Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hair cosmetic,
More specifically, the present invention relates to a hair cosmetic having good sprayability, a high drying speed on hair, and a high setting power.

[0002]

2. Description of the Related Art Hair cosmetics have been used in the past for adjusting the hairstyle and for prolonging the set hairstyle. This hair cosmetic composition is produced by dissolving, dispersing or emulsifying a hair fixing polymer substance in a suitable solvent such as water, a lower alcohol or a mixed solvent thereof.

[0003] In hair cosmetics containing water, the viscosity of the system increases due to the presence of water, so that there is a problem that the sprayability becomes poor. There is also a problem that the drying speed on the hair becomes slow and the holding power of the set hairstyle is impaired. There is a problem that lowering the water content and increasing the lower alcohol content for lowering the viscosity damages the hair, and in foamy hair cosmetics, the properties of the foam to be ejected are lowered.

In recent years, along with the diversification and individualization of hairstyles, there has been a demand for hard-type hair cosmetics that more firmly set the hair. However, in a hard type hair cosmetic, if a large amount of a polymeric substance is added to set the hair more firmly, the viscosity of the system increases and the polymeric substance remains and sticks in the injection nozzle of the container. There were problems such as easy occurrence of ejection failure such as clogging.

In order to improve these problems, USP3
Japanese Patent No. 972998 proposes a method of reducing the time required for drying hair by applying a hair cosmetic containing a fluoroalkyl (meth) acrylate to the hair. However, although the hair cosmetic containing the polymer disclosed herein has improved “dryness”, it has a problem that the hair setting force is not sufficient when applied to hair as a hair spray or the like. It was

Further, in JP-A-53-121946, there are mentioned fluoroalkyl ethyl methacrylates 60 to 90.
Drying time of hair by treating the hair with a composition comprising a copolymer consisting of 5% by weight, aminoalkylmethacrylate 5 to 25% by weight, and ethylenedimethacrylate or its N-oxide in an amount of about 0 to 10% by weight. A method of shortening is disclosed. However, in this method, since a large amount of the fluoroalkyl group-containing monomer is used, the drying time is shortened, but the hair setting power is still unsatisfactory.

[0007]

In view of the above situation, the present invention is excellent in hair setting force and dryness on hair when applied to hair as a spray type, foam type, or the like. In addition, it is to provide a hair cosmetic having excellent sprayability when applied.

[0008]

Means for Solving the Problems The present invention has been earnestly studied in order to achieve the above-mentioned object, and as a result, a specific fluorine-containing unsaturated monomer and other specific polymerizable monomer are contained in a certain ratio. According to the present invention, it was found that a hair cosmetic having excellent hair setting power and dryness on hair, and excellent jetting property at the time of application can be obtained by using the copolymer obtained by polymerization in Was completed.

That is, the gist of the present invention is (a) a fluorine-containing unsaturated monomer, 5 to 30% by weight, (b) an anionic or amphoteric hydrophilic unsaturated monomer, 15 to 80% by weight,
(C) A hair cosmetic composition containing a copolymer of 30 to 70% by weight of a hydrophobic unsaturated monomer.

As the fluorine atom-containing unsaturated monomer as the component (a), an acrylate or methacrylate containing a fluorine atom (hereinafter, acrylate and methacrylate are collectively referred to as (meth) acrylate) is preferably used. Of these, fluoroalkyl (meth) acrylate represented by the following general formula (1) is particularly preferable.

Such a fluoroalkyl (meth) acrylate can be obtained by reacting a fluoroalkyl compound with (meth) acrylic acid. Instead of fluoroalkyl (meth) acrylate, it is also possible to subject it to copolymerization in the form of its precursor (meth) acrylic acid and then react the fluoroalkyl compound. Examples of the fluoroalkyl (meth) acrylate of the component (a) represented by the general formula (1) include 2,2,2-trifluoroethyl (meth) acrylate and 2,2,3,3, -tetra.

The amount of these fluorine atom-containing unsaturated monomers used is 5 to 30% by weight, preferably 1
It is 0 to 20% by weight. Below 5% by weight, when the resulting copolymer is applied to hair, the drying rate on the hair is slow. If it exceeds 30% by weight, the resulting copolymer becomes poorly soluble in water, and it becomes difficult to wash and remove it during hair washing, and the hair styling effect is deteriorated.

These amphoteric unsaturated monomers can be subjected to copolymerization in the form of a monomer in the same manner as the above-mentioned anionic unsaturated monomer, but as an alternative, they can be used in the form of a precursor. It is also possible to polymerize and then amphoteric with so-called modifying agents.
Further, the salt by-produced by the amphoteric conversion can be removed by filtration, ion exchange or the like, if necessary, at the monomer stage or after the copolymerization stage. Regarding these techniques, Japanese Patent Laid-Open No. Sho 56
This is described in detail in Japanese Patent Publication No. 92809.

The amount of the hydrophilic unsaturated monomer used is 15 to 80% by weight based on the total amount of the monomers. If it is less than 15% by weight, the obtained copolymer becomes poorly soluble in water and / or an ethanol-based solvent, and there is a problem that it is difficult to wash and remove it when washing hair. On the other hand, when it exceeds 80% by weight, the moisture resistance of the obtained copolymer is lowered and the hair setting power under high temperature and high humidity becomes insufficient. A more preferable amount of use is 20 to 60% by weight in the case of an anionic monomer, and about 30 to 70% by weight in the case of an amphoteric monomer.

The hydrophobic unsaturated monomer used as the component (c) is, for example, methyl (meth) acrylate, ethyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl (meth) acrylate or isobutyl (meth) acrylate. ) Acrylate, tertiary butyl (meth) acrylate, cyclohexyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, lauryl (meth)

The amount of the hydrophobic unsaturated monomer used is 30 to 70% by weight, preferably 40 to 60% by weight, based on all the monomers. If the amount used is too small, the hair-setting effect is deteriorated. On the other hand, if the amount used is too large, the finally obtained copolymer becomes poorly soluble in water, which makes it difficult to remove by washing during hair washing, and causes problems such as a decrease in hair styling effect. .

The above-mentioned monomers (a), (b), (c)
Each of these may be used alone, or a mixture of two or more may be used. As the hydrophilic monomer (b), the above-mentioned anionic and amphoteric monomers may be used alone or in combination.

Alternatively, a divided addition method may be used for the amount. The amount of solvent used is such that the polymer concentration in the resulting copolymer solution is 10
The amount is preferably about 65% by weight.

The polymerization temperature and the polymerization time will differ depending on the polymerization method and the grade of the desired product, but usually the polymerization temperature is 50 to 100 ° C. and the polymerization time is about 4 to 20 hours. The weight average molecular weight of the copolymer obtained by the above method is 5,000 to 500,000, preferably 10,000 to 400,000. Control of this molecular weight is controlled by the polymerization temperature, the type and amount of the polymerization initiator,
