The subject of the invention is a pressurised aerosol formulation, which is in the form of a mixture, to be sprayed as a cosmetic, room or medicinal spray, of a propellant gas and organic solvents, as the propellant, and also active compounds and solvents for the active compounds, wherein the improvement comprises that the mixture is in the form of a homogeneous solution and this contains at least 50 percent by weight, preferably at least 55 percent by weight, of non-combustible constituents--relative to the total weight of the mixture--and contains, as the propellant gases, carbon dioxide and dimethyl ether, and, as non-combustible constituents, at least water, carbon dioxide, methylene chloride and/or 1,1,1-trichloroethane. This pressurized aerosol formulation is during transport, on storage and in use a product of low accident risk for the indicated purpose.
A pressurized aerosol formulation, which is in the form of a mixture, to be sprayed as a cosmetic, room or medicinal spray, of a propellant gas and organic solvents for the propellant gas, as the propellant, and also active compounds and solvents for the active compounds, wherein the mixture is in the form of a homogeneous solution and the solution contains at least 50 percent by weight of non-combustible constituents relative to the total weight of the mixture and contains, as propellant gases, carbon dioxide and dimethyl ether, and, as non-combustible constituents, at least water, carbon dioxide, methylene chloride, 1,1,1-trichloroethane, or a mixture of methylene chloride and 1,1,1-trichloroethane, wherein said organic solvents are selected from the group consisting of acetone, ethyl methyl ketone, diethyl ether, dimethoxymethane, diethyl carbonate, ethyl alcohol, n-propanol, isopropanol, methyl acetate, ethyl acetate, methoxyacetone, hydroxyacetone, methyl isopropyl ketone, diethyl ketone, diisopropyl ketone, dipropyl ketone, dichloroethylene, ethyl chloride, 1,1-dichloroethane, 1-chlorobutane, and mixtures thereof.
A sprayable, pressurized, aerosol formulation for use as a cosmetic, room or medicinal spray, said formulation comprising a homogeneous solution of
