Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters

METHYL BENZOATE 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. This compound reacts with strong oxidizing agents and strong bases and hydrolyzes slowly in contact with water. (NTP, 1992).

In a comprehensive survey of wastewater from 4000 industrial and publicly owned treatment works (POTWs) sponsored by the Effluent Guidelines Division of the U.S. EPA, methyl benzoate was identified in discharges of the following industrial category (positive occurrences, median concn in ppb): nonferrous metals (1; 51.0), organics and plastics (2; 407.4), inorganic chemicals (1; 6.0), textile mills (1; 17.1), plastics and synthetics (2; 5727.5), rubber processing (2; 164.8), pharmaceuticals (1; 286.6), electronics (1; 142.1), organic chemicals (2; 953.1), publicly owned treatment works (2; 10.2). The highest effluent concn was 11,444 ppb in the plastics and synthetics industry(1).|Methyl benzoate was identified in the raw effluent of a polyester textile finishing plant(1). Methyl benzoate was present in the effluent of stack emissions from Ames power plant in Iowa, a coal-burning power plant, monitored for 4 years starting in 1977(2). Methyl benzoate was detected in effluent concentrates from the advanced treatment plant in Lake Tahoe, CA, but not in that of five other communities(3). Methyl benzoate was detected in the emissions of a municipal incineration plant at 0.12 ug/cu m, the location and date were not reported(4). The compound is a by-product of ozonolysis of a surface water source(5) and may be released during purification of water. Methyl benzoate may be released in stack emissions of coal burning plants(6).

SEDIMENT: Methyl benzoate was listed as tentatively detected in sediments from North Fork Elk River above mouth near Clark, CO and Fourmile Creek near Deckers, CO at concentrations of 1.67 and 65.9 ug/kg, respectively, in a USGS water quality study conducted over 5 years starting in 2003(1).

SOURCE DOMINATED: Methyl benzoate was detected but not quantified in ambient air and source air samples collected from Thane Belapur Industrial Area in Mumbai, India, which has various petrochemical, chemical, pharmaceutical, engineering, plastics industries with working facilities. Samples were taken at 16 locations during summer, monsoon, and winter seasons of 2004(1).

Methyl benzoate is reported as a component in tobacco, tobacco smoke, and tobacco substitute smoke(1). Methyl benzoate was detected in alfalfa silage emissions from a commercial dairy located in Yolo County, California at a concentration of 0.61 nL/L, sample collection date not reported(2). Methyl benzoate was detected in the emissions of 7 of 44 chamber samples of wood-based materials treated with commercially available lacquers and foils for furniture coatings(3). Methyl benzoate was identified in weathered, black crusted limestone from Sevilla Cathedral in Spain and Mechelen Cathedral in Belgium(4).

IDENTIFICATION AND USE: Methyl benzoate is a colorless, transparent liquid. It is used in perfumery, as a solvent for cellulose esters and ethers, resins, rubber, and as a flavoring. It is also used as a dye carrier for dyeing polyester fibers, additive for disinfectants, soy sauce, and pesticides. Methyl benzoate is an intermediate in the production of other benzoic esters. HUMAN EXPOSURE AND TOXICITY: Humans using methyl benzoate have experienced irritation to the skin, eyes, mucous membranes, and upper respiratory tract. Inhalation can cause coughing and wheezing. Swallowing the liquid may cause chemical pneumonia. A maximization test was carried out on 25 volunteers. Methyl benzoate was tested at a concentration of 4% in petrolatum and produced no sensitization reactions. Generally, methyl benzoate is of low to moderate toxicity by ingestion and inhalation. ANIMAL STUDIES: Sublethal doses of methyl benzoate have been reported to increase leucocyte, erythrocyte, and reticulocyte counts and prothrombin time, and in a dose of 500 mg/kg, to reduce cholinesterase activity and ascorbic acid levels. Chronic admin of high doses resulted in damage to the central nervous system. In nonoccluded skin irritation test carried out on clipped rabbits, no signs of erythema were observed in any of the animals (14/14), 4 and 24 hr after the application of 0.5 mL undiluted methyl benzoate. Very slight erythema was observed in the remaining (12/12) rabbits 24 hr after a second application. Redness increased with successive treatments. Moderate to severe edema was observed in animals (4/4) receiving 6 applications. Methyl benzoate received a score of 1 (out of 10) in a rabbit corneal necrosis test, indicating that it causes minimal eye injury. In an Ames test using Salmonella typhimurium (TA97, TA98, TA100, TA1535, and TA 1537), methyl benzoate (6666 ug/plate) was not mutagenic with or without metabolic activation.

Methyl benzoate occurs in oils of clove, ylang ylang, and tuberose(1,2). It occurs naturally in plants, flowers(3) and some fruit(4-5) and is produced by microorganisms(6).

Methyl benzoate's production and use in cosmetics and personal care products(1), as a dye carrier for dyeing polyester fibers(3-5), as an additive for disinfectants, soy sauce, and pesticides; perfume manufacturing; solvent for cellulose esters and ethers, resins and rubber; and as a flavoring(4-6) may result in its release to the environment through various waste streams(SRC). It is also a by-product of ozonolysis of a surface water source(3) and may be released during purification of water. Methyl benzoate may be released in stack emissions of coal burning plants(7).

TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 95-178(2-3) indicate that methyl benzoate is expected to have high to moderate mobility in soil(SRC). Volatilization of methyl benzoate from moist soil surfaces may be an important fate process(SRC) given a Henry's Law constant estimated as 3.24X10-5 atm-cu m/mole(SRC) based upon its vapor pressure, 0.38 mm Hg(4), and water solubility, 2.1X10+3 mg/L(5). Methyl benzoate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.38 mm Hg at 25 °C(4). Using a Modified Sturm test, methyl benzoate achieved 62% biodegradation in activated sewage sludge after 29 days(6), suggesting that biodegradation is an important environmental fate process in soil(SRC).|AQUATIC FATE: Based on a classification scheme(1), Koc values of 95-178(2-3) indicate that methyl benzoate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant estimated as 3.24X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 0.38 mm Hg(4), and water solubility, 2.1X10+3 mg/L(5). Using this Henry's Law constant and an estimation method(6), volatilization half-lives for a model river and model lake are 22 hours and 14 days, respectively(SRC). According to a classification scheme(7), an estimated BCF of 12(SRC), its log Kow of 2.12(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Using a Modified Sturm test, methyl benzoate achieved 62% biodegradation in activated sewage sludge after 29 days(10), suggesting 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), methyl benzoate, which has a vapor pressure of 0.38 mm Hg at 25 °C(2), will exist solely in the vapor phase in the ambient atmosphere. Vapor-phase methyl benzoate 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 38 days(SRC), calculated from its rate constant of 8.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Methyl benzoate 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).

The rate constant for the vapor-phase reaction of methyl benzoate with photochemically-produced hydroxyl radicals has been reported as 8.66X10-13 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 18.5 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(SRC). In a survey of photochemical reactivity among solvents, methyl benzoate ranked in the lowest category in terms of oxidant production and time to oxidize NO to NO2(2) and reactivity toward hydroxyl radicals(3). The hydrolysis of methyl benzoate is both base and acid catalyzed; the base catalyzed reaction is faster than the acid catalyzed reaction(4). The second order alkaline hydrolysis rate for methyl benzoate in water of 7.87X10-2 L/mol-sec, indicates a half-life of 10 days at pH 9 and 2.8 yr at pH 7(5). A base-catalyzed second-order hydrolysis rate constant of 4X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(6); this corresponds to half-lives of 5 years and 200 days at pH values of 7 and 8, respectively(6). Methyl benzoate does not contain chromophores that absorb at wavelengths >290 nm(7) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 12 was calculated in fish for methyl benzoate(SRC), using a log Kow of 2.12(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).

125.89 L/kg|The adsorption of methyl benzoate was determined by a modified version of the OECD guideline 106, a batch equilibrium method, in three soils with different characteristics: an acid forest soil (Podzol), an agricultural soil (Alfisol), and a sediment. The respective Freundlich constants, Kf (1/n), for the three soils were 8.64 (0.81), 1.29 (0.85), and 1.51 (0.84)(1). Koc values for the Podzol, Alfisol and sediment were 178, 103, and 95, respectively(1). Methyl benzoate also has a reported log Koc value of 2.10 (Koc = 126)(2). Using a structure estimation method based on molecular connectivity indices(3), the Koc of methyl benzoate can be estimated to be 70(SRC). According to a classification scheme(3), methyl benzoate is expected to have moderate to high mobility in soil.

The Henry's Law constant for methyl benzoate is estimated as 3.24X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 0.38 mm Hg(1), and water solubility, 2.1X10+3 mg/L(2). This Henry's Law constant indicates that methyl benzoate 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 22 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 14 days(SRC). Methyl benzoate's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Methyl benzoate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.38 mm Hg(1).

GROUNDWATER: Methyl benzoate was not detected in groundwater surveyed in England between 1977 and 1979(1).|DRINKING WATER: Tap water from the Kitakyushu Municipal Institute of Environmental Health Sciences in Japan had detectable concentrations of methyl benzoate of 1.8 ppb, sampled in 1980(1). EPA water supply data as of November 25, 1974 lists methyl benzoate as identified but not quantified in drinking water from New Orleans, LA(2). Methyl benzoate was detected in the treated waters from 7 of 14 water supplies surveyed in England between 1977 and 1979. Five of the water samples with methyl benzoate detections were collected from surface river waters, one from an upland reservoir and one from potentially polluted groundwater source. Methyl benzoate was detected in the treated waters only and not in the raw water samples examined(3). Methyl benzoate was detected in drinking water in China near areas irrigated by sewage effluent(4). Methyl benzoate was identified in drinking water concentrate from the Cincinnati, OH, water supply, but not in samples from six other US cities(5,6).|SURFACE WATER: Methyl benzoate was identified (major GC peak), but not quantified, in water samples from Spirit Lake, Castle Lake, and Smith Creek, 2.5 to 3 months after the eruption of Mount St Helens on May 18, 1980(1). The compound was identified not quantified in river water in Japan(2). Methyl benzoate was not detected in surface river water surveyed in England between 1977 and 1979(3).|SEAWATER: Methyl benzoate was was identified not quantified in sea water in Japan(1).

Methyl benzoate has been identified in ripening kiwi fruit(1), pineapple guava(2), clove oil(3), and a gruyere-type cheese from the Swiss Alps(4).

According to the 2012 TSCA Inventory Update Reporting data, 3 reporting facilities estimate the number of persons reasonably likely to be exposed during the manufacturing, processing, or use of methyl benzoate in the United States may be as low as <10 workers and as high as 49 workers per plant; the data may be greatly underestimated due to confidential business information (CBI) or unknown values(1).|NIOSH (NOES Survey 1981-1983) has statistically estimated that 73,641 workers (25,030 of these are female) were potentially exposed to methyl benzoate in the US(1). Based on results from an environmental survey conducted prior to 1991, occupational exposure to methyl benzoate may occur during the production of dimethyl terephthalate; concentrations of methyl benzoate were detected in the breathing zone and select areas of a plant manufacturing dimethyl terephthale(2). Occupational exposure to methyl benzoate may occur through inhalation and dermal contact with this compound at workplaces where methyl benzoate is produced or used. Monitoring and use data indicate that the general population may be exposed to methyl benzoate via ingestion of food and inhalation and dermal contact with consumer products containing methyl benzoate. (SRC)|A German survey performed in 1990 and 1991 of 113 people (ages 25-69) investigated personal atmospheric exposures for 1 week; methyl benzoate was detected at an average concentration of 1.8 ug/cu m (geometric mean) and 35 samples were less than 0.7 ug/cu m(1).
