【発明の詳細な説明】
〈産業上の利用分野〉
この発明は、メーキャップ化粧料に配合されることによ

も高い紫外線吸収能を有する化粧料用酸化亜鉛に関する
。[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a cosmetic product that can be incorporated into makeup cosmetics to improve transparency and makeup durability, and also has high ultraviolet absorption ability. Regarding zinc oxide.
〈従来の技術〉
ファウンデーション、アイシャドー、頬紅、口紅などの
化粧ｔ４は、目もと、頬、口もとなどにみずみずしさを
与え、容姿を美しく、魅力的なものにするためのもので
あり、美が求められる女性の必需品である。<Conventional technology> Makeup T4, such as foundation, eye shadow, blusher, and lipstick, is used to add freshness to the eyes, cheeks, and mouth, to make one's appearance beautiful and attractive. It is a must-have item for women.
かかる化粧料は、通常、粉末、油、水、フックスなどか
らなり、このうち粉末は、着色顔料と、タルク、カオリ
ン、マイカ、二酸化チタン、硫酸バリウムなどの体質顔
料とからなる。Such cosmetics usually consist of powder, oil, water, fuchs, etc., of which the powder consists of coloring pigments and extender pigments such as talc, kaolin, mica, titanium dioxide, barium sulfate, etc.
また、化粧料には、紫外線から女性の肌を保護するため
紫外線吸収剤が配合されたものもある。Additionally, some cosmetics contain UV absorbers to protect women's skin from UV rays.
〈発明が解決しようとする課題〉
しかし、従来の化粧料においては、長時間塗膜の美しさ
を維持するのは困難であった。また、紫外線吸収能も未
だ充分なものとは言い難かった。<Problems to be Solved by the Invention> However, with conventional cosmetics, it has been difficult to maintain the beauty of the coating film for a long time. Furthermore, the ultraviolet absorbing ability was still far from sufficient.
この発明は、以上の事情に鑑みなされたものであって、
その目的とするところは、化粧料に配合されることによ
り、透明感がよく、化粧もちを改善することができ、し
かも紫外線から肌を有効に保護しうる化粧料用酸化亜鉛
を提供するにある。This invention was made in view of the above circumstances, and
The purpose is to provide zinc oxide for cosmetics that, when incorporated into cosmetics, provides good transparency, improves makeup retention, and can effectively protect the skin from ultraviolet rays. .
〈課題を解決するための手段および作用〉上記問題を解
決するためのこの発明の化粧料用酸化亜鉛は、乾式法で
製造されるものであって、比表面積２０〜３０ ｍ’
／ ｇ 、紫外線吸収率９０％以上を有するものである
。<Means and effects for solving the problems> The zinc oxide for cosmetics of the present invention for solving the above problems is produced by a dry method, and has a specific surface area of 20 to 30 m'
/g, and has an ultraviolet absorption rate of 90% or more.
ここで、比表面積の値はＢＥＴ吸着法に基づく値である
。また、紫外線吸収率の値は、吸収波長が３７０ｎｍの
場合の値である。Here, the value of the specific surface area is a value based on the BET adsorption method. Moreover, the value of ultraviolet absorption rate is the value when the absorption wavelength is 370 nm.
酸化亜鉛の製造方法としては、一般に乾式法（フランス
法）と湿式法とがある。There are generally two methods for producing zinc oxide: a dry method (French method) and a wet method.
湿式法は、塩化亜鉛溶液にソーダ灰を加えて液中に塩基
性炭酸亜鉛を沈澱させ、水洗、乾燥後、仮焼する方法で
ある。この方法によると、比表面積が７０ ｍ’ ／
ｇ程度のものしか得られず、また、炭酸イオンが不純物
として残留し、さらに紫外線吸収能が充分でないという
欠点がある。The wet method is a method in which basic zinc carbonate is precipitated by adding soda ash to a zinc chloride solution, followed by washing with water, drying, and calcining. According to this method, the specific surface area is 70 m'/
However, there are disadvantages in that only about 1.5 g of carbonate ions can be obtained, carbonate ions remain as impurities, and ultraviolet absorption ability is not sufficient.
これに対して、この発明における乾式法は、溶融させた
金属亜鉛をレトルトの中で１０００℃程度に加熱し、発
生する亜鉛蒸気を空気を用いて酸化し、生成した酸化亜
鉛を送風機で空冷管に送って冷却し、コレクター及びバ
グフィルタ−で分離、捕集する方法である。On the other hand, in the dry method of this invention, molten metal zinc is heated to about 1000°C in a retort, the generated zinc vapor is oxidized using air, and the generated zinc oxide is transferred to an air-cooled tube using a blower. In this method, the waste is sent to a refrigerator, cooled, and separated and collected using a collector and bag filter.
この乾式法によれば、不純物の混じらない高純度の酸化
亜鉛を得ることができる。さらに、乾式法で得られた酸
化亜鉛は、湿式法で得られたものに比べて、紫外線吸収
能が高く、分散性に秀れ、化粧料の光沢をより向上させ
る。According to this dry method, highly pure zinc oxide without any impurities can be obtained. Furthermore, zinc oxide obtained by the dry method has higher ultraviolet absorption ability and excellent dispersibility than that obtained by the wet method, and improves the gloss of cosmetics.
かかる乾式法により比表面積か２０〜３０ｍ２７ｇおよ
び紫外線吸収率９０％以上の酸化亜鉛を得るには、金属
亜鉛蒸気を一定流速、例えば０．５〜１．５ｋｉ／時で
流し、これに一定量例えば１．８Ｎｍ’／分程度の割合
で空気を吹き付ければよい。In order to obtain zinc oxide having a specific surface area of 20 to 30 m27g and an ultraviolet absorption rate of 90% or more by such a dry method, metallic zinc vapor is flowed at a constant flow rate, for example, 0.5 to 1.5 ki/hour, and a certain amount of, for example, Air may be blown at a rate of about 1.8 Nm'/min.
ここで、比表面積を２０〜３０ ｍ２／ ｇの範囲に特
定したのは、比表面積が２０ ｍ’ ／ ｇ未満の酸化
亜鉛では、これを化粧料に配合した場合、化粧しちが悪
くなり、さらに可視光線透過率や紫外線吸収率も低下す
るためであり、また比表面積が３０ｍ’／ｇを越えるも
のは現在の乾式法では工業的に製造することができない
からである。Here, the reason why the specific surface area is specified to be in the range of 20 to 30 m2/g is because zinc oxide with a specific surface area of less than 20 m'/g will have poor makeup application when added to cosmetics. Furthermore, the visible light transmittance and ultraviolet absorption rate are also lowered, and the specific surface area exceeding 30 m'/g cannot be industrially produced using the current dry method.
また、紫外線吸収率を９０％以上としたのは、紫外線吸
収率が９０％未満の酸化亜鉛では、これを化粧料に配合
した場合、十分な紫外線吸収能を示さなくなるためであ
る。Further, the reason why the ultraviolet absorption rate is set to 90% or more is because zinc oxide with an ultraviolet absorption rate of less than 90% does not exhibit sufficient ultraviolet absorption ability when added to cosmetics.
この発明の化粧料用酸化亜鉛は顔料として、従来既知の
他の配合成分と共に、ファウンデーション、アイシャド
ー、頬紅、口紅等の化粧料に配合される。The zinc oxide for cosmetics of the present invention is blended as a pigment into cosmetics such as foundations, eye shadows, blushers, lipsticks, etc., along with other conventionally known ingredients.
他の配合成分としては、タルク、マイカ、カオリン、二
酸化チタン、青色顔料などの粉末、油分、アルコール、
８ｆ４が例示される。Other ingredients include talc, mica, kaolin, titanium dioxide, blue pigment powder, oil, alcohol,
8f4 is exemplified.
この場合、酸化亜鉛の微粒子は、粒子そのまま又は油分
と混合してローラなどにより混練りしてペースト状にし
て化粧料に配合することができる。In this case, the fine particles of zinc oxide can be blended into the cosmetic as they are or mixed with oil and kneaded with a roller or the like to form a paste.
この発明の酸化亜鉛の化粧料への配合量は、１〜５０重
量％の割合であるのが好ましい。これは、１重量％未満
の場合、添加効果が殆どみられないからであり、５０重
量％を越えた場合、化粧料の透明感が損なわれるからで
ある。The amount of zinc oxide of this invention incorporated into the cosmetic is preferably 1 to 50% by weight. This is because when the amount is less than 1% by weight, there is almost no effect of addition, and when it exceeds 50% by weight, the transparency of the cosmetic is impaired.
なお、比表面積２０ ｍ’ ／ ｇの酸化亜鉛の場合、
その粒径は、０゜１μ−程度である。In addition, in the case of zinc oxide with a specific surface area of 20 m'/g,
Its particle size is approximately 0°1μ.
