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. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whene Source: CAMEO Chemicals

  • Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
  • Toxicity Summary: IDENTIFICATION AND USE: Triethanolamine (TEA) is a colorless, or pale yellow viscous liquid. Triethanolamine is used in the manufacture of emulsifiers and dispersing agents for textile specialties, agricultural chemicals, waxes, mineral and vegetable oils, paraffin, polishes, cutting oils, petroleum demulsifiers, and cement additives. It is an intermediate for resins, plasticizers, and rubber chemicals. It is used as a lubricant in the textile industry, as a humectant and softening agent for hides, as an alkalizing agent and surfactant in pharmaceuticals, as an absorbent for acid gases, and in organic syntheses. It can be useful for rapid detection and identification of chemical warfare agents. TEA has been tested as experimental therapy. HUMAN EXPOSURE AND TOXICITY: Triethanolamine produce mild skin irritation only in concentrations above 5%. It has not been shown to be a sensitizer. Triethanolamine has been identified as causing allergic contact dermatitis, erythematous vesicular lesions, eczema, contact dermatitis, and irritation in workers exposed to triethanolamine in their occupations. A total of 1,357 patients suspected of having allergic eczematous contact dermatitis were p Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: BCFs of <0.4 and <3.9 were reported using carp (Cyprinus carpio) which were exposed to respective concentrations of 2.5 and 25 ppm of triethanolamine over a 6-week period(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that triethanolamine is expected to have very high mobility in soil(SRC). The pKa of triethanolamine is 7.76(3), indicating that this compound will exist partially in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the cation from moist soil is not expected because cations do not volatilize(SRC). Volatilization of neutral triethanolamine from moist soil surfaces is not expected (SRC) given an estimated Henry's Law constant of 7X10-13 atm-cu m/mole(SRC), based upon its vapor pressure, 3.59X10-6 mm Hg(5), and assigned value for water solubility of 1X10+6 mg/L (miscible)(6). Triethanolamine is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(5). Triethanolamine may biodegrade in soil based on a number of screening tests with results of no biodegradation using the Japanese Ministry of International Trade and Industry (MITI) test for 14 days(7) to 97% using the French Association fo Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that triethanolamine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 7.76(3) indicates triethanolamine will exist partially in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces of the cation is not expected to be an important fate process(SRC). Volatilization of neutral triethanolamine from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 7X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 3.59X10-6 mm Hg(5), and assigned value for water solubility of 1X10+6 mg/L (miscible)(6). Triethanolamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). According to a classification scheme(7), BCFs of <0.4 and <3.9 measured in carp(8), suggest bioconcentration in aquatic organisms is low. Triethanolamine reached 70% of its Theoretical oxygen demand after 10 days in acclimated Kanawha River water using a sewage inoculum(9), suggesting that biodegadatio 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), triethanolamine, which has a vapor pressure of 3.59X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase triethanolamine 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 3.5 hours(SRC), calculated from its rate constant of 1.1X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase triethanolamine may be removed from the air by wet and dry deposition(SRC). Triethanolamine 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).
