PROBLEM TO BE SOLVED: To provide a liposome composition encapsulating an oil component, in which transparency and liposome particle size uniformity are maintained as much as possible in the liposome-containing composition, and each liposome particle size is relatively large. SOLUTION: (A) hydrogenated phospholipid, and (B) polyoxyethylene hydrogenated castor oil having an average addition mole number of ethylene oxide of 40 to 95 are mass ratio (A)/(B)=2-8. And a liposome containing an oil component.
