10.2 Chemical stability
Stable under recommended storage conditions.
10.3 Possibility of hazardous reactions
CombustibleETHOXY TRIGLYCOL is a ethoxy-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

12.2 Persistence and degradability
AEROBIC: In a mixture of triethylene glycol monoethyl ether and other higher homologs, BOD values 0, 7, and 8% of the theoretical BOD were reported for day 5, 10, and 20, respectively(1). A 5 day BOD test using acclimated mixed cultures resulted in an experimental BOD 69% that of the theoretical value(2). Triethylene glycol monoethyl ether was rapidly biodegraded in the BOD test with 38, 90, 94, and 100% degradation reported for 5, 10, 15, and 20 days, respectively(3). Filtered domestic fresh wastewater using non-acclimated seed gave biodegradation rates for triethylene glycol monoethyl ether of 8%, 47%, 63% and 71% in 5, 10,15 and 20 days, respectively(4). Filtered domestic salt wastewater using non-acclimated seed gave biodegradation rates for triethylene glycol monoethyl ether of 1%, 10%, 12% and 22% in 5, 10,15 and 20 days, respectively(4). A 5 day BOD test with effluent from a waste treatment plant at 20°C and non-acclimated seed gave a BOD of 0.05 g/g which was 3% of theoretical value of 1.89 g/g(4).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for triethylene glycol monoethyl ether(SRC), using an estimated log Kow of -0.96(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of triethylene glycol monoethyl ether can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethylene glycol monoethyl ether is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
