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, for hair
The present invention relates to an oil-in-alcohol type hair cosmetic capable of bonding and repairing split ends of hair while giving excellent gloss and giving a smooth feel.

[0002]

2. Description of the Related Art Hair is roughly divided into "protective roles".
And "role of beauty".

The former "protective role" is, literally, a role of protecting the body, protecting our head from direct sunlight, heat and cold, and buffering against external shocks. Demonstrate. Also, the latter "role of beauty" is the role of hair that impresses a person, and it is very common that the same person can be captured as a person with a completely different impression depending on the type of hair. It is a fact.

[0004] Despite this important role, hair is constantly exposed to various external stresses. In other words, in addition to the original stress factors due to the sun's ultraviolet rays and dirt, the hair is subjected to more severe stress due to hair washing, brushing, heat by a dryer, hair coloring, beauty treatment with a bleaching agent, etc. It is well known that the hair is dry, causes split ends, cuts, loss of hair, and the like, and causes a decrease in the strength of the hair.

[0005] Therefore, various attempts have been made from various angles to prevent and improve the above-mentioned hair damage. As one of such attempts, oils such as silicone oil, ester oil, and hydrocarbon oil have been used for the purpose of imparting gloss and smoothness to hair. In particular, silicone oils
In recent years, it has been frequently used because of its low surface tension, excellent adaptability to hair, and good gloss.

[0006] However, this silicone oil also has a limitation in blending which is peculiar to the oil component.
It was recognized that the hair would become greasy if used continuously for a long time.

Also, for the purpose of imparting smoothness to hair,
Cationic surfactants are also widely used, but this does not necessarily mean that a sufficiently satisfactory gloss is imparted to the hair, and furthermore, if a large amount of this is blended, it is not preferable in terms of safety. There were drawbacks.

For the purpose of protecting and repairing hair, various materials extracted from natural products, such as proteins, polysaccharides, extracted extracts or natural macromolecules, or a simple substance or a component thereof, are used as bases for the purpose of protecting and repairing hair. Oligomers (for example,
Hair cosmetics containing amino acids, peptides, etc.).

[0009] However, 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, and for example, the feeling of smoothness after use can be sufficiently satisfied. It was not something.

Further, in order to prevent the hair from being damaged while imparting gloss and smoothness to the hair, Japanese Patent Application Laid-Open No. 63-183
No. 17, JP-A-63-24301, JP-A-6-24301
As described in JP-A-3-313712, JP-A-5-85918, etc., a technique using a high-molecular-weight dimethylpolysiloxane, a methylphenylpolysiloxane, or an amine-modified or ammonium-modified high-molecular-weight silicone, or Hair cosmetics using a combination of a polysiloxane-oxyalkylene copolymer and a silicone derivative have been provided.

[0011] However, even if such high molecular weight silicones are used, it is hard to say that they are perfect in terms of the gloss imparting effect on hair and the effect of repairing split ends.

[0012]

Accordingly, there has been a need to develop a hair cosmetic which is capable of bonding and repairing split ends of hair while providing excellent gloss and smooth feel to damaged hair. Was desired.

[0013]

Examples include an isopalmityl group or an isostearyl group,
Particularly, it is 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-mentioned isocarboxylic acid having a branched alkyl group of R ¹ as a carbon chain and isoalcohol having a branched alkyl group of R ² as a carbon chain. This esterification reaction can be carried out in the absence of a catalyst or in the presence of a catalyst at normal pressure or reduced pressure according to a conventional method. After the esterification reaction, if necessary, the reaction mixture can be decolorized and deodorized with a decolorizing agent or a deodorizing agent, or can be purified by vacuum distillation or the like according to a conventional method.

It is also possible to use a commercially available product of the branched monoester (I) in the hair cosmetic of the present invention. Examples of commercially available branched monoesters (I) include Salakos 99 (isononyl isononanoate, manufactured by Nisshin Oil Co., Ltd.) and Sarakos 913 (isotridecyl isononanoate,
Nisshin Oil Co., Ltd.).

This branched monoester (I) is tasteless and odorless, exhibits a liquid state at room temperature, and has oxidation stability, acid hydrolysis resistance and alkali hydrolysis resistance regardless of which R ^{1 or} R ² is selected. In addition to having the basic properties that no irritation to the skin is observed, it has the property of being excellent in compatibility with silicone.

In the hair cosmetic composition of the present invention, only one type of the branched monoester (I) may be used, or two or more types may be used in combination. The blending amount of the branched monoester (I) as the component (A) in the hair cosmetic of the present invention can be appropriately selected depending on the specific form of the hair cosmetic and the balance with other components. However, generally, 0.01 to 3 of the whole hair cosmetics
It is preferably 0.0% by weight, and particularly preferably 0.1 to 20.0% by weight. This amount is 0.1% of the total hair cosmetic composition.
When the amount is less than 01% by weight, the effect that the hair cosmetic of the present invention should exhibit is not sufficiently exhibited, which is not preferable.
If the amount exceeds 0.0% by weight, not only the effect corresponding to the increase in the blending amount cannot be substantially improved, but also the use feeling of the hair cosmetic tends to become heavy, which is not preferable.

The component (B) blended in the hair cosmetic composition of the present invention comprises a high-molecular-weight silicone represented by the general formula (II) and / or an amino- or ammonium-modified silicone represented by the general formula (III) High molecular weight silicone.

The high molecular weight silicone (II) has a molecular weight of about 370,000 to 1,500,000, and is a soft rubber at room temperature. Specific examples of the high molecular weight silicone (II) include, for example, dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, and methylphenylpolysiloxane having a terminal hydroxyl group. Particularly, dimethylpolysiloxane is preferable. .

Commercially available high molecular weight silicones (II) include, 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 cosmetic of the present invention.

On the other hand, in the amino-modified or ammonium-modified high molecular weight silicone represented by the general formula (III), the alkylene group having 3 to 6 carbon atoms represented by R ⁸ includes, for example, a propylene group, Examples include a methylene group, a pentamethylene group, and a hexamethylene group. 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. Also,
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 N
_{H 2, - (CH 2)} 3 N (CH 3) 2 or - (CH _{2) 3} N ⁺
It is preferably (CH ₃ ) ₃ Cl ⁻ .

In the amino-modified or ammonium-modified high molecular weight silicone (III), as described above, m +
n is 3,000 to 20,000, preferably 400
0 to 20,000. If m + n is less than 3000, the amino- or ammonium-modified high molecular weight silicone (II
Since I) becomes oily, the hair protecting effect tends to be insufficient, which is not preferable. On the other hand, if it exceeds 20,000, the amino-modified or ammonium-modified high molecular weight silicone (III ) Is difficult to dissolve, and the production of hair cosmetics tends to be difficult, which is not preferred.

Further, n / m is 1/500 to 1/100.
00, preferably 1/500 to 1/2000. When this n / m exceeds 1/500, the content of amino groups or ammonium groups in the high-molecular-weight silicone (III) becomes high, and as a result, crosslinking during the production of the amino- or ammonium-modified high-molecular-weight silicone (III) occurs. It is not preferable because side reactions such as a reaction occur, and a product tends to be accompanied by a raw material odor. On the other hand, n / m is 1/100
If it is less than 00, the interaction between the amino-modified or ammonium-modified high molecular weight silicone (III) and the hair becomes insufficient, and the desired persistence of the hair protection effect tends to be deteriorated, which is not preferable.

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. Not something. The amino-modified or ammonium-modified high molecular weight silicone (III) is in the form of a soft rubber, and the hair or cosmetic composition of the present invention containing the same may cause sticky hair or scalp even if used in a large amount or continuously for a long time. Instead, it is possible to impart excellent gloss and smooth feel to the hair, and as a result, it is possible to improve the protective effect of the hair.

As the component (B), one or more kinds are selected from high molecular weight silicone (II) and amino-modified and ammonium-modified high molecular weight silicone (III),
Although it is blended in the hair cosmetic of the present invention, it is more preferable that both the high molecular weight silicone (II) and the amino-modified or ammonium-modified high molecular weight silicone (III) are combined in the hair cosmetic of the present invention.

When the high-molecular-weight silicone (II) is combined with the amino-modified or ammonium-modified high-molecular-weight silicone (III) in the hair cosmetic of the present invention, the tackiness of the hair cosmetic is reduced as much as possible. In view of eliminating the feeling of use, the compounding ratio is about 1: 9 to 9: 1 (weight ratio) of high molecular weight silicone (II): amino-modified or ammonium-modified high molecular weight silicone (III). It is particularly preferable that the ratio be about 2: 8 to 8: 2.

If the proportion of the amino-modified or ammonium-modified high-molecular-weight silicone (III) to the high-molecular-weight silicone (II) is too large, the hair cosmetic will be sticky,
The feeling of use tends to be heavy, which is not preferable. On the other hand, if the amount is too small, the effect of restoring split ends and the effect of bonding to hair with the hair cosmetics tend to be insufficient, which is not preferable.

The amount of the component (B) in the hair cosmetic can be appropriately selected according to the specific form of the hair cosmetic and the balance with other components. The amount is preferably 0.01 to 50.0% by weight, and particularly preferably 0.1 to 30.0% by weight, based on the total weight of the hair cosmetic. If the amount is less than 0.01% by weight of the total hair cosmetic composition, the effect of the hair cosmetic composition of the present invention is not sufficiently exhibited, which is not preferable. On the other hand, if it exceeds 50.0% by weight, It is difficult to dissolve in hair cosmetics, which is not preferable.

In the hair cosmetic composition of the present invention, it is preferable that the component (B) is dissolved in the branched monoester (I) as the component (A) and then blended. However, the present invention is not limited thereto. In some cases, the component (A) and the component (B) are separately blended with the hair cosmetic composition of the present invention, and the component (B) is dissolved in the composition. You can also.

The type of the lower alcohol, which is the component (C), to be incorporated in the hair cosmetic composition of the present invention is not particularly limited, but ethanol is preferred in view of safety and the like. It should be noted that i-propanol, n-propanol, t-butanol, s-butanol, etc. are too strong in hydrophobicity and are difficult to emulsify.

In the hair cosmetic composition of the present invention, (C)
The amount of the lower alcohol as a component can be appropriately selected depending on the form of the specific hair cosmetic or the balance with other components, but generally, the amount of the lower alcohol is The amount of water as the component (D) in the hair cosmetic is preferably three times or more (weight ratio), and the blending amount of the lower alcohol is 50% of the total amount of the hair cosmetic.
It is preferred that the content be at least 10% by weight.

When the amount of the lower alcohol is less than three times the amount of water, the emulsifier polyether-modified silicone (IV)
This causes gelation of the entire system, increases the viscosity, and makes the hair cosmetic composition difficult to emulsify, which is not preferable.

If the amount of the lower alcohol is less than 50% by weight of the hair cosmetic, it is difficult to obtain a stable oil-in-alcohol emulsion composition, which is not preferable. The amount of water as the component (D) in the hair cosmetic of the present invention is preferably from 0.01 to 10.0% by weight of the entire hair cosmetic. The amount of water is 0.1% of the total amount of the hair cosmetic.
If the amount is less than 01% by weight, the stability of the obtained oil-in-alcohol type emulsion composition tends to be poor. Tends to be undesirable.

The polyether-modified silicone as the component (E) to be incorporated in the hair cosmetic composition of the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the above general formula (IV). 5-3111076
The emulsifier is described in Japanese Patent Application Laid-Open (JP-A) No. 6-208131.

In the polyoxyalkylene group in the general formula (IV), examples of the acyl group of R ′ include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group, a benzoyl group and a toluoyl group. And specific examples of the alkyl group having 1 to 4 carbon atoms include a methyl group, an ethyl group, an i-propyl group, an n-propyl group, a t-butyl group, and an n-butyl group. .

Further, polyether-modified silicone (IV)
In the polyoxyalkylene group in the above, a and b are 5 to
50. When a or b is less than 5, the polyether-modified silicone does not show a sufficient surface active effect, which is not preferable. On the other hand, when a or b exceeds 50, the obtained hair cosmetic is sticky. A feeling is accompanied, which is not preferable.

Further, polyether-modified silicone (IV)
In the above, the content of the polyoxyalkylene group in one molecule is not particularly limited, but the content of the polyoxyalkylene group desirably exceeds 20% by weight of the total molecular weight. This is because when the content of the polyoxyalkylene group is 20% by weight or less of the total molecular weight, the thickening effect of the polyether-modified silicone (IV) is significantly reduced.

X is an integer of 50 to 1000;
y is an integer of 1 to 40, preferably x is 200 to
600, y is 5-20. x is less than 50 or y is 1
If the amount is less than 1, the emulsion stability of the obtained hair cosmetic is deteriorated, which is not preferable. On the other hand, if x exceeds 1000 or y exceeds 40, the obtained hair cosmetic has a sticky feeling. It is not preferred.

The molecular weight of the polyether-modified silicone (IV) used in the hair cosmetic of the present invention is not particularly limited, and its viscosity at 25 ° C. is not particularly limited, but it forms a particularly stable emulsion and gives a smooth feeling. In order to obtain a hair cosmetic having the above, the polyether-modified silicone (IV) used in the hair cosmetic of the present invention has a viscosity of 1,000 to 100,000 mPa · s in a 50% by weight solution of octamethyltetrasiloxane or isoparaffin. It is preferred that they are in the range. The molecular weight is 50,000 or more from the viewpoint of stability and usability,
Preferably, it is in the range of 50,000 to 80,000.

In the hair cosmetic composition of the present invention, only one polyether-modified silicone (IV) may be used, or two or more polyether-modified silicones (IV) may be used in combination.
In the hair cosmetic composition of the present invention, the amount of the polyether-modified silicone (IV) as the component (E) is appropriately selected depending on the specific form of the hair cosmetic composition and the balance with other components. In general, the amount is preferably 1.0 to 30.0% by weight, and particularly preferably 3.0 to 20.0% by weight based on the total amount of the hair cosmetic. If the amount of the polyether-modified silicone (IV) is less than 1.0% by weight of the total hair cosmetic composition, stable emulsification of the hair cosmetic composition becomes difficult, which is not preferable. If it exceeds, the hair cosmetics will have a sticky feeling,
Not preferred.

The hair cosmetic of the present invention includes the above (A) to
(E) In addition to the component, a quantitative amount that does not impair the effects of the present invention
In the qualitative range, if necessary, polyhydric alcohols, anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric surfactants, anionic polymers, cationic high Drugs such as molecules, non-ionic polymers, polysaccharides, chelating agents, antioxidants, ultraviolet absorbers, preservatives, vitamins, etc.
Components generally used for hair cosmetics, such as fragrances, can be blended.
