Mother's milk from 4 urban areas in the USA, 1 of 8 samples tested positive for ethyl acetate(1). 7 out of 12 breath samples collected from nine volunteers in Bayonne and Elizabeth, NJ between July and Dec 1980 contained ethyl acetate at unreported concentrations(2). Ethyl acetate was identified as a component in 13.7% of expired air samples from 54 volunteers in the Chicago area at a geometric mean concentration of 0.447 ng/L(3). Ethyl acetate was detected in expired air samples from 5 of 8 male volunteers at levels ranging from 0.30 to 190.0 ug/hr(4). Five out of 8 personal air samples collected from volunteers in Bayonne and Elizabeth, NJ between July and Dec 1980 contained ethyl acetate at unreported concentrations(5).

Study of 30 workers exposed chronically to 15-50 mg of ethyl acetate in addition to 20 to 80 mg of amyl acetate/L of air showed no ... abnormalities in cornea, merely hyperemia of bulbar conjunctiva. ... Prolonged inhalation may be damaging to lung, liver, kidney, & heart. ... No effect on eyes ... known from systemic absorption.

Ethyl acetate in combination with toluene appeared to produce a mixture of lower toxicity than that of either compound alone. Mixing of ethyl acetate with propylene oxide, propylene glycol, or formalin appears to decr its LD50 value, but its toxicity increases in combination with morpholine, ethylene glycol, or ethyl alcohol.

In order to determine the lung disease potential of waterproofing sprays, several components of suspected sprays, as well as a commercial spray, were tested on CD-l-mice. Mice placed in inhalation chambers were exposed to aerosols containing one or more of the suspected components, including n-heptane, ethyl-acetate, fluororesin, silicone, and a commercial spray. An intermittent inhalation methods was used to prevent the solvents from causing anesthetic death. Mice were sacrificed 1 hour after the end of exposure. The lungs of both exposed and control mice were isolated and examined microscopically for any changes. The amounts released of the were similar. Mice exposed to the commercial and fluororesin sprays were cyanotic and depressed for 1 hour, while those exposed to the other sprays were cyanotic for only several minutes. In almost all mice exposed to the commercial spray, significant changes relative to the controls included a thickened pulmonary alveolar septa, cellular infiltration, fused and hemorrhaged alveolar walls, and diminished alveoli. Fluororesin particles were found in the alveolar space. Significantly more pronounced pathological changes were discovered in mice exposed to the fluororesin spray, relative to the commercial spray. In mice exposed to the silicone spray, significant differences were observed in alveolar collapse and hemorrhage, compared to the controls. The lungs of mice exposed to the N-heptane, ethyl-acetate, and fluororesin free sprays were similar to control lungs. In mice exposed to the silicon resin free spray, significant changes, relative to the commercial spray group, included alveolar collapse, hyperemia, hemorrhage and increased thickness and cellular infiltration of the septum. /It was/ concluded that ethyl-acetate and n-heptane contained in waterproofing sprays do not cause pulmonary disorders. Instead, fluororesin is implicated in respiratory disorders caused by such sprays.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 18(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that ethyl acetate is expected to have very high mobility in soil(SRC). Volatilization of ethyl acetate from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.34X10-4 atm-cu m/mole(4). Ethyl acetate is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 93.2 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 95% 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 18(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that ethyl acetate 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 1.34X10-4 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 9 hrs and 6 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, 95% 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), ethyl acetate, which has a vapor pressure of 93.2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl acetate 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 9 days(SRC), calculated from its rate constant of 1.6X10-12 cu cm/molecule-sec at 25 °C(3). Ethyl acetate 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).

Ethyl acetate forms from the reaction of acetyl coenzyme A with ethanol, and its formation depends greatly on temperature. Maximum formation occurs at 20-25 °C. Therefore, top fermented beers contain higher amounts of this ester.

Ethyl acetate is found in USA lager beer, 25 to 50 ppm(1). It is a component of Orleans vinegar(2) and artificial grape flavoring(3). Ethyl acetate was identified as a volatile component of roasted filberts(4), fried bacon(5), Beaufort cheese(6), blue cheese(7), Idaho Russet Burbank baked potatoes(8), and the edible Korean chamchwi plant(9). Korean salt-fermented anchovy, big-eyed herring, hair tail viscera and shrimp pastes contained ethyl acetate at mean concentrations of 3490, 1660, 2340, and 3750 ng/g, respectively(10). Ethyl acetate was detected in beer at a concentration of 8 ppm(11). Ethyl acetate was identified as a volatile compound in kiwi fruit, comprising 3.9, 4.7, and 1.6% of the components in mature, ripe, and very ripe fruit, respectively(12). It was also identified as a volatile component of pineapple guava at a concentration of 0.11 ug/g(13). Fresh grapefruit juice contained 1.65 ppm ethyl acetate(14). Ethyl acetate was identified in mature and overripe guava fruits at concentrations of 614.1 and 8884.2 ug/kg, respectively(15). It was identified as a volatile flavor component of the strawberry variety Sivetta and in Golden Delicious apples(16).

Ethyl acetate was identified as a volatile component of duck meat, duck fat, Cantonese style roasted duck, and Cantonese style roasted duck gravy at concentrations of <0.05, 2.43, 23.94, and <0.05 ppb wet weight, respectively(1). It was identified as a volatile compound in fried chicken flavor(2), nectarines(3), Concord grape essence(4), three Conn Creek wines(5), Sukiyaki(6), bananas(7), and floured Chickpea seed(8). Ethyl acetate was detected in fresh hand-squeezed (mechanically) unpasteurized orange juice from five different cultivars and one hybrid at concentrations of, ppm: 0.28 (0.15 to 0.25) in Valencia oranges; 0.17 to 0.23 (0.15) in Pineapple oranges; 0.12 to 0.13 in Hamlin oranges; 0.77 in Florida navel oranges; 0.17 in California navel oranges; 0.28 in Pera oranges; and 0.12 (0.082) in Ambersweet oranges(9). Large amounts of ethyl acetate were detected in headspace from Bisbee Delicious apples at the earliest harvests(10).

Ethyl acetate was detected, not quantified as a flavor volatile of Korean red pine (Pinus densiflora) sprout tea and pine needle tea; needles were collected in May to June 1995(1). It is a volatile constituent from the leaves of Callicarpa japonica Thunb. /Japanese beautyberry/, a member of the Verbenaceae family native to Korea, Japan, China and Taiwan(2).

IDENTIFICATION AND USE: Ethyl Acetate is a colorless liquid with a smell similar to glue or nail polish that is used as an industrial solvent. Ethyl Acetate is used as a solvent for chemical reactions. Because of its odor it is often used in cosmetics and its smell is associated with nail polishes. Additionally, it is used in confectionery, perfumes, and fruits because it evaporates at a fast rate, leaving but the scent of the perfume on the skin. Ethyl acetate is an effective poison for use in insect collector as its vapors are a respiratory tract irritant whose vapors can kill the insect quickly without destroying it, leaving it intact for study. HUMAN EXPOSURE AND TOXICITY: Short-term exposure to high levels of ethyl acetate results first in irritation of the eyes, nose and throat, followed by headache, nausea, vomiting, sleepiness, and unconsciousness. High concentrations can cause CNS depression and congestion of the liver and kidneys. Chronic poisoning has been described as producing anemia, leucocytosis (transient increase in the white blood cell count), and cloudy swelling, and fatty degeneration. Runners were evaluated after complaining of wheezing coughing, rhinitis, or shortness of breath after practicing in a facility under construction. Investigation revealed levels of ethyl acetate and toluene low enough to meet federal guidelines but apparently sufficient to cause symptoms in the athletes. Its carcinogenic properties are not known. Workers who in earlier years had been exposed to ethyl acetate concentrations of 300 mL/cu m and who were exposed at the time of the investigation to 16 mL/cu m were found to have normal sperm quality. ANIMAL STUDIES: In animals it has a narcotic effect at concentrations of over 5000 ppm. Repeated exposures of rabbits to 4450 ppm for 1 hr daily for 40 days resulted in anemia with leukocytosis, and damage to liver and kidneys. Male rats exposed to a high dose (3600 mg/kg/day) of ethyl acetate by gavage showed significan

/AQUATIC SPECIES/ Exposure of the fish /common Indian catfish, Heteropneustes fossilus/ to 170 ppm of ethyl acetate for 3, 6, 12, 48, and 96 hr induced marked changes in carbohydrate metabolism. Hepatic glycogen levels declined significantly at 3, 48, and 96 hr, but there was no marked alteration in muscle glycogen content at any of the exposure periods. Hyperglycemia occurred at all time intervals. Blood pyruvate levels were elevated at 3, 6, 48, and 96 hr. Hyperlacticemia resulted at 3 and 96 hr, but hypolacticemia occurred at 6 and 12 hr. Impairment of carbohydrate metabolism might be responsible for the toxic action of ethyl acetate.

Ethyl acetate presence in plants(1).[Table#248]

Ethyl acetate was identified as a volatile component of kiwi fruit flowers(1). Volatile emissions from Scots pine were found to contain ethyl acetate(2).

The feed additive ethyl alcohol containing ethyl acetate meets the requirement of 27 CFR 21.62, being not less than 92.5 percent ethyl alcohol, each 100 gallons having had added the equivalent of 4.25 gallons of 100 percent ethyl acetate. It is used in accordance with good feeding practices in ruminant feed supplements as a source of added energy.

U112; As stipulated in 40 CFR 261.33, when ethyl acetate, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5).

F003; When ethyl acetate is a spent non-halogenated solvent, it is classified as a hazardous waste from a nonspecific source (F003), as stated in 40 CFR 261.31, and must be managed according to State and/or Federal hazardous waste regulations.

Residues of ethyl acetate are exempted from the requirement of a tolerance when used in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only. Use: solvent, cosolvent.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer saftey standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Ethyl acetate is found on List D. Case No: 4005; Pesticide type: insecticide, herbicide, antimicrobial; Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Ethyl acetate; AI Status: The active ingredient is no longer contained in any registered pesticide products ...

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Ethyl acetate is produced, as an intermediate or final product, by process units covered under this subpart.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

... The current study was aimed at quantitating the extent of metabolism of inspired ethyl acetate in the upper respiratory tract (URT) of the F344 rat and Syrian hamster. Ethyl acetate deposition was measured in the surgically isolated URT of these species under constant velocity unidirectional flow conditions. The degree of metabolism was estimated by mathematic modeling based on a simple venous-equilibration approach and by direct comparison of deposition efficiencies in naive and carboxylesterase-inhibited animals. Ethyl acetate deposition efficiencies averaged between 10 and 35% in the rat URT and 36 and 72% in the hamster. Carboxylesterase inhibition decreased deposition in both species. Both the modeling efforts and the direct comparisons between naive and inhibited animals indicated that significant amounts of the deposited ethyl acetate were metabolized in the URT of both species with the extent of metabolism being more pronounced in the hamster. Specifically, 40-65% of the deposited ethyl acetate was metabolized in the URT of the rat compared to 63-90% in the hamster. This first-pass metabolism (i) increased URT deposition efficiencies; (ii) led to production of high metabolite levels in URT tissues; and (iii) decreased the amount of parent ethyl acetate available for absorption into the bloodstream in the URT.

Because of the abundance of nonspecific esterases, one might expect the common solvent ethyl acetate (EtAc) to be hydrolyzed to ethyl alcohol (EtOH) in vivo. It would then be possible to demonstrate EtOH accumulation following exposure to EtAc vapor. Preliminary studies showed that rat blood incubated at 37 °C does hydrolyze EtAc to EtOH, with a half-time of approximately 65 min. Analyses were done by gas chromatography. To study this reaction in vivo, rats were anesthetized with pentobarbital, and cannulae were inserted into the femoral arteries. EtAc was injected ip as a 25% () solution in corn oil (1.6 g/kg) and blood samples were drawn periodically. Hydrolysis was very rapid in vivo, with a half-time estimated at 5-10 min. Inhalation studies were then carried out by exposing anesthetized rats to several concentrations of EtAc vapor via an endotracheal tube. When EtAc concentrations were increased above 2000 ppm, EtAc absorption exceeded EtOH oxidation, leading to an accumulation of EtOH in the blood. Although blood EtOH concentrations increased steadily to over 0.10 g/100 mL in 5 hr, EtAc remained consistently below 0.01 g/100 mL and did not change throughout the course of the experiment, again indicating rapid hydrolysis. The data indicate that EtOH will accumulate during exposure to EtAc if the ambient concentration of EtAc is sufficiently high.

... Ethyl acetate ... metabolism produces corresponding ethyl alcohol & is partly excreted in exhaled air & urine & partly metabolized.

Metabolic studies in the rat have revealed an approximate 2000 ppm no-effect level. At higher levels, the rate of hydrolysis of ethyl acetate appeared to exceed ethanol oxidation, leading to its accumulation in the vascular system. Also, when it was injected intraperitoneally at 1.6 g/kg, hydrolysis to acetic acid and ethanol occurred rapidly. Intraperitoneal injections of 1 mL/kg to male rats for 8 days increased the blood pyruvic and lactic acid content considerably and also elevated the glycolytic enzymatic activity.
