Description
ここに、f(v)=1−I104(c)/(I110(v)+I112(v)+I114(v)+I104(c))であって
、I104(c) はカルサイトの104 面におけるX線回折強度、I110(v) はバテライトの100面におけるX線回折強度、I112(v) はバテライトの112面におけるX線回折強度、I114(v) はバテライトの114面におけるX線回折強度である。
株式会社堀場製作所製レーザー回折/散乱式粒度分布測定装置LA−750を用いて、体積基準による体積メジアン径D50を測定した。
(株)堀場製作所製電気伝導度計ES−12を用いて測定した。
SEM写真から粒子100個をランダムに選び、長径と短径をそれぞれ測定して、短径/長径比を求めて、球状性とした。
容量500mLのビーカーにイオン交換水300mLを入れる。このイオン交換水を攪拌速度250rpmで攪拌しながら、これに試料である表面処理球状炭酸カルシウム粉体1gを投入した後、上記攪拌速度で更に1分間撹拌する。攪拌を止めた後、ビーカー内のイオン交換水の白濁度を目視で調べて、沈降又は白濁がないとき、「よい」、少しでも沈降又は白濁があれば「悪い」とする。そして、試験結果が「よい」とき、イソプロピルアルコール5mLとイオン交換水295mLの混合液中で再度、同様に試験する。以後、試験結果が「悪い」になるまで、イソプロピルアルコールを5mLずつ増やし、一方、混合液量が300mLになるようにイオン交換水を5mLずつ減らして試験する。最終的に試験結果が「悪い」になったときのイソプロピルアルコール量を撥水性の指標とした。このように、最終的に試験結果が「悪い」になったときのイソプロピルアルコール量が多いほど、試料である表面処理球状炭酸カルシウム粉体はすぐれた撥水性を有する。
スライドガラスに25mm幅の両面テープを貼り、その上に表面処理球状炭酸カルシウム粒子0.5g程度を載せて、これを化粧用パフで展ばした。次いで、このような両面テープ上に展ばした表面処理球状炭酸カルシウム粒子について、摩擦感テスターKES−SE(カトーテック社製)でシリコーンゴム製摩擦子を用いて摩擦係数を測定した。このようにして求めた摩擦係数(μ)の20mm間の平均値から平均摩擦係数と摩擦係数の平均偏差を算出して、滑り性を評価した。
実施例1
(球状炭酸カルシウムの製造)
1L容量のビーカーに塩化カルシウム2水和物9.8gを入れ、イオン交換水で溶解して水溶液200mLを調製した。別に、炭酸ナトリウム35gをイオン交換水で溶解して水溶液200mLを調製すると共に、ヘキサメタリン酸ナトリウム0.05gをイオン交換水に溶解して水溶液10mLを調製した。
攪拌機を備えた10L容量のステンレス製容器中の純水3Lに上記球状炭酸カルシウム粒子500gを分散させ、常温にて10分間攪拌して、球状炭酸カルシウムの水分散液を得た。
上記含水シリカ被覆球状炭酸カルシウム粉体50gをポリエチレン袋に入れ、更に、イソプロピルアルコール30mLをこれに加えて、手で揉みながら、更に、イソプロピルアルコールを少量ずつ加えて、混練物を得た。
実施例1において、含水シリカ被覆球状炭酸カルシウム粒子をシリコーン処理するに際して、シリコーンとして、ハイドロジェンジメチコンKF−9901の1.5gに代えて、信越化学工業(株)製トリエトキシシリルエチルポリジメチルシロキシエチルヘキシルジメチコンKF−9909を1.5gを用いた以外は、実施例1と同様にして、シリコーン処理を行った。
実施例1において、球状炭酸カルシウム粒子に含水シリカ被覆処理を施すことなく、実施例1と同様にして、シリコーン被覆処理を行って、比較例としての表面処理球状炭酸カルシウム粒子を得た。
実施例1において、ハイドロジェンジメチコンKF−9901の1.5gを用いるシリコーン被覆処理に代えて、シランカップリング剤として、デグサ社製ビス(3−〔トリエトキシシリル〕プロピル)テトラサルフォンSi69の1.5gを用いた以外は、実施例1と同様にして、比較例としての表面処理球状炭酸カルシウム粒子を得た。
撹拌機を備えた3L容量ビーカー中に実施例1で得た球状炭酸カルシウム粒子100gとイオン交換水1Lを入れ、攪拌速度200rpm、温度30℃で10分間攪拌して、球状炭酸カルシウム粒子をイオン交換水に分散させて、水分散液を調製した。別に、ミリスチン酸ナトリウム3.5gをイオン交換水1.2Lに溶解させて水溶液を調製した。
実施例3〜4及び比較例4〜6
表2に示す処方物をそれぞれ容量75mLのガラス容器に入れ、ラボミルサープラス(アズワン社製)を用いて1分間混合し、得られた混合粉末を金皿に入れ、40kg/cm2 の圧力で3分間加圧成形して、実施例及び比較例によるパウダーファンデーションを得た。
これら実施例及び比較例によるパウダーファンデーションについて、15人のパネリストによって感触、即ち、肌触りの良し悪しを評価した。評価基準は以下の通りとした。結果を表2に示す。
A:9〜12名のパネリストが感触良好と感じた。
B:5〜8名のパネリストが感触良好と感じた。
C:4名以下のパネリストが感触良好と感じた。
