  As a method for obtaining the cation-modified clay mineral by treating the water-swellable clay mineral with a quaternary ammonium salt type cationic surfactant, for example, in the low boiling point solvent such as water, acetone or lower alcohol, It can be obtained by dispersing and stirring a water-swelling clay mineral and a quaternary ammonium salt type cationic surfactant and removing the low boiling point solvent. Moreover, it is also possible to mix a water-swellable clay mineral and a quaternary ammonium salt type cationic surfactant and to modify the organically in the formulation, and the product thus obtained can be suitably used. If desired, a quaternary ammonium salt type cationic surfactant and a nonionic surfactant may be used in combination.

  As a cation-modified clay mineral obtained by treating a water-swellable clay mineral with a quaternary ammonium salt type cationic surfactant, dimethyl distearyl ammonium hectorite (= quaternium-18 hectorite), dimethyl distearyl ammonium bentonite (= quaternium-18) Bentonite), dioctadecyldimethylammonium montmorillonite, octadecyldimethylbenzylammonium montmorillonite, dihexadecyldimethylammonium montmorillonite, and the like.

As such a dispersion, those described in Patent Document 5 which is a prior art document can be used. Moreover, a manufacturing method can also be performed by the manufacturing method of patent document 5. FIG.

  That is, the organically modified clay mineral has a layered structure having an average thickness of 2 μm or more, and usually forms an aggregate. Therefore, it is difficult to disperse in an oil with this layered structure. Therefore, in the oil component, the organically modified clay mineral is exfoliated by mechanical shearing force and / or impact force, and the average thickness is 0.1 μm or less and the average major axis is about 0.5 to 50 μm. Organic modified clay mineral particles having a plate-like particle structure are used. As a result, each plate-like particle of the organically modified clay mineral can be dispersed without substantially agglomerating in the oil.

  Specifically, it can be obtained as a dispersion having usually low viscosity and fluidity by the following treatment method. That is, the same volume of glass beads (or zirconia beads, etc.) having a diameter of about 1 mm is added to a mixture of a commercially available organically modified clay mineral (usually an aggregate having a layered structure having an average thickness of 2 μm or more) and an oil component. It is made into a thin piece by applying mechanical shearing force and / or impact force using a paint shaker, bead mill or the like. The dispersion once obtained can maintain a good dispersion state without agglomeration again in an oil phase such as silicone oil.

  The oil component for dispersing the organically modified clay mineral is not particularly limited, but is preferably an oil component that is liquid at room temperature as a whole, and silicone oil is particularly preferably used. Examples of silicone oils include, for example, chain polysiloxanes such as dimethylpolysiloxane and methylphenylpolysiloxane, cyclic polysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane.

From the viewpoint of the dispersibility of the organically modified clay mineral, the amount of the organically modified clay mineral dispersed in the dispersion is about 0.25 to 30% by mass of the organically modified clay mineral in the dispersion oil. preferable. By using this organically modified clay mineral dispersion in oil, compared to the case where the organically modified clay mineral is used as it is, the actual blending amount of the organically modified clay mineral in the cosmetic can be increased. The concealment effect can be exhibited more effectively, and also in terms of usability, a soft and smooth feeling of use like raw chocolate can be achieved more effectively due to a superior thickening effect. .

  (B) The compounding quantity (actual part) of a component is 2.5-8 mass% in this invention cosmetics whole quantity, Preferably it is 3-7 mass%. If it is less than 2.5% by mass, it is difficult to achieve the effects (for example, softness, smoothness, etc.) by blending component (b), while if it exceeds 8% by mass, the cosmetic becomes too hard and fills the container.
