Absorption, Distribution and Excretion

To assist evaluation of the hazards of skin contact with selected undiluted glycol ethers, their absorption across isolated human abdominal epidermis was measured in vitro. Epidermal membranes were set up in glass diffusion cells and, following an initial determination of permeability to tritiated water, excess undiluted glycol ether was applied to the outer surface for 8 hr. The appearance of glycol ether in an aqueous receptor phase bathing the underside of the epidermis was quantified by a gas chromatographic technique. A final determination of tritiated water permeability was compared with initial values to establish any irreversible alterations in epidermal barrier function induced by contact with the glycol ethers. 2-methoxyethanol (EM) was most readily absorbed (mean steady rate 2.82 mg/sq cm/hr), and a relatively high absorption rate (1.17 mg/sq cm/hr) was also apparent for 1-methoxypropan-2-ol (PM). There was a trend of reducing absorption rate with increasing molecular weight or reducing volatility for monoethylene glycol ethers (EM, 2.82 mg/sq cm/hr; 2-ethoxyethanol, EE, 0.796 mg/sq cm/hr; 2-butoxyethanol, EB, 0.198 mg/sq cm/hr) and also within the diethylene glycol series: 2-(2-methoxyethoxy) ethanol (DM, 0.206 mg/sq cm/hr); 2-(2-ethoxyethoxy) ethanol (DE, 0.125 mg/sq cm/hr) and 2-(2-butoxyethoxy) ethanol (DB, 0.035 mg/sq cm/hr). The rate of absorption of 2-ethoxyethyl acetate (EEAc) was similar to that of the parent alcohol, EE. Absorption rates of diethylene glycol ethers were slower than their corresponding monoethylene glycol equivalents. Combination of intrinsic toxicity and ability to pass across skin contribute to assessment of hazards of contact with undiluted glycol ethers.[Dugard PH et al; Environ Health Perspect 57: 193-7 (1984)] Full text: PMC1568269

12.2Persistence and degradability

AEROBIC: Aerobic biological screening studies, which utilized settled wastewater, sewage, or activated sludge for inocula, indicate that diethylene glycol monoethyl ether should biodegrade rapidly in the environment following an acclimation period(1-6). After a 16 day acclimation period a 39.8% BODT was recorded using an 8 hr Warburg test(5). A 5 day BOD test at 20 deg C showed a 34.3% loss after 16 days of acclimation(5). A second 5 day BOD test, utilizing an adapted seed inoculum exhibited a 30% BODT(1). Incubation of diethylene glycol monoethyl ether for 5, 10, and 20 days without an acclimation period resulted in BOD values, measured in % theoretical, of 5, 31, and 48, respectively(2). Diethylene glycol monoethyl ether, inoculated with wastewater, was bio-oxidized 17, 71, 75, and 87% following 5, 10, 15, and 20 days incubation, respectively; in seawater, this compound was bio-oxidized 11, 44, 57, and 70% in 5, 10, 15, and 20 days, respectively(3). According to the Zahn-Wellens screening method >90% loss of 400 ppm occurred in 28 days(4). A study using activated sludge gave a degradation rate for diethylene glycol monoethyl ether of 0.18/hour(6) giving a half-life of 3.9 hours(SRC).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for diethylene glycol monoethyl ether(SRC), using a log Kow of -0.54(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).

12.4Mobility in soil

The Koc of diethylene glycol monoethyl ether is estimated as 12(SRC), using a log Kow of -0.54(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethylene glycol monoethyl ether is expected to have very high mobility in soil.

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
