Summary:Provided is a bicell structure composition capable of being prepared safely and easily without using an organic solvent, having an excellent feeling (sense of penetration, moisturization and tension) when used as an external agent for skin as well as superior storage stability. The bicell structure-containing composition is characterized by containing the following components (a)-(e): (a) a phospholipid; (b) 0.02-1 mass % of cholesterol and/or phytosterol; (c) at least one surfactant selected from polyoxyethylene cholesteryl ether and/or polyoxyethylene phytosteryl ether, in which the mean number of added moles of an ethylene oxide is 10-20; (d) at least one dihydric alcohol selected from propylene glycol, dipropylene glycol, and 1,3-butylene glycol; and (e) water, wherein the content mass ratio (a) / (c) of the component (a) and the component (c) is 0.4-2.0, and the content mass ratio { (a) + (c) } / (b) of the sum of the component (a) and the component (c) with respect to the component (b) is 5.0 or more.
