Abstract
【解決手段】 少なくとも表面に油性薬剤が保持された、水で膨潤した粒状ゲルであって、界面活性剤を実質的に含まない薬剤ゲルを、水中に加え、その水とゲルを攪拌することにより油性薬剤を空気中に拡散させる。
【選択図】なし
Description
(2)前記粒状ゲルが水で膨潤した吸水性ポリマーである請求項1記載の薬剤ゲル。
(4)上記(1)〜(3)のいずれかに記載の薬剤ゲルを水中に加え、その水とゲルを攪拌して油性薬剤を空気中に拡散させる、薬剤の拡散方法。
なおグリセリン等を用いる場合には、水で膨潤させたゲルに更に吸収させることができないことから、上記のとおり、水溶液として調製したものをゲル化剤に吸収させて膨潤させる必要がある。
これらの他の成分は、水系ゲル化剤の膨潤時に用いる水溶液中に含有させておくことにより容易に薬剤ゲルに含有、保持させることができ、必要に応じて適宜設定することができる。
この薬剤拡散装置1は、フィン4の回転によって、吸水管3の先端の吸水口5から入った水が遠心力によってテーパーのついた吸水管をのぼっていき、上方の噴出口6から噴出されてタンク2内に水幕を形成し、この水幕にタンク2内の空気を接触させることで、空気に油性薬剤の成分を含ませ、該空気を空気排出口9から排出させるものである。
吸水管3の内面には、その軸長方向に沿って1本又は複数本の導流条が隆起形成されており(図示せず)、この導流条は、吸水管内の水の攪拌部材として機能している。これで効率的に攪拌することで、吸水管内の水を遠心力によりテーパーを伝わせて上昇させることができる。
油性薬剤として芳香成分を用いて、球状の薬剤ゲル(芳香ビーズ)を製造した実施例を例示する。
吸水性ポリマーとしてアクリルアミド−アクリル酸塩共重合体(粒径約1.5〜2mm)を用いて、下記の処方の各成分を含有する芳香液を吸水させることにより、下記処方の通りの薬剤ゲルを得た。膨潤後の薬剤ゲルの粒径は約7mmであった。
図1に示す装置を二台用意し、そのタンク部に水を200mL注ぎ、ここに上記処方1又は処方2にて調製した芳香ビーズ8gをそれぞれ投入した。これらをそれぞれ容積約2000L(0.8×1.3×1.9m)のチャンバー内(無換気条件)に置き、同時に通電を開始し、タンク内の水を回転数約1350rpm及び風量約0.5L/秒の条件で攪拌した。
通電開始5分後チャンバー内の香りの強度をモニター試験(13人)にて評価した。
試験は2回繰り返して実施し、通電開始5分後で香りが強いと感じるチャンバーを選択した。試験結果は下記表2の通りである。
また、処方2により調製した薬剤ゲルを用いた場合には、小泡による膜が形成され、見た目が悪いのに対し、処方2により調製した薬剤ゲルを用いた場合には、このような小泡は見られず、外観上も美しく好ましかった。
