Embodiments of the present invention will be described below. The powder component, which is the component (A) contained in the cosmetics for body care of the present invention, is not particularly limited as long as it is a powder component that can be used in general cosmetics.

The powder component preferably has a spherical or similar particle shape.
It is preferable that the thickness be in the range of about 1 to 30 μm. Such powder components include, for example, vegetable powders such as starch (rice, corn, potato, wheat); talc,
Karion, mica, sericite (sericite), muscovite, phlogopite, synthetic mica, phlogopite, biotite, lithia mica, permiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, silicate Magnesium silicate, strontium silicate, metal tungstate, magnesium, silica, zeolite, barium sulfate, calcined calcium sulfate (baked gypsum), calcium phosphate, fluoroapatite, hydroxyapatite,
Ceramic powder, metal soap (zinc myristate, calcium palmitate, aluminum stearate),
Inorganic powders such as boron nitride; polyamide resin powder (nylon powder), polyethylene powder, methyl methyl acrylate powder, polystyrene powder, copolymer resin powder of styrene and acrylic acid, benzoguanamine resin powder, polytetrafluoroethylene powder, cellulose Organic powders such as powders are exemplified.

In the body cosmetics of the present invention, one or more of these powder components can be appropriately selected and used, and preferably, vegetable powders such as starch (rice, corn, potato, wheat) are used. An inorganic powder such as talc, kaolin, silica and the like, and a copolymer resin powder, particularly preferably corn starch, silica, polyamide resin powder (nylon powder), polyethylene powder, polystyrene powder and polymethyl methacrylate powder.

The amount of the powder component of the component (A) is as follows:
The body cosmetic of the present invention should be appropriately selected according to the specific dosage form and the balance with other compounding components, and the like, and should not be particularly limited. On the other hand, 0.01 to 15.0% by weight is preferable.
It is preferably 0.1 to 10.0% by weight. If this amount is less than 0.01% by weight based on the total amount of body cosmetics,
There is a tendency for slippage when applied to the skin to be worsened, and it tends to be difficult to suppress stickiness that occurs when an oil or a humectant is added, which is not preferred. When the amount is more than 15.0% by weight based on the total amount of the body cosmetics, the tendency of the powder to remain strong when the body cosmetics is used is recognized. Since a phenomenon may be observed, it is not preferable, and furthermore, since floating or settling of the powder component in the product may cause a problem in product stability,
Not preferred.

The amino-modified or ammonium-modified high molecular silicone of the component (B) used in the present invention is represented by the general formula (1). In the amino-modified or ammonium-modified high molecular weight silicone represented by the general formula (1), examples of the divalent hydrocarbon group having 3 to 6 carbon atoms represented by R ⁴ include a propylene group, a tetramethylene group, Examples include a pentamethylene group and a hexamethylene group. Examples of the alkyl group having 1 to 4 carbon atoms represented by R ⁵ and R ⁶ include a methyl group, an ethyl group, a propyl group, an isopropyl group, and a butyl group. Examples of the halogen atom represented by A include a chlorine atom, a fluorine atom, an iodine atom, and a bromine atom.

In the amino-modified or ammonium-modified high molecular weight silicone (1), particularly, R ¹ is a methyl group, R
² is a methyl group or a hydroxyl group, and R ³ is-(CH ₂ ) ₃ N
_{H 2, - (CH 2)} 3 N (CH 3) 2 or - (CH _{2) 3}
It is preferably a substituent having an amino group or an ammonium group, represented by N ⁺ (CH ₃ ) ₃ Cl ⁻ .

As described above, in the amino-modified or ammonium-modified high molecular weight silicone (1), m +
n is 3,000 to 20,000, preferably 400
0 to 20,000. When m + n is less than 3000, the amino-modified or ammonium-modified high-molecular-weight silicone (1) becomes oily, and the smoothness of the skin after using a body cosmetic containing the same tends to be insufficient. If it exceeds 20,000, the amino-modified or ammonium-modified high molecular weight silicone (1) becomes difficult to dissolve in other raw materials such as silicone oil, and disadvantages in production are recognized. Also, n / m is 1/500 to
1/10000, preferably 1/500 to 1 /
2000. If this n / m exceeds 1/500, the content of amino groups or ammonium groups in the high-molecular-weight silicone will be too high, and a cross-linking reaction or the like will occur during production of the amino- or ammonium-modified high-molecular-weight silicone (1). Is unfavorable, since the side reaction of the product may occur and the odor of the raw material may increase in the product. On the other hand, n / m is
If it is less than 1/10000, the sustainability of the slippery feeling on the skin of the body cosmetic due to the addition of the amino-modified or ammonium-modified high molecular weight silicone (1) tends to be inferior, which is not preferred.

The amino-modified or ammonium-modified high molecular weight silicone (1) can be produced by a conventional method. That is, for example, γ-aminopropylmethyldiethoxysilane, cyclic dimethylpolysiloxane, and hexamethyldisiloxane can be produced by a polycondensation reaction under an alkali catalyst, but the production method is limited to this method. Of course it is not.
The amino-modified or ammonium-modified high-molecular-weight silicone (1) is in the form of a soft rubber, and by incorporating it into the body cosmetic of the present invention,
Even when used in a large amount or continuously used for a long time, it is possible to improve the slippery feeling of the skin after application of the body cosmetic without accompanying a sticky feeling on the skin.

These amino- or ammonia-modified silicones (1) can be used alone or in combination of two or more in the body cosmetics of the present invention. The compounding amount is to be appropriately selected according to the specific dosage form of the body cosmetic of the present invention and the balance with other compounding components and the like, and is not particularly limited, but generally, The content is preferably 0.01 to 10.0% by weight based on the total amount of the body cosmetic. If the amount is less than 0.01% by weight relative to the total amount of the body cosmetic, the smoothness when using the body cosmetic tends to be poor, which is not preferable. If the amount is more than 10.0% by weight based on the total weight of the body cosmetics, the feeling of use of the body cosmetics tends to be oily, accompanied by a feeling of film, and the feeling of use tends to be impaired. In addition to increasing the strength, the stability of the product itself often causes problems, which is not preferable.

When the amino-modified or ammonium-modified high molecular silicone (1) is blended in the body cosmetic of the present invention, it is preferable to dissolve it in a liquid oil before blending. May be separately dissolved in the system. This liquid oil is not particularly limited as long as it is a liquid oil usually blended in cosmetics,
For example, linear polysiloxanes such as dimethylpolysiloxane, methylphenylpolysiloxane and methylhydrogenpolysiloxane; silicone oils such as cyclic polysiloxane such as decamethylpolysiloxane, dodecamethylpolysiloxane and tetramethyltetrahydrogenpolysiloxane; Hydrocarbon oils typified by isoparaffin hydrocarbon oils and the like can be used as the liquid oil.

Thus, the powder component as the component (A) and the amino- or ammonium-modified high-molecular silicone (1) as the component (B) were combined and blended.
The body cosmetic of the present invention is a body cosmetic that has a good feeling of use without stickiness, imparts a smooth and slippery feeling to the skin after use, and can moisturize the skin.

The body cosmetic of the present invention is preferably
Even if it does not contain oil, it can provide moderate viscosity, good spreadability, and slip, but only a small amount of oil, one or more kinds, to the extent that stickiness does not occur. Can be further improved, and a smoother feel can be given to the skin. In addition, by blending an oil component, compatibility can be enhanced when blending other oil-soluble components.

A: No change is observed in dispersibility. ○: Almost no change is observed in dispersibility. Δ: Slight floating or sedimentation of powder is observed. ×: Floating or sedimentation of powder is remarkably observed.

Tables 1 and 2 show the compositions and evaluation results of the body cosmetics (emulsion composition: prepared by a conventional method) used in each test.

[0044]

[Table 1] As can be seen from Test Examples 1 and 2, if the emulsified composition does not contain glycerin, which is a humectant, the skin after using the test product is not very sticky, but the original moistness of body cosmetics It turns out that is not recognized.
However, when glycerin is added as a humectant,
Stickiness was felt on the skin after use, which was unsuitable as a body cosmetic.

The test product of Test Example 3 is obtained by adding silicone to the test product of Test Example 2. It has been found that the addition of silicone reduces the stickiness of the skin after use, improves the smoothness of use, and maintains the moist feeling. When the ammonium-modified polymer silicone was added to the test product of Test Example 3 (Test Example 4), the sticky feeling and the smooth feeling were further improved.

However, as can be seen from Test Example 6, when a large amount of the ammonium-modified high-molecular silicone is blended, the skin after use becomes too slippery and tends to be accompanied by a coating feeling, which is unsuitable for body cosmetics. Was. As is clear from Table 1, blending of the amino-modified polymer silicone and / or the ammonium-modified polymer silicone improves the smooth feeling of use, does not show a sticky feeling of use, and is suitable for body cosmetics. Feeling was recognized.

[0047]

[Table 2] As is clear from Table 2, the blending of the powder component (talc or corn starch) made the skin after using the body cosmetics moist, smooth and non-sticky. Further, the feeling after use was different from each test example (only modified polymer silicone) in Table 1. However, it has also been found that the blending of a large amount of the powder component causes a powdery feeling during use. That is, in Test Example 12 in which the powder component was blended at 20.0% by weight, the powder was inferior in dispersibility, and after the test product was applied, powder floating on the skin was observed.
