Being the method of improving the taste of the water soluble surface active agent making use of liquid-liquid solvent extraction, aforementioned method, being the process which offers the water soluble surface active agent constituent which needs processing, the aforementioned water soluble surface active agent constituent, contains the water soluble surface active agent and the non-polarized material whose one or more is not desirable, making process and the aforementioned water soluble surface active agent constituent contact with the extractant and the water, the process which forms the extraction blend which includes water phase and solvent phase and the process which separates water phase from solvent phase and, to include, the extractant approximately 15 - approximately 17 (MPa) 0.5The dispersion force component of the range (D), 0 - approximately 9 (MPa) the polarity component of 0.5 ranges (P), 0 - approximately 11 (MPa) the hydrogen bond component of 0.5 ranges (H), it is selected from the solvent which possesses individual hansen solubility parameter. The buccal cavity CARE constituent which is formed contains the processing water soluble surface active agent constituent and that kind of processing being completed water soluble surface active agent constituent by that kind of method.液液溶媒抽出を用いて水溶性界面活性剤の味を改善する方法であって、前記方法が、処理を必要とする水溶性界面活性剤組成物を提供する工程であって、前記水溶性界面活性剤組成物が、水溶性界面活性剤と、1つ以上の望ましくない非極性材料とを含有する、工程と、前記水溶性界面活性剤組成物を抽出溶媒及び水と接触させて、水相及び溶媒相を含む抽出混合物を形成する工程と、水相を溶媒相から分離する工程と、を含み、抽出溶媒は、約15~約17(MPa)0.5の範囲の分散力成分(δD)、0~約9(MPa)0.5の範囲の極性成分(δP)、0~約11(MPa)0.5の範囲の水素結合成分(δH)の、個々のハンセン溶解度パラメーターを有する溶媒から選択される。そのような方法により生成された処理済み水溶性界面活性剤組成物と、そのような処理済み水溶性界面活性剤組成物を含有する口腔ケア組成物。
