本発明の油中水型乳化化粧料に用いられる(A)有機変性粘土鉱物は、三層構造を有するコロイド性含水ケイ酸アルミニウムの一種で、一般に下記一般式(1)で表される粘土鉱物を第四級アンモニウム塩型カチオン界面活性剤で変性したものである。
(X,Y)2―3(Si,Al)4O10(OH)2Z1/3・nH2O (1)
(但し、X=Al,Fe(III),Mn(III),Cr(III)、Y=Mg,Fe(II),Ni,Zn,Li、Z=K,Na,Ca)
本発明の油中水型乳化化粧料に用いられる(B)疎水性シリカは、無水ケイ酸であるシリカ表面のシラノール基(水酸基)が、ジメチルジクロロシラン処理、オクチルシラン処理、ヘキサメチルジシラザン処理、ジメチルシリコーンオイル処理又はメタクリロキシシラン処理されたものである。なかでも、化粧料の安定性向上効果に優れることから、ジメチルジクロロシラン処理、オクチルシラン処理、ヘキサメチルジシラザン処理又はジメチルシリコーンオイル処理されたものが好ましい。
本発明において用いられる(C)シリコーン系界面活性剤は、オルガノポリシロキサンを主骨格として側鎖にポリオキシアルキレン基と炭素数2以上のアルキル基を有するものであり、例えば、ポリ(オキシエチレン・オキシプロピレン)メチルポリシロキサン共重合体やアルキル鎖・シリコーン鎖分岐型ポリオキシエチレンメチルポリシロキサン共重合体等を使用することができる。
本発明の油中水型乳化化粧料に用いられる(D)油分は、総油分の10~50質量%を非極性炭化水素油が占める。総油分に占める非極性炭化水素油の割合が当該範囲外であると、安定性が損なわれ、分離を引き起こす場合がある。
本発明の油中水型乳化化粧料に用いられる(E)水相成分は、水(イオン交換水、精製水、自然水等)あるいは水性溶媒の他、通常化粧料に使用可能なものを、化粧料の安定性を損なわない範囲で配合することができる。
