1% by weight, it is difficult to obtain a sufficient effect to give calmness to the hair and to improve the texture, and if it exceeds 5.0% by weight, stickiness is generated and it tends to be organoleptically unfavorable. It becomes difficult to maintain stability.

Examples of the silicon represented by the general formula (3) in the present invention include dimethylpolysiloxane,
Examples thereof include methylphenylpolysiloxane, terminal hydroxyl group-containing dimethylpolysiloxane, terminal hydroxyl group-containing methylphenylpolysiloxane, and the average degree of polymerization n of these silicons is 200 to 2000. Those having an average degree of polymerization of less than 200 do not have a conditioning effect such as gloss and finger touch, and those having an average degree of polymerization of more than 2000 lose the smoothness after continuous use, which is not preferable.

In the hair rinse composition of the present invention, one or more of these components are preferably contained in the total amount of the composition,
0.05 to 5.0 wt% is blended. If it is less than 0.05% by weight, it is difficult to obtain sufficient effect to improve the smoothness of the hair by giving gloss to the hair, and if it exceeds 5.0% by weight, stickiness is generated and it tends to be organoleptically unfavorable. It becomes difficult to maintain the stability of the composition.

Xanthan gum and hydroxyethyl cellulose, which are water-soluble polymer compounds in the present invention, are
It is blended for the purpose of making it easy to apply to hair and stabilizing the system. For example, hydroxyethyl cellulose having an average degree of polymerization of 400 to 1000, such as that sold by KELCO, USA under the trade name of keltrol. There is xanthan gum, which is a polysaccharide composed of D-glucose, D-mannose, and D-glucuronic acid.

In the hair rinse composition of the present invention, these polymer compounds may be added alone or in combination, but it is more preferable to contain both of them from the viewpoint of appearance of the composition and ease of application. Further, these are preferably blended in an amount of 0.2 to 4.0 wt% with respect to the total amount of the composition. If it is less than 0.2 wt%, the system becomes unstable, and it separates over time and it is difficult to apply it to the hair. If it exceeds 4.0 wt%, stickiness occurs and the viscosity of the composition increases, so It tends to be difficult.

The polyethylene glycol in the present invention is intended to make it easy to apply to the hair by giving a slip during application, and to evenly color the hair because the composition is evenly applied on the hair. The average molecular weight is 20,000 to 8
It is 0,000. If the average molecular weight is less than 20,000, there is no effect, and if it exceeds 800,000, stickiness occurs, and it is organoleptically difficult to use. Further, the blending amount thereof is preferably 0.001 wt% to 0.1 wt% with respect to the total amount of the composition, and if it is less than 0.001 wt%, the effect is not obtained.
If it exceeds 0.1 wt%, stickiness is generated, and it tends to be sensory unfavorable.

The acidic dye in the present invention is mainly a tar-based dye, and is roughly classified into a nitro dye,
Examples include azo dyes, nitroso dyes, triphenylmethane dyes, xanthene dyes, quinoline dyes, anthraquinone dyes and indigoid dyes.

The hair rinse composition of the present invention preferably contains 0.005 to 0.2 wt% of one or more of these acidic dyes, based on the total amount of the composition.

Examples of the acid in the present invention include citric acid, salicylic acid, acetic acid, lactic acid, propionic acid, tartaric acid, phosphoric acid, hydrochloric acid and the like, and the compounding amount thereof is such that the pH of the composition is 2.0 to 5.5. It is a necessary amount to adjust. If the pH is lower than 2.0, there is a problem in stability, and the pH is 5.5.
If it is higher, sufficient effect for coloring hair cannot be obtained.

Further, the hair rinse composition of the present invention contains the above-mentioned components as essential components, but other components can be appropriately added to the composition within a range that achieves the object of the present invention.

That is, ester oil such as isopropyl myristate, isopropyl palmitate, camellia oil, vegetable oil such as olive oil, avocado oil, jojoba oil, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene sorbitan monolaurate Nonionic surfactants such as propylene glycol, dipropylene glycol, 1.3-butylene glycol, humectants such as glycerin, preservatives, chelating agents, fragrances, etc., and one or more of these are blended.
