| 相互作用 | 2-ethoxyethanol, induced complete embryomortality in pregnant rats exposed to three times the current Federal permissible exposure limit (PEL). Following exposure to ethoxyethanol at a concentration only one-half the current PEL, the offspring evidenced behavioral and neurochemical deviations from controls. Subsequent studies found that ingestion of ethanol with concomitant inhalation of ethoxyethanol vapors early in pregnancy appeared to reduce the number of both behavioral and neurochemical deviations found for ethoxyethanol. In contrast, the concomitant exposure to ethanol and ethoxyethanol later in gestation potentiated the behavioral and neurochemical effects of ethoxyethanol. This research indicates that the industrial solvent 2-ethoxyethanol presents an occupational reproductive hazard and raises the issue of the importance of an interaction of social habits with occupational exposure to such hazards. The results would suggest that occupational physicians should advise pregnant workers in the chemical industry of the adverse effects of ethanol during pregnancy and of the possible interactions with other chemicals and should encourage them to be especially cautious with ethanol consumption since they may be at greater risk.Behavioral and neurochemical deviations in the offspring of rats exposed to 100 ppm ethoxyethanol during gestation have been reported previously. Since this compound is likely metabolized in the same manner as ethanol, the present study investigated the interactive effects of ethanol and ethoxyethanol on prenatal development. Groups of 15-20 pregnant Sprague-Dawley rats were given 10% ethanol in the drinking water with or without concomitant inhalation exposure to 100 ppm ethoxyethanol during gestation days 7-13 or 14-20. Another group was exposed to 200 ppm ethoxyethanol on gestation days 7-13, and sham-exposed controls were included for both gestation periods. Ethanol alone on days 14-20 and 200 ppm ethoxyethanol reduced overall weight gain during pregnancy. As in the previous research, pregnancy duration was extended in the groups given ethoxyethanol, but not in groups given ethanol alone. Neuromotor ability, as assessed by an ascent test and by a rotorod, was reduced by 200 ppm ethoxyethanol and by ethanol alone on gestation days 7-13. The group given ethanol plus ethoxyethanol on days 14-20 spent significantly longer in the start area of an open field, and this group as well as that given 200 ppm ethoxyethanol were less active than controls in the open field and in the shuttle box. When compared with previous research, it appears that ethanol early in gestation may reduce the effects, but later in gestation may enhance the effects of prenatal ethoxyethanol.Repeated exposure of workers to /2-Methoxyethanol/ (2-ME) and /2-Ethoxyethanol/ (2-EE), in addition to other solvents, resulted in anaemia, leucopenia, general weakness, and ataxia.Endocrine disrupting chemicals cause reproductive dysfunction by interacting with intricate regulation and cellular processes involve in spermatogenesis. This study investigated the probable mechanism of action of ethylene glycol monoethyl ether (EGEE) as an antiandrogenic compound as well as the effects of kolaviron upon co-administration with EGEE in rats. Adult male rats were exposed to EGEE (200 mg/kg bw) separately or in combination with either kolaviron [100 (KV1) and 200 (KV2) mg/kg bw] or vitamin E (50 mg/kg bw) for 14 days. Western blot analysis revealed that the administration of EGEE adversely affected steroidogenesis in experimental rats by decreasing the expression of steroid acute regulatory (StAR) protein and androgen-binding protein (ABP). EGEE significantly decreased the activities of 3beta-hydroxysteroid dehydrogenase (3beta-HSD) and 17beta-hydroxysteroid dehydrogenase (17beta-HSD) but markedly increased sialic acid concentration in rat testes. EGEE-treated rats showed significant decreases in plasma levels of luteinizing hormone (31%), testosterone (57.1%), prolactin (80.9%), triiodothyronine (65.3%) and thyroxine (41.4%), whereas follicle-stimulating hormone was significantly elevated by 76.9% compared to the control. However, co-administration of kolaviron or vitamin E significantly reversed the EGEE-induced steroidogenic dysfunction in rats. This study suggests that kolaviron may prove promising as a chemoprotective agent against endocrine pathology resulting from EGEE exposure. |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2(SRC), determined from a log Kow of -0.32(2) and a regression-derived equation(3), indicates that ethylene glycol monoethyl ether is expected to have very high mobility in soil(SRC). Volatilization of ethylene glycol monoethyl ether from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 4.7X10-7 atm-cu m/mole(4). Ethylene glycol monoethyl ether is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.31 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 76% of the Theoretical BOD was reached in 2 weeks(6) indicating that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2(SRC), determined from a log Kow of -0.32(2) and a regression-derived equation(3), indicates that ethylene glycol monoethyl ether is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon a Henry's Law constant of 4.7X10-7 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 74 and 540 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 76% of the Theoretical BOD was reached in 2 weeks(7) indicating that biodegradation is an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylene glycol monoethyl ether, which has a vapor pressure of 5.31 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol monoethyl ether 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 22 hrs(SRC), calculated from its rate constant of 1.54X10-11 cu cm/molecule-sec at 25 °C(3). Ethylene glycol monoethyl ether does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| 毒性の概要 | On the basis of the animal and clinical data included in this report, the CIR Expert Panel concludes that Ethoxyethanol and Ethoxyethanol Acetate are unsafe for use in cosmetic products.The ingredient is unsafe for use in cosmeticsIDENTIFICATION AND USE: Ethylene Glycol Monoethyl ether (EGEE) is a colorless liquid with mild, agreeable odor. It is used as a solvent for nitrocellulose, lacquers and dopesin varnish removers, cleansing solutions, dye bathsfinishing leather with water pigments and dye solutionsincreasing stability of emulsions. HUMAN EXPOSURE AND TOXICITY: Short-term exposure: The substance is mildly irritating to the eyes and respiratory tract, may cause effects on the central nervous system, blood, bone marrow, kidneys and liver. Exposure at high levels could cause unconsciousness. Long-term or repeated exposure: The liquid defats the skin, may have effects on the blood and bone marrow. The major long-term effects of exposure for humans are developmental, testicular, and hematological toxicity. A cross-sectional evaluation of semen quality was carried out in workers exposed to EGEE. A control group of workers from the same plant was included. Workers exposed to EGEE had significantly lower average sperm counts than controls, although both groups had lower sperm counts than those found in other occupational groups. In other study, hemoglobin, hematocrit, red cell indices, total and differential white blood cell counts, and platelet count were measured in shipyard painters and control subjects as part of a cross-sectional, observational study of the effects of ethylene glycol ethers. A significant proportion of painters were anemic (10%) and granulocytopenic (5%)none of the controls were affected. ANIMAL TOXICITY STUDIES: EGEE administered sc for 4 weeks at doses of up to 0.38 g/kg/day caused no deaths in rats.

説明
2-Ethoxyethanol is a stable, colorless, flammable liquid, synthetically produced throughout the world. It belongs to a larger group of glycol ether solvents. 2-Ethoxyethanol is commercially referred to as Ethyl Cellosolve or Cellosolve, a trademark registered by Union Carbide in 1924. It was first synthesized to have the same chemical properties of both alcohols and ethers (hydrophilic and lipophilic) but less volatile, which improves production characteristics. The glycol ethers are made by reacting anhydrous alcohols with ethylene oxide.
使用
2-Ethoxyethanol is widely used as an industrial solvent and production intermediate. It is produced by the reaction of ethylene oxide with ethanol. The glycol ethers are miscible in polar and nonpolar solutions, which make them useful solvents in paints and surface coatings, stains, lacquers, inks, and dyes. Additional uses include industrial deicing, hydraulic fluids, and cleaning agents. 2-Ethoxyethanol was once used in cosmetic products but is no longer used due to toxicity associated with dermal absorption. Global production has been on the decline in recent years based on demonstrated toxicity through oral, dermal, and inhalation routes of exposure. The use of ethylene glycol ethers has largely been replaced by relatively safer substitutes, primarily propylene glycol ethers; however, their use as a solvent and chemical process intermediate poses potential for release into the environment.
一般的な説明
