Description

FOAMY COSMETIC MATERIAL "

The present invention relates to a foam cosmetic.

Powder formulations are known to impart a sense of smoothness to the user. Conventional powder formulations are spread over many fields such as powder type, water type, gel type, and spray type. This type of product has problems such as loss due to scattering and overflowing during application, stickiness due to the surfactant to be compounded, and the like, so that it is difficult to efficiently give a sense of smoothness.

In order to solve the above problems, for example, there is known an emulsified aerosol composition containing an aqueous raw liquid containing a surfactant and a powder and a liquefied gas and emulsifying the aqueous raw liquid and the liquefied gas (Patent Document 1). Patent Document 1 discloses that an aerosol composition is discharged in a foam state.

Japanese Patent Application Laid-Open No. 2013-112798

However, in Patent Document 1, since a surfactant is used to form a foam, a surfactant becomes essential and the problem of stickiness has remained. On the other hand, when the amount of the surfactant is decreased, there is a problem that bubbles are not formed or the shape of the formed foam changes in a short period of time. Therefore, there is a problem that it is difficult to employ a means for reducing the amount of the surfactant.

Accordingly, it is an object of the present invention to provide a foam composition which is capable of forming foam with a smooth and smooth gauze of quality (foam quality), and also that the shape of the foam formed does not change in a short time, Is the stability of the bubbles over time) is to provide a foam-like cosmetic composition capable of supplying an excellent foam. It is still another object of the present invention to provide a foam cosmetic composition which is free from stickiness and can impart a smooth feeling.

That is, the gist of the present invention is that,

A foam cosmetic comprising a stock solution and a propellant filled in an aerosol container,

Wherein the stock solution comprises a powder selected from the group consisting of silicon-coated silica and silica-coated silicon,

Wherein the content of the powder in the stock solution is 5.0 mass% or more.

According to the present invention, it is possible to provide a foam cosmetic composition capable of supplying bubbles having a smooth and smooth texture and excellent foam stability. Further, according to the present invention, it is possible to provide a foam-like cosmetic composition which can give a smooth feeling without causing tackiness.

In the foam cosmetic of the present invention, the stock solution and the jet agent are filled in an aerosol container. The foam cosmetic composition of the present invention forms foam when used, that is, when it is discharged from an aerosol container or after it is attached to an object.

In the foam cosmetic of the present invention, the stock solution contains a powder (at least one powder) selected from the group consisting of silicone-coated silica and silica-coated silicone. In the present specification, the " powder selected from the group consisting of silicon-coated silica and silica-coated silicon " is sometimes referred to as " powder A ". By using the powder A, since the undiluted solution and the injecting agent can form the picking emulsion particularly effectively, by ejecting the contents from the aerosol container, it is possible to form a bubble having a smooth and smooth texture and excellent stability. In addition, although the powder A is mixed in a relatively large amount, the powder A hardly becomes caking in the container, and storage stability is improved. Each constituent component of the foam cosmetic of the present invention will be described below.

The undiluted solution contains at least powder A and a medium. In the present specification, the stock solution refers to all components other than the propellant among the components filled in the aerosol container. As described above, the undiluted solution also includes powder insoluble in the medium.

As the powder A, there may be mentioned one or more kinds of powders selected from the group consisting of silicone-coated silica and silica-coated silicone. The powder A may be used alone, or two or more kinds may be used.

The silicone-coated silica is a powder obtained by coating a silica (silicic anhydride) powder with a silicone compound. The silicone compound is not particularly limited, and examples thereof include methylhydrogenpolysiloxane and the like.

The silica-coated silicon is a powder obtained by coating a silicon powder with silica (silicic anhydride). The silicone powder is not particularly limited, and examples thereof include crosslinked methylpolysiloxane powder and the like.

The powder A is preferably a powder coated with a polyhydric alcohol from the viewpoint of improving the stability of the foam (bubble retention) and the production stability. That is, the powder A is preferably a powder (at least one powder) selected from the group consisting of silicone-coated silica coated with a polyhydric alcohol and silica-coated silicone coated with a polyhydric alcohol. It is considered that the hydrophobicity of the powder is weakened to some extent and the balance between the hydrophilic property and the hydrophobic property is more appropriate by further coating the silicone-coated silica or the silica-coated silicone with the polyhydric alcohol. The use of a powder coated with a polyhydric alcohol is preferable because the medium, for example, water and the powder A are easily mixed. Therefore, it is preferable because the production stability is improved. Examples of the polyhydric alcohol include, but are not limited to, 1,3-butylene glycol (1,3-BG). Powder A is available as a commercial product.

The content of the powder A in 100% by mass of the undiluted solution is preferably 5.0% by mass or more, more preferably 7.0% by mass or more, and further preferably 10.0% by mass or more from the viewpoints of foam- On the other hand, the content is preferably 20.0% by mass or less, and more preferably 15.0% by mass or less, from the viewpoint of preventing whitening (phenomenon in which the cosmetic is precipitated after coating and drying). In the case where two or more kinds of powders A are contained in the stock solution, the above-mentioned " content of powder A " means the total amount of all kinds of powder A in the stock solution.

The particle diameter of the powder A is not particularly limited. For example, from the viewpoint of imparting a feeling of smooth running, it is preferably 0.5 탆 or more and more preferably 1.0 탆 or more, while the particle diameter of the O / W emulsion particle Is preferably 10.0 占 퐉 or less, and more preferably 5.0 占 퐉 or less from the viewpoint that the bubbles are much smaller and the graininess increases. Unless otherwise specified, the particle size of the powder A is the volume average (i.e., the volume average diameter).

The undiluted solution includes a medium for dissolving or dispersing the powder A therein. The medium is not particularly limited, and examples thereof include water, ethanol and polyhydric alcohols. Examples of polyhydric alcohols include, but are not limited to, 1,3-butylene glycol, dipropylene glycol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, Glycerin, polyethylene glycol, and the like. The content of the medium in 100% by mass of the undiluted solution is not particularly limited, but is preferably 10.0 to 95.0% by mass, more preferably 30.0 to 93.0% by mass, and further preferably 50.0 to 90.0% by mass. The medium may be of only one type, or two or more types may be used.

The surfactant may or may not be contained in the undiluted solution. In the present invention, it is possible to form an aerosol foam even if the surfactant (in particular, anionic surfactant, nonionic surfactant, amphoteric surfactant) is not contained in the stock solution or even if the content of the surfactant is very small , Which is one of the characteristics of the present invention. Examples of the surfactant include known surfactants such as anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants. The surfactant may be used alone, or two or more surfactants may be used.

Examples of the surfactant include, but are not limited to, higher fatty acid salts, alkylbenzene sulfonic acid salts,? -Olefin sulfonic acid salts, alkane sulfonic acid salts,? -Sulfo fatty acid ester salts, monoalkyl phosphoric acid ester salts, acyl-L - anionic surfactants such as glutamate; Nonionic surfactants such as polyoxyalkylene alkyl ethers, fatty acid mono- or dialkanolamides, polyoxyalkylene block polymers, and glycerin fatty acid esters; Cationic surfactants such as quaternary ammonium salts; And amphoteric surfactants such as carbobetaine, sulfobetaine, imidazolinium betaine, hydroxybetaine, fatty acid amide betaine, and the like.

The content of the surfactant in the undiluted solution is not particularly limited, but from the viewpoint of preventing stickiness, it is preferable that the content of the surfactant is small. In particular, the total amount of the content of the anionic surfactant, the content of the nonionic surfactant, and the content of the amphoteric surfactant in the undiluted solution is preferably less than 0.5% by mass, more preferably 0.1% by mass or less 0.01% by mass or less, particularly preferably 0.005% by mass or less. On the other hand, the lower limit is preferably 0% by mass. By reducing the content of these three surfactants, it is possible to suppress, in addition to the above-mentioned effects, that the foaming cosmetic is applied to the skin and is prevented from being broken by sweating, . This is believed to be due to suppression of re-emulsification due to adhesion of moisture such as sweat by reducing the content of these three surfactants. The content of the cationic surfactant in the undiluted solution is preferably 0.5 mass% or less, more preferably 0.2 mass% or less, for example, 0.01 to 0.5 mass% (particularly 0.05 to 0.2 mass%) in 100 mass% It may be. The lower limit of the content may be 0% by mass. When two or more kinds of cationic surfactants are contained in the stock solution, the "content of the cationic surfactant" means the total amount of the contents of all types of cationic surfactants in the stock solution.

The undiluted solution preferably contains a water-soluble polymer (at least one water-soluble polymer) selected from the group consisting of a cellulose-based water-soluble polymer and a natural water-based water-soluble polymer. By including a water-soluble polymer, the stability of the foam is improved. In the present invention, when the content of the powder A is small (for example, 12.0 mass% or less), the stability of the foam tends to be relatively low. Therefore, In the case of reduction, it is particularly effective to add a water-soluble polymer.

Examples of the cellulose-based water-soluble polymer include methyl cellulose, ethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose and the like.

Examples of the natural gum-based water-soluble polymer include xanthan gum, gelatin, guar gum, carrageenan, pectin, locust bean gum and the like.

The water-soluble polymer may be used alone, or two or more kinds may be used.

The content of the water-soluble polymer in 100 mass% of the undiluted solution is not particularly limited, but is preferably 0.005 mass% or more, and more preferably 0.01 mass% or more, from the viewpoint of further improving the stability of the foam. On the other hand, from the viewpoint of further reducing stickiness, the amount of the water-soluble polymer is preferably 0.3 mass% or less, more preferably 0.25 mass% or less, in 100 mass% of the undiluted solution. In the case where two or more water-soluble polymers are contained in the stock solution, the "content of the water-soluble polymer" means the total amount of the contents of all kinds of water-soluble polymers in the stock solution.

The stock solution is not particularly limited, but may include powder A, a medium, a component other than a surfactant or a water-soluble polymer (other components). For example, fragrances; Silicone oils such as cyclopentasiloxane, hydrogendimethicone, caprylylmethicone, methylphenylpolysiloxane and dimethicone; Fatty acid esters such as isopropyl myristate, ethylhexyl palmitate and 2-ethylhexanoate; Sugar alcohols such as sorbitol and maltitol; Preservatives such as phenoxyethanol, octoxyglycerin and methylparaben; Cold agents such as menthol, menthyl glyceryl ether, camphor, peppermint oil; Anti-inflammatory agents such as dipotassium glycyrrhizinate and stearyl glycyrrhizinate; Plant extracts such as peony, peony, loquat, and aloe; Fungicides such as isopropylmethylphenol, triclosan and benzalkonium chloride; Limiting agents such as zinc paraphenosulfonate, chlorohydroxyaluminum, and alum; Viscosity-increasing polymers such as carboxyvinyl polymer; Antioxidants such as tocopherol and dibutylhydroxytoluene; Octyl methoxycinnamate, octyl methoxycinnamate, dimethoxybenzylidenedioxoimidazolidinepropionate octyl, diethylaminohydroxybenzoylhexylbenzoate, t-butylmethoxydibenzoylmethane, octyltriazone, 2-ethylhexyl paramethoxyacetic acid and the like Ultraviolet absorber; Chelating agents such as edetate; Whitening agents such as arbutin and ascorbic acid; Silica, talc, powder of nylon powder, or the like.

Examples of the injection agent include known injection agents such as air, nitrogen, carbon dioxide, nitrous oxide, and other gases (particularly, compressed gas); Liquefied gas such as liquefied petroleum gas (LPG), dimethyl ether (DME), isopentane, fluorocarbon and the like. As the jetting agent, only one species may be used, or two or more species may be used.

The aerosol container may be a well-known container, and is not particularly limited.

In the aerosol container, the content of the jetting agent in the total amount of 100% by mass of the undiluted solution and the jetting agent is preferably 1.0% by mass or more, more preferably 2.0% by mass or more, and more preferably 3.0% by mass or more from the viewpoint of preventing liquefaction of the discharged liquid % Or more. Further, it is preferably 50.0 mass% or less, more preferably 20.0 mass% or less, and further preferably 10.0 mass% or less. When two or more kinds of injecting agents are used, the above " content of the injecting agent " means the total amount of all kinds of injecting agents.

The foam cosmetic of the present invention can be produced by a conventional method. For example, there can be mentioned a manufacturing method in which a stock solution is filled in an aerosol container, the container is clinically cleaned by an aerosol valve, a specified amount of injecting agent is charged into the container from the stem, and the injection button is mounted.

The internal pressure of the aerosol container of the foam cosmetic of the present invention can be appropriately adjusted according to the filling amount of the injecting agent. For example, at 25 占 폚, the internal pressure is preferably 0.10 to 0.50 MPa, and more preferably 0.15 to 0.39 MPa.

Example

Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples. The blending amount (content) means "% by mass" unless otherwise specified. In addition, all of the ingredients are expressed in pure amounts.

Test Example 1

160 g of purified water and 40 g of each powder described in Table 1 were mixed at 3000 rpm for 10 minutes using a Disper Mixer (DM) to prepare stock solutions 1 to 8.

Each of the raw liquid and the liquefied petroleum gas (LPG) as a jetting agent was filled in an aerosol container (capacity: about 100 ml) so that the mass ratio of the raw liquid and LPG became the raw liquid: LPG = 96: 4.

Subsequently, each foam cosmetic was shaken 5 times with a vertical width of 20 cm under normal temperature and normal pressure, and immediately thereafter, about 1 g of foam was discharged onto a black plastic plate. Then, the state of the formed foam was observed and evaluated according to the following evaluation criteria. The results are shown in Table 1.

(Evaluation Criteria of Formation State of Foam)

○ (Good): The bubble was formed, the shape of the bubble did not change after 1 minute, and the release of water was not confirmed.

× (poor): no bubbles were formed, or bubbles were partially formed, but the bubbles were not retained after one minute after the discharge.

[Table 1]

It can be seen from Table 1 that in the case of the foam cosmetic using the undiluted solution of 4 to 5, that is, the powder is the silicone-coated silica (undiluted solution 4) or the silica-coated silicone (undiluted solution 5), foam is formed even if the surfactant is not contained in the undiluted solution at all . In addition, in the foam cosmetic using the undiluted solution 4 and the undiluted solution 5, excellent foamy foam with smooth and smooth texture was formed. In addition, the foam formed in the foam cosmetic using the undiluted solution 4 and the undiluted solution 5 retained the shape of the foam even after a lapse of one minute, and the so-called bubble-keeping foam excellent in stability over time was excellent.

The average particle diameter of each powder in Table 1 is a value based on the volume average.

Examples 1 to 4 and Comparative Example 1

According to the prescription shown in Table 2, each component was mixed using a Disper Mixer (DM) at 3000 rpm for 10 minutes to prepare a stock solution (about 200 g).

LPG as a raw liquid and a propellant was filled in an aerosol container (volume: about 100 ml) so that the mass ratio of the raw liquid and LPG became the raw liquid: LPG = 96: 4 to prepare each foam cosmetic.

In Table 2, the total amount of each component in the stock solution is 100% by mass.

The cosmetic formulations obtained in Examples 1 to 8 and Comparative Examples 1 and 2 were evaluated as follows. The evaluation results are shown in Table 2.

(1) the quality of the froth, stability of the froth

Each foam cosmetic was shaken 5 times at a vertical width of 20 cm under normal temperature and normal pressure, and immediately thereafter, about 1 g of foam was discharged onto a black plastic plate. Then, the quality of the formed foam and the stability of the foam were observed and evaluated based on the following criteria.

(Evaluation criteria of foam quality)

◎ (excellent): Very fine and smooth

○ (Good): Smooth and smooth

△ (usable): Slightly discolored

× (poor): The texture is very rough, the foam is turned off, or the foam is not formed

(Evaluation Criteria of Stability of Foam)

◎ (Excellent): The quality did not change even after 3 minutes after discharge.

○ (Good): The quality did not change even after 1 minute after discharge.

△ (usable): After one minute after the discharge, although the release of water was visible, the shape of the foam was maintained.

× (poor): No foam was formed, or the foam did not retain its shape after one minute after discharging the water immediately after discharging.

(2) A smooth feeling

Each foam cosmetic was shaken five times with a vertical width of 20 cm under normal temperature and normal pressure. Immediately thereafter, about 0.3 g of foam was discharged onto the back of the hand and rubbed by hand. Sensory evaluation was carried out based on the following criteria.

In addition, a feeling of smooth running means a low friction, a good slippery feeling, and a non-sticky, dry feeling.

(Evaluation standard of feeling which is smooth)

◎ (excellent): Feeling very smooth and smooth.

○ (Good): Feeling strong and smooth.

× (bad): I did not feel a sense of smoothness.

[Table 2]

As can be seen from the results in Table 2, the foam cosmetic (Example) of the present invention formed a smooth and smooth foam, and was also excellent in the stability of the foam. In addition, there was no tackiness, and it was a cosmetic product which can obtain a sense of smoothness by coating. On the other hand, when the content of the powder is less than 5% by mass (Comparative Example), the quality of the gel and the stability of the foam are lowered.

After the evaluation of the above (2), in any of the examples, stickiness was not felt on the back of the hands coated with the foam cosmetic.

In Examples 1, 5, and 6 after the evaluation of (2) above, no or almost no whitening was observed in the hands on which the foam cosmetic was applied. In Examples 2, 3, and 7, whitishness was somewhat visible, but the powder was in close contact with the skin, and even when it reached the application surface, no scattering occurred. On the other hand, in Examples 4 and 8, strong white turbidity, in which the powder was scattered, was observed when it came into contact with the application surface.

Further, about 40 g of the stock solution of the foam cosmetic of Example 6 was placed in a glass bottle having a capacity of 100 ml and stored under the conditions of 5 ° C, 25 ° C and 40 ° C, respectively. As a result, sedimentation and caking of the powder did not occur even after 2 months under any condition, and excellent storage stability was obtained.
