STOT-single exposure
The substance is irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. The substance may cause effects on the central nervous system.
STOT-repeated exposure
The substance defats the skin, which may cause dryness or cracking.
Aspiration hazard
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

Persistence and degradability
Data specific to the rate of environmental biodegradation of 2-methyl-1-butanol were not located. However, many biodegradation studies have demonstrated that the lower molecular weight aliphatic alcohols that are similar in structure to 2-methyl-1-butanol (such as 2-methyl-1-propanol) are readily biodegradable(1-11). This analogy indicates that 2-methyl-1-butanol is also likely to be readily biodegradable in the environment(SRC).
Bioaccumulative potential
Based upon a water solubility of 30,000 mg/l at 25 deg C(1), the BCF for 2-methyl-1-butanol can be estimated to be 1.8 from a regression-derived equation(2,SRC). Based upon a measured log Kow of 1.29(3), the BCF for 2-methyl-1-butanol can be estimated to be 5.6 from a regression-derived equation(2,SRC). These BCF values suggest that 2-methyl-1-butanol will not bioconcentrate significantly in aquatic organisms(SRC).
Mobility in soil
Based upon a water solubility of 30,000 mg/l at 25 deg C(1), the Koc for 2-methyl-1-butanol can be estimated to be 15 from a regression-derived equation(2,SRC). Based upon a measured log Kow of 1.29(3), the Koc for 2-methyl-1-butanol can be estimated to be 120 from a regression-derived equation(2,SRC). These BCF values suggest that 2-methyl-1-butanol has high to very high soil mobility(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
