HONEYWELL SOLSTICE™ PROPELLANT IS NOT A VOC, EPA ANNOUNCES
EPA determination excludes Honeywell Solstice™ Propellant from list of volatile organic compounds, allowing aerosol formulators more options
MORRISTOWN, N.J., 22 June 2012 -- Honeywell
that the U.S. Environmental Protection Agency (EPA) has added Solstice™ Propellant (HFO-1234ze) to the list of compounds excluded from the definition of Volatile Organic Compounds (VOCs). The EPA based its decision on the propellant's low photochemical reactivity and negligible contribution to the generation of tropospheric ozone. The classification will help aerosol formulators develop products that meet federal VOC regulations, adding another key environmental benefit to the product's very low global warming potential. "The EPA's decision means that there is no longer an environmental trade-off required when selecting propellants. In the past, formulators had to choose between flammable propellants like hydrocarbons and dimethyl ether, which have low global warming potentials (GWPs) but are VOCs, or a nonflammable propellant, like HFC-134a, which is not a VOC but has a higher GWP," said Terrence Hahn, vice president and general manager of Honeywell Fluorine Products. "Now Honeywell's Solstice Propellant combines two highly desirable properties low GWP and non-VOC along with non-flammability, for a triple win for the environment."Honeywell's non-flammable, non-ozone depleting Solstice Propellant has a global warming potential of 6. It is an alternative to HFC-134a and HFC-152a, two propellants in common use today, which have GWPs of 1,430 and 124, respectively, as well as the flammable hydrocarbon propellants. Solstice Propellant can be used in various aerosol applications including personal and household care products, dusters, warning systems, industrial cleaners, novelty aerosol products and others. Tropospheric, or ground level, ozone is an irritant and a major component of photochemical smog. VOCs are organic compounds that break down quickly in the lower atmosphere and participate in chemical reactions that ultimately create tropospheric ozone. In addition to Solstice Propellant, Honeywell's family of Solstice-branded products includes stationary and mobile refrigerants, liquid and gaseous blowing agents, and solvents based on Honeywell's new hydrofluoro-olefin technology that helps customers lower their carbon footprint without sacrificing end-product performance. The products have been developed and are being commercialized by Honeywell's Fluorine Products business, a leader in the manufacture and supply of non-ozone-depleting refrigerants used by top air-conditioning and refrigeration makers worldwide, and blowing agents for energy-efficient foam insulation.For more information, please visit
