Description

Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century.

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill fish); Conditions: static bioassay, filtered tap water, temperature 20°C; Concentration: 1,000 mg/L for 96 hours.
  • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, age < or =24 hr); Conditions: freshwater, static, 20-22°C, pH 7.6-7.7; Concentration: 10000000 ug/L for 24 hr /formulated product
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Diethylene glycol, present at 30 mg/L, reached 90% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 100 mg/L in the Japanese MITI test(1). The compound, present at 100 mg/L, showed 59% (rate constant of 0.081/day, 5 day lag period) and 89% degradation (0.173/day, 5 day lag period) using the Sapromat and Oxitop systems, respectively, in manometric respirometry tests using activated sludge at 30 mg/L dry matter(2). Biodegradation of 44% and 78% degradation were reported when using seawater as inoculum in a shake flask die-away test (chemical concentration of 5-30 DOC/L) and the closed bottle oxygen consumption test (test chemical concentration of 2-10 mg/L), respectively, both incubated at 15-20°C for 28 to 60 days; however, high carbon levels may have compromised the test results(3).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for diethylene glycol(SRC), using an estimated log Kow of -1.5(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 diethylene glycol can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylene glycol 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.
