A composition that can be used as carrier for substances including chemically, physically or biologically active products is constituted by two components that interact when they are expelled in converging directions from their respective containers by means of a propelling agent, generating in situ myriad particles or drops of very small size and with the capacity of maintaining themselves temporarily airborne while being transported by it, one of the components containing ammonia and mono (C1-4 alkyl) amine other than isopropylamine and/or a di(C1-2 alkyl) amine together with a compressible gas as propelling agent, the other component containing acetic acid and/or sulphur dioxide and a compressible gas as propelling agent. At least one of the components contains the said substance, and either or both of the components optionally contain at least one of water, glycols, silicone, oils, mineral oils, silica, sodium tetraborate, ferric chloride, talc and finely divided dolomite. |
