SECTION 2: Hazards identification

3.1 EMERGENCY OVERVIEW Specific Physical Form: liquid Odor, Color, Grade: clear, colorless, with slight ethereal odor. General Physical Form: Liquid Immediate health, physical, and environmental hazards:

Potential health effects

Eye Contact: Contact with the eyes during product use is not expected to result in significant irritation. Skin Contact: Contact with the skin during product use is not expected to result in significant irritation. Inhalation: If thermal decomposition occurs: May be harmful if inhaled. Ingestion: No health effects are expected.

Environmental effects

This substance has chemical moieties that are resistant to biodegradation and is likely to only undergo partial biodegradation in the environment. The high potential of this substance to move from water to the atmosphere means its potential to bioconcentrate is likely to disappear rapidly from aerobic environments. Take precautions to prevent direct release of this product to the environment. AQUATIC TOXICITY: Testing results indicate that this product has insignificant toxicity to aquatic organisms at its saturation point (Lowest LC50, EC50, or IC50 > substance water solubility). This substance is highly volatile and has a high Henry's Law constant and is thus expected to move rapidly through vaporization from solution in an aquatic compartment or from a soil surface in a terrestrial compartment to the atmosphere. ATMOSPHERIC FATE: Zero Ozone Depletion Potential (ODP). Atmospheric Lifetime: approximately 4.7 yr and 3.7 yr for n-butyl and isobutyl isomers, respectively. Global Warming Potential (GWP): 320 (100 year ITH, WMO 1998 method). Atmospheric degradation products are expected to include for methyl nonafluoroisobutyl ether predominantly iso-perfluorobutyric acid, CO2, HF, and perhaps also CF3COOH; for methyl nonafluorobutyl ether; n-perfluorobutyric acid, CO2, and HF. NOTE: The environmental data and statements provided on this document apply to methyl nonafluoroisobutyl ether and methyl nonafluorobutyl ether only. Environmental data have not been determined for the fluoroaliphatic polymer.
