Technical Field

The present invention relates to a titanium dioxide powder and a powder cosmetic containing the same, and more particularly to a powder cosmetic which is excellent in makeup and usability and has an excellent function of allowing light in a long wavelength region to pass therethrough (red light selective transmission function) while maintaining a covering power.

Background

Titanium dioxide has a high refractive index and is excellent in whiteness, hiding power, and coloring power, and thus is widely used as a white pigment for paints, plastics, and the like. Further, titanium dioxide is used as a substance for shielding ultraviolet rays, as an ultraviolet absorber or an ultraviolet shielding agent, and also used for cosmetics, catalysts, and the like by controlling the particle diameter or the photoactivity thereof, and thus, research and development have been actively carried out in these applications in recent years.

It is known that titanium dioxide powder having an apparent specific average particle diameter, which is formed of spherical particles of titanium dioxide having a specific average primary particle diameter in the form of a chlorella (Marimo) formed of a large number of titanium dioxide particles, is used in cosmetics as a functional material capable of imparting good smoothness and excellent light resistance, which have not been obtained with conventional titanium dioxide (patent document 1).

It is also known that the content of 1 to 15 mass% of the particles has an average particle diameter of 0.2 to 0.4μm and an average friction coefficient (MIU value) of 0.4 to 0.6A lip cosmetic comprising aggregated particles of rutile titanium oxide and 1 to 40% by mass of a semisolid oil component, which is glossy, suppresses the appearance of lip marks from becoming conspicuous, and has excellent long-lasting makeup properties (patent document 2).

Further, it is known that natural makeup can be achieved by blending a color material having a small absorption rate even for light having a long wavelength side of a visible light region (wavelength of 630 to 700nm) as a color material for cosmetics to make the light transmittance inside the skin close to that of makeup-free skin (patent document 3).

As such, as titanium dioxide for improving the transmittance of light on the long wavelength side of light, the following rutile-type titanium oxide has been known: the particles are in the form of rod-like particles which are oriented and agglomerated, the particles are oriented and agglomerated and have an apparent average major axis length of 80 to 300nm, the particles oriented and agglomerated have an apparent average minor axis length of 30 to 150nm, an apparent average axial ratio of the apparent average major axis length/the apparent average minor axis length of 1.1 to 4, and a specific surface area of 120 to 180m²The rutile titanium oxide is in the form of short strands or straw bundles, and has high transparency and ultraviolet shielding ability (patent document 4).

However, since this titanium dioxide is an aggregate of rod-like particles and many voids are present in the secondary aggregate, the apparent refractive index is lowered, and the hiding power is insufficient when the titanium dioxide is actually blended in a cosmetic. In addition, since the focus is on the protection against ultraviolet rays, the apparent particle diameter of the secondary agglomerate is also less than 100nm, which is significantly smaller than the particle diameter based on Mie theory to maximize the scattering effect of titanium oxide, and this also becomes a factor of reducing the hiding power.

Solid Powder cosmetics represented by Powder Foundation (Powder Foundation) are cosmetics obtained by adding an oil component as a binder to a Powder component, mixing the mixture, and filling the mixture in a container to mold the mixture. The powder component is mainly composed of an inorganic pigment, an organic pigment, and a resin powder, and the pigment is further classified into a color/pearl () pigment for adjusting color tone or gloss and an extender pigment other than the color/pearl () pigment. The extender pigment is typically a plate-like powder such as talc, mica, kaolin, etc., and occupies most of the powder components, and has a large influence on the moldability, adhesion, usability, etc. of the cosmetic. Further, by adding a characteristic extender pigment such as boron nitride, synthetic fluorophlogopite, barium sulfate to these basic extender pigments, the powder cosmetic is substantially characterized.

Among them, boron nitride is a highly demanded component because it has lubricity and imparts appropriate hiding power and comfortable adhesion to cosmetics.

In conventional titanium dioxide, although the hiding power of spots or the like on the skin is high, on the contrary, when a large amount of titanium dioxide is blended in order to increase the hiding power, unnatural makeup is formed, and unevenness on the skin may be more conspicuous than makeup-free skin.

Under such circumstances, it has been desired to develop a powder cosmetic which is obtained by blending boron nitride and another plate-like layered silicate, has excellent usability and uniform makeup, and forms a natural makeup when applied to the skin.

Detailed Description

The titanium dioxide powder of the present invention is characterized in that: the titanium dioxide powder is obtained by firing titanium dioxide having acicular protrusions on the particle surface, which is obtained by aggregating rod-like or needle-like particles in a radial orientation, at 500 to 800 ℃, more preferably 550 to 750 ℃, and has an average crystallite diameter of 15 to 30nm as measured by an X-ray diffraction method, an apparent average particle diameter of 100nm or more and less than 500nm, more preferably 200 to 400nm, and a specific surface area of 10 to 30m²/g。

[ titanium dioxide for mother nucleus ]

The crystal form of titanium dioxide used for the mother nucleus has anatase type and rutile type due to the difference of crystal structures. Here, the crystal form of titanium dioxide used in the present invention is a rutile type having a high covering power because of its low photocatalytic activity and high refractive index.

The rutile type titanium dioxide used for the mother core is titanium dioxide having a red light-transmitting function. The apparent average particle diameter of the titanium dioxide used for the mother core is preferably 100nm or more and less than 500nm, and more preferably 200 to 400nm, from the viewpoint of achieving the covering power due to scattering of titanium dioxide and the excellent red transmittance function obtained in the present invention, considering that the shrinkage phenomenon usually occurs after firing.

As the shape of the rutile type titanium dioxide used for the mother core, there can be mentioned: cocoon-shaped, straw bundle-shaped, short strip-shaped, spherical, needle-shaped, rod-shaped and the like. In the present invention, rod-like or needle-like particles are preferably aggregated in a radial orientation and have a shape having needle-like projections on the particle surface.

The specific surface area of the titanium dioxide used for the matrix is preferably 40 to 200m from the viewpoint of effectively increasing the apparent refractive index by firing²/g。

The rutile titanium dioxide used for the mother nucleus preferably has an average crystallite diameter of 1 to 25nm as measured by X-ray diffraction.

The titanium dioxide used for the parent nucleus may be a commercially available product. For example, ST700 series manufactured by titanium industries, Inc. can be mentioned. Among them, ST710 and the like can be mentioned.

[ titanium dioxide powder for use in the invention ]

The titanium dioxide powder of the present invention is obtained by firing titanium dioxide for the mother core.

The firing temperature is preferably the following temperature conditions depending on the apparatus for firing: the acicular projections projecting radially from the surface of the particles existing before firing are particles that are coagulated by firing, and the coagulation occurs by firing so that the voids existing between the acicular particles are reduced and the acicular particles are sintered to each other, and the average crystallite diameter measured by an X-ray diffraction method does not increase excessively. This makes it possible to achieve both sufficient hiding power and a red light selective transmission function.

The titanium dioxide powder used in the present invention is characterized in that: the powder is in the form of particles coagulated by firing, and acicular protrusions radially protruding from the surface of the particles existing before firing. Moreover, it is characterized in that: the ratio of the minor axis to the major axis (major axis/minor axis) of the particles is 1.0 or more and less than 2.5. More preferably 1.0 to 2.0.

The appropriate firing temperature varies depending on the firing apparatus, but when firing is performed in a muffle furnace or a rotary kiln, which is a common firing furnace, it is desirable to perform firing in the range of 500 to 800 ℃, more preferably 550 to 750 ℃. If the temperature is less than 500 ℃, voids existing before firing are not sufficiently reduced, so that the hiding power is insufficient, and if the temperature exceeds 800 ℃, sintering excessively proceeds, and the red light selective transmission function is lost.

The titanium dioxide of the present invention must have an average crystallite diameter of 15 to 30nm as measured by an X-ray diffraction method.

In the case where the crystallite diameter is less than 15nm, it is not preferable because a sufficient hiding power cannot be obtained. In addition, if the particle size exceeds 30nm, sintering proceeds, which is not preferable because the red light selective transmission function is sufficiently lost.

In addition, the titanium dioxide powder of the present invention is required to have an apparent average particle diameter of 100nm or more and less than 500nm, and more preferably 200 to 400nm, from the viewpoint of effectively realizing the covering power by scattering and the excellent red light transmission function.

The specific surface area of the titanium dioxide powder used in the present invention is an index showing the decrease in porosity and the progress of sintering of the obtained titanium oxide particles, and the specific surface area of the titanium dioxide powder forming the mother core after firing is preferably in the range of 8 to 50% as compared with that before firing (100%). More preferably 8 to 30%.

In addition, the specific surface area of the titanium dioxide powder needs to be 10-30 m²(ii) in terms of/g. If it is less than 10m²(g) loss of sufficient selective transmission of red light during sinteringIs not preferred in terms of function. In addition, if it exceeds 30m²The presence of voids is not preferable because sufficient hiding power cannot be achieved.

The titanium dioxide powder of the present invention may be subjected to surface treatment after firing. By performing the surface treatment, titanium dioxide having excellent usability while improving the viscosity, dispersibility in oil, and makeup retention accompanied by water repellency can be obtained.

Examples of the inorganic substance usable as the surface treatment agent include: hydrated oxides or oxides of metals containing aluminum, silicon, zinc, titanium, zirconium, iron, cerium, tin, and the like. The metal salt used in the method is not particularly limited.

Examples of the organic material that can be used as the surface treatment agent include, after surface treatment using a metal oxide or metal hydroxide such as aluminum hydroxide or aluminum oxide, for example, in order to impart lipophilicity: fatty acids such as stearic acid, oleic acid, isostearic acid, myristic acid, palmitic acid, and behenic acid; organosilicon compounds such as methylhydrogenpolysiloxanes, polydimethylsiloxanes, alkyl (C8-C18) trialkoxysilanes, amino-modified siloxanes and carboxyl-modified siloxanes; fluorine compounds such as perfluoroalkyl alkyl phosphates; amino acid derivatives such as dextrin myristate, dextrin palmitate, lauroyl lysine, and lauroyl glutamate.

These surface-treating agents are preferably used in an amount of 1 to 10% by mass based on the titanium dioxide powder because they have a high covering power.

The titanium dioxide powder used in the present invention can be widely blended in cosmetics, pigments, inks, paints, and the like.

The amount of titanium dioxide used in the present invention is 1 to 30% by mass, more preferably 5 to 15% by mass, based on the total weight of the powdery cosmetic composition. If the content is less than 1% by mass, the effect of the titanium dioxide of the present invention may not be obtained, and if the content exceeds 30% by mass, the makeup may be unnatural.

[ boron nitride ]

The boron nitride used in the present invention is not particularly limited as long as it is a boron nitride that is generally used in cosmetics, and commercially available products such as Ronaflair Boroneige SF-12 (manufactured by Merck), SHP-3, and SHP-6 (both manufactured by Shuitai iron alloy Co., Ltd.) can be used. For the purpose of improving dispersibility or adhesion, boron nitride surface-treated with silicone, fluorine compounds, metal soaps, oils, or the like can be used.

The amount of boron nitride to be blended in the present invention is 1 to 20% by mass, more preferably 3 to 15% by mass, based on the total weight of the powder cosmetic. If the amount is less than 1 mass%, the effect of boron nitride may not be obtained, and if the amount exceeds 20 mass%, the cosmetic appearance may be deteriorated.

[ plate-like layered silicate ]

In the present invention, a plate-like layered silicate such as synthetic fluorophlogopite iron, mica, synthetic fluorophlogopite, sericite, or the like is preferably used.

The synthetic iron fluorophlogopite and synthetic fluorophlogopite used in the present invention are not particularly limited as long as they are used in usual cosmetics, and the average particle diameter is preferably 2 to 20μm, more preferably 5 to 15μAnd m is selected. Examples of such synthetic fluorophlogopite iron include PDM-FE (manufactured by TOPY INDUSTRIAL CO., LTD.). Examples of the synthetic fluorophlogopite include PDM-5L and 10L (manufactured by TOPY industries, Ltd.). In order to improve dispersibility or adhesiveness, synthetic iron fluorophlogopite or synthetic fluorophlogopite surface-treated with silicone, fluorine compounds, metal soaps, oils, and the like can be used.

The amount of the plate-like layered silicate used in the present invention is 10 to 50% by mass, preferably 20 to 45% by mass, based on the total amount of the cosmetic. If the amount is less than 10% by mass, the makeup of the cosmetic may be deteriorated, and if the amount exceeds 50% by mass, the uniformity of the makeup may be deteriorated.

The aspect ratio of the plate-like layered silicate used in the present invention is more preferably in the range of 30 to 80.
