Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.

- Toxicity Summary: IDENTIFICATION AND USE: 2-Dimethylaminoethanol (DMAE) is a colorless liquid. DMAE has been used as an ingredient in skin care, and in cognitive function- and mood-enhancing products. Deaner(DMAE p-acetamidobenzoate) was a U.S. prescription drug for more than 20 years until 1983 when it was withdrawn from the market. It was used to treat children with learning and behavior problems. A large number of dietary supplements contain DMAE. The predominant form, when specified, is DMAE bitartrate. DMAE has applications in the chemical and pharmaceutical industries. HUMAN EXPOSURE AND TOXICITY: Severe respiratory symptoms were observed in a single painter exposed to spray paint containing DMAE. Wheal and flare responses occurred after exposure of human volunteers to DMAE but it was interpreted as an irritant. DMAE tartrate administered orally to humans produced mild mental stimulation. At 20 mg/day, there was a gradual increase in muscle tone and perhaps an increased frequency of convulsions in susceptible individuals. Larger doses produced insomnia, muscle tenseness, and spontaneous muscle twitches. Serious cholinergic side effects were reported in a 37-yr-old woman with tardive dyskinesia Source: Hazardous Substances Data Bank (HSDB)
- Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for 2-dimethylaminoethanol(SRC), using a log Kow of -0.55(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). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 2-dimethylaminoethanol is expected to have very high mobility in soil(SRC). The pKa of 2-dimethylaminoethanol is 9.3(3). At pH 8.2, 20% will be the free amine. Thus, this compound will exist almost entirely in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(4). As a result, 2-dimethylaminoethanol may have greater adsorption and less mobility than its estimated Koc value indicates. Volatilization of 2-dimethylaminoethanol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.8X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(2). 2-Dimethylaminoethanol may volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.18 mm Hg at 25 °C(5). A 60.5% of theoretical BOD in two weeks using activated sludge in the Japanese MITI test indicates that 2-dimethylaminoethanol is readily biodegradable(6) and suggests that biodegradation is an important environme Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 2-dimethylaminoethanol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.8X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). According to a classification scheme(4), an estimated BCF of 3(SRC), from its log Kow of -0.55(5) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 60.5% of theoretical BOD in two weeks using activated sludge in the Japanese MITI test indicates that 2-dimethylaminoethanol is readily biodegradable(6) and suggests that biodegradation is an important environmental fate process in soil(SRC). Results of another screening test found that 2-dimethylaminoethanol biodegrades readily(7). 2-Dimethylaminoethanol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-dimethylaminoethanol, which has a vapor pressure of 3.18 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-dimethylaminoethanol 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 4.3 hours(SRC), calculated from its rate constant of 9.0X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase 2-dimethylaminoethanol is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for this reaction in air is estimated to be 1.7 days(SRC), calculated from its rate constant of 6.71X10-18 cu cm/molecule-sec at 25 °C(3).
