  In order to solve the above problems, the present invention provides (a) a crosslinked polyether-modified silicone represented by the following formula (I), (b) a dextrin fatty acid ester and / or an inulin fatty acid ester, and (c) an acrylamide-based thickening agent. A water-in-oil emulsified cosmetic containing an agent and (d) 10% by mass or more of powder is provided.

[In formula (I), k shows the integer of 3-20; m shows the integer of 10-200; n shows the number of 1.0-10.0. ]

  In the present invention, the component (a) is a paste-like polyether-modified silicone composition kneaded with silicone oil under a shearing force, and the component (a) and the silicone oil in the composition The above-mentioned water-in-oil emulsified cosmetic is provided in which the kneaded product is a ratio of 10 to 10000 parts by mass of silicone oil with respect to 100 parts by mass of component (a).

  In the present invention, the component (c) is vinylpyrrolidone / 2-acrylamido-2-methylpropanesulfonic acid copolymer, dimethylacrylamide / 2-acrylamido-2-methylpropanesulfonic acid copolymer, acrylamide / acrylic acid / 2. Acrylamide-2-methylpropanesulfonic acid copolymer, mixture of polyacrylamide and polyacrylic acid, acrylic acid / 2-acrylamido-2-methylpropanesulfonic acid copolymer, acrylamide / 2-acrylamido-2-methylpropanesulfone Among acid copolymers, polyacrylamides, acrylamide / acrylic acid copolymers, 2-acrylamido-2-methylpropanesulfonic acid homopolymers, and vinylformamide / 2-acrylamido-2-methylpropanesulfonic acid copolymers Is one or more members selected to provide the water-in-oil emulsified cosmetic.

  According to the present invention, in a water-in-oil emulsification system containing 10% by mass or more of a powder, there is provided a water-in-oil emulsification cosmetic that is light in spreading, has a fresh feeling of use, and has excellent powder dispersibility and stability over time. The

  Hereinafter, the present invention will be described in detail.

  The crosslinked polyether-modified silicone as the component (a) is represented by the following formula (I).

[In formula (I), k shows the integer of 3-20; m shows the integer of 10-200; n shows the number of 1.0-10.0. ]
It is represented by

  The component (a) is a polymer obtained by crosslinking methylhydrogenpolysiloxane with diallyl polyethers at both ends.

  As the component (a), it is preferable to use a paste-like polyether-modified silicone composition that has been kneaded with a silicone oil under a shearing force in advance. You may mix | blend each as a component. Moreover, depending on the case, it is also possible to knead | mix the whole cosmetics, after mix | blending (a) component and silicone oil with another cosmetics component etc.

  In the above formula (I), when k is less than 3, when the component (a) is kneaded with silicone oil, the resulting paste-like composition has poor water emulsifiability, whereas when k exceeds 20. The swelling property of the component (a) into silicone oil is not sufficient.

  Moreover, when m is less than 10, the component (a) does not swell sufficiently with respect to the silicone oil. On the other hand, when m exceeds 200, the resulting paste-like composition has poor water emulsifiability.

  Further, when n is less than 1.0, a three-dimensional structure cannot be formed, and even when kneaded with silicone oil, it does not become a paste-like composition, and is inferior in water emulsifiability, If it exceeds 10.0, the crosslinking density of the three-dimensional structure becomes too high, so that even when kneaded with silicone oil, the silicone oil cannot be retained and a stable paste-like composition cannot be obtained.

  As said silicone oil, the low viscosity silicone oil whose viscosity in 25 degreeC is 100 mPa * s or less is used preferably. Examples of such low-viscosity silicone oils include chain silicone oils such as dimethylpolysiloxane (= dimethicone), methylphenylpolysiloxane, diethylpolysiloxane, ethylmethylpolysiloxane, ethylphenylpolysiloxane, and hexamethylcyclotrisiloxane. And cyclic silicone oils such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and tetradecamethylcycloheptasiloxane. These silicone oils can be used alone or in combination of two or more.

  When knead | mixing and using said (a) component and silicone oil, these kneaded materials are 10-1000 mass parts of silicone oil with respect to 100 mass parts of (a) component, Preferably it is the ratio of 20-500 mass parts. What is obtained by using and kneading is preferable. If the amount of the component (a) is too small than the above-mentioned usage rate, it is difficult to maintain a stable and good gel structure, while if it is more than the above-mentioned usage rate, it tends to be heavy.

  The kneaded product of component (a) and silicone oil is sufficiently swollen by component (a) with silicone oil, both components are sufficiently mixed, and both the feel and appearance are smooth and form a paste. It means what kneaded to the extent. When the kneading treatment is insufficient, the component (a) is not sufficiently swollen by the low-viscosity silicone oil, the component (a) remains in the composition and the two components are not mixed, and the resulting composition Is not preferable because it is a non-uniform composition with a smooth feel and appearance.

  The kneading treatment can be performed by, for example, a three-roll mill, a two-roll mill, a sand grinder, a colloid mill, or a Gaurin homogenizer, and a method using a three-roll mill is particularly preferable.

  Since the component (a) has a good swelling property with respect to the silicone oil, a paste-like uniform composition can be obtained by kneading with the silicone oil. It is possible to stably disperse powders, pigments and the like having a difference in specific gravity without settling, and water can be easily dispersed without using a surfactant.

  As the kneaded product of the component (a) and the silicone oil, a commercially available product can be used. As a commercially available product, for example, “KSG-210” (Shin-Etsu), which is a kneaded product containing 20 to 30% by mass of (dimethicone / (PEG-10 / 15)) crosspolymer and 70 to 80% by mass of dimethicone (solvent).
