Abstract
Abstract An aerosol composition comprising a liquid mixture of hydrocarbon propellant, an alcoholic solvent and, to reduce flammability, water and methylene chloride and/or 1,1,1-trichloroethane, wherein the liquid mixture forms a single phase consisting essentially of 5-30% by weight of the hydrocarbon propellant, 5-30% by weight of water, 10-40% by weight of methylene chloride and/or 1,1,1-trichloroethane, and 37-80% by weight of ethanol, n-propanol or iso-propanol. The composition does not require to be shaken before use.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
An aerosol composition within an aerosol container comprising a liquid mixture of a hydrocarbon propellant, water and an organic solvent, wherein the liquid mixture forms a single phase and consists essentially of: (a) about 5 to about 30% by weight of a hydrocarbon propellant to give a pressure within the aerosol container of 1.5 to 8.5 kg/cm 2 at 25° C.; (b) about 5 to about 30% by weight of water; (c) about 10 to about 40% by weight of a chlorinated solvent selected from the group consisting of methylene chloride and 1,1,1-trichloroethane; and (d) about 37 to about 80% by weight of an alcohol selected from the group consisting of ethanol, n-propanol and iso-propanol.
Claim 2
Dependent Claim
115 words
An aerosol composition within an aerosol container comprising a liquid mixture of a hydrocarbon propellant, water and an organic solvent, wherein the liquid mixture forms a single phase and consists essentially of: (a) about 5 to about 30% by weight of a hydrocarbon propellant to give a pressure within the aerosol container of 1.5 to 8.5 kg/cm 2 at 25° C.; (b) about 5 to about 30% by weight of water; (c) about 10 to about 40% by weight of a chlorinated solvent selected from the group consisting of methylene chloride and 1,1,1-trichloroethane; and (d) about 37 to about 80% by weight of an alcohol selected from the group consisting of ethanol, n-propanol and iso-propanol.
Claim 3
Dependent Claim
19 words

Claim 4
Dependent Claim
17 words
A composition as claimed in claim 1 comprising about 5 to about 20% by weight of water.
Claim 5
Dependent Claim
19 words
A composition as claimed in claim 1 comprising about 15 to about 30% by weight of the chlorinated solvent.
Claim 6
Dependent Claim
24 words
