Highly Flammable

ETHYL PROPIONATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can react with oxidizing agents, bases, and acids. Polymerization: Will not polymerize (USCG, 1999).

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

REPORTED FOUND IN SEVERAL TYPES OF WINE, IN WHITE GRAPE VAR SAUVIGNON AND IN COCOA.|Ethyl propionate is a common volatile found in certain fresh strawberries, citrus fruits and juices(1-7). It may also be formed during the growth of molds from damp buildings(1).

Ethyl propionate's production and use as a solvent, industrial process chemical, and flavoring agent(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 12(SRC), determined from a structure estimation method(2), indicates that ethyl propionate is expected to have very high mobility in soil(SRC). Volatilization of ethyl propionate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.5X10-4 atm-cu m/mole(SRC), from its vapor pressure, 35.8 mm Hg(4), and water solubility, 1.92X10+4 mg/l(3). The potential for volatilization of ethyl propionate from dry soil surfaces may exist(SRC) based upon a vapor pressure of 35.8 mm Hg(4). Biodegradation in soil is expected to be an important environmental fate process because of the presence of an easily biodegraded ester functional group(5).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 12(SRC), determined from a structure estimation method(2), indicates that ethyl propionate is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.5X10-4 atm-cu m/mole(SRC), from its vapor pressure, 35.8 mm Hg(4), and water solubility, 19,200 mg/l(7). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 6 hrs and 5 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 1.7(SRC), from its log Kow of 1.21(6) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low. Biodegradation in water is expected to be an important environmental fate process because of the presence of an easily biodegraded ester functional group(8).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethyl propionate, which has a vapor pressure of 3.58X10+1 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl propionate 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 7 days(SRC), calculated from its rate constant of 2.14X10-12 cu cm/molecule-sec at 25 °C(3).

The rate constant for the vapor-phase reaction of ethyl propionate with photochemically-produced hydroxyl radicals is 2.14X10-12 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 7 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A base-catalyzed second-order hydrolysis rate constant of 8.9X10-2 L/mol-sec(2) corresponds to half-lives of 2.5 yrs and 90 days at pH values of 7 and 8, respectively(3).

An estimated BCF of 1.7 was calculated for ethyl propionate(SRC), using a log Kow of 1.21(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.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for ethyl propionate can be estimated to be about 12(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethyl propionate is expected to have very high mobility in soil.

The Henry's Law constant for ethyl propionate is estimated as 2.51X10-4 atm-cu m/mole(SRC) from its vapor pressure, 35.8 mm Hg(1), and water solubility, 19,200 mg/l(2). This Henry's Law constant indicates that ethyl propionate is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 6 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 5 days(SRC). Ethyl propionate's estimated Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of ethyl propionate from dry soil surfaces may exist(SRC) based upon a vapor pressure of 35.8 mm Hg(1).

DRINKING WATER: Ethyl propionate was detected, not quantified in an English surface water sample (lowland river, location not specified) from which drinking water is derived(1).|SURFACE WATER: Ethyl propionate was detected, not quantified, in the Richenbach East Brook, which flows into Lake Constance in southwest Germany(1).

Ethyl propionate was detected at 0.20, 0.19, and 0.13 mg/100 ml in unprocessed, reverse osmosis processed, and water diluted whiskeys, respectively(1). The compound was also detected, not quantified, in headspace analyses of Sivetta variety strawberry samples held in a closed system(2). Ethyl propionate was one of the 27 volatile components identified, at a relative amount of 0.4%, in ripe Kiwi fruit from New Zealand and Australia(3). It is a volatile component of fresh grape fruit juice 0.0068 ppm(4), guava - 57.4 and 84.5 ug/kg in mature and overripe fruit, respectively(5). The compound was also identified as one of the 46 volatile components of both hand and mechanically extracted fresh orange juice from five different cultivars at a concn range of 0.0038 to 0.28 ppm(6). It has been identified not quantified in Concord grape essence(7) and as a volatile component of fresh, tree-ripened nectarines(8). Ethyl propionate was identified as a volatile in Italian-type dry-cured ham from a factory in Langhirano, Italy during processing at the following concns (day, condition, (mean concn in ng dodecane equiv)): 3, prior to salting, (0); 25, day dry salting, (0); 125, drying, (0); 211, first ripening, (1); 365, fully mature product (2); 485, post ripening, (3); not specified, spoiled sample, (41)(9).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 374 workers are potentially exposed to ethyl propionate in the US(1). Occupational exposure to ethyl propionate may occur through inhalation and dermal contact with this compound at workplaces where ethyl propionate is produced or used(SRC). The general population may be exposed to ethyl propionate via iingestion of food and dermal contact with consumer products containing ethyl propionate(SRC).

Results from the National Human Adipose Tissue Survey (NHATS) show that ethyl propionate was identified, not quantified, in 29 total adipose tissue samples, occurring in 4 samples from age group 0-14 yrs, 12 samples in age group 15-44, and 13 samples in age group 45 and older(1). Eleven samples from the US North Central region were positive, as were 4 from the Northeast, 12 from the South, and 2 from the West(1).

Exposure can cause irritation of eyes, nose and throat. May cause shortness of breath or coughing. High concentrations have a narcotic effect. May cause abdominal pain and vomiting if swallowed. (USCG, 1999)

Get medical attention. INHALATION: Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen. EYES: Flush with water for at least 15 min., lifting lids occasionally. Contact lenses should not be worn when working with this chemical. SKIN: Remove contaminated clothing and shoes. Wash with soap and water. (USCG, 1999)
