PROBLEM TO BE SOLVED: To provide a preparation for external use obtained by stably blending liposome to the outer water phase of the W/O/W type emulsion and the preparation for external use for the skin or scalp to give an effect of the physiologically active components by further including an oily physiologically active component in the liposome and blending an aqueous physiologically active component to an inner aqueous phase.SOLUTION: This W/O/W type skin or scalp preparation for external use is provided by containing a lecithin as a constituting component of the liposome, using a nonionic surfactant as the surfactant of the W/O/W emulsion and further having &le2 pts.wt. content of the nonionic surfactant based on 1 pt.wt. lecithin.COPYRIGHT: (C)2007,JPO&INPIT【課題】W/O/W型エマルションの外水相にリポソームを安定に配合した外用剤を提供する。さらに、リポソームに油性の生理活性成分を内包し、内水相に水性の生理活性成分を配合することにより生理活性成分の効果させた皮膚又は頭皮用の外用剤を提供する。【解決手段】リポソームの構成成分としてレシチンを含有し、W/O/Wの界面活性剤として非イオン性界面活性剤を用い、さらにレシチン1重量部に対し非イオン性界面活性剤の含有量を2重量部以下にする。
