摘要：
D0.5P0.5H0.5.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 (d) ranging from about 15 to about 17 (MPa) a polar component (d) ranging from 0 to about 9 (MPa) and a hydrogen bonding component (d) ranging from 0 to about 11 (MPa) Treated water soluble surfactant compositions produced by such processes and oral care compositions containing such treated water soluble surfactant compositions.
