A pressurized carrier mixture for aerosol preparations of a self-propelling spray system, for use as a universal spray based on the active ingredients to be applied, organic solvents, water and propellants in a spray container. The carrier mixture is present as a homogeneous solution containing: 70.0-50.1 percent by weight of water; 38.5-28.7 percent by weight of dimethyl ether; 0.5-10.0 percent by weight of isopropanol and/or ethanol and/or n-propanol; and 1.4-0.8 percent by weight of carbon dioxide.

Pressurized carrier mixture for aerosol preparations

An aerosol can having a super-fine atomization valve, a process for its manufacture, and a process for introducing a filling which contains a propellant into the can. The can imparts a suitable fine division of droplets to the propellant medium which is to be sprayed. The can is suitable for the spraying of homogeneous mediums which do not contain chlorofluorinated hydrocarbons or hydrocarbon propellant gases.

A propellant composition which can be sprayed from a compressed gas container comprises a solvent or mixture of solvents having a vaporization number of about 1 to about 15 and a gaseous propellant absorption capacity of about 1 to about 15 weight percent at 20.degree. C. The solvent or mixture of solvents has a substantial portion of a gaseous propellant dissolved therein. The gaseous propellant is carbon dioxide. The propellant composition is suitable for use in compressed gas containers such as those employed with hairsprays, deodorant sprays, room sprays, etc.
