    • Processes for improving the taste of water-soluble surfactants using liquid-liquid solvent extraction, said process comprising the steps of: providing a water-soluble surfactant composition in need of treatment wherein said water-soluble surfactant composition comprises a water-soluble surfactant and one or more undesirable non-polar materials; contacting said water-soluble surfactant composition with an extraction solvent and water to form an extraction mixture comprising an aqueous phase and a solvent phase; and separating the aqueous phase from the solvent phase; wherein the extraction solvent is selected from solvents having individual Hansen solubility parameters of a dispersion force component (δ D ) ranging from about 15 to about 17 (MPa) 0.5 , a polar component (δ P ) ranging from 0 to about 9 (MPa) 0.5 and a hydrogen bonding component (δ H ) ranging from 0 to about 11 (MPa) 0.5. Treated water-soluble surfactant compositions produced by such processes and oral care compositions containing such treated water-soluble surfactant compositions.
    • 使用液 - 液溶剂萃取来改善水溶性表面活性剂的味道的方法,所述方法包括以下步骤:提供需要处理的水溶性表面活性剂组合物,其中所述水溶性表面活性剂组合物包含水溶性表面活性剂和一种 或更不希望的非极性材料; 使所述水溶性表面活性剂组合物与提取溶剂和水接触以形成包含水相和溶剂相的萃取混合物; 并将水相与溶剂相分离; 其中提取溶剂选自具有范围为约15至约17(MPa)0.5,极性组分(dP)为0至约9(MPa)0.5的分散力组分(dD)的单独Hansen溶解度参数的溶剂和0至约9(MPa) 0〜11(MPa)0.5以下的氢键成分(dH)。 通过这些方法制备的经处理的水溶性表面活性剂组合物和含有这种经处理的水溶性表面活性剂组合物的口腔护理组合物。
