In 1970, these products had a sales volume of 57.3 million units, of which about 85% were windshield de-icers (4.5% carbon dioxide [CO2] or nitrous oxid [N2O]) and engine starting fluids (9.1% CO2). The modest production volume was marketed by the Union Carbide Corp., Radiator Specialty Co., Turtle Wax,...
