Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=4L]]However, in conventional cosmetics containing dichroic pigments, the edges of the applied part were not clear and a finished product with a sense of depth could not be obtained.

Means for Solving the Problems

[0005] The present inventors have found that an oil-based cosmetic using dichroic titanium lower oxide-coated particles together with an oil gelling agent, a semi-solid oil, and a non-volatile liquid oil has clear edges at the applied part and a finished product with a sense of depth can be obtained.

[0006] The present invention provides the following components (A), (B), (C) and (D): (A) An oil gelling agent, (B) A semi-solid oil having a melting point of 30 to 60°C, (C) A non-volatile liquid oil, (D) Low-order titanium oxide coated particles having dichroism with different appearance and interference colors. This relates to an oily cosmetic product containing [a specific ingredient]. [Effects of the Invention]

[0007] The oil-based cosmetic composition of the present invention provides a clear outline of the applied area, and in particular, when used as a lipstick, it clearly defines the contour of the lips. This results in a clearer image and a finish with a sense of depth. In other words, the oily cosmetic composition of the present invention comprises an oil gelling agent (A) and a semi-solid oil (B). By including this, a smooth coating film with a certain thickness is formed. The cosmetic has appropriate elasticity. By having this property, compared to low-elasticity agents that drip after application, the same amount applied... Even in this case, the coating film can be given thickness. Furthermore, it does not undergo spontaneous shape changes after coating. Compared to such highly elastic agents, leveling after application makes the thickness more uniform. It is easy to create a flat surface. For example, minor irregularities such as lip wrinkles can be filled in with cosmetics. It can be made smooth. This is also true for low-elasticity agents that drip after application. It only settles into wrinkles and does not easily become smooth. Thus, a smooth coating film with a certain thickness is not possible. The formation of this material results in the dichroism of the low-order titanium oxide coated particles in the planar portions and edges of the coating film. This makes it possible to show the effect effectively, and as mentioned above, the edges of the applied area become clearer, creating a sense of depth. A certain result can be achieved. [Modes for carrying out the invention]

[0009] Examples of the solid wax include waxes having a melting point of 61°C or higher. Waxes having a melting point of 61°C or higher exhibit a solid state at 25°C. In the present invention, the melting point is measured by the third method of the general test method described in the Cosmetic Raw Material Standards. That is, the sample is gradually heated to 90 - 92°C with stirring until it melts, heating is stopped, and the sample is cooled to a temperature 8 - 10°C higher than the melting point. Next, after cooling a thermometer (a thermometer for petroleum jelly melting point defined in Japanese Industrial Standard B7410) to 5°C, water is wiped off with filter paper, half of the mercury bulb is inserted into the sample, immediately removed, and held vertically and cooled. When the attached sample becomes turbid, it is immersed in water at a temperature of 16°C or lower for 5 minutes. Next, the thermometer is inserted into the sample, and a cork is used to fix the thermometer so that the distance between the lower end of the thermometer and the bottom of the test tube is 15 mm. This test tube is fixed in a 500 mL beaker filled with water at about 16°C so that the distance between the bottom of the test tube and the bottom of the beaker is 15 mm, and the bath temperature is heated so that it rises by 2°C per minute until it reaches 30°C. Then, heating is continued so that it rises by 1°C per minute, and the temperature when a drop of the sample separates from the thermometer is measured. This test is performed 3 times. When the difference in the measured values is less than 1°C, the average value is taken. When it is 1°C or more, it is measured 5 times and the average value is taken as the melting point.

Having dichroism, where the apparent color and interference color are different, means that it is particularly noticeable in the specular reflection direction with respect to the irradiated light. Interference colors and the visible colors from which interference colors are less noticeable are determined by one of the following factors: hue, saturation, or brightness. This refers to the differences mentioned above. Angle of incidence: The angle that the incident optical axis makes with respect to the normal to the coated surface of the low-order titanium oxide coated particles. Light receiving angle: The angle that the light receiving optical axis makes with respect to the normal of the coated surface (the side on the same side as the angle of incidence relative to the normal is positive, and the normal When the side opposite to the angle of incidence is considered negative, Specular reflection direction: For example, when the incident angle is 45°, the receiving angle is in the range of -70° to -20°. Directions where interference colors are difficult to see: For example, when the incident angle is 45°, the receiving angle is in the range of 20° to 70°. ru. In addition, typical interference pearl pigments are coated with titanium dioxide (uncolored white) as the outermost layer. Therefore, the exterior color is white, whereas the low-grade titanium oxide coated particles are low-grade titanium oxide Since it is covered, the appearance color becomes a color different from white (colored other than white).

Among these, synthetic phlogopite is preferred from the viewpoint of less color shading. The sub-oxide titanium coating the plate-shaped particles has a composition represented by TiOx (1.0 < x < 2.0),

[0039] and is obtained, for example, by mixing titanium powder and titanium oxide and sintering this under reduced pressure to obtain a titanium / titanium oxide sintered product. Thus, the sub-oxide titanium-coated particles of component (D) in which sub-oxide titanium is coated on plate-shaped particles can adjust the film thickness of the sub-oxide titanium coating layer, and the color tones of the appearance color and the interference color ​​​It can be adjusted.

[0040] Furthermore, the low-grade titanium dioxide coated particles of component (D) clearly define the edges of the coated area and create a sense of depth. From the viewpoint of effectively achieving the desired finish, it is preferable that the average particle size be 2 μm or more, and 5 μm m or more is more preferable, 15 μm or more is even more preferable, 100 μm or less is preferable, 8 0 μm or less is more preferable, and 50 μm or less is even more preferable. Also, the average particle size of component (D) is... The diameter is preferably 2 to 100 μm, more preferably 5 to 80 μm, and 15 to 50 μm. m is even more preferable. In this invention, the average particle size is the integrated value of the particle size distribution obtained by the laser diffraction / scattering method. It is measured by the particle size at 0%. Specifically, ethanol is used as the dispersion medium, and a laser is used. The particle size distribution is measured using a diffraction scattering type particle size analyzer (for example, LA-920 manufactured by Horiba, Ltd.).

[0041] The appearance color and interference color of the low-order titanium oxide coated particles of component (D) are generally similar to the appearance of pearl pigments. A method for evaluating color and interference color, that is, a method for evaluating appearance color on a white background and interference color on a black background. It can be evaluated more effectively. Furthermore, the lower titanium oxide coated particles of component (D) have an appearance color on a white background, and on a black background... Colors darker than the interference color are preferable because they can effectively create a sense of depth and three-dimensionality. The brightness of the appearance color and interference color can be expressed in terms of lightness L* measured using a colorimeter, and the number A higher value indicates a brighter color. The lightness L* of the appearance color and the interference color are compared. Then you can check which is brighter (or darker).

[0042] As for the lower-order titanium oxide coated particles of component (D), synthetic fluorphlogopite is (titanium / titanium oxide) A sintered coating is preferred, for example, SCALES COLOR M020Y-C SM, SCALES COLOR M020R-CSM, SCALES COLOR M 020B-CSM, SCALES COLOR M045R-CSM (both manufactured by Akaho Chemical Co., Ltd.) Commercially available products such as those manufactured by (or similar companies) can be used.

[0043] Component (D) can be used as one or a combination of two or more, and the content is as follows: From the perspective of clearly defining the edges and effectively creating a finish with a sense of depth, 0. Preferably 0.1% by mass or more, more preferably 0.1% by mass or more, and 0.5% by mass or less. The above is even more preferable, as it improves coating performance and results in a smooth coating film with a constant film thickness. From the perspective of making it easier to form and achieve a finish with a sense of depth, a mass of 30% or less is preferable. More preferably 22% by mass or less, and even more preferably 10% by mass or less. The content of (D) is preferably 0.01 to 30% by mass of the total composition, and preferably 0.1 to 22% by mass. Mass percent is more preferred, and 0.5 to 10 mass percent is even more preferred.

[0044] In the present invention, the mass ratio of component (D) to component (C), (D) / (C), is volatile. After the ingredients evaporate, it clearly defines the edges of the applied area and effectively creates a finish with a sense of depth. From this perspective, it is preferable that it be 0.0005 or higher, more preferably 0.001 or higher, and 0. A thickness of 0015 or more is even more preferable, and after the volatile components have evaporated, a smooth coating with a certain film thickness is formed. From the viewpoint of facilitating the formation of a fabric film, a value of 0.5 or less is preferred, and a value of 0.2 or less is more preferred. A value of 0.15 or less is even more preferable. Also, the mass ratio (D) of component (C) / (C) is preferably 0.0005 to 0.5, and more preferably 0.001 to 0.2. Furthermore, 0.0015 to 0.15 is even more preferable.

[0045] In the present invention, the mass of the total amount of components (A), (B), and (C) relative to component (D) The ratio ((A)+(B)+(C)) / (D) effectively creates a finish with a sense of depth. From this viewpoint, it is preferable that it be 0.02 or higher, more preferably 0.025 or higher, and 0.0 A ratio of 3 or more is even more preferable, as it clearly defines the edges of the coated area and effectively creates a finish with a sense of depth. From the perspective of representing this, a value of 1000 or less is preferable, a value of 900 or less is more preferable, and a value of 800 or less is preferable. Furthermore, the quality of the total amount of components (A), (B), and (C) relative to component (D) The ratio ((A)+(B)+(C)) / (D) is preferably between 0.02 and 1000. 0.025 to 900 is more preferable, and 0.03 to 800 is even more preferable.

[0048] Reference example (color measurement of pearl pigments) The pearl pigments shown in Table 1 were colorimetrically measured using the following method. The results are shown in Table 1. (Method for measuring the color of pearl pigments) For color measurement, each pearl pigment was measured on a 2.5 cm square white and black bios. Each sample was prepared by uniformly coating 1.5 mg of each substance onto a gin. Colorimetric analysis was performed using BYK-Gar. Using the DNER BYK-mac i multi-angle colorimeter, the appearance was measured. L*, a*, and b* were measured using a white background at 75° and a black background at -15° as the interference color. Note that the above "white background 75°" refers to the measurement conditions set on the device, and in reality, the white background The color of the sample applied to BioSkin is measured at an incident angle of 45° and a receiving angle of 30°. This refers to the above "black background -15°", which is a setting condition on the device side, and in reality, the black background bios This refers to measuring the color of a sample coated on a metal surface at an incident angle of 45° and a receiving angle of -60°. Color measurement was performed four times for each sample, and the average value was calculated and used for evaluation. This colorimetric value, L*, represents the brightness of a color; the larger the number, the brighter the color. This indicates that... Furthermore, as a method for evaluating the appearance color and interference color of pearl pigments, the appearance color is evaluated on a white background, and the interference color is evaluated on a black background. A method for evaluating color is commonly used. From the results in Table 1, the pearl pigments (1) to (4) have an appearance color lightness L* and an interference color lightness The L* value is smaller, and the apparent color on a white background is darker than the interference color on a black background. This was confirmed.
