Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a clay mineral dispersion and a cosmetic containing a silicone derivative and a water-swellable clay mineral, which are industrially easy to produce, and which can be produced by dissolving or exuding oil. The present invention relates to a dispersion and a cosmetic which prevent separation and deterioration of appearance, have excellent storage stability, and further provide good after-use feeling and usability.

[0002]

2. Description of the Related Art
In cosmetics and cleaning compositions, silicone derivatives have been widely used in order to improve moist feeling and usability. However, there is a problem that the silicone derivative in the composition is not sufficiently dispersed and separated, and particularly in a solid cosmetic, the silicone derivative exudes to the surface and impairs the appearance.

In particular, various studies have been made to solve the problem of oil seepage in solid cosmetics, and an acrylic-silicone-based graft copolymer specific to low-viscosity silicone derivatives and a partially crosslinked organopolysiloxane polymer have been developed. For forming a gel by blending a product (Japanese Patent Laid-Open No. 2-2796)
No. 17) or a method containing a polyvalent metal salt of dialkyl phosphoric acid and a specific benzoate, melting point of 75 to 120 ° C.
(JP-A-7-149613) and the like. However, the effects were not sufficient in each case, and further improvement was required.

[0004] On the other hand, it is known that a water-swellable clay mineral is added to a cosmetic or detergent composition to improve the feeling of dryness on the skin. Therefore, by using a water-swellable clay mineral and a silicone derivative in combination, cosmetics that combine the moisturizing feeling of the skin and the good touch have been studied, but it is particularly difficult to disperse the water-swellable clay mineral in the presence of the silicone derivative. However, there is a problem that it cannot be easily produced industrially.

Accordingly, an object of the present invention is to provide a cosmetic containing a silicone derivative and a water-swellable clay mineral, which can be industrially easily produced, prevents the appearance of the cosmetic from deteriorating due to oil dissolution and oozing, and preserves the cosmetic. An object of the present invention is to provide a cosmetic composition which is excellent in stability and gives good post-use feeling and usability.

[0006]

Means for Solving the Problems In view of the above-mentioned conventional problems and the like, the present inventors have made intensive studies and found that when producing a cosmetic containing a silicone derivative and a water-swellable clay mineral,
After preparing a primary dispersion of water having the same amount or less as the water-swellable clay mineral and blending the remaining water, the dispersion of the clay mineral is blended, whereby industrial production is possible, and oil separation / separation is possible. The inventors have found that it is possible to obtain a cosmetic that prevents deterioration in appearance due to dissolution or bleeding, that has excellent storage stability, and that further provides a good feeling and usability, thereby completing the present invention.

That is, the present invention provides the following (1) to (4)
Exists. (1) A clay mineral dispersion produced by preparing a primary dispersion with a silicone derivative, a water-swellable clay mineral, and the same amount or less of water as the water-swellable clay mineral, and then mixing the remaining water. (2) Cosmetics containing the above clay mineral dispersion. (3) The silicone derivative is one of (A) silicones
The dispersion and the cosmetic as described above, wherein one or more kinds of silicone derivatives having a difference from the solubility parameter of the silicones of 1 or more and (B) the silicones are 1 or less. (4) A clay mineral dispersion prepared by preparing a primary dispersion with a silicone derivative, a water-swellable clay mineral, and the same amount or less of water as the water-swellable clay mineral, and then blending the remaining water. Production method.

[0008]

Embodiments of the present invention will be described below in detail. The “solubility parameter (SP value)” defined in the present invention (including Examples and Comparative Examples) refers to a value calculated from the following equation.

[0009]

(Equation 1)

[0010] The clay mineral dispersion of the present invention (hereinafter referred to as "dispersion") is prepared as a primary dispersion of a silicone derivative, a water-swellable clay mineral, and the same amount or less of water as the water-swellable clay mineral. After that, it is prepared by blending the remaining water.
In the dispersion of the present invention, a stable and good-touch dispersion can be obtained by forming a composite of the clay mineral and the silicone derivative. If the required amount of water is mixed at once without preparing a primary dispersion, the swelling of the clay mineral proceeds before forming a complex of the water-swellable clay mineral and the silicone derivative, and the clay mineral becomes Since it becomes a paste, it is difficult to form a dispersion. Also in the water mixing after the preparation of the primary dispersion, it is preferable to mix the water in a plurality of times, since a sharp increase in the viscosity of the dispersion can be suppressed.

The silicone derivative used in the dispersion and the cosmetic of the present invention is not particularly limited as long as it is generally used as a cosmetic. And Japanese Patent Application No. 11-246137.

(A) Dimethylpolysiloxane. Specifically, those commercially available under the trade name of dimethyl silicone oil manufactured by Toray Dow Corning Silicone Co., Ltd. shown in Table 1 below can be used. (B) Cyclic silicone. Specifically, those commercially available under the trade name of cyclic silicone oil manufactured by Dow Corning Toray Silicone Co., Ltd. shown in Table 1 below can be used. (C) Methylphenyl polysiloxane. Specifically, those commercially available under the trade name of methylphenyl silicone oil manufactured by Toray Dow Corning Silicone Co., Ltd. shown in Table 1 below can be used.

[0013]

[Table 1]

[0014] The cosmetic of the present invention is characterized by containing the dispersion obtained by the above-mentioned production method. The cosmetic containing the dispersion of the present invention can have both a moist feel by the silicone derivative and a smooth feel by the clay mineral. Further, since the clay mineral and the silicone derivative form a complex, the silicone derivative can be stably present without being released in the cosmetic.

In particular, when the cosmetic is a solid cosmetic, since the clay mineral and the silicone derivative form a complex, the appearance of oil does not occur on the surface of the solid cosmetic to impair the appearance, and the cosmetic is stable. In addition, it is possible to obtain a solid cosmetic having a good feeling in use.

As the silicone derivative used in the dispersion and the cosmetic in the present invention, one or more of the above silicone derivatives can be used. In particular, two or more silicone derivatives having a difference in solubility parameter of 1 or less are used. It is preferable to use a combination of, particularly, polyether modified silicone and dimethyl silicone oil,
The difference in solubility parameter between the polyether-modified silicone and the cyclic silicone oil, and between the polyether-modified silicone and the methylphenyl silicone oil is 1
The following combinations are preferred. When the combination of the above-mentioned silicone derivatives exceeds 1 in the solubility parameter difference, when a dispersion is prepared by mixing and dispersing the water-swellable clay mineral and water, a good complex of the silicone derivative and the clay mineral is formed. And the dispersion stability of the clay mineral decreases, which is not preferable. In addition, the solid cosmetic composition prepared using this dispersion does not satisfy the effect of preventing the dissolution or exudation of oil components such as silicone derivatives.

The amount of the silicone derivative is 0.01 to 40% by mass relative to the total amount of the dispersion, preferably
It is blended so as to be 0.1 to 30% by mass. The amount of the silicone derivative is 0.01% based on the total amount of the dispersion.
If the amount is less than 10% by mass, the feeling of silicone will not be obtained, and the desired feeling of use such as the feeling after drying will not be obtained.
If the amount is more than 10% by mass, a good composite with the clay mineral cannot be formed, and the stability is lowered, which is not preferable.

Further, the difference between the solubility parameters is 1 or less.
When using a combination of two or more silicone derivatives,
In particular, when the polyether-modified silicone is used in combination with the silicone oils shown in Table 1, the blending amount of the polyether-modified silicone is based on the total amount of the dispersion.
0.1 to 30% by mass, preferably 0.5 to 20% by mass
It is blended so that If it is less than 0.1% by mass,
In some cases, the dispersion stability of the silicone cannot be ensured, and when it exceeds 30% by mass, the dispersion stability of the silicone is undesirably reduced.

The water-swellable clay mineral used in the dispersion and the cosmetic of the present invention is not particularly limited as long as it is a water-swellable clay mineral that can be generally used in cosmetics. Products, purified products of natural products, products obtained by modifying natural swelling properties, or products synthesized.
Water-swellable clay minerals contain exchangeable ions that hydrate and capture water molecules between layers, and exhibit properties such as swelling, adsorption, binding, suspension, and viscosity. . Above all, a water-swellable clay mineral having a swelling power of 20 mL / 2 g or more is particularly preferable from the viewpoint of dispersion stability of silicone and clay mineral. Furthermore, the solid cosmetic composition prepared using the dispersion containing the water-swellable clay mineral having the above-mentioned swelling power is particularly effective for preventing the oil such as silicone from dissolving or exuding.

Here, the "swelling power" of the water-swellable clay mineral refers to the swelling volume (mL) of 2 g of the clay mineral according to the bentonite test method specified in the thirteenth revised Japanese Pharmacopoeia.
It is represented by Specifically, 2.0 g of a clay mineral was taken and placed in a 100 mL measuring cylinder containing 100 mL of water.
The apparent volume of the lump at the bottom of the vessel when left for 24 hours is read from a scale. When water is added to the clay mineral in ten portions, the next sample is added after most of the previously added sample is deposited.

Smectite group clay minerals such as natural or synthetic montmorillonite, beidellite, nontronite, saponite, sauconite, hectorite, stevensite having the above-mentioned swelling power, vermiculite, swellable synthetic fluoromica (Na type, Li (Synthetic mica) can be used. Further, a high metal ion-substituted clay mineral which has been subjected to an ion exchange reaction of the above clay mineral and further improved in swellability can be used. Smectite group, bentonite containing montmorillonite of the smectite group as a main component, and the like are particularly preferable from the viewpoint of further stabilizing silicone dispersion. In addition, the water-swellable clay mineral alone,
Alternatively, two or more kinds can be used in combination. The water-swellable clay mineral having the above-mentioned swelling power used in the dispersion and the cosmetic of the present invention is Polagel (manufactured by American Colloids), Laponite (manufactured by Nippon Silica Industry Co., Ltd.), Wengel (manufactured by Toyoshun Mining Co., Ltd.), Lucentite Commercially available products such as (Coop Chemical Co., Ltd.), Kunipia (Kunimine Kogyo Co., Ltd.), Benclay (Mizusawa Chemical Co., Ltd.) and Vegum (Vanderbilt Co., Ltd.) can be used.

Incidentally, those collected from nature contain non-swelling impurities such as calcite, tridymite, cristobalite, quartz, and various inorganic substances, which sediment or dissolve in the dispersion. Release of electrolytes, and may impair the appearance of the detergent and the dispersibility of the clay mineral. Therefore, when a water-swellable clay mineral having the above-mentioned properties collected from nature is used, 90% of the water-swellable component is used.
Above (less than 10% of non-swelling impurities), especially 95%
It is preferred that the content be as described above (less than 5% of non-swellable impurities).

In the dispersion and the cosmetic of the present invention, the compounding amount of the water-swellable clay mineral having the above characteristics is 0.1 to 20% by mass, preferably 0.5 to 10% by mass based on the total amount of the dispersion. It is blended so that If the compounding amount of the clay mineral is less than 0.1% by mass, the dispersion stability of the silicone derivative may not be secured, and even if the compounding amount exceeds 20% by mass, the stability improving effect does not change. In some cases, dispersibility may decrease, which is not preferable.

As the water used in the dispersion and the cosmetic of the present invention, purified water, ion-exchanged water and the like can be used. The water is blended in an amount of 30% by mass or more, preferably 50% by mass or more, based on the total amount of the dispersion. If the amount of water is less than 30% by mass, the viscosity of the dispersion may increase, and the productivity may decrease.

The dispersion of the present invention is not only excellent in stability, but also excellent in smoothness, smoothness and moistness after drying. The feeling after use can be further improved when blended into the ingredients. Examples of the oil component include mineral oils such as petrolatum, liquid paraffin, and petrolactam; synthetic oils such as fatty acid triglycerides and higher fatty acid esters; higher fatty acids such as isostearic acid, stearic acid, and behenic acid; lauryl alcohol, cetostearyl alcohol, and behenyl alcohol. Higher alcohols (especially C16-22); squalane, whale oil,
Animal oils such as sealing oil, cod liver, tallow, beeswax, etc .; No.

The amount of the oil is 0.01 to 30% by mass, preferably 0.5 to 20% by mass, based on the total amount of the dispersion.
It is blended so as to be mass%. If the amount of the oil component is less than 0.01% by mass relative to the total amount of the dispersion, the feeling such as a moist feeling is not improved, and if it exceeds 30% by mass, a complex with a clay mineral is formed. It is not preferable because the dispersion stability of the silicone derivative and the oil component is lowered.

When the dispersion and the cosmetic of the present invention are mixed with a silicone derivative, an oil other than silicone, a water-swellable clay mineral and water to prepare a dispersion, the dispersion is not affected. Other optional components such as a water-soluble polymer compound, a water-insoluble powder such as a pigment, a dye, and a polyhydric alcohol can be appropriately compounded.

In the production method of the present invention, the dispersion is prepared by mixing a silicone derivative, an oil other than silicone, a water-swellable clay mineral and water, and if necessary, into a stirring tank (mixing tank) equipped with stirring blades. It is performed by charging the ingredients and mixing. The order of mixing the components is not particularly limited, but it is necessary to prepare a primary dispersion with a water-swellable clay mineral and the same amount or less of water in order to be able to be industrially prepared. As the apparatus for preparing the dispersion, a plurality of stirring blades that can be mixed with the shearing force, for example, a propeller,
A stirrer provided with a turbine, a disperser, etc. is desirable, and particularly preferably, an azimohomo mixer, a backflow mixer, a hybrid mixer, etc.

The dispersion of the present invention is particularly effective for the stability of oil in solid cosmetics. The solid cosmetic is not particularly limited to a base to be used, and is prepared as a solid, ointment, or gel composition. The types of cosmetics are not particularly limited, and foundations, lipsticks,
Blusher, eyeshadow, eyeliner, eyebrow, antiperspirant, tics, toilet soap and the like. Examples of the shape include powder, stick, paste, and pencil. Examples of the molding method include solidification by cooling in a mold, granulation, press pressing, kneading, and the like.

In the preparation of the solid cosmetic, the manner of mixing and dispersing the dispersion of the present invention with other solid cosmetic ingredients is not particularly limited. For example, an embodiment in which a dispersion liquid and other solid cosmetic ingredients are sequentially added to a stirring tank (mixing tank) equipped with stirring blades to mix and disperse the dispersion liquid, and a form in which the dispersion liquid is dried to be contained in a solid cosmetic. Is possible. The method for drying the dispersion is not particularly limited, and examples thereof include heating, spray drying, and roll kneading.

The apparatus for preparing the above-mentioned solid cosmetics includes:
Although not particularly limited, a stirring device, a kneading device, and the like can be used. As the stirrer, a stirrer equipped with a plurality of stirring blades capable of mixing with the shear force as a whole, for example, a propeller, a turbine, a disperser, or the like is desirable. Examples of the kneading device include a wheel type, a ball type, a blade type, and a roll type.

[0032] The dispersion of the present invention can be used, among solid cosmetics,
In particular, bar soap has a large effect of preventing oil seepage. When blended in a solid soap, the raw material of the fatty acid salt as the main component of the soap paste is not particularly limited, and any of a fat, a fatty acid, and a methyl ester may be used.
The alkali agent is not particularly limited, either caustic soda or caustic potassium may be used. Therefore, the production method may be any of the saponification method, the neutralization method, and the ester saponification method. Optional components such as a fatty acid, a polyhydric alcohol, and an antioxidant are further added to the thus obtained fatty acid salt to prepare a soap paste having a water content of about 30%.

The method for producing the solid soap is not particularly limited. For example, there is a method of kneading and shaping after adding an optional component to a soap base (water content of about 10%) obtained by drying a soap paste, a method of press-molding a soap base using a tableting machine, etc. After adding the ingredients and mixing them evenly,
Frame kneading, in which the material is poured into a mold, cooled, and solidified. At this time, a method of drying the soap paste to prepare a soap base is arbitrarily selected from ordinary methods. In the frame kneading, the cooled and solidified product may or may not be dried under a constant environment. The method of including the dispersion of the present invention in the solid soap is not particularly limited, for example, after mixing the soap paste and the dispersion, may be manufactured by kneading, or may be manufactured by frame kneading good. Alternatively, the dispersion may be dried and mixed with a soap base obtained by drying the soap paste.
