  • Patent number: 10273437
    Abstract: A solvent composition is provided that includes a chlorinated ethylene present from 75 to 80 total weight percent and at least one halocarbon miscible with the chlorinated ethylene and present in an amount to define a weight ratio of the chlorinated ethylene to said at least one halocarbon of from 75:25-80:20. The solvent composition has a flash point of less than 23 degrees Celsius and an initial boiling point of greater than 35 degrees Celsius. When the solvent is packaged as an aerosol with a propellant, the resulting solvent can be used in confined spaces owing to reduced ignitibility and better human health and environmental properties compared to conventional aerosol degreasers.
