    when you say demi-permanent, do you mean a direct dye (applied straight to the hair) or an oxidative dye (mixed with a developer prior to aplication)?

    the former would be very messy in an aerosol can, and the latter would be extremely impractical to use in an aerosol format

    Demipermanent is usually referred to as oxidative color without ammonia and with a low % peroxide. Since there are 2-components this is only possible with some kind of dual aerosol system (rare on the market). If you mean semipermanent/ temporary hair dye mousse it is quite straight forward.
