BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition which is excellent in touch and long-lasting effect of cosmetics and also in the effect of hiding fine wrinkles. More specifically, the present invention relates to a cosmetic composition which is excellent in touch and long-lasting effect of cosmetics and also in the effect of hiding fine wrinkles by blending a grinding solution obtained by previously grinding a silicone resin powder.

2. Description of the Related Art Conventionally, JP-A-2-243612 and JP-A-7-533 have been proposed.
Japanese Patent No. 33, Japanese Patent Publication No. 4-66446, Japanese Patent Publication No. 6-
It is known from Japanese Patent Publication No. 51614 that blending various silicon-containing resin powders into a liquid cosmetic composition as it is improves properties such as touch and moisture retention.

These silicon-containing resin powders are not uniformly dispersed when they are crushed in a preparation using a device having a weak crushing force such as a homomixer, but some powders are aggregated. Often present in the form of secondary aggregates.

On the other hand, Japanese Patent Publication No. 6-55897 discloses a technique relating to a paste-like silicone composition obtained by kneading a low-viscosity silicone oil and a silicone resin with a roll mill. In this case, the secondary agglomerates are roughly loosened, and the characteristic is that thickening is obtained. However, since this composition is intended for thickening, it is a technology that focuses on the presence or absence of bleeding properties of the low-viscosity silicone oil from the composition, and it is a technology that enables optical control depending on the presence state of the resin in the oil agent. Is not disclosed. In addition, since the resin in the paste is not composited, there is a problem that the application feeling when blending the cosmetic material becomes unclear. Further, according to the examples of the above publications, the amorphous particles having an average particle diameter of 100 to 500 μm and large particles are used, which is not suitable for optical control of controlling the refractive index of the pulverized system. It was Therefore, the present inventors have made an optical study on the pulverizing method of silicone resin powder and the cosmetic effect, and an object of the present invention is to obtain a cosmetic material having a fine wrinkle hiding effect and an excellent cosmetic effect sustainability.

Then, the present invention can be achieved by blending this with a cosmetic. That is, silicone resin
It was found that a cosmetic having a fine wrinkle hiding effect and a long-lasting cosmetic effect can be obtained while maintaining the feel of the powder .

[0006] More particularly, in a grinding solution, silicone

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below.

The silicone resin powder used in the present invention is
The average primary particle diameter of the resin powder by observation using an electron microscope, in the range of 0.1 to 30 [mu] m, is good Mashiku 0.
The feature is that it is 1 to 20 μm and contains a silicon atom. The particle size distribution of the resin may be narrow or wide. However, when the particle size distribution of 50 μm or more is large,
There is a problem that the hiding power of fine wrinkles is weakened. The shape may be spherical, irregular, lumpy, plate-like, needle-like or the like. Of these, spherical or spherical aggregates are most preferable for the purpose of the present invention.

[0014] as a silicone resin powder, silicone resin powder and the like that have been released from countries inside and outside of the silicone manufacturers, for example, Toshiba made of silicone toss Pearl series and manufactured by Dow Corning Toray Silicone Co. DOO refill series And so on. Among them, preparative refill series good preferable particularly as the silicone resin powder used in the present invention.

In the present invention, among the silicone resin powders, those having properties as an elastomer (for example, silicone elastic powder: the trefill series, etc.) which are easily subjected to plastic deformation are preferable.

[0016] As the silicone oil used in the present invention, the ring <br/> like silicone, a volatile linear silicone. Preferred examples of the cyclic silicone include octamethylcyclotetrasiloxane (hereinafter referred to as D4) and decamethylcyclopentasiloxane (hereinafter referred to as D5).

As the oil agent used in the present invention, conventionally known substances that can be used in cosmetics can be used. For example, higher alcohols such as stearyl alcohol, cetyl alcohol, isostearyl alcohol, lauryl alcohol, hexadecyl alcohol and octyldodecanol, polyhydric alcohols such as glycerin, polyethylene glycol, 1,3-butanediol, propylene glycol and malbitol, isostearic acid. ,stearic acid,

Of these, an oil agent that has a large blending ratio with conventional cosmetics and has little effect on the original formulation system when blending a pulverized solution.Ester oil, polyhydric alcohol, paraffins, organic UV absorbers that are liquid at room temperature. Is preferred. Further, in the present invention, it is possible to use only silicone oil as an oil agent.

In the present invention, the silicone resin powder is pulverized or ground in an oil agent containing silicone oil to obtain a pulverized solution. A wet pulverizer is preferably used as the pulverizing method. When a pulverizing medium is required for the wet pulverizer, the type is not limited, but from the viewpoint of safety, resins such as ceramics, alumina and polyacetal resin are preferable. Examples of wet pulverizers include, but are not limited to, Micros, Dynomill, Ongmill, paint conditioner, sand mill, ball mill and the like.
Further, in general, it is preferable to use a media mill such as a sand mill, a dyno mill, or a micros, which is excellent in productivity and cost.

In the present invention, sheet during the milling solution 100 parts by weight
The silicone resin powder is contained in an amount of 5 to 75 parts by weight . If the amount is less than 5 parts by weight, it is difficult to obtain the characteristics of the silicone resin powder because the amount of the silicone resin powder in the product system is small, and if it exceeds 75 parts by weight, the viscosity of the pulverized solution increases. Therefore, it tends to be difficult to mix and redisperse the product in the product system.

Further, when the concentration of the silicone resin powder in the grinding solution exceeds 30 parts by weight, the viscosity generally increases, so that the grinding efficiency decreases. In this case, an increase in viscosity can be suppressed by using a component or a surfactant having a surfactant effect such as polyether modified silicone or acrylic silicone.

The crushing conditions used in the present invention vary depending on the crushing efficiency and crushing ability of the crusher, but it is preferable that the original primary structure of the silicone resin powder is collapsed. Examples of the method for evaluating the “state in which the primary structure is broken” include the following methods.

[0022] comprises a silicone resin powder, a strong state which is not crushed by the force solution when observed by a scanning electron microscope sample stage applied 1000 times the magnification of a silicone
The average primary particle size of the emission resin powder was measured to obtain an average value performed by several viewing it. Let this average value be A. Then,
Similarly, the solution in which the ricone resin powder is crushed is observed. The average primary particle diameter at this time is defined as B. At this time, when the value of B / A is in the range of 0 to 0.9, the primary structure is broken. That is, in this state, the silicone resin powder is mechanically deformed,
It shows that the structure is changing. The B / A value of 0 means that the primary particles have been completely deformed and lost their original structure, that is, the particle structure is not recognized.

[0023] Here, for the purpose of hiding the fine lines, the value of B / A is preferably in the range of 0.3 to 0.9. Within this range, the effect of hiding fine wrinkles is high. When the value of B / A is in the range of 0 to 0.3, the local change in the refractive index in the pulverized solution is small, and light irregular refraction hardly occurs, so the hiding property of fine wrinkles decreases. Further, if the value of B / A exceeds 0.9, the resin dispersion becomes a mere resin dispersion solution, and the change in the structure referred to in the present invention is not recognized.

In the present invention, the method for evaluating the hiding property of fine wrinkles in the crushed solution is most preferably a method in which the product is actually used and visually judged. A container is coated with a uniform thickness of about 1 to 2 mm, and a laser beam having a wavelength in the visible region is irradiated on the container, and the state of irregular refraction can be evaluated from the state of obstruction of the straightness of the laser beam. For example, the value of B / A is 0.8
When a transparent pulverizing solution is used, the laser light is irregularly refracted by the pulverizing solution and does not form a clear image. On the other hand, when the B / A value is 0, even after passing through the pulverizing solution, Form a clear image. When this state is evaluated as an index, a result close to that in actual use can be obtained.

On the other hand, in case of using the cosmetic for the purpose of ultraviolet protective such as sunscreens pulverized solution of the present invention, as the value of B / A, it is preferably in the range of 0-0.4 . Since silicone resin powder is generally transparent to ultraviolet rays (transmits ultraviolet rays), ultraviolet rays penetrate into the inside of this resin structure, and in the case of cosmetics aiming for high SPF value and high PA value, Its performance often deteriorates. On the other hand, when the resin structure is completely broken, the ultraviolet protection components such as fine particle titanium oxide and organic ultraviolet absorber can exert a sufficient effect.

In the cosmetic of the present invention, it is preferable to add 0.5 to 99 parts by weight of the above pulverized solution to 100 parts by weight of the cosmetic, and more preferably 1 to 30 parts by weight.
Within this range, it is possible to sufficiently exhibit various characteristics of the silicone resin powder that is well dispersed by pulverization.

In the cosmetic of the present invention, in addition to the above-mentioned components, powders, oils, resins, surfactants, ultraviolet absorbers, fragrances, preservatives, bactericides, moisturizers, which are usually used in cosmetics, A viscous agent, a physiologically active ingredient, a solvent, salts, water, an antioxidant, a chelating agent, a neutralizing agent, a pH adjusting agent and the like can be added at the same time.
