Description
本発明は、低圧力成形により得られた、水又は湯に対する均一溶解性に優れ、且つ保存時、輸送時、取扱時における亀裂及び割れの発生が抑制又は防止された固体化粧料に関する。 The present invention relates to a solid cosmetic obtained by low-pressure molding, having excellent uniform solubility in water or hot water, and suppressing or preventing the generation of cracks and cracks during storage, transportation and handling.
現在市販されている入浴剤、芳香剤及び洗浄剤等の化粧料の形態としては、例えば、液状、粉末状、固体状、ゲル状が知られている。これらのうち固体化粧料は、例えば、液状化した化粧料原料を所望の型に入れ冷却固化させた後に型抜きする方法、粉末の化粧料原料を所望大きさに造粒する方法、所望物をカプセルに内包させる方法、粉末の化粧料原料を打錠成型機により加圧成形する方法、化粧料原料を手作業により所望形状に固める方法により製造されている。これらの方法により得られる固体化粧料は、例えば、使用される原料成分が同じ場合であっても、その製造法により得られる固体の硬さや弾力性等が異なり、物理的にそれぞれ区別できる。
ところで、上記各方法により得られる固体化粧料の中でも加圧成形によって得られる従来の固体化粧料は、生産性に優れ、しかも表面硬度が高いため取扱い性にも優れる。
加圧成形により製造される従来の固体化粧料は、通常、打錠成型機を用いて１方向から１００ｋｇｆ／ｃｍ２以上の圧力により成形される。このように製造された固体化粧料は、硬度が高いが、弾力性がなく、衝撃により亀裂及び割れが生じ易いという欠点がある。そこで、商品化に際しては、水溶性高分子による表面コートが施されることが多い。しかし、表面コートが施された固体化粧料であっても、落下による強い衝撃を受けた場合には内部に亀裂が生じ割れ易くなり、また、使用時に表面のコート層が溶解しはじめた直後に割れが生じ、商品価値が著しく低下するという欠点がある。このような問題は、固体化粧料が内部に有形物を包埋している場合、並びに１個の固体化粧料が１０ｇ以上の場合に生じ易い。
前記打錠成型機を用いて高圧力により成形される固体化粧料は、高圧力成形によって溶解性が低下するため、通常、発泡成分としての有機酸及び炭酸塩を含むことが多い。しかし、発泡成分を含む場合であっても高圧力により成形されているために、必ずしも溶解性が十分であるとは言い難い。また、従来の固体化粧料では加圧成形時の加圧が１方向からの高圧で行なわれているために、球状、タマゴ形状又は楕円状に成形し難く、更に、高圧によって変形が生じる樹脂製玩具等の有形物を包埋できない。
そこで、上記課題を解決するために、加圧成形時の圧力を低圧にすることが考えられる。しかし、圧力を低くすると成形自体が困難であり、成形できた場合でも亀裂及び割れの発生が抑制できない。特に、有形物を包埋した揚合には保存時における亀裂又は割れが発生するか、若しくは使用時に水又は湯に接触させた直後に割れが生じ均一溶解できないという問題が生じる。As cosmetic forms such as bathing agents, fragrances and cleaning agents currently on the market, for example, liquids, powders, solids, and gels are known. Among these, solid cosmetics include, for example, a method in which a liquefied cosmetic raw material is placed in a desired mold and solidified by cooling and then die-cut, a method in which a powdered cosmetic raw material is granulated to a desired size, and a desired product. It is manufactured by a method of encapsulating in a capsule, a method of pressing a powdery cosmetic raw material with a tableting machine, and a method of manually hardening the cosmetic raw material into a desired shape. The solid cosmetics obtained by these methods can be physically distinguished from each other, for example, even if the raw material components used are the same, the solids obtained by the production method have different hardness and elasticity.
By the way, among the solid cosmetics obtained by the above-described methods, the conventional solid cosmetics obtained by pressure molding are excellent in productivity, and are excellent in handleability because of high surface hardness.
Conventional solid cosmetics produced by pressure molding are usually molded at a pressure of 100 kgf / cm 2 or more from one direction using a tableting molding machine. The solid cosmetics produced in this way have high hardness, but are not elastic and have the disadvantages that cracks and cracks are likely to occur due to impact. Therefore, in commercialization, surface coating with a water-soluble polymer is often applied. However, even in the case of a solid cosmetic with a surface coat applied, if it is subjected to a strong impact due to dropping, it will be cracked and easily cracked inside, and immediately after the surface coat layer starts to dissolve during use There is a drawback that cracking occurs and the commercial value is significantly reduced. Such a problem is likely to occur when the solid cosmetic has a tangible material embedded therein and when one solid cosmetic is 10 g or more.
Solid cosmetics molded by high pressure using the tableting molding machine usually contain organic acids and carbonates as foaming components because the solubility is reduced by high pressure molding. However, even if it contains a foaming component, it is difficult to say that the solubility is sufficient because it is molded at a high pressure. Further, in the conventional solid cosmetics, since the pressurization at the time of pressure molding is performed at a high pressure from one direction, it is difficult to mold into a spherical shape, an egg shape or an ellipse shape, and further, a resin product which is deformed by a high pressure. Cannot embed tangible objects such as toys.
Therefore, in order to solve the above problems, it is conceivable to reduce the pressure during pressure molding. However, if the pressure is lowered, the molding itself is difficult, and even if molding is possible, the occurrence of cracks and cracks cannot be suppressed. In particular, in the hoisting in which a tangible object is embedded, there is a problem that cracks or cracks occur during storage, or cracks occur immediately after contact with water or hot water during use and cannot be uniformly dissolved.
本発明の目的は、取扱いが良好であり、保存時、使用時、取扱い時に亀裂及び割れの発生が抑制又は防止され、且つ使用時における均一溶解性に優れた、入浴剤、芳香剤又は洗浄剤等の固体化粧料を提供することにある。
本発明の他の目的は、内部に有形物を含み、球状、タマゴ形状又は楕円形状等の形状を有し、取扱いが良好で、保存時、使用時、取扱い時に、亀裂及び割れの発生が抑制又は防止され、且つ使用時における溶解性に優れた入浴剤、芳香剤又は洗浄剤等の固体化粧料を提供することにある。
本発明者らは、上記課題を解決するために鋭意検討した。まず、発泡性の固体化粧料を低圧で成形し、打錠成型機を用いて高圧下に成形された従来の固体化粧料と見かけ上同程度の硬度を有する固形物の作製を試みた。しかし、低圧による成形であるために成形不能であったり、成形できたとしても非常に脆いものであった。そこで、化粧料原料について種々検討した結果、特定分子量のポリエチレングリコール（ＰＥＧ）を流動化して用い、且つ発泡成分として特定の有機酸を用いることにより、低圧であっても従来の固体化粧料と見かけ上同程度の硬度を有する固形物が得られることを見出した。ところが、このようにして得られる固形物は、低圧成形されていても、必ずしも亀裂及び割れが十分に抑制できるものではなく、特に、有形物を包埋した場合には保存時において亀裂や割れを抑制することが困難であった。
そこで、更に鋭意検討した結果、特定分子量のＰＥＧを流動化させる溶剤としてジプロピレングリコール（ＤＰＧ）及び／又は１，３−ブチレングリコール（１，３−ＢＧ）を含む溶剤を用い、好ましくは発泡成分としての有機酸としてクエン酸を用い、且つ加圧成形する化粧料原料を、湿潤粉末とし、特定圧力で加圧成形することによって得られる固形物が、高さ１ｍからコンクリート床に落下させた際にも、亀裂及び割れが生じずに若干凹む程度の弾性力を有し、更には均一溶解性に優れる従来にない固体化粧料が得られることを見出し、本発明を完成させた。
即ち、本発明によれば、クエン酸、フマル酸、酒石酸、アジピン酸及びコハク酸からなる群より選択される１種又は２種以上の有機酸及び炭酸塩からなる発泡成分と、無水硫酸ナトリウムと、ＤＰＧ及び／又は１，３−ＢＧを含む溶剤により流動化させた平均分子量５００〜３７００のＰＥＧとを含む水溶性湿潤粉末を、圧力０．５〜１０ｋｇｆ／ｃｍ２で加圧成形して得た、比重１ｇ／ｃｍ３を超える固体化粧料が提供される。
また本発明によれば、前記水溶性湿潤粉末に、有形物を包埋し圧力０．５〜１０ｋｇｆ／ｃｍ２で加圧成形して得た、比重１ｇ／ｃｍ３を超える有形物含有固体化粧料が提供される。
発明の好ましい実施の態様
以下本発明を更に詳細に説明する。
本発明の固体化粧料は、打錠成形機により高圧力で加圧成形された従来の固体化粧料と見かけ上同等の硬度を有し、高さ１ｍからコンクリート床に落下させた際に亀裂及び割れが生じずに若干凹む程度の弾性力を有する。ここで、従来の固体化粧料と見かけ上同等の硬度とは、硬度計により測定したものではなく、触った感じが従来の錠剤程度のハードな硬さを有し、ほぼ同様な取扱いができることを意味する。
本発明の固体化粧料は、加圧によって成形しうる特定の水溶性湿潤粉末を、特定の圧力で加圧成形して得られる。ここで、湿潤粉末とは、例えば、原料となる発泡成分及び無水硫酸ナトリウム等の粉末が、特定の溶剤により流動化したＰＥＧ等により湿った状態となった粉末を意味する。また、水溶性湿潤粉末とは、該粉末を構成するほとんどの成分が水溶性であることを意味し、例えば、水不溶性である油溶性芳香成分等を含んでいても良い。
本発明の固体化粧料を製造するための前記水溶性湿潤粉末は、特定の有機酸及び炭酸塩からなる発泡成分と、無水硫酸ナトリウムと、特定溶剤により流動化させた特定分子量のＰＥＧとを含み、必要に応じて芳香成分及び／又は洗浄成分を更に含む。これら発泡成分、無水硫酸ナトリウム、特定溶剤を含むＰＥＧ、必要に応じて含ませる芳香成分及び／又は洗浄成分の合計量は、後述する有形物を除く固体化粧料中に９０重量％以上、特に、９５重量％以上が好ましい。従って、有形物を除く固体化粧料には、例えば、１０重量％未満、特に５重量％未満の色素等の他の成分が含まれていても良い。
前記特定の有機酸及び炭酸塩からなる発泡成分は、水分と反応し、炭酸ガスを発生し、固体化粧料の溶解性を補助する成分である。発泡成分は粉体として使用でき、その粒径は、原料として加圧によって成形しうるものであれば良い。
前記特定の有機酸は、クエン酸、フマル酸、酒石酸、アジピン酸及びコハク酸からなる群より選択される１種又は２種以上である。特に、本発明の固体化粧料における発泡力及び均一溶解性の点でクエン酸の使用が好ましい。
前記炭酸塩としては、例えば、炭酸ナトリウム、炭酸水素ナトリウム、セスキ炭酸ナトリウム、これらのカリウム塩が挙げられる。
発泡成分としての有機酸及び炭酸塩の配合割合は、重量比で通常１：０．２〜３．０であり、特に１：１に近い割合が望ましい。また、有形物を除く固体化粧料中の前記有機酸及び炭酸塩の合計の含有割合は、所望の溶解性を得るために３０〜９０重量％が好ましい。
前記無水硫酸ナトリウムは、得られる固体化粧料の比重を、１ｇ／ｃｍ３を超えるようにし、固体化粧料を水又は湯に投入した際に浮遊しないようにするため等に作用し、且つ本発明において加圧成形性や均一溶解性を悪化させない成分である。従って、固体化粧料中の無水硫酸ナトリウムの配合割合は、固体化粧料の比重を勘案して適宜決定することができるが、通常、１〜５０重量％の範囲から適宜選択することができる。無水硫酸ナトリウムは、粉体として使用でき、その粒径は原料として加圧によって成形しうるものであれば良い。

It is to provide solid cosmetics such as.
Another object of the present invention includes a tangible object inside, has a shape such as a spherical shape, an egg shape or an oval shape, is well handled, and suppresses the generation of cracks and cracks during storage, use and handling. Another object of the present invention is to provide a solid cosmetic such as a bath agent, a fragrance or a cleaning agent which is prevented and has excellent solubility during use.
The present inventors diligently studied to solve the above problems. First, an effervescent solid cosmetic was molded at a low pressure, and an attempt was made to produce a solid having apparently the same degree of hardness as a conventional solid cosmetic molded under high pressure using a tableting molding machine. However, since the molding is performed at a low pressure, it is impossible to mold or even if it can be molded, it is very brittle. Therefore, as a result of various investigations on cosmetic raw materials, it appears that conventional solid cosmetics are used even at low pressure by fluidizing and using a specific molecular weight polyethylene glycol (PEG) and using a specific organic acid as a foaming component. It has been found that a solid having the same degree of hardness can be obtained. However, even if the solid material obtained in this way is low-pressure molded, cracks and cracks are not necessarily suppressed sufficiently. It was difficult to suppress.
Therefore, as a result of further intensive studies, a solvent containing dipropylene glycol (DPG) and / or 1,3-butylene glycol (1,3-BG) is used as a solvent for fluidizing PEG having a specific molecular weight, preferably a foaming component When citric acid is used as the organic acid and the cosmetic raw material to be pressure-molded is a wet powder and the solid material obtained by pressure-molding at a specific pressure is dropped from a height of 1 m onto a concrete floor In addition, the present inventors have found that an unprecedented solid cosmetic having an elastic force that is slightly recessed without causing cracks and cracks and having excellent uniform solubility can be obtained.
That is, according to the present invention, a foaming component composed of one or more organic acids and carbonates selected from the group consisting of citric acid, fumaric acid, tartaric acid, adipic acid and succinic acid, anhydrous sodium sulfate, And water-soluble wet powder containing PEG having an average molecular weight of 500 to 3700 fluidized with a solvent containing DPG and / or 1,3-BG, and obtained by pressure molding at a pressure of 0.5 to 10 kgf / cm 2. In addition, a solid cosmetic having a specific gravity exceeding 1 g / cm 3 is provided.
According to the present invention, the tangible material-containing solid makeup having a specific gravity exceeding 1 g / cm 3 obtained by embedding a tangible material in the water-soluble wet powder and press-molding at a pressure of 0.5 to 10 kgf / cm 2. Fees are provided.
Preferred Embodiments of the Invention The present invention will be described in more detail below.
The solid cosmetic of the present invention has apparently the same hardness as a conventional solid cosmetic that has been pressure-molded with a tableting machine at a high pressure, and when dropped from a height of 1 m onto a concrete floor, It has an elastic force that is slightly recessed without cracking. Here, the apparently equivalent hardness to the conventional solid cosmetic is not measured by a hardness meter, but the touch feeling has a hardness as hard as a conventional tablet and can be handled in substantially the same way. means.
The solid cosmetic of the present invention is obtained by pressure-molding a specific water-soluble wet powder that can be molded by pressing at a specific pressure. Here, the wet powder means, for example, a powder in which a foaming component as a raw material and a powder such as anhydrous sodium sulfate are wetted by PEG fluidized with a specific solvent. The water-soluble wet powder means that most components constituting the powder are water-soluble, and may contain, for example, an oil-soluble fragrance component that is water-insoluble.
The water-soluble wet powder for producing the solid cosmetic of the present invention comprises a foaming component composed of a specific organic acid and carbonate, anhydrous sodium sulfate, and PEG having a specific molecular weight fluidized with a specific solvent. If necessary, it further contains a fragrance component and / or a cleaning component. The total amount of these foaming components, anhydrous sodium sulfate, PEG containing a specific solvent, a fragrance component and / or a cleaning component to be included as necessary is 90% by weight or more in solid cosmetics excluding tangible materials described later, 95 weight% or more is preferable. Therefore, the solid cosmetic excluding tangible materials may contain other components such as a pigment of less than 10% by weight, particularly less than 5% by weight.
The foaming component comprising the specific organic acid and carbonate is a component that reacts with moisture to generate carbon dioxide gas and assists the solubility of the solid cosmetic. The foaming component can be used as a powder, and the particle size thereof may be any material that can be molded by pressing 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, it is preferable to use citric acid from the viewpoint of foaming power and uniform solubility in the solid cosmetic of the present invention.
Examples of the carbonate include sodium carbonate, sodium bicarbonate, sodium sesquicarbonate, and potassium salts thereof.
The mixing ratio of the organic acid and carbonate as the foaming component is usually 1: 0.2 to 3.0 by weight, and a ratio close to 1: 1 is particularly desirable. Further, the total content of the organic acid and carbonate in the solid cosmetic excluding tangible materials is preferably 30 to 90% by weight in order to obtain desired solubility.
The anhydrous sodium sulfate acts so that the specific gravity of the obtained solid cosmetic exceeds 1 g / cm 3 , so as not to float when the solid cosmetic is poured into water or hot water, and the like. Is a component that does not deteriorate the pressure moldability and uniform solubility. Therefore, the blending ratio of anhydrous sodium sulfate in the solid cosmetic can be appropriately determined in consideration of the specific gravity of the solid cosmetic, but can be appropriately selected from the range of 1 to 50% by weight. Anhydrous sodium sulfate can be used as a powder, and the particle size thereof may be any material that can be molded by pressing as a raw material.
The solvent used in the present invention contains DPG and / or 1,3-BG. Preferably only DPG and / or 1,3-BG, particularly preferably DPG alone. DPG and / or 1,3-BG is necessary for dispersing PEG throughout the raw material and imparting the characteristic hardness and elasticity in the present invention described above. The PEG used in the present invention dissolves in, for example, ethanol, but when only ethanol is used without using DPG and / or 1,3-BG, the desired effect of the present invention in which cracking and cracking can be suppressed. Cannot be obtained. In particular, when a tangible object is embedded, there is a high possibility of cracking or cracking during storage.
The average molecular weight of the PEG used in the present invention is 500-3700. PEG having such a molecular weight usually exhibits a flake state from a paste state. For example, a commercially available product or a mixture obtained by mixing a commercially available product to have a desired molecular weight can be used. When the average molecular weight of PEG is out of the above range, the press moldability deteriorates, and it is difficult to impart desired hardness and elastic force to the solid cosmetic.
The specific molecular weight PEG fluidized by the specific solvent is, for example, a method in which the PEG is mixed with a solvent containing DPG and / or 1,3-BG and heated to about 60 to 70 ° C. to dissolve the PEG. Is obtained. At this time, the blending ratio of the solvent containing DPG and / or 1,3-BG and PEG can be appropriately selected so that PEG fluidizes, but in order to obtain the desired effect of the present invention more effectively, the weight The ratio is preferably 1: 0.5 to 20, particularly 1: 0.5 to 10. In addition, the content ratio of the PEG in the solid cosmetic excluding tangible materials is preferably 2 to 50% by weight.
The fragrance component that can be contained in the water-soluble wet powder as needed is not particularly limited, and a desired fragrance component can be appropriately selected and used. The form of the fragrance component may be any of liquid, powder, gel and the like as long as the water-soluble wet powder can be pressure-molded, but is preferably powder. The blending ratio in the case of using the fragrance component can be appropriately selected depending on the type and expected fragrance, but from the viewpoint of pressure moldability, it is usually 50% by weight or less, preferably 0% in the solid cosmetic excluding tangible substances. 0.01 to 30% by weight. By containing such a fragrance component, the solid cosmetic of the present invention can be used as a fragrance.
The cleaning component that can be contained in the water-soluble wet powder as needed is not particularly limited. Examples of the cleaning component include various surfactants such as anionic surfactants, nonionic surfactants, and amphoteric surfactants, enzymes, and mixtures thereof. The form of the cleaning component may be liquid, powder, gel or the like as long as the water-soluble wet powder can be pressure-molded, but is preferably powder. The blending ratio in the case of using the cleaning component can be appropriately selected depending on the type and expected cleaning action, but from the viewpoint of pressure moldability, it is usually 50% by weight or less in the solid cosmetic excluding tangibles, preferably 10 to 50% by weight. By containing such a cleaning component, the solid cosmetic of the present invention can be used as a cleaning agent.
In the water-soluble wet powder, the blending ratio of the foaming component and the fluidized PEG is preferably 1: 0.01 to 20, particularly 1: 0.1 to 15 by weight. If the blending ratio of the fluidized PEG is less than 0.01 with respect to the foaming component 1, strength cannot be imparted and molding is impossible, and if it exceeds 20, it becomes a slurry and molding is difficult, which is not preferable.
A tangible material may be embedded in the solid cosmetic of the present invention. The tangible object includes a water-insoluble tangible object or a water-soluble tangible object. Examples of the water-insoluble tangible material include a resin toy, a water-insoluble film, a water-insoluble capsule, and a water-insoluble gel. The water-insoluble tangible material 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 solid, a water-soluble capsule, and a water-soluble gel. The water-soluble tangible material can be preferably used when the solid cosmetic is a fragrance or a cleaning agent. For example, the water-soluble tangible material is manufactured by mixing a fragrance or a cleaning agent of a different type from the fragrance or cleaning agent added to the water-soluble wet powder The water-soluble tangible material which was made is mentioned.
The shape of the tangible object is not particularly limited, but may be relatively large such as a toy or a complicated shape. In general, the size of the tangible object is preferably selected as appropriate so that the thickness of the water-soluble wet powder existing between the outer surface of the tangible object 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, but when a solid cosmetic is used as a bath agent, it is preferably less than the specific gravity of the bath water so that the bath agent floats in the bath water when dissolved.
A method for embedding a tangible object is not particularly limited, and examples thereof include a method in which a concave portion is provided in advance in the water-soluble wet powder, and a tangible material is placed in the concave portion and then embedded.
The solid cosmetic of the present invention is prepared by applying the water-soluble wet powder or the water-soluble wet powder in which each tangible material is embedded to a pressure of 0.5 to 10 kgf / cm 2 , preferably 0.5 to 5 kgf / cm 2. Preferably, it is obtained by a method of pressure molding at 0.8 to 5 kgf / cm 2 . If the pressure is less than 0.5 kgf / cm 2 , molding is difficult or the desired strength cannot be imparted to the solid cosmetic, while if it exceeds 10 kgf / cm 2 , the desired solubility cannot be obtained, Moreover, the embedded tangible object is deformed and the commercial value is lowered.
The pressure molding is an improvement of a normal tableting machine, and can be performed by a single pressurization. However, the pressurization can be performed in two or more times within the pressure range. . In particular, when embedding a tangible object, divide the pressure into two or more times, lower the first pressure, and make the final pressure after the second time, so that the water-soluble wet powder is made into the outer shape of the tangible object. Can be packed closely along. In addition, when the shape of the solid cosmetic is spherical, egg-shaped, elliptical, or the like, pressurization from two or more directions can be performed. For example, when obtaining a spherical solid cosmetic, it can be performed by applying pressure from both directions using a pressure plate having two hemispherical recesses. In addition, the shape of solid cosmetics is not specifically limited, In addition to the said shape, the complex shape which carried out cube shape, a triangular prism, a star-shaped column, and also the shape of the doll may be sufficient.
The specific gravity of the solid cosmetic of the present invention exceeds 1 g / cm 3 so as not to float when it is poured into water or hot water, for example. Therefore, when the solid cosmetic is a bath agent, when it is poured into the bath water, it settles and dissolves in the bath water. When the solid cosmetic is a cleaning agent, it settles in water or hot water in a washing tub of a washing machine or the like and quickly dissolves. When the solid cosmetic is a fragrance, for example, it is precipitated and dissolved by being put in a toilet bowl or the like. When the solid cosmetic is a fragrance, it is not always necessary to use it in water or hot water. For example, it may be left in the air and gradually dissolved by moisture in the air. It may be used in which a proper amount is brought into contact with running toilet water and gradually dissolved.
The total weight of the solid cosmetic of the present invention is not particularly limited, but is preferably 10 to 300 g, particularly 50 to 300 g, in which the desired effect appears remarkably. In the case of such a total weight range, since it is larger than the conventional tablet-type solid cosmetic of about several grams, the possibility of cracking and cracking increases, but in the case of the solid cosmetic of the present invention, such a problem is caused. Is effectively suppressed or prevented.
The solid cosmetic of the present invention can be obtained by drying after the above pressure molding, but if necessary, for example, in order to improve surface deterioration and handleability due to contact with air during storage, It is also possible to react moisture such as steam with the surface of the solid cosmetic material to make only the surface a neutral salt. Moreover, in order to prevent more effectively the generation | occurrence | production of the crack at the time of preservation | save of a solid cosmetics, at the time of transportation, and use, a well-known shrink packaging can also be performed as needed.
The solid cosmetic of the present invention is light-impermeable and can be packaged in a bag-shaped packaging material in order to suppress or prevent discoloration and odor when stored for a long period of time and to maintain commercial value. it can. Examples of the packaging material include aluminum foil. Further, the solid cosmetic of the present invention can be put in a bag-shaped packaging material, decompressed using a decompression device, and sealed. Furthermore, the solid cosmetic of the present invention may be provided with a surface coat with a known water-soluble polymer component.
The solid cosmetic of the present invention comprises a specific foaming component, anhydrous sodium sulfate, and a specific molecular weight PEG fluidized with a solvent containing DPG and / or 1,3-BG, and if necessary, an aroma component or a washing Adopting a composition having a specific gravity exceeding 1 g / cm 3 obtained by pressure molding a water-soluble wet powder containing the components at a specific pressure, the handling is good, and cracks and cracks occur during storage, use and handling. The occurrence of cracks is suppressed or prevented, and the uniform solubility during use is excellent. Therefore, it is useful as a bath agent, fragrance or cleaning agent. In addition, since it is manufactured by low pressure molding, even if it is a solid cosmetic with tangible material embedded, there is almost no deformation of the tangible material, and there is some shrinkage of the tangible material during embedding, during storage etc. Even when a force for restoring the shrinkage is generated, cracks and cracks can be effectively suppressed or prevented.
The solid cosmetic of the present invention can be formed into a shape such as a spherical shape, an egg shape, an elliptical shape, or the like other than the conventional tablet shape by being manufactured by pressure molding from two or more directions.
The solid cosmetic of the present invention can be sustained by long-term storage by suppressing or preventing discoloration and odor by storing with a light-impermeable packaging material.
