Abstract
Process for the production of aerosols, in suspension, improved, from one or more active substances hardly soluble in the propellant; of a propellant agent; of an emulsifier and, if necessary, aromatic and auxiliary substances, whose process is characterized by the fact that it reuses as an emulsifier a tenso-active substance, solid or unctuous, non-ionogenic, having a lower hydrophilic-lipophilic balance ratio to 10 and that it is only partially soluble in the propellant at room temperature; because the tensio-active substance dissolves, heating, in a fluid suitable for the manufacture of a solution because the active substance is mixed with this solution until the desired volume of the particles has been reached and the mixture is then supplemented with the dilution liquid until reaching a certain volume, packed in cans of aerosols and finally filling it with the liquefied propellant gas.
