WIPO Patent Application WO/2008/044550
Kind Code:
A1
Abstract:
Disclosed is an O/W/O-type emulsion composition having at least one lignan compound disolved in the inner oil phase. Also disclosed is a process for producing the O/W/O-type emulsion composition, which comprises the steps of: 1) dissolving at least one lignan compound in an oil-and-fat to prepare a solution having the lignan compound dissolved therein; 2) emulsifying the solution in an aqueous phase to form an O/W-type emulsion; and 3) further emulsifying the O/W-type emulsion in an oil phase to form an O/W/O-type emulsion. The composition containing a lignan compound enables to increase the in vivo absorptivity of the lignan compound.
