<P>PROBLEM TO BE SOLVED: To efficiently prepare a powdery sphingoglycolipid-containing composition free from defects such as stickiness or lump formation. <P>SOLUTION: The powdery sphingoglycolipid-containing composition is prepared by bringing a sphingoglycolipid-containing substance into contact with a cyclic oligosaccharide, such as β-cyclodextrin and/or γ-cyclodextrin, in the presence of a solvent having below-described properties (a) and (b) and water in a volume ratio of the solvent to water of (1/50)-3 and then drying the substance. The solvent used is other than water and has such properties that (a) the solvent and water are mutually soluble in each other and (b) the solvent is included by the cyclic oligosaccharide in the presence of water or in an anhydrous state. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
