There is provided a spray base material that can be safely used with a sense of security, that prevents leakage of liquid from a spray container, that is sprayable under any condition (when inverted, for example), that is sprayable to achieve uniform coating of the surface of an object (surface to be sprayed) without scattering, that causes no dripping from a sprayed surface, and that is safe when sprayed on a skin surface and the like; and a spray base material with an excellent sprayability that can include both hydrophilic and hydrophobic low-molecular compounds such as physiologically active compounds and perfume components to be used in pharmaceuticals, agrochemicals, and cosmetics, and that has a sustained release property. A spray base material comprising an aqueous medium that is gelled by a low-molecular gelator in the medium, wherein the low-molecular gelator includes one, two, or more compounds selected from a group consisting of low-molecular compounds capable of gelling the aqueous medium via self-assembly.
