Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the present invention, which has excellent uniform solubility in water or hot water obtained by low pressure molding, and suppresses or prevents the occurrence of cracks and cracks during storage, transportation, handling and the like. In addition, the present invention relates to a solid cosmetic as a bath additive, a fragrance, a detergent, or the like.

[0002]

2. Description of the Related Art As cosmetics such as bath salts, fragrances and detergents which are currently commercially available, for example, liquid, powder, solid and gel forms are known. Among these, solid cosmetics include, for example, a method in which a liquefied cosmetic material is put into a desired mold, cooled and solidified, and then die-cut, a method in which a powdered cosmetic material is granulated to a desired size, It is manufactured by a method of encapsulating in a capsule, a method of press-forming a powdery cosmetic material by a tableting machine or the like, a method of manually solidifying a cosmetic material into a desired shape, and the like. Solid cosmetics obtained by these methods, for example, even if the raw material components used are the same, the solids obtained by the production method have different hardness and elasticity, etc., and can be physically distinguished from each other. is there. By the way, among the solid cosmetics obtained by each of the above methods, the conventional solid cosmetics obtained by pressure molding are excellent in productivity and also excellent in handleability due to high surface hardness. Conventional solid cosmetics manufactured by such pressure molding are usually molded by a tableting machine at a pressure of 100 kgf / cm ² or more from one direction. The solid cosmetics produced in this way have high hardness but lack elasticity, and have the disadvantage that cracks and cracks are easily generated by impact. Therefore, in commercialization, a surface coat with a water-soluble polymer or the like is often applied.
However, even in the case of a solid cosmetic having such a surface coat, when it receives a strong impact due to dropping or the like, a crack is formed inside and it is easily broken, and the coat layer on the surface dissolves during use. There is a defect that cracks occur immediately after the start, and the commercial value is significantly reduced. Such a problem is likely to occur when the solid cosmetic has a tangible substance embedded therein or when one solid cosmetic weighs 10 g or more. In addition, conventional solid cosmetics that are molded from a single direction with a pressure of 100 kgf / cm ² or more using a tableting molding machine have low solubility due to high-pressure molding. Often contains carbonate. However, even if such a foaming component is contained, it is hard to say that the solubility is always sufficient because the foaming component is molded under high pressure. Furthermore,
In conventional solid cosmetics, since the pressure during pressure molding is performed at a high pressure from one direction, it is difficult to mold into a spherical, egg-shaped or elliptical shape. There is also a problem that tangible objects such as toys cannot be embedded.

[0003]

Therefore, in order to solve the above-mentioned problems, it is conceivable to reduce the pressure during the pressure molding. However, when the pressure is simply lowered, there is a problem that the molding itself is difficult, and even if the molding can be performed, the occurrence of cracks and cracks cannot be suppressed. In particular, when a tangible object is embedded, there arises a problem that cracks and cracks occur during storage and cracks occur immediately after contact with water or hot water during use, making it impossible to dissolve uniformly.

Accordingly, an object of the present invention is to provide a bath preparation, which is excellent in handling, suppresses or prevents the occurrence of cracks and cracks during storage, use and handling, and is excellent in uniform solubility during use. An object of the present invention is to provide a solid cosmetic such as a fragrance or a detergent. Another object of the present invention is to provide a tangible object inside, have a shape such as a spherical shape, an egg shape, and an elliptical shape, and handle well, and when stored, used, handled, etc., cracks and cracks, etc. An object of the present invention is to provide a solid cosmetic such as a bath additive, a fragrance, a detergent, or the like, in which generation of odor is suppressed or prevented, and which has excellent solubility during use.

[0005]

Means for Solving the Problems The present inventors have intensively studied to solve the above problems. First, a foaming solid cosmetic as a bathing agent, a fragrance or a detergent is molded at a low pressure, and has a hardness approximately equal to that of a conventional solid cosmetic molded under high pressure using a tableting machine. An attempt was made to produce a solid having the same. However, the molding was not possible due to the molding under low pressure, or was very brittle even if it could be molded. Therefore, as a result of various studies on cosmetic raw materials, polyethylene glycol of a specific molecular weight (hereinafter abbreviated as PEG)
It has been found that by fluidizing and using a specific organic acid as a foaming component, a solid having apparently the same hardness as the above-mentioned conventional solid cosmetics can be obtained even at a low pressure. However, even if the solid obtained in this way is formed at a low pressure, cracks and cracks cannot always be sufficiently suppressed.In particular, when a tangible object is embedded, cracks or It was difficult to suppress cracking. Therefore, as a result of further intensive studies, dipropylene glycol (hereinafter, abbreviated as DPG) and / or 1,3-butylene glycol (hereinafter, abbreviated as 1,3-BG) are included as a solvent for fluidizing PEG having a specific molecular weight. Using a solvent, preferably using citric acid as an organic acid as a foaming component, and a cosmetic material to be pressure-formed, a wet powder, a solid obtained by pressure-forming at a specific pressure,
We found that even when dropped on a concrete floor from a height of 1 m, it has elasticity enough to dent slightly without cracking or cracking, and that an unprecedented solid cosmetic with excellent uniform solubility can be obtained. The present invention has been completed.

That is, according to the present invention, a foaming component comprising one or more organic acids and carbonates selected from the group consisting of citric acid, fumaric acid, tartaric acid, adipic acid and succinic acid, Sodium sulfate, DPG and / or 1,3-B
With an average molecular weight of 500 to 3700 fluidized by a solvent containing G
The water-soluble wet powder containing the PEG, obtained by pressing at a pressure 0.5~5kgf / cm ^2, a solid cosmetic is provided in excess of gravity 1 g / cm ^3. Further, according to the present invention, there is provided a solid cosmetic having a specific gravity of more than 1 g / cm ³ obtained by embedding a tangible material in the water-soluble wet powder and press-molding the material at a pressure of 0.5 to 5 kgf / cm ^2. You.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. The solid cosmetic of the present invention has apparently the same hardness as that of a conventional solid cosmetic that has been molded under high pressure by a tablet molding machine, and has a crack or a crack when dropped on a concrete floor from a height of 1 m. It has an elastic force that is slightly depressed without cracking. Here, the hardness apparently equivalent to that of the conventional solid cosmetics is not measured by a hardness meter, but the touch feel has a hardness as high as that of a conventional tablet and can be handled in substantially the same manner. means.

[0008] The solid cosmetic of the present invention can be obtained by press-forming a specific water-soluble wet powder that can be formed by pressing under a specific pressure. Here, the wet powder refers to, for example, a powder in which a powder of a foaming component or anhydrous sodium sulfate as a raw material is wet by PEG fluidized by a specific solvent. The water-soluble wet powder for producing the solid cosmetic of the present invention contains a foaming component composed of a specific organic acid and a carbonate, anhydrous sodium sulfate, and PEG having a specific molecular weight fluidized with a specific solvent. And, if necessary, an aromatic component and / or a cleaning component. The total amount of these foaming components, anhydrous sodium sulfate, PEG containing a specific solvent, and aroma components and / or cleaning components to be contained as necessary is 90% by mass or more, especially in solid cosmetics excluding tangible materials described below. , 95% by mass or more. Therefore, the solid cosmetics excluding tangibles may contain other components such as pigments, for example, in an amount of less than 10% by mass, particularly less than 5% by mass.

The foaming component comprising the specific organic acid and carbonate is a component which reacts with moisture to generate carbon dioxide gas and acts to assist the solubility of the obtained solid cosmetic. The foaming component can be used as a powder, and its particle size may be any as long as it can be molded by pressure as a raw material. The specific organic acid is one or more selected from the group consisting of citric acid, fumaric acid, tartaric acid, adipic acid and succinic acid. In particular, the use of citric acid is preferred in terms of foaming power and uniform solubility in the solid cosmetic of the present invention. Examples of the carbonate include sodium carbonate, sodium hydrogen carbonate, sodium sesquicarbonate, and potassium salts thereof. The compounding ratio of the organic acid and the carbonate as the foaming component is usually 1: 0.2 to 3.0 in terms of mass ratio, and a ratio close to 1: 1 is particularly desirable. In addition, the total content of the organic acid and carbonate in the solid cosmetic excluding tangibles is preferably 30 to 90% by mass in order to obtain a desired solubility.

The anhydrous sodium sulfate acts to make the specific gravity of the obtained solid cosmetic exceed 1 g / cm ^{3 and} to prevent the solid cosmetic from floating when poured into water or hot water. In addition, in the present invention, it is a component that does not deteriorate the pressure moldability, uniform solubility, and the like. Therefore, the mixing ratio of anhydrous sodium sulfate in the solid cosmetic can be appropriately determined in consideration of the specific gravity of the solid cosmetic and the like, but is usually 1 to 5
It is preferable to appropriately select from the range of 0% by mass. Anhydrous sodium sulfate can be used as a powder, the particle size of which is
Any material can be used as long as it can be molded by pressure.

The solvent used in the present invention contains DPG and / or 1,3-BG. Preferably, it is only DPG and / or 1,3-BG, and especially DPG alone is preferable. This DPG and / or 1,
3-BG is necessary for dispersing PEG throughout the raw material and imparting the above-mentioned characteristic hardness and elasticity in the present invention. The PEG used in the present invention, for example, dissolves in ethanol and the like, but when only ethanol is used without using DPG and / or 1,3-BG, the desired PEG of the present invention, in which cracking and cracking can be suppressed. No effect. In particular, when a tangible object is embedded, the possibility of cracking or cracking during storage or the like increases. On the other hand, the average molecular weight of the PEG used in the present invention is 500 to
3700. PEG having such a molecular weight usually exhibits a flake state from a paste state, and for example, a commercial product or a mixture of commercial products so as to have a desired molecular weight can be used. When the average molecular weight of PEG is out of the above range, the pressure moldability deteriorates, and it is difficult to impart desired hardness and elasticity to the obtained solid cosmetic of the present invention.

The PEG having a specific molecular weight fluidized by the specific solvent is, for example, mixed with a solvent containing DPG and / or 1,3-BG, and heated to about 60 to 70 ° C. to convert the PEG. It can be obtained by a method of dissolving or the like. At this time, the mixing ratio of the solvent containing DPG and / or 1,3-BG and PEG can be appropriately selected so that the PEG is fluidized, but in order to more effectively obtain the desired effect of the present invention, 1: 0.5-20 in ratio, especially
1: 0.5 to 10 is preferred. Further, the content ratio of the PEG in the solid cosmetic excluding tangible substances is preferably 2 to 50% by mass.

The fragrance component which can be contained in the water-soluble wet powder as required is not particularly limited, and a desired fragrance component can be appropriately selected and used. The form of the fragrance component, if the water-soluble wet powder can be pressed,
Any of liquid, powder, gel and the like may be used, but powder is preferred. The mixing ratio when using the fragrance component can be appropriately selected depending on the type and expected fragrance, but from the viewpoint of pressure moldability, usually 50% by mass or less, preferably 0.01% by mass, in solid cosmetics excluding tangible materials. ~ 30% by mass.
By incorporating such an aroma component, the solid cosmetic of the present invention can be used as an aroma or the like.

The washing component which can be contained in the water-soluble wet powder as required is not particularly limited, and in consideration of a desired washing effect, for example, an anionic surfactant, a nonionic surfactant, an amphoteric surfactant It can be appropriately selected from various surfactants such as activators and cleaning components such as enzymes. The form of the cleaning component may be any of a liquid form, a powder form, a gel form, and the like as long as the water-soluble wet powder can be press-molded, but is preferably a powder form. The mixing ratio in the case of using the above-mentioned cleaning component can be appropriately selected depending on the type and expected cleaning action. However, from the viewpoint of pressure moldability, it is usually 10 to 50% by mass in solid cosmetics excluding tangible materials. . By incorporating such a cleaning component, the solid cosmetic of the present invention can be used as a cleaning agent or the like.

In the water-soluble wet powder, the mixing ratio of the foaming component and the fluidized PEG is preferably 1: 0.01 to 20, more preferably 1: 0.1 to 15 by mass. If the blending ratio of the fluidized PEG is less than 0.01 with respect to the foaming component 1, molding cannot be performed because strength cannot be imparted, and if it exceeds 20, it becomes a slurry and molding is difficult, which is not preferable. .

The solid cosmetic of the present invention may have a tangible material embedded therein. The tangible includes a water-insoluble tangible or a water-soluble tangible. Examples of water-insoluble tangible materials include, for example, resin toys, water-insoluble films, water-insoluble capsules,
Water-insoluble gels and the like can be mentioned. The water-insoluble tangible is particularly useful when a solid cosmetic is used as a bath agent. Examples of the water-soluble tangible material include a water-soluble film, a water-soluble capsule, and a water-soluble gel. Water-soluble tangibles can be preferably used particularly when solid cosmetics are used as a fragrance or a detergent, for example,
A water-soluble tangible material produced by blending a different type of fragrance or cleaning agent with the fragrance or cleaning agent blended in the water-soluble wet powder is exemplified. The shape of the tangible object is not particularly limited,
A relatively large toy or the like and a complicated shape may be used. The size of the tangible material is usually preferably appropriately selected so that the thickness of the water-soluble wet powder present between the outer surface of the tangible material and the outer surface of the obtained solid cosmetic is 1 cm or more. . The specific gravity of the tangible material is not particularly limited, and when the solid cosmetic is used as a bathing agent, the specific gravity is preferably equal to or lower than the specific gravity of the bathing water so that the bathing agent floats in the bathing water when dissolved. The method of embedding the tangible material is not particularly limited, for example,
A method is provided in which a concave portion is provided in advance in the water-soluble wet powder, a tangible object is placed in the concave portion, and then embedded.

The solid cosmetic of the present invention comprises the above-mentioned water-soluble wet powder or a water-soluble wet powder in which each tangible material is embedded.
It can be obtained by pressure molding at a pressure of 0.5 to 5 kgf / cm ² , preferably 0.8 to 5 kgf / cm ² . Pressure is 0.5kgf /
If it is less than ² cm, molding is difficult or the desired strength cannot be imparted to the resulting solid cosmetic, while if it exceeds 5 kgf / cm ² , the desired solubility cannot be obtained and the solid cosmetic is embedded. It interferes with tangible objects and reduces their commercial value. The pressure molding can be performed by a single pressurization, for example, by improving a usual tablet press, but if the pressure is within the above-mentioned pressure range, the pressurization is performed by 2 times.
It can also be performed in multiple times. In particular, when embedding a tangible material, the pressure is divided into two or more times, the first pressure is reduced, and the final pressure is applied from the second time onward, so that the water-soluble wet powder becomes the outer shape of the tangible material. Can be densely packed along. When the shape of the obtained solid cosmetic is spherical, egg-shaped or elliptical, pressure can be applied from two or more directions. For example, when obtaining a spherical solid cosmetic, it can be performed by applying pressure from both directions using a pressure plate or the like having two hemispherical concave portions. In addition, the shape of the solid cosmetic of the present invention is not particularly limited, and may be a complex shape in the shape of a cube, a triangular prism, a star-shaped column, or even a doll, in addition to the above shapes.

The specific gravity of the solid cosmetic of the present invention exceeds, for example, 1 g / cm ³ so as not to float when poured into water or hot water. Therefore, when the solid cosmetic is a bath additive, it sinks and dissolves in the bath when it is put into the bath. When the solid cosmetic is a cleaning agent, the solid cosmetic is settled in water or hot water in a washing tub of a washing machine or the like and rapidly dissolved. If the solid cosmetic is a fragrance,
For example, it is settled and dissolved by being put into a toilet or the like. The solid cosmetic as the fragrance is not necessarily required to be used by pouring it into water or hot water. For example, even if the solid cosmetic is left in the air and gradually dissolved by the moisture in the air, May be used by contacting an appropriate amount with flowing water and gradually dissolving.

The total weight of the solid cosmetic of the present invention is not particularly limited, but is 10 to 30 in which the desired effect of the present invention is remarkably exhibited.
0 g, especially 50-300 g, is preferred. In the case of this total weight range, since it is larger than the conventional tablet-type solid cosmetic of about several g, the possibility of cracks and cracks increases, but in the case of the solid cosmetic of the present invention, such a problem is effective. Is suppressed or prevented.

The solid cosmetic of the present invention comprises
It can be obtained by drying, but if necessary, for example,
In order to improve the surface deterioration and handling properties due to contact with air during storage and the like, the surface of the obtained solid cosmetic can be reacted with moisture such as steam, and only the surface can be made into a neutral salt. In order to further effectively prevent the occurrence of cracks and cracks during storage, transportation, and use of the solid cosmetic, known shrink packaging can be performed as necessary. The solid cosmetic of the present invention suppresses or prevents discoloration or odor during long-term storage, and in order to maintain commercial value,
It is light impermeable and can be packaged in a bag-like packaging material that can be sealed. Examples of such a packaging material include aluminum foil and the like. Further, the solid cosmetic of the present invention can be put in a bag-shaped packaging material, and the pressure can be reduced by using a decompression device used in the food field and the like, followed by sealing.
Further, the solid cosmetic of the present invention may be coated with a known water-soluble polymer component or the like.
