PROCESS FOR SURFACTANT TASTE AND/OR ODOR IMPROVEMENT |
摘要 |
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 (δD) ranging from about 15 to about 17 (MPa)0.5, a polar component (δP) ranging from 0 to about 9 (MPa)0.5 and a hydrogen bonding component (δH) 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. |
