<p>Disclosed is an inverted vesicle composition containing (A) a sphingosine represented by the general formula (1) below, (B) a fatty acid having 16-30 carbon atoms, (C) a hydrocarbon oil, (D) an ester oil which is in a liquid state at 25°C and (F) water. In this inverted vesicle composition, the mass ratio between the component (C) and the component (D) satisfies the following relation: 1 = (C)/(D) < 1000, and a surfactant having a molecular weight of not more than 1000 is contained in an amount of not more than 1% by mass.</p> |
