Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of hair cosmetics. More specifically, the present invention relates to a hair cosmetic capable of adhering and repairing split ends of hair while imparting excellent gloss to the hair and providing a smooth feel.

[0002]

2. Description of the Related Art Conventionally, when using hair cosmetics to impart gloss and smoothness to hair, for example, oils such as silicone oil, ester oil, and hydrocarbon oil are solubilized, emulsified or dissolved. Attempts have been made to add the desired gloss and smoothness to hair by the action of these oils by adding them to hair cosmetics by the means described above. In particular, silicone oils generally have a low surface tension and, by using them, are excellent in conformity to hair and can provide excellent gloss. Therefore, silicone oils are widely used in recent years as components of hair cosmetics.

In general, hair is frequently and repeatedly subjected to hair washing, brushing, heat treatment with a drier, hair coloring, a bleaching agent, etc.
Severe damage and deterioration, as a result,
It is well known that it causes an increase in split ends, cut hairs, hair loss and the like and a decrease in strength.

[0004] Therefore, conventionally, for the purpose of protecting and repairing the above-mentioned hair damage, various raw materials extracted from natural products, such as proteins, polysaccharides, extracted extracts, and natural products, have been used as bases in hair cosmetics. Molecules, simple substances or oligos (for example, amino acids, peptides, etc.) constituting these are used.

For the purpose of imparting gloss and smoothness to hair while preventing damage to the hair, Japanese Patent Application Laid-Open No.
JP-183517, JP-A-63-24301, JP-A-63-313712, JP-A-5-85
As disclosed in Japanese Patent Application No. 918 and the like, a technique using a high molecular weight dimethylpolysiloxane or methylphenylpolysiloxane, or an amino-modified or ammonium-modified high-molecular-weight silicone is provided.

[0006]

[0007] Despite the attempts described above, at present, hair cosmetics that can completely satisfy the needs of consumers have not been provided. . That is, for example, it cannot be denied that silicone oil having excellent characteristics as a compounding component in hair cosmetics has a limit due to its oil content. In other words, it has been generally pointed out that if a large amount of silicone oil is used or if it is used for a long time, the hair becomes sticky or the hair becomes greasy. In addition, cationic surfactants have also been used as a component in hair cosmetics for the purpose of imparting smoothness to hair, but have not yet been able to impart sufficient gloss to hair. Also, it has been pointed out that a large amount of a surfactant is not necessarily preferable in view of safety because it is a surfactant.

Further, even if a natural extract material is used as a base for hair cosmetics, the effect of preventing hair damage cannot be said to be sufficient. For example, in terms of feeling such as smoothness after use,
It was not always satisfactory. Also,
When high molecular weight silicones are used as a component in hair cosmetics, they have some effects in preventing hair damage and imparting gloss and smoothness to hair after use, but have a certain effect, such as brushing and drying. By processing
It has been pointed out that the sustainability of the effect is extremely impaired.

[0008]

Means for Solving the Problems The present inventor has made intensive studies to solve the above-mentioned problems. As a result, certain branched monoesters, certain high molecular weight silicones and / or certain amino- or ammonium-modified high molecular weight silicones and certain linear polysiloxane-

[0014]

Embodiments of the present invention will be described below. The branched monoester of the component (A) contained in the hair cosmetic of the present invention is a branched monoester represented by the general formula (I).

In the formula, the branched alkyl group having 3 to 18 carbon atoms represented by R ¹ and R ² is not particularly limited. For example, isopropyl, isobutyl, isopentyl,
Examples include an isohexyl group, an isoheptyl group, an isooctyl group, an isononyl group, an isodecyl group, an isotridecyl group, an isomyristyl group, an isopalmityl group or an isostearyl group, and particularly preferably an isononyl group or an isotridecyl group.

The branched monoester (I) is, for example,
It can be obtained by an esterification reaction between the above isocarboxylic acid having a branched alkyl group of R ¹ as a carbon chain and, for example, an isoalcohol having a branched alkyl group of R ² as a carbon chain. Such an esterification reaction can be carried out in the absence of a catalyst or in the presence of a catalyst under normal pressure or reduced pressure according to a conventional method. After completion of the esterification reaction, if necessary, the reaction mixture can be decolorized and deodorized and purified by a decolorizing agent and a deodorizing agent, or can be purified by vacuum distillation and the like according to a conventional method.

Incidentally, a commercial product of the branched monoester (I) can be used in the present invention. For example,
Salacos 99 [isononyl isononanoate, manufactured by Nisshin Seimitsu Oil Co., Ltd.], Sarakos 913 [isotridecyl isononanoate, manufactured by Nisshin Seimitsu Oil Co., Ltd.] and the like can be used as commercial products of the branched monoester (I). .

The branched monoester (I) which can be produced in this manner is colorless and odorless, exhibits a liquid state at normal temperature, oxidative stability and acid hydrolysis resistance, regardless of which R ^{1 or} R ² is selected. In addition to having basic properties such as excellent alkali hydrolysis resistance and no irritation to the skin, it has properties of being excellent in compatibility with silicone.

In the hair cosmetic composition of the present invention, the branched monoester (I) may contain one kind alone, or two or more kinds in combination. The blending amount of the branched ester (I) in the hair cosmetic of the present invention can be appropriately selected according to the specific dosage form of the hair cosmetic and the balance with other components.
Generally, 0.01 to 50.0% by weight, preferably 0.1 to 30.0% by weight of the cosmetic is preferred. If the amount is less than 0.01% by weight of the cosmetic, the effect expected in the present invention is not sufficiently exhibited, which is not preferable. Conversely, if the amount exceeds 50.0% by weight, It is not only difficult to expect the improvement of the effect corresponding to the increase in the hair cosmetic, but also the feeling of use of the hair cosmetic tends to be heavy, which is not preferable.

The component (B) contained in the hair cosmetic composition of the present invention comprises, as described above, a high molecular weight silicone represented by the general formula (II) and / or an amino acid represented by the general formula (III). Modified or ammonium-modified high molecular weight silicone.

The molecular weight of the high molecular silicone (II) is about 370,000 to 1.5 million, and it is a soft rubber at room temperature. This high molecular weight silicone (II)
As specific examples of, for example, dimethylpolysiloxane,
Examples include methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, methylphenylpolysiloxane having a terminal hydroxyl group, and dimethylpolysiloxane is particularly preferable.

Commercially available high molecular silicone (II) includes, for example, X-21-7501G (manufactured by Shin-Etsu Chemical Co., Ltd.) and BY11-004 (manufactured by Dow Corning Toray Silicone Co., Ltd.) And the like, and of course, these commercially available products can be used in the present invention.

On the other hand, in the amino- or ammonium-modified high molecular weight silicone represented by the general formula (III), the divalent hydrocarbon group having 3 to 6 carbon atoms represented by R ⁸ includes, for example, propylene Group, tetramethylene group, pentamethylene group, hexamethylene group and the like. Examples of the alkyl group having 1 to 4 carbon atoms represented by R ⁹ and R ¹⁰ include a methyl group, an ethyl group, a propyl group, an isopropyl group, and a butyl group. Examples of the halogen atom represented by A include a chlorine atom, a fluorine atom, an iodine atom, and a bromine atom.

In the amino-modified or ammonium-modified high molecular weight silicone (III), particularly, R ⁵ is a methyl group,
R ⁶ is a methyl group or a hydroxyl group, and R ⁷ is — (CH ₂ ) _{3
NH 2, - (CH 2)} 3 N (CH 3) 2 or - (CH ₂₎
It is preferably a substituent having an amino group or an ammonium group, represented by ₃ N ⁺ (CH ₃ ) ₃ Cl ⁻ .

As described above, in the amino-modified or ammonium-modified high molecular weight silicone (III), m
+ N is 3,000 to 20,000, preferably 40
00 to 20000. When m + n is less than 3000,
Since the amino-modified or ammonium-modified high molecular weight silicone (III) becomes oily, the effect of protecting the hair tends to be insufficient. On the other hand, if it exceeds 20,000, the amino-modified or ammonium-modified silicone (III) is added to other raw materials such as silicone oil. Ammonium-modified high molecular weight silicone (III) is less likely to dissolve, which causes inconvenience in production. N / m is 1
/ 500 to 1/10000, preferably 1/5
00 to 1/2000. If this n / m is more than 1/500, the content of amino groups or ammonium groups in the high molecular weight silicone becomes too high. Is undesirably caused by the side reaction of the compound and the tendency of the product to accompany the raw material odor. On the other hand, when n / m is less than 1/10000, the interaction with the hair by the amino-modified or ammonium-modified high molecular weight silicone (III) becomes insufficient, and the durability of the hair protecting effect of the hair cosmetic of the present invention is maintained. Is not preferable because there is a possibility that a tendency of inferiority is observed.

The amino- or ammonium-modified high molecular weight silicone (III) can be produced by a conventional method. That is, for example, γ-aminopropylmethyldiethoxysilane, cyclic dimethylpolysiloxane, and hexamethyldisiloxane can be produced by a polycondensation reaction under an alkali catalyst, but the production method is limited to this method. Of course it is not.
The amino-modified or ammonium-modified high-molecular-weight silicone (III) is in the form of a soft rubber, and by including it in the hair cosmetic of the present invention, this hair cosmetic can be used in a large amount or even if it is used continuously for a long time. The hair and scalp do not have stickiness and can impart excellent gloss and smooth feel to the hair, and as a result, the protective effect of the hair can be improved.

As the component (B), high molecular weight silicone
(II) and one or more selected from amino-modified or ammonium-modified high molecular weight silicone (III), which are contained in the hair cosmetic of the present invention.
It is more preferable that both of I) and the amino-modified or ammonium-modified high molecular weight silicone (III) are contained in the hair cosmetic of the present invention in combination.

When the high molecular weight silicone (II) and the amino-modified or ammonium-modified high molecular weight silicone (III) are combined and contained in the hair cosmetic composition of the present invention, the stickiness of the hair cosmetic composition is reduced as much as possible. From the viewpoint that it is desirable to remove the feeling of use, the compounding ratio is high molecular weight silicone (II): amino-modified or ammonium-modified high molecular weight silicone (III) = 1: 9
９9: 1 (weight ratio), more preferably, about 2: 8-8: 2. If the mixing ratio of the amino-modified or ammonium-modified high-molecular-weight silicone (III) to the high-molecular-weight silicone (II) is too large, stickiness occurs in the hair cosmetic, and the feeling of use tends to be heavy. There is a tendency that the effect of hair cosmetics on repairing split ends and the effect of bonding to hair are insufficient.

When the above-mentioned component (B) is contained in the hair cosmetic composition of the present invention, it is preferable to dissolve it in the above-mentioned branched monoester (I) as the component (A) before adding it. Instead, for example, the component (A) and the component (B) may be separately compounded in the hair cosmetic composition of the present invention.

The compounding amount of the component (B) can be appropriately selected according to the specific dosage form of the hair cosmetic and the balance with other compounding components. 0.01 to 50.0% by weight, preferably 0.1 to 50.0% by weight.
~ 30.0% by weight is preferred. If the amount is less than 0.01% by weight of the cosmetic, the sufficient effect expected in the hair cosmetic of the present invention is difficult to be obtained, which is not preferable. On the other hand, if the amount exceeds 50.0% by weight, Component (A)
Is not preferred because the solubility in the branched monoester (I) decreases. As described above, the component (C) contained in the hair cosmetic of the present invention is a polysiloxane-oxyalkylene copolymer represented by the general formula (IV).

The polysiloxane-oxyalkylene copolymer (IV) has 2 carbon atoms represented by R ¹¹ and R ^12.
Examples of the divalent hydrocarbon groups of 4 to 4 include an ethylene group, a propylene group, and a tetramethylene group. Also, a and b + c in the above formula are 10 to 10 respectively.
500 and x are preferably 1 to 50.

The compounding amount of the component (C) can be appropriately selected according to the specific dosage form of the hair cosmetic and the balance with other compounding components. 0.01 to 30.0% by weight with respect to
１10.0% by weight is preferred. If the amount is less than 0.01% by weight of the cosmetic, the sufficient effect expected in the hair cosmetic of the present invention is hardly obtained, which is not preferable. On the other hand, if the amount exceeds 30.0% by weight, The feeling of use of the hair cosmetic becomes heavy, and its stability is also unfavorably deteriorated.

The polysiloxane-oxyalkylene copolymer (IV) can be prepared by a conventional method, for example, by preparing a polyoxyalkylene compound having a reactive terminal group and a terminal group which reacts with the reactive terminal group of the polyoxyalkylene compound. It can be produced by reacting a dihydrodihydrocarbylsiloxane having a liquid. As the polysiloxane-oxyalkylene copolymer of the present invention, a commercially available product can be used.For example, it is possible to use a product commercially available under the trade name Silwet F-178 series manufactured by Nippon Unicar Co., Ltd. It is possible.

Thus, the above-mentioned component (A),
The hair cosmetic composition of the present invention containing the component (B) and the component (C) can impart excellent luster to the hair and impart a smooth feel to the hair while adhering and repairing the split ends of the hair. It is. In the hair cosmetic of the present invention, components generally used in hair cosmetics can be blended, if necessary, within a qualitative and quantitative range that does not impair the intended effect of the present invention.

Further, the dosage form of the hair cosmetic of the present invention can be arbitrarily selected, and may be selected from a solubilizing system, an emulsifying system, a powder dispersing system,
