前記本発明における水性毛髪洗浄剤の、頭皮に適用した後に、泡立て、洗い流し、乾燥する使用。
上記乾燥は、自然乾燥、タオルドライ、ドライヤー使用いづれの方法を行ってもよい。洗髪、乾燥後の毛髪は、立ち上がり、ボリューム効果、ごわつきの抑制、残留感の抑制に優れている。
まず、以下の例で用いたポリマーの製造方法を説明する。
硫酸ジエチル6.5g(0.042モル)と2-エチル-2-オキサゾリン34.4g(0.36モル)を、脱水した酢酸エチル87.0gに溶解し、窒素雰囲気下8時間加熱還流し、数平均分子量1.3×103のポリ(N-プロピオニルエチレンイミン)を合成した。ここに、側鎖一級アミノプロピル変性ポリジメチルシロキサン(重量平均分子量5×104、アミン当量2000)100gを加えて、N-プロピオニルエチレンイミン-ジメチルシロキサン共重合体を淡黄色ゴム状半固体(138g、収率98%)として得た。最終生成物中のオルガノポリシロキサンセグメントの含有率は71質量%、重量平均分子量は7×104であった。溶媒としてメタノールを使用した塩酸による中和滴定の結果、最終生成物中に約20質量%のアミノ基が残存していることがわかった。また、主鎖を構成するオルガノポリシロキサンセグメント(a)と、ポリ(N-アシルアルキレンイミン)セグメント(b)との質量比(a/b)は、71/29であった。
硫酸ジエチル6.2g(0.040モル)と2-エチル-2-オキサゾリン27.2g(0.27モル)を、脱水した酢酸エチル67.7gに溶解し、窒素雰囲気下8時間加熱還流し、数平均分子量8×102のポリ(N-プロピオニルエチレンイミン)を合成した。ここに、側鎖一級アミノプロピル変性ポリジメチルシロキサン(重量平均分子量5×104、アミン当量2000)100gを加えて、N-プロピオニルエチレンイミン-ジメチルシロキサン共重合体を淡黄色ゴム状半固体(131g、収率98%)として得た。最終生成物中のオルガノポリシロキサンセグメントの含有率は75質量%、重量平均分子量は6.7×104であった。溶媒としてメタノールを使用した塩酸による中和滴定の結果、最終生成物中に約20質量%のアミノ基が残存していることがわかった。また、主鎖を構成するオルガノポリシロキサンセグメント(a)と、ポリ(N-アシルアルキレンイミン)セグメント(b)との質量比(a/b)は、75/25であった。
硫酸ジエチル5.5g(0.036モル)と2-エチル-2-オキサゾリン144.5g(1.46モル)を、脱水した酢酸エチル304.6gに溶解し、窒素雰囲気下8時間加熱還流し、数平均分子量4.3×103のポリ(N-プロピオニルエチレンイミン)を合成した。ここに、側鎖一級アミノプロピル変性ポリジメチルシロキサン(重量平均分子量5×104、アミン当量2000)100gを加えて、N-プロピオニルエチレンイミン-ジメチルシロキサン共重合体を淡黄色固体(245g、収率98%)として得た。最終生成物中のオルガノポリシロキサンセグメントの含有率は40質量%、重量平均分子量は1.25×105であった。溶媒としてメタノールを使用した塩酸による中和滴定の結果、最終生成物中に約29質量%のアミノ基が残存していることがわかった。また、主鎖を構成するオルガノポリシロキサンセグメント(a)と、ポリ(N-アシルアルキレンイミン)セグメント(b)との質量比(a/b)は、50/50であった。
硫酸ジエチル0.8g(0.005モル)と2-エチル-2-オキサゾリン12.8g(0.14モル)を脱水した酢酸エチル29.0gに溶解し、窒素雰囲気下8時間加熱還流し、数平均分子量2.7×103のポリ(N-プロピオニルエチレンイミン)を得た。さらに、側鎖一級アミノプロピル変性ポリジメチルシロキサン(重量平均分子量1×105、アミン当量20000)100gを加えて、N-プロピオニルエチレンイミン-ジメチルシロキサン共重合体を淡黄色ゴム状固体(111g、収率98%)として得た。最終生成物中のオルガノポリシロキサンセグメントの含有率は88質量%であり、重量平均分子量は1.1×105であった。溶媒としてメタノールを使用した塩酸による中和滴定の結果、最終生成物中にアミノ基は残存していないことがわかった。また、主鎖を構成するオルガノポリシロキサンセグメント(a)と、ポリ(N-アシルアルキレンイミン)セグメント(b)との質量比(a/b)は、88/12であった。
表2に示す水性毛髪洗浄剤(シャンプー)を、常法により調製し、以下の評価方法により評価した。その結果を表2に示す。なお、pHは各組成物を水で20質量倍希釈し、25℃で測定した値である。
図1は、本実施例における毛髪の立ち上がり易さの評価方法を説明する図である。
7×7cmの面積に(シートに対し)同じ方向に60°の角度で200本/cm2の密度を植毛したトレス(髪の長さ30cm)を用いた。本トレスを各試験サンプル(2g)で洗浄・すすぎ後、50℃(乾燥機)で下向き(髪が垂れ下がる様に)に乾燥した後に、髪の生え面を上向きに戻して髪全体を生え向きと逆の方向に流した時のシートから髪の最頂部(最表面)までの高さ(図1中、矢印間の高さ)を測定した。
コーカシアン毛(ブロンド)を植毛したウィッグ(マネキンの頭で髪の長さはショート~ミディアム)を用い、各試験サンプル(6g)で洗浄・すすぎ後、タオルドライしてドライヤー(手グシのみ)で完全に乾燥した後の見た目のボリューム感を5段階評価で判定した。判定は、以下の処方にて得られた標準シャンプーのボリューム感を標準(評価3点)として採点した。評価5点は非常にボリュームがある;評価4点はボリュームがある;評価2点はあまりボリュームがない;評価1点はボリュームがないと判定し、表示したスコアは6名の評価の積算値で求めた(30点満点)。
