Chemical: Ethanol, 2,2'-oxybis-, dibenzoate

Ethanol, 2,2'-oxybis-, 1,1'-dibenzoate is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Ethanol, 2,2'-oxybis-, 1,1'-dibenzoate are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

REACH registered substance: Oxydiethylene dibenzoate (EC: 204-407-6)

Ethanol, 2,2'-oxybis-, dibenzoate: Non hazardous

0 - Materials that, under emergency conditions, would offer no hazard beyond that of ordinary combustible materials.

1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur.

0 - Materials that in themselves are normally stable, even under fire conditions.

Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 540(SRC), determined from a structure estimation method(2), indicates that diethylene glycol dibenzoate will have low mobility in soil(SRC). Volatilization of diethylene glycol dibenzoate should not be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 3X10-12 atm-cu m/mole(SRC), using a recommended regression equation(3). Volatilization from dry soil surfaces(SRC) is not expected based on an estimated vapor pressure of 0.09 mm Hg(SRC), determined from a fragment constant method(4). No data are available to determine the rate or importance of biodegradation of diethylene glycol dibenzoate in soil(SRC).

AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 540(SRC), determined from a structure estimation method(2), indicates that diethylene glycol dibenzoate should adsorb to suspended solids and sediment in the water(SRC). Diethylene glycol dibenzoate will be essentially non-volatile from water surfaces(1,SRC) based on an estimated Henry's Law constant of 3X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). According to a classification scheme(5), an estimated BCF value of 120(1,SRC), from an estimated log Kow(4,SRC), suggests that bioconcentration in aquatic organisms is high(SRC). Diethylene glycol dibenzoate has an estimated base-catalyzed hydrolysis rate of 0.16 L/mol-sec at a pH of 8, which corresponds to a half-life of 49 days at a pH of 8 and 1.3 years at a pH of 7(6,SRC). Insufficient data are available to determine the rate or importance of biodegradation of diethylene glycol dibenzoate in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), diethylene glycol dibenzoate, which has an estimated vapor pressure of 0.09 mm Hg at 25 °C(2,SRC), will exist solely as a vapor in the ambient atmosphere. Vapor-phase diethylene glycol dibenzoate is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 20 hours(3,SRC). Particulate-phase diethylene glycol dibenzoate may be physically removed from the air by wet and dry deposition(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for diethylene glycol dibenzoate can be estimated to be about 540(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that diethylene glycol dibenzoate has low mobility in soil(SRC).

An estimated BCF value of 120 was calculated for diethylene glycol dibenzoate(SRC), using an estimated log Kow of 3.04(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is high(SRC).

The Henry's Law constant for diethylene glycol dibenzoate is estimated as 3X10-12 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that diethylene glycol dibenzoate will be essentially nonvolatile from water surfaces(2,SRC). Diethylene glycol dibenzoate's estimated values for vapor pressure, 0.09 mm Hg(3,SRC) and Henry's Law constant(1,SRC) indicate that volatilization from dry and moist soil surfaces should not occur(SRC).

The rate constant for the vapor-phase reaction of diethylene glycol dibenzoate with photochemically produced hydroxyl radicals has been estimated as 1.8X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 20 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). Diethylene glycol dibenzoate has an estimated base-catalyzed hydrolysis rate of 0.16 L/mol-sec at a pH of 8, which corresponds to a half-life of 49 days at a pH of 8 and 1.3 years at a pH of 7(2,SRC).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 25,414 workers (10,937 of these are female) are potentially exposed to diethylene glycol dibenzoate in the USA(1). Occupational exposure may be through inhalation and dermal contact with this compound(SRC).

Diethylene glycol dibenzoate's production and use as a plasticizer may result in its release to the environment through various waste streams. If released to soil, diethylene glycol dibenzoate will have low mobility based on an estimated Koc value of 540. Volatilization of diethylene glycol dibenzoate is not expected to be important from moist soil surfaces given an estimated Henry's Law constant of 3X10-12 atm-cu m/mole. Volatilization from dry soil surfaces is not expected based on an estimated vapor pressure of 0.09 mm Hg. Insufficient data are available to determine the rate or importance of biodegradation of diethylene glycol dibenzoate in soil or water. If released to water, diethylene glycol dibenzoate is expected to adsorb to suspended solids and sediment based on an estimated Koc value of 540.
