(a)両末端反応性ジオルガノポリシロキサン(粘度30mPa・s)500gを容量2リットルのポリエチレンビーカーに仕込み、ラウロイルメチルタウリンナトリウム22.5gおよびイオン交換水50gをホモミキサーで5000rpmで攪拌しながら徐々に滴下して転相させた。増粘させた後、攪拌速度を7000rpmに上げて15分間攪拌し、イオン交換水を450g加えて希釈した。次いで、卓上加圧ホモジナイザー(APVゴーリン製)で70MPaにて1回乳化分散して、(a)の水エマルジョン(1)を得た。この水エマルジョン(1)を105℃で3時間乾燥して水を揮発除去した固形分について、GPCによるPS換算の分子量を求めたところ6000であった。固形分は51.0%であった。
容量2リットルのポリエチレンビーカーにオクタメチルシクロテトラシロキサン450gとイオン交換水500g、ラウロイルメチルタウリンナトリウム6.75gを仕込み、ホモミキサー撹拌2000rpmにより予備混合した後、クエン酸4gを添加して、70℃に昇温してホモミキサー5000rpmにより24時間乳化重合した。卓上加圧ホモジナイザー(APVゴーリン製)で50MPaにて1回乳化分散することにより高分子量の(a)の水エマルジョンを得た。次いで10%炭酸ナトリウムを加えてpH7に調整して(a)の水エマルジョン(2)を得た。この水エマルジョン(2)を105℃で3時間乾燥して水を揮発除去した固形分について、GPCによるPS換算の分子量を求めたところ10000であった。固形分は46.5%であった。
スチロール角型ケース(タテ36×ヨコ36×高さ14mm)に、シリコーン微架橋物を面より僅かに出るように仕込み、表面を平たんにして試験面とする。デュロメーターの加圧板を試験面上20mm位置に置き、試験面表面と加圧板が平行になるように維持された状態で、加圧板を試験片に押し当てて針の目盛りを読み取る。この操作を5回行い平均値を測定値とした。なお、測定により針が動かなかった場合はNA(Not Applicable)とした。
下記に示す条件によりG’(貯蔵弾性率)およびG”(損失弾性率)を求め複素弾性率とtanδを求めた。

表1の結果から明らかなように、本発明の実施品である実施例1~24のパウダーファンデーションは、プレス成型性、耐衝撃性、転がり性、しっとり感、テカリ抑制効果の全ての項目に優れたパウダーファンデーションであった。
一方、成分(A)の代わりに、2%のジメチルポリシロキサンで被覆したタルクを用いた比較例1では、プレス成型性及び耐衝撃性に劣り、満足のいくしっとり感を得られなった。油剤量を10%より多くした比較例2では、満足のいく転がり性が得られず、化粧料の油剤量が多く、余分な皮脂を取り込む粉体量が減ったために、満足のいく経時でのテカリ抑制効果を得ることが出来なかった。また、成分(B)の球状粉体の含有量を変えた比較例3及び4に関しては、球状粉体の含有量が15%未満であると、満足のいく転がり性と経時でのテカリ抑制効果を得ることが出来ず、球状粉体の含有量が40%を超えると、プレス成型性及び耐衝撃性に劣り、満足のいくしっとり感も得ることが出来なかった。
