Abstract
A method is provided for purifying crude inclusion complexes of cyclodextrin which is used as a host material, in combination with a guest material, such as light mineral oil. After the crude cyclodextrin complex is formed in an aqueous media, the moisture content of the crude cyclodextrin complex is substantially reduced before it is washed with a wash solvent to substantially eliminate uncomplexed guest molecules.
