2. Description of the Related Art Lingering is an unfavorable habit formed on the hair by physical force under the condition that the amount of water in the hair is large. This is due to hydrogen bonds formed inside the hair,
That is, CO in the keratin molecule, which is a main component of the hair,
It has been found to be a bond between a group and an NH group in an adjacent keratin molecule.

[0003] In order to correct the bedding formed in this manner and fix the hair, it is only necessary to cut off the hydrogen bond in the hair, which causes the hair bond. This hydrogen bond is held down by hand or brushed. It is not possible to cut it just by doing it, and in order to cut it, it is necessary to sufficiently penetrate the hair with water. For this reason, in general, hair straightening is performed by directly applying water to the hair or wrapping it with a hot steamed towel so that the hair is sufficiently moistened, and then drying it with a drier or the like. Have been. However, in this method, a considerable amount of water needs to be applied to the hair in order to completely break the hydrogen bonds formed inside the hair, and therefore, it takes a long time to completely dry the hair. In short, he couldn't easily fix his hair and fix his hair. Also, water applied to the hair may drip and wet the face and clothes.

[0004] In recent years, therefore, a large number of makeup products have been created and marketed, which can be easily used to fix the hair by simply spraying and brushing the hair without using water. I have. For example, JP-A-61-28
No. 2308 discloses a composition containing a cationic surfactant, a polyalkylene glycol ether or a derivative thereof, and a fatty acid alkylolamide at a predetermined ratio.

JP-A-5-163122 discloses a hair cosmetic containing a dimethylpolysiloxane microemulsion obtained by emulsion polymerization, a specific dimethylpolysiloxane polyoxyalkylene copolymer, and water. Is disclosed. Further, Japanese Unexamined Patent Application Publication No. 9-12
No. 4449 discloses that a stock solution containing ethanol, a hair fixing polymer compound and water, and a propellant composed of dimethyl ether are filled in a pressure-resistant container for aerosol spray,
An aerosol spray product in which the injection amount is adjusted to 8 g / 10 seconds or more is disclosed.

[0006]

However, these conventional restorative cosmetics have the following problems. First of all, in the conventional cosmetics for rebalancing,
There is a problem that the hair styling ability for correcting the bedding is not sufficiently satisfactory, and further, the hair styling effect for correcting the bedding is high at high temperatures in summer or the like, but the hair styling effect is significantly reduced at low temperatures in winter or the like. In addition, with these re-dressing cosmetics, the hair becomes squeaky, sticky, and the texture is poor.
There was also a problem that the finish of the hair was inferior.

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems. As a result, a cosmetic for hair containing a dialkyl sulfosuccinate as an essential component has been found to be difficult to penetrate into hair even at low temperatures. The present invention has been found to be excellent in that it can fix undesired habits such as lying down and to fix the hair, and that a smooth and good finish can be obtained without leaving a bad texture such as squeaky or sticky hair. .

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The hair cosmetic composition according to the present invention is characterized in that it contains a dialkyl sulfosuccinate as an essential component. This is because this dialkyl sulfosuccinate can surely penetrate a small amount of water into the inside of the hair, and therefore, even with a small amount of use, it can provide a hair-fixing effect that corrects the bedding, and is also squeaky and sticky. This is because the present inventors have found that a smooth finished feeling can be obtained without leaving a bad texture such as the following. In addition, as a component capable of penetrating water into the inside of the hair, dialkyl sulfosuccinate, perfluoroalkyl polyoxyethylene ethanol, stearyl trimethyl ammonium chloride and the like can be exemplified, and among these, dialkyl sulfosuccinate is Particularly excellent effects can be exhibited.

The dialkyl sulfosuccinate, which is an essential component in the hair cosmetic according to the present invention, has 6 to 2 carbon atoms.
Anionic surfactants obtained by reacting alcohols such as linear or branched alkyl alcohols and hydroxyalkyl alcohols with maleic anhydride to form diesters and then sulfonating them. Examples of alcohols include caprylic alcohol, cetyl alcohol, lauryl alcohol, myristyl alcohol, stearyl alcohol, oleyl alcohol, 2-ethylhexanol, 2-methyldodecanol, 2-methyltridecanol, and the like.

Examples of the neutralizing salt include alkali metals such as lithium, sodium and potassium; alkaline earth metals such as barium, calcium and magnesium; and alkyls such as trimethylamine, triethylamine, tripropylamine, tributylamine and ethyldimethylamine. Examples thereof include alkanolamines such as amine, trimethanolamine, triethanolamine, and tripropanolamine, and it is preferable to use an alkali metal such as sodium.

Particularly, in the cosmetic for hair according to the present invention, it is preferable to use dioctyl sulfosuccinate as the dialkyl sulfosuccinate. This is because dioctyl sulfosuccinate can exert the most excellent effect among various dialkyl sulfosuccinates.

The dioctyl sulfosuccinate is obtained by esterifying maleic anhydride and 2-ethylhexanol to a maleic acid diester and neutralizing the same with acid nitrite, and it is stipulated in "Standards for ingredients of each cosmetic type". It is listed. Examples of commercially available dioctyl sulfosuccinates include NIKKOL OTP-75 (trade name) manufactured by Nikko Chemicals Co., Ltd.

The amount of the dialkyl sulfosuccinate is as follows:
The content is preferably 0.01 to 5% by weight, and more preferably 0.10 to 3% by weight, based on the total amount of the cosmetic for hair. If the amount is less than 0.01% by weight, it is not possible to correct undesired habits such as lying down and to fix the hair, and even if it is more than 5% by weight, no more effect can be expected, This is because any of these cases is not preferable because the texture such as is deteriorated.

In the hair cosmetic composition according to the present invention, the alcohol means ethanol or isopropanol,
In the cosmetic for hair according to the present invention, it can be appropriately added as appropriate. When these alcohols are blended, the blending amount is 30% by weight based on the total amount of the hair cosmetic.
Or less, preferably 20% by weight or less. This is because if the content is more than 30% by weight, the effect of restoring the bed is lowered, which is not preferable.

Further, in the cosmetic for hair according to the present invention, a polyether-modified silicone may be appropriately compounded. This is because by blending the polyether-modified silicone, a good touch can be obtained and a further smooth finished feeling can be obtained. Examples of the polyether-modified silicone include a polyoxyethylene / methylpolysiloxane copolymer and a poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer, but are not particularly limited. Also, one kind or a combination of two or more kinds can be used. When compounding a polyether-modified silicone, the compounding amount is preferably 0.01 to 5% by weight,
More preferably, the content is set to 1% by weight. This is 0.0
If the amount is less than 1% by weight, the effect of the compounding cannot be obtained, and if the amount is more than 5% by weight, no more effect can be expected, and creaking and stickiness are caused. This is because either case is not preferable.

In the hair cosmetic composition according to the present invention, in addition to the above-mentioned components, polyhydric alcohols or sugars and derivatives thereof, water-soluble polymers, oxidized polymers, and the like, as long as the effects of the present invention are not impaired. Inhibitors, UV inhibitors, sequestering agents, thickeners, antibacterial agents, oils, higher fatty acids, fatty acid esters, humectants, fresheners, pigments, surfactants, oily components, preservatives, pH adjusters, fragrances Ordinary cosmetic components such as stabilizers, vitamins and propellants for aerosols, or special compounding components such as animal and plant extract components can be added according to the purpose.

The hair cosmetic according to the present invention can be obtained by uniformly dispersing the above-mentioned components in a conventional manner using water (purified water), and can be used for aerosol sprays, pump formers and pumps. It can be in the form of a spray or the like. The amount of water is about 70 to 99% by weight based on the total amount of the hair cosmetic.
