Patent Application
20150013712
The present invention relates to a powdery solid composition for hair, a powdery solid hair cosmetic including the composition and a container, a method for producing the cosmetic, and a method for hairdressing using the cosmetic.
Cosmetics for hairdressing are exemplified by liquid, gel, foamy, and mist hair cosmetics containing a film forming resin as a main functional component for hairdressing (for example, see Patent Documents 1 to 4). The cosmetics are also exemplified by cream and wax hair cosmetics containing an oil such as waxes and hydrocarbon oils as a main functional component for hairdressing (for example, see Patent Documents 5 and 6). At the present time, typical hair cosmetics contain a film forming resin or an oil.
The existing hair cosmetics containing a film forming resin or an oil can sufficiently achieve excellent hairdressing function but have a problem of causing sticky feeling and a problem of being difficult to impart a natural texture. In order to solve the problems, various attempts have been made.
There are various methods for hairdressing using hair cosmetics depending on forms of the cosmetics. Typically, a method of hairdressing by using a comb and a method of hairdressing with the palms and fingers of hands have been attempted, for example.
However, the method of hairdressing by using a comb can achieve easy hairdressing of the whole hair but fails to sufficiently achieve hairdressing in fine detail. The method of hairdressing with the palms and fingers in place of a comb can sufficiently achieve hairdressing in fine detail but fails to achieve easy hairdressing.
As described above, conventional hair cosmetics are difficult to easily, sufficiently achieve hairdressing in fine detail. In particular, for example, away from home, it is more difficult to easily, sufficiently achieve hairdressing in fine detail, and easy re-dressing is impossible. In consideration of such hair cosmetics and the circumstances, there is a demand for a hair cosmetic having an unprecedented, novel form and enabling easy hairdressing.

Examples of the container include jar containers and compact containers with a removable lid, jar containers and compact containers with a hinged lid, and stick containers.
In the present invention, a compact container with a removable lid or a compact container with a hinged lid is preferably used because such a container is excellent in convenience and enables easy re-dressing even away from home, for example.
The powdery solid hair cosmetic of the present invention may be either in a state in which the powdery solid composition for hair is directly charged into the container or in a state in which the powdery solid composition for hair is charged into an inner plate installed in the container. The inner plate is preferably, detachably installed in the container. The powdery solid composition for hair may be molded into any shapes, which are designed to fit the shape of a container or an inner plate to be used.
The material of the container used for the cosmetic is not particularly limited and is exemplified by PET resins, AS resins, ABS resins, and polycarbonate resins. The material of the inner plate is also not particularly limited and may be made of either a metal or a resin.
The powdery solid hair cosmetic of the present invention can be produced by a known method. Specific examples of the production method include a production method of compression molding the powdery solid composition (mixture) for hair and a production method of molding the powdery solid composition (mixture) for hair that is not subjected to compression molding by a molding method except the compression molding.
The production method by compression molding may be either a dry method or a wet method. The production method by compression molding is specifically exemplified by a production method that includes a first step of mixing and stirring the powder and the oil to yield a mixture as the powdery solid composition for hair, a second step of directly charging the mixture obtained in the first step into the container or charging the mixture into an inner plate to be installed in the container, and a third step of compression molding the charged mixture.
The mixer used in the first step is not particularly limited, and a mixer capable of homogeneously mixing the powder with the oil is appropriately selected. Examples of the mixer include Henschel mixers, blender mixers, V-mixers, ribbon mixers, Nauter mixers, and high speed mixers.
In the present invention, the mixture obtained in the first step may be charged into the container or the inner plate without treatment. In order to increase the uniformity during charging, the mixture may be pulverized with a pulverizer such as a hammer mill, a pin mill, and an atomizer, then the pulverized product may be passed through a sieve, and the sieved mixture may be charged. In the second step, the mixture may be charged while being vibrated in order to further increase the uniformity during charging.
In the third step, the pressure applied during compression molding is not particularly limited and is appropriately adjusted so as to give a powdery solid having an intended hardness. The pressure applied during compression molding is preferably 0.01 MPa or more, more preferably 0.05 MPa or more, preferably 4 MPa or less, and more preferably 3 MPa or less.
For the compression molding by a dry method, the production method above can be employed. For the compression molding by a wet method, the mixture obtained in the first step is preferably mixed with a volatile solvent into a slurry. Alternatively, the mixture may pulverized with a pulverizer such as a hammer mill, a pin mill, and an atomizer, then the pulverized product may be passed through a sieve, and the sieved mixture may be processed into a slurry.
The volatile solvent used for preparing a slurry may be any solvent capable of making the mixture of the powder and the oil into a slurry. Examples of the volatile solvent include water, ethyl alcohol, isopropyl alcohol, n-butanol, isoparaffin, light isoparaffin, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, octamethyltrisiloxane, tetradecamethylhexasiloxane, and low-viscosity methylpolysiloxane. The volatile solvents may be used singly or in an appropriate combination of two or more of them.
In order to make the mixture into a slurry with the volatile solvent, the volatile solvent is preferably used in an amount of 10 to 150 parts by mass relative to 100 parts by mass of the mixture, and the slurry prepared in the mass ratio is more readily molded into various shapes.
For the compression molding by a wet method, in order to remove the volatile solvent, vacuum aspiration drying is preferably performed during the compression molding, and the molded product is preferably further dried by, for example, air drying, drying by heating, or warm air drying.
The production method without compression molding is exemplified by a production method that includes a first step of mixing and stirring the powder and the oil to yield a mixture as the powdery solid composition for hair, a second step of directly charging the mixture obtained in the first step into the container or charging the mixture into an inner plate to be installed in the container, and a third step of molding the charged mixture that is not subjected to compression molding by a molding method except the compression molding.
Specific examples of the third step without compression molding include a step of molding the mixture by drying, for example, air drying, dried by heating, or warm air drying and a step of molding the mixture by solidification. The solidification of the mixture may be performed by either a method that includes charging the mixture, then warming and dissolving the mixture, and solidifying the mixture or a method that includes warming and dissolving the mixture, then charging the mixture, and solidifying the mixture.
A method for hairdressing using the powdery solid hair cosmetic of the present invention includes a first step of rubbing the surface of the powdery solid composition for hair with a fingertip or an applicator to take the powdery solid composition for hair, a second step of applying the taken powdery solid composition for hair onto hair with the fingertip or the applicator, and a third step of rubbing the powdery solid composition for hair applied onto the hair against the hair with the fingertip or the palm of a hand to perform hairdressing.
The most important feature of the method for hairdressing of the present invention is rubbing the surface of the powdery solid composition for hair to take the composition and performing hairdressing. The means for taking the composition by rubbing is not particularly limited, but the composition is preferably taken by rubbing with fingertips or an applicator. By using the fingertips, the composition can be easily applied to a detailed region, and this enables sufficient hairdressing in fine detail. By using the applicator, the composition can be easily applied to the whole hair, and this enables hairdressing of the whole hair.
The applicator to be used may be any applicator with which the powdery solid composition for hair can be taken by rubbing the surface of the composition. Examples of the applicator include bristle brushes and puffs for powdery solid.
According to the method for hairdressing of the present invention, by rubbing the composition applied to hair against the hair with the fingertips or palms, the hairdressing can be performed into an intended hairstyle. The method for hairdressing above enables easy hairdressing from the whole hair to a detailed region.
The powdery solid composition for hair and the powdery solid hair cosmetic including the composition and a container of the present invention provide an unprecedented, novel form that enables hairdressing into an intended hairstyle without sticky feeling and can impart a natural texture. Therefore, conventional hair cosmetics can be replaced by the composition and the cosmetic.
