本発明は二酸化チタンの微粒子で被覆することにより、
紫外線遮へい効果を有する偏平状顔料に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a dish with fine particles of titanium dioxide.
This invention relates to a flat pigment that has an ultraviolet shielding effect.
従来日焼は止め化粧品には、有機系の紫外線吸収剤や酸
化チタン、酸化亜鉛等の無機粉体が使用されてきたが、
有機系の紫外線吸収剤は皮膚への安全性や使用する系で
の安定性等に問題があり、また酸化チタン等の無機粉体
は隠蔽力が大きく、皮膚に塗布した場合の着色力が強い
ため厚化粧の状態になり、自然な仕上がりが得られない
し、皮膚への付着力が強く、化粧品にした場合好ましい
感触が得られない等の問題があった。Traditionally, sunscreen cosmetics have used organic ultraviolet absorbers and inorganic powders such as titanium oxide and zinc oxide.
Organic UV absorbers have problems with their safety to the skin and stability in the system in which they are used, and inorganic powders such as titanium oxide have large hiding power and strong coloring power when applied to the skin. This results in heavy makeup, making it impossible to obtain a natural finish, and there are problems in that it has strong adhesion to the skin and does not give a pleasant feel when used as a cosmetic product.
一般に広（用いられている顔料用の酸化チタンにくらべ

く使われているが、粒径があまりにも小さいため分散が
やや困難であり、また通常の酸化チタン同様粒子の形状
が一定ではなく、皮膚への付着性が強すぎるために滑ら
かな伸びの感触が充分とはいい難い。Ultrafine particle titanium oxide with an average particle size of 10 to 50 μm has a smaller hiding power and coloring power than titanium oxide, which is generally used for pigments, and has an excellent UV shielding effect due to its large specific surface area. Recently, it has been widely used in place of titanium oxide, but its particle size is too small, making it somewhat difficult to disperse.Also, like regular titanium oxide, the shape of the particles is not constant, and its adhesion to the skin is too strong. It is difficult to say that the feeling of smooth stretching is sufficient.
伸びや感触を向上させる目的でマイカ、セリサイト等の
偏平状鉱物、ナイロン、ポリスチレン、エポキシ等の樹
脂球状体、酸化チタン、シリカ、アルミナ等の無機球状
体等が併用されるが、これらの顔料の粒径が超微粒子酸
化チタンの粒径と掘端に異なることや、粒子の形状、比
重等の差が原因で均一混合が非常にしに（い。Flat minerals such as mica and sericite, resin spheres such as nylon, polystyrene, and epoxy, and inorganic spheres such as titanium oxide, silica, and alumina are used in combination with these pigments to improve stretch and feel. Uniform mixing is extremely difficult due to the difference in grain size from that of ultrafine titanium oxide and differences in particle shape, specific gravity, etc.

被覆量において微粒子酸化チタンを被覆してなる紫外線
源へい顔料に関する。The present invention provides an ultraviolet light source in which the surface of an inorganic flat material with an average particle diameter of 0.5 to 1 ooμm is coated with fine titanium oxide particles at a coating amount that does not substantially produce a pearlescent appearance due to interference. Concerning pigments.

の干渉色が発現するように酸化チタン被覆層の厚みを調
整しである。Mica titanium, which has a pearlescent luster and is made by coating Niraho Hoshino Umaica with titanium dioxide, is often used in makeup cosmetics, etc., but the purpose of these products is to create a sense of brilliance, and the particle size of the mica used as the material, The thickness of the titanium oxide coating layer is adjusted so that silver color and other interference colors appear depending on the specific surface area.

覆量においても使用目的に応じ隠蔽力の大きい顔料と、
隠蔽力は小さいが透明感のある顔料とを得ることが可能
である。When using them in a sunscreen foundation,
It is rather inconvenient that a shiny feeling appears. Therefore, the ultraviolet source flat pigment according to the present invention is characterized in that the coating amount of fine particle titanium dioxide is set to a coating amount that does not substantially cause pearlescence or glitter due to interference. However, even at this coating amount, pigments with high hiding power can be used depending on the purpose of use.
Although the hiding power is low, it is possible to obtain a transparent pigment.

、紫外線源へい効果が増し、皮膚に対する被覆力を要求
される化粧品には好ましいが、透明感が要求されるよう
な製品には酸化チタンの被ｆｆ１ｆｆｌが少ないものが
通している。In other words, as the ff1ffl of titanium oxide increases, the hiding power and UV source shielding effect increases, which is preferable for cosmetics that require covering power on the skin, but for products that require transparency, the ff1ffl of titanium oxide increases. Few things are passing through.

の被ｒｉｌは、個々の場合について実験的に容易に定め
ることができる。The coating amount of fine particle titanium oxide, which does not substantially produce a pearlescent or glittering effect due to interference, cannot be determined unconditionally because it varies depending on the type and particle size of the inorganic flat material that is the base.
If the range in which the above-mentioned pearlescent or glittering feeling can be obtained for a specific inorganic flat material serving as a substrate is, for example, 30 to 50% by weight of the inorganic flat material as TiO2, in the present invention, TiO2 is 25% by weight or less and 50% by weight or less. Covered by weight% or more
, you can choose the amount. Therefore, the ril of particulate titanium oxide can be easily determined experimentally for each case.

。In the case of mica flat pigments that are thinly coated with titanium oxide on the surface of the ultraviolet ray source, when you look at the powder itself, there is a slight shine characteristic of mica, but when these are kneaded into liquid paraffin, etc., the refractive index of mica is approximately 1°5, it is transparent because its refractive index is close to that of liquid paraffin used as a medium, and the ultrafine titanium oxide precipitated on the mica surface has a particle size sufficiently small for the wavelength of visible light, so it is visible. Transmits light,
The result is a transparent finish. Also, those coated thickly with ultrafine titanium oxide particles have the same hiding power as regular titanium oxide, and are finished with almost no glitter.
従ってマイカ表面に屈折率の高い酸化チタンの層を形成
し、界面での光の反射、干渉を利用した真珠光沢を有す
る雲母チタンとはその機能が全く異なる。Therefore, its function is completely different from mica titanium, which forms a layer of titanium oxide with a high refractive index on the mica surface and has a pearlescent luster that utilizes light reflection and interference at the interface.
本発明による紫外線源へい偏平状顔料は、光輝感が出な
いので、日焼は止めファンデーションに主原料として多
量に添加しても光輝感が出す、偏平状であるので伸びや
感触も優れ、それ自身紫外線系へい効果を有するため、
通常紫外線系へい剤として用いる超微粒子酸化チタン等
の添加の必要がなく、また添加するとしても少量ですみ
伸びや感触を損なわない。The ultraviolet-source flat pigment according to the present invention does not give a glittering effect, so even if it is added in large quantities as a main ingredient to a foundation that prevents sunburn, it still produces a glittering effect. Because it has a UV-based protective effect,
There is no need to add ultrafine titanium oxide, which is normally used as an ultraviolet-based staining agent, and even if it is added, a small amount is enough and the spread and feel are not impaired.
二酸化チタンの被ｒｉ量の多い本発明の紫外線源へい偏
平状顔料を用いると適度な隠蔽力が出るため伸びや感触
を阻害する顔料用酸化チタンの添加の必要がなく、また
添加するとしても少量ですむ。If the flat pigment of the present invention is used as the ultraviolet source of the present invention, which has a large amount of titanium dioxide, it will have a moderate hiding power, so there is no need to add titanium oxide for pigments, which inhibits spread and feel, and even if it is added, it will only be small. That's fine.
超微粒子酸化チタンの欠点の一つとして、超微粒子であ
るがゆえに分散がやや困難であることがあげられるが、
本発明による紫外線源へい偏平状顔料は、粒径が大きい
ため分散も容易であるし、超微粒子酸化チタンが素材と
なる無機偏平状物質上に凝集することなく、あらかじめ
分散した格好で析出しているために分散効率に起因する
紫外線遮へい効果の向上が期待できる。One of the drawbacks of ultrafine titanium oxide is that it is somewhat difficult to disperse because it is an ultrafine particle.
The ultraviolet source flat pigment according to the present invention has a large particle size, so it is easy to disperse, and the ultrafine titanium oxide particles are precipitated in a dispersed state without agglomerating on the inorganic flat material that is the raw material. Therefore, it is expected that the UV shielding effect due to the dispersion efficiency will be improved.
さらに偏平状なので化粧品に仕上げて皮膚に塗布した場
合、皮膚表面を板状物質が覆うように広がるため、皮膚
を紫外線から守る効果が一層向上する。Furthermore, because of its flat shape, when it is applied to the skin as a cosmetic product, it spreads out to cover the skin surface, further improving the effect of protecting the skin from ultraviolet rays.

に用いた場合、比較的粉自体の流動性もよく、疎水化処
理を行う際凝集しにくいので、微粒子酸化チタン等を乾
式で疎水化処理するのに比べ非常に容易である。The ultraviolet ray-preventing flat pigment of the present invention whose surface has been hydrophobized has an improved feel on the skin and exhibits excellent dispersion in liquid paraffin, lanolin, stearic acid, fatty alcohol, etc. used in makeup cosmetics. . In particular, when mica is used as a material, the powder itself has relatively good fluidity and is less likely to aggregate during hydrophobizing treatment, making it much easier to hydrophobize microparticles such as titanium oxide using a dry process.
本発明の紫外線遮へい偏平状顔料は、硫酸チタニル水溶
液中へ偏平状物質の水懸濁液を添加し、熱加水分解を行
うことにより得られる。The ultraviolet-shielding flat pigment of the present invention can be obtained by adding an aqueous suspension of a flat substance to an aqueous titanyl sulfate solution and subjecting the suspension to thermal hydrolysis.

原料に用い、加水分解を行うことによっても得られる。In addition, except for the amount of ri, it can be produced by the same method as ordinary mica titanium pigments, for example, by the conventional method using titanyl sulfate (USP 3087828) or by thermally hydrolyzing titanyl sulfate in several steps. Method for multilayer coating of titanium oxide (Japanese Patent Application Laid-Open No. 6O-11560)
etc. can be used. Of course, it can also be obtained by hydrolyzing titanium tetrachloride as a starting material.

人工の薄片状物質も利用できる。As a raw material, muscovite, which is used for ordinary mica titanium and has a low impurity content, transparency, and excellent surface smoothness, is used, but other natural mica such as biotite and sericite, and fluorine tetrasilicon are also used. Artificial mica such as mica or taeniolite can be used. In addition, artificial flaky substances such as glass flakes can also be used.
