An aerosol device for dispensing a composition with relatively high viscosity, in particular a gel or an emulsion, comprises a can intended to be used with the head upwards, containing the composition and a propellant agent acting directly on the composition. A dispensing valve is in the upper part of the can on an opening of this can, while a dip-tube connected to the valve extends as far as the vicinity of the bottom of the can. The composition (C) to be dispensed has a viscosity (measured on a Brookfield DV III viscometer, needle no. 7) lying in the range of 4000 to 10,000 millipascal.second, preferably of 6000 to 8000 millipascal.second, for a speed of 100 revolutions/minute and of 30,000 to 150,000 millipascal.second, preferably of 50,000 to 120,000 millipascal.second, for a speed of 2.5 revolutions/minute. The dip-tube is a semi-capillary tube (18) whose internal diameter (e) lies between 0.7 and 1.5 mm.
