Monoethanolamine (MEA) is present in nature as a nitrogenous base in phospholipids. These lipids, composed of glycerol, two fatty acid esters, phosphoric acid, and MEA, are the building blocks of biomembranes in animals. MEA is methylated to form choline, another important nitrogenous base in phospholipids and an essential vitamin. The rat dietary choline requirement is 10 mg/kg/d.
... The backbone of a phospholipid molecule /of the eukaryotic cell membrane/ is glycerol with ... the third /-OH/ group esterified by a phosphate group and a nitrogenous compound (... ethanolamine ...).
/Ethanolamine/ is an endogenous alkanolamine biosynthesized from serine by decarboxylation. It is a principal precursor of phosphoglycerides, which are important elements in the structure of biologic membranes, and choline.
The half-life of the persistent low level of radioactivity in the blood /of dogs administered 14C-ethanolamine/ was 19 days.
Labeled MEA was administered to dogs. ... After 24 hr ... the half-life was 19 days.
Ethanolamine can be used as a source of carbon and nitrogen by phylogenetically diverse bacteria. Ethanolamine-ammonia lyase, the enzyme that breaks ethanolamine into acetaldehyde and ammonia, is encoded by the gene tandem eutBC. Despite extensive studies of ethanolamine utilization in Salmonella enterica serovar Typhimurium, much remains to be learned about EutBC structure and catalytic mechanism, about the evolutionary origin of ethanolamine utilization, and about regulatory links between the metabolism of ethanolamine itself and the ethanolamine-ammonia lyase cofactor adenosylcobalamin. We used computational analysis of sequences, structures, genome contexts, and phylogenies of ethanolamine-ammonia lyases to address these questions and to evaluate recent data-mining studies that have suggested an association between bacterial food poisoning and the diol utilization pathways. We found that EutBC evolution included recruitment of a TIM barrel and a Rossmann fold domain and their fusion to N-terminal alpha-helical domains to give EutB and EutC, respectively. This fusion was followed by recruitment and occasional loss of auxiliary ethanolamine utilization genes in Firmicutes and by several horizontal transfers, most notably from the firmicute stem to the Enterobacteriaceae and from Alphaproteobacteria to Actinobacteria. We identified a conserved DNA motif that likely represents the EutR-binding site and is shared by the ethanolamine and cobalamin operons in several enterobacterial species, suggesting a mechanism for coupling the biosyntheses of apoenzyme and cofactor in these species. Finally, we found that the food poisoning phenotype is associated with the structural components of metabolosome more strongly than with ethanolamine utilization genes or with paralogous propanediol utilization genes per se.

A number of aliphatic amines have been identified as normal constituents of mammalian and human urine, including ethanolamine(1). Average excretion rate: men - 0.162 mg/kg per day; women - 0.492 mg/kg per day; cats 0.47 mg/kg per day; rats - 01.46 mg/kg per day; and rabbits - 1.0 mg/kg per day(1).
... Here we investigated hair dye-induced dermatitis and hair loss using in vivo mouse model to uncover the causative ingredients. Commercially available hair dye products or combination of the ingredients of hair dye product were applied topically for 3 days on the dorsum of the female C57BL/6 mice and, dermatitis and hair loss were examined. The mice treated with hair dye products exhibited unequivocal signs of hair loss and dermatitis. To find out causative ingredients, combinations of the representative components of hair dye including reducing agents, the mixture of dye and monoethanolamine (MEA), ammonia, and hydrogen peroxide (H(2)O(2)) were applied and thereafter, hair loss and dermatitis were evaluated. All the groups treated with the combinations containing H(2)O(2) and neutralized dye mixture manifested hair loss and dermatitis. Subsequent experiments revealed that H(2)O(2) and MEA synergistically induced hair loss and dermatitis. Histological examination showed that oxidative stress may be the mechanism underlying hair-dye induced dermatitis. Consistently, H(2)O(2) and MEA synergistically induced oxidative stress and cytotoxicity in human keratinocytes. These results suggest that H(2)O(2) and MEA may be the key causative ingredients for hair dye-associated dermatitis and hair loss.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 0.59(SRC), determined from a log Kow of -1.31(2) and a regression-derived equation(3), indicates that 2-aminoethanol is expected to have very high mobility in soil(SRC). However, absorption is affected by the acidity of the soil(SRC). The pKa of 2-aminoethanol is 9.5(4), indicating that this compound will exist almost in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization from moist soil is not expected because the compound exists as a cation and cations do not volatilize. 2-aminoethanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.404 mm Hg at 25 °C(6). Using the Closed Bottle, CO2 Evolution, and MITI tests, 2-aminoethanol exhibited 64.4, 91.4, and 71.2% CO2 evolution, respectively, after 28 days(7), suggesting that biodegradation is an important environmental fate process in soil(SRC).
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 0.59(SRC), determined from a log Kow of -1.31(2) and a regression-derived equation(3), indicates that 2-aminoethanol is not expected to adsorb to suspended solids and sediment(SRC). However, adsorption can be affected by the acidity of the substrate(SRC). A pKa of 9.5(4) indicates 2-aminoethanol will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(5), an estimated BCF of 3.2(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Using the Closed Bottle, CO2 Evolution, and MITI tests, 2-aminoethanol exhibited 64.4, 91.4, and 71.2% CO2 evolution, respectively, after 28 days(6), 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), 2-aminoethanol, which has a vapor pressure of 0.404 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-aminoethanol 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 3.6 hours(SRC), calculated from its rate constant of 3.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 2-Aminoethanol 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 substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

IDENTIFICATION AND USE: 2-Aminoethanol is a colorless, viscous liquid or solid (below 51 °F). It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. The dual function groups, amino and hydroxyl, make it useful in cutting fluids and as intermediates in the production of surfactants, soaps, salts, corrosion control inhibitors, and in pharmaceutical and miscellaneous applications. 2-Aminoethanol and other amines appear to be potentially useful components of topical formulations used to decontaminate and protect the skin against chemical warfare agents. As a pharmaceutical adjuvant, it is used as a solvent for fats and oils, and in combination with fatty acids forms soaps in the formulations of various types of emulsion such as lotions and creams. It is used in hydraulic fracturing. HUMAN EXPOSURE AND TOXICITY: A concentration of 5.9% is irritating to human skin. Symptoms associated with CNS depression in humans include increased blood pressure, diuresis, salivation, and pupillary dilation. Large doses produce sedation, coma, and death following depression of blood pressure and cardiac collapse. 2-Aminoethanol inhalation by humans has been reported to cause immediate allergic responses of dyspnea and asthma and clinical symptoms of acute liver damage and chronic hepatitis. ANIMAL STUDIES: Undiluted liquid causes redness and swelling when applied to the skin of the rabbit. Administration of 2-aminoethanol by the intravenous route in dogs produced increased blood pressure, diuresis, salivation, and pupillary dilation. Rats, mice, rabbits, and guinea pigs exposed to vapor or mist at high concentrations (up to 1250 ppm) developed pulmonary, hepatic, and renal lesions. In a 90-day subacute oral toxicity study of 2-aminoethanol in rats that a maximum daily dose of 0.32 g/kg resulted in no effect; 0.64 g/kg/day resulted in altered liver or kidney wt; and at 1.28 g/kg death occurred. It is considered to be liver toxin. No treatment-related effects were noted in dogs administered as much as 22 mg/kg/d of 2-aminoethanol for 2 yr. In developmental studies in rabbits maternal toxicity was seen at the two higher dose levels (25, 75 mg/kg body weight) as skin irritation and at the highest dose level as reduced weight gain. There was no treatment related effect on the incidence of any fetal variation or malformation or on the number of malformed fetuses. 2-Aminoethanol has been demonstrated to be non-mutagenic in the Ames Salmonella typhimurium assay, with and without S9 metabolic activation, using TA 1535, TA 1537, TA 1538, TA 98, and TA 100; and also negative in the Escherichia coli assay, Saccharomyces gene conversion assay, and rat liver chromosome assay. ECOTOXICITY STUDIES: Aquatic toxicity tests were conducted using zebra fish fry (Brachydanio rerio) and the unicellular algae Isochrysis galbana (a flagellate) and Chaetoceros gracilis (a diatom). Inhibition of cell division, chlorophyll content, and (14)CO2 uptake in the algae were sensitive end points. 2-Aminoethanol had an LC50 /in the zebra fish fry/ higher than 5,000 mg/L.
/AQUATIC SPECIES/ Monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) are compounds with potential acute, sub-chronic and chronic toxicity effects towards aquatic species. A literature review highlighted the existence of a gap in the knowledge on their toxicity with saltwater testing species. A battery of toxicity tests including the alga Phaeodactylum tricornutum Bohlin, the bivalve molluscs Crassostrea gigas (Thunberg) and Mytilus galloprovincialis (Lmk), and the crustacean Artemia franciscana, was considered to update and improve the existing ecotoxicological information. Data were provided as the Effective Concentration that induces a 50% effect in the observed population (EC50), Lowest Observed Effect Concentration (LOEC) and No Observed Effect Concentration (NOEC). EC50, LOEC and NOEC values were compared with a reviewed database containing the existing ecotoxicological data from saltwater organisms.
/AQUATIC SPECIES/ The influence of monoethanolamine (MEA) as a CO(2) absorbent on photoautotrophic culture of CO(2)-fixing microalgae was investigated. When 300 ppm MEA (4.92 mM) was added to blank culture medium, the dissolved inorganic carbon and the molar absorption ratio increased to 51.0 mg/L and 0.34 mol CO2 = mol MEA, respectively, which was an almost 6-fold increase in CO(2) solubility. When free MEA up to 300 mg/L was added to a green alga Scenedesmus sp. culture that was supplied 5% (v/v) CO(2) at 0.1 vvm, both cell growth rate and final cell density were enhanced compared to when no MEA was added. The cell growth rate reached 288.6 mg/L/d, which was equivalent to 539.6 mg CO(2)/L/d as a CO(2)-fixation rate and enhancement of about 63.0% compared to not adding MEA. Chlorophyll-a content and nitrate consumption rate increased correspondingly. MEA doses higher than 400mg/L inhibited cell growth, probably due to toxicity of the carbamate intermediate.
/AQUATIC SPECIES/ ... Aquatic toxicity tests were conducted using zebra fish fry (Brachydanio rerio) and the unicellular algae Isochrysis galbana (a flagellate) and Chaetoceros gracilis (a diatom). Inhibition of cell division, chlorophyll content, and (14)CO2 uptake in the algae were sensitive end points. ... Monoethanolamine had an LC50 /in the zebra fish fry/ higher than 5,000 mg/L.
/PLANTS/ The cowpea aphid Aphis craccivora that infests the black locust Robinia pseudoacacia shows toxicity to its predator, the multicolored Asian ladybird beetle, Harmonia axyridis. In contrast, the same aphid species that infests the common vetch, Vicia angustifolia, is suitable prey for H. axyridis larvae. Previously, it was reported that the toxicity of A. craccivora infesting R. pseudoacacia was due to canavanine and 2-aminoethanol, but there was some doubt about the toxicity of these compounds and their concentrations in the aphids. In the present study, we determined the concentrations of cyanamide, canavanine, and 2-aminoethanol in A. craccivora infesting the two host plants. In the extracts of A. craccivora that infested either of the host plants, canavanine was undetectable, and 2-aminoethanol was detected at the concentration of 3.0-4.0 ug/g fresh weight. Cyanamide was detected in the extract of A. craccivora that infested R. pseudoacacia (7.7 ug/g fresh weight) but not in that infesting V. angustifolia. The toxicity of canavanine, 2-aminoethanol, and cyanamide was evaluated against H. axyridis larvae in a bioassay by using an artificial diet containing these compounds at various concentrations. Cyanamide exhibited 10-100 times stronger toxicity than canavanine and 2-aminoethanol. These results indicate that the toxicity is at least partly due to cyanamide, which is present in the toxic A. craccivora that infests R. pseudoacacia but absent from the non-toxic A. craccivora that infests V. angustifolia.

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 safety 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. 2-Aminoethanol is found on List D. Case No: 4032; Pesticide type: Fungicide, antimicrobial; Case Status: No products containing the pesticide are actively registered. Therefore, we are characterizing the case as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.; Active ingredient (AI): 2-Aminoehtanol; AI Status: The active ingredient is no longer contained in any registered products. Thus, we characterize it as "cancelled."
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. Ethanolamines are produced, as an intermediate or a final product, by process units covered under this subpart. /Ethanolamines/
Forty percent of (15)N-labeled ethanolamine appears as urea within 24 hr when it is given to rabbits, suggesting that it is deaminated. In rat liver homogenates, ethanolamine undergoes demethylation yielding formaldehyde.
Ethanolamine is a normal intermediate in the metabolism of some animal species, having a part in the formation of phospholipids and choline.
The distribution and metabolism of topical (14)C ethanolamine was studied in vivo, using athymic nude mice, human skin grafted onto athymic nude mice, and in vitro, using excised pig skin. Ethanolamine was the only radioactive phospholipid base detected in the human skin grafts, in the mouse skin, and in the pig skin. Ethanolamine that penetrated human skin grafts or mouse skin was extensively metabolized in the animal. The liver is a major site for metabolism of ethanolamine, containing over 24% of the applied radioactive dose. The kidneys, lungs, brain, and the heart contained 2.53, 0.55, 0.27, and 0.15% of the dose, respectively. Hepatic, human skin graft, and mouse skin proteins were also highly radioactive. Over 18% of the topical radioactive dose oxidized to (14)CO2 and 4.6% was excreted in the urine over 24 hr. Urea, glycine, serine, choline, and uric acid were the urinary metabolites of ethanolamine.

Ethanolamine is a Sclerosing Agent. The mechanism of action of ethanolamine is as a Sclerosing Activity. The physiologic effect of ethanolamine is by means of Vascular Sclerosing Activity.
The principal route of exposure is through skin, with some exposure occurring by inhalation of vapor and aerosols. Monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) in water penetrate rat skin at the rate of 2.9 x 10(-3), 4.36 x 10(-3) and 18 x 10(-3) cm/hr, respectively. MEA, DEA, and TEA are water-soluble ammonia derivatives, with pHs of 9-11 in water and pHa values of 9.3, 8.8, and 7.7, respectively.
The excretion rate in men was found to vary between 4.8 and 22.9 mg/day with a mean of 0.162 mg/kg /body weight/. 11 women were observed to excrete larger amounts, varying between 7.7 and 34.9 mg/day with a mean excretion rate of 0.492 mg/kg/day. The excretion rates in animals were approximately, for cats, 0.47 mg/kg/day; for rats, 1.46 mg/kg/day; and for rabbits, 1.0 mg/kg/day. From 6-47% of monoethanolamine administered to rats can be recovered in the urine.
Persistence of low levels of radioactivity in dog whole blood was obtained after admin of (14)C-labeled ethanolamine. Excretion of radioactivity as % of dose in dog urine was 11. After 24 hr total blood radioactivity as % of dose was 1.69.
/Ethanolamine/ is a normal urine constituent in man, excreted at a rate of 5-23 mg/day ... 40 percent of an administered dose is deaminated and excreted as urea.

Alkanolamines are typically manufactured from the corresponding olefin oxide and ammonia. Mono-, di-, and trialkanolamines are produced in the reactor and sent to downstream distillation columns for separation. The oxide-ammonia reaction is exothermic. Reaction rates decrease with increased carbon number of the oxide (ethylene oxide > propylene oxide > butylene oxide). Anhydrous or aqueous ammonia may be used, although anhydrous ammonia is typically used to favor monoalkanolamine production. Using anhydrous ammonia requires that the reactor be operated at higher temperature and pressure. Varying the ammonia to oxide ratio is the primary way to shift the product split among the mono-, di-, and trialkanolamines. A high ammonia to oxide ratio favors mono- production.
Prepared on a large scale by ammonolysis of ethylene oxide; ... also from nitromethane and formaldehyde.

Each year, an estimated 35,000 wells are hydraulically-fractured in the U.S. Although the oil and gas extraction industry as a whole has a relatively higher fatality rate compared to most of the U.S. general industry... there is currently no worker injury/illness or fatality data publicly available for hydraulic fracturing or flowback operations. Regardless of the availability of data, more workers are potentially exposed to the hazards created by hydraulic fracturing and flowback operations due to the large increase in the number of these operations in the past decade. /Hydraulic fracturing/
