The present invention relates to a nebulizer, such as a spray can, for the topical application of a liquid and/or solid to a surface. The nebulizer is characterized by a valve comprising a mixing chamber designed for forming a colloidal mixture comprising a dispersed phase consisting of a liquid and/or a solid substance and a continuous phase consisting of a propellant gas before delivering the colloidal mixture to the nozzle. The invention also relates to a method for the topical cooling of the skin of a person or animal. In addition, the invention relates to various other uses of the device.
