Description

【0001】
【発明の属する技術分野】
本発明は、特定の粒子形状及び平均粒子径をもつ酸化チタンと特定の鉄含有酸化チタン被覆セリサイトとを含有する化粧料に関し、更に詳しくは、肌上での伸び広がりが良く、紫外線遮断能を有し、分散性に優れ、自然な仕上がり、つまり青白さがなく、高い透明感が得られる化粧料に関する。
【0002】
【従来の技術】
従来化粧料に紫外線遮断効果を付与するには、有機の紫外線吸収剤を配合したり、酸化チタン・酸化亜鉛・酸化セリウム・酸化ジルコニウム等の無機化合物を微粒子化した粉体を配合する等の技術があった。
【0003】
【発明が解決しようとする課題】
有機の紫外線吸収剤を配合すると、紫外線遮断効果は著しく向上するが、多量に配合することにより、ベタツキや、皮膚への刺激等を生じるため、好ましくない。また、粒状の微粒子酸化チタンはUV−B領域(290〜320nm)に於いて高い紫外線遮断能を有するが、多量に配合すると、形状により分散性が不安定のため、微粒子酸化チタン特有の青白さが出て組成物及び化粧塗膜等も青白く不自然な仕上がりになっていた。これらの欠点を解消するために、紡錘状又は針状の微粒子酸化チタンが用いられてきた。しかし、多量に配合すると微粒子酸化チタン特有の仕上りの不自然さが出るため、配合量には限界があった。そこで、紫外線遮断能を更に向上させるために、高い透明感と伸び広がりの良さを持つ酸化チタン被覆体質顔料を併用する方法があったが、多量に配合すると化粧膜が白くなる等の欠点を有していた。そこで紫外線遮蔽効果を有し、安全で安定であり、伸び広がりが良く、仕上りのきれいな紫外線防御化粧料の開発が望まれていた。
【0004】
【課題を解決するための手段】
かかる事情に鑑み、本発明者らは、鋭意研究を行った結果、特定の粒子形状、粒子径を持つ微粒子酸化チタンと鉄含有酸化チタン被覆セリサイトとを含有することにより、優れた紫外線遮断効果を有し、安全で安定であり、伸び広がりが良く、透明感の高い仕上がりが得られることを見い出し本発明を完成するに至った。すなわち本発明は、粒子形状が紡錘状又は針状で短径が0.005〜0.1μm、長径が0.01〜0.5μmである微粒子酸化チタン1〜30重量%と、セリサイトの表面に酸化チタンを被覆し、且つ鉄を含有する鉄含有酸化チタン被覆セリサイト1〜50重量%とを含有する化粧料を提供するものである。

【0009】
前記酸化チタンをセリサイトに被覆する方法としては、セリサイトを酸化チタンで被覆できればいずれの方法を用いてもかまわないが、例えば、セリサイトを周囲温度において硫酸チタニルの希薄な強酸性溶液に懸濁させ、急速に約90〜100℃に加熱し、この温度に約2〜3時間維持して硫酸チタン溶液を加水分解することにより含水酸化物層がセリサイト上に析出されることによる方法や、セリサイトを熱湯中に懸濁させ、急速に強酸性濃硫酸チタニル溶液を加え、加水分解が完結するまで加熱沸騰を続けることにより加水分解と含水酸化チタンのセリサイト上ヘの析出を起こさせる方法等が挙げられる。
【0010】
更に、前記の酸化チタン被覆セリサイトを鉄処理する方法は、乾式方法、湿式方法等特に限定するものではないが、例えば、被覆顔料のスラリーを水溶性鉄塩(塩化第一鉄、塩化第二鉄、硫酸第一鉄、硫酸第二鉄、硝酸第一鉄、硝酸第二鉄等)の水溶液中に均一に分散せしめた後、撹拌下酢酸ナトリウムの水溶液を徐々に加えpHを3〜5とし、60℃以上の温度に加熱して鉄塩を加水分解することによって、非晶質の含水酸化物を前記被覆顔料の粒子表面に選択的に沈澱吸着(析出)せしめ、外観色が変化した段階でアルカリの水溶液を添加して加熱しながら系のpHを8〜9.5に調製し、その後、濾過、水洗、乾燥又は焼成して粉砕する方法等により鉄含有酸化チタン被覆セリサイトを得ることができる。
【0011】
また、前記鉄含有酸化チタン被覆セリサイトに処理する鉄の量は、特に限定するものではないが、Fe換算で酸化チタンに対して1〜15重量%の割合が好ましい。
【0012】
本発明に用いられる鉄含有酸化チタン被覆セリサイトの配合量は、化粧料中1〜50%であり、好ましくは1〜30%である。この範囲であれば、効果の発現や仕上がりの点において特に良好なものが得られる。
【0013】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cosmetic containing titanium oxide having a specific particle shape and an average particle diameter, and a specific iron-containing titanium oxide-coated sericite. The present invention relates to a cosmetic having excellent dispersibility, a natural finish, that is, no bluish whiteness and high transparency.
[0002]
[Prior art]
Conventionally, to impart an ultraviolet blocking effect to cosmetics, techniques such as compounding an organic ultraviolet absorber or compounding a powder made of fine particles of an inorganic compound such as titanium oxide, zinc oxide, cerium oxide, zirconium oxide, etc. was there.
[0003]
[Problems to be solved by the invention]
When an organic ultraviolet absorber is blended, the ultraviolet blocking effect is remarkably improved. However, if it is blended in a large amount, stickiness and skin irritation are caused, which is not preferable. In addition, although particulate titanium oxide has a high ultraviolet blocking ability in the UV-B region (290 to 320 nm), when it is blended in a large amount, the dispersibility is unstable depending on the shape, so that the bluish whiteness peculiar to the particulate titanium oxide is obtained. The composition and the decorative coating film were pale and unnatural. In order to solve these drawbacks, spindle-shaped or needle-shaped fine particle titanium oxide has been used. However, when blended in a large amount, an unnatural finish peculiar to the fine particle titanium oxide appears, so that the blending amount is limited. Therefore, in order to further improve the ultraviolet blocking ability, there has been a method in which a titanium oxide-coated pigment having high transparency and good spread is used in combination. Was. Therefore, there has been a demand for the development of a UV protective cosmetic which has an ultraviolet shielding effect, is safe and stable, has good elongation and spread, and has a beautiful finish.
[0004]
[Means for Solving the Problems]
In view of such circumstances, the present inventors have conducted intensive studies and as a result, by including fine particle titanium oxide having a specific particle shape and particle diameter and iron-containing titanium oxide-coated sericite , an excellent ultraviolet ray blocking effect. The present invention has been found to provide a safe, stable, well-expanded, and highly transparent finish. That is, the present invention is, particle shape fusiform or acicular in minor axis 0.005~0.1Myuemu, and 1 to 30 wt% fine particles of titanium dioxide is a major diameter 0.01 to 0.5 [mu] m, the surface of the sericite The present invention provides a cosmetic comprising 1 to 50% by weight of iron-containing titanium oxide-coated sericite , which is coated with titanium oxide.

If the long diameter or the short diameter of the fine particle titanium oxide is too small, the powder is agglomerated to deteriorate the ultraviolet protection effect and usability. If it is too large, the transparency is impaired, and the ultraviolet protection effect is also deteriorated, which is not good.
[0006]
The amount of the fine particles of titanium oxide used in the present invention, 1 to 30% by weight in the cosmetic (hereinafter simply indicated by "%".), Good Mashiku is 1-20%.

[0009]
As a method of coating the titanium oxide on the sericite , any method may be used as long as the sericite can be coated with the titanium oxide.For example, the sericite may be suspended in a dilute strong acid solution of titanyl sulfate at ambient temperature. Turbidity, rapidly heating to about 90 to 100 ° C., maintaining the temperature for about 2 to 3 hours, and hydrolyzing the titanium sulfate solution to deposit a hydrated oxide layer on sericite. Suspending sericite in boiling water, rapidly adding a strongly acidic concentrated titanyl sulfate solution, and continuing heating and boiling until the hydrolysis is completed, causes hydrolysis and precipitation of hydrous titanium oxide on the sericite . Method and the like.
[0010]
Further, the method of treating the titanium oxide-coated sericite with iron is not particularly limited, such as a dry method or a wet method. For example, a slurry of the coated pigment is treated with a water-soluble iron salt (ferrous chloride, ferric chloride). Iron, ferrous sulfate, ferric sulfate, ferrous nitrate, ferric nitrate, etc.) and uniformly dispersed in the aqueous solution, and then gradually added an aqueous solution of sodium acetate with stirring to adjust the pH to 3-5. A stage in which the appearance color is changed by selectively precipitating and adsorbing (precipitating) the amorphous hydrated oxide on the particle surface of the coated pigment by heating to a temperature of 60 ° C. or higher to hydrolyze the iron salt. The pH of the system is adjusted to 8 to 9.5 while adding an aqueous alkali solution and heating, and then obtaining iron-containing titanium oxide-coated sericite by a method such as filtration, washing with water, drying or calcination and grinding. Can be.
[0011]
The amount of iron to be treated on the iron-containing titanium oxide-coated sericite is not particularly limited, but is preferably 1 to 15% by weight based on Fe oxide in terms of Fe.
[0012]
The amount of iron-containing titanium oxide-coated sericite used in the present invention, 1 to 50% in the cosmetic, good Mashiku is 1 to 30%. Within this range, a particularly good one can be obtained in terms of the manifestation of the effect and the finish.
[0013]
