Problems to be solved by the invention

However, when a powdery or solid hair cosmetic is dissolved in water to form a solution having a viscosity, it is necessary to contain a component for increasing the viscosity in the hair cosmetic, but if a large amount of the viscosity component is contained, the dissolution in water tends to be difficult.

In addition, when a solution having a viscosity is formed by dissolving not only a hair cosmetic material in water, if a large amount of a viscosity component is contained in a powder or a solid, it is difficult to dissolve the hair cosmetic material in water, and there is a possibility that dissolution residue may occur to deteriorate the quality.

In recent years, it has been desired to obtain a cosmetic having the functions of these components by dissolving a powdery or solid substance in a liquid composition having a certain viscosity such as a cosmetic.

Detailed Description

Embodiments of the cosmetic according to the present invention are described in detail below.

The cosmetic material described in the embodiment is merely an example for explaining the cosmetic material according to the present invention, and is not limited thereto.

In the embodiments, hair cosmetics including hair care agents such as shampoo, conditioner, hair styling agent, hair tonic, and hair dye will be described as examples. In addition to hair cosmetics, cosmetics include facial care agents such as lotions, emulsions, lip balms, sunscreens, face washes, cleansing lotions, shaving foams, cleansing oils, and body care agents such as soaps, body washes, hand creams, hand washes, antiperspirants, and bathing agents.

Specifically, the present invention can impart the functions of the components of a solid composition to a liquid composition (cosmetic) by dissolving the solid composition in a cosmetic having a viscosity of 200 mPas or more at 25 ℃. For example, a color shampoo composition or color care composition can be made by using the shampoo composition or care composition as a liquid composition, dissolving a solid composition containing the direct dye and a specific excipient. Shampoo refers to a composition containing a surfactant for cleaning, and care refers to a composition containing a component for improving hair feel.

In this case, the solid composition in the form of a powder or a solid formed by compression molding of a powder can be easily dissolved in a liquid composition having a viscosity of 200 mPas or more at 25 ℃.

(Hair cosmetic)

The hair cosmetic composition of the present invention comprises a liquid composition having a viscosity of 200 mPas or more at 25 ℃ and a solid composition in the form of powder or a solid formed by compression molding of the powder, and is applied to hair by dissolving the solid composition in the liquid composition to prepare a solution. By dissolving the solid composition in a liquid composition having a viscosity, the content of a component (a viscosity increasing component) for increasing the viscosity of the solid composition can be reduced or eliminated, and the effect of easy dissolution can be obtained.

(liquid composition)

The liquid composition of the present invention is not particularly limited as long as it has a viscosity of 200mpa·s or more, and for example, the viscosity is 200mpa·s or more and 50000mpa·s or less. The lower limit value is preferably 1000 mPas, more preferably 3000 mPas, and even more preferably 5000 mPas. On the other hand, the upper limit value is preferably 40000mpa·s, more preferably 30000mpa·s, and even more preferably 20000mpa·s.

In the above viscosity range, the solid composition is more easily dissolved, and the viscosity of the dissolved solution is easily spread on the hair as a hair cosmetic, and a uniform and preferable state is obtained in which dripping is not easily caused.

The liquid composition may be 200 mPas or more, and commercially available shampoo compositions and care compositions may be used.

For example, shampoo compositions used as liquid compositions may be exemplified in which a surfactant is used as a main component, and in which an oily component, hydrocarbon, cationic compound, polymer, protein hydrolysate, pH-buffering component, saccharide, amino acid, vitamin, ceramide, chelating agent, perfume, and the like are added from the viewpoints of improvement of detergency, storage stability, good feel in use, and the like, a cationic surfactant is preferable as a surfactant to be blended as a main component.

When the surfactant is a cationic surfactant, it is more preferably 1 or 2 or more of sulfate-type, phosphate-type, sulfonate-type, and carboxylate-type anionic surfactants, and among these, carboxylate-type anionic surfactants are more preferred.

In addition, the content of the cationic surfactant used as the shampoo composition of the liquid composition may be suitably 0.1% by mass or more and 30% by mass or less. The lower limit is more preferably 0.5 mass% or more, and still more preferably 1.0 mass% or more. On the other hand, the upper limit is more preferably 25.0 mass% or less, and still more preferably 20.0 mass% or less.

Further, as the liquid composition, a composition containing a surfactant as a main component, and further containing an oily component, hydrocarbon, cationic compound, polymer, protein hydrolysate, pH buffer component, saccharide, amino acid, vitamin, ceramide, chelating agent, perfume, etc. as a main component, a cationic surfactant is preferable from the viewpoints of excellent feeling in use, smoothness in finger combing during drying, and hair end drying alleviation.

When the surfactant is a cationic surfactant, a monoalkyl (C10-C22) trimethylammonium salt type cationic surfactant, a dialkyl (C10-C22) dimethylammonium salt type cationic surfactant, an amidoammonium salt type (quaternary ammonium salt-33 or the like) cationic surfactant, an etherammonium salt type cationic surfactant, an esterammonium salt type cationic surfactant, a neutral ammonium salt type cationic surfactant or the like can be exemplified, and among these, 1 or 2 or more kinds of cationic surfactants are more preferable, and among these, a carboxylate type anionic surfactant is further preferable.

Further, the nonionic surfactant is more preferably contained, and among the nonionic surfactants, 1 or 2 or more kinds of surfactants having an HLB value of 4 or more and less than 10 and surfactants having an HLB value of 10 or more and less than 20 are more preferably contained.

Further, it is more preferable that the cationic surfactant and the nonionic surfactant are contained in an amount of 1 or 2 or more.

In addition, the content of the cationic surfactant used as the care composition of the liquid composition may be suitably 0.1% by mass or more and 30% by mass or less. The lower limit is more preferably 0.5 mass% or more, and still more preferably 1.0 mass% or more. On the other hand, the upper limit is more preferably 25.0 mass% or less, and still more preferably 20.0 mass% or less.

The viscosity of the liquid composition can be determined, for example, using a type B viscometer under measurement conditions of 25 ℃ and 1 minute. Specific examples of the type B VISCOMETER include a BL VISCOMETER viscolter (manufactured by eastern machine industry company). The rotor and the rotational speed used may be appropriately selected according to the range of the measurable viscosity of the measuring apparatus. For example, a rotor No. 1 may be used when the viscosity is 100 to 250 mPas, a rotor No. 2 may be used when the viscosity is 250 to 2500 mPas, a rotor No. 3 may be used when the viscosity is 2500 to 10000 mPas or more, and a rotor No. 4 may be used when the viscosity is 10000 mPas or more, all of which are obtained at a rotation speed of 12 rpm.

Hereinafter, the viscosity in this specification is a value measured at 25 ℃.

The liquid composition may be a commercially available shampoo composition or care composition which is obtained by a user when using the solid composition, or may be a single commercial product obtained by combining the solid composition and the liquid composition.

When the user uses the liquid composition obtained by himself/herself, it is not necessary to circulate the liquid composition, and it is preferable from the viewpoint of reducing the transportation cost of the hair cosmetic product. In addition, the liquid composition can be used by the user according to the preference of the user.

In addition, when the solid composition and the liquid composition are combined into a single commodity stream for market, the liquid composition which is difficult to obtain or the liquid composition for preparing the solid composition can be sent to the user together, and the convenience of the user can be improved.

(solid composition)

The solid composition includes a powder form or a solid form formed by compression molding of a powder. The shape of the solid composition of the powder is not particularly limited, and examples thereof include spheres. The particle size of the powder is not particularly limited, and for example, a powder having an average particle size of 100 to 500 μm or 32 to 150 mesh (JIS Z8801-1:2006) is preferable in terms of mixing property, fluidity and solubility at the time of mixing the raw materials. The shape of the solid composition in the form of a solid formed by compression molding of a powder is not particularly limited, and examples thereof include a disk shape, a columnar shape, a prismatic shape, and a spherical shape. The convenience of transportation and consumers can be improved by compacting the powder into a solid form.

The method for producing the solid composition of the present invention is not particularly limited, and can be produced by a known method. For example, in the form of powder, the composition can be produced by mixing the components. In the case of solid form, the composition can be produced by directly tabletting the mixed components and additives, or by tabletting the granulated components and additives after mixing. In addition, a disk granulator or a drum granulator may be used to produce granular particles. In addition, the sheet may be formed by compression molding using a compression molding machine such as a roller compactor. From the viewpoint of improving the strength and productivity of the solid composition, the solid composition molded by compression molding of the powder is preferably a compressed tablet (compression molded body) formed by compression molding.

When the powder is compressed and molded into a solid form, the powder may be contained in a state where the powder is not pulverized (liquid or gel-like) as long as the powder can be compressed and molded, but preferably not contained, so that a compressed and molded product can be easily produced.

When the hair cosmetic of the present invention is used as a hair cosmetic, the solid composition is dissolved in a liquid composition having a viscosity of 200mpa·s or more, and therefore, the viscosity component can be reduced or not contained in the solid composition, and a solid composition which is easily dissolved can be obtained.

In other words, when the solid composition is dissolved in a solvent such as water having a low viscosity to prepare a hair cosmetic having the same viscosity as the hair cosmetic of the present invention, the content of the viscosity component of the solid composition needs to be higher than that of the solid composition of the present invention. However, when a large amount of the viscosity component is contained, there is a problem that it is difficult to uniformly dissolve. In the present invention, by dissolving the solid composition in advance in a liquid composition having a viscosity of 200mpa·s or more, the viscosity increasing component of the solid composition can be reduced or contained, and thus the dissolution is easy.

In addition, from the viewpoint of the solubility of the solid composition in the liquid composition, the powder is more preferable than the solid composition molded by compression molding the powder. From the viewpoint of time-consuming powdering, it is more preferable to form a substance that is solid at ordinary temperature into fine particles than to form a powder by powdering.

The shape of the compression-molded body is not particularly limited, and examples thereof include a circular sheet, an elliptical sheet, a flower-shaped sheet, and the like. In addition, the compression-molded body may be provided with 1 or more dividing lines for dividing into two, four, or the like as needed.

The size (diameter) of the compression-molded body is not particularly limited, and is, for example, 5mm to 50mm in diameter. The lower limit is more preferably 10mm, still more preferably 12mm, and particularly preferably 14mm. On the other hand, the upper limit value is more preferably 30mm, still more preferably 18mm, and particularly preferably 16mm.

In the present specification, the diameter of the compression-molded body in the disk-like shape is the distance between line segments connecting points where a line passing through the center of a circle and a circumference intersect, and the diameter of the compression-molded body in other shapes is the diameter of the longest portion of the compression-molded body.

The thickness of the compression-molded body is not particularly limited, and is, for example, 1.0mm or more and 20.0mm or less. The lower limit is more preferably 2.0mm, still more preferably 2.5mm, and particularly preferably 3.0mm. On the other hand, the upper limit value is more preferably 15.0mm, still more preferably 12.0mm, and particularly preferably 10.0mm.

By setting the size and thickness of the solid composition to the above ranges, the amount of the solid composition can be easily adjusted for use in hair, and excessive use can be prevented, and the solid composition can be easily added for use in hair.

In addition, by setting the size of the solid composition to 20.0mm or more, it is possible to prevent the infants, the elderly, and the like from eating by mistake.

The hardness of the compression molded body before water is not particularly limited as long as the compression molded body can be maintained in the form of a solid, and for example, the hardness is 0.001kgf or more and 10.0kgf or less under the conditions of 25 ℃ and a humidity of 75%. The lower limit value is more preferably 0.005kgf, and still more preferably 0.01kgf. On the other hand, the upper limit value is more preferably 8.0kgf, still more preferably 5.0kgf, and still more preferably 3.0kgf.

The hardness of the fixing composition obtained by compression molding after immersing in water (25 ℃) for 3 seconds is not particularly limited, and for example, the hardness is 0.0kgf or more and 3.0kgf or less. The lower limit value is more preferably 0.5kgf, and still more preferably kgf. On the other hand, the upper limit value is more preferably 1.0kgf, still more preferably 0.5kgf, and still more preferably 0.1kgf.

The hardness of 0.0kgf means a state in which the compression molded body disintegrates in the liquid composition.

The hardness was measured using a tablet durometer simulation TH-1 manufactured by AS ONE CORPORATION, and the minimum measurement value was 0.1kgf.

By setting the hardness of the compression-molded body to the above range, the following effects are obtained: the present invention is advantageous from the viewpoint of easy disintegration of the compression-molded article when immersed in the liquid composition and pressurized at the time of use, such as transportation and storage before containing the liquid composition.

Next, a method for producing the compression molded body will be described.

The method for producing the compression molded article can be carried out by a usual method used in the technical fields such as cosmetics, pharmaceutical products and pharmaceuticals. As a process for producing the compression molded body, the components and additives after mixing may be directly compressed into tablets, or the components and additives after granulating may be mixed and compressed into tablets.

The granulation method is not particularly limited, and examples thereof include a dry granulation method, a fluidized bed granulation method, a roller granulation method, a stirring granulation method, a spray granulation method, and the like.

The mixer used in the mixing step is not particularly limited, and examples thereof include a tumbler mixer, a V-type mixer, a twin cone mixer, and an infinite mixer.

The tablet press used in the tabletting step is not particularly limited, and examples thereof include a single-shot tablet press and a rotary tablet press.

Next, a method of using the hair cosmetic of the present invention will be described.

The solid composition is used as a hair cosmetic after being dissolved by adding a liquid composition having a viscosity of 200mpa·s or more to the hair before being used for the hair and the like. For example, the solid composition is placed on one hand, an appropriate amount of the liquid composition is added thereto, and the solid composition is dissolved with the other hand, and then used. Whereby the solid composition can be quickly dissolved in the liquid composition.

In addition, for the compression molded body, a hair cosmetic may be added to the compression molded body, and then pressure may be applied by hand. The compression molded body is broken or deformed by applying pressure, so that the surface area can be increased to be rapidly dissolved.

The hair cosmetic composition of the present invention may be used as a hair cosmetic kit in combination with a container for dissolving the solid composition, for example. This is excellent in portability, and by providing a container, dissolution in a liquid composition can be easily performed.

In addition, the container is preferably provided with a metering line for metering the amount of the liquid composition for the solid composition. By metering the amount of liquid composition used for dissolution, the solid composition can be dissolved in a suitable amount of liquid composition to form a solution of appropriate concentration.

The container used for dissolution may be used not only for adding the solid composition to the container containing the liquid composition and dissolving the solid composition, but also for metering only the amount of water used for dissolution, and not for dissolving the solid composition.

The shape of the powder is not particularly limited, and examples thereof include a sphere shape and the like. The particle size of the powder is not particularly limited, and for example, a powder having an average particle size of 100 to 500 μm or 32 to 150 mesh (JIS Z8801-1:2006) is preferable in terms of mixing property, fluidity and solubility at the time of mixing the raw materials.
