Description

  The present invention relates to a cosmetic that is excellent in skin color adjustment effect and skin color tone concealing effect, and has excellent transparency and touch. In particular, the present invention relates to a cosmetic that achieves both a hiding power, a transparent feeling and a natural appearance by using two types of titanium oxides having different transmitted light.

Conventionally, many attempts have been made to optically hide skin tone troubles in cosmetics. In particular, in recent years, many attempts have been made to correct the color tone by using interference colors by using titanium mica. For example, Patent Document 1 discloses a “skin color adjustment composition that makes the dark red part of the skin inconspicuous, and a substance having transmitted reflection light having a maximum reflection peak (blue to green) at a wavelength of 400 to 550 nm. There is known a “red skin color adjusting composition” characterized by blending. This technology is a technology for blending a substance (titanium mica) that has a complementary color or a color gamut near the complementary color as transmitted light with respect to the skin color to be adjusted. There is a problem that the unique glossiness of titanium gives an unnatural impression, the amount of incorporation in the formulation is limited, and as a result, the target skin color correction effect is insufficient and consumers are There was a problem that caused a vicious circle of dissatisfaction.
Titanium oxide has usually been treated as a white pigment or a concealing material, but recently we have found that the color of transmitted light changes when the particle size of titanium oxide is changed as in Patent Document 2. However, it is unclear what kind of merit this effect gives to cosmetics.

Japanese Patent No. 3384628 JP 2000-191325 A

  Color is a very important factor in cosmetics, especially makeup cosmetics. In recent years, the use of transparent pigments has made cosmetic colors more complex than ever before. Among these, it has been found that coloring of transmitted light of titanium oxide, which has conventionally been considered only as a white pigment, affects the texture of cosmetics.

  Thus, as a result of intensive studies, the present inventors have found that the texture of cosmetics, in particular, the texture from evening to night can be improved by using the transmitted light of titanium oxide. In other words, by using two types of titanium oxides with different transmitted light colors, the skin color adjustment effect and the skin tone trouble concealment effect are excellent, but the transparency and feel are excellent. We found that cosmetics with a natural appearance can be obtained.

  That is, the basic configuration of the present invention is that the titanium oxide coated film is a titanium oxide in which the transmitted light looks green to blue when irradiated with incandescent light, and the transmitted light is red in the same way. There is a place where titanium is used in combination, and as a configuration for this, as the titanium oxide in which the transmitted light looks green to blue, the average primary particle diameter or the average aggregate particle diameter is in the range of 0.5 to 0.7 μm. As titanium oxide and titanium oxide in which transmitted light looks red, titanium oxide having an average primary particle diameter or an average aggregate particle diameter in the range of 0.1 to 0.3 μm is used in combination.

  Furthermore, the present invention includes blending one or more transparent pigments with the cosmetic.

  As described above, the present invention is excellent in transparency and touch while being excellent in skin color adjustment effect and skin tone trouble concealment effect by the combined use of two types of titanium oxides having different transmitted light colors. It is clear that cosmetics that achieve both a hiding power, transparency and a natural appearance can be obtained.

Hereinafter, the present invention will be described in detail.
The titanium oxide used in the present invention may be anatase type or rutile type. Examples of the shape of titanium oxide used in the present invention include a spherical shape, a substantially spherical shape, an indefinite shape, a spindle shape, a rod shape, and a plate shape. In particular, a spherical shape or a substantially spherical shape is preferable because the transmitted color is easily colored. The titanium oxide used in the present invention may be any of those that behave as primary particles and those that are granulated and behave as aggregated particles.

  In the cosmetic of the present invention, a titanium oxide-coated film is blended with titanium oxide whose transmitted light looks green to blue when irradiated with incandescent light, and titanium oxide whose transmitted light looks red by the same method. It is characterized by that. Note that the multiple light sources used in the present invention have a feature that the color change can be seen more clearly than in the case of a single light source. Although it is a manufacturing method of the film which coated the titanium oxide used by this invention, the method of disperse | distributing a titanium oxide to resin and applying this to a transparent resin film using an applicator etc. is preferable. As the resin, it is preferable to use a resin having little or no color such as nitrocellulose and polyester resin. If there is coloring, there is a problem that it is difficult to determine whether it is the optical effect of the pigment or the influence of the resin. In addition, since the resin alone causes poor dispersion due to viscosity problems, it is preferable to use a solvent such as hexane, acetone, lower alcohol, toluene, volatile silicone or the like in addition to the pigment and the resin. Examples of the dispersion method include a method using a disper, a method using a medium-type wet pulverizer, a roll mill, a paint shaker, and the like. A paint shaker is preferable because it is easy to operate. The film to be coated needs to be transparent, and examples thereof include a polyethylene terephthalate plate, a polystyrene plate, and a polypropylene plate, and a polyethylene terephthalate plate that is hardly deformed and is not easily affected by a solvent is most preferable. The most preferable coating condition is that the pigment concentration is 10% by mass and the coating thickness is 2 μm after the solvent is volatilized. Although the magnitude | size of a coating film is not specifically limited, The magnitude | size of B4 plate to A4 plate is moderate. As the incandescent lamp used in the present invention, an incandescent lamp having an output of 60 to 100 W is preferable because the color change is clear.

  Examples of the titanium oxide in which the transmitted light in the present invention looks green to blue include titanium oxide having an average primary particle diameter or an average aggregate particle diameter in the range of 0.5 to 0.7 μm. A preferable method for measuring the average primary particle size or the average aggregated particle size is measurement of the particle size by observation with an electron microscope. In addition, the particle size distribution may be sharp or broad, but sharpness is preferable because the transmission color becomes stronger when sharp.

The titanium oxide in which the transmitted light in the present invention looks red is titanium oxide having an average primary particle diameter or an average aggregate particle diameter in the range of 0.1 to 0.3 μm. The method for measuring the particle diameter is the same as described above.
An example of quantification of evaluation used in the present invention is as follows. Using a digital camera, the color of transmitted light is photographed under the same photographing conditions without using a flash, and the image is processed using image processing software ( Convert to color space coordinates (for example, CIEL * ab value of the International Commission on Illumination) using Adobe Photoshop, etc., quantify the shadow color, and select the most suitable pigment from that value Is mentioned.
The wavelength in the range where the transmitted light appears green to blue is a color having a maximum peak between wavelengths 400 to 600 nm (blue has a maximum peak at 400 to 500 nm and green has a maximum peak at 500 to 600 nm). The range where the transmitted light can be seen in red refers to the color having the maximum peak at a wavelength of 600 to 700 nm.

In the present invention, the color is measured according to the method described in JP-A No. 2000-191325.
Specifically, 1 g of a sample, 17.8 g of nitrocellulose (solid content 18.8% by mass) <sample / nitrocellulose solid content = 3/8 (weight ratio)>, and 60 g of glass beads were added to a glass bottle with a lid of 80 ml. The mixture was dispersed for 1 hour using a paint conditioner manufactured by Red Devil Co., Ltd. The obtained dispersion paste was applied to a polyethylene film with a bar coater (# 10) (film thickness of about 5 μm) and dried at room temperature for 30 minutes. The transmission spectrum at 350 to 8000 nm of the formed coating film was measured using a spectrophotometer (U-3300) manufactured by Hitachi, Ltd.

  These titanium oxides are preferably surface-treated. Examples of water repellent surface treatment include, for example, methylhydrogenpolysiloxane treatment, silicone resin treatment, silicone gum treatment, acrylic silicone treatment, organosiloxane treatment such as fluorinated silicone treatment, metal soap treatment such as zinc stearate treatment, Silane coupling agent treatment, silane treatment such as alkyl silane treatment, organic titanate treatment, organic aluminate treatment, perfluoroalkyl silane, perfluoroalkyl phosphate ester salt, fluorine compound treatment such as perfluoropolyether treatment, N-lauroyl Examples include amino acid treatment such as -L-lysine treatment, oil agent treatment such as squalane treatment, acrylic treatment such as alkyl acrylate treatment, and the like, and one or more of these can be used in combination. Examples of the hydrophilic surface treatment include agar treatment, deoxyribonucleic acid treatment, lecithin treatment, polyacrylic acid treatment, silica treatment, alumina treatment, zirconia treatment and the like. These pigments may or may not be highly dispersed.

  The blending amount of the titanium oxide in which the transmitted light used in the cosmetic of the present invention appears green to blue and the titanium oxide in which the transmitted light looks red is the total blending amount of these two types of titanium oxide with respect to the mass of the cosmetic. The range of 1-50 mass% is preferable as this, Especially preferably, 1-35 mass% is mentioned. When the blending amount of titanium oxide in this range is less than 1% by mass, it becomes insufficient for obtaining an optical effect, and when it exceeds 50% by mass, the color becomes too white even for concealer use. There is a problem that becomes unnatural.

  Next, the blending ratio of titanium oxide in which transmitted light looks green to blue and titanium oxide in which transmitted light looks red is preferable, but a range of 10:90 to 90:10 is preferable, and 50:50 to 90: is particularly preferable. There are 10 ranges. Within this range, there is an advantage that the desired optical effect can be easily obtained. Titanium oxide whose transmitted light looks green to blue has less hiding power per unit mass than titanium oxide whose transmitted light looks red, but within this range, it has a suitable hiding power for cosmetics. It can be secured.

  In the cosmetic of the present invention, it is preferable to use a transparent pigment. Transparent pigments include pigments that have a property that the whiteness is reduced to less than half when a dry pigment is mixed with oil.For example, organic pigments, sapphire, ruby, barium sulfate, calcium carbonate, silicic anhydride Inorganic compounds such as

  In the present invention, an organic pigment having particularly high transparency is preferred. In the present invention, the organic pigment refers to a pigment formed of an organic compound. For example, the organic powder includes polyamide powder, polyester powder, polyethylene powder, polypropylene powder, polystyrene powder, polyurethane powder, benzoguanamine powder, Polymethylbenzoguanamine powder, polytetrafluoroethylene powder, polymethyl methacrylate powder, cellulose powder, silk powder, nylon powder such as 12 nylon and 6 nylon, polyacryl powder, polyacryl elastomer, styrene / acrylic acid copolymer, divinylbenzene・ Styrene copolymer, vinyl resin, urea resin, phenol resin, fluorine resin, silicon resin, acrylic resin, melamine resin, epoxy resin, polycarbonate Bonate resin, microcrystalline fiber powder, starch powder, lauroyl lysine, etc., especially silicone resin, silicone elastomer spherical powder, polyalkylsilsesquioxane, cellulosic powder, nylon, polystyrene, polyethylene, polypropylene, acrylic One or more pigments selected from an acid powder, polyethylene terephthalate, N-acylated lysine, alginic acid powder, and alginate powder are preferred.

  These powders have a tendency to transmit visible light relatively, and are excellent in touch. The advantages of using a transparent pigment are described below. In the past, transparent pigments have not been used frequently in makeup cosmetics, such as foundations, and even if they are used, they have been used for touch adjustment. The foundation at that time (for example, 15 years ago) was mainly composed of inorganic extender pigments such as sericite, titanium oxide, and iron oxide, and the light reflected off the surface of the coating. Even if it was used, there was no effect because the transmitted color itself did not return to the surface from the coating film. These light-reflective preparations had a strong image of cosmetic appearance.

  However, with the recent trend of cosmetics, characteristics such as “natural” and “natural” are emphasized, and as a technique for that purpose, transparent pigments that transmit light to some extent are frequently used. It became so. When the transparent pigment is contained, not only the reflection of the light on the surface of the coating film but also the light scattered or diffracted inside the coating film appears on the surface. In this case, in terms of appearance, a coating film having an optical depth can be formed, and a texture closer to that of human skin can be provided. In the case of a decorative coating film designed in this way, light penetrates into the interior of the coating film, and there are components that return to the surface, so that the transmitted color of titanium oxide affects the texture of the decorative coating film. It was. Conversely, the use of such transparent pigments has created room for the transmission color of titanium oxide to be used.

  Further, in the cosmetic of the present invention, the transmitted light is used in combination with titanium oxide in which the transmitted light looks green to blue and titanium oxide in which the transmitted light looks red, but the transmitted light having a large particle size and excellent slipperiness is used. When combined with titanium oxide that looks green to blue and titanium oxide that shows red light with strong adhesion, the way the titanium oxide touches the skin is better than the conventional pigment-grade titanium oxide coating. There is a merit that a cosmetic with a smoother and even application feeling can be obtained.

Example 1
A foundation was prepared according to the formulation and manufacturing method shown in Table 1. As the titanium oxide in which the transmitted light looks green, a substantially spherical anatase-type titanium oxide (titanium oxide described in Example 1 of JP-A-2000-191325) having an average aggregate particle diameter of 0.7 μm is used, and the transmitted light becomes red. As visible titanium oxide, spherical rutile type titanium oxide having an average primary particle size of 0.2 μm was used. The former was treated with silica and then treated with octyl silylation, and the latter was treated with perfluoroalkyl phosphate ester salt. Further, plate-like barium sulfate and a silicone elastomer (Torefil E-508 manufactured by Toray Dow Corning) and silicone beads (GE Tospearl 145A manufactured by GE Toshiba Silicone) were used as transparent pigments.
In addition, the unit in a table | surface is the mass%.

Production Method Component A was mixed and ground using a mixer, while component B was mixed using a cradle, and then components A and B were mixed using a mixer. From that, the uniformly dissolved component C was added, and further mixed and pulverized. Next, the obtained mixture was passed through a mesh (60 mesh), and then cast into a metal pan using a mold to obtain a product.

(Comparative Example 1)
A product was obtained in the same manner as in Example 1 except that surface-treated titanium oxide (transmitted light: red) was used instead of surface-treated titanium oxide (transmitted light: green).

[Comparative Example 2]
In Example 1, instead of surface-treated titanium oxide (transmitted light: green), the average aggregated particle diameter is 0.3 μm, and the transmitted color is orange titanium oxide (the oxidation described in Example 3 of JP-A-2000-191325). A product was obtained in the same manner as in Example 1 except that titanium was used.

  Table 2 shows the evaluation results of Examples and Comparative Examples. The evaluation was conducted by using 5 panelists, and the products to be tested were applied half face by face, and the self-evaluation of the touch at the time of application and outside light entered from the west window at 4 pm and illuminated with a fluorescent lamp. Each person's visual evaluation of the panel's face in the room was scored from 0 to 5 points (0 points indicate poor evaluation, 5 points indicate good evaluation), and the average score of all panelists Evaluation results. Therefore, it shows that it is judged that it is excellent with respect to each evaluation item, so that a score is high.

From the results of Table 2, the examples of the present invention are superior in skin color adjustment effect and skin color trouble concealment effect as compared with the comparative example, but are excellent in transparency and touch, and have concealment power and transparency and naturalness. It can be seen that the external appearance is balanced.
