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.本發明可提供一種噴霧用基劑，其為可預防自噴霧容器漏出其液體，且可以在任何環境下(例如倒置狀態下)亦可以噴霧，噴霧時不會飛散，可以充分地被覆目的物(噴霧面)之表面，且不會自噴霧面滴下液體，更為由即使噴霧於皮膚表面亦極安全之化合物所構成之可安心，安全地使用之噴霧用基劑者。除此外，並可提供不僅可以極順利地噴霧，對醫農藥或香料化粧品所用生理活性化合物或芳香成份等低分子化合物，不論其為親水性或疏水性，可以共存其雙方予以包合，還可以具備緩釋放性之噴霧用基劑者。其解決手段：包含藉由媒體中之低分子凝膠化劑所凝膠化之水性媒體，該低分子凝膠化劑係具有藉由自我集合化可凝膠化水性媒體之能力的低分子化合物所成群選出之一種或二種以上化合物所成之噴霧用基劑者。
