ABSTRACT:
Undesired hydrophilic materials are readily removed from long chain hydrophobic alcohols, from long chain hydrophobic alcohol/glycoside surfactant mixtures and from solutions of glycoside surfactants in water immiscible solvents resulting from dissolving the glycoside surfactants in said solvents or mixing aqueous mixtures of glycoside surfactants with said solvents, by contacting the hydrophilic material containing hydrophobic composition with water in an amount, and for a time period sufficient, to extract at least a portion of the hydrophilic material from the hydrophobic composition and to form a separate aqueous phase and by separating the resulting aqueous phase from the hydrophobic composition. The process is particularly useful when employed in the context of a glycoside surfactant manufacturing process to remove polysaccharide by-products from a crude unreacted hydrophobic alcohol/glycoside surfactant reaction product mixture at a stage prior to the separation of the hydrophobic alcohol from the glycoside surfactant.
