SECTION 2: Hazards identification

3.1 EMERGENCY OVERVIEW Specific Physical Form: liquid Odor, Color, Grade: clear colorless, very faint sweet odor General Physical Form: Liquid Immediate health, physical, and environmental hazards:

Potential health effects

Eye Contact: Mild Eye Irritation: Signs/symptoms may include redness, pain, and tearing. 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. 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 Oxone Depletion Potential (ODP). Atmospheric Lifetime: ~2.2 years (based on reaction with OH radicals) Global Warming Potential (GWP): 90 (100 year ITH) (IPCC1995 method) Global Warming Potential (GWP): 100 (100 year ITH) (IPCC2001 method)
