Description

  The present invention relates to a light oily cosmetic that is excellent in gloss and adhesion of a coating film and has little stickiness and spreads easily.

2. Description of the Related Art Conventionally, a technique for blending a high-viscosity oil in order to improve the gloss and adhesion of a coating film in an oily cosmetic is known. However, the stickiness increases as the amount of the high-viscosity oil increases, and it may be difficult to obtain an oily cosmetic that is light in spread and has a good feel. Therefore, as a method for suppressing the stickiness of the oil agent, a technique for suppressing the stickiness and shine of the oil agent by blending powders such as silica and resin powder (for example, Patent Document 1), and a hydrocarbon containing isoparaffin and normal paraffin are used. There was a technique (for example, patent document 2) which suppresses stickiness by using the wax composition used together with polybutene having a specific molecular weight.
However, when powders such as silica and resin powder are blended, the effect of suppressing stickiness and shine of low-viscosity oils can be obtained, but the effect as expected when used in combination with high-viscosity oils such as polybutene cannot be obtained. In some cases, the stretch became heavy and the gloss was damaged. In addition, the technology that uses a wax composition consisting of hydrocarbons containing isoparaffins and normal paraffins together with polybutene of a specific molecular weight can reduce stickiness, but it does not increase stretchiness or oiliness. Sometimes happened.
As described above, with the existing technology, it is difficult to obtain an oily cosmetic material that is excellent in gloss and adhesion of the coating film and has little stickiness and light spread.

  On the other hand, easily disintegratable granulated silica particles obtained by granulating scaly silica are known as substances having good spreadability to the skin. When blending easily disintegratable granulated silica particles into cosmetics, it has been reported that silica particles gradually disintegrate due to physical friction during application, thereby improving the spreadability (e.g., patent document) 3). However, the characteristics by using the easily disintegratable granulated silica particles in combination with solid oil and / or oil gelling agent and high viscosity oil agent have not been known at all.

Formed as a constituent element of scaly silica having a primary particle thickness of 0.001 to 0.1 μm and a silanol group (SiOH) per specific surface area of 20 to 70 μmol / m ² used in the present invention. The granulated silica particles having an average particle diameter of 1 to 50 μm and easily disintegrating (herein sometimes abbreviated as “granulated silica particles of component (a)”) have high viscosity in the present invention. It suppresses stickiness without impairing the gloss and adhesion of the coating film possessed by the oil agent, and realizes a feeling of use that is light and spreads without oiliness. The granulated silica particles of component (a) can be produced by the method described in Document 3, and the described substances can be used.
The granulated silica particles of component (a) are composed of scaly silica having a primary particle thickness of 0.001 to 0.1 μm and a silanol group (SiOH) per specific surface area of 20 to 70 μmol / m ² , such as water. The slurry is made into a slurry with a solvent and is removed by a solvent removal in a granulation step such as spray drying. The average particle size is 1 to 50 μm and it is easily disintegratable.
Furthermore, the average secondary particle diameter of the flaky silica is 0.05 to 5 μm, and the aspect ratio is preferably 10 or more, more preferably 30 or more. In the present invention, the aspect ratio is a value obtained by dividing the major axis of the particle by the thickness, and measurement of the major axis and the thickness is performed using a scanning electron microscope (Real Surface View Microscope VE-7800 manufactured by KEYENCE). It can calculate by performing for each particle and using the average value.

The silanol group density of the scaly silica was measured by the thermogravimetric analysis method (Model 990 TGA-analyzer (manufactured by TA Instruments Japan) under the following conditions. 100 mg of silica was packed into a small quartz crucible and placed in a TGA-analyzer, the sample was heated to 120 ° at 10 ° C./min while dry nitrogen gas was passed through the heating chamber at a flow rate of 50 ml / min. The adsorbed water was physically removed from the silica surface, and the sample was maintained at 120 ° C. until weight loss could no longer be observed, then the temperature was increased to 300 ° C. at the same heating rate as before and kept constant. This temperature was maintained until a weight of 5 was reached The same procedure was repeated at 500 ° C., 700 ° C., 900 ° C., 1050 ° C., and 1200 ° C. At each temperature, the characteristic weight loss The total silanol group concentration on the silica surface was calculated from the total weight percent loss up to 1200 ° C. following the drying stage at 120 ° C. The silanol group concentration was calculated by heating 2 moles of silanol groups by heating. This was done based on the assumption that it was bound to 1 mole of water (which was lost from the sample during the heat treatment), and the total silanol group concentration (μmol / m ² ) on the silica surface was calculated according to the following formula:

Silanol group concentration = W × 1111.1 / SA
