Methyl Oleate is a fatty acid methyl ester resulting from the formal condensation of the carboxy group of oleic acid with methanol. It derives from an oleic acid.Methyl Oleate is exempted from the requirement of a tolerance when used as a surfacant in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only.Methyl Oleate is exempted from the requirement of a tolerance when used as a surfacant in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only.Methyl Oleate is an indirect food additive for use only as a component of adhesives.Methyl Oleate WAS TESTED FOR CARCINOGENICITY BY ORAL & SC ADMIN IN ST/A MICE OF BOTH SEXES, BUT A POSITIVE EFFECT COULD NOT BE ASSESSED.Methyl Oleate PROMOTED SKIN TUMOR FORMATION IN MICE. THE RELATION OF MOLECULAR CONFIGURATION & CARCINOGENICITY OF FATTY ACIDS IS DISCUSSED.GROWTH OF THE CRICKET, CRYLLODES SIGILLATUS, WAS SHOWN TO BE INHIBITED BY FATTY ACIDS & SOME FATTY ACID METHYL ESTERS. THE ROUTE OF ENTRY APPEARED TO BE THROUGH THE CUTICLE OF THE TARSI. Methyl Oleate SIGNIFICANTLY RETARDED GROWTH, & RESULTED IN LOWER SURVIVAL.Methyl Oleate was found to be negative when tested for mutagenicity using the Salmonella/microsome preincubation assay, using the standard protocol approved by the National Toxicology Program (NTP). Methyl Oleate was tested in as many as 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of rat and hamster liver S-9, at doses of 0.100, 0.333, 1.000, 3.333, and 10.000 mg/plate. The highest negative dose tested in any S. typhimurium strain was 10.000 mg/plate. Slight clearing of the background bacterial lawn occurred at the high dose in cultures without activation.Methyl Oleate’s production and use as a synthetic intermediate may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 6.3X10-6 mm Hg at 25 °C indicates Methyl Oleate will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase Methyl Oleate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 7.5 hours. Vapor-phase Methyl Oleate will also be degraded in the atmosphere by reaction with ozone; the half-life for this reaction is estimated to be 2.1 hours. Particulate-phase Methyl Oleate will be removed from the atmosphere by wet and dry deposition. If released to soil, Methyl Oleate is expected to have no mobility based upon an estimated Koc of 62,000. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry’s Law constant of 0.014 atm-cu m/mole. However, adsorption to soil is expected to attenuate volatilization. Methyl Oleate is expected to rapidly biodegrade in aerobic soils as suggested by the rapid biodegradation of structurally similar long-chain fatty acid esters. If released into water, Methyl Oleate is expected to adsorb to suspended solids and sediment in the water column based upon the estimated Koc. Methyl Oleate is expected to rapidly biodegrade in aerobic waters as suggested by the rapid biodegradation of structurally similar long-chain fatty acid esters. Volatilization from water surfaces is expected to be an important fate process based upon this compound’s estimated Henry’s Law constant. Estimated volatilization half-lives for a model river and model lake are 5 hours and 7 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is estimated to be about 61 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 18 months. An estimated BCF of 490 suggests the potential for bioconcentration in aquatic organisms is moderate. An estimated base-catalyzed second-order hydrolysis rate constant of 0.011 L/mole-sec corresponds to half-lives of 2 years and 74 days at pH values of 7 and 8, respectively. Occupational exposure to Methyl Oleate may occur through inhalation and dermal contact with this compound at workplaces where Methyl Oleate is produced or used. (SRC)Methyl Oleate’s production and use as a synthetic intermediate(1) may result in its release to the environment through various waste streams.TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that Methyl Oleate is expected to be immobile in soil(SRC). Volatilization of Methyl Oleate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry’s Law constant of 0.014 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Methyl Oleate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.3X10-6 mm Hg(4). Methyl Oleate is expected to rapidly biodegrade in aerobic soils as suggested by the rapid biodegradation of structurally similar long-chain fatty acid esters(5-7).Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that Methyl Oleate is expected to adsorb to suspended solids and sediment in water(SRC).Methyl Oleate is expected to rapidly biodegrade in aerobic soils as suggested by the rapid biodegradation of structurally similar long-chain fatty acid esters(8-10). An estimated base-catalyzed second-order hydrolysis rate constant of 0.011 L/mole-sec(9,SRC) corresponds to half-lives of 2 years and 70 days at pH values of 7 and 8, respectively(11).According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), Methyl Oleate, which has a vapor pressure of 6.3X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase Methyl Oleate 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 7.5 hours(SRC) from its estimated rate constant of 7.4X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase Methyl Oleate is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for this reaction in air is estimated to be 2.1 hours(SRC) from its estimated rate constant of 1.3X10-16 cu cm/molecule-sec at 25 °C(3). Particulate-phase Methyl Oleate may be removed from the air by wet and dry deposition(SRC).The rate constant for the vapor-phase reaction of Methyl Oleate with photochemically-produced hydroxyl radicals has been estimated as 7.4E-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 7.5 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of Methyl Oleate with ozone has been estimated as 1.3X10-16 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 2 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). A base-catalyzed second-order hydrolysis rate constant of 0.11 L/mole-sec(SRC) was estimated using a structure estimation method(3); this corresponds to half-lives of 2 years and 70 days at pH values of 7 and 8, respectively(3). The predicted near-surface half-life for the photosensitized oxidation of Methyl Oleate in near suface waters in the Southern US is 1100 hrs(4). Methyl Oleate is not expected to directly photolyze due to the lack of absorption in the environmental UV spectrum(5).An estimated BCF of 490 was calculated for Methyl Oleate(SRC) using a log Kow of 7.45(1) and a regression-derived equation(2). According to a classification scheme(3), the estimated BCF suggests the potential for bioconcentration in aquatic organisms is moderate.Using a structure estimation method based on molecular connectivity indices(1), the Koc for Methyl Oleate can be estimated to be about 62,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that Methyl Oleate is expected to be immobile in soil.The Henry’s Law constant for Methyl Oleate is estimated as 0.014 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry’s Law constant indicates that Methyl Oleate is expected to volatilize rapidly from water surfaces(2). 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)(2) is estimated as approximately 5 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)(2) is estimated as approximately 7 days(SRC). The volatilization half-life from a model pond 2 m deep is estimated to be about 61 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 18 months(3). Methyl Oleate’s Henry’s Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Methyl Oleate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.3X10-6 mm Hg(4).Methyl Oleate was detected in trace quantities in samples from the River Lee, in the UK(1).Methyl Oleate was identified in 3 of 3 New Jersey POTW effluents, date not provided, at a estimated concentration of 0.3-18 ppb(1). It was detected in 13 of 13 effluents samples from an olive oil production plant, Spain, at 520-77721 ug/l(2). It was qualitatively detected in the effluent of a pulp and paper mill in Finland(3).

Güney ABD’de Metil Oleat a duyarl hale getirilmi oksidasyonu için öngörülen yüzeye yakn yarlanma ömrü 1100 saattir (4). Metil Oleat, çevresel UV spektrumunda absorpsiyon eksikliinden dolay dorudan fotolize olmas beklenmemektedir (5). 7.45’lik bir log Kow kullanlarak Metil Oleat (SRC) için 490’lk tahmini bir BCF hesaplanmtr. (1) ve regresyondan türetilmi bir denklem (2). Bir snflandrma emasna (3) göre, tahmini BCF, suda yaayan organizmalardaki biyokonsantrasyon potansiyelinin orta düzeyde olduunu göstermektedir. Moleküler balant indekslerine (1) dayal bir yap tahmin yöntemi kullanlarak, için Koç Metil Oleat yaklak 62.000 (SRC) olabilir. Bir snflandrma emasna (2) göre, bu tahmini Koç deeri, Metil Oleat toprakta hareketsiz olmas beklendiini göstermektedir.Metil Oleat için Henry Yasas sabiti, 0.014 atm-cu m / mol olarak tahmin edilmektedir. (SRC) bir parça sabiti tahmin yöntemi (1) kullanarak. Bu Henry Yasas sabiti, Metil Oleat su yüzeylerinden hzla buharlamasnn beklendiini gösterir (2). Bu Henry Yasas sabitine dayanarak, bir nehir modelinden (1 m derinliinde, 1 m / sn akan, 3 m / sn rüzgar hz) (2) buharlama yar ömrü yaklak 5 saat (SRC) olarak tahmin edilmektedir. Bir gölden modeldeki uçuculuk yar ömrü (1 m derinlik, 0,05 m / sn akma, 0,5 m / sn rüzgar hz) (2) yaklak 7 gün (SRC) olarak tahmin edilmektedir. 2 m derinliindeki bir model havuzdan buharlama yar ömrünün, adsorpsiyon göz ard edilerek yaklak 61 saat olduu tahmin edilmektedir; maksimum adsorpsiyon düünüldüünde uçuculuk yarlanma ömrü 18 aya çkar (3). Metil Oleat Henry Yasas sabiti (1), nemli toprak yüzeylerinden buharlamann (SRC) meydana gelebileceini gösterir. Metil Oleat 6,3X10-6 mm Hg (4) buhar basncna bal olarak kuru toprak yüzeylerinden (SRC) buharlamas beklenmemektedir. Nehirden alnan numunelerde eser miktarlarda Metil Oleat tespit edilmitir.
