The present patent application relates to a silicone-free composition in the form of a water-in-oil emulsion, comprising, in particular in a physiologically acceptable medium: a) a continuous oily phase containing: i) at least one nonvolatile vegetable oil; and ii) at least one volatile alkane; and b) an aqueous phase dispersed in said oily phase containing: c) at least one polyglyceryl polyricinoleate surfactant; and d) at least one C3 or C4 alkanediol; and e) at least glycerol. The invention also relates to a method for coating keratin materials, more particularly for making up and/or caring for keratin materials, such as the skin, characterized in that it comprises the application, to the keratin materials, of a composition as defined above.
