Treated surfactant composition containing a water-soluble surfactant and exhibiting improved taste, said composition comprising: a water-soluble surfactant selected from alkyl phosphate surfactants, alkyl phosphate ethoxylated surfactants, betaine surfactants, betaine ethoxylated surfactants, amine oxide surfactants, and mixtures thereof and water; wherein the composition further comprises: less than about 4%, by weight of the water-soluble surfactant, of total undesirable non-polar materials; less than about 2.5%, by weight of the water-soluble surfactant, of alcohols having a carbon chain length of greater than 4; less than about 1%, by weight of the water-soluble surfactant, of amine and amide materials; and less than about 1%, by weight of the water-soluble surfactant, undesirable non-polar materials selected from aldehydes, esters, ketones, and organic acids. Such compositions wherein the compositions have been subjected to liquid-liquid extraction processes.

Water soluble surfactant composition having improved taste

Compositions useful in liquid-liquid extraction processes for improving the taste of water-soluble surfactants, said composition comprising: from about 5% to about 60%, by weight of the composition, of water soluble surfactant; from about 10% to about 90%, by weight of the composition, of water; from about 10% to about 90%, by weight of the composition, of extraction solvent; at least 0.01%, by weight of the composition, of undesirable non-polar materials; wherein the extraction solvent is selected from solvents having individual Hansen solubility parameters of a dispersion force component (&#x3b4;) ranging from about 15 to about 17 (MPa), a polar component (&#x3b4;) ranging from 0 to about 9 (MPa)and a hydrogen bonding component (&#x3b4;) ranging from 0 to about 11 (MPa).

Liquid-liquid extraction composition useful in processing water-soluble surfactants

Water-soluble surfactant compositions having improved taste

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 (&#x3b4;) ranging from about 15 to about 17 (MPa), a polar component (&#x3b4;) ranging from 0 to about 9 (MPa)and a hydrogen bonding component (&#x3b4;) 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.
