Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling composition in the form of a foam aerosol or a liquid, which can be used for styling hair and can maintain a good feeling of use, particularly a soft and smooth finish.

[0002]

2. Description of the Related Art Conventionally, it has been widely used in various hair styling products containing compounds such as silicone oil, oils, polyols, surfactants and proteins for the purpose of imparting a finished feeling during hair styling. For example, Japanese Patent Application Laid-Open No. 63-126811 discloses a cosmetic composition containing 3-methyl-1,3-butanediol with improved feeling of use and viscosity.
JP-A-116121 discloses a hair detergent composition containing 3-methyl-1,3-butanediol and a nitrogen-containing water-soluble polymer, which has improved moist feeling, suppleness, luster and combability. Further, JP-A-2-11506 discloses a foam-forming aerosol type hair cosmetic containing a high-molecular-weight dimethylpolysiloxane, a cationic polymer, and an anionic surfactant. Furthermore, the present applicant has previously proposed a hair cosmetic composition containing a specific diol such as 2-methyl-2,4-pentanediol and an additive such as a cationic polymer compound. However, when the hair is treated with these conventional cosmetics, the finish feel is not sticky and smooth, the selectivity is imparted but the soft feel is not achieved, and after treatment, a sufficient effect is obtained over time. There is a problem such as not holding.

DISCLOSURE OF THE INVENTION The present invention overcomes the drawbacks of the conventional hair styling composition and provides a soft and smooth feel with a long-lasting effect of providing a foam aerosol formulation or liquid form. An object of the present invention is to provide a hair styling composition.

[0004]

The present inventors have conducted various studies to develop a hair styling product having the above-mentioned preferable properties, and as a result, used a specific high molecular weight dimethylpolysiloxane and a specific glycol in combination. By
The present invention has been completed by finding that a hair styling product that gives a soft and smooth touch to hair and is excellent in the durability of its effect was completed. That is, according to the present invention, 2
A high-molecular-weight dimethylpolysiloxane having a viscosity of at least 30,000 centistokes at 5 ° C., 3-methyl-1,3-butanediol and / or 2-methyl-2,
There is provided a hair styling composition characterized by being blended with 4-pentanediol. Hereinafter, the present invention will be described in more detail.

The high-molecular-weight dimethylpolysiloxane, which is the active ingredient of the hair styling composition of the present invention, has the following formula (1):

Embedded image (In the formula, n represents the degree of polymerization.) Among dimethylpolysiloxanes represented by the formula, the viscosity at 25 ° C. is 30,000.
It is a high molecular weight dimethylpolysiloxane having a centistokes or more, preferably 100,000 centistokes or more. If the viscosity of dimethylpolysiloxane is less than 30,000 centistokes, the hair will have sufficient softness,
A smooth finish cannot be imparted, and a satisfactory sustainability of the effect cannot be obtained. Further, in the present invention, the above-mentioned high molecular weight dimethylpolysiloxane can be used alone or in combination of two or more kinds, and the blending amount thereof is 0.01 to 30% of the entire hairdressing preparation.
(% By weight, the same applies hereinafter), preferably in the range of 0.1 to 20%. If the blending amount is less than 0.01%, the effect of imparting a soft and smooth touch to the hair and maintaining it may be insufficient, and if it exceeds 30%, the hair may be heavyly finished. In the liquid hair styling product of the present invention, it is convenient in terms of production to add an emulsion of high molecular weight dimethylpolysiloxane in advance, and it is preferable in terms of product stability.

Further, in the present invention, a low-viscosity polysiloxane such as polyalkyl siloxane, polyaryl siloxane or polyaryl siloxane may be used together with the above high molecular weight dimethyl polysiloxane.

The glycols used in the present invention are 3-methyl-1,3-butanediol and 2-methyl-2,4-pentanediol (hexylene glycol), which may be used alone or You may use it in combination of 2 types. The content of these glycols is usually 0.1 to 50%, preferably 0.5 to 40, based on the total amount of the hair styling product.
%, More preferably 1 to 30%. If this amount is less than 0.1%, the initial effect is not sufficiently exhibited, and if it exceeds 50%, stickiness occurs.

In addition to the above-mentioned essential components, the hair styling composition of the present invention may contain various additives conventionally used in hair styling compositions, as long as they do not impair the object of the present invention. Various such additives are listed below.・ Anionic surfactant ・ Ampholytic surfactant ・ Cationic surfactant such as stearyltrimethylammonium chloride, distearyldimethylammonium chloride, stearyldimethylbenzylammonium chloride ・ Stearic acid diethanolamide, coconut oil fatty acid diethanolamide, POE curing castor Oil, nonionic surfactant such as POE stearyl ether, etc.-Cationized cellulose (ether of hydroxyethyl cellulose and glycidyl trimethyl ammonium chloride), cationic polymer compound such as quaternized product of dimethylaminoethyl methacrylic acid copolymer-Polyvinyl Nonionic polymer compounds such as pyrrolidone, vinylpyrrolidone vinyl acetate copolymers, amphoteric acrylic polymers, propylene glycol, glycerin, polyethylene glycol Alcohol compounds such as alcohol ・ Fatty acids, natural oils and fats, higher alcohols, hydrocarbons, ester oils ・ Sterilizing and preservatives such as paraben and triclosan ・ Solvents such as ethanol and isopropanol Colorants, pigments, fragrances, UV absorbers, etc. Can be mentioned.

In the case of the foam-forming aerosol type, the hair styling composition of the present invention contains a propellant. Liquefied petroleum gas, nitrogen gas or the like can be used as the propellant. It is prepared and used in the same manner as in ordinary aerosol type cosmetics, in which the active ingredient and the oil-soluble ingredient are separately dissolved and mixed, and in some cases they are further mixed, and these and the propellant are filled together in a closed container. can do. In the case of a liquid composition, among the above-mentioned components, a water-soluble component and an oil-soluble component can be separately dissolved and mixed, and these can be mixed and filled in a container for use.
