摘要：
Processes for improving the taste of oral care raw materials using solvent extraction, said process comprising the steps of: providing a solid oral care raw material composition in need of treatment wherein said oral care raw material composition comprises an orally acceptable raw material and one or more undesirable non-polar materials contacting said oral care raw material composition with an extraction solvent to form an extraction mixture comprising a solid phase and a solvent phase and separating the solid phase from the extraction mixture 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.
